In this way, under the careful promotion of Zhang Yuan's scientists, until the 30th year, almost all system vulnerabilities related to optical perception were patched completely.

About 1 in 10 Tothians have acquired visual perception through surgery. And this proportion of the population continues to grow. This cooperative experiment was of great benefit to both civilizations, with the Thoth civilization gaining what it had been longing for, and the humans being rewarded with a great deal of money, as well as valuable work experience.

This work is not done in vain, the extra-dimensional perception laboratory led by Zhang Yuan, the scale of talents has expanded to 690, this is a group of very experienced and very capable teams, even if there is no Zhang Yuan, the core figure, there are a lot of work can be carried out independently. This is a normal laboratory.

The current focus will gradually shift to the research of "pseudo-humans", that is, a link before strong artificial intelligence, plus the improvement of additional perception, which is basically enough for everyone to be busy for a while.

"How's going on with the Thoth civilization? It seems that there has been no feedback for several days. ”

On this day, Zhang Yuan asked a diplomat.

"Okay! I guess I'm playing with my phone, let's take a look? ”

The Toth civilization is indeed a very adaptable race, and it only takes a month or two for them to be able to adapt to the movement of visual conditions in the first stage. It takes three to five years to be able to fully adapt.

And once they get used to optical perception, they will find that the original perception is really a bit uncomfortable and lacking. Mobile games have become their new toy, ahem, it seems a bit of a stretch!

All in all, these Tothians, who have gained visual perception, treat Zhang Yuan, a great scientist, with fanatical admiration as if they had seen reborn parents. Every time Zhang Yuan visited the experimenters who had undergone surgery, he would receive a series of ceremonial treatments.

Even Captain Feng of the new human civilization has less than half the status of Zhang Yuan!

This situation made Zhang Yuan very embarrassed, not because of his high status, but because those etiquettes were too troublesome, just standing there in a daze, that is, meditating for an hour or two, the longer the meditation, the better, who can stand it if there are more times!

“…… Respect for the new human civilization, our friendship with each other is as wide as the Milky Way! But I have to say, we have to go back. ”

"Our biggest goal this time is optical perception, and now, this discipline has been completely matured. After more than ten years of trial, it is difficult for us to find the defect again, and we have deeply understood its convenience. ”

"We want to pass on this new technology to the base camp in the rear as soon as possible, and we have been longing for the light for 40,000 years. It's hard to describe what it feels like in this way until you really have it, it's really hard, and our greatest saints, can't describe what it's like to be light. ”

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

The leader of the Tothians kept praising Zhang Yuan's team, and even wanted to kidnap them alive.

Digging out a skylight in the back of your mind is definitely a real difficulty!

The scientists within the Torth civilization are not stupid, they have been discussing it for a while, and they still feel the difficulty of it, and it is still not enough to give them another 40,000 years.

All in all, a rapprochement between the two sides is certainly inevitable.

As for the huge price paid by the Toth 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 the Toth civilization, there is no big problem with the problem of visual imaging for now. The only difference is that there are only two colors in your world, black and white, but in reality, there are many more colors in this world. ”

That is, the three primary colors in the conventional sense, that is, red, blue, and cyan. With these three colors, more colors can be combined. ”

So, the next thing to do is to form a perception of the colors in your mind. I'll give you information about the extra colors for the new humans. But the brains of the individuals of the two civilizations are different, so there is no way to be completely universal. ”

Adding color is an extra job, so humans aren't going to do it for them, and it's up to the Toths to update themselves.

After all, with each new color added, the workload increases considerably. Whether it can be upgraded successfully or not, people will not care, this job has consumed the youth of so many scientific research workers......

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

And for the Toth civilization, it is enough to be able to distinguish black and white eyes, which are a thousand times better than before. Blindly adding color is likely to cause cognitive disorder in the brain, so use it like this first.

As for the subsequent upgrading and development, of course, you have to rely on yourself, not blindly rely on others. They also know that between civilizations and civilizations, the most important thing is interests. If the relationship between the two sides is good, then we must help each other and maintain a long-term friendship, instead of sticking it on with a dead face, picking up sesame seeds and losing watermelons.

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

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

First, the curvature technology of both sides broke through to 3 times the speed of light, and then stuck.

There is a relatively large threshold here, which cannot be crossed for a while and a half, and it may take a long time to accumulate experience before it can be gradually improved.

Regarding planetary curvature technology, there has also been some progress, but it has also been stuck in a certain link. At its core, there is a very complex mathematical problem, which cannot 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.

The current military strength of the new human civilization, striking at a third-level civilization, is a real hanging! Even if the opponent has a battle star as its backing, humanity can win at the cost of almost zero casualties.

After breaking through the light barrier, the trail of the curvature spacecraft will become difficult to capture, and the opponent can't even catch it, so how can it be shot down?

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

It has been discovered that wars between fourth-level civilizations and fourth-level civilizations are still rare. Because if you want to escape from the war, it is not too easy!

One general described in his work report: "...... However, we believe that the possibility of a clash of fourth-level civilizations will become more common than that of third-level civilizations. Yes, war is still not easy to break out, but compared to the third-level civilization stage, the probability is much greater. ”

"Three-level civilization, the two sides deter each other, and if you can't fight, you often can't escape."

"Fourth-level civilization, the side that attacks first has a great first-mover advantage."

"On the defensive side, the disadvantage is very big."

"If there is a real war, it is likely that the winner will be decided in a short period of time."

Except for the "curvature missile" capable of exceeding the speed of light, no weapon can catch up with the curvature ship.

But in the vast universe, where are the curvature missiles launched? Can the hit rate reach 1 in 10,000?

It is very difficult that the current curvature missiles of mankind can only hit high-speed targets within a distance of 2 light minutes, and this target must have obvious traces of movement, such as emitting strong light, or emitting strong infrared rays.

Otherwise, the missile's hit rate will plummet.
