Human beings have their own limits. If they want to surpass the limits, there is only one way to abandon their original weakness, that is, not to be a human being.

Either genetic modification or bionic mechanization.

There is no doubt that at present, the second road is more smooth and more suitable for human ethics.

During the whole process, a series of structures such as eyeballs, bones, limbs and viscera have appeared. The strongest change is undoubtedly the auxiliary memory brain. When the human fertilized eggs form embryos and the brain develops initially, it will be equipped with relevant auxiliary memory brain. The whole principle is very complicated, and it has taken generations of scientific researchers countless efforts.

Zhang Yuan obviously feels that he has become more intelligent. He can even recall what he ate and what he said to someone one day last week!

as like as two peas in today's conversation, he can recite it exactly the same after a week.

In the past, he can be regarded as a top smart man, but he can't recite everything at a glance like he does now.

Of course, this kind of irrelevant memory, if too much, will also become a painful burden.

In fact, it doesn't make much sense what kind of food you eat on a certain day or how long you take a bath on a certain day. If you often recall these boring content, it will become a disease.

In order to avoid these negative effects, "complete memory" can be kept for about a week, and then this part of memory will be slowly forgotten and transformed into general fuzzy fragmentary memory.

Only after intensive and repetitive training, the auxiliary brain will recognize it as an important memory and keep it permanently.

Memory, what an important thing When the auxiliary memory brain is really realized, it brings tremendous fusion to the whole society!

When human beings are learning, they are training repeatedly for more than half of the time to memorize the contents.

In fact, this kind of repeated training process is very boring, there is no way, do not repeat and simply can not remember. Many people dislike learning.

But now it's different. More than half of the repetitive process has been cut off. The only thing left is to understand the knowledge that has been written down in my mind. There is no doubt that it improves the learning enthusiasm of human beings.

The essence of human beings is that they love to learn, or even "explore".

For a simple example, many people can study a novel game for a long time, and the process is actually learning.

Humans just don't like to repeat.

When the game played more, found nothing new, also gradually disgusted.

As a result, due to the great improvement of memory, the process of repeated training has been reduced, the number of people who love learning has also increased, and the intelligence level of the whole human civilization has also been raised to a higher level.

In addition to the bionic brain, there are still many advances in bionics. All organs in the body, including the bones, can be replaced.

The whole body reconstruction surgery is all based on personal freedom. Not many people choose the whole body reconstruction, but there are some signs.

Zhang Yuan believes that as long as this kind of personal transformation can be standardized, do not modify, in fact, it does not matter much. He himself is a man with more civilized ideas.

Secondly, of course, there are changes in the humanities. Compared with when we started from glitzer 581g, the confidence level of the whole society has improved a lot.

On the one hand, the military strength has been greatly enhanced. There used to be only one Mothership, but now there are two. The number and quality of the remaining warships have more than doubled.

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

Fear comes from the unknown. If the unknown is reduced and you find that you have surpassed 99% of civilization, there is nothing to be afraid of.

According to the experience of the old three-level civilization and badit civilization, the strength of this fleet is equivalent to the top "imperial fleet".

As long as the whole fleet does not go to fight near the parent star of a class III civilization, it is basically fearless near the cosmic string.

After all, most of the fleets sailing near the cosmic chord are of the third level civilization and the second level civilization.

The fourth level civilization already has curvature technology, no longer clinging to the natural routes in the universe, and has a broader sky. According to the number and frequency of the four civilizations, the probability of direct encounter is very small.

During the period of Zhang Yuan's departure, the Kunlun fleet also encountered five alien civilizations, four of which were low-level civilizations, and another was a third-level interstellar civilization that also sailed near the cosmic string Some interesting stories happened.

When talking about this, Lu Tao said, "third level civilization? In fact, it's not very interesting. At most, I just passed by and exchanged some information with each other. There are also two lower civilization planets, which have been assimilated by higher civilization How to say, it's too weak to even have the power of cosmic diplomacy. It directly becomes the vassal of other interstellar civilizations, and it's impossible to resist. ""Our fleet is close to the trading market. It may take more than ten years to reach The probability of meeting the interstellar civilization will be greater and greater! Even the nearby planets are not necessarily colonial stars, so we simply don't visit these planets and go straight to the trading market. "

Speaking of this, Lu Tao made a sudden thought of something: "Oh, by the way, the relevant diplomatic team may be very large, there may be five or six hundred people! There should also be places for young people. The competition will be very fierce then. Ha ha, are you interested? Although you are the youngest, if you add some oil, you should be the most likely one among us. "

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

To return to the real world, he has to do something he likes. Now he is not a captain. It's good to be a scientist. Let's forget about artists and writers. He doesn't have any feeling about these things. No matter how many cycles he has gone through, he doesn't have much feeling. He is not interested in them.

However, these returned elites do not have any privileges. They must show enough value to become a member of the diplomatic team.

If he has privileges because he is a returnee from the virtual world, it will be another injustice to others. The degree of contribution to civilization in the past can only represent the past and prove his good quality at the personal level. However, Zhang Yuan has been away from the real world for four or five hundred years. He has been away from the times for a long time. How can he be a leader to control the direction of civilization?

This is absolutely impossible!

Zhang Yuan pondered carefully for a while. He went to the interstellar exchange market to buy science and technology and exchange information. It's not enough to rely on diplomats alone. He must have all kinds of scientific advisers. The simplest way, of course, is to engage in scientific and technological research and become a scientific research representative. It's his old business anyway.

"Then, study hard!"
