Before entering the room at the end of the corridor on the fifth floor, it would be better to collect as much information as possible.

Liu Qingjiang was the person in charge of the previous demolition. On the day when the demolition was suspended, he disappeared while on duty. According to the last notes recorded, he saw the light on in the room at the end of the corridor on the fifth floor, so he went to check and then disappeared.

It is easy to imagine that Liu Qingjiang might have seen something on the fifth floor that led to his fate.

Lu Ban can probably summarize some rules now.

First, if you walk up the stairs, you might encounter a baby-sized creature following you, leaving footprints. Perhaps, when it follows you to the fifth floor, something bad will happen. From here on, the missing nurse Xu Xiao did not lie.

Secondly, everyone who had seen the things in the room at the end of the corridor on the fifth floor disappeared, but Lu Ban suspected that they were not missing, but were trapped in this strange space. Just like the statement in the task description, these missing people did not die, they just existed in this hospital in a different way.

Perhaps the entrance to the two spaces is in the room on the fifth floor.

So, why does this space exist?

Lu Ban discovered that there seemed to be only Liu Qingjiang and him on this floor. He walked lightly to the door of the room Liu Qingjiang entered and peeked inside.

Upon taking a look, Lu Ban saw Liu Qingjiang's dead eyes staring at him.

No, he was not staring at Lu Ban, but was staring out the window.

Liu Qingjiang was indifferent to Lu Ban's appearance.

He looked outside for a while, then picked up a shovel and started digging the ground.

The cement floor was shoveled and pitted, and a small hole appeared.

Liu Qingjiang dug for a while before he packed the gravel into a cement bag, put it on his shoulders, slowly walked out of the room, and returned along the same route.

Lu Ban stood against the wall, saying nothing, holding his breath, watching Liu Qingjiang following closely with a bag of cement on his shoulder.

"What is he digging for?"

When Lu Ban saw Liu Qingjiang walking away, he immediately walked into the room and looked towards the hole on the ground.

He saw that there was a human corpse in the hole in the middle of the huge ward.

Those people had simple looks, just like ordinary people you can see everywhere.

But the corpses were already in pieces, and Lu Ban didn't even think that they could be put together into a complete human form.

More importantly, Lu Ban discovered that these people's faces had not rotted and still maintained the appearance they had just shown when they died. Moreover, they were the workers who had died in an accident here before!

In addition to those workers, there were other faces that Lu Ban did not recognize, but he could guess that they must be unlucky people who had suffered some accidents in the hospital.

"Liu Qingjiang was digging these bodies? He dug them out of the floor?"

Lu Ban suddenly felt a chill in his chest, and he found that it was the notebook with a red cover.

He hurriedly opened it and saw that on the last page of the notebook, which was stained with mud and water, black words began to emerge. It was a handwriting different from Xu Xiao's, very neat and meticulous.

"It's very cold, but the construction is not going smoothly. There are some problems with the soil structure here. The foundation is always not laid well, the steel bars are easily crooked, and the cement cannot be poured. The construction period is passing day by day. It's too difficult. Those foreigners rely on their wealth to order people around. Those fake foreigners are not good people either. Alas, if the money was not too much, I would not have accepted this order."

"I heard from the locals that this place used to be Caishikou, where people beheaded people. The executioner would take a sip of wine and spray it on the blade, and the onlookers would cheer. He would then throw away the sign on the prisoner's back, raise his blade, and slash a head off. The onlookers would cheer again, and the blood from the head would seep into the ground day after day. The resentment of those who were beheaded would linger here, so nothing built here would last long."

"I'm not superstitious. I've looked into geological data. Because this place used to be a river channel, the soil is mostly sedimentary soil. Later, the Lingjiang River changed its course and this place became land. Therefore, the soil is loose and not conducive to construction. If you want to build a five-story hospital, you must strengthen the foundation. I'm an architect who graduated from Jiangcheng University. These problems are not difficult for me."

"But the difficulty of construction here obviously exceeded my expectations. The designed structure may not be realized in reality. The foundation has never been laid properly. After a long time, only one-third of it has been laid. The workers are getting more and more irritable every day, and all kinds of rumors are spreading."

"The turning point came on the second day of the new year. A worker who was on duty here on New Year's Day fell on the construction site. He slipped and fell into the newly laid foundation. The sticky cement swallowed the worker in an instant. I hurriedly wanted to ask someone to fish him out, but the foreman next to me stopped me."

"He said that the foundation was laid with great difficulty. If we start to rescue the people, the whole structure will have to be rebuilt. If we start over now, we will definitely miss the deadline and everyone's work will be in vain. Moreover, after he said that, he told me mysteriously that if the worker falls in, he will be a living pile. The yin energy here is heavy and must be suppressed by human energy. If it were in the past, we might have to find people with low lives to fill the gap. Now that this worker has gone down, it's just right."

"I don't understand why this feudal superstition is so deeply rooted. I asked people to rescue the worker, but no one dared to move, for fear that they would also fall in. Seeing that the cement had solidified, I had no choice but to give up. After all, no one can afford to pay for the delay in construction."

"Oddly enough, ever since that worker died in the foundation, the work on the foundation has gone much smoother, with almost no problems encountered. All the foundation has been laid, and construction is on track."

"I have never believed in these things, but I can't help but doubt whether the saying of living people being staked really exists."

"Until the Chinese New Year, we encountered a problem with the main load-bearing beam. The construction progress was delayed, and the workers went home again. The work came to a standstill again. I walked on the construction site and looked at the main load-bearing beam that could never be built. I felt very upset."

"I saw a worker standing next to the load-bearing beam, pouring cement into it. It was strange because I clearly didn't ask them to pour it. I called him and the worker seemed to be startled and slipped and fell into the cement."

"I immediately ran over and grabbed his hand. He asked me for help. Most of his body was stuck in the cement. He pulled me hard, but I couldn't hold on any longer. He hurt me so much that I almost fell in. I shouted for help, but there were few people on the construction site at the time."

"I held onto him like this. I don't know how long it was. Then, all of a sudden, the foreman's words came to my mind. The worker was already halfway into the cement. He didn't even have the strength to hold onto my hand. If I let go, he would fall."

"I have tried my best. I have tried my best. I have done nothing wrong. Moreover, as long as he sinks, the hospital will be built and everyone can get the money. I thought so and let go of my hand."

"I just watched him sink, and suddenly I felt extremely relieved. After calling the police, I went to the bathroom and looked in the mirror. I found that I was smiling."

"The construction of the hospital is completed. I received a generous reward. The families of the deceased workers received a huge sum of money that they could not earn in their lifetime carrying bricks. Everyone is living a better life. However, sometimes I wonder, when I walk into this hospital and stand next to those pillars, will the people in those pillars smile at me?"

Lu Ban saw that the words were no longer neat at the end and more like those written by someone with epilepsy or a physical illness.

Sensing some movement, Lu Ban raised his eyes from his notebook.

He saw Liu Qingjiang standing at the door holding a shovel.
