Human beings have their own limits, and if they want to surpass the limits, there is only one way to abandon their original weak **, that is, not to be human.

Either genetic modification or biomimetic mechanization.

There is no doubt that, for the time being, the second path is a little smoother and more suitable for human ethics.

In the whole process, there are a series of structures such as eyeballs, bones, limbs, internal organs, etc., and the strongest change is undoubtedly the auxiliary memory brain, which will be installed when the human fertilized egg forms an embryo and the brain develops in the initial stage. The whole principle is very complicated to say, and it has taken countless efforts from generations of scientific researchers.

Zhang Yuan obviously felt that he had become smarter, and he could even recall what he ate and what he said to someone on a certain day last week!

Just like today's conversation, he could have recited it exactly the same in a week's time, word for word!

In the past era, he could be regarded as a top smart person, but it was impossible to be like now, with ten lines at a glance and backwards like a stream.

Of course, if there are too many such innocuous memories, it can also become a painful burden.

What kind of food you eat on a given day, how long you take a shower on a certain day, in fact, it doesn't make much sense. If you constantly recall these boring contents, it will become a disease.

In order to avoid these negative effects, "complete memory" can be preserved for about a week, after which this part of the memory will slowly be forgotten and converted into a general fuzzy fragmentary memory.

Only memories that have undergone intensive repetition training will be recognized as important memories by the auxiliary brain and permanently preserved.

Memory, what an important thing...... When the assisted memory brain is truly realized, it has brought earth-shaking fusion to the whole society!

When human beings are learning, they actually spend most of their time repeating training to memorize the content.

In fact, this process of repetitive training is very boring, there is no way, and if you don't repeat it, you can't remember it at all. Many people hate learning because of this.

But now it's different, the repetitive process has been cut in half, and all that's left is to understand what has already been written down in your head. There is no doubt that it has increased the enthusiasm of human beings to learn.

The essence of human beings is to love to learn, or more so to like to "explore".

As a simple example, many people are able to study a novel game for a long time, and the process is actually learning.

Humans just don't like to repeat it back and forth.

When I played the game a lot, I found that there was nothing new, and I gradually became disgusted.

Therefore, under the influence of the great enhancement of memory, the process of repetitive training has decreased, the number of people who love learning has also increased a lot, and the intellectual level of the entire human civilization has also been raised to a higher level.

In addition to the biomimetic brain, there are many advances in bionics, and all organs in the body can be replaced, including the bones in the body.

Surgery for whole-body modification is all based on personal freedom, and there are not many people who choose this whole-body modification, but there are some signs of it.

Zhang Yuan believes that as long as this kind of personal transformation can be standardized and not modified indiscriminately, it doesn't really matter much. He himself was a relatively civilized person.

Secondly, of course, it is the change in the humanities, compared to the time when the Gliese 581g was just started, the self-confidence level of the whole society has obviously improved a lot.

On the one hand, because of the great increase in military strength, there was originally only one mothership, but now there are two, and the number and quality of the rest of the warships have more than doubled.

On the other hand, with more civilizations in contact, human beings are no longer afraid of extraterrestrial civilizations, and gradually develop their own civilization self-confidence.

Fear comes from the unknown, and if the unknown decreases and you find yourself past 99% of civilizations, there is actually nothing to be afraid of.

If you follow the experience of the old third-level civilization and the badit civilization, the strength of this fleet is already equivalent to the top "emperor-level fleet".

As long as the entire fleet does not run to fight near the home planet of a third-level civilization without opening its eyes, it is basically fearless near the cosmic strings.

After all, the fleets sailing near the cosmic strings are basically third-level civilizations, as well as second-level civilizations.

The fourth-level civilization already has curvature technology, and is no longer confined to the natural routes in the universe, but has a broader sky. According to the number of fourth-level civilizations and the frequency of activities, the probability of being able to encounter them directly is very small.

During the period of time that Zhang Yuan left, the Kunlun Mountain fleet also encountered five alien civilizations, four of which were low-level civilizations, and one was a third-level interstellar civilization that also sailed near the cosmic strings...... Something interesting happened.

When talking about this matter, Lu Tao said: "Is it a third-level civilization? Actually, it's not that interesting, at most it can only be said that they passed by and exchanged some information with each other. There are also 2 planets of low-level civilizations, which have been assimilated by high-level civilizations...... How can I say it, I am too weak to even have the power of cosmic diplomacy, and I have directly become a vassal of the rest of the interstellar civilizations, and it is impossible to resist. ”

"Our fleet is already close to the trading market, and it may be more than a decade before it reaches ...... The probability of encountering interstellar civilizations will also increase! Even the planets around here are all colonies, so I simply don't visit these planets and go straight to the trading market. ”

Speaking of this, Lu Tao made an expression that suddenly thought of something: "Oh, by the way, the relevant team of diplomats may be very large, there may be five or six hundred people!" There should also be a quota among young people, and the competition will be very fierce. Haha, are you interested? Although you are the youngest, if you add a little oil, you should be the most likely among us. ”

Zhang Yuan's expression moved slightly, which was something he cared about very much.

Returning to the real world, he always has to do something he likes, now he is not a captain, it's not bad to be a scientist, artists, writers and the like or forget it, he doesn't have any feelings about these things at all, no matter how many reincarnations he has experienced, he still doesn't feel too much, and if he is not interested, he is not interested.

However, these returning transcendents have no privileges, and they must show enough value to be part of the diplomatic team.

If he has privileges because he is a returnee from the virtual world, it is another kind of unfairness to others. The contribution to civilization in the past can only represent the past and prove his good qualities at the personal level, but he Zhang Yuan left the real world, after all, it has been four or five hundred years, and he has been out of the times for a long, long time, how can he directly be a leader to control the direction of civilization?

It's absolutely impossible!

Zhang Yuan pondered carefully for a while, going to the interstellar trading market is to buy science and technology to exchange information, it is not enough to rely on diplomats, there must be scientific staff officers of various categories. The easiest path, of course, is to engage in research in science and technology and become a scientific research representative. It's his old business anyway.

"So, study hard!"
