Yang Tianming was surprised because the underground space was too large.

It's even big enough to be his imagination!

At first glance, I can't help but make people wonder that half of the underground of the entire island would probably be hollowed out!

When they left the elevator, they were in a plane similar to a cylindrical shape, with a diameter of about ten meters, extending outwards eight passages, leading to eight different directions.

And below the eight passages is the bottomless abyss.

Each passage leads to an area, and each area is an independent "building".

These so-called buildings are about ten floors high, and their width is terrible. They are thousands of meters long. If you roughly calculate, this building can have at least a few thousand rooms.

Eight passages lead to eight giant buildings.

At first glance, the eight buildings are exactly the same.

There is natural light in this underground space, so I can see clearly, but everyone still can't see the eight buildings, what's the difference.

"This can accommodate tens of thousands of people!" Du Xiaodie was surprised.

Yang Tianming shook his head: "Not stop."

"Hmm?" Du Xiaodie didn't understand.

Yang Tianming said: "What we see now is just horizontal. Have you ever thought about how wide the vertical is?"

Du Xiaodie suddenly realized: "You mean... this building will extend outward?" Yang Tianming nodded: "That is inevitable. Enough width can be used to maximize space utilization, and secondly, these buildings can be used as supporting buildings for underground space, which can be said to be a killing of multiple goals. If I choose,

I would definitely choose this."

All the girls know that as long as it is Yang Tianming's choice, there will definitely be no mistake.

"What about us, where?" Li Yuyao asked.

Eight directions and eight roads all look exactly the same.

"It's here." Yang Tianming pointed his finger in front and asked.

"Why?" Du Xiaodie asked with a curious look on her face, "Tell me quickly."

Yang Tian understood: "If you have anything to say, just go there."

Du Xiaodie was speechless: "It turns out that you were confused too."

The girls quickly followed.

What composite material is this passage made of, like metal or stone? Yang Tianming specially tried the hardness, which is strong enough.

I think these special materials were developed suddenly in the future in the "doomsday".

Although there is an invisible abyss under the passage, the passage is solid and spacious enough that as long as you are not on it, you will definitely not be able to fall down.

But Yang Tianming still dared not take it lightly. Who knows if there is any mechanism here...

Fortunately, I came to the end of the passage and still had nothing to grow.

At the end of the passage is a small flat square, empty and nothing.

Further in, it is the giant building.

Du Xiaodie couldn't help but say, "This doomsday person is really pitiful. He is trapped in such a small place and is suffocated to death."

Yang Tianming sighed: "In the end of the world, it is already a paradise to be able to come to such a place!"

No matter how big this place is, how big can it be? If you have to endure it, you can live in hundreds of thousands and millions of people.

But most people in the world don’t have the chance to come to this place!

This is the reality.

Du Xiaodie also reacted, but shook it

Shaking his head: "Then I don't like this place either, it's too boring."

I don’t know what kind of light source is used in this underground space, but the brightness is still good. Although it is not as bright as the real sunlight, it can be seen clearly like cloudy days, but it gives people a sense of depression and heaviness. "Don’t look down on this place, I don’t know how much effort we can put in before." Yang Tianming looked up at all this and said, "For example, this underground light source, water source, oxygen, food, ventilation, sewage discharge... all kinds of things

All kinds of problems are more complicated than we can think of, and we should be in awe."

"Oh." Du Xiaodie nodded honestly.

"Let's go in and take a look." Yang Tianming said, pointing to the building in front.

The building is large enough, with more than a dozen entrances on the ground, just like the unit doors in ordinary communities, but it is larger than the unit doors and more like the gates of a hotel.

Yang Tianming walked in casually, walked around, went upstairs, and went into rooms to check. It was found that this building was indeed a residential building and was for people to live in.

The vertical width of the building is indeed not as simple as the surface. Walking straight into the corridor, it is at least 200 meters, just like apartment buildings lined up side by side.

Roughly calculated, this building can accommodate almost 100,000 people!

There are too many rooms, tens of thousands of rooms, and they can't finish watching them all.

Although everyone was curious about the past doomsday and wanted to know what was born here, after looking at several rooms in a row, no one planned to continue watching.

Because they all found some strange problems.

First, they naturally did not show a living person in the entire building.

But a dead man and a single bone did not appear!

Secondly, every room is clean, without any daily necessities or any garbage, and it looks like no one has ever lived in it.

But they found traces of their lives in these rooms again.

For example, some walls are left with graffiti, painted flowers, little white rabbits... and even some people's messages!

"Bye now……"

"I really don't want to leave!"

"Will anyone really see it?"

...

Any "message" that can be understood is written concisely, as if time is urgent and there is no time to write more.

It's more like I don't know what else to write.

Some "messages" are completely doodles, and they look like people in a bored mood, drawing a bunch of messy lines in a messy situation.

In short, people must have lived in these rooms, but I don’t know what they had given birth to, so all of them left later.

Yang Tianming and his friends have looked for different floors and rooms, and they all saw roughly the same.

Finally, when everyone walked out of the building and gathered in that small square, everyone had the same problem in their hearts.

Where have they all gone?

All the girls looked at Yang Tianming.

And this time, even Yang Tianming had no answer.

"Go to other buildings to have a look." Yang Tianming said.

Immediately afterwards, he took the girls to the rest of the others, one by one, and spent several hours reading roughly all the eight areas...

Finally, everyone was silent again!

They have shown different functions in each area and have a more intuitive understanding of this underground building, but the problem is getting deeper and deeper. Because they are still alone and have not seen a single bone...
