Cheng Jiayi and the three of them stepped back and looked up, still screaming.

"Hurry up, he's mutated!" The armed policeman who fell to the ground struggled, but was unable to get up.

At the gate of the staircase, the armed policeman, who was also dressed in black, hesitated, turned around and pounced on the two people lying next to the door.

"Let's go." The people on the ground suddenly coughed up blood, and Du Yiyi didn't know where the power erupted, so he ran down with his back. Cheng Jiayi stretched out his hand to help the armed policeman who fell to the ground, and when his eyes met, he saw that the eyes of the armed policeman suddenly changed.

Not only his eyes, but his cheeks hugging outside suddenly shrank, and his body suddenly deflated a little in the thick armed police uniform.

The words that were still said suddenly appeared in Cheng Jiayi's mind: this armed policeman was infected, and his own energy was being rapidly metabolized.

The armed police suddenly moved-he couldn't move, but suddenly he seemed to have strength again, as if he was about to pounce on Cheng Jiayi. Cheng Jiayi's outstretched hand shrank, and out of the corner of his eye, he saw the submachine gun underground.

She didn't know why she grabbed the gun, but she did. The heavy submachine gun woke her up suddenly, and she grabbed the gun and ran reflexively.

The whole building seemed to be full of chaotic sounds, and they rushed to the first floor, only to hear the last screams from the hall outside.

The three of them were all frightened, Du Yiyi's legs were already weak, panting heavily, Cheng Jiayi only felt that her mind was still full of excitement and fear, she knew that she could still control herself, but she didn't know how long she could control it.

She was so hungry for blood, she wanted to pounce on it when she smelled it.

She hurriedly took off her backpack, only to see that she was still holding a submachine gun, half-kneeling on the ground and throwing down the gun, grabbing her backpack, opening the water bottle, and taking several big sips.

The entry of sugar calmed the bloodthirsty thoughts in her body a little, and she grabbed another bag of compressed biscuits and tore them open.

"One by one, you also drink and eat." Still urging, he reached out and grabbed the compressed biscuits from his bag.

Cheng Jiayi swallowed the biscuit vigorously, Du Yiyi took two big sips by himself, handed it to Yi, and also pulled the compressed biscuit. Cheng Jiayi closed the backpack and threw it behind her, and suddenly found that she didn't know when, she threw away the fruit knife.

"What are we going to do?" Du Yiyi asked in a low voice.

There was still howling upstairs, and the hall on the first floor seemed quiet. Cheng Jiayi grabbed the gun and stood up.

She couldn't shoot, but she had this one as a weapon.

Cheng Jiayi touched the door and slowly, slowly pushed a door open a small crack. The smell of blood is even stronger.

The body blocking the elevator door is gone. The armed police in the hall were also gone. There was no one in sight.

But the smell of blood is so strong.

Suddenly, she saw a pair of feet on the side of the shopping guide with black boots on them.

Armed police?

She pushed the door open a little more.

The head slowly peeked out from the shopping desk, and then a man in a white lab coat stood sideways at the staircase.

His snow-white coat was spotless, clean, and there was not a trace of blood.

He reached out and took out a wrapped gauze in the pocket of his white coat and wiped the corners of his mouth, and Cheng Jiayi saw that he still had a stethoscope around his neck.

Then the man looked around slowly.

Cheng Jiayi closed the door instantly, and her heart almost jumped out.

Cannibals still have reason! Cannibals are doctors!

She turned her head to look at the still, who else could she trust?

The footsteps slowly approached, and Cheng Jiayi grabbed the gun and retreated. They have no way to escape.

The door was slowly pushed open, Cheng Jiayi fell back to the wall, and it was only three or four steps away from the gate, she wanted to stand up, but she couldn't stand up at all.

"Dr. Zhao." Still exclaimed in surprise.

"Professor Yi, you're here." Dr. Zhao quickly glanced down the stairs with a concerned expression, "What's wrong with you?" Just as he was about to step forward, he saw Cheng Jiayi holding a gun, and the muzzle of the black hole was facing him, so he immediately stood down.

"My foot twisted. How's it going out there? I was still relieved to see my familiar colleagues.

"There was no one on the ground floor, nothing was wrong. Upstairs messing up again? Doctor Zhao looked away and looked at the still, "I'll show you your feet." ”

Saying that, he stepped forward.

"Stop!" Cheng Jiayi screamed, "Stop! Get out of here now! Right away! Or I'll shoot! ”

Doctor Zhao stood still, still surprised, and turned to Cheng Jiayi and said, "Jiayi, this is Uncle Zhao, Auntie's colleague." ”

Cheng Jiayi's mind was full of the black shoes just now, and the orderly movement of wiping the blood from the corners of her mouth.

"Leave! I don't believe anyone! Let's go! Cheng Jiayi shouted, her hands trembling.

If she could be sure that there were bullets in the gun and that the gun was loaded, she would not hesitate to shoot. Compared to those mutants who have lost their minds, those with sanity are still bloodthirsty.

"Kid, I'm a doctor, Professor Yi has a sprain, you have to let me show her." Dr. Zhao looked at Cheng Jiayi gently, and then took a step forward.

Cheng Jiayi raised the muzzle of the gun and pointed it at Dr. Zhao, her finger on the trigger.

She knew that murderous intent appeared on her face.

Dr. Zhao slowly took another step forward, his hands slightly raised, as if to fall to appease.

"Jiayi, don't be impulsive." Still softly.

Cheng Jiayi looked into Dr. Zhao's eyes and looked at him as one step away.

The quivering muzzle of the gun almost touched Dr. Zhao's white coat, and she saw a flash of pride in Dr. Zhao's eyes.

"Don't ......," Dr. Zhao's hands moved slightly.

"Bang bang bang!" The strong recoil force made Cheng Jiayi's body shrink, and Dr. Zhao's body suddenly slammed forward, he seemed to look at the smoking muzzle in disbelief, his face suddenly turned hideous, and he threw himself at Cheng Jiayi with his hands wide open.

A stone's throw away. Cheng Jiayi raised the muzzle of the gun and blocked it forward.

The moment before Dr. Zhao threw himself on the muzzle, he lost his strength, hung on the muzzle, and fell to the ground with the gun.

Jiayi ...... You ......" still looked at Cheng Jiayi in disbelief, and raised himself to see Dr. Zhao.

"I saw him eating people." Cheng Jiayi shuddered.

"What? How can it be? His mouth was still open, as if he couldn't breathe.

"He ate an armed policeman." Cheng Jiayi shuddered and pursed her lips.

Only she knew how strong her will was to resist the temptation of the blood before her—the blood of this man was sweeter.

"Mom, let's go, let's go." Du Yi squatted halfway, holding still.

Cheng Jiayi also got up and glanced at Dr. Zhao reluctantly.

"Guns. Jiayi, gun! Du Yiyi reminded.

Cheng Jiayi came to her senses, pulled out her gun from under Dr. Zhao, and pushed the door open.

It was empty outside, as if the riot had never happened, and she looked around blankly.

Outside the building was a black hole in the night, and there seemed to be more danger lurking in the darkness than the lights inside the building.

"Where are we going?" Du Yiyi said in panic.
