The iron door looked very heavy, I pushed it with all my might, but after pushing it, I realized that it was not as heavy as I thought, and it didn't take much effort for the door to open. Pen % fun % Pavilion www.biquge.info

Behind the door was a long passage, and it was pitch black in the depths, and I didn't know how long it was, let alone where it led. The floor of the passage was covered with a thick layer of dust, and the traces of the previous vanishing ones reappeared, because the rows of footprints on the ground were very clear.

The footprints are all concentrated in the middle of the passage.

After a little observation, I realized that they were indeed four people!

I was prepared for this, so I wasn't surprised and continued to check my surroundings.

The whole passage is all made of cement pouring, very regular, about four meters high, about five meters wide, two side walls are a slip of explosion-proof lights, about ten meters apart.

It's a lot like the legendary bomb shelter, I've never seen anything like it, and I've only heard of it before.

But what exactly did the Japanese build such a large underground structure here?

Because this passage is completely easy for a large truck to pass through.

Could it be that they're going to take something from here? Or is it some other reason?

Looking back at the iron door behind him, he found that there were four huge iron hooks and a pair of locks on this side of the iron door. The door lock has long been rusted and unlocked.

Looking at the deep passage, I hesitated for a moment, and then continued to walk inside.

About a hundred meters later, the passage began to turn, no bypass was found, the radius of the turn was at least twenty meters, it seems that this passage is really for trucks, unless they adapt to local conditions, there is really no other explanation for building such a large curved curve!

After walking another 200 meters, a lot of small doors began to appear on both sides of the passage, which should be storage or rest rooms, and the distribution is also very regular, more than ten meters into one room.

In order to prevent omissions, I began to check room by room.

I looked at several rooms, but I didn't find anything, most of them were empty, until I saw the eleventh room.

This room was noticeably larger than the previous ones, and contained a damaged iron-framed bed, three wooden tables, two of which were broken and had fallen to the floor. Only one is good, but one leg is also slanted.

On the ground in front of the intact table was a broken lamp and a disintegrated microscope, and behind the desk was a wooden chair, which had also been dismembered. It's like something has happened here before, and who's so boring to be angry with this stuff?

It feels like a place to work and live.

I have the impression that if this is really an underground fortress, there are usually only two types of people in this kind of place for the Japanese: battlefield commanders and researchers.

Judging by the items left in the room, it looks like a place used by scientific researchers.

The room is very dusty and no one has been in this room for a long time!

Judging by the footprints on the ground, it seems that the four people who had passed by here before did not intend to enter these rooms to search.

It made me wonder what these people were here for, no one was going to be bored enough to come to this place to play, they must have come here for some purpose.

Even if it's playing or exploring, for such an amazing underground structure, at least you will know the surrounding situation first.

Usually, the first thing we think of when we enter an unfamiliar environment is to find out, but it is clear that the previous four people had no intention of checking the environment at all.

If this is the case, there are only two possibilities: one is that these people have a specific purpose, this place has no meaning to them, and they are only passing through here, so there is no need to care about something that has nothing to do with the purpose!

The second is that these people know a lot about this place, or rather, they have been here before, they know everything about it, and the purpose of their trip has nothing to do with it, so there is no need to care about anything.

However, the first possibility should be unlikely.

Because, even if the task is special, if it is a newcomer, there is still a minimum sense of freshness, such as walking to the door of a certain room and looking inside. However, all the footprints were always kept in the middle of the passage along the way, and there were no paused footprints in front of the door of any room.

This shows that these people should know everything here very well, otherwise this would not be possible.

So, who are these four people, how do they know so much about the situation here, and what are they here for?

I used to hear that the little devils have a lot of biological research institutes in the Northeast, to put it bluntly, it is a place similar to Unit 731 that specializes in the development of chemical weapons, and most of them are underground, so it is generally difficult to be found.

After the end of World War II, a number of such sites have been discovered incessantly.

There is such a room here all of a sudden, could it be that this is also a research site for bacteriological weapons?

Dog-sun-you, do you still deserve to live on this earth?

No, if it is, it's another big incriminating evidence of those brutes, and we need to take a good look.

Thinking of this, I walked in.

When I walked to the table, I found that there was also a magnifying glass without a lens on the table, and the lenses were right next to it, which had been shattered and scattered all over the table, and although they were covered in dust, I could still see it clearly at a glance.

Since this is where the researchers live, there should be a lot of information here, but when I look around, I can't find even a small scrap of paper.

It seems that these little devils should have been in a bit of a hurry when they left, maybe the owner of this room was forcibly taken away, otherwise the scene would not be so messy.

But why didn't even the scraps of paper remain?

In this case, there is only one possibility - the information is very important, or very confidential!

So, what exactly was the owner of this room working on back then?

Thinking of this, he casually picked up the magnifying glass on the table, which had no lenses, and wiped the dust on it with his sleeves, but suddenly found that there were a few small words engraved on the handle of the magnifying glass.

I hurriedly held it up in front of my eyes, only to see that it was engraved with the four characters "Torii Ryuzo", I also know a little about Japanese, these words can still be recognized, moreover, this is basically not much different from Chinese, if it is written in Chinese, it is "Torii Ryuzo"!

When I saw it clearly, I was immediately shocked, wasn't Torii Ryuzo one of the discoverers of the Red Mountain culture back then? Could this be the place where he once stayed?
