Homo sapiens.

It was still January 23, 1.

In the vast and inaccessible depths of the Southern Ocean, in the sea area called the Astronaut Sea, 5 submarines sailed silently in it.

The five nuclear submarines are the Pacific-class battleship-No. 5 Southern Ocean; the Super-Luzon-class-Madagascar;

The captain of the Southern Ocean, Carlos Don Quixote, also serves as the commander of this task force. The internal affairs officer of the fleet is Li Xin, and the psychological counselor of the fleet is Wu Yongxing.

Carlos looked at the chart. At this time, their position was in the astronaut sea in the Southern Ocean, less than 172 kilometers away from Enderby in Antarctica.

They have been submerged since they were resupplied from a secret submarine base on the south side of Sumatra in Southeast Asia.

"Report, the penguin station in Casey Bay sent us an inquiry signal." The signalman interrupted Carlos' thinking.

"Reply to them and say we'll be in Casey Bay in five hours."

"Yes."

On the magnetic field radar, you can see a variety of magnetic field signals around you. After the integration of the super-calculated magnetic field radar imaging system, it becomes a three-dimensional image.

Except for their five submarines, there are not many signals of man-made objects on the surrounding seabed, but there are many fishing boats fishing for krill on the sea surface.

Since it is summer in the southern hemisphere, Australia and New Zealand, which are close to Antarctica, will fish for seafood in the Southern Ocean.

Of course, for the vast Southern Ocean, if dozens of fishing boats are scattered, it will appear desolate.

Homo sapiens has two scientific research stations in Antarctica, one is the Penguin Station in Casey Bay in Enderby Land, and the other is the Blue Whale Station on Mill Island near Queen Mary Land.

After five and a half hours of snorkeling, they finally entered Casey Bay.

However, the task force did not come out of the sea, but entered a huge undersea tunnel along a small hidden trench.

The radius of this subsea tunnel is 240 meters. It is a huge subsea tunnel that was completed after more than half a year of excavation by the employees of Penguin Station using bacterial corrosion technology to erode the strata.

In order to avoid the discovery of the cave entrance, a special combination of genetically recombined seaweed is also used to form a rock-like mimic layer at the cave entrance.

At this time, the seaweed mimic layer has been opened, and the huge Southern Ocean slowly drives in.

The channel is on the continental shelf, with an average water depth of 350-400 meters, and a thick layer of glaciers above it, which basically blocks the entry of ordinary civilian ships.

Through a 6.3-kilometer undersea tunnel, the Southern Ocean finally arrived at its destination, which is a large diving port.

The port has 20 berths, two of which berth 10-ton ships.

After the Southern Ocean was floated, it carefully adjusted the hull on the water surface of the port so that it could sink quickly when it was convenient to leave.

More than an hour later, the other four submarines surfaced one after another, berthing at their respective berths.

The base is squarely spread out on the pier.

"Carlos, welcome to the Antarctic."

After saluting, Carlos shook his head with a smile: "It's my honor."

Li Xin, who was dispatched to serve as the director of the Department of Internal Affairs of the Antarctic District, and Wu Yongxing, the psychological counselor of the district, also greeted Fang Zhan.

Suddenly they all fell silent, looking solemnly at the cargo lock of the Southern Ocean.

A special life support cabin was being carefully transported down by the soldiers, and the glass window of the life support cabin was also covered.

Fang Zhan turned his head and asked in a low voice, "Is this the thing in the mission?"

"Yes." Carlos nodded.

"Then I'll go over and set up this life support cabin first."

The psychological counselor Wu Yongxing on the side followed.

Soon the life support cabin was escorted by Fang Zhan, Wu Yongxing and his party to a special room deep in the base.

Several technicians checked the wiring and various spare equipment.

Wu Yongxing asked: "What is the security level here?"

"A-level 1, as long as you don't get hit directly by the earth-penetrating hydrogen bomb, even if a full-scale nuclear war breaks out outside, you can sit back and relax here." Fang Zhan replied directly.

But Wu Yongxing shook his head: "We need to prepare a few more backup power supplies and backup life-support cabins. Another safe house is not enough. This is the key to the company's continuation."

"One is not enough? But even if you build a few more, you will not only be able to use one."

Wu Yongxing expressed his thoughts: "It can be like this. During the expansion of the base, the safe houses should be arranged along the subway line, so that when one of the safe houses has a problem, the life support cabin can be quickly transferred to other safe houses."

"Is that so?..." Fang Zhan thought for a while, and finally nodded: "Yes, I will arrange a design team in a few days to adjust the construction plan of each area."

Wu Yongxing reminded: "Remember, the meaning of the existence of this base is to serve the life-support cabin, and everything else must make concessions for this."

"Yes, I will definitely urge the design team to rectify."

Wu Yongxing turned his head and looked at the life support cabin that had been connected to the power supply of the safe house. His eyes were full of enthusiasm. He put his hands together and bowed slightly.

After making the last inspection, the group of people pushed out of the safe house.

The super alloy door of the safe house slowly closed.

Only Fang Zhan, Wu Yongxing, and the team leader of the maintenance team have the authority to open the safe house.

The base chief conference room of the base.

Fang Zhan briefly introduced the situation of the base to everyone: "At present, our base has three thorium-based molten salt nuclear reactors with a power of 50 megawatts, two of which are in operation and one is in standby."

"The base has a population of 3827 people, mainly families composed of young people. The food in the base can meet the daily needs of 2 people."

"In terms of weapons, it is equipped with 5000 sets of exoskeleton armor and 3000 sets of working exoskeletons. Light weapons and ammunition can be produced by ourselves."

"In terms of people's livelihood, hospitals and schools have been built here, as well as various entertainment facilities..."

Carlos looked at the brief introduction of the base: "Our task force will also be stationed in the Antarctic region in the future, so we need to add our 7252 people, and the food production line should be increased."

Li Xin, who is in charge of internal affairs, calculated: "Considering the future population increase and just in case, the base's food production line must reach the level of 10 people."

He went on to say: "In addition, various facilities must have safety backups and be distributed in order to avoid problems in one area and cause the entire base to shut down."

Carlos also added: "We still need to reserve a few more emergency escape routes. No one can say what will happen in the future."

No one else has an opinion on this either.

After all, the base in Antarctica was set up to restart human civilization after the world is destroyed.

Otherwise, Homo sapiens would not have spent so much effort to build such a huge underground base in an inaccessible area like Antarctica.

The people selected are all married young people, and they are all carefully selected to ensure that even if there is only this one base left, these people can still reproduce a healthy ethnic group.

The various facilities in the entire base have the characteristics of being able to be quickly replicated.

At the same time, it is also necessary to ensure a high degree of self-sustainability, without the need for external input of materials.

This is due to a series of practices of Homo sapiens in the Assam region, which has perfected various underground survival technologies and the technology to achieve material self-sufficiency in an isolated environment.
