Su Yu stopped, put his hand on the iron door, and pushed hard.

The iron door remained untouched, and every lock was so quiet that it was as if it had never been opened.

"What's wrong?" Chu Wei, who noticed Su Yu's movements, instantly turned around and aimed the gun in his hand at this side.

"This door, this door was just opened." Su Yu replied back.

Chu Wei didn't come over, he put his finger to his lips and made a silent gesture to Su Yu.

Su Yu instantly understood that if that zombie had entered this door, then the danger they were in now was far more than just a zombie.

No one dared to say anything behind that door, and it was estimated that they would not be able to get any benefit from Su Yu with their bare hands and Chu Wei, who only had a pistol.

Su Yu took back the hand that was placed on the iron door and took a few steps to keep up with Chu Wei.

The two got on the elevator and pressed the button on the first floor.

It wasn't until the moment the elevator door closed that Su Yu let out a long breath.

……

By the time the academy had sorted out Song Zaihu's body and lifted it out of the basement, it was already eleven o'clock in the evening.

Although he had been eaten to the decent, the academy still sent a special ambulance.

When several detachments of the Raiders opened the mysterious iron door, they found that it was only a large abandoned laboratory.

Although there was no dust all over the place, it did not leave a trace of useful clues. It can be seen that even if there were any unsavory secrets, they were eliminated in the time that Chu Wei contacted and supported.

While waiting, Chu Wei explained to Su Yu why he came here.

"It was Song Zaihu who sent a message to me to come over, he said that he felt that he was in some danger, and there were not many people who could be trusted, so he asked me to come over and help him."

It seems that in Song Zaihu's eyes, Chu Wei is a person who can be trusted in the academy, and Su Yu asked him:

"Teacher Chu, didn't Teacher Song tell you what happened?"

"No, he only sent one message." Chu Wei inserted the pistol back into the pouch on his waist and raised his head: "Why are you here?" ”

Su Yu thought about it, directly opened the hand screen, and showed him the news of Song Zaihu.

"That zombie is not simple...... Chu Wei wanted to speak again.

"Teacher Chu," Su Yu called Chu Wei, but was silent again.

She recalled what Song Zaihu said and asked her not to tell others about these strange things. But now that Song Zaihu has paid the price of his life because of these secrets, he must have known some ulterior things, and someone wants him to shut up directly.

It is impossible for Su Yu to let this matter be covered up, but it is impossible to reveal the truth by her own strength.

And Chu Wei has enough strength to investigate this matter. In Su Yu's subconscious, he is also the only person he can trust now.

"What's wrong?" Chu Wei saw that Su Yu shouted to himself but did not follow, and waited for a moment to ask.

Su Yu made up his mind and told him everything one by one. Including the red-eyed zombie who attacked Hu Yue, the goat pupil zombie in the domestication base, and Song Zaihu and all the things she said.

Chu Wei listened attentively, and gradually frowned, until Su Yu finished talking about everything, he was still in deep thought.

The late-night style was cold, and Su Yu shivered, and she crossed her arms to wrap the coat on her body.

Chu Wei turned his head to look at her, his frowning brows relaxed, and admonished:

"I'll check these things, whether you're in class or doing other things these days, try not to be alone. You don't know much, so it shouldn't be too dangerous. ”

Su Yu nodded in response: "But Teacher Chu, if they can kill Teacher Song for that secret, they can ......."

"I know," Chu Wei interrupted her, knowing that Su Yu was worried about his safety, he smiled rarely: "Don't worry, it's much harder to shut me up." ”

He opened his hand screen and stretched out to Su Yu: "This is my contact information, you can call me if you have something." ”

Su Yu saved Chu Wei's phone into the hand screen, watched him turn around and follow the doctor into the ambulance.

That figure gave her inexplicable peace of mind.

Su Yu lowered his head and looked at the phone number on the handscreen again.

……

Hao Tian's messages were sent one after another, and the phone calls were made one after another, Su Yu was in a state of high tension, and he muted his hand screen again, and he never saw it.

In the end, she called directly:

"What's wrong? We came to the domestication base to look for you, and you are not here. ”

Su Yu was surprised that because of her loss of contact, Hao Tian actually called Zheng Wang and Zhao Dacheng up in the middle of the night to find her.

A warmth welled up in her heart.

"If you don't go back to the dormitory in the middle of the night, you will scare me to death, I will call Teacher Song to report that you are missing."

"Teacher Song is dead." Su Yu said.

Such a big thing happened in the academy, and she didn't plan to hide it from them anymore.

"What?!" Hao Tian's shocked voice came from the other end of the phone.

"I'm at the Biological Research Center, let's find a place to meet, and I'll explain it to you." Su Yu said, her voice was already calm at this time.

"Okay, let's meet in front of the school building."

"Okay."

The spherical building is located in the center of the college, making it the best choice no matter which way it comes from.

At this time, there were not many campus buses in the college, and Su Yu walked several stops to get on the bus.

When they arrived at the square of the school building, the three of them were already waiting for her there. But there was really nowhere to go in the academy at such a late hour, so they listened to Su Yu talk about everything that had happened recently in the square with a cold breeze.

I have already told Chu Wei just now, Su Yu didn't have any waves in her heart when she said it this time, and the language description was more accurate and concise, but when she told about seeing Song Zaihu's corpse, she omitted those unacceptable bloody scenes.

"Teacher Song is too miserable." Zheng Wang still let out such an exclamation.

Hao Tian listened carefully and didn't say a word, but Zhao Dacheng opened his mouth and asked, "So, you don't know what Teacher Song knows before they kill him?" ”

Su Yu shook his head: "I only saw his body today, and I can only guess that it is related to the investigation of the red-eyed zombie." He must have found out something before he was killed. ”

"There are many ways to kill the mouth, why manipulate zombies to kill people?" Hao Tian, who had been silent for a long time, opened his mouth to ask.

yes, why in such a cruel and eye-catching way.

Zhao Dacheng propped his chin and said a possibility: "Do you think that from the time Teacher Hu was attacked by zombies to Teacher Song who was killed by zombies, both times seemed like a test?" ”

"Testing?" The other three didn't quite understand.

"If, as Su Yu said, Mr. Hu's incident proves that zombies have sight and angry feelings, and Mr. Song here, it proves that zombies can be driven by whistles." Zhao Dacheng said.

"So, it's a progressive test."
