Chen Nan received a call from Zhao Zhongzheng, a little surprised, and asked, "Team Zhao, aren't you resting at home?" ”

"There's a mission, you go and help me check the evidence of the murder demon case, whether there is a seating table and a lollipop in it."

"Isn't that case closed?"

"If you are told to go, you will go, what is so much nonsense, call me after checking" After speaking, Zhao Zhongzheng hung up his mobile phone.

"I've already asked someone to check, now I'm going to communicate with the school leaders, and you wait for my news."

"Okay, fortunately, Team Zhao, I wish you smooth communication, we are waiting for your good news" Chenxing responded.

"You clever ghosts," Zhao Zhongzheng got up to leave.

Principal Yang Shixian's office.

"Captain Zhao, oh, no, no, no, I should call you Director Zhao now, I didn't know that you were coming, and you would be disappointed" Yang Shixian had already learned the news that Zhao Zhongzheng was about to be reinstated.

"Principal Yang is polite, you still call me Xiao Zhao."

"How can this work, Secretary Liu, soak two cups of good Longjing" Yang Shixian said with a smile on his face: "I don't know what you are doing this time?" ”

Zhao Zhongzheng didn't bother to talk to him, and said straight to the point: "That's the case, Principal Yang, do you remember the disappearance of a female classmate from your school a year ago?" ”

"Of course I remember, but there has been no clue in that case, hasn't it been shelved?"

"Yes, at that time, on the one hand, because there were no clues for the time being, and on the other hand, because there was another big case that needed to be solved, a large number of police forces were deployed. But now, there are some clues in this case," Zhao explained.

"Oh, then this is a good thing, the case is solved, and the school can also give an explanation to the society" Yang Shi heard this first, and probably learned of Zhao Zhongzheng's intention, "Presumably you came this time to need the school to cooperate with the investigation, right?" Rest assured, we will fully cooperate. ”

"Principal Yang is really smart, and he really needs the help of the school."

"Director Zhao has won the award, I don't know what specific help I need?"

"That's right, Principal Yang, now there are clues that the girl's disappearance may be related to the old campus of your school, but there are strict controls set up there, and outsiders are not allowed to enter and exit at will, which is a big obstacle to our case."

"What!" Hearing that it was related to the old campus, Yang Shixian was a little shocked, and after thinking for a while, he said: "That's the case, Director Zhao, you should know a little about the creation of the world, right?" ”

Not long ago, he personally killed a mutant, and Zhao Zhongzheng naturally knew something about the creation, so he nodded.

Seeing Zhao Zhongzheng nodding, Yang Shi said again: "The old campus is divided into creation, and the order is directly issued from above," he pointed to the top as he spoke.

It turned out to be related to the creation of the world, Zhao Zhongzheng had a premonition in his heart at the moment, it seems that this disappearance case is far from being as simple as he thought.

"Since that's the case, then I'll apply to the above first" Zhao Zhongzheng understood that this was no longer something that the principal in front of him could decide, so he got up and retired.

Back in the police force, Zhao Zhongzheng tried his best to explain the matter to his superiors, who asked the person in charge of Base No. 4 and learned that it had nothing to do with them, so they were allowed to enter the investigation, but those who entered the old campus had to sign a confidentiality agreement.

With the permission of his superiors, Zhao Zhongzheng took Chen Nan and returned to the school again, and got a map of the old school district from the school.

The map of the old campus is very detailed, but in the map, there are several areas that are obscured by shadows, and the person who sent the map told them that these areas are absolutely off-limits.

The three of them waited hard, and were about to call to inquire when there was a noise at the door of the warehouse, and Chenxing immediately went to open the door.

Seeing that there was one more person, Chenxing smiled politely at Chen Nan and nodded, and invited the two into the house.

Fei Fei brewed a few cups of coffee, and when everyone was ready, she served them separately.

Zhang Chu couldn't wait to ask, "Team Zhao, how is it?" ”

Zhao Zhongzheng smiled slyly and said, "You first tell me how you determined that Shen Meng's disappearance was related to the old campus, and then I will tell you the result." ”

"Team Zhao, don't play with me" Zhang Chu was a little embarrassed, he didn't expect this guy to remember it.

"Haha, everything is going well, this is the map of the old campus, now you can enter" Zhao Zhongzheng said as he spread out the map on the table.

"Sure enough, it was Team Zhao, a top two" Zhang Chu saw that it was successful, and patted Zhao Zhongzheng's fart a little.

"Don't be too happy, although you can enter, there are still requirements."

"Oh, what request?" This made Chenxing feel a little surprised, but he didn't expect that there would be additional conditions.

"Oh, do you see these shaded areas" Zhao Zhongzheng pointed his finger at the shadowed places on the dot map.

"Well, see, why are these places shaded?" The crowd was puzzled.

"These areas, which involve state secrets, are absolutely not allowed to enter," Zhao explained.

"State secrets?" The three of them repeated in unison.

"Yes, how powerful the biology department of Qingyun University is, you don't need me to explain it to you, there are important experiments on the old campus, which are kept secret from the outside world."

Hearing Zhao Zhongzheng say this, the three of them understood, but they didn't know that Shen Meng's disappearance was due to the experiment there.

Because there was no sufficient evidence and he didn't want to attract attention, Zhao Zhongzheng decided that he and Chen Nan would take the three of them to investigate.

It was getting late, and the five of them agreed to gather here early the next morning.

There was nothing to say all night, and early in the morning of the next night, the three of Chenxing waited for Zhao Zhongzheng and Chen Nan in the secret base early.

Zhang Chu was extremely excited, and said with his hands in full swing: "It's exciting to think about it, this is more exciting than exploration, a state secret." ”

Fei Fei seems to be quiet on the outside, but in fact she is eccentric, which can also be seen from her love of adventure.

"I heard all kinds of rumors about the old campus early in the morning, and today I can finally go to the field to see it" Fei Fei also looked very excited.

Seeing the two of them like this, Chen Xing couldn't help but remind: "When you get inside, you must pay attention to safety." ”

As soon as the words fell, Zhao Zhongzheng and Chen Nan arrived.

The five of them met, exchanged a few words, and walked to the old campus.

There is only an iron gate between the old and new campuses, and although this door is not open all year round, there are always people on duty.

When they arrived at the gate, Zhao Zhongzheng showed the pass specially approved by the school, and the five of them successfully stepped into the old campus.

The old campus is built on the mountain, and it truly achieves the unity of nature and man.

The entire campus is surrounded by forests, because no one has walked for a long time, some weeds have grown on the road, and the trees on both sides of the road are also lush because they are not pruned, covering the sky, and only some sunlight shines through the gaps between the branches.

All sorts of unnamed birds hid in the bushes and chirped, and even the five of them were startled by the sudden emergence of a hare.

If the new campus represents contemporary innovation and technology, then the old campus represents the simplicity and depth of the ivory tower.

As they walked, they sighed that the impact of human beings on nature is so great, and the two campuses separated by just one wall are like two worlds.

After sighing, Zhao Zhongzheng took out the map and began to discuss the route with everyone, after all, the old campus is not small, and there is no need to go to the shaded area.

The old campus is the central distribution pattern, the comprehensive administrative area is in the center, the rest of the departments are distributed around it, and the shaded area is mostly located in the area where the biology department is located.

Therefore, the route planned by everyone is similar to O-shape, only in the biology department, you need to make a detour.

Walking along the main road, a huge horizontal plaque appeared in front of me, which was made of a very old arched tree, and only four big characters were engraved on it: Qingyun University.

Behind the plaque, the road is divided into three, directly in front of which leads to the general administrative district, on the left, to the Faculty of Literature, and on the right, to the Faculty of Mathematics.

Several people decided to start their search with the literature department on the far left.
