"You go to the southwest corner and see if there are any holes in the ground?" Fei Yunfan didn't answer Oscar, but just told him to do things.

Oscar looked puzzled, walked to the southwest corner of the house, and sure enough, a small hole the thickness of chopsticks was issued, the small hole was on a rectangular green brick, the green brick was very well camouflaged, at first glance I thought that the brick was broken, and shouted: "Brother, there is indeed a small hole here." ”

The corners of Fei Yunfan's mouth rose slightly, and he said, "You go and see if there is a small hole at the door?" ”

"Yes."

Fei Yunfan used his foot to pry open the hay bed laid by Wang Xiaoer, which also had a small hole.

"That's right, it's all right, trapped dragon lock, Oscar, you stand in that position, Guan Siyu, you stand in the southwest corner, I'll count one, two, three, everyone press together, a chain will come out of the small hole, and then everyone pulls together."

"One, two, three."

The three of them pressed the green bricks, and the sound of the chain dragging came out of the ground, and a dark and slender iron chain stretched out from the small hole, and the three grabbed the iron chain, and then counted "one, two, three", and pulled the iron chain out together.

"Dangdangdang" three sounds, in the middle of the house, one by one collapsed, there was a square hole more than one meter long, the square hole vertically downward, a soft ladder hung on the wall of the square hole, the black hole inside, it seems to be quite deep.

Fei Yunfan went down the soft ladder, didn't go down a few steps, a familiar smell of rotting corpses came from the cold and dark bottom of the cave, Fei Yunfan held his breath, tore off a piece of cloth from his clothes, and covered his nose and mouth, the cave wall was inlaid with green bricks, the cave wall was very damp, and there were water droplets hanging on the green bricks.

Finally down to the bottom, the hole below is very wide, but it is not an artificially dug cave, as if in a small lake stalactite cave in general, the moisture under the hole is more serious, the water droplets condense into water droplets, dripping on the ground, "Ding Dong Ding Dong", the hole is full of such echoes, like the saliva dripping from a man-eating monster, making people feel creepy in this darkness.

Oscar and Guan Siyu came down one after another, although the cave was a natural cave, the ground seemed to have been rebuilt, and it was also paved with green bricks, and there were stairs one by one, the stairs zigzagged downward, and they continued to walk down the stairs, and soon came to the first turn, and then a long staircase.

Fei Yunfan didn't know how deep this hole was, he only remembered that he had turned four such corners, and he was also sketching the structure of this hole in his heart, as if it was stacked up one by one Z-shaped steps, so aimlessly going down, didn't he really want to go to the center of the earth?

"It's hot." Oscar said as he unzipped his coat.

Fei Yunfan also felt it, logically speaking, the further you go underground, the lower the temperature should be, how can it feel hotter and hotter.

Fei Yunfan stopped suddenly, there was a light bulb in front of him, and it was still on, and the three of them looked at each other, how could it not be strange that there was such a modern thing in this underground.

Even if there is a light here, where does the electricity come from, is there still someone in this cave, using electricity from generators? This is really unheard of, in an abandoned military station, an old village found a deep hole in the ground, there is a light bulb in the hole that is still on, if it is a coffin, it is not so surprising.

"Brother, in the past?" Oscar's voice has changed a little, I haven't seen him like this in Xiaohudi, in the face of the dry corpse, it is a real fear, in the face of the fear that can be seen and touched, the human spirit bears much stronger than imagined, and now, this kind of ethereal fear, just imagination can force people to collapse.

Fei Yunfan took a deep breath of the turbid air and said, "Go over." ”

The three of them walked towards the light, the lamp was installed on the wall of the cave, it was like the old Beijing brand building, there was a corridor in the middle, and rooms were dug out on both sides, and there were lights in each room, and the lights in some rooms were broken, and it was dark inside.

Fei Yunfan walked into one of the rooms, there was an old-fashioned desk, a chair, and a filing cabinet against the wall, there was nothing in it, only a few pieces of paper in it, Fei Yunfan picked up one, it seemed to be the last page of the document, the content on it was not visible, it was all a fixed format of some government documents, but the following inscription, let Fei Yunfan pay special attention, the inscription is:

The Northern Guard Military Department of the Imperial Capital of the People's Liberation Army of China.

1952 year

Then, a red steel stamp was stamped on it.

The People's Liberation Army of the People's Republic of China is not a simple department, it is a predecessor of the Imperial Capital North Guard Military Region, in 1959, this army was classified as a provincial military department, although it is a provincial military department, the level is the level of the deputy military region, under the direct command of the imperial capital, so to speak, this is the former Imperial Forest Army.

Such a unit should be responsible for defending the security of the imperial capital, and should not be tasked with suppressing bandits, why did they participate in the suppression of bandits, and they also set up a secret outpost here, and they are still hiding so deep underground, what do they want to do?

Also, all the previous speculations may not be correct, this army discovered the mechanism of the Luo Dashan people, and found what they needed, and they did not choose to leave, but set up an office nearby, could it be that they are here to study what they found?

What Wang Xiaoer said about the fact that the head of this company was cut off overnight may not be a lie?

"Brother, come and take a look at this." Oscar is looking through the contents of his desk.

Fei Yunfan walked over, and Oscar handed over an old-fashioned notebook, with a red plastic shell, with a Mao Da head portrait on it, and a Mao Da quote next to it.

Study hard and make progress every day.

Fei Yunfan turned the first page, and it was the name of the owner of this notebook, his name was Chen Weiguo.

Fei Yunfan then turned the second page, judging from the format, it seemed to be a diary, Chen Weiguo's font was strong and powerful, and he had the courage to be a soldier.

January 4, 1952.

Child, this is the ninety-fifth day that Dad has been working here, Dad has not seen the rising sun for ninety-five days, today is your first birthday, Dad wants to spend this birthday with you.

But for the sake of the construction of the Motherland......

On the ninety-fifth day, it seemed that he had finished writing a diary, this was the second, and Fei Yunfan quickly turned the next page.

January 13, 1952.

This person doesn't keep a diary every day, as if he just encounters major events or special events, and has the habit of taking notes.

Today's research is very unsuccessful, another comrade-in-arms has been infected, our protection has been done to the best, and the source of infection can still spread.
