Shrouded in complete darkness, his senses have become acute, especially Hao Dong at the moment, although his perception of his surroundings has become very numb, the senses of his body itself seem quite keen. In addition to the drastic drop in body temperature, the noise in the ears is also getting louder.

It wasn't the sound of the wind that should flow here, it was the sound of people coming and going, complicated and chaotic, as if they were discussing something very important. Hao Dong knew that the center of their discussion was him, but what were they discussing about him?

He couldn't hear or see clearly, and there were many pictures in his head, but none of them were clear enough. There seemed to be a lot of doctors, nurses, and a lot of different medicines. The pain comes from all over the body, probably because you have received a lot of treatment here?

But if it was a serious treatment, why did he not remember anything afterwards and was picked up like a stray puppy? No, it can't be some serious treatment, it's some kind of experiment...... But what kind of experiment is that?

Hao Dong had a splitting headache, unconsciously holding his head and almost rolling on the ground, this state was a test of willpower, even more difficult than being locked in the freezer last night to make human flesh jelly. At least last night's state didn't have this heart-rending feeling from the inside out, and there was still Qi Jue by his side at that time. The situation of not being alone is undoubtedly very comforting, especially when it is accompanied by a strong existence that can be relied on.

Hao Dong felt that he was about to lose his support, maybe he could be a little more comfortable just passing out. It's a pity that he has such a thought in his heart, but his body is not cooperative, although he feels that he can't hold on to the headache, in fact, his mind has always been awake and active, as if he was stimulated by something, and the excitement can't be contained.

Then, when this excitement reached its peak, Hao Dong was suddenly stunned. He remembered a very clear face, a middle-aged white coat holding what appeared to be a medical document, hiding it under the floor tiles under a corner of a hexagonal room.

The headache began to subside as Hao Dong recalled the image, and after a quarter of an hour, Hao Dong felt that he was finally alive. Although it is still very depleted, at least there is no longer the feeling that I can't even breathe.

It was still dark all around, and the flashlight was rolling a meter away, and the bleak light illuminated a small piece of ground in front of the barrel. Not far away is a wall, which looks familiar.

Hao Dong blinked vigorously, struggled to sit up, picked up the flashlight, and carefully checked the ground again, and found that it was very similar to the place where the middle-aged man had just seen the case in his memory.

In particular, he remembered that there was a knife-carved cross pattern on the wall near the ground at the base of the wall, about the size of a dime, and he would not have noticed it if he didn't get around it. And the root of the wall in front of him has such a pattern.

Hao Dong stood up and circled the room in clockwise order, paying special attention to each wall root to see if there was any other pattern of that kind.

Six walls, six doorways leading to other rooms, each of which was dark, and from time to time a cold wind blew out, and it was cold. There was a doorway to the room that seemed to be a lounge before, and a discarded white coat hung on the collapsed pile of sand and gravel, the cold wind blew, and the corners of his clothes would rise and fall, and Hao Dong was scared into a cold sweat when he shone a flashlight.

Fortunately, this room was not as big as the previous hall, and after a few minutes, Hao Dong returned to the original corner, and made sure that only this corner had this pattern.

Now that it was confirmed, he didn't waste any time, and immediately crouched down to carefully inspect the ground.

There are a lot of gravel on the ground, but fortunately, the volume is not very large, and Hao Dong took a little effort to clean up the similar area.

The surroundings were still dark and silent, Qi Jue and Ergou seemed to have evaporated from the world, and no one else appeared to stop Hao Dong's actions. This situation is actually very bottomless, so Hao Dong's movements are getting faster and faster. He wished he could have dug up the thing underneath sooner, and his instincts told him that it had something to do with him.

The style of the terrazzo floor does not look like the current decoration at all, but more than ten years ago. The filling material was poured between the brick joints, and Hao Dong had to lie on the ground and carefully use the flashlight to observe one by one.

His dream was obviously very reliable, and when he checked the third seam, he found something different from the one on the side. He took out the Swiss knife beside him, and scraped out the filler in the brick joint with a different color from other nearby brick joints, and soon, a hole enough for him to insert the blade into appeared.

As he expected, the brick surface was very thin, only about three centimeters thick. The bottom of the brick was empty, and the blade of his Swiss knife was easily inserted into it, and when he pressed hard on the hilt, the whole brick suddenly loosened.

The crowbar is in the second dog's bag, and although the bricks in front of him are loose, they haven't been able to fully get up. Hao Dong rummaged through his bag for a long time, but did not find a suitable tool, only a signature pen. Fortunately, the brick is not thick, and it is not heavy, and after the Swiss knife lifts a part, he inserts the signature pen into it, and the two are forced together, and when the width of the crack can be stuffed into the finger, Hao Dong directly opened it, and it was refreshing all of a sudden.

After uncovering the bricks above, Hao Dong found that the hole under the bottom was actually not big, at most five centimeters deep, and if the bricks were put back, the height of the entire space would be about two centimeters. The book was just thrown inside, already damp, the paper was soft and crumpled, and the handwriting on the cover was blurred, with a peculiar smell of earth.

Perhaps because it was originally a hospital, even if it was turned into ruins, Hao Dong still regarded this place as an artificial building when he was active here. In other words, in his concept, this place has nothing to do with the concept of "nature".

But now he dug a dirt pit, and suddenly he thought of the rat that ran over his instep before, so maybe there will be a centipede or something?

This thought gave him goosebumps all of a sudden, and he immediately picked up the case, and the person quickly stood up. I remembered that I had a splitting headache just now and lay on the ground, and I suddenly felt uncomfortable.

Of course, he also knew that there was no point in picking on these at this time, but the dirt hole gave him a really bad feeling, and in the end, he still walked a little farther before he had the heart to take a closer look at the case in his hand.

The case was already watered, and the handwriting on the cover was blurred, and only a date was recognizable, as well as a number that appeared to be a patient number. The pages that followed the cover were also watered and glued together, and they could only be patiently torn apart one by one.

At the beginning, some records were nothing more than test sheets that recorded physical data, Hao Dong didn't know anything about these numbers, and could only judge according to the appearance of arrows behind the numbers.

After the small red arrow indicating that the data exceeds the standard is increased from two or three to a whole piece, the subsequent content enters the manual recording stage.

The doctor's handwriting is difficult to recognize, but apparently there is more than one doctor who has made notes on this case, and one of them has relatively neat handwriting, and Hao Dong can roughly understand that they seem to be conducting an experiment called memory reconstruction.

This kind of name, even as the name suggests, can guess a little bit of the experimental content. Hao Dong wanted to continue to look down, but suddenly there was a loud "bang" above his head, followed by a series of sounds, as if something like a cabinet had been knocked down by a chain.

If it was the sound that those guys hiding here accidentally made, Hao Dong would definitely not believe it. If these people were to be rude to this extent, they would definitely not be able to hide it for a long time. It is more likely that Qi Jue and the people hiding here have confronted each other, and they knocked things down during the fight.

This sound is loud enough, judging from the previous situation, it is impossible to say that the people who are guarding outside will have to come in again to check after a while, Hao Dong feels that he must not have time to read this case. Originally, he wanted to stuff things directly into his bag, but then he thought it was wrong, in case he was caught again, wouldn't the other party be exposed when he searched it? What if it is confiscated directly from him when the time comes?

If you can't take it out, you might as well put it back in the same place. After all, he didn't know what the doctor's purpose was in hiding this medical record, maybe they had some internal agreement of their own, and it would be a surprise to take it directly.

Thinking of this, Hao Dong quickly shrank back into the corner, took out his mobile phone, and quickly took pictures of every page in the case.

The light of the flashlight is actually not enough, but fortunately, their mobile phone this time is still the kind of customized special machine, and the night shooting effect is excellent, even if the light is insufficient, the handwriting on the picture is still clear. Hao Dong was slightly relieved, and dozens of pages of cases were quickly filmed, and he immediately buried the cases back as they were.

Maybe he was too attentive to his work, and when he turned around, he was almost frightened, because when he didn't know it, there was a person standing behind him.

Qi Jue saw Hao Dong's state and knew that he was scared, and immediately reached out to cover Hao Dong's mouth. As soon as he found Hao Dong, he found out that he was hiding something, and he wanted to ask out loud, but Hao Dong suddenly turned his head. He has been trained since he was a child, and he can act completely quietly, so he scares people, and he himself is quite helpless.

Hao Dong, who was covering his mouth, quickly saw who was coming and calmed down. Qi Jue let go of him, gesturing for him to follow, and the two of them went one after the other, burrowing into the doorway with the white coat, and quickly returned to the basement entrance on the first floor of the main building.
