The test room was at the rearmost position, and a group of people began to walk there mightily.

"So hot……"

"I can't do it anymore."

"It's really hot, is there any water?"

"Let's take a break, I can't walk anymore."

too hot……

"Everyone hurry up, it's almost there." The guard, with the dizzy short-haired girl, encouraged them: "Just ahead."

The front was coming to an end, and everyone supported each other to move forward.

The temperature is too high, they are still wearing isolation suits, and their skin is hot.

Finally found the test room, but the door of the test room cannot be opened.

"How to open this door?"

There is a rotating handle on the door, but no matter how they rotate, the door pattern does not move.

"Can't open..."

The guard wiped the rusty sign next to him, turned his head and asked, "Who has silver coins?"

They are all residents of the three districts, and silver coins are scarce. Who has more?

Chuzheng took out a silver coin and handed it over.

The guard gave Chuzheng a surprised look, but he didn't care about it at this time. He took the silver coins and threw them all nearby.

For each shot, a small red light lights up below.

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

Of course, like this kind of equipment, there will be special silver coins, and ordinary silver coins will definitely not have enough energy.

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

"I'm gone." There were so many task rewards from the bastard.

The guard looked at others again.

Chuzheng took the lead and took so many out, and someone squeezed out one.

Of the twenty people, only five of them took out silver coins in the end. One of them took five. After the guard cast the last silver coin, the red light finally turned to green.

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

The door that hadn't been activated for a long time was slowly opened, the lights inside were turned on, and the sounds of various machines were gradually sounding.

"Quickly go in."

"Don't squeeze."

"Help the person next to you."

The doorman came in last and closed the door,

-

Purify the outside of the system.

The guard was surrounded by people who went out, begging for an explanation.

After all, they were almost locked here.

These people have not been professionally trained. If they knew from the beginning that there were only five minutes in the end, could they remain calm?

This group of people made a lot of noise, and in the end someone directly used weapons to suppress them.

When these people stopped making trouble, they raised the number of silver coins to fifty.

Slap first and then give a sweet date, this group of people really calmed down.

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

The captain glanced at the closed door: "Go back."

He has little hope for the people inside.

Back in the refuge, everyone was asked not to talk nonsense, and they were never put inside again, staying in the space outside.

When the purification is complete and the air reaches the standard, the people in the refuge are released, and they each go to their own territory.

The guards all go to maintain order, and the rest of the guards who have been transferred will also return to the second and first districts.

The captain led people to the gate of the purification system again.

The captain's communication channel was always open, but no one contacted him.

The people inside, I'm afraid...

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

"Zizzi... Captain... open the door."

The captain's expression changed: "Are you all still alive?"

"All alive."

The captain immediately greeted people to open the door.

"Captain." Someone frowned: "These people come out, it's not easy to kill them."

In the previous wave of people, although they were angry, they were not kept in it. They could be tempted by profit.

But the people inside are different...

They almost died inside.

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

The captain frowned and said nothing.

The others were quiet, afraid to speak.

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

Maybe no one responded for a long time, and the people inside were obviously anxious.

"Captain, are you still listening?"

"Hello? Can you hear me?"

No one responded to that voice.

"Open the door." The captain said solemnly after some ideological struggle.

"team leader!"

"That's your comrade-in-arms!" The captain said: "Are you going to watch him die inside?"

Everyone looked at each other for a few seconds, and quickly went over to open the door.

The door of the purification system opened, and hot air gushed out of it.

-

Chuzheng came out last, unlike the others who collapsed on the ground. Her face was calm and cold, as if she had only stayed inside for a while.

"team leader."

The guard gave the captain a bear hug directly.

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

The captain patted his shoulder, and as soon as he looked up, he met the girl's gaze standing behind the crowd.

The girl's pupils are slightly light blue, and there is no wave inside, like a mirrored sky, as if they can see through people's hearts.

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

Chu Zheng didn't think they were discussing how to open the door.

It is more likely to want them to stay inside, and eventually run out of oxygen and die.

After all, these people are in trouble...

"Captain, thanks to this girl this time, otherwise we really won't be able to get out." The guard released the captain and pointed to Chuzheng.

The captain was a little confused by Chuzheng's sight. It stands to reason that such a little girl, he doesn't need to look at it...

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

Chu Zheng's face was expressionless, his eyes faintly cold: "You didn't let me die in it, I should thank you."

Although she was very skeptical... but she had no evidence, and they finally opened the door, and there was no anger from the manager.

I am too hard.

The captain over there froze, and after a while he deliberately misinterpreted Chu Zheng's meaning: "It is the duty of our guards to save you, so thank you."

Chuzheng refused one hundred silver coins. After all, she would not be short of this stuff in the future, but she did not say no, and asked them to distribute the silver coins to others.

She is not lacking, does not mean that others are not lacking.

And it can't be cheap these people are not.

Chu Zheng didn't ask for anything, so he left.

Others are still arguing about compensation, and they almost died in it. How can they be worthy of their trip if they don't pay more.

The captain looked at the direction Chuzheng was leaving, and it took a long time to withdraw his sight.

-

Chuzheng returned to his residence according to his memory.

It's just a small room, outside is a gallery bridge leading to the opposite side. Looking out from her room, the building is horizontal.

It is said that these buildings have special magnetic fields, which can ensure that people are inside, just like on the ground.

[Congratulations to my sister for getting a thank you card×1]

[Congratulations to my sister for getting a thank you card×1]

[Congratulations to my sister for getting...]

The King has a series of congratulations.

Chuzheng was a little surprised, are the people here so simple?

[...] No, just because you gave them the silver coins.

Chu Zheng: "..."
