Chapter 366

Time passed quickly. Now it is the fourth year for the new civilization to stay on this planet... The whole fleet can't wait to start preparing for the next trip.

Four years, compared with the whole universe, is only a short moment, but for humans in the 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 spacecraft "Pelican", left the star domain and returned to their rear base camp. This population figure is ten thousand less than expected.

Now, the day before setting out again, the whole fleet has undergone earth shaking changes.

The damaged parts caused by 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 longer distance.

At the same time, the internal defense measures have been completely rectified, and the weapons in the peripheral military corridors have been upgraded. Not only some automated defense 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.

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

The first level network is the 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 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 the deadline, various material resources are arranged to be full in various warehouses in Kunlun Mountain, which has gradually tended to be saturated

Zhang Yuan himself is too busy!

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

Human beings... Are indeed a kind of visual animals. Nature likes these shiny things.

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

New humans can even be extravagant enough to make wires with silver. Although there are superconducting materials, ordinary wires still exist in terms of cost and reliability.

Not only Zhang Yuan, but also ordinary citizens. Everyone can always be in a good mood when they can see the robots working under the space elevator and boxes of goods.

In particular, as a young planet, the earth's surface can be mined for heavy element minerals everywhere, far exceeding the normal earth like planet.

The reason for this phenomenon is... It's too young.

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

Six trillion tons!

But how much has man mined from the earth?

Very few, about 120000 tons, an insignificant one of 500 million.

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

Even at the level close to the third level of interstellar civilization, it is impossible for mankind to dig 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 industrial base in the engineering system of the ring solar system behind it.

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

A lot of precious resources are dumped on the ground like garbage. If you don't take this opportunity to get more, it's a sin!

"Alas, Kunlun Mountain is not big enough. There is no tonnage. Now it's good. " Zhang Yuan is sighing with a sad face. He feels like a greedy creature in a fantasy novel - giant dragon. He wants to patrol these Jinshan and Yinshan again.

The large warehouse being inspected now is in a gravity free vacuum area. Everyone is wearing power armor, and behind him are several assistants of the Secretariat who keep telling 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 plants and the manufacture of radioactive batteries... Oh, there is the manufacture of electromagnetic shells. These electromagnetic guns will produce fission explosion and cause radioactive pollution when they hit the target, which is better than nothing..."

"The current reserve is 120000 tons."

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

It is human nature to love wealth. These young people in the Secretariat, as they say, have an inexplicable ruddy complexion, as if they were billionaires.

"... Oh, and this is plutonium-239, an associated product of breeder reactors, which can be used to make batteries. The reserve is about 200 tons. "

Plutonium-239 is changed from uranium-238, that is, after uranium-238 is irradiated in the reactor, it absorbs a neutron and becomes uranium-239, and then releases two negatively charged electrons, increasing the number of 92 protons to 94. The element position advances by two bits, 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 complex energy, which can not be used with a little interference. Nuclear fission is relatively much simpler. The existence of two sets of power systems can better ensure 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 these material reserves, the last thing was completed. The Kunlun Mountain fleet will set off again tomorrow to 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 looked for many craters, haven't they found anything? "

"Sir, I'm sorry, not yet." Dr. Li Cheng replied: "our UAV dug some soil samples in different craters, in which there are some complex organic substances."

"But after judgment, it is not real life. If you want to really evolve life, 400 million years is too little. It may take another seven or eight billion years. "
