The situation outside is getting worse, and the city is close to paralysis.

Cars were piled up on the road, shops along the street were in shambles, and the streets were littered with mutilated bodies and scattered internal organs.

Xiaocao drove the car carefully to avoid pressing those disgusting things, but fortunately, Meimei's beautiful children's voice commanded the route to relieve Xiaocao's discomfort.

The area around the Biological Research Institute was surprisingly quiet, maybe the zombies didn't like the smell here, and none of them were dangling at the door.

The door of the research institute was closed silently, and a few little guys didn't dare to make too much noise, so they carefully patted for a long time without moving, and they all sat on the spot in frustration.

"Sister, it seems that there is no one inside, we ran for nothing. ”

Looking at her brother's aggrieved expression, Xiaocao smiled, she pointed to the camera above and motioned for a few children to look over.

"Somebody looks at us, keep smiling, kids. ”

Bai Xiaoqi jumped up all of a sudden, waved his hands at the camera swaying from side to side, and said in a low voice: "Open the door! We are all good people! Hurry up and open the door!"

No matter how he shouted, the gate did not move, and there was no movement inside.

Xiaocao glanced at the camera, picked up a pile of stones from the flower bed, picked up one and slammed it in his hand, and slammed it towards the door.

The fist-sized stone made a beautiful arc in the air, and it made an alarmingly loud sound when it hit the door.

"Sister Bai, this door is made of stainless steel and concrete, you can't smash it. Xiao Siyan said puzzled.

"Sister, you'll lure zombies over!" Bai Xiaoqi was taken aback by his sister's actions.

Xiaocao didn't say anything, picked up another stone and threw it at it.

Watching the grass throw stones over one by one, smashing the gate with a buzzing sound, without the slightest intention of stopping, the two boys looked at each other.

"Is your sister crazy?" asked Four-Eyed quietly.

"Your sister is crazy!" Although Bai Xiaoqi was puzzled, he didn't allow others to say a bad word about Xiaocao.

"Meimei, what do you think?" Xiao Siyan raised his hand in surrender and turned to look at Meimei.

The little girl looked pensive, "Maybe my sister is just going to lure the zombies over?"

"What did you say?"

Mei Mei showed an excited expression on her face, clapped her hands and said, "Yes, we just want to lure the zombies over!"

After saying this, Mei Mei picked up a stone and smashed it at the gate like a little grass.

Xiaocao looked at the smart little girl, and the two looked at each other and smiled, and together they began to throw stones.

Looking at the movements of the two and the rapidly swaying camera, the two boys seemed to understand a little.

"They're here to show the people inside, right? Is that just a threat?"

"The ancients, salute first and then soldiers, we have saluted for so long, it's time to give them some color!"

The four of them smashed for a while, and the door finally opened a gap, and two men in full protective clothing cautiously walked out from inside, scanning and inspecting the two of them, and then brought a few people in.

Along the way, Xiaocao saw many instruments, test tubes, but did not see many people, it was empty and silent, which was unsettling.

"You little guys, why don't you go home and hang out outside?"

When a loud voice sounded, Xiaocao was looking at a huge machine, wondering if it could be the "light of the end times".

"Santa Claus!" Bai Xiaoqi blurted out.

Xiaocao looked back and saw a chubby old man, with white hair and red face, wearing a red sportswear, really looking like Santa Claus.

"Santa Claus doesn't exist. Xiao Siyan corrected seriously.

"It's still a quiet little girl," Santa Claus looked at Mei Mei and said, "Hello, little girl, I'm Dr. Ji, what's your name?"

"Dr. Ji, Dr. Jixiang?" Xiaocao's eyes widened suddenly.

"Yo, this little girl knows me?" said Dr. Ji, with a smug expression.

The original owner had never met Dr. Ji, but he had heard the name too many times.

The most powerful base in the late apocalypse is the City of God, and the reason why the latecomers are superior and unrivaled is because all the members of this base are supernatural.

This is not a coincidence, let alone luck, but because someone has mastered the method of transforming ordinary people into supernatural beings.

Bioactive vaccines, coupled with the assistance of instruments, can promote the mutation of ordinary people and induce mutations in abnormal genes, thereby greatly increasing the probability of transformation.

And the person who invented this technology is Dr. Jixiang.

The original owner had heard this name many times in the base, and everyone talked about him with awe and yearning, and at that time the original owner wanted to have the opportunity to meet Dr. Ji.

She would desperately beg him to give her a chance to be born again.

"Dr. Ji, where are you in the development of your vaccine?" Xiaocao asked with the original owner and his own expectations, unable to wait a second longer.

"Hey, you actually know my research direction?" Dr. Ji's eyes widened, he looked Xiaocao up and down, and grinned, "I'm so well-known?"

"Is there really a vaccine?" Bai Xiaoqi was excited, "Dr. Ji, you are too great!"

"With the vaccine, humanity will be saved, to hell with those zombies and viruses!" Xiao Siyan also waved his fist, and his little face was red.

"Hmm, you misunderstood, my vaccine is not for those monsters!" Dr. Ji was stunned for a moment, and quickly waved his hand.

Except for Xiaocao, several other children who were immersed in great happiness were all stunned, and Mei Mei couldn't help but ask, "Dr. Ji, what is your vaccine for?"

"My vaccine......" Dr. Ji was happy to explain to the lovely little girl.

"Dr. Ji, you're talking too much. A cold voice rang out.

Dr. Ji, who was interrupted, was a little unhappy, but he didn't continue, just scratched his head and said to Mei Mei, "When you grow up, grandpa will tell you about it." ”

"How many of you are messing around at the door?"

Xiaocao saw a middle-aged man in a suit and leather shoes walking from inside, looked at the new children one by one with a gloomy face, and finally snorted coldly.

"I don't know if I'm alive or dead. ”

Xiaocao saw that several children were full of unhappiness on their faces, and said first: "Thank you for letting us in, I am a college student majoring in chemistry, I have followed my mentor to do a lot of research related to vaccines, and I have also learned a lot about Dr. Ji's research, I hope to help a little." ”

"What can you do if you haven't graduated from college yet?" said the middle-aged man disdainfully.

"My assistant Mary was abandoned by you, more than half of the people in the research institute are infected with the virus, I need an assistant!" Dr. Ji began.

"You decide, if the vaccine doesn't succeed, you'll be given up too, doctor!" the middle-aged man said impatiently and turned to leave.

Seeing this nasty ghost leave, everyone breathed a sigh of relief.

"Thank you for giving us the opportunity to come down, Dr. Ji. Xiaocao said sincerely.
