Homo sapiens

northwest of Meroë.

The northern part of the Darfur Plateau is part of the Sahara Desert and has a typical Gobi Desert desert landscape.

The area of ​​this region is about 300,000 square kilometers.

In this desolate plateau desert.

A construction team of 500 people is secretly digging a huge tunnel deep into the plateau in the edge oasis on the east side of the plateau.

Shabuin, the leader of the construction team, looked at the tablet in his hand, which showed an excavation plan. The length of this tunnel is about 200 kilometers.

They have been digging for more than half a year, and now only the last few dozen kilometers are left.

Don’t think that the construction team of 500 people is small. In fact, due to the application of a large number of automated engineering equipment, new technologies, and engineering-assisted organisms, their construction scale is comparable to that of an engineering team of tens of thousands, and the efficiency is very high and the construction speed is very high. Very fast too.

Behind their construction team, there is another construction team. That construction team is responsible for building node underground cities. A node underground city needs to be built every 50 kilometers along the tunnel.

While Shabuin and his construction team were busy digging the tunnel, a train arrived at their temporary camp along the tunnel track.

To be precise, the temporary camp of the construction team is actually a train.

The width of this super tunnel is very large, and its diameter is usually about 30 meters, which is the same specification as the vacuum ring pipe in Motor Island Space City.

And for the sake of safety, the two tunnels are usually built simultaneously. The two tunnels are parallel to each other, and the distance is usually about 500 to 600 meters. Every 10 kilometers or so of the tunnel, a laterally connected auxiliary tunnel (about 10 meters in diameter) will be built. .

Once the construction team enters the tunnel for construction, they basically have to live in the tunnel for a long time.

Therefore, the Coral Construction Group specially customized a train-type "RV". Due to the ultra-wide gauge, this train has a relatively large carriage size and usually consists of 50 to 150 carriages.

For example, the Shabuyin construction team in front of us has a camp train with 86 carriages, which can accommodate 500 employees living here for a long time.

Of course, the company will also consider the physical and mental health of the construction workers. Usually this kind of work requires one month of work and one month of rest, and the couple works on the construction site together.

The train that just arrived was a supply train, and the shift changer also arrived.

Shabuin quickly drove his electric car to the camp.

In this kind of tunnel, all engineering equipment is powered by electric power, mainly to reduce oxygen consumption inside the tunnel.

Although the gas balance cabin of the camp train will always monitor the composition of gases such as oxygen and carbon dioxide in the tunnel, and release oxygen by absorbing carbon dioxide, thereby achieving the stability of the gas composition.

But if the internal combustion engine is used extensively, it will still cause unnecessary trouble.

Even if the construction team employees are equipped with bio-based armor and do not need to obtain oxygen from the air, the oxygen concentration inside the pipeline still needs to be maintained within a reasonable range.

When Shabuin came to the camp train.

Automated loaders are already replenishing the camp train, and the 100 employees who came to change shifts this week have already donned biomass armor and exoskeletons.

A middle-aged man with brown skin walked over and said, "Lao Sha, don't violate the company's regulations. Take a rest when you need to. I don't want to see you die from overwork."

The corner of Shabuyin's mouth twitched slightly: "I just came back from a vacation in the Red Sea last week. I am in great health. Manager, you are worrying too much."

The manager of Meroe Construction, a subsidiary of Coral Construction Group, is the man in front of him, Suchisi. He patted Shabuin on the shoulder: "Why are you still so thin? Have you gone to the hospital?"

"Haha, I'm not sick. The doctor said that there are several intestinal-related genes in my genes that inhibit the nutrient absorption rate, so I am thin." Shabuin explained helplessly.

The two chatted for a few minutes, and Su Qiesi also entered the topic: "In about half a month, the chairman will come to the Darfur Plateau for inspection. You must hurry up for the remaining 27 kilometers."

"The chairman is coming over?" Shabuyin's eyes widened.

"Well, after all, this project was formulated by the chairman himself."

Shabuin was a little curious: "Manager, by the way, what exactly is this project for? Is it necessary to do it on such a large scale?"

"Don't ask, this is a confidential project." Suchisi did not answer.

"Okay!" Shabuin immediately put away his curiosity: "The last 27 kilometers will take about 11 days. I will speed up the progress as soon as possible."

Su Chexi nodded slightly: "Thank you for your hard work. If you need anything, you can ask it at any time and the company will consider it as appropriate."

"Don't worry! I won't be polite to the company."

The two chatted for a while.

Seeing that the supplies were completed and the shift staff had handed over the work, Suchesi took the train back to Atron Oasis City.

The train was very fast, covering a distance of more than 170 kilometers in less than forty minutes.

Returning to Atron Oasis City, he asked his assistant to arrange the placement of the employees on shift, while he went to the design and planning center of the office building.

In the design and planning center, dozens of architectural designers, urban planners, and underground construction engineers are busy working on a large project.

Suchisi asked with great concern: "Engineer Anthony, how are the simulation tests of the dome design going?"

The middle-aged man with a messy beard spread his hands with bloodshot eyes: "Many situations have been simulated, including earthquakes, volcanic eruptions, asteroid impacts, and nuclear bomb blasts. They have all been tested. The situation can only be considered good or not bad."

Su Qiesi also felt helpless about this.

Human beings are still too small in the face of the power of nature.

Even technologically powerful Homo sapiens companies are helpless against many natural disasters.

He turned to another designer and asked: "Dr. Rosie, are there any problems with the design of the monitoring system?"

Rosie shook her head: "No, I have completed the first draft and am now conducting a simulation test. I guess there will be no big problem."

"That's good."

Suchisi looked at the holographic projection design model.

The entire design model is very grand.

In the middle is a flat pie-shaped hollow structure with a diameter of 100 kilometers and an internal height of 500 meters.

It is surrounded by six small bases with a diameter of 5 kilometers. Its main function is to arrange ancillary facilities and security facilities to ensure that no out-of-control situation occurs.

"Kraft, what's the status of your security system?"

Kraft, who looked calm, replied confidently: "I have added nuclear bombs to the self-destruction system, as well as gamma ray cannons. I will definitely not let anything about this project be leaked."

After some understanding, Suchesi re-updated the model of the design plan. He is also a doctor of architectural engineering. His level of various design plans and new technology applications is almost the same as that of everyone present.

He then asked others about the part they were responsible for. The only problem now was what to do with the excavated earth and stones.

After all, this is to hollow out a huge underground space with a diameter of 100 kilometers and a height of 500 meters.

So he had to find a way to make use of the rocks and soil.

This is both to reduce the input of external materials and to avoid attracting attention.
