I examined the spear I obtained after defeating the dragonute subspecies with the appraisal monocle. It was labeled "Zekkai Yari," which is said to be the spear of Bishamonten. The Zekkai Yari is a weapon said to be the spear of Bishamonten.

　It is a legendary-class spear and a more prestigious weapon than the high king-class Trishula . However, we would not know how to use it unless we investigated. I handed the Zekkai spear to Elmore.

May I use it?"

I don't care, because it will make us stronger as a team. Let's go check the treasure chest.

　I approached the treasure chest. I checked it out, but it didn't look like a trap.

I'll open it.

　Elmore puts his spear away in the storage ring inside his body and approaches the treasure chest and places his hand on it. I take a few steps back and watch. Elmore carefully opens the lid of the treasure chest. Elmore looks inside and sees a book.

What happened?

It's a book, but it doesn't seem to be a grimoire. But it doesn't seem to be a grimoire.

　I checked for myself. It certainly did not look like a grimoire. It was written in secret script as "The Book of Memory: Concepts".

　When I took it out and looked inside, I found that it appeared to be a decorative manuscript. Like an old Bible, it was made by a craftsman one by one, and seemed to be made of leather paper instead of ordinary paper.

This book is called "The Book of Memory: Concepts."

What does it say?"

It is said to be about memories constructed by God."

What do you mean?"

I don't know, I've only read the first part."

　Which god are we talking about?　Is it one of the mythological or legendary level magical weapons that appear to have been used by a god?

　Or is there such a thing as a dungeon god?　Metis doesn't seem to know either, so we'll just have to read this "Book of Memory: Concepts" to find out.

　When I put the "Book of Memory, Conceptual Edition" away in the storage armoire, I noticed that there was one more thing left in the treasure chest. It was a small coin. On that coin was the image of a person with a fox's face.

Stolen from its rightful author, this tale is not meant to be on Amazon; report any sightings.

　I picked up the coin and went to check the reverse side. At that moment, something like iron grating comes down and closes at the exit of the room, and a strange pattern of light appears around the treasure chest.

'Run away. It's a transfer trap.'

　Elmore jumped into my shadow. He thought to himself, "I'm not going to fall apart.

　I grabbed the sacred sword Gram and tried to run to the bars. I thought I would cut through the bars with my sword, Gram, and escape.

　But the moment I swung the sacred sword Gram, the transfer began. My eyes went black, I felt as if I were falling, and then I was slammed into the hard ground.

Ugh, I hit my hip.

　Looking around, it appears to be a domed room. I looked for an exit and found it directly behind me and went out through it. What I saw there was a city in ruins.

　Metis brings Elmore out of the shadows.

How many layers are we talking about here?"

I don't know."

　I think it is below the fifth level, because there must have been no ruined city between the first and fifth levels. Looking around, one can see that most of the buildings in this city are long and narrow, tower-like structures.

　Those buildings are broken in the middle or have collapsed walls.

'This is a city of the undead.

　I take out the light sword Clau Solas and hang it on the sword belt. This sword belt was custom-made so that I could hang the light sword Clau Solas, which is thicker than an ordinary sword.

I don't have a choice. Let's find the stairs and go up."

'I hope it's not a deep hierarchy.'

　Not at all. We turned right onto what appeared to be a main street. The first demon we encountered was, as expected, an undead skeleton knight.

　Elmore dispelled the skeleton knight's spear with his Zekkai spear, turned and slammed the spearhead into the skull. With that blow, the skull is crushed and the skeleton knight falls. It seems that the Zekkai spear has some kind of power that is effective against the undead.

　Immediately after the skeleton knight fell, the undead crawled out from all over the city and came at us.

　First, five wraiths attacked at the same time. When Elmore thrusts his Zekkai spear into the wraiths, they scream and disappear. As expected of Bishamonten's spear, it seems to work on the wraiths as well.

　I pulled out my light sword, Clau Solas, and slashed at the wraith. The two sword blades cut through the wraith and disappear without time to scream.

　Skeleton and ghoulish demons were killed with a single blow. The Blue Ogre zombies were a little tougher, but they were faster than the other undead, so it was not possible to kill them with a single blow.

　We escaped from the city, running off the undead. Then we continued straight ahead. Luckily, we soon found a staircase. It was a stairway to the top.

"Thank God. If this had been a staircase going down, we would have had to turn around and go to the other side of town."

　When we went up to the upper level, it was a vast grassy field. We took a hover vehicle and flew to the other side of the area.

　On the way, we encountered a swarm of mega-ants. They were large ants, about 70 centimeters long, but their number was a problem. They formed a swarm of about 300 ants.

　I raise the altitude of my hover vehicle to the limit of five meters and pass through.

That herd needs a magic like 'Flare Burst,' an offensive magic."

It's best not to fight," he said. I don't want to fight unless I have some treasure. Judging from the demons we've encountered, how high up do you think we are?"

I don't think it's a very deep hierarchy. I don't think it's that deep. I think it's 12 or 13 layers at the deepest.

　Then, after going up about eight layers, we would be at the fifth layer, which is our destination. It seemed that I had dropped out of the race to obtain the fruit of my talent. I look disappointed.

'Speaking of which, what was that coin you were talking about?'

　At Métis's question, I took out a coin. I had not yet examined it. When I looked it up in the appraisal monocle, it showed "Transfer Gate Key.

"Oh, no.

What's wrong?"

This guy was a transfer gate key. That means there are transfer rooms in the dungeons of the Sea of Trees.

　There may be a transfer room on the fifth tier. However, I don't think we could be the first to go to the fifth layer. However, it was likely that we could be the first to get to the fifth layer from next year onward. We could find a transfer room on the first floor and move to the fifth floor from there.

　Flying across the meadow with a bright face, I spotted a queen spider ahead of me. It was a ridiculously large spider, about 15 meters long.

"We think it's a no-show."

　I thought that would be the case. Queen Spiders are known as demons that are encountered after the 20th level in advanced dungeons. It is hard to believe that this place is below the 20th level.
