In the end, the search for the 13th floor was postponed until the following week.

Thor descends to the stone floor, where the temperature is getting colder, and looks again at the passage leading to the darkness.

At the end of the straight path to the north, there should be a large prison separated by iron bars.

When he had fallen from the prison, he had been able to reach it in a day, but the passage through the sarcophagus had taken him more than ten days.

Thor shook his head, wondering which was better.

No matter how much effort and time is spent, if it is safe, it is the right path.

"Okay, let's take our time and check it out."

Thor turns around and looks at the three people behind him.

It was probably colder than he had expected, for Sora and Moe were huddled close together in a tight embrace.

On the other hand, Yuril, who grew up in the north, looks lively and smiles unconcernedly as he watches over them.

"Come on, let's go!"

"Uh, wait a minute. Ah, Moo-chan is so warm!"

The praised child clears his throat slightly in place of a reply.

Moo, completely clad in white fur, is like a natural heater, thanks in part to his higher body temperature.

However, perhaps because he has lived with cats for a long time, he seems to have a habit of unconditionally snuggling up to them when asked to keep them warm.

The search itself went smoothly, despite our indolent start.

"Well, nothing in particular. Nothing in particular... I'm starting to wonder if it's too much..."

The 13th floor was basically the same as the upper floors, although it was 10% larger.

The south side of the building, with its somewhat intricate corridors and the steel dolls that were the guards were placed at strategic points.

The north side is a simple structure with only one large room in which the evil spirits of prisoners and the like are imprisoned.

This floor was more straightforward, with only a long direct passage from the large room to the staircase in the center.

The stairs to the 14th floor were also easily found.

"What do we do now? Mr. Toll."

"How much further to the map? Sola."

"Well, there's only the southeast corner left. But I'm a little curious about this..."

The girl pointed to a line along the south wall.

There is one deliberately protruding point, which stands out because the rest of the wall is neat and clean.

"Doesn't it look strange?

"Yeah, it's pretty obvious on the map."

I didn't notice it when I followed the road along the wall, but when I looked down on it like this, I could tell it was suspicious at a glance.

"This is a good job. Let's check it out right away."

"Heh heh heh."

"Sola-chan, let me see it, let me see it."

The child was handed the map with the drawing board, and after turning it over and turning it on its side for a while, he began to draw on it.

"Ah! What are you doing, Moo-chan?"

Sola hurriedly takes the drawing board away from the child.

But it was already too late, for the map showed a dexterous drawing of a beetle poking its horns into a protruding part of the map.

"Wow, that's pretty good."

"Oh, it's so cute."

"Oh, no."

"No, no, no, you can't doodle on this. You two shouldn't compliment each other either.

"Of course. You can't do that, Moe.

"No, Mr. Mumm."

"No Kuro-suke, huh? Then I'll call To-chan and the others next time!

With such a broken atmosphere, the group headed for the southern wall.

The monsters along the way have already been swept away, so they arrive quickly.

The protruding part of the wall is actually quite large, and seems to be the size of a room.

After a careful examination of the surrounding walls, we found that one of the stones in the corner can be moved.

With his hand on the stone, Thor takes a deep breath.

.

Immediately, a large number of images appear before Thor's eyes at once.

All of them show Thor's next action from his own point of view.

One of the images is of Thor looking toward the wall on the side.

In his vision, he sees a stone wall sinking into the floor.

It seemed that a doorway had appeared.

Next, the view suddenly moved away from the wall, probably because the subject jumped back.

We also see a girl looking anxiously to the left and right, and Yuril lifting his walking stick.

Thor instantly sorts out the images that come toward him like raindrops.

The one in the foreground is the immediate future, and the further back you go, the further into the future it will be.

The event that would occur three seconds later was the swarm of steel dolls that filled the passageway.
