After the notification sounded, their locked door clicked and opened automatically.

Han Qingxia jumped down from the upper floor.

She was the first to leave the room.

At this time, many people had appeared in the corridor outside.

People from the first four rooms came out one after another.

Han Qingxia stood in front of the door and looked at them. She noticed that there were basically one or two people missing in every room.

The man in the white coat came up to everyone, counted the number of people, and led everyone forward.

No one at the scene dared to speak.

Everyone remained extremely quiet. Han Qingxia was in the team, observing the surrounding environment.

Doors are everywhere you look.

There are doors on both sides of the long corridor, and there is still a door at the end of the corridor.

Still the biggest one.

"Ding——" The leader swiped the access card and the door in front of him opened.

A gust of cold air blew out from behind the door.

"All of you wait according to your numbers and wait for your number to be called!" the team leader said coldly.

"No. 7871 goes in first!"

Hearing his number being called, the first man raised his hand and walked behind the door.

Han Qingxia looked at the situation, her mind raced, and she raised her hand and said, "Boss! My stomach hurts!"

The man in the white coat frowned and looked at her.

"My stomach hurts. I really can't take it anymore. I need to poop quickly! If I can't take it anymore, I'll do it right here. You all carry me over there and hold your breath. I'm sure it won't delay anyone."

The man in the white coat suddenly looked very unhappy. "Go in with her, quickly!"

With a beep, he swiped open a door, and another white coat of a lower rank led Han Qingxia inside.

Seeing this, Han Qingxia said something to Wen Yiyi and quickly followed.

After entering this door, there is a single room with the word "toilet" in front of you. Outside the room there is a washbasin and another door that leads to an unknown place.

Han Qingxia looked at the terrain carefully. Are all these places connected by various doors?

"Hurry up!"

There was an urging voice behind her.

Han Qingxia heard the voice and turned around and said, "Boss, I'm having my period. Do you have any sanitary napkins?"

The man in the white coat listened to her words, his face hidden without any emotion, "No, hurry up."

Han Qingxia couldn't get any more information from him, so she pushed open the bathroom door and went inside. The bathroom was the only place without surveillance, but the ceiling above was solid and she couldn't leave at all.

Han Qingxia looked at the toilet in front of her and an outlet next to it, and she suddenly came up with an idea.

“Oh no!”

The moment the man in a white coat waiting outside heard the sound, he immediately rushed over.

But when he just entered the bathroom area, he stepped on a lot of stagnant water.

water.

A burst of electric current passed through the accumulated water, and the man who had just rushed to the bathroom door was knocked to the ground by electricity.

Han Qingxia looked at the man who fell to the ground, and then she stopped the water flow that was directed toward the socket with her palm. The water that had just flooded over his ankles quickly receded. Han Qingxia fell from the toilet, stepped into the water without current, and picked up the house number plate on the man's body.

She noticed that the man's house number was C897.

She used her psychic powers to look around the bathroom door, then rushed to another door pretending to be panicked and looking for help.

The door opened with a click.

After the door opened, a brand new corridor appeared in front of Han Qingxia.

On both sides of the corridor are observation rooms similar to wards.

In each observation room lived a person with his hands and feet tied.

They were tied to the beds, with countless tubes inserted into their bodies, some of which were injecting fluids into them, and some of which were extracting fluids. Everyone was in great pain.

Han Qingxia saw an acquaintance.

Song Dapeng.

Song Dapeng, who was just taken away today, no longer looked like a zombie. His gray eyes stared blankly outside, and the black blood vessels on his face were reflected in the pale skin.

His body was connected to a dialysis machine, and a large amount of black liquid was drawn out. After passing through the machine, it flowed back into his body as a white liquid.

He no longer looks like a zombie, but like a real dead person.

At this time, Han Qingxia heard the sound of conversation.

"Did you fail all the tests yesterday?"

"Yes, all ten experiments failed."

"It's really hard to find a compatible mother. We have reduced the toxicity to the lowest level, but none of them can handle it."

"Don't talk about it. They are screening the strongest mothers through physical examinations outside. We should hurry up and find a way to reduce the toxicity. The S-level has issued a death order. We must find someone who can resist the original virus and produce antibodies."

The voice gradually got closer, and Han Qingxia felt that the person who was speaking was about to come out of a room in front. She scanned the surroundings and used the card in her hand to open Song Dapeng's room.

When her card touched Song Dapeng's room, the alarm sounded immediately.

Before Han Qingxia could react, the light above her head flashed red, and several red lasers fell around her. The two people in white coats who had just spoken in front rushed out.

"Who are you!"

Everyone else in the corridor came out as well.

"I don't know where this is either." Han Qingxia raised her work badge, "I'm here to ask for help!"

A man in a white coat walked out from the crowd. He stared at Han Qingxia coldly, "Where are you from?"

"Someone just brought me to the toilet. The water tank in the toilet suddenly broke down, leaking water and causing electric shock. The person fainted, so I came out to find someone to help. I don't know why I ended up here."

Han Qingxia said this sincerely.

The leader in a white coat glanced at Han Qingxia, and immediately led his men back in the direction she had just walked, "Take her with you."

The group of people behind him rushed forward, and Han Qingxia cooperated very well. They didn't even need to catch him, and he followed obediently behind them.

After the group of people followed him to the bathroom, they found the man in the white coat lying in a pool of water due to electric shock.

The leading man immediately used a headset to contact the people in the monitoring room to conduct surveillance.

Half a minute later, he looked at Han Qingxia with suspicion, and called others with the headset, "B179, come here."

Another door of the bathroom opened, and the person who originally brought Han Qingxia in came in.

"B179, something's happened to your people, be careful." He said to the man.

"Yes! A-level!"

Through the conversation between these people, Han Qingxia finally understood what those ABCs meant.

It turns out that there are also hierarchical differences among them.

The white coat she just got was the lowest level, C grade, the person leading the team was a B grade, and the highest level one was an A grade.

So just now because she was using a Class C card, she couldn't open the door and the alarm was triggered.
