In this way, under the careful promotion of Zhang Yuan's scientists, almost all the loopholes in the system of optical perception were repaired until the 30th year.

About one in ten TOS have visual perception through surgery. And this proportion of the population is still growing. This cooperative experiment is of great benefit to both civilizations. The TOS civilization has obtained what it has long wanted, while mankind has received a lot of remuneration and valuable work experience.

This work is not done in vain. The super dimensional perception laboratory led by Zhang Yuan has expanded the talent scale to 690. This is a group of very experienced and capable teams. Even without Zhang Yuan, there are a lot of work that can be carried out independently. This is a normal laboratory.

At present, the key work will gradually shift to the research of "pseudo human", that is, a link before strong artificial intelligence, coupled with the improvement of additional perception, it is basically enough for everyone to be busy for a while.

"What's going on with the TOS civilization? There seems to be no feedback for several days. "

On this day, Zhang Yuan asked a diplomat.

"Good! I guess I'm playing with my cell phone. Let's go and have a look. "

The TOS civilization is indeed a very adaptable race. It only takes a month or two for them to adapt to the movement under visual conditions in the first stage. In three to five years, we can fully adapt.

Once they adapt to optical perception, they will find that the original perception is a little uncomfortable and lacking. Mobile games have become their new toys. Cough, it seems a little far away!

In short, these TOS who have obtained visual perception worship Zhang Yuan as enthusiastically as they see their reborn parents. Every time Zhang Yuan visits the experimenters who have finished the operation, he will receive a series of etiquette treatment.

Even captain Feng of the new human civilization is not half as high as Zhang Yuan!

This situation makes Zhang Yuan very embarrassed. It's not because of his high status, but because the etiquette is too troublesome. Just stand there in a daze, that is, meditate for one or two hours. The longer the time of meditation, the better. Who can stand more times!

"... dear new human civilization, our friendship is as broad as the Milky way! But I have to say, we have to go back. "

"Our biggest goal this time is optical perception. Now, this discipline has completely matured. After more than ten years of trial, it has been difficult for us to find defects and deeply understand its convenience. "

"We want to impart this new technology to the rear base camp as soon as possible. We have been longing for light for 40000 years. Before we really have it, it's difficult to describe the feeling in this regard. It's really difficult. Our greatest sage can't describe the feeling of light. "

"Once you have light, you never want to lose it..."

The TOS leader kept praising Zhang Yuan's team and even wanted to abduct these people alive.

Chiseling out a skylight in the depths of my mind is definitely a real difficulty!

The scientists in the TOS civilization are not fools. They have discussed it for a while, still lamenting the difficulty, and still can't give them another 40000 years.

In a word, it is inevitable for both sides to make friends.

As for the huge price paid by the TOS civilization - value, absolute value!

In this meeting, after the leader finished speaking, it was Zhang Yuan's turn to speak. He cleared his throat and said: "Friends of TOS civilization, there is no big problem about visual imaging at present. The only difference is that there are only black and white in your world, but in fact, there are more colors in this world. "

"That is, the three primary colors in the conventional sense, namely red, blue and cyan. More colors can be combined through these three colors. "

"Therefore, the next work is to form the cognition of various colors in your mind. I'll give you the information about the additional colors of the new humans. But the brains of the two civilized individuals are different, so there is no way to be completely universal. "

Adding color is equivalent to extra work, so humans do not intend to help them do it. They need TOS to upgrade themselves.

After all, every time a new color is added, the workload will increase a lot. Whether it can be upgraded successfully or not, people will not care. This job has consumed the youth of so many scientific researchers

Even if the two sides have established a very deep friendship, it is impossible to arrange everything completely, which will take hundreds of years.

For the TOS civilization, such an eye that can distinguish black and white is enough. It is a thousand times better than before. Blindly adding color is likely to disorder the brain's cognition, so use it like this first.

As for the subsequent upgrading and development, of course, we have to rely on ourselves, not blindly rely on others. They also know that the most important thing between civilizations is interests. If the relationship between the two sides is good, we should help each other and maintain long-term friendship, instead of sticking it up, picking up sesame and losing watermelon.

Besides, in case you can't get an upgrade, you still have to rely on Zhang Yuan and others.

Therefore, the next meeting will summarize the progress of cooperation between the two sides in the past 30 years and look forward to the future development direction: of course, the most important thing is a series of transactions brought by "optical perception". In addition, there are many scientific cooperation.

First, the curvature technology of both sides broke through to three times the speed of light, and then got stuck.

There is a relatively large threshold here, which can not be crossed in a moment and a half. It may take a long time to accumulate experience before it can be gradually improved.

There has also been some progress in planetary curvature technology, but it is also stuck in a certain link. Its core is a very complex mathematical problem, which can't be forced for a while and can only be stopped.

Second, after a large number of military exercises, the military has formed a multi-level attack mode with ultra-high mobility as the core.

With the military strength of the new human civilization, attacking a three-level civilization is a real hanging attack! Even if the other side has a war star as its backing, mankind can win at the cost of almost zero casualties.

After breaking through the light barrier, the trace of the curvature spacecraft will become difficult to capture. The other party can't even capture it. What's the reason for shooting down?

On the other hand, after long-term research, high-sensitivity lidar, electronic jamming and some antimatter weapons have made a series of breakthroughs.

It is found that the war between the fourth level civilization and the fourth level civilization is still rare. Because it's not easy to escape from the war!

A general described in his work report: "... But we believe that the possibility of conflict between level four civilizations will become more common than that of level three civilizations. Yes, war is still not easy to break out, but the probability is too much higher than that of the third level civilization. "

"Three levels of civilization, the two sides deter each other, but they often can't escape."

"Level Four civilization, the party that launches the attack first, has a great first mover advantage."

"The defensive side has a great disadvantage."

"If there is a war, it is likely to win or lose in a short time."

Except that the "curvature missile" that can exceed the speed of light can break through the speed of light, no weapon can catch up with the curvature spacecraft.

But in the vast universe, where are curvature missiles launched? Can you hit one in ten thousand?

It's very difficult, very difficult. The current curvature missile can only hit a high-speed target within a distance of 2 light minutes, and the target must have obvious movement traces, such as strong light or strong infrared.

Otherwise, the missile's hit rate will drop sharply.
