The counterparty of this time, the "Amoeba Business Alliance", is a very, very old business alliance that has existed in the era of "Black".

Therefore, these basic information are still known to the new humans.

The older the civilization, especially the one that has been spanning the galaxy for more than 10,000 years, the stronger it will be, which is an inevitable event.

Not because of the accumulation of scientific experience, nor because of the huge material and population, but because of the ...... Intellectual barriers.

Second screening in the universe!

If it can't pass the second screening in one go, the interstellar civilization will inevitably decline after hitting the bottleneck, and it will not be possible to survive for a long time under the infinite flow of time.

This is the "law of entropy increase" in the universe, a law of nature that is difficult to violate!

So, the founder of the "Amoeba Business Alliance...... The amoeba civilization is likely to be an interstellar civilization above L4 that has broken through the second screening.

Such a civilization is truly powerful, and Yu Yifeng and others know it.

The new human civilization is just a "cheating" way, thinking that it has improved its IQ and passed this "bottleneck". But the current side effects are already emerging, that is, the birth rate is low, and no one can afford to die.

As for the other side effects, there may be none, there may be...... I don't know yet.

"So we speculate that the long-standing amoeba civilization is at least an L5 or higher civilization. If it is a decaying civilization, it is impossible to support the interstellar market for a long time. When the benefits far outweigh the risks, the law of the jungle still exists. ”

The current top-level combat power of the new human race is equivalent to a fleet of the old L3. At least, in terms of the quality of the flagship, it is no longer inferior to the L3 veteran civilization. It is only limited to the number of people, and the scale is far from sufficient.

Don't underestimate this, which L3 civilization hasn't gone through 10,000 years of development?!

The fact that the new humans were able to catch up in a short period of time is already quite a remarkable achievement......

Therefore, the L3 fleet already has a certain ability to protect itself.

From the perspective of cosmic warfare, it is easier to escape than to destroy, so L2 can fight L4 for a moment or two; L3 can fight back and forth with L4 without being easily crushed.

But also because of the intellectual barrier, once the civilization crosses over to L5, it is impossible to let the lower-level civilization take advantage of it so easily.

For example, an average person with an IQ of 100 can communicate with a genius with an IQ of 200.

But with 100 IQ, it is impossible to communicate with an alien with 1000 IQ.

Breaking through the intellectual barrier, 1000 IQ is already a qualitative change, just like the gap between orangutans and humans. Every question that a person thinks about is difficult for orangutans to understand.

This difference has led to the various technological weapons of L5 also becoming unbelievable, how can this be fought?

"How much can a civilization that has crossed the intellectual barrier improve its intelligence?"

This is the first doubt of the new human civilization, they don't know if they have crossed the ...... At least the superhuman mind is getting brighter and brighter the more you use it, and you still have a lot of potential.

"Forget it, we don't have to think too much about it for the time being, although the main civilization of the 'Amoeba Alliance' is advanced, but the members of the alliance, it's not easy to say." For the sake of safety, Yu Yifeng and others had a very detailed discussion because of this transaction.

"Even if it's an alliance, technology can't be shared."

"And...... The alliance generally implements a contribution system, and the scientific and technological strength of the members is not equal. ”

"So what we met this time may be a member of a lower rank."

It is for this reason that everyone has the courage to trade.

At this moment, Hei said in a tone of uncertainty that "It is said that this alliance only recruits ...... Members of amoeba are sapient beings of the mollusk class. Well, they certainly don't look great...... I mean, wouldn't it be very angry if, if all the newly born intelligent beings in the galaxy were affected into human form, and they couldn't recruit new members? ”

"So...... We should not expose our appearance in trading...... The province was unwarrantedly angry. ”

"Okay, that's for now." Yu Yifeng nodded.

For a civilization, any disadvantages should be raised in advance. In case some ancient civilization has a great hatred for humanoids, people can prevent it in advance, and the province will suffer a disaster for no reason.

In this way, the spacecraft returned one by one, and after two months of careful preparation, basically all the machinery had been carried back.

Almost all of the small ships, whether scientific or functional, are parked in a given position among the four large flagships.

The mothership "Homeland" has already been full, and a large amount of supplies are like mountains, rivers and seas, and if it is loaded again, it will only sacrifice the living space in the "Noah".

The other three main ships also kept stuffing stuff into it, as if they were going to fit the entire planet in.

Yu Yifeng looked at the resource report, his heart was extremely satisfied, he waved his hand, and said very generously: "...... Is there really no place for it? These few spaceships that are about to be scrapped, don't want them, stay in Mio 4. If the natives of Mio 2 can land on this planet, it will be a small reward for them! ”

The technology in the scrapped spaceship is more than a hundred years old, so don't want it.

The point is, the natives have to land on this planet, otherwise everything will be in vain.

The length of the mothership "Homeland" is 50 kilometers in total, which is slightly larger than the original Deep Space, but the use of a large number of nanomaterials and the use of controlled nuclear fusion technology instead of the cumbersome nuclear explosion furnace make it only one-third of the mass of the "Deep Space".

This means that the Homeland is more maneuverable and is also able to carry more items.

And the flagship of mankind, the most powerful combat weapon, should belong to the ...... "antimatter particle beam weapon".

This particle beam weapon uses "positrons" as a means of attack, and the speed of the projectile can be close to the speed of light, and if it encounters the "ion shield", it will undergo an annihilation reaction, resulting in a huge explosion.

Therefore, it is impossible for the ion shield to block this new type of weapon.

Of course, the ion shield is still a good shield technology. The principle is quite clear, simply put, it is to use dense high-speed ions, usually electrons or protons, under the action of a magnetic field, to form a dense ion wall.

These high-speed electrons can absorb lasers as well as various energy weapons, and the effect is quite good.

But unfortunately, so far, humans have not really completed the ion shield technology.

Because of its very high complexity and great technical threshold, it is necessary to spread the entire magnetic field on the surface of the spacecraft, and to make the number of electrons that can be distinguished by the naked eye, not only to let them move in a vacuum, but also not to let them run out, the difficulty and energy consumption can be imagined.

The new humans have been developed so far...... It is a simple version of the "Electromagnetic Shield", which is a simple version of the Ion Shield, and the magnetic field can deflect some weapons, but the density of the ions is relatively low, and the interception effect is average.

"It is always easier to destroy than to build, and a spear is always sharper than a shield. The shield technology can only bully the weak, and in the face of enemies of the same level, it is better to develop more powerful lethality! ”

Under the guidance of this thinking, the antimatter particle cannon, after years of research, has become the most powerful lethal tool at present, its huge energy consumption and complex structure, which can only be equipped on four large main ships.

Yu Yifeng stood in the captain's room, and the screen showed four mighty flagships, and the time was counting down second by second.

"Report to the captain, everything is ready, please instruct!"

"Let's go!"

With a command, the engines behind the ship began to work, bright ionic flames erupted, and four large flagships flew in one direction at the same time.

"I order, turn on the ion engine with all your might, the overload program will start after thirty seconds, and the load standard value will be pushed up to 300%!"

"Captain's Command ......"

The natives who were staying in Mio 2 suddenly looked at the sky in unison, and several bright white points of light appeared in the distance, leaving them puzzled.

The people don't know, but the government knows very well that these top leaders are celebrating with joy.

Mr. President, who was the leader, suddenly burst into tears: "Let's go, these decrepit people are finally gone!" ”

For more than a hundred years in a row, even fools have discovered anomalies.

When the president, ambitious in office, was told this huge secret by his predecessor, he almost peed his pants in fright. It turns out that the inexplicable deaths of previous presidents have happened so many strange and intractable things...... That's because of these......

Now, this piece of heart disease has finally been removed.

"Mr. President, it's not good, it's not good!"

"What's the matter? Your Excellency, you should know, this is great news for us. The president said unhurriedly, clearly in a good mood.

Suddenly, in the conference room, all the TVs and the Internet, the same video jumped out one by one, strange singing was loud, and several large spaceships were singing.

"What's going on?!" The president was shocked.

The tall middle-aged man didn't care about this, and said anxiously: "A video of Yufu 4 is going viral on the Internet. Reputedly...... There are several alien ships left there! ”

"What...... Hurry up and block the news ......"
