Chapter 359

Time goes by quickly, and now is the fourth year that new civilization has stayed on this planet The whole fleet can't wait to get ready for the next trip.

Four years, compared with the whole universe, is only a short moment, but for human beings in Kunlun Mountains, it is a lot of time and can do a lot of things.

At the beginning of the fourth year, about 110000 people took a large transport ship, pelican, to leave the region and return to their rear base camp. This population is 10000 less than expected.

And now, the day before we set out again, the whole fleet has changed dramatically.

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

At the same time, the internal defense measures have been completely rectified, and the weapons in the peripheral military corridors have all been upgraded. Not only some automatic defense weapons, but also some additional military fortresses. If we encounter the next information paralysis, we can also defend for a long time with these internal fortresses.

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

The first level network is civil network, the second level laboratory network, the third level military network, the fourth level emergency communication network, and the fifth level is the network system represented by pangunao.

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, all kinds of material resources in the internal warehouses of Kunlun Mountain are fully arranged, and gradually tend to be saturated

Zhang Yuan himself is too busy!

Seeing boxes of gold, platinum and silver being transported up by the space elevator, all of them are real high-purity finished products, he has a magical pleasure like a miser!

Human beings It's really a kind of visual animal. Naturally, I like these shiny things.

Well, gold and silver are not the so-called general equivalents for a long time, but they are good industrial products.

The new humans can even use silver to make wires. Although there are superconducting materials, ordinary wires still exist in terms of cost and reliability.

It's not only Zhang Yuan, but also ordinary citizens. Everyone can always be in a good mood when they can see the continuous flow of robots and boxes of goods under the space elevator.

In particular, this planet, as a young planet, can be mined heavy element minerals everywhere, far more than the normal earth like planet.

The reason is that It's too young.

For example, the earth is not short of gold, silver and platinum. How much gold does the earth have?

Six trillion tons!

But how much do humans extract from the earth?

Very little, about 120000 tons, a paltry one in 500 million.

This is because, with the passage of time, the vast majority of heavy elements in the role of gravity, are gradually sinking to the core depth.

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

Due to the scarcity of gold on earth, people can only develop Mars and mercury. Mercury, in particular, will become a mineral planet and a heavy industry base in the engineering system around the solar system.

But this planet is different. Due to the short time of its birth, there are still many heavy metals that have not been able to sink into the earth's core. Coupled with frequent volcanic eruptions, minerals will erupt again.

A large number of precious resources are just like garbage on the ground. If you don't take this opportunity to get more, it's a crime!

"Ah, Kunlun Mountain is not big enough. There is no tonnage. Now that's good. " Zhang Yuan is sighing with a sad face. He feels like a greedy creature in fantasy - the dragon. He wants to inspect these mountains again.

Now the large warehouse under inspection is in a gravity free vacuum area. All of them are wearing power armour. Behind them are several assistants of the Secretary Department, who keep talking about all kinds of data.

"The demand for gold in our whole civilization is not very large. It is mainly used in aerospace glass and personal jewelry, so the current reserve is 50000 tons."

"And these uranium-235 raw materials, uranium hexafluoride, have been purified and can be used in fission power stations and the manufacture of radioactive batteries Oh, there is also the manufacture of electromagnetic shells. When these electromagnetic guns hit the target, they will produce fission explosion and cause radioactive pollution. It's better than nothing... "

"The current reserve is 120000 tons."

"Helium-3 has a larger reserve and is the main nuclear fuel."

It's human nature to love wealth. These young people in the secretarial department, as they say it, blush inexplicably, as if they were billionaires themselves.“…… Oh, and this is plutonium-239, a byproduct of breeder reactors, which can be used to make batteries. The reserves are about 200 tons. "

Plutonium-239 is derived from uranium-238, that is, after putting uranium-238 into the reactor for irradiation, it absorbs one neutron and turns into uranium-239, and then releases two negatively charged electrons, increasing the number of protons from 92 to 94, advancing the element position by 2, and the property changes to plutonium-239.

The reason why these radioactive minerals are needed is not only for weapons, but also for the safety of spacecraft. After all, nuclear fusion is a kind of complex energy, which can not be used with a little interference. The nuclear fission is relatively much simpler. The existence of two sets of power systems can better guarantee the energy supply of the spacecraft.

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

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

He suddenly thought of something and asked, "by the way, have the biologists found the most primitive life on this planet? They've been looking for a lot of craters, haven't they found anything? "

"I'm sorry, sir, not yet." Dr. Li Cheng replied: "our drones dug some soil samples in different craters, and there are some complex organic matter in them."

"But after judgment, it's not real life. If you want to really evolve life, 400 million years is too little, maybe it will take another 70 million years. "
