Chapter 343: Don’t Stand Under a Dangerous Wall

Last time, it was nuclear energy.

Let’s not talk about the distant past. The space elevator technology itself is also very valuable to humans. As mentioned before, human civilization is now a wandering civilization. When encountering danger, the main thing is to quickly replenish supplies and quickly escape.

With a space elevator, you can just go fishing like fishing.

Of course, the space elevator has more than just advantages. Although humans have not yet built it, after getting a full set of space technology, humans noticed it because the data provided by the Nairs was very comprehensive.

The weight of cargo that a space elevator can carry depends on the quality of its cable material. The stronger the cable, the stronger the carrying capacity of the space elevator.

And it has been clearly stated in the data of the Nairs that many large finished components, such as a spacecraft that cannot fly into space by itself, cannot be carried by the space elevator at present, so their Pot Cover No. 5 planet uses two modes of transportation at the same time.

However, if it is only used to transport mineral resources and supplies between heaven and earth, then the space elevator is more than right. In addition, the passenger capacity of the space elevator is incomparable to the orbital mass accelerator.

It can be said that with the space elevator technology, the human beings' space transportation capacity has increased by at least ten times.

Now the manufacturing department of human beings has begun planning. After leaving the Pot Cover Mangmang Star and reaching the next star, they will first build five.

The reason why they don't build it here is because there are not enough materials. After all, this is the territory of the Nair people. It's good enough for humans to replenish the materials and fuel of the fleet. They don't expect the Nair people to give them resources for a few more space elevators.

Moreover, as long as you reach an ownerless star system, you can have as many resources as you want. It is completely inexhaustible. And there are so many ownerless stars in the universe. After the Pot Cover Mangmang Star, you just need to avoid the sphere of influence marked on the Nair star map.

This is also the star system that humans will go to next. Since the Nair people have given the star map to humans a long time ago, the target has been selected, which is about 27 light years away from the Pot Cover Mangmang Star.

After everything here is completed, humans will leave.

According to the current supply progress, it is estimated that the fleet will be supplied in about five years. In fact, if humans were allowed to mine resources themselves, it would take less than five years, but the Nair people did not allow it, so humans could only wait to receive supplies from the Nair people one ship after another.

Fortunately, the Nair people also have their own fleet, so they are quite experienced in supplying supplies, otherwise this time might be longer.

On this day, Yue Yuan was handling daily affairs in the office. Before he went out, he heard a knock on the door.

After Yue Yuan shouted "Come in", he looked up at the door and saw a man and a woman walking in.

Yue Yuan knew all the leaders on the Tianqin. The man was from the staff department, his surname was Wei, and the woman's surname was Lei, who was the general person in charge of the supply this time.

"Marshal Yue, are we really not waiting for the transport fleet coming from the direction of Da Lie Star?" The speaker was Chief of Staff Wei.

Yue Yuan shook his head and said, "No more waiting! Five years later, that fleet will probably reach the deceleration distance in three years. If we wait any longer, if that fleet is not a transport fleet, we may get into big trouble. We are not afraid of trouble, but there is no need to take unnecessary risks."

From what Yue Yuan said, we know that the plan of the Nair people on the Pot Cover Mangmang Star was still useful. At least many people in the command headquarters, including Yue Yuan, felt that this matter was too strange, so it was better to leave early.

As the saying goes, a gentleman does not stand under a dangerous wall. Although the fleet may really be a transport fleet as the Nair people said, and it also carried a lot of goods from the Great Star, but now humans have already got what they want on the Pot Cover Mangmang Star, there is really no need to take this risk.

"I understand. Commander Yue, there is one more thing. I apply to stay here for the next five years to assist Director Lei, so I won't go back with the Tianqin."

"Oh?" Yue Yuan raised his eyebrows, glanced at the staff officer Wei and then glanced at Director Lei next to him, as if he realized something, so he nodded and said: "Okay, I'll give you a five-year vacation, but after five years, you have to report back to the Tianqin."

"Thank you, Commander Yue." Staff Officer Wei saluted Yue Yuan happily.

"Well, Director Lei is here for this too?" Yue Yuan looked at another one.

"No, Chief, I'm here to report on the recent storage of materials." Director Lei of the Supply and Logistics Department replied.

"Okay, I know, just send the data back according to the procedure, no need to report in person." Hearing this, Yue Yuan knew it was an excuse. Director Lei must have come here to help Staff Officer Wei ask for leave, and probably didn't expect Yue Yuan to give him leave so readily.

"If you have nothing to do, just go about your own business." Yue Yuan issued an order to send the guests away.

"Yes, General Yue!"

"Understood, Chief."

The two turned to leave, but just as they stepped out of the office door, they heard Yue Yuan's words floating into their ears: "By the way, you two have to have more children in five years. If you are busy, you can file a case with the Population Management Department. They will handle it. Well, the main reason is that the weightless environment has some impact on the growth of the baby."

Yue Yuan's words made the two pause, but they didn't mean to stop.

Just now, after Yue Yuan saw the clue, he personally checked the validity period of the two's life potions and found that they were all expiring in these two years. He knew that the two were going to start a family, so he gave them a five-year vacation so readily.

Due to the problem of life potion, the population of human beings is growing very slowly now. If it is a normal life, the birth rate is okay, but if it is during interstellar voyage, forget it.

Fortunately, there are few natural deaths, otherwise it will be negative growth.

Speaking of which, from the emergence of Callisto to the present, new life potions have been continuously developed, and no human has died of old age so far. From this perspective, it cannot be said that it is the fault of life potions.

The main problem is the expiration time of the potion for both men and women.

For the two lovers, if one of them has expired, but the other has lasted for decades or even hundreds of years, they will probably not have a chance until they die of old age.

In fact, for hundreds of years, the population management department has also noticed this situation, but if the population system does not change, the population growth rate will definitely not have a big breakthrough.

Because the original regulation was that men and women must have children before they can register to use life potions, so the main force of human population growth now is actually newborns who have grown up generation after generation.

As for those who have used life potions, even if both men and women have reached the expiration date hundreds of years later, these people do not have such a strong desire to have children, and a large part of them directly apply for renewal of the potion.

This is one of the reasons why, after so many years, the human population is still less than 200 million.
