Zhang Zi'en didn't say anything. The situation was critical now and time was running out. After the team was assembled, Zhang Zi'en waved his hand and said: "Let's go!"

A group of more than 300 people began to enter the conveyor channel.

There are three transportation methods in the working confluence area of ​​Xiongan No. 1 Shelter, namely rail cars, special capsule shuttles and working elevator shafts.

Rail cars are mainly used to pick up and drop off people in different working areas on the same floor, while special capsule shuttles are mainly used to transport people to some special working areas. The working elevator shaft is responsible for transporting people up and down, and personnel on duty are usually arranged to uniformly manage the start and stop.

The floor where Natsume is located is -98, which is located 370 meters underground. It already belongs to the bottom area of ​​the shelter. However, there is still a 100-meter drop from here to the area where the water circulation system is located. Even if the elevator shaft is directly accessible,

It takes about two minutes.

Although more than 300 people could be transported to the destination at once, Natsume always felt a little uneasy.

Li Dan stood next to Natsume. She felt everyone's nervousness and quietly held Natsume's hand. Natsume was a little surprised, but did not shake it away. Instead, he squeezed Li Dan's hand and gave her some encouragement.

Halfway down, Zhang Zien's face became extremely ugly. He took out his communicator and said: "Attention, all groups, the sedimentation tank has begun to overflow. The first thing we do when we arrive is to join the leading team, and then proceed as we planned before.

Block it! Remember, don’t build the temporary dam too high, as this will not be convenient for our maintenance personnel to enter and exit.”

"Roger!" came the responses from the other end of the communicator.

Li Dan looked at Xia Mu in surprise, and Xia Mu looked at Zhang Zi'en and said, "Brother Eng, I will take a team of people in to check the situation later. You can direct them outside to seal the overflow."

Zhang Zi'en said, "Hey, it's better for me to do this kind of dirty work. You're so clean, so it's not appropriate for you."

Li Dan didn't understand what this dirty work meant.

As a result, before Natsume could say anything, the elevator reached its destination.

Before the door even opened, the stench poured into the elevator. Li Dan frowned and almost vomited.

Natsume glanced at her and said, "Why don't you go back? If you get busy later, I won't be able to take care of you."

Li Dan waved his hand and said: "It's okay, I'm not a child, I can take care of myself, but you...you don't really plan to bring people into the pressure pump, do you? Can you repair that thing?"

Natsume smiled and said: "I couldn't do it before, but I have learned a lot during this period, which should be put to use."

However, Zhang Zien said inappropriately: "You can show off to other girls after you learn a little bit about it. Okay, you can just watch from outside while I take people down to repair it."

Natsume scratched his head in embarrassment, while Li Dan covered his mouth and snickered.

The door opened, and people were coming and going outside. A loud voice kept shouting at the disorganized staff: "What are you running around for? It's just overflowing! Use a blocker to block it! Don't panic!"

Zhang Zi'en frowned when he saw this and said: "The team led by Lao Zheng... Hey... Okay, all groups, pay attention, it's time to work! Remember, don't panic! Don't build the dam too high, it will hinder the development of the dam."

Maintenance personnel come in and out! Do you know!"

"knew!"

With that said, more than 300 people entered the accident area.

The air is filled with a disgusting stench, which is the smell emitted by the overflow caused by the backflow of sewage throughout the shelter after the water circulation system went out of control.

Li Dan tried to keep herself calm, and she said to Natsume: "Natsume, do you know where the control room of the water circulation system is?"

"Know."

"Take me there! I want to see the structure diagram of this system."

Natsume didn't hesitate. He watched Zhang Zien start arranging people to get the blocker, and he took Li Dan to the control room without intending to enter the forward circulation system.

The water circulation system is located on the right side of the bottom floor of Shelter No. 1 in Xiongan New District. It is at the same depth as the controllable nuclear fusion generator unit that provides power for the entire shelter, but both are independently divided areas.

They are different from each other, so Natsume does not have to worry about overflowing water causing damage to the power supply system.

But above the fan-expanded water circulation system is the ecological circulation system of the refuge, which mainly provides the refuge with sufficient oxygen and aquatic microorganisms required for marine algae reproduction.

If the water circulation system area overflows seriously or is even completely damaged, the backflow sewage will inevitably seep into the ecological circulation system and cause irreversible damage to the system. Therefore, there is not much time left for summer vacation.

He looked at the time, estimated the buffering time, and set an alarm for seven hours.

Li Dan was brought outside the control room. The guards at the entrance did not stop him when they saw Natsume. However, when they saw that he was bringing a woman with him, the guards were a little embarrassed.

Fortunately, Li Dan had all her work ID with her, and after she showed her identity, the guards got out of the way.

In the control room, a group of staff were trying to prevent the accident from worsening through the mechanical intelligent maintenance system of the water circulation system, but the situation had little effect.

When Li Dan came in, he saw a beautiful girl slap a man who was a head taller than her in the face.

"Get out!" The girl only said one word, and the man tremblingly picked up his hat and ran away.

Li Dan was startled and was about to ask Natsume who this was.

Then I heard Natsume say: "Masato? Why are you here too?"

The cold-faced Masato Shimizu changed her mind. She didn't need to come here originally, but the Shimizu family was responsible for funding the construction of this shelter. Most of the engineers and design team were also hired by the Shimizu family. It has only been in operation for a year and a half.

Faced with this kind of problem, as the second young lady of the Shimizu family, Masato Shimizu stepped forward to settle the matter.

When she saw Natsume, Masato's face improved slightly, but when she saw Li Dan holding hands behind Natsume, her face, which had just improved, turned gloomy again.

"This is something belonging to our Qingshui family. Of course I have the obligation to repair it." Masato Qingshui said, turning his head and scolding the staff: "You are a bunch of trash! Why didn't the Qingshui family see you clearly when they signed the contract with you?

This bunch of trash is useless? How can they not solve such a simple problem?"

Natsume, who had rarely seen Masato Shimizu get so angry, was so shocked that he could not speak.
Chapter completed!
