Homo sapiens.

Northwest of Meroe.

The northern part of the Darfur Plateau, which is part of the Sahara Desert, is a typical Gobi desert landform.

The area of ​​the region is about 30 square kilometers.

In this uninhabited plateau desert.

A construction team of 500 people is secretly digging a huge tunnel to the depths of the plateau at the edge of the oasis on the east side of the plateau.

Shabu Yin, the leader of the construction team, looked at the tablet computer in his hand. On it was an excavation plan. The length of the tunnel was about 200 kilometers.

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

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

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

Just as Shabuyin and his construction team were busy digging the tunnel, a train arrived at their temporary camp along the track of the tunnel.

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

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

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

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

Therefore, Coral Construction Group specially customized a train-type "RV". Due to the use of ultra-wide gauges, this kind of train has relatively large compartments, usually consisting of 50 to 150 compartments.

For example, the Shabuin construction team in front of us, their camp train consists of 86 carriages, which can accommodate 500 employees to live 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 means one month of work and one month of rest, and the husband and wife work together on the construction site.

The train that just arrived was a supply train, and it was also the arrival of shift replacements.

Shabuyin hurriedly drove the electric car to the camp.

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

Although the gas balance cabin of the camp train will constantly monitor the composition of gases such as oxygen and carbon dioxide in the tunnel, and release oxygen by absorbing carbon dioxide, so as to achieve the stability of gas composition.

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

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

When Shabuin came to the camp train.

Autoloaders are already resupplying camp trains, and the 100 workers who came in for their shift this week have been donned in bio-based armor and exoskeletons.

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

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

The manager of Merroy Construction, a subsidiary of Coral Construction Group, is Su Qixi, the man in front of him. He patted Shabu Yin on the shoulder: "Why are you still so thin, old boy? Did you go to the hospital?"

"Hehe, I'm not sick. The doctor said that among my genes, several gut-related genes inhibit the rate of nutrient absorption, which is why I'm thin." Shabuyin explained helplessly.

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

"Chairman wants to come?" Shabu Yin widened his eyes.

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

Shabuyin was a little curious: "Manager, after all, what is this project for? Is it necessary to do it on such a large scale?"

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

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

Su Qixi nodded slightly: "Then thank you for your hard work. If you have any needs, you can ask them at any time, and the company will consider them as appropriate."

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

The two chatted for a while.

Su Qixi saw that the supply was completed, and the shift personnel had also handed over the work, so he took the train back to Atlon Oasis City.

The speed of the train is very fast, and the distance of more than 170 kilometers took less than 10 minutes.

Back in Atlon Oasis City, he asked his assistant to arrange the placement of shift employees, 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 with a big project.

Su Qixi asked with great concern: "Engineer Anthony, how is the simulation test of the dome design?"

A middle-aged man with a messy beard, bloodshot eyes and spread his hands: "Many situations have been simulated, including earthquakes, volcanic eruptions, asteroid impacts, and nuclear bomb explosions. They have all been tested, and the situation can only be considered good or bad."

Su Qixi also felt helpless about this.

Human beings are still too small in front of the mighty forces of nature.

Even a Homo sapiens company with powerful technology is helpless against many natural disasters.

He turned his head to another designer and asked, "Dr. Rosie, is there any problem with the design of the monitoring system?"

Rosie shook her head: "No, I've finished the first draft, and I'm doing a mock test now, so it's probably not a big problem."

"That's good."

Su Qixi looked at the design model of the holographic projection.

The whole design model is very grand.

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

It is surrounded by 6 small bases with a diameter of 5 kilometers. Its main function is to arrange auxiliary facilities and security facilities to ensure that there will be no out of control situation.

"Kraft, how's your security system going?"

With a calm face, Kraft replied confidently: "I have added a nuclear bomb to the self-destruct system, as well as a gamma ray cannon. I will never let anything in this project leak out."

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

He asked about the part that other people were in charge of. The only problem now was how to deal 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 use these rocks and soil.

This is not only to reduce the input of external materials, but also to avoid attracting attention.
