Half an hour later, all of them received a message that said, "The safe zone is refreshing... ”

Finally, after a whole half day and 12 hours of waiting. A blue circle begins to appear at the outermost part of the map, slowly shrinking towards the white circle.

If there are still those outside the white circle, they must also act, otherwise what awaits them is a painful current.

A few hours had passed since Chu Que fell asleep, and within a few hours, the number of survivors had dropped to 40.

It took less than a single digit to die overnight, but just a few hours after dawn, nearly 15 people had already dropped.

It's 10:11 a.m., and Junyu is looking at a book with Erlang's legs crossed, taking advantage of the light coming in from the window.

The book he found downstairs was not in Chinese, but in French. As for how Jun Yu learned French, of course, his father taught him in Hawaii.

The book, as the name suggests, is a novel, called 'Del Rorschach Nights'. In fact, there is a preface at the beginning, which is an autobiographical essay of a personal nature.

Yu Chi Junyu looked at it briefly, and there were some unbelievable secrets about this island.

But in Junyu's opinion, a lot of what is written in this book is nonsense, so I read it as a novel.

It is written in the book that under this island, there is a huge underground passage that connects the entire island. Within these passages, a wide variety of spaces were built, including residential, recreational, military, and so on.

These are not big problems, according to Wei Chi Junyu's knowledge, in reality, most countries will also build such underground facilities, but more or less different.

The problem appears later in the book, where it is written that the protagonist called 'Fica Seros' is actually referring to the author himself.

He searched there alone in the underground passages. As previously mentioned, a large amount of canned food was found in the underground passages, which could be stored for at least a few decades without spoiling.

There are also a large number of munitions, all of which are of the newly produced kind, and the sealing oil is applied to each gun.

Ficcarols came to a space, a space that uses underground water to generate electricity, presumably this hydroelectric power to maintain the lighting and other equipment in the passage.

Deeper and deeper, I saw a seal on a door that looked shabby, which said, 'Do not open'. The notes are already a little damaged, I don't know how many years ago they were posted.

Ficaselos was a 14-year-old boy with a curiosity about the unknown.

If it weren't for that, he wouldn't have been so bold as to go alone into the empty underground passage.

In the darkness, a voice seemed to call out to him from behind the door, "Theros... Theros, hurry up~come here~" The voice felt far away, but it seemed to be ringing in his ears, and this voice couldn't distinguish between men and women, because it felt like a child's voice.

Theros approached the door step by step. It's a very ordinary mechanical door (I don't know what to call it) with a wheel on it, and when you turn it, it should be able to open.

At first, Theros was very careful, and walked to the door and tore off the seal. Then put your ear close to the door to hear if there was any sound inside.

After listening for a while, he didn't hear anything, and stopped at the door to think for a while. In the end, driven by curiosity, he turned the roulette wheel vigorously with his weakened arm.

The wheel creaked as it turned, and then the sound of the gears turning from inside the gate was heard.

There was a click, and finally the door was gently flicked open, revealing a small slit. Theros strained himself and pulled the roulette wheel hard to pull the door open.

It wasn't pitch black inside, but there was still waiting for the lights to illuminate. But the taste inside was very strange, and Theros didn't know what to call it, and he didn't like it very much.

Looking inside from the outside, there was some unknown black solid on the ground. Theros walked through the door and looked inside, followed by a spiral staircase, which was probably the place that led to the depths.

Theros thinks that the reason for the closure of this place may be whether it will cause something like the sinking of the island if construction continues here. I have to say that boys at that age always like to be whimsical, and their thinking is extremely active.

Holding on to the wall, I walked down step by step. The further down you go, the more and more black solids appear on the ground, even on the walls. Theros didn't know what they were, and thought they were familiar, but he hadn't seen them before.

Then he heard the sound of some mechanical motors, and Theros wondered, could there be a lot of machinery down there in such a place? It's obviously sealed, but why is there something?

In order to clear up his doubts, Theros decided to continue and find out.

I don't know how long I've been walking, I don't know how many steps I've walked. In short, what appeared at the bottom was another door. It was a simple iron gate with a small closed window above it, which looked like a prison.

Theros wrinkled his nose and smelled a strange smell, a little different from the previous one, but even worse.

But a boy's determination would not be defeated by the unpleasant smell, and he decided to push open the iron door to see what was inside.

I wonder what the smell is coming from inside, and what kind of machine is making such a sound inside.

Just as he was about to push the door, another strange sound came from inside. Theros was an adventurous boy and spends his time exploring the island, seeing wild boars, squirrels, and hateful voles.

The voices coming from inside the door were a bit like these ignorant people who could only run around for their own survival every day, looking for food. Theros thinks that this is probably the reason why humans can be called human. Humans have genes that are more intelligent and adventurous than these animals.

Thinking of this, Ficcaselos couldn't help but smile, after this expedition, he must surprise those friends. I've been to a field they've never set foot in, a field of their own.
