As far as the eye can see, there are hundreds of iron nails inlaid on this wall alone, and where these iron nails are inlaid with the wall, there are even small pieces of paper!

"This ...... Did something hang on this wall before? ”

After seeing these pieces of paper, Lin Yongjian's heart suddenly burst out, and he turned his head to Lin Cheng and asked.

Seeing that Lin Yongjian finally understood, Lin Cheng nodded and said in a deep voice: "That's right! These pieces of paper can only show one thing, that is, the people here did not panic at all, and even methodically took away all the evidence that might reveal their secrets! ”

Hearing this, Lin Yongjian's heart suddenly changed again, "You mean...... It may have been an experimental drawing or something hanging on this wall before?! ”

"Quite possibly!"

Sighing softly, Lin Cheng carefully peeled off these messy pieces of paper from the wall one by one, placed them neatly on the table, took out his flashlight and observed them carefully.

"These grandchildren!"

After ten minutes of observation, Lin Cheng couldn't help but curse secretly, these scraps of paper were obviously just the corners of those drawings, either they were blank, or there were a few lines that couldn't see the meaning of Qi at all, and there were no useful clues on the hundreds of scraps of paper......

"These grandchildren!"

Finding that he couldn't get any clues from these confetti, Lin Cheng finally had no choice but to give up, and instead began to check the experimental equipment that he had just ignored.

Although Lin Cheng studied in college for four years, he only studied ancient literature, and he had touched very little experimental equipment in college for four years, but he had never seen pork or pig running, even if he didn't see too much normal experimental equipment, but he also knew what it looked like, but he had never seen any of the equipment in this laboratory.

After a while, Lin Cheng, who had checked almost all the experimental equipment, frowned, and his mood became more and more unpleasant.

Without exception, all of these experimental equipment have been carefully cleaned, and there is no trace of any trace that may have been collected by others, except for the dust that has been abandoned for a long time!

Some did not believe in evil, Lin Cheng simply walked out of this laboratory, opened all the doors on the entire second floor, and searched one by one.

This building seems to have belonged to the scientific research floor from the second floor, all the rooms have been specially built as laboratories, and the furnishings inside are similar, but without exception, all the evidence that may expose the secrets of this research institute has been deliberately erased, and the entire second floor has been searched, and Lin Cheng has found nothing!

"It seems that the secret that these people want to hide is very important......"

After discovering this, although Lin Cheng was not in a good mood, he could be regarded as understanding that the water in this research institute was much deeper than he imagined, and these people would still have to erase and take away these evidences even after the end of the world, so you can imagine how important it is!

"That...... Why don't we go up to the third floor and have a look? ”

Finding that Lin Cheng's expression was not very good-looking, Lin Yongjian hesitated for a moment, and then suggested to him.

In fact, Lin Yongjian himself was also in a very bad mood after discovering that the evidence of the entire research institute had been deliberately erased, and he, like Lin Cheng, wanted to know what caused the current situation, but after coming here, he found that all the clues that might help them solve their doubts had been erased, and this sense of disparity made him endure for a long time before he resisted the urge to scold.

"Third Floor ......"

Hearing Lin Yongjian's suggestion, Lin Cheng muttered softly, in fact, after reading the situation on the second floor, he didn't have much hope for the floor above, since these people had the kung fu to take away the evidence on the entire second floor, there was naturally no reason to give up the evidence on the upper floor.

However, no matter what, since you have come here, you still have to read all the places where you may find clues to feel at ease.

Thinking of this, Lin Cheng nodded, and then he didn't bother to talk nonsense, waved at Coke, and then turned around and walked towards the third floor with Lin Yongjian.

After half an hour of careful searching, the two people who had searched the entire three floors were sitting on the floor on the floor one after the other, smoking cigarettes, and the expressions on their faces were even more depressed.

As Lin Cheng expected, the third floor is indeed no different from the second floor, the same laboratory layout, the same evidence has all been erased, and even the position of the iron nails on the wall is almost the same, and the entire third floor is almost a replica of the second floor......

"What do we do next?"

After taking a hard puff of the cigarette and circling around his body, Lin Yongjian exhaled a puff of smoke, and then asked Lin Cheng on the other side.

Hearing this, Lin Cheng smoked the last puff of tobacco, threw it on the ground and stepped on it, and replied, "What else can I do?" Of course, I continued to search! This building has six floors, and we're only halfway there. Although there is little hope, there may still be some bits and pieces of clues upstairs, and we should be able to find some if we search carefully enough...... Right? ”
