At the back of the test room, a group of people began to march towards it.

"It's hot..."

"I'm going to die."

"It's really hot. Is there any water?"

"Take a rest. I can't walk."

It's too hot

"Hurry up, everyone. It's almost there." The guard, with a dizzy girl with short hair, cheered them up: "it's right ahead."

The front is coming to the end. We help each other to walk forward.

The temperature is too high, they are still wearing isolation clothing, skin is burning.

It was hard to find the test room, but the door could not be opened.

"How do you open the door?"

There's a revolving handle on the door, but no matter how they rotate, the door doesn't move.

"I can't open it..."

The guard wiped the rusty sign next to him and turned to ask, "who has silver coins?"

They are all residents of the three districts. Silver coins are scarce. Who will have more?

Chu Zheng took out a silver coin and handed it over.

The guard looks at Chu Zheng in surprise, but he doesn't care about it at this time. He takes the silver coins and throws them into the side.

Every time you cast one, a small red light will light up below.

There is energy in the silver coin, which is used to start various devices.

Of course, there will be special silver coins for such equipment. The energy of ordinary silver coins is certainly not enough.

"Not enough." The guard looks at Chu Zheng.

"I'm gone." That's all the mission rewards given to you, son of a bitch.

The guard looked at the others.

Chu Zheng takes the lead to take so many out, someone buckle rope of touch out one.

Twenty people, only five of them took out silver coins. One of them took five. After the guard cast the last silver coin, the red light finally turned green.

With a click in his ear, the guard looked happy and immediately turned the handle.

The door that has not been started for a long time is slowly opened, the lights inside turn on in turn, and the sound of various machines running gradually rings out.

"Get in."

"Don't squeeze."

"Support the people next to you."

The guard is the last one to come in and close the door,

-

outside the purification system.

The guards were surrounded by the people who went out, asking for explanations.

After all, they were almost locked up here.

These people have no professional training, if they know from the beginning that there are only five minutes, can they keep calm?

This group of people made a lot of trouble, and finally someone directly used weapons to suppress them.

When these people stopped making trouble, they raised the silver coins to 50.

First slap, then give a sweet date, this group of people really quiet down.

The purification system works, the fog outside is decreasing, and the familiar buildings can be seen gradually.

The captain looked at the closed door: "go back."

He had little hope for the people inside.

Back in the shelter, everyone was asked not to talk, and they were not put in any more, in the space outside.

When the purification is completed and the air is up to standard, the people in the shelter are released and go to their own territory.

All the guards went to keep order, and the rest of the guards who were transferred back to the second and the first districts.

The captain and his men arrived at the gate of the purification system again.

The captain's communication channel was on all the time, but no one contacted him.

I'm afraid the people inside

At this moment, there was a sound of electric current on the communication channel.

"Zizizi Captain Open the door. "

The captain's face changed: "are you all alive?"

"All alive."

The captain immediately called for the door.

"Captain." Some people frown: "these people come out, can't send."

Before that group of people, although they were angry, they were not locked up in the end and could be lured by interests.

But the people inside are different

They almost died in it.

In underground cities, the lives of ordinary people are not so valuable.

The captain frowned and said nothing.

The rest of them were quiet and did not dare to speak.

The voice from the communication channel continued: "Captain, we don't have enough oxygen. Open the door quickly..."

Maybe no one responded for half a day. The people inside were obviously worried.

"Captain, are you still listening?"

"Hello? Can you hear me

No one responded to the voice.

"Open the door." After some ideological struggle, the captain said in a deep voice.

"Captain!"

"Those are your comrades in arms!" The captain said, "you want to see him die in it?"

Everyone looked at each other for a few seconds and quickly went to open the door.The door to the purification system opens, and hot air comes out of it.

-

Chu Zheng was the last one to come out, which was different from that when others came out and collapsed on the ground. Her face was calm and cold, as if she had been inside for a while.

"Captain."

The guard gave the captain a bear hug.

"I almost thought I couldn't see you!"

The captain patted him on the shoulder and looked up at the girl standing behind the crowd.

The girl's pupils are slightly light blue. There are no waves and no waves inside. It looks like a mirror sky. It seems to be able to see through people's hearts.

The guard contacted them to open the door. Why was the long silence in the communication video?

Chu Zheng doesn't think they are discussing how to open the door.

It's more likely that they want to stay in it and die of oxygen depletion.

After all, these people come out, but it's trouble

"Captain, this time thanks to this girl, otherwise we really can't get out." The guard releases the captain and points to Chu Zheng.

It's unnecessary for him to put too much pressure on the head of Zheng

The captain took a deep breath and took the initiative to walk over: "this time, thank you very much for your help. We will prepare 100 silver coins for you."

The beginning Zheng face is expressionless, the eye light faintly pan chill: "you didn't let me die inside, I should thank you."

Although she doubts But she had no evidence, and people finally opened the door, and there was no serious reason to be angry.

I'm too hard.

The captain over there was a stiff expression. After a moment, he deliberately misinterpreted Chu Zheng's meaning: "it's our duty to save you. You're welcome."

Chu Zheng refused 100 silver coins. After all, she would not be short of them in the future, but she did not say no and asked them to give them to others.

She does not lack, does not mean others do not lack.

And it can't be cheap. These people aren't.

Chu Zheng didn't ask for anything. She just left.

Other people are still making compensation problems. They almost died in it. If they don't make more money, how can they afford this trip.

The captain looked at Chu Zheng's direction of departure and took a long time to recover his sight.

-

, go back to your home.

Is a very small room, outside is a corridor bridge leading to the opposite side, from her room to the outside, the buildings are all horizontal.

It is said that there are special magnetic fields in these buildings, which can ensure that people are inside, just as they are on the ground.
