There are two in one, and then after everyone has rested, they start looking for a second wave of trading opportunities.

Yu Yifeng stretched his waist, just eight hours of sleep, it was extremely comfortable.

He stood up and walked a few steps, moved his body, and ate a little more high-energy food like toothpaste, and it tasted ...... Immediately made him feel refreshed.

"Let's sort out the technology that has been traded, and if there are still deficiencies, let's make a table and mark the key deficiencies. We can try to get these things from other civilizations. He commanded unhurriedly.

Everyone was full of energy and ready for the next preparations.

Although the new humans suffered a small loss in the trade with the multi-ball civilization, they invisibly gained more benefits...... That's the message!

The diplomat of the multi-ball civilization "half-pulled", which provided people with a lot of reference information.

For example, which civilization is easier to deal with, which civilization is better at a certain technology, and so on...... This information is very important to the new humans.

For example...... Some very well-known locations of mining planets, located near certain neutron stars, are filled with two rare elements, iridium and rhodium, and the wholesale price is cheaper than the Hicks market.

"Iridium is an essential element for aerospace and rhodium is an essential material for high-strength glass, but they are not common on ordinary terrestrial planets."

"Iridium, in particular, is widely used in industry, and if it is lacking, the performance of various space materials will definitely be somewhat compromised. To build an advanced spaceship, these metal elements are still necessary. ”

There is also some garbled information...... A certain civilization is weakened, is in a stage of internal chaos, and is in dire need of weapons and equipment, perhaps to take advantage of it; Or for example, a civilization with good luck has picked up very good garbage, and so on......

In short, there's everything.

Of course, this information is actually clearly priced, and the price is not high. The diplomat of the multi-ball civilization, because of gratitude, gave it directly to the new humans in the process of trading.

Anyway, Yu Yifeng didn't think that they had suffered a loss in the transaction and made up for the lack of interstellar common sense, he thought that he had made a profit.

In the next few hours, the new humans found another L3 "Baleba civilization" to exchange technology.

The individual of the "Bariba civilization" looks a bit like an octopus, with compound eyes like flies. According to human aesthetics, it looks very ugly......

Well, as a qualified civilized diplomat, Yu Yifeng didn't mind too much. Judging by "appearance" as a preference, it is definitely a fool's behavior.

Because this "Baliba civilization" is the most gossip-loving civilization in the entire trading market!

What the new humans value is that they love gossip......

The whole transaction process seems to be calm, and Kan Dashan after the transaction is more important.

“…… Total Showdown?! No, no, there is no such thing. What a decisive battle there is......"

"But the whole form of war is not very good for Homo erectus!"

The big octopus waved its tentacles and shook its head excitedly: "The Tiekui civilization is also an ancient civilization, it was not the main force of the Homo erectus system at the beginning, but they are getting stronger and stronger in the war, and they are really a war mad civilization......"

"At this rate of progress, they may be able to break through the weak barriers and become a great L5 civilization in one fell swoop."

"Unfortunately, their home planet was found and destroyed 8,000 years ago...... There is little hope. ”

"The war cost about 32 percent of the population, including a large number of cutting-edge scientists...... It's a pity, it's a pity. ”

This individual of the "Baliba Civilization" was in a very good mood after the transaction was completed, and kept talking about what he had seen.

It was as if having a different audience could bring him greater satisfaction......

"The King of Gossip really lives up to his name."

Yu Yifeng couldn't ask for it, interspersed a few sentences from time to time, saying that he was listening carefully, and every sentence could make the other party itch: "But it is said that they still have twenty-eight planetary-class spaceships, with a total population of about 30 billion, and they should still have the strength to fight." ”

There are different opinions, which makes Kan Dashan more fun, and the octopus said more energetically: "You think too simply! The war of interstellar civilizations, because of the faster-than-light curvature of navigation, it is very, very difficult to completely exterminate the other side......"

But because of the limitation of the speed of light, the territory of interstellar civilization will not expand too much. Generally speaking, it is best to run your home galaxy for a long time.

Nomads with too little population, like the New Humans, are not normal.

With hundreds of thousands of years of operation, the home galaxy defense system has become more and more perfect, carrying a large number of people, and it is also the scientific, political, and cultural center of the entire civilization.

"The destruction of the home planet is definitely a heavy blow to the Tiekui civilization!" Speaking of the key point, the octopus danced and spittle: "These twenty-eight planetary-class spaceships can't defeat the LLP silicon-based alliance, so they can only scatter and fight guerrilla warfare." ”

"But guerrilla warfare has advantages and disadvantages...... The reason is very simple, cosmic guerrilla warfare is not comparable to that of a planet, and the huge space distance makes it extremely difficult to communicate with each other. ”

"And only when a civilization is united can it exert its greatest strength. If all the planetary spacecraft are tens or hundreds of light years apart, hide themselves and go their own way. What do you think will happen after hundreds or thousands of years without communication? ”

The octopus turned its tentacles into a big ball, and then suddenly split, differentiated, and said, "It's like this...... An L4 civilization is in a state of division that has been unable to communicate for a long time. After thousands of years, if their ideology and system are not strong enough, they are likely to split directly, which is also the biggest disadvantage of fighting guerrilla warfare for a long time! ”

"The Tiekui civilization has a faint tendency like this...... Without the home planet, where is the political base? The hearts of the people are disheartened, as if they have lost their hometown. The Milky Way is so big, but it doesn't have its own foothold. ”

"Once the civilization is divided, because of the massive differentiation of population and technology, the talent is greatly reduced, and the civilization will further weaken, forming a vicious circle!"

Yu Yifeng was secretly surprised in his heart, this octopus is a bit level, what he said is very reasonable!

A group of experts at the back are also constantly discussing, and they think...... The big octopus is quite right.

If the new human race suddenly splits into more than two dozen batches and survives in different places for hundreds of years, will it still be able to merge perfectly? Is it okay to continue to recognize him as the leader of Yu Yifeng?

"It's difficult...... At the very least, there will be a certain amount of confusion. ”
