Deep Space Fleet

Time passed quickly, and now it is the fourth year that the new civilization has stayed on this planet... The entire fleet can't wait to start preparing for the next trip.

Four years, compared to the entire universe, is just a short moment, but for the human beings in Kunlun Mountains, it is a lot of time, and they can do a lot of things.

At the beginning of the fourth year, about 110,000 people left this star field on a large transport spaceship "Pelican" and returned to their base camp behind. This population figure is 10,000 fewer than expected.

And now, the day before the departure again, the entire fleet has undergone earth-shaking changes.

The parts damaged due to the war have been completely repaired, and people have added some new magnetic field generating equipment to the surface, that is, a voyage, which is enough to achieve higher speed and sail for a longer distance.

At the same time, the internal defense measures were completely reorganized, and the weapons in the outer military corridors were all updated. Not only some automated defensive weapons, but also some additional military fortresses. If there is another information paralysis, these internal fortresses can also defend for a long time.

In particular, the entire network system is divided into five levels of security.

The first-level network is a civilian network, the second-level laboratory network, the third-level military network, and the fourth-level emergency communication network, while the fifth level is the network system represented by Pangu Brain.

Each layer of network is isolated from each other and has very strict security measures.

On the other hand, as this time the rectification is about to reach its deadline, various material resources in the various warehouses inside Kunlun Mountain have been arranged to be full, and they have gradually become saturated...

Zhang Yuan himself is too busy!

Seeing crates of gold, platinum, and silver brought up by space elevators, all of which are real high-purity finished products, he felt a miraculous pleasure like a miser!

Humans... are indeed a visual animal, and they naturally like these shiny things.

Well, gold and silver are no longer the so-called general equivalents, but they are good industrial products.

Neohumans even have the luxury to use silver to make wires. Although there are superconducting materials now, ordinary wires still exist from the perspective of cost and reliability.

Not only Zhang Yuan, but also ordinary citizens. Everyone can see the robots working continuously under the space elevator and boxes full of goods, and they can always feel very happy.

In particular, this planet, as a young planet, has a lot of heavy element minerals that can be mined on the surface, far exceeding the normal terrestrial planets.

The phenomenon that causes this, is because...it's too young.

For example, the earth does not actually lack minerals such as gold, silver and platinum. How much gold does the earth have?

Six trillion tons!

But how much has humans mined from the earth?

Very little, about 120,000 tons, an insignificant one-fifth of a billionth.

This is because, with the passage of time, most of the heavy elements gradually sink to the depths of the earth's core under the action of gravity.

Even at a level close to the third-level interstellar civilization, it is impossible for human beings to dig out the gold deep in the earth's core.

Due to the scarcity of gold on the earth, people can only develop Mars and Mercury. Especially Mercury, that's why it will become a mineral planet and a heavy industry base in the later circum-solar system engineering system.

But this planet is different. Due to the short birth time, there are still many heavy metals that have not had time to sink to the core. In addition, frequent volcanic eruptions will erupt minerals again.

A lot of precious resources are dumped on the ground like garbage, it would be a crime not to take this opportunity to get more!

"Hey, Kunlun Mountain is not big enough, it has no tonnage. It's pretty good now." Zhang Yuan was sighing sadly. He felt like some kind of greedy creature in a fantasy novel—a giant dragon, wishing to take these Gold Mountain and Silver Mountain will be inspected again.

And the large warehouse that is currently being inspected is in a zero-gravity vacuum area, everyone is wearing power armor, and there are several assistants from the secretary department behind them, constantly telling various data.

"The demand for gold in our entire civilization is not very large. It is mainly used in aerospace glass and personal jewelry, so the current reserve is 50,000 tons."

"There is also the uranium-235 raw material, uranium hexafluoride, which has been purified and can be used in fission power stations, as well as in the manufacture of radioactive batteries... Oh, and there is also the manufacture of electromagnetic artillery shells, which are very effective in hitting the target. When there is a fission explosion, it will cause radioactive pollution, which is better than nothing..."

"The current reserve is 120,000 tons."

"The reserves of helium-3 are even larger, and it is the main nuclear fuel."

It is human nature to love wealth. These young people in the secretarial department blushed inexplicably as they talked, as if they were billionaires themselves.

"...Oh, and this piece is plutonium-239, an associated product of breeder reactors, which can be used to make batteries. The reserve is about two hundred tons."

Plutonium-239 is changed from uranium-238, that is, after uranium-238 is put into the reactor and irradiated, it absorbs one neutron to become uranium-239, and then releases 2 negatively charged electrons, increasing the number of protons from 92 to 94. , the element position is advanced by 2, and the property is changed to plutonium-239.

The reason why these radioactive minerals are still needed is not only for weapons, but also for the safety of the spacecraft. After all, nuclear fusion is a complex energy source, and it cannot be used as long as it is slightly disturbed. Nuclear fission is relatively simple, and the existence of two power systems can better guarantee the energy supply of the spacecraft.

"The materials in these warehouses are basically like this..."

After hearing these reports, Zhang Yuan was in a good mood. After inspecting these material reserves, the last thing was completed. The Kunlun Mountain Fleet will set off again tomorrow, leaving this planetary system without an owner.

He suddenly thought of something, and asked: "By the way, those biologists, have they found the most primitive life on this planet? They have already searched for many craters, haven't they found anything?"

"Your Excellency, Captain, I'm sorry, not yet." Dr. Li Cheng replied: "Our drones have dug some soil samples in different craters, and there are some complex organic substances in them."

"But after judging, it's not real life yet. If you want to really evolve life, 400 million years is too little, and it may take another 700 to 800 million years."
