Xiaohua was very focused, her sleeves rolled up high to reveal her not very strong arms, and some hideous lines were all over it, stretching and curling up with the beating of her muscles. Although his hammer was wielding with great force, the progress of the project was not very promising, and the black bricks under the cement had just been knocked off half of the thickness. Seeing this, I let out a sigh of relief and hurriedly told him to stop.

Xiaohua heard my voice and lowered her head and asked me, "Why did you stop?" You're going to do it for me? ”

I steadied myself and explained it to him. After listening to this, he thought for a moment, threw away the hammer, sat cross-legged on the oil drum, sighed and asked, "Then what should we do?" ”

How do I know what to do, Xiaohua obviously understood this, and sighed again and leaned back against the wall. I looked at the little blonde hair that showed out from the back of Xiaohua's pointed chin, and suddenly asked, "Xiaohua, do you have a girlfriend?" ”

Xiaohua, who was sad like a religious painting just now, suddenly became irritable, but quickly calmed down again, and casually spit out, "What's your business? ”

It is said that it is normal to have a good chat and learn about the family background of the class, because you have to be angry when you are scolded, but I didn't pay attention to his words, because my mind has already been completely attracted by something.

Behind the little flower is that earthy yellow wall, what is behind the wall?

When I first came there, I speculated that there was still a lot of space behind this wall, because the predecessor of this place must have been a human defense fortification, and no matter what it was used for, it was too small. Even if it was built for a big man, the room here would not be large enough to fit those attachés, let alone a large amount of living and war materials. There is no vent design, and there is no trace of the vent being closed, and there was no such thing as air conditioning in those days, so it can only be that it was just a part of the civil air defense fortifications. What's more, no one wants to be trapped in a dead end in times of danger, the detached courtyard is only designed in peacetime, and who wouldn't leave a back door for themselves in times of war?

That back door, right behind this wall!

"Smash this wall!" I pointed behind Xiaohua and said.

"Why?"

"There's a road ahead!"

"How do you know?"

I didn't bother to explain in detail, but simply said: "I studied engineering, there must be another exit in this place, the material of this wall is different from other places, the exit is in the back!" ”

Xiaohua very brainlessly believed my unreliable explanation, and turned her head without talking nonsense and smashed it. I wanted to find something to help, but Rong Yusi tugged at my clothes and motioned for me to go with her. I looked at her strangely and followed her into the house.

"Si'an, what you just said is not right!" Rong Yusi stared at me and said, "It's not that simple, they're simple-minded, I'm not!" ”

"Who are they?" I secretly laughed in my heart, Rong Yusi would ask me like this, as if I had some big conspiracy, could it be that I looked like a big traitor?

"They are who they are!" Rong Yusi didn't bother to explain the question, "What do you think?" ”

I suddenly felt a headache, women are really strange creatures, is this kind of thing so easy to pursue? Seeing that Rong Yusi was staring at me, I had to explain the basis of my inference again.

After listening to this, Rong Yusi lowered his head and thought for a while and said, "Your brains are good, no wonder you ......"

"What?" I didn't understand, and asked.

"Nothing, what do you think will be behind the wall?"

"There won't be anything, it must have been cleaned up when it was closed here, and even the exit over there was closed."

"What's the point of doing that?"

"Of course it makes sense, the exit here is something we can't get out of no matter what, maybe we still have a chance over there!"

"But have you ever wondered why this place is closed? Is there any reason why it has to be closed? ”

"Do you have a better way?" I didn't answer her, I asked rhetorically.

Rong Yusi didn't speak again, I added, "Take one step at a time!" ”

Outside there was the sound of small hammers, and Gejia outside the door was disturbed, but I fell asleep in the noise.

I had a dream in which there was a lot of mess, but it ended with a pale flame behind the wall. I woke up in the flames, and suddenly there was a clear picture in my ears, and the little flower was saying, "All right! ”

The wall had been smashed through a hole the size of a washbasin, and the smell of rotting dust wafted from it. I guessed right, there is indeed a big space behind it, a black hole, and you can't see anything at all. I lay down at the mouth of the cave, breathing in the rotting and rotten air inside, and looked inside with a flashlight.

There are about 1,000 square meters inside, and it looks very empty, except for some high and low platforms that I don't know what they are, and a circle of partition walls along the wall. There were very old electric lamps hanging down and scattered on the top, and some disc-shaped lamps hanging from the platform.

Xiaohua also leaned over to me and looked in, sniffling and asking me, "Want to go in?" ”

I turned my head to look at him, "There's nowhere else to go, let's try our luck in there, it's better than here." ”

"Then you won't leave?"

"Let's go!"

I took a final photo and didn't see any danger, so I put my feet in front of and behind me and smoothed myself down.

The feet are solid and there is not much floating dirt. Turning around and looking around carefully, being in the middle of it, surrounded by that smell of air, gives people a very strange feeling. I simply walked through a hole in the wall, but it was as if I had traveled through time and space, and everything in the past was no longer real like a dream.

Rong Yusi and Xiaohua also drilled over, and Rong Yusi exclaimed: "You are right, there is indeed a house here!" ”

I shook my head and said, "Let's take a look, I don't know if there is a way out!" ”

We began to search around the room, and it was clear that it had been full of stuff, and that there were many marks on the floor that resembled a push-and-pull weight, presumably left over from the time we emptied the place. In addition, there are some traces left by the perennial push and pull trolley, which makes me wonder if this was once a warehouse.

After a round and turn, we were dismayed to find that there was no exit here, and that the whole fortification seemed to end there, except for a huge steel plate laid on the ground in the corner of the room, which was tightly welded and nailed to the ground by huge steel bars.

I don't think it's normal, and I don't know what special needs there will be here to pave the floor with steel plates. But from this fixed way, it is more like closing the entrance than as a floor.

Xiaohua had no interest in this, and walked around the room by herself, and I knocked the steel plate with the handle of the knife, trying to hear if it was empty underneath. At this time, Xiaohua quietly came over and said mysteriously: "Come here, I'll show you something!" ”

I startled him, "What's so mysterious, can't there be a ghost here?" ”

"I don't know if there are ghosts, but there must have been deaths here!" Xiaohua smiled wickedly and pointed to the high and low platforms.
