Months before the world tree grew in Harte's house...

　The drainage pipe for the bath in the mansion is broken.

　Normally, the water from the bath goes through the septic tank and then is released into a river that flows nearby as sewage.

　However, when the pipe was broken, the water that flowed out of it went somewhere else.

　Tina, who has been put in charge of the mansion, went to the basement of the mansion to investigate the effects.


　In the basement of Hurt's mansion, there is a warehouse where foodstuffs and other items are stored.

　The water that flowed out of the bath had not come to that stockpile warehouse.

''........For now, the foodstuffs are safe, right?''

　After confirming that the foodstuffs were safe, Tina then opened the door to the stockpile warehouse and descended the stairs that were beyond it to head further underground.


　A vast space exists further below the stockpile warehouse in the basement of Hurt's mansion.

　This is the space that Tina created with earth magic for Hurt to train his magic.

　Tina is that someone has been reincarnated in Hurt's body. And she realizes that he is training in magic behind Tina's back.

　There was a secret that she couldn't even tell herself - and Tina was willing to wait patiently until Hurt was ready to tell her that secret.

　She hoped that Hurt was a brave man of protection. She had hoped.

　But that, she was afraid to check it out.


　She had waited for him(...) for a hundred years.
　So there's no need to be in a hurry now.

　He must have just been reincarnated and his memory is not stable. He should be able to remember himself for some reason - that's what he decided to think.


　So Tina created this space underneath his mansion so that he could secretly train in magic after he entered the magic academy.

　Of course, the walls and ceiling are covered with multiple layers of defensive magic to prevent him from being buried alive no matter what magic he uses.

　It's a very sturdy underground space created by the world's strongest level 250 magician, even though there are no shifting heroes now.


　However, in the end, this space was never used by Hurt once.

　This is because of the fact that Hurt used all his magic in his first class after entering the magic academy.

　With a(-)le, Tina realized that Halt had no intention of sneaking in magical training anymore.

　─ Or maybe he had the intention of secretly training magic.

　Even if that was the case, Tina could no longer let Hurt use this space.

　It's a very good idea to have a good idea of what you're looking for.

　For his safety, Tina did not tell Hurt about this space.


　─ ─ ─ ──***──.

　Tina also carefully waterproofed the space because any leaks or inflow of groundwater could submerge the underground space.

　Therefore, normal rainwater and groundwater did not invade this underground space.

　However, the water that drained from the Elnor family's bath was not just water.

　It was water that May, who had the power of a Spirit King class, had warmed using primordial fire.

　When Seira, who possessed the power of a saint, entered it, the water was given the effect of holy water.

　When the body fluids of nine-tailed foxes, dragons, and even the Demon King are mixed in, the water is transformed into a hot water that can store an enormous amount of magical power.

　This hot water would recover all of the magic power if a person lacking it entered the hot water, but if a person with extra magic power entered the hot water, it would become something that could store as much magic power as possible.

　If Hurt, who has an infinite amount of magical power due to the influence of the evil gods fixing his status, enters such a hot water...

　A kind of amazing hot water that could heal any injury, extend one's life, and contain an enormous amount of magical power - Sugoyu - was completed.

　It was no exaggeration to say that this Sugoyu was one of the best items in the world. The Elnor family would pour this hot water into the sewage system the next morning.

　However, when the drainage pipe for the bath broke, the hot water went into the underground space that Tina had created.

　The hot water was slowly eroding the waterproofed underground space caused by Tina's earth magic.

　As a result...


Is this an orichalcon?　This is adamantite. And this is adamantite and magical ore.........

　The wall in front of Tina glowed the same color as the ring she wears on the ring finger of her left hand.

　The baboon kane, an immutable metal.
　It's an ultra-rare ore. The part of the wall where it could be seen alone was several dozen kilometers long.


　The underground space that she had created had been eroded by the awesome hot water, and all of its walls had been transformed into a wide variety of rare ores.

　If the rare ores in this space could be mined, it would be possible to produce any kind of armor.

　Tina's H&T Chamber of Commerce also owns several mines, but the combined amount of mining from all of them is less than half of the amount that is here.

　In particular, not only do they not own any mines from which baboon kane could be extracted, they had never even heard of their existence.

　Moreover, all the ore in this underground space was bare. I had never heard of such a thing, let alone own a mine.

　The place where the leftover water from the bath washed ashore was a space where you could collect all the treasures you wanted.


　─ ─ ──＊＊＊＊──.

　Time moves forward, today.

　Suddenly, a huge tree appeared in the courtyard of the mansion.

"It's not possible...

　Tina was overwhelmed by the huge tree's presence, and after letting go for a bit, she noticed something and hurried to the underground space.

　The underground space she had created was located directly below the courtyard.


''Ah, I knew it was going to be like this...''

　I had a bad feeling about it.

　The premonition had come true, and the roots of the giant tree in the courtyard had encroached on the underground space.

　The giant tree had taken root in the rare mine and sucked out its magical power.


　Most of the rare ores, such as demonic ore and orichalcone, had been turned back to just stone.
