Time passes quickly, and now 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 with the entire universe, it is only a short moment, but for humans in Kunlun Mountains, it is a long time and can do a lot of things.

In the early years of the fourth year, about 110,000 people left the star field on a large transport spacecraft "Pelican" and returned to the base camp behind them. This population figure was 10,000 less than expected.

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

The damaged parts due to war have been completely repaired, and people have also added some new magnetic field generation equipment to the surface, which is a voyage, which is enough to achieve higher speeds and sail longer distances.

At the same time, the internal defense measures have been completely rectified, and all weapons in the peripheral military corridor have been updated. Not only some automated defensive weapons, but also some additional military fortresses. If you encounter the next information paralysis, these internal fortresses can also be defended for a long time.

Especially the entire network system, it is divided into five levels of security.

The first-level network is a civil network, a second-level laboratory network, a third-level military network, and a fourth-level emergency communication network, while the fifth-level network 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 rectification is about to reach its deadline, various material resources are arranged in various warehouses within Kunlun Mountain and have gradually become saturated...

Zhang Yuan himself is really too busy!

Seeing boxes of gold, platinum, and silver being transported by space elevators, all of which were truly high-purity finished products, he felt a magical pleasure like a slave to the money!

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

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

New humans can even be as luxurious as using 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 robots working continuously under the space elevator and boxes of goods full of goods, and their moods can always be very good.

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

The reason for this is because... it is too young.

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

Six trillion tons!

But how many people mine from the earth?

Very few, about 120,000 tons, a tiny half of a million.

This is because, as time goes by, most heavy elements gradually sink to the depths of the earth's core under the influence of gravity.

Even if we reach the level of a third-level interstellar civilization, it is impossible for humans to dig out gold deep in the earth's core.

Because the earth's gold is scarce, people can only develop Mars, Mercury, and especially Mercury, so it becomes a mineral planet and a heavy industrial base in the subsequent ring solar system engineering system.

But this planet is different. Due to its short birth time, many heavy metals have not had time to sink to the core, and the frequent volcanic eruptions will erupt again.

A large number of precious resources are dumped on the ground like garbage. If you don’t take this opportunity to get more, it will be a sin!

"Hey, Kunlun Mountain is not big enough, it has no tonnage. It's already good now." Zhang Yuan sighed with a frown. He felt like a greedy creature dragon in the fantasy, and he wanted to patrol these gold and silver mountains again.

The large warehouse that is currently inspecting is in a gravity-free vacuum zone, everyone is wearing power armor, and behind them are several assistants from the secretary's department who keep saying various data.

"Our entire civilization does not have a great demand for gold, mainly used in aerospace glass and personal jewelry, so the current reserve is 50,000 tons."

"There are also these uranium-235 raw materials, uranium hexafluoride, which have been purified and can be used for fission power stations and radioactive batteries... Oh, and the manufacturing of electromagnetic shells. These electromagnetic guns will produce fission and explosion when hitting the target and cause radioactive pollution. It is better than nothing..."

"The current reserve is 120,000 tons."

"The reserves of helium-3 are larger and are the main nuclear fuel."

It is a natural nature of human beings to love wealth. As these young people in the secretary talk, their faces became rosy inexplicably, as if they were billionaires themselves.

"...Oh, and this one is plutonium-239, a companion product of the proliferation reactor, which can be used to make batteries. The reserve capacity is about 200 tons."

Plutonium-239 is transformed from uranium-238. That is, after uranium-238 is placed in the reactor and irradiated, it absorbs a neutron and turns it into uranium-239, and then releases 2 negatively charged electrons, increasing 92 protons to 94, and the element position moves 2 positions, and the properties change 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 cannot be used with a little interference. Nuclear fission is relatively simple, and the existence of two sets of power systems can better ensure the energy supply of the spacecraft.

"This is basically the case with the supplies in these warehouses..."

After listening to these reports, Zhang Yuan was in a very good mood. After inspecting these material reserves, the last thing was completed. The Kunlun Mountain Fleet will set off again tomorrow and leave this planetary system without a master.

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

"Sir Captain, I'm sorry, not yet." Dr. Li Cheng replied: "Our drone dug some soil specimens in different craters, with some complex organic matter in it."
