It was still January 28 of the 23rd year.

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

These five nuclear submarines are the Pacific-class battleship - the No. 5 ship Nan Dayang; Super Luzon - Madagascar; Killer whale class No. 34, No. 35, No. 36.

Carlos Don Quixote, the captain of the Nandayang, is also the commander of this task force, the fleet's internal affairs officer is Li Xin, and the fleet's psychological counselor is Wu Yongxing.

Carlos looked at the charts, where they were in the Astronaut Sea in the Southern Ocean, less than 172 kilometers from Enderbidi, Antarctica.

They have been in a state of submersion since they were resupplied from a secret submarine base on the southern side of the island of Sumatra in Southeast Asia.

"Report, Penguin Station in Casey Bay, sending us an inquiry signal." The signal corps interrupted Carlos' thoughts.

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

"Yes."

On the magnetic field radar, you can see a variety of surrounding magnetic field signals, and after the integration of the supercomputing magnetic field radar imaging system, it becomes a three-dimensional image.

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

Since it is summer in the Southern Hemisphere, Australia and New Zealand, which are close to Antarctica, catch seafood in the Southern Ocean.

Of course, for the vast area of the southern ocean, dozens of fishing boats will be deserted.

Homo sapiens has two research stations in Antarctica, one at the Penguin Station in Casey Bay in Enderbig, and the other at the Blue Whale Station on Mill Island near Queen Mary's Land.

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

However, the task force did not emerge from the sea, but followed a small hidden trench into a huge undersea tunnel.

With a radius of 240 meters, this undersea tunnel is a huge undersea tunnel that was completed by Penguin Station employees using bacteriological corrosion technology to erode the ground for more than half a year.

In order to avoid the discovery of the hole, a special combination of genetically recombinant seaweed is also specially designed to form a rock-like layer at the hole.

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

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

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

The port has 20 berths, two of which are berths for ships of the 100,000-ton class.

After the Nan Da Yang floated, it carefully adjusted its hull on the water surface of the harbor so that it could sink quickly when it left.

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

The base rectangular exhibition is on the docks.

"Carlos, welcome to Antarctica."

After saluting, Carlos smiled and shook his head: "It's my pleasure." ”

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

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

A special survival pod is being carefully transported down by the soldiers, and the glass window of the survival pod is also hidden.

Fang Zhan turned his head and asked in a low voice, "This is the thing in the mission?" ”

"Yes." Carlos nodded.

"Then I'll go over and set up this survival pod first."

Wu Yongxing, a psychological counselor on the side, followed.

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

Several technicians checked the lines and various spare equipment.

Wu Yongxing asked, "What is the security level here?" ”

"Level A1, as long as you don't get hit head-on by a ground-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: "A few more sets of backup power supply and backup life support cabins need to be prepared, and another safe house is not enough, which is the key to whether the company can continue." ”

"One is not enough? But even if you build a few more, you won't be able to use only one when the time comes. ”

Wu Yongxing expressed his thoughts: "In this way, in the process of expanding the base, the safe houses should be arranged along the subway line, so that when one of the safe houses has a problem, the survival cabin can be quickly transferred to the other safe houses." ”

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

Wu Yongxing reminded: "Remember, the purpose of the existence of this base is to serve the survival cabin, and everything else must be compromised for this." ”

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

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 fanaticism, and he immediately folded his hands and bowed slightly.

One last check was done before the group rolled out of the safe house.

The Super Alloy door of the safe house slowly closes.

Fang Zhan, Wu Yongxing, and the team leader of the maintenance team had the permission to open the safe house.

The base of the base in the meeting room.

Fang Zhan gave a brief introduction to the situation of the base: "At present, our base has three 50 megawatt thorium-based molten salt nuclear reactors, two of which are in operation and one is in standby. ”

"The base has a population of 3,827 people, mainly young families, and the food at the base can support the daily needs of 20,000 people."

"In terms of weapons, equipped with 5000 sets of exoskeleton armor, as well as 3000 sets of working exoskeletons, light weapons and ammunition can be produced on their own."

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

Carlos looked at the base's profile: "Our task force will also be stationed in the Antarctic region in the future, so we need to add our 7,252 people, and the food production line should be increased." ”

Li Xin, who is in charge of housekeeping, calculated: "Considering the increase in population in the future, and just in case, the food production line at the base must reach the level of 100,000 people. ”

He continued: "In addition, all kinds of facilities must have security backups, as well as decentralized placement, so as 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, and no one can say what the future holds." ”

No one else has an opinion on this.

After all, the base in Antarctica was set up so that human civilization could be restarted after the destruction of the world.

Otherwise, Homo sapiens would not have gone to great lengths to build such a huge underground base in an inaccessible area like Antarctica.

The people who were selected were all young people who were already married, and they were all carefully selected to ensure that even if there was only one base left, these people could still reproduce a healthy group in the end.

The various facilities of the entire base have the characteristics of being quickly replicated.

At the same time, it is also necessary to ensure a high degree of self-sufficiency, and there is no need for external material imports.

This is thanks to a series of previous Homo sapiens practices in the Assam region, which have perfected various technologies for subsurface survival and for achieving material self-sufficiency in isolated environments.
