Xu Luo pulled Xia Yujia and went straight to the direction of the teaching building.

The laboratory is located on the fourth floor of the academic building.

At dusk, there are more people on campus than usual.

"Ahem."

The continuous coughing sound sounded around the two of them, and Xu Luo's cold face showed a trace of anxiety, and he pulled Xia Yujia behind him.

A professor of some age was in front of Xu Luo, covering his mouth with one hand, his eyes were red, and his face was blue.

"Professor Zhang?" Xia Yujia said with concern, "Are you uncomfortable?" Would you like us to help? ”

Professor Zhang raised his head, glanced at Xu Luo, and suddenly said: "Xu Luo and Xiao Xia, they are in love, I have nothing to do, but my throat is a little uncomfortable, you are busy, continue to talk." ”

Xia Yujia's cheeks instantly turned red.

Xu Luo's face remained unchanged, but there was a trace of regret in his eyes.

He knew better than anyone that the virus had begun to spread, and that was the first symptom of infection.

This has nothing to do with physique, until Xu Luo's dying era, I didn't know how this virus came into being and why it spread.

However, this is just the beginning, and when the first zombies appear, it will really spread, and unsuspecting people will form an explosive spread after being bitten by zombies.

"Xu Luo, it's really good, Xiao Xia is the goddess of our school." Professor Zhang gave a thumbs up.

Xu Luo didn't know what to say, and a trace of gloom replaced the regret in his eyes.

"Professor Zhang!"

Xia Yujia stomped her feet.

"Huh." Professor Zhang smiled, "I'm fine, you're busy." ”

After speaking, he walked to the cafeteria.

Xu Luo sighed secretly, tightened his hands, and pulled Xia Yujia to continue walking.

Xia Yujia glanced at him and said softly, "... It's all your ......."

Feeling the temperature of Xia Yujia's jade hand, Xu Luo couldn't help but feel a wave in his heart, and for the first time felt emotions that he had never felt before he was reborn.

-- Maybe that's the influence of another soul.

Time is running out.

In the flow of people passing by, there was an intermittent coughing sound.

This sound came to Xu Luo's ears like the second reading of a clock, making his heart become anxious again.

He had to get into the lab before the outbreak, and now he had to be there to buy him time.

The last afterglow dissipated, the sky darkened instantly, and Xu Luo pulled Xia Yujia to the front of the teaching building.

Three minutes to go.

Glancing at a tender green grass surging out from under a piece of gravel beside him, Xu Luo Huoran raised his head and said in a deep voice: "Go upstairs and take the stairs." ”

Xia Yujia's mood was still immersed in charm, and she gently let out an "um" sound from her nose.

Xu Luo took Xia Yujia's hand and strode towards the building.

Firm footsteps.

The lights hadn't been lit yet, and the hallway was a little dim.

It wasn't time for classes, the building was silent, save for the footsteps of two people going upstairs.

Xia Yujia's head hung lower, the teaching building at this time had a legend of the best place in love, and she knew that there might be a couple of lovers hiding in countless invisible corners.

However, Xu Luo seemed to be bolder than all of them, and even thought of going to the laboratory.

It must have been on purpose, because he knew he had the key.

Thinking of this, her cheeks became even hotter, and she glanced at Xu Luo again.

Xu Luo's face was very serious.

- False seriousness! Bad apple.

In Xia Yujia's apprehensive feelings, the two had already walked to the corner of the third to fourth floors.

A sound of uh-huh-hmmmm came into the ears of the two of them.

A pair of lovers were hugging each other tightly, and the sound came from the woman's nose, very engaged.

Xia Yujia hurriedly lowered her head, not daring to take a second look.

The heart beats even more violently.

Xu Luo didn't change at all, and pulled Xia Yujia straight over, and the man just opened his eyes and glanced at them, and then continued his behavior just now.

In his heart, he just thought that Xu Luo and the others were also looking for a place.

It's only two minutes.

When he came to the fourth floor, he pushed open the somewhat heavy corridor door, and took a few steps forward, Xu Luo suddenly stopped.

Let go of Xia Yujia's jade hand, and hit his right elbow heavily on the eye-catching 119 glass window next to the corridor, and the sound of glass breaking was like a loud thunder in the silent building.

Xia Yujia looked at Xu Luo in surprise and reached out to take out the fire axe from the window.

- What does he want to do?

The lovers who were immersed in the lingering in the building were also shocked by this loud noise, and they all stopped their lingering movements and listened attentively.

After a while, no other sound came out, and they all thought it was just a very accidental accident, and resumed the act that had been interrupted.

"I forgot, you should have the key."

Xu Luo looked at Xia Yujia awkwardly and made a wrong explanation for what he had just done.

If Xia Yujia hadn't been immersed in disordered emotions at the moment, she would definitely not believe this explanation. It's just that now she only has a sense of relief, and then she gave him a fierce look.

Xu Luo didn't want her to think more, now for him, every second of time is extremely precious, so he winked at her and said softly: "Run, beware of someone coming." ”

grabbed Xia Yujia's hand and ran to the laboratory.

Although rebirth gave him an idea of what would happen next, he was no longer a third-order enhancer before he was reborn.

He had to prepare weapons for himself in advance.

There is only one minute left.

Coming to the door of the laboratory, Xu Luo urged: "Hurry up." ”

Xia Yujia was embarrassed, but slowly took out the key, and said like a mosquito chirping in her mouth: "What's the hurry!" ”

Fifty seconds remaining.

She inserted the key into the keyhole, but it slipped again and again, and she noticed that her hands were shaking.

Xu Luo was really anxious.

However, he didn't blame Xia Yujia, he just stretched out his hand and held her weak jade hand.

Feeling the warmth of Xu Luo's hands, her trembling hands stabilized, but her body was a little soft, and her earlobes were hot.

took the key from Xia Yujia and inserted the key into the lock hole.

Thirty seconds remaining.

One twist.

Didn't open it!

The door was locked.

Xu Luo's heart instantly cooled, and he shouted: "Who is inside?" ”

No one answered.

Xu Luo slammed his foot on the door, and there was a "bang".

"Open the door! If you don't open the door again, you'll rush to the door later. Xu Luo yelled.

Twenty seconds.

"Don't! It's coming, it's coming. ”

There was a hurried sound from inside the door, followed by the sound of tables and chairs moving.

Ten seconds.

Footsteps came-

"Click" -

The door opened, and a man with a dark face and blood-red eyes appeared in the doorway. The man's resentful look could be clearly felt.

Five seconds to go.

Xu Luo didn't think about it, grabbed the shirt on the man's chest, fiercely pulled the man out of the laboratory, and then pushed Xia Yujia into the laboratory.

Then he kicked the man away, dodging himself into the laboratory.

Three seconds.

He closed the door with his backhand, and then pulled down a cabinet he saw and straddled it behind the door, blocking it.

One second.

Here we go.

It was completely dark, and the lab was dark.

A terrible scream came, which was particularly thrilling.

Xu Luo let out a long breath.

Xia Yujia was completely stunned, at a loss, she didn't know what was going on.

Xu Luo's violent behavior just now had already shocked her, and she suddenly felt that Xu Luo in front of her was really completely different from the past.

"Hurry up, don't be stunned, find something to block the door." Xu Luo urged.

Then, regardless of Xia Yujia's reaction, he began to look for heavy items and drag them behind the door.

Xia Yujia said blankly: "Why? ”

Xu Luo didn't look at her either, just dragged a long table wrapped in iron behind the door: "Look outside the door yourself." ”

Xia Yujia looked out through the small window on the door of the laboratory.

His face was full of shock, and his face instantly turned pale.

An almost unimaginable situation appeared before her eyes.

The man who was kicked down by Xu Luo just now was slowly getting up, and he was completely inhuman, and he had become a zombie that only appeared in the movie that she had only watched at the beginning and would never watch again.

Xia Yujia clutched her chest and stepped back again and again.

"No way, no way, I'm dreaming."

As he spoke, he put his right hand to his mouth and prepared to take a bite.

"Don't bite." Xu Luo scolded.

Xia Yujia was stunned again, at a loss.

"You must remember that you must not be bitten by zombies, nor can you be scratched by zombie fingernails, otherwise, you will also become a zombie."

Xu Luo said quietly.

Xia Yujia just nodded again and again, at this time, even if she was holding the taekwondo black belt level of the fourth grade, she only nodded mechanically, and she didn't know what to do.

She didn't realize that she was not a zombie herself.

"Okay, don't be stunned, hurry up and help me block the door."

Xu Luo didn't stop, and at this time he had blocked the iron table behind the door.

Xia Yujia came to her senses, although she still didn't believe what she had just seen, she still knew what to do at the moment of crisis.

Working together, the two began dragging any heavy objects they could move behind the door.

At the beginning of the virus outbreak, the zombie moved very slowly, and the zombie did not move to the door of the laboratory until this moment and began to bang on the door.

It's just that zombies who have lost their minds have no eyesight, and can only rely on an instinctive feeling to find a target.

When Xu Luo and the others finished blocking the door and stood still, the zombie seemed to have lost its target, and instead turned a girl who ran to the fourth floor with a scream into a target.

The early zombies seemed to be particularly sensitive to the screams of fear from humans.

Moving with staggering steps, he clumsily walked towards her.

Xia Yujia suddenly leaned in front of Xu Luo and asked cautiously, "Now, what should we do?" ”

A smile appeared on Xu Luo's face, but there was some coldness in the dark.

"Make makeup potions and get ready to participate in this makeup feast."

There was silence in the dark laboratory, and both could hear each other's heartbeats.

Suddenly, a thought sprung up in the hearts of both of them at the same time.

- What is the man who turned into a zombie doing in the laboratory? Alone? Someone in the lab? Why is there no sound?

Could it be ......
