"Then I will arrange the personnel, advise the residents of the territory, check the situation, and arrange the necessary materials for the filtration system."　Natalia tells Estella and bows her head. 　I don't think I've recovered from my illness. "Natalia, you may use my umbrella,""But then,""There are people here, and besides, it would be terrible if Natalia's cold came back.""...Yes, sir. Thank you for your concern."　Natalia bowed her head deeply. Her expression seemed to be somewhat satisfied. "The rain is getting weaker."　Jeanette, looking out the window, says such a thing. 　The sound of rain against the window was certainly a little quiet. 　After Umaro came, we had a full-fledged meeting. 　It was a good time to eat Jeanette's breakfast. 　"I called Regina, but when I ate in the children's room, she said, ""I can't eat anywhere I don't know.""" 　Shouldn't he train his communication a little more?　Then, after discussing the structure of the filtration system and its future movements, Natalia returned to the lord's residence to prepare. 　For now, the top priority is not to cause any more victims. 　Next is securing drinking water for the residents. "Mr. Jiro, this filter is pretty big, isn't　Womaro draws his eyebrows with my drawing of the filter. "You can't make it unless you have this size and a lot of space. Of course, it's indoors where it doesn't rain.""Don't you have a workshop?""Yes, but it's very hard to carry this size to 42 wards. If possible, I want a place to work in 42 wards."　The filtration system commissioned by Womaro is quite large. 　A tank two meters high and 80 centimeters in diameter is joined by four 80 centimeters high filtration systems, which are connected by a gentle sloping channel. 　First, the tank is filled with water, where a certain amount of dirt and dirt is precipitated, then slowly passed through the sealed waterway, which is created at an infinitely gentle slope, while the impurities that have not been removed are precipitated and only the less dirty supernatant is sent to the filter. 　This filter is made by laying fibers, charcoal, sand, gravel and pebbles in the barrel and attaching a cock to the bottom of the barrel so that filtered water can be poured into a container prepared under the barrel if something goes wrong with the filter, because it is intolerable that filtered water will be spoiled by the 'problematic water' that is poured in later. 　They asked for a relatively large‐scale device, which they set up in a place like a lord's house or church to provide water. 　Of course, it will take some time to complete, so we're going to build only the barrel filtration system first, and we're going to provide water this afternoon. 　This device is then designed to automatically filter water until post‐disaster treatment and reconstruction are complete, though it is manual to store water in the tank. "Can't you rent the lord's residence?""I don't think it's possible. There's no room in the room to make something this big."　When it comes to building equipment, you'll need a lot of space to bring in wood, put it together, and work. 　When I was in Japan, I used to make bookshelves, but I remember that the six tatami mat room was too small to make. The space to expand the materials was quite wide. "Then how about here?"　The church lounge and kitchen might do something about it. 　But..."The children are still asleep, so please refrain from making noise."　Bertina refuses politely but resolutely. 　Well, I don't know how many days it will take, but it's hard not to be able to use the kitchen and the lounge. 　It's cruel to put up with children after they get sick. "Well, Mr. Yashiro, if you're going to use the Yodamari-tei...? That's what it is, and we're going to close the store for a while..."　I think Jeanette's idea makes the most sense. 　...it can't be helped, do you use the Yodamari-tei? "If you scratch it, repair it for free.""It's almost like the Oylas have renovated it for almost nothing."　What do you say? You're paying me right!　He's an unpopular man. "If I were to use the filter at Yodamari-tei, I wouldn't be happy with just one of them. I'd rather have two more.""Well, if it's just drinking water, I think we can cover it in some way, but when it comes to water for daily use in general...."　Drinking water requires water to be used for cooking, if you drink sake. 　I'll have you put up with washing and taking a bath. 　Eating and drinking are paramount. "The rest is ingredients,"　Estella mutters with a difficult expression. "I think you'll get stones and gravel when you go to the river.""But I heard that this rain has increased the river and kept it out of bounds. Mr. Delia used to say."　Estella, struggling to procure materials, becomes even more clouded when Jeanette points it out. "It's all right, Jeanette. There's an Omero in the river-fishing guild.""Are you good at swimming?"　Well, don't you know Jeanette? "Omero is a man who will be safe in case of emergency!""You can'　Because the other day you were washed in the river just because you couldn't swim.　Huh? Were you taught to swim?"Oh, may I have a moment?"　I was going to explain that Omero's position was the same as that of Shogi Ayumu and Chess Pawn, when Loretta raised her hand. "You can get them in our neighborhood, like stones and gravel, and dry sand.""Really!""Yes, yes!"　Loretta shakes when Estella approaches her. "Loretta, it's all right. It's surprisingly flat, but it's a woman.""Oh, no. I know. I'm just surprised at the loud voice.""First of all, Jiro... It's raining, shall I show it?""I'm sorry, Estella. If I get wet in the rain, my skin will shrink.""What's the matter with straight hair?"　a groaning estella 　Oh, my God, he's... frustrated by the little things... I'll give him a crack. "Astella. Don't get irritated just because you're small.""Who's annoying!"　Oh, my God! I just said it a little wrong. 'Don't be irritated by small things,''Don't be irritated just because you're small,'　It's almost the same, but... strange. "Well, then, there's a cave that my brothers dug up in our neighborhood...""Cave?"　The word that bothered me a little made me ask. 　What's the cave that the younger members dug?　What are you digging for?"There is a cliff between the twenty-ninth district and the twenty-ninth district. That's where my younger brothers play."　Hole digging game?　Well, it must be fun to be like a secret base. "There's no rain and sand coming in there.""Then shall we go and see it?"　It's just a matter of looking at it before you know if it can use it. 　When I left the church, the rain had eased a little. At this rate, it might stop raining this afternoon. 　If it rains, it's easy to take action. 　We moved to the slums, thinking that we should have made a Teltel priest. "Here,""'Oh, my dear fellow said,Oh, my gosh!"　At the sight of the cave guided by Loretta, I and Umaro cried. We couldn't help but raise our voices. 　It was a huge cave, like a subterranean kingdom. 　Even if you say it's the home of the dragon, I believe it. "Did your brothers make these?""Yes, I'm free every day."　Estella breathes with astonishment and admiration. 　It was a space large enough to accommodate the concert hall, and it was a space where the 29th Ward building above was worried about subsidence. 　The ceiling is high enough to make me wonder how you dug it. "The water supply in this area is not that good, and the houses are run down, so if it rains heavily, people evacuate here."　When I was told to look around, there were certainly household goods lying here and there. "And what about your family now?""...they run wild when they come, so I'm ordering them to stay at home."　I see. It may be a wise decision. "What do you think? Can you use the stones and sand around here?""Oh, no problem. This is enough.""... carried by Magda,"　Magda, the most dependable of all, thumped on the chest in hard work. 　This guy would do the job of a ten-ton car. "And, if you have firewood, why don't you burn firewood here and mass-produce charcoal, and your younger brothers will be warm and you'll have two birds with one stone?"　I don't think I'll have a problem if it's this big. . . . ."Let's not do that. If you should get addicted to carbon monoxide, you'll be in trouble.""Is it "Isn't it?"　Oh... You don't have it, do you mean carbon monoxide poisoning?　That's dangerous, isn't it? "If you burn a lot of fire in a sealed place like a cave, you lose oxygen and you get carbon monoxide. If you inhale a lot of that carbon monoxide, you lose your life.""What!? We make fires here all the time!?""I don't mind a little,"　This cave has a fairly wide doorway. However, it's a huge cliff, so there's no place for air to pass except for the doorway. That's a little scary. "It's all right to do a little near the entrance, but it's dangerous to make too much fire.""Oh... As expected, brother. You know everything."　It's nothing. 　Don't plant such a dependable character on me. "Let's leave the charcoal to the church. I'm sure the sisters will be making it for us by now."　The kitchen in the church has a chimney and ventilation. It's much safer there, though I think it's very hot. "But now you have all the ingredients?""Oh, I think we should wash old clothes and underwear for fiber.""Well, Mr. Yashiro... worn-out underwear is a little...."　If it's Genet or Estella, I think there might be a special charge, but if it's from Umaro, it'll be poisoned water. "I'll get you the cleanest cloth you can get before you turn it into clothes."　says Estella, a big, thin-chested man. 　As expected, rich people say differently. "Hey, thin chest! Oh, I made a mistake. Hey, big belly!""That's definitely a mistake, isn'　He cares about every little thing. In two ways. "Will the people of the city be happy when the filtration system is completed?""Of course, Jeanette. I'm sure we can save many people from grief and suffering.""Yes, that's right."The lord responsible for the inhabitants' lives and the philanthropic Spiritual Church members are holding hands to help. 　Is this the sort of thing that will save those who believe? 　Then why have I been left out so far? I have no obligation to protect the lives of the people, no responsibility, no spirit of philanthropy. 　I can't do this unless you make a good profit from this. If things go according to my plan, I'll make a good profit. Please, 'God.' Save the time and give me generous benefits. I believe in you, too. I just hate you. 　But I think… 　Will it be possible to say that people have been saved just by securing drinking water?　In the first place, the structure of the well itself is wrong, isn't it?"Ah, Mr. Jiro!"　When a certain idea began to loom over me, a woman came to me with a sparkle in her eyes twinkled. 　...what a disgust! "Here, here, here, here...""'I want a lover'?""No, I want it, but it's not!"`Can't you get rid of the habit of exposing your lower abdomen in public?'"Oira doesn't have such a habit!"　Outraged, Umaro seems to have regained his normalcy for now. 　I took a deep breath and said in a clear tone: "I want you to lend it to the Tolbeck Works! You can make quite a lot of things here!"　Well, I'm sure. There's room here, there's no rain, and there's no problem with making noise. "Well, this cave is now a refuge for our family...""Please do something about it!""No, but my house is leaking so much... it's good for me to go home temporarily... It's going to take a long time to build that device, isn't it?""The oyla is leaking again!""Oh, no... as well as leaks, the floor and pillars are damaged... I think I'll repair them after the rainy season...""Slip! I'll make that house comfortable!""Well... well... my brother..."　Being overwhelmed by Umaro's power, Loretta turns to me for help. 　Well, I can't believe that a woman would devour a girl like that... I think she'd rather use this place. It's certainly a place where shipbuilding would be possible. "Womalo. There's no work at Tolbeck, is there?""It's partly because of the rainy season, but I can't work until the mess of Mr. Wishart in the 30th leg goes away. ... Mr. Wishart doesn't seem to care about time because it's someone else's business..."　Don't put in any other work and interfere with the work you've been doing. Wasn't that what Umaro used to say? 　If he wasn't a nobleman, he'd be quick to say no, but... if he was offended, he'd be in trouble later. No, he'd certainly be harassed. "Isn't there only a self-centered man, Estella?""Why are you talking to me?""I want to hear your opinion for your information,""Not everyone. Some lords put their inhabitants first. Is that all right?"　You've done a good job. 　Estella will not convict us of interrupting our work, even if we ask the umaro for a new job and resume our work in the middle. 　You can respond according to the circumstances. 　That's why I can squeeze my work into this gap now. 　......hmm. 　You might have come up with a good idea. "Attention Prizes!"　raise one's right hand straight and say loudly. 　Everyone shakes their shoulders and looks at me half-dumbfounded. "...what? All of a sudden, I'm surprised."　That's true. I'm so surprised that I'm chilling, Estella. "I have a very wonderful story to tell you,""...when Jillo looks like that.""... well, it's time for me to make a profit.""...and the strain is on the womalo,""Magda-tan called Oira's name! Oira, I'm so touched!""... No, ummallow. Is that okay with you? Is it because of your reaction? It's like... Well, if you're happy."　Talking Estella, Umaro and Magda. 　Loretta leaves a slightly uneasy look on her face. 　Among them, Jeanette was the only one to shine. "What? It's such a wonderful story. I want to hear it."　Yes, yes. You may be honest. "First of all, Loretta.""Yes, yes!"　I can't hide my nervousness about what you're saying. Loretta has a straight spine. 　Well, don't be so nervous. It's a good story for you, too. 　Anyway, it's a great plan to solve all your problems. 　It's everything. 　Well, I need a little bit of a price to pay for that. "Give this cave to the Torbeck Works,"`What!?' she said,"Loretta, there's a very wonderful story in my country called 'Kasa Jizo.' I don't want you to explain it because it's too much trouble, but I want you to give it to me as I told you.""If you leave out the contents, you won't be satisfied at all!""Ah... the point is that if you do something good first, it will come back many times.""Is there anything convenient for Jiro to say?"Hey, Estella. When would it be convenient for you?　My suggestions are always good for everyone but me. I'm making the most profit. "Mr. Yashiro, please tell me that story!""No, I don't have time...""... I want to hear Magda, too.""Me, too. You may understand me!""Yes..."　I had no choice but to tell everyone I knew about Kasa Jizo, like a kindergarten teacher. What is this shameful play?　Well, I emphasized how good the protagonist, Zizhi Babaa, lived a life of poverty but modesty, and finally, I tried to feel catharsis. 　As a result..."Uncle . . . . old man and old woman . . . . . . . . . good for you.""...I can't believe that the day will come when Jillo will cry.""...well, well,""Oh, Magda! Angels crying!"　be in tears 　I didn't expect Estella to shed tears, let alone the other two. 　And here's Loretta, of all importance.""What we lacked was the love that gave alms to someone... ...a little human being who only thought of themselves... ...I'm ashamed of myself! I'm ashamed of my family!"　I was reflecting on it for somehow. 　Well, what's most embarrassing is your parents who are giving up their children even though they're poor. "All right! This cave! I'll give it to the Tolbeck factory under the authority of the Great Black Pillar!""Really!? Good job!"　a woman who raises her hands in delight 　It's good to be in a good mood. This will make some sense. "So, Umaro, rebuild Loretta's house anew.""Yes! I'll give you a new house as a present!""Well, for the time being, I wonder if I can manage it if I have about five buildings.""Ah......... a building...?""It's a condominium. I'd rather have eight houses in one building. About two stories high.""And... five buildings?""It's all right. I'll pay you properly.""Yodamari-tei free tickets again!? If it's a big building of that size, it'll cost you a lifetime!""Don't worry! I'll pay you in cash this time. I don't think it's a lump sum, but I'll pay you a decent price... Estella.""What!? Why me!"　I pushed her aside, and now Estella is coming in front of me. "No matter how much I do, I can't afford that amount of money!""No, I'll have it done. It's a charity.""The present lord will not be satisfied!""You only have enough ingredients to convince me?""………………Do you have it?"　In an instant, Estella's eyes switch to something serious. 　I like the good thing about that. "I'll explain it step by step."　Get up and sit down on the ground with all the people who were crowding in. 　You should listen calmly. "First of all, this cave is indispensable to make a filtration system, so I'll ask you to give it away. But then Loretta's family won't be able to live properly. So I'll ask her to build a house for me. It's going to cost a lot of money, so I'll be in charge of Estella.""Right now, all the wrinkles are coming to me.""Well, don't be so crisp. If you don't have anything ahead of you, the plan won't go ahead. You're the only one to go ahead.""What a rationale... you have a veto.""Of course, but if you invest upfront, you'll definitely get a good return. That's quite a good return, too.""...like Kasa Jizo?""Oh, yes. That's exactly what it is."　She puffs up her cheeks as if she wasn't convinced, but Estella points her finger at me in unison, urging me to continue the conversation. "It's a little off topic, but securing drinking water alone will not save the 42 wards. Securing drinking water is just an emergency measure. It's just a measure to prevent further casualties.""Certainly... if it rains again, this could happen.""...an annual event."　Jeanette makes the right point and Magda sets out a bad picture of the future. "So I want to propose a fundamental solution."　Everyone's eyes are on me. 　It's like a corporate presentation. It might have been more convincing if it was a power point, but it's OK. "I'll make sewage,""... "Gesui?"　Jeanette bends her head at the unfamiliar words. 　I'll explain it from scratch, so listen. 　In the first place, it is. 　This is what happened because there was no sewage. 　When it rained heavily, water wouldn't flow into the well if there was sewage to let rainwater escape.The accumulation of excrement caused more damage. If the sewage had been properly disposed of, this wouldn't have happened!　So there's sewage!"Sewage is collected in one place through a channel buried underground, dirt is removed using a huge filtration system, and clean water is discharged into the sea beyond the walls."　Although it may not be possible to treat it perfectly like today's Japan, some bacteria can be treated by marine fish. 　Marsha, a marine guild, also said, "If it's just a little bit, I hope the fish will eat it." 　Without accumulating sewage, this kind of disaster would not occur. 　You can also make manholes and flush rainwater into sewage. "If that were to happen... surely the lives of the inhabitants would change dramatically...""Right? Goodbye to the cleanliness of the city and flood damage. Generally speaking, the 42 wards are the lowest and prone to flood damage, but it is the negligence of the lord that no countermeasures have been taken so far.""... that's harsh,""There's a good thing,""What?"　I'll give you a great line to woo Estella, who is beginning to show an interest in sewage. "I'll give all this sewage right to the lord. From now on, I'll transfer all the benefits and authority that I can get from sewage.""Right...?""Oh, when the 42 wards become a model, and the others say, 'Let us have a sewer too,' the lord can negotiate with them with his authority. If things go well, he may have an advantage over the other wards.""...I see. That might be attractive."　This is a pretty big right. It produces a huge profit in the long run. 　He says he's going to make it all go round. "So the lord should take care of the expenses for the works.""Including the construction of this neighborhood,""This city has been hit hard by heavy rain. It's a great deal to sell to other wards.""The filtration mechanism is almost the same as drinking water. We need to make another effort in the final process...""It is possible to conduct a simulated test operation by filtering drinking water.""That's it. First of all, if you build a drinking water filtration system as a charity, and if you look at the results and present sewage, no matter how stupid a lord is, you'd be better off leaving a deer in his place."　If a deer shows a deer cracker, it will shake its head vertically. "You put a very heavy thing on my shoulders,""You've never had a stiff shoulder, have you? Isn't it a good opportunity?""...you feel as stiff as your shoulders without your chest?"　Estella glares at me with a fixed gaze. 　I won't be able to reply soon, but they'll probably pull out the money. 　What's next? "So Umaro,""Okay! If you can get money, I'll take the job! I'll do my best while trying to deceive Mr. Wishart'said Mr. Wishart.　If I could do that, I wish I had done it from the start. 　Well, it's the responsibility of the person in charge to avoid dangerous bridges. 　Estella is in charge this time. You can do the womalo without hesitation. "The person in charge this time is Mr. Jiro. I'll do the Oira without hesitation."　...what?　It's something different from what I thought. "First of all, we'll repair the house we have now and then build a new one. But the key members will make rapid progress with the construction of the filtration system."Ah, that's it, ummallow,""Yes?"　As things stand, umaro only tastes good. 　Naturally, a good story is accompanied by a little pain. "You should set up a branch in the 42nd leg,""Is it a branch?""Oh! We're going to start sewage work now. It's going to be a big project for a few months. It's a waste of time to go back and forth, isn't it?""But if you do that, you'll find a place to live...""That's why you guys are going to make it,""Is it the house that we are going to build now, the house of the Oylas!"　A branch of the Torbeck factory would make it easier to ask for work. 　Transportation costs can be saved, and there are many advantages. "And the oilers do the sewage work?""Oh, I'll leave all my skills to you."　He put his arm around the neck of the woman, whispering in his ear as if to whisper in secret. "When Estella negotiates with each district and calls for sewage are growing, you are the only one with sewage technology. Naturally, the requests will be concentrated at the Torbeck Works.""Well... that's fascinating,""In the end, we may get a request from the royal family of Chuo Ward?""Oh, from the royals to us!"　Womaro laughs half‐heartedly at the vision of a bright future he has yet to see. "However, there is one condition for the provision of technology.""...reward cuts?"　You think I'm only thinking about money. 　...well, it's pretty much the right. "I don't have to be stingy, Estella pays for it.""I can hear you, Jillo,"　I ignore KY's voice from behind. 　Rather than that, we have to win an important contract now. "I want you to employ a large number of Loretta's younger brothers,""What!"　Loretta was the first to react to my words. 　But regardless of that, I will continue negotiations with Umaro. "From now on, construction in the 42 wards will require human resources. It may be useful if there are not enough people. No, they would rather have human resources than any other people.""It is true that five apartment complexes are filled with sewage all over the city... no matter how many people they have, they are not enough.""Furthermore, Loretta's younger brothers are very friendly and easy to use. They're good at memorizing, and most importantly motivated. You've got a lot of experience with some of them, haven't you?""Oh, indeed, they did a good job,""What's more, the mining capacity that created this cave. It's absolutely necessary for sewage work.""...yes, sir,"　Umaro was prejudiced against slums at first. 　However, he is the kind of person who sees the person he actually touches and talks with as a 'person.' 　Under him, my younger brothers can work hard. "Okay. If you get motivated people, and you get technology that no one else has, there's no reason to say no!""Oh, my!"　Loretta exclaims with a loud, fireworks-like noise. 　No matter where I go, I can't get a job, and I can't get a job long enough. 　They must be happy to find employment for their younger brothers because they've been through such hardships. "They're bad brothers, but they're going to work hard. Please train them.""Oh, well, yes! That's a little bit...!"　With her hands clasped and her smile turned at close range, the woman was extremely nervous and frozen. 　The only thing that didn't bother you before was that you forgot because of the excitement of seeing the cave. "I'm glad... that I can make all the younger brothers and the people in town happy."　Jeanette smiles affectionately. 　Yes, we can all be happy. 　If we see people working hard on disaster relief and sewerage, we may lose our prejudice against slums. 　Also, if you become a reliable member of the Torbeck factory, you will surely see a different way of course. 　Then these brothers and sisters will be accepted... and...　Traveling popcorn will boost sales again. 　The profits of Yodamari-tei are huge, haha!　Moreover, I use Estella's money and Umaro's technology and trust to increase sales without running out of money and without doing anything!　Now, you guys!　Work hard, for my benefit!　Well, by the way. 　I wish I could lend you some wisdom to make this town a little more comfortable to live in.
