Chu Wei put on Yansheng's coat and climbed down the ladder neatly.

Beneath the deep passage was a door, a heavy iron door, on which hung a locked chain that also looked heavy, and Yan Sheng tried to lift it, the sound of metal clashing echoed through the silent passage.

"We must be underground now," Chu Wei took out his mobile phone, but there was no signal at all.

"Come on Hammer, try it." Yan Sheng took out the iron bar that Chu Wei picked the lock from his bag.

After tinkering in the lock for a long time, Chu Wei had a thin layer of sweat on his forehead, but this lock seemed to be more difficult than he imagined.

Chu Wei pulled out the iron bar, "This lock may not be an ordinary way to open." ”

Yan Sheng was puzzled: "But this lock looks the same as the old-fashioned lock that is opened by the key, although it is a little bigger, what else can be opened." ”

"Let me take a closer look."

Yansheng gave Chu Wei a light, from the lock to the chain, Chu Wei looked at it inch by inch.

Suddenly, a cacophony of voices came from above the passage. It seems that more than two people are talking, and it is difficult to tell what is being said, only that it is all male voices.

"Shhhh Chu Wei quickly pulled Yan Sheng and leaned against the door, holding his breath.

The sound of talking got closer and closer to the passage, and just when Chu Wei was about to vaguely hear what they said, the conversation stopped abruptly.

The two clung to the door, waiting for what might happen - to be discovered.

Extremely quiet, more than ten minutes later, it was still extremely quiet.

"It should be the kid who went to the toilet next door," Yan Sheng opened first.

"But I don't feel like the sound was a child, it was supposed to be an adult man." In the dark, Chu Wei moved his back a little stiff.

"Maybe it's the uncle in the duty room, getting up in the middle of the night to go to the bathroom. Okay, hammer, the most important thing for us now is to open this lock. Yan Sheng turned on the flashlight and shone the lock again.

When he saw a strange crack in one of the chains, Chu Wei tried to break it, and the entire chain was actually broken from here.

Yan Sheng's eyes widened: "I really didn't expect this lock to be opened like this!" He felt his IQ being pressed to the ground and rubbed, "Who designed this, what a talent." ”

"It's the first time I've seen it, too." Even Chu Wei helped his forehead.

It took a lot of effort for the two of them to remove the chains from the door.

Pushing open the rusty iron door, sure enough, there was a room behind the door, a small room.

The room was cold and there was no trace of popularity, if it weren't for the light of the mobile phone, Yan Sheng would almost think that he had walked into a cave deep in the mountains.

There was only a table and a cabinet in the darkroom, and judging by the style and newness, the furniture seemed to be a little older than the room above, especially the middle of the table was very worn, and it may have been used for a long time.

The two searched the cabinet one and the other turned over the table, and began to look for information about Shen Lanjun.

There are a lot of books from some years on the cabinet, such as "*** Anthology", "Song of Youth", "Drug Handbook", "Double Helix - The Story of Discovering DNA Structure", etc., there are many types of books, politics, history, novels, medicine, etc. There are still a lot of old newspapers, and Yan Sheng is extremely careful to turn them over, for fear that if one does not pay attention to the newspaper, it will be broken into pieces.

Chu Wei pulled open a drawer under the table, and under the drawer was a newspaper that had been mixed with the contents of the building. Inside there is a roll of paper, a white enamel jar, and some short pencil heads, full of age. Flipping through it casually, there didn't seem to be any valuable clues in this drawer, so Chu Wei took a photo and closed it. He continued to open another drawer, and inside was a stack of newspapers, the contents of which were nothing special, but at the bottom of the newspaper, Chu Wei found a few pieces of paper. Guessing whether it would have something to do with Shen Lanjun, Chu Wei immediately looked at it.

This is a proposal for a medical research project, the topic is about the ex vivo development of embryos, the person in charge is named Zhao Bin, and the date is January 20, 1950. "Ex vivo development of embryos? Why haven't I heard of this research project? Chu Wei said in confusion while looking at the contents.

"Ex vivo development of embryos?" Hearing Chu Wei speak, Yan Sheng suddenly turned his head, "I remember that I seem to have seen these words in the dean's office!" ”

Yan Sheng came to Chu Wei's side and took the plan and flipped through it, nodding while reading: "I'm sure, I saw this document in the dean's office, but it was a photocopy." ”

"The Dean's Office?" Chu Wei narrowed his eyes.

"Yes, when I went to look for the file that day, I accidentally saw this in his drawer, and I was only thinking about looking for Shen Lanjun's information at that time, and I didn't care about this thing at all. But the fact that this document appears here and in the dean's office suggests that the dean may have some connection here, right? ”

"What kind of person is your dean, Wei Qian?" Chu Wei continued to ask.

Yan Sheng sat on the ground and said slowly: "He is a very caring person. It is said that many of the children in our welfare home were adopted by him, and without him, many children might not have survived. Me too, and if it weren't for him, I'd certainly not be in front of you right now. ”

"You know, I was too naughty when I was a child, I didn't have my father and mother to teach me, and I always did some sabotage. I often take my friends to hit the glass with slingshot competitions, I used to be really too badly beaten, hehehe," through the light of the mobile phone, Chu Wei found that Yan Sheng had a warm smile on his face, "but many times he found out, we thought he would reprimand and punish us, but he didn't." He took us to pick up the broken glass on the floor, and then asked us to install the new glass together, and gradually we felt that it was boring, and gradually understood his intentions. When I was playing hide and seek, even if I was caught hiding in his office, he wouldn't embarrass me, just screaming 'little bunny' for me to get out. We are not afraid of him, we all respect him from the bottom of our hearts when we grow up, although his name is Wei Gan, but he is really not for money. ”

"Well, he seems to be a good man. But his relationship with this dark room is unknown. Chu Wei got up and carefully tucked the plan into a book in his bag, and then continued to flip through the drawer on the other side of the table.

The drawers were all empty, Chu Wei knocked on it, and there was no mezzanine, he turned around and rummaged through the cabinet with Yan Sheng.

Looking through the rolls of newspapers, there was no paper or note in them, and there were no clues. The books on the cabinet were all flipped through, and there was nothing of value in them. For a while, the two didn't know where to start.

The high level of mental concentration made them all sweat a little.

It's been more than six hours since the last meal, and the stomach has been emptied, and Yan Sheng's stomach is gurgling out of place.

Chu Wei took out two bags of bread from his bag and handed one to Yan Sheng.

No useful clues were found, and the two ate in silence. Chewing, Yan Sheng suddenly sighed and said, "I really want to eat red beans, I'm here for meat floss."

“......”。

"I thought of it!" Chu Wei, who was still speechless just now, stood up.
