Chapter 63 Chapter 63: The Blockade of Iron Plates

A did not drill in, but put the planks back in place.A lot of time has passed, he must go back to the cell to avoid the guard's night inspection, and come back later. Today, the night check of the guards in Building 1 is still very punctual. The guards shine a flashlight at the door of the cell until they can see the face of the person lying on the bed. A is also very troubled by this. Since the underground passage is blocked, almost one-third of the time spent on the road can be taken up each time, and the danger is also greater than usual. To do it well, don't be careless at all. A drilled down the passage again, and this time he was familiar with the road, and it didn't take long for him to come to the basement of Building No. 3 again.

A uncovered the piece of wood and jumped into it. It was pitch black inside, and the smell was even worse than that in Building No. 1. A crawled forward in the dark for a short distance, and then saw a ray of light coming out from the corner ahead. When A climbed to the place where the light was shining, he found that it was a small gap on the outside of the passage. A put his face on it, looked in through the small gap, and at the same time, a stench rushed straight into A's nostrils from the gap.There is the huge cesspool under Building No. 3.Due to the rain, the water level in the cesspool is relatively high today, and night light penetrates from a plate cover above the edge of the cesspool, shining on the water surface and refracting to the gap.Although very faint, it is still very noticeable in a completely dark passage.

In A's memory of the architectural drawing of the Baishan Pavilion, it seems that this big pit does not exist. So A took out the coil of iron wire again, felt it carefully, and then determined that it should be an underground facility that was remodeled later.Looking carefully, the walls of this huge cesspit are made of cement, not the brick and wood materials that are mostly used in other basements. This made A very worried. Has the underground structure of Building No. 3, especially the underground structure of the related parts, undergone tremendous changes? A continued to climb forward, but did not climb very far, the passage has come to an end. A looked out at the end, and a mezzanine between vertical walls was displayed in front of A.

A turned around in the passage, put down his legs first, and slowly climbed down the mezzanine.This mezzanine is only as tall as one person and one meter wide, so when A goes down to the bottom of the mezzanine, it is relatively spacious and can turn around flexibly.There is light coming in from the small holes at the top of the interlayer, and the interlayer is not so dark in the backlight, and people with better eyesight can see everything within one step. There was water at the bottom of the mezzanine, which was as deep as the ankle. A lifted his feet and found that there was not a lot of dirt and mud, and the water did not stink. A took off his shoes and socks, pinned them around his waist, leaned forward step by step with his hands on the wall.

After walking about three or four meters, A stopped.There is a stone bridge more than one meter high and two people wide in front of you.On the side of the stone bridge facing the courtyard on the second floor, there is actually a small wooden door embedded in the wall. A was secretly happy, and climbed up the stone bridge. A first touched the wall on the side of Building No. 3. It was obvious that there should have been a door here, but it was built on. The material of the masonry was completely different from the wall next to it. Different, it should have been built for less than a year.

A turned around and pulled the small door on the other side of the stone bridge.The small door was just a decoration, A pulled it with his hand, and the whole door leaf fell off, it seems that it has not been fixed on the wall for a long time.But this startled A, and hurriedly supported the small wooden door, lifted it up and leaned against the stone bridge. There was no passage in the wooden door, but it was also blocked. A felt it carefully, and was even more surprised.It was actually blocked with a whole steel plate, looking at the traces, the steel plate was installed from the inside.In other words, if you want to get through here, you have to wait until the entire wall on both sides is dug out and the steel plates are removed before you can move forward.

There are four steel plates in total, each of which is more than two feet high. A felt it, and there was a gap between the two steel plates, just enough to dig his hand in. The steel plate was about the thickness of a fingernail. A pulled it hard, but it didn't move.So A gave up and continued to pull the steel plate, and groped outward along the steel plate. As expected, the steel plate was installed from the outside to the inside, and the two ends were buried in the wall. I don't know how long it is. A knocked on the wall until he knocked a foot away before he heard a different sound.That is to say, if one piece of the steel plate is to be removed, a foot-long and two-foot-high wall soil must be dug along the steel plate on both sides of the door.With one person and a few pocket tools, it will take at least nearly a month to excavate such a large area, and depending on the thickness of the steel plate, even if it is dug up, it will take at least three or four people to use tools to pry the steel plate off. piece.

As shown in the picture: A can't complete this task alone, but A immediately thinks of one person——Zheng Xiaoyan and the person he said must be brought along to escape from prison. A lifted up the wooden door, covered it again, and turned back. At the gap where the huge cesspool could be seen, A endured the stench, observed it more carefully, and with the faint light, took out the iron wire engraved with traces, and touched it carefully.In my mind, the architectural drawings of the basement of Building No. 3 slowly came to my mind. Zheng Xiaoyan and the others must be able to come down to the basement, and they must be given enough reasons and time to complete this matter.

A sat quietly, almost melting into the darkness.Beads of sweat on his forehead ran across his cheeks, but A didn't notice it, and just kept stroking the wire back and forth with his hands section by section. From the perspective of others, this period of silence seems to have passed ten thousand years.But in fact, after five or six minutes, A started to move.He quickly drilled through the tunnel and climbed down again from where he came up. A did not return to Building No. 1, but ran to the end of the basement of Building No. 3. Building No. 3 was silent, the lights were dim, and the figure of A was like a ghost, flashing forward quickly.

At the very end of the basement of Building No. 3, there is a large open room surrounded by a large amount of waste, dry grass and dense firewood. A soon found a blocked door on the wall that could lead to the mezzanine.Despite being reapplied with a thick layer of plaster, the walls are a completely different color than the surroundings. The upper corner of this room has a cold wind blowing in, and there is an air inlet there.It is connected to the mezzanine that A entered just now. A stretched out his hand to feel the direction of the wind. The air volume of this air inlet was enough to blow the smell of this room throughout the basement of Building No. 3.

A came to the other corner of the room, squatted down, and carefully removed some of the waste piled in the corner, exposing the corner. A reached out and touched the corner of the wall, it was damp and soft, and brought his hand to his nose, he could faintly smell a stench.So A took out a small knife and scratched a few times on the corner of the wall, and A simply dug out a small piece of the wall. A speeded up, and after a while, two clay bricks were dug out. A continued to dig, and the progress was very smooth. With his hand, he could touch the inner surface of the cement that was completely different in material. A breathed a sigh of relief, this time he also took out the small saw, and drilled holes in the innermost concrete wall bit by bit.There was a slight click, and the small saw had drilled through the inner wall, and a sour and smelly liquid oozed out of the small hole. A doesn't care so much, and continues to slowly saw from this small hole horizontally. It didn't take long, and a straight line was sawed on the inner surface, and more sewage came from several cracks in this straight line. Seep everywhere. A stopped moving and put away the small saw and knife.I stuffed two of the pieces I took out into the nearby hay pile, and put the remaining two back in the corner.Then he piled up the sundries in the corner, turned around and turned back. Time limit again, A has to go back. In the corner dug by A, before the huge cesspool was built, the innermost part was nothing but boundless soil.But the appearance of the cesspit connected the corner road of this room with the cesspit, and if the wall was dug through, the manure inside would probably be poured into this room. But, not today. Therefore, when A came to the corner of the room at the end of Building No. 3 again, he just continued to saw the innermost concrete wall. He saw the straight edge straight down from the last time to form a cover. Shape, then, punch holes in all four corners.Let water flow out of each hole, and then stop. Although this shape is not very big, it requires a lot of wrist strength and skill. When A finishes all this, he is already tired and sweating. A still used bricks to plug the hole, and covered the corner road with sundries.Turned back. A was exhausted and his heart ached, so he didn't go on tonight and fell into a deep sleep.
