After the conversation, Takase headed for the sixth layer. Now that I knew the winner of the competition, I decided to return to the ground level. The shortcut is to go from the transfer room to the first floor and back to the ground.

　I go back the way I came. This is where Metis' mapping ability comes in handy. She never forgets the path she has taken and can create a map based on it.

Is the map information you got at the Bastet statue only for the first ten layers?"

God is stingier than I thought. It would have been easier if he had generously given us the map information for the entire Jukai dungeon."

　Metis guided me back to the transporter room, and I returned to the first layer by the transporter gate. When I went out of the transfer room, I found a small waterfall. I dove under the waterfall and went outside.

　There was one layer of mountains that looked familiar. If that mountain is there, the stairs back to the ground are nearby. We went up to the stairs and returned to the ground. We went to the Adventurers' Guild, which manages the Sea of Trees dungeon, and asked to meet with the branch chief.

　I was to meet with the branch manager, and when I went to the branch manager's office, Branch Manager Nozaki was waiting for me.

'I've heard rumors. You are Dr. Grimm, aren't you? If you wanted to report it, there was no need to rush."

　She was a female branch manager, probably in her late forties.

No, I just wanted to report that I had activated a trap in the fourth level of the Sea of Trees dungeon.

　Branch Manager Nozaki's face turns stern.

Is it a life-threatening trap ......?"

In a way it was. It was a transporter trap."

That's dangerous. Where was the trap?"

Elmore and I encountered and defeated a subspecies of dragonet in the fourth level of the underground passageway, and a treasure chest came out of it. That treasure chest contained a trap."

Who's Mr. Elmore?"

Shadow Puppets."

　I pulled an Elmore out of the shadows. Seeing this, the Nozaki branch manager rolls his eyes.

I'm sorry. Did I startle you?"

Unauthorized duplication: this narrative has been taken without consent. Report sightings.

　I usually take shadow puppets in and out as a matter of course, so I didn't tell them beforehand.

No problem. By the way, when you say you activated a transporter trap, where were you sent?"

Elmore and I were sent to an abandoned area on the thirteenth layer.

　I told him specifically what happened when the trap was activated. Branch Chief Nozaki tilted his head.

That's funny," he said. You were sent to the thirteenth layer. Are you saying you've come back already?"

The coin that triggered the trap was a transfer gate key.

"Don't tell me there's a transfer gate in the Sea of Trees dungeon?"

　I took out the coin for the transfer gate key and showed it to him.

I'm sorry. Let me look into it a little."

　The Nozaki Branch Manager invokes "Item Analyze" on the coin. He must have understood the result. The branch manager nodded as if he was satisfied.

'I see, it is indeed a transfer gate key. Could you tell me what you did from the thirteenth layer?"

　I told them that I had defeated the Blue Ogre zombie in the city of ruins on the thirteenth level and went up to the grassland area on the twelfth level. Then I explain that I defeated a Queen Spider that seemed to have no lodgings, found a staircase, and went up to the desert area on the first level.

You have done a wonderful job. You told me that the tenth level is a desert, what kind of demons did you encounter?"

The demons were killer ostriches and blue-silver golems. But I didn't care about those demons. What did surprise me a little was that there was a small pyramid."

　The pyramid itself was not hidden because it was something that could be easily found if one looked for it.

Did you find anything in that pyramid?"

There was a statue of the god Bastet. So something kind of strange happened there, and I got some map information on the tenth level."

　The Nozaki branch manager asked him to tell us specifically what he meant by mysterious things, but he did not.

I understand. So it's related to something that would benefit you as an adventurer?"

Well, that's what I mean."

　When you go up to the tenth level and say you defeated the mid-boss in the mid-boss room, they ask you what kind of demon it was.

It was the demon prince Amaimon. He was a demon whose magic didn't work, but I worked with Elmore to defeat him, and we came back to the first layer via the fifth layer from the transfer room on the tenth layer.

Could you provide map information along the way?"

　I agreed. By providing them, they would be recorded as my achievements.

However, please keep secret from the other adventurers that I am the owner of the transfer gate key and that I am the one who was caught in the transfer trap.

'I don't think you need to hide it, but okay.'

　We decided that it would be better to provide information about the transporter traps, as there may be others. If other adventurers were unknowingly caught in a trap, it would be a matter of life and death.

　After I finished my report, I returned to Shibupaper City and called Alisa and the others. Arisa and the others gathered in the mansion, and they wanted to know why I suddenly had them assemble.

"Actually, I was on an expedition, and in a dungeon there I got something called 'limit breaking fruit.'

　Chika and Yukari's eyes lit up when I explained about the "Limit Breakthrough Fruit. Both of them had reached the limit of the magic level of life magic.

　When I told Chika and Yukari that I would give them the "limit-breaking fruit," they looked at each other.

But wouldn't it be better if the teacher used it?"

　Chika said.

Unfortunately, this fruit expires in three days. None of my magic levels have reached their limit, so I can't use them."

If so, we'll buy it."

　Chika and Yukari said they would pay the price. Their willingness seemed firm, so I agreed. However, I did not know the market price. When I asked Métis, she told me that there was a record of a sale for about 10 million yen in the past.

Seems cheap to me."

　Alisa tilts her head.

It's the same reason why food that is about to expire is cheaper.

　Some adventurers might be willing to pay 100 million yen for it, but it would be difficult to find and sell it within two days. Besides, I only wanted to give it to someone whose identity I could be sure of.

　I ended up selling it to Yukari and Chika for 10 million yen. I gave them the "Limit Breakthrough Fruit. Chika ate the fruit first. She said it tasted like a peach.

　Immediately after eating, Chika's body temperature rose and she seemed to be in pain, but after about five minutes, her temperature returned to normal. When Alisa checked Chika's talents, she found that her life magic talent had changed from "C" to "C+".

　When Yukari learned of the result, she ate the "Limit Breaking Fruit" and changed her life magic talent from "D" to "D+".
