In a chemistry laboratory with many instruments.

"Uh-uh-" Chen Ruoxi covered the wound on her forehead, grinning in pain, and her mind was a little confused.

Although she didn't participate in the battle, Fang Yitian's force when she pushed her downstairs was not small, and directly let her roll under several steps, and now she not only had unbearable pain in her body, but even her forehead was broken.

"Are you alright?" Seeing this, Fang Yitian didn't delay much, and immediately took out the medical supplies and a towel in his backpack, preparing to bandage Chen Ruoxi's wounds.

"It's okay...... Ahh Woo, woo! Because Fang Yitian's technique was not very professional, when he wiped the wound with a cotton swab, Chen Ruoxi almost screamed in pain, and he had expected it, so he specially took a towel, ready to block Chen Ruoxi's mouth at any time.

Rubbing the wound is such a big reaction, I really don't know what it will be like if I use alcohol. Fang Yitian secretly scolded himself.

After a simple bandage, Chen Ruoxi was a little more sober than before, but because of the severe pain, her physical exertion was also a little large, so she unconsciously fell into Fang Yitian's arms, her face was flushed, and her chest rose and fell sharply.

In this regard, Fang Yitian packed up his things without squinting, looking like he had no worldly desires.

But the slightly disorganized rhythm of his breathing betrayed him.

It didn't take long for Chen Ruoxi and Fang Yitian to recover temporarily—the injuries suffered by the two were only minor.

Fang Yitian came to the window of the front door of the laboratory, quietly opened the window a little, and looked out of the laboratory with the only gap.

Now the zombies have calmed down a lot, but most of them are still lingering outside the door and haven't walked away.

"Gotta figure figure out." Fang Yitian retracted his gaze and looked around.

Soon, he found a breakthrough.

The lab is on the far edge of the second floor, with only one classroom next to it and air on the other.

He remembered the way he had first walked out of his house, which was a chemistry lab with as much glass as he needed.

He took the bundle of rope out of his bag, picked a bunch of glass instruments and tied them together, and then came to the window again.

Only this time, he was in front of the window closest to the back door.

He opened the window little by little, and did not stop until the hole was large enough for him to exert enough force.

After slowly sticking the glass instrument out of the window, Fang Yitian took a deep breath and quickly swung the glass instrument with the help of a skillful force.

With the sound of "ping pong", Fang Yitian raised the glass instrument to an ideal height in just one moment, and then he took advantage of the opportunity of the change in strength to throw the glass instrument out.

As soon as he finished throwing it, Fang Yitian withdrew his hand as if he had been electrocuted, and the speed was so fast that it was no more than a blink of an eye.

As early as when the glass instrument began to "ping pong", the zombies on the other side of the front door heard the sound, and if Fang Yitian stopped at night, it was estimated that he would have to say goodbye to his partner who had been with him for many years.

"Bang!"

"Ping-Pong-"

The sound of the glass instrument breaking is not very loud, but it is better than the sharp, and it is more obvious when you hear it in the ear.

It should be the same for zombies, I saw that those zombies roared when they heard the sound of glass breaking, and jumped down the stairs one after another without fear of death.

After the movement outside the door disappeared, Fang Yitian slowly opened the door, cautiously stretched out his head to watch for a while, and did not see a single zombie.

He pushed the door open lightly, and only after expanding his field of vision completely did he make sure that there was no danger outside the door, and only then did he bring Chen Ruoxi out.

"Let's go, let's start on the second floor." Although Fang Yitian was willing to help Chen Ruoxi find someone, he still didn't want to waste more time, so he got down to business as soon as he got out of danger.

"Hmm...... Well! Chen Ruoxi responded a little unnaturally.

She was a little worried, if Fang Yitian knew that he had deceived him, would he do something terrible......

……

Fourth floor.

Ye Maimai sat and leaned against the space under the podium table, his face a little sallow and semi-unconscious.

She had been living on sugars and distilled water in the lab all these days, and she could barely maintain her condition, but after a long time, problems arose.

Now she can't lift her energy, she feels light and limp, and sometimes she can't see anything even when she opens her eyes.

"Am I going to be planted here?" Ye Maimai silently asked himself in the bottom of his heart.

"If it weren't for that long-tongued monster outside the door, I wouldn't be trapped here!" Ye Maimai thought angrily, she was in a hurry now, she wanted to get rid of that monster as soon as possible, and she wanted to fly out of the window directly.

"Bang bang bang!" Suddenly, a voice that was quite familiar to her sounded, but limited to her own state, the voice was very faint and faint in Ye Maimai's ears.

It wasn't until the second time he heard it that Ye Maimai couldn't tell what it was.

Gunshot!

There are gunshots!

Ye Maimai heard the human tracks, and his spirit suddenly perked, and his consciousness began to gradually return to his body.

She barely stood up, climbed hand to hand on the edge of the window, and with the last of her strength rested her head on the edge of the window.

But she didn't see anyone.

"What......" Ye Maimai thought a little bitterly, "It's an illusion......"

As soon as the thought fell, she could no longer support her body, and simply fell to the ground neatly.

"Xixi...... Sorry ......"

……

Fang Yitian and Chen Ruoxi quickly searched the third floor, and soon came to the fourth floor.

But the scene on the fourth floor surprised both of them.

I saw that on the wall on the fourth floor, small holes that were clearly visible were printed on the original gray-white wall, but the strange thing was that the distribution of those small holes stopped outside the door of the second laboratory, and the farthest away from Fang Yitian and Chen Ruoxi also happened to be a small hole printed on the door of the second laboratory.

Because the door to the lab was made of steel, the hole was pitifully small compared to the others, the size of a mung bean.

Fang Yitian and Chen Ruoxi stood outside the door and looked at each other silently, both having a premonition in their hearts.

Then Chen Ruoxi couldn't wait to open the door, but the door was locked from the inside, and she couldn't open it.

"Don't worry, let me come." Fang Yitian gently pulled her back, then took out some strange tools from his bag, picked out two of them, and leaned over to operate.

"Uh, you're ...... Lockpicking? Chen Ruoxi asked in some surprise. She knew that Fang Yitian was very powerful and knew a lot of things, but she never thought that Fang Yitian could even pick a lock.

"When I was a child, my grandmother was forgetful and often lost the keys to the house, and my grandfather couldn't learn this kind of thing when he was old, so I had to do it~" Fang Yitian explained in a relaxed tone, and after explaining, the door also opened.

Chen Ruoxi watched the door panel rotate indoors, and the expectation in her heart was a little uncontrollable.

"Yezi, you must be here!"
