Three days later.
　I went to the Adventurer's Guild and checked the emergency request.
　........However, the emergency request for the underground water system was still the same.

　I go to the receptionist with that request.
　It's a different receptionist than before.

　The receptionist looked at the request form I brought and looked at me in surprise.

"Yo, are you sure?
Yes, sir.

　I wondered if it was something I would bother to check.
　Then the receptionist glanced at my clothes.

"Yes, sir.

　I'm only wearing simple equipment, including a leather breastplate.
　So I guess that's why they deemed me a novice adventurer.

　I can fight reasonably well, but as a novice adventurer, I'm not wrong.

'You will be held until you are completed, is that alright?
Yes, I'm fine.

　I've only been on the late shift the last few days.
　The request would be for a 9am to 5pm hold.

　My late shift is from 6pm to 11pm.
　So, no problem.

'Well then, I'll need to see your guild card.
Yes, sir.

　He hands the guild card he took out to the receptionist.
　The receptionist holds it out to a fairy sitting nearby.

　When the fairy touches the guild card, a request is written on it.

Your request has now been received. The bloodmouths that are targeted to be defeated this time are not strong monsters, but don't be alarmed. If it becomes dangerous, it will counterattack unexpectedly.
I know, sir.

　The fairy holds up the guild card with both hands.
　Tapping it, she walks over to me and hands it to me.

　My adventurer rank is currently F-rated.
　There are many requests that can only be accepted if you raise your adventurer rank.

　If you want to be a top-notch adventurer, you need to keep up with the requests.
　You need to accumulate points to get your adventurer rank.

　There is a number 0/100 next to the word F rank on your guild card.
　When you complete a request, you'll get the points allocated for each request.

　The point earned for this request is 10.
　When I looked at it before, it was 5, but I guess that's because there were not too many people taking the request.

　On top of the number 5, the number 10 is written down as if it were written over and over.
　The increase or decrease of points to the guild card will be managed by the fairy.

　Also, if you fail a request, the points to be increased will be subtracted.
　If you fail a request in succession, the guild will decide that you are not worthy of that rank, and will drop one rank.

　Up to D rank, adventurers can receive points for requests of other ranks.
　If a D-rank adventurer completes an F-rank request, he or she will still get points.
　However, the points will be much less than they should be.

　From C rank, you have to complete requests of the same rank or higher to get the points.
　Also, in order to be promoted to the B, A, and S ranks, you need to take an exam at the guild headquarters.

　Therefore, adventurers with a B rank or higher are that valuable.
　It is also the reason why many people languish at C rank.　

　There is no harm in raising your adventurer rank.
　The requests you can receive will change with each rank, and the rewards will increase.
　If you want to live a wealthy adventurer's life, you should at least get C-ranked.

　If possible, you should aim for a B rank.
　I go to my client, the management office that manages the underground water system.
　When I told the receptionist at the control center, I presented my guild card and explained my situation.

　He is a friendly man.

I'm glad to hear that. It was not easy for the staff to deal with the situation alone. I'm glad to hear that you are willing to work alone.
It's so much a part of our lives.
'Great for a young man!　You will work with the sisters that the church has sent to do the cleansing. I will introduce you to that person and you will follow me.
I understand.

　I walked up the stairs with him.
　We went upstairs to a corridor and entered a room.

"Here's Sister Linial. He's a bit of a peculiar boy, but he's a real hand at purification. Now, let's get to work together. Now, if you'll excuse me, I have some business to attend to. You'll have to hear the details from Linial.

　He was busy and he left.
　........almost everything was thrown at him, but is this the way it is?

　This is the first time I've ever received a request from someone, so I don't know what to expect.
　For now, let's hear from Linial-san.

　When I knocked on the door, I felt the presence of a person approaching.

''An........adventurer?''

　Her pale green hair swayed as she tilted her head. Her hair was long, almost reaching to her waist.
　Seeing that she was dressed in a monastic uniform, she was definitely the Linial in charge of purification.

　There doesn't seem to be anyone else in the room.
　She turned her slightly languid eyes to me.

''Yes, sir. My name is Lelius, the one who received the Bloodmouth hunt this time. It's nice to meet you.
Lelius it's nice to meet you. I'm Linial.
You must be Linial, nice to meet you.

　With a calm voice, Mr. Linial said.

'....Come inside, come in. I'll explain the situation briefly, just in case.
I understand.

　Along with Mr. Linial, I walked into the room.
　On the table in the room was a sheet of material.

　Is it a map of the underground utilities?　The blacksmith's ability to check and confirm it was confirmed.

'The cleansing we do once a month, what is it... we've managed to finish this area now.

　With that, Mr. Linial circled the map of the underground water system.
　

''I was doing it while taking down Bloodmouth, but it's hard when I'm on my own.
'The staff are helping you, aren't they?
Yeah. But he can't devote much time to it because he has other duties. I've asked the church for help, but they're short on people too.
"...I see. So you got a request for an adventurer.
"...Yeah. One, but I'm glad to have an extra person. It's going to make things a little easier.

　Huh, and even so, Linial-san let out a breath that seemed to be very hard to take.

''For now I'm going to cleanse this compartment next. I'm going to set a trap, and after about an hour or so, I'll go check the trap. We'll repeat the process and take it down.
I understand.
There are only five traps in all. I've already set them up and we'll go look at them together.
Yes, sir.

　I get a map from Ms. Linial.
　I walked with her from the administration office to the underground waterworks.
