Humans have their own limits. If they want to surpass their limits, they only have one way to abandon their originally weak ones, which means they will no longer be human.

Either genetic modification or bionic mechanized modification.

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

During the entire process, a series of structures such as eyeballs, bones, limbs, and internal organs appeared. The strongest change was undoubtedly the auxiliary memory brain. When the human fertilized egg forms an embryo and the brain develops initially, it will be equipped with relevant auxiliary memory brains. The whole principle is very complicated and it takes countless efforts from generations of scientific researchers.

Zhang Yuan obviously felt that he had become smarter. He could even recall what dishes he ate and what he said to someone one day last week!

Just like today's conversation, he could recite it exactly in a week, without a word!

In the past, he was considered a top smart person, but he could not be like now, with a look of ten things and memorizing them like the flow.

Of course, if there are too many such irrelevant memories, they will also become a painful burden.

What kind of dishes did you eat on a certain day and how long did you take a bath on a certain day actually have little meaning. If you often recall these boring content, it will become a disease.

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

Only memory after intensive repeated training can assist the brain recognize it as an important memory and be preserved permanently.

Memory, what an important thing... When the auxiliary memory brain is truly realized, it brings earth-shaking fusion to the entire society!

When humans learn, they actually spend most of their time repeating training to memorize the content.

In fact, this repetitive training process is very boring. Is there any way to do it? I can't remember it without repetition. Many people hate learning because of this.

But now it is different. The repeated process has been cut off by half, and the rest is only understanding the knowledge that has been recorded in my mind. There is no doubt that it has enhanced human enthusiasm for learning.

The essence of human beings is actually to love learning, or it can be said to like "exploration".

To give 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 it back and forth.

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

Therefore, due to the significant enhancement of memory, the process of repeated training has decreased, and the number of people who love learning has increased, and the intellectual level of the entire human civilization has also been raised to a higher level.

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

The surgery for whole-body modification is all based on personal freedom. There are not many people who choose this whole-body modification, but there are also some signs.

Zhang Yuan believes that as long as this kind of personal transformation can be standardized and not randomly modified, it actually doesn’t matter much. He is a person with relatively open minded thoughts.

Secondly, of course, there are changes in humanities. Compared with the fact that when we just started from Glitzer 581g, the confidence level of the entire society has improved significantly.

On the one hand, because of the significant increase in military strength, there was only one mothership, but now there were two. The number and quality of the remaining warships were more than doubled.

On the other hand, as more civilizations come into contact with, humans are no longer afraid of alien civilizations, and gradually develop their own civilization self-confidence.

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

If we follow the experience of the old third-level civilization and the Badit civilization, the strength of this fleet is equivalent to the top "imperial-class fleet".

As long as the entire fleet runs to the home star of a third-level civilization without open eyes, they are basically fearless near the cosmic string.

After all, most of the fleets sailing near the cosmic string are third-level civilizations and second-level civilizations.

The fourth-level civilization already has curvature technology, no longer sticks to the natural routes in the universe, and has a wider sky. According to the number and activity frequency of the fourth-level civilization, the probability of directly encountering is slim.

During the period when Zhang Yuan left, the Kunlun Mountain Fleet 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... Some interesting stories happened.

When talking about this, Lu Tao said, "Is the third-level civilization? Actually, it's not interesting. At most, I can only say that I pass by each other and exchange some information. There are two planets of low-level civilizations that have been assimilated by high-level civilizations... How to say it, it's too weak and has no power for cosmic diplomacy. It's directly a vassal of other interstellar civilizations, and it's impossible to resist."

"Our fleet is approaching the trading market, and it may take more than ten years to reach it... The probability of encountering interstellar civilization will become increasingly greater! Even the nearby planets are not necessarily all colonial stars, so we should not visit these planets and go straight to the trading market."

Speaking of this, Lu Tao made an expression of suddenly thinking of something: "Oh, by the way, the relevant diplomat team may be very large, there may be five or six hundred people! There should be quotas among young people, and the competition will be very fierce at that time. Haha, are you interested? Although you are the youngest, if you add fuel, it 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, you have to do some career you like. Now he is not a captain, and it is not a good idea to be a scientist. Forget it, artists, writers, etc., he has no feeling about these things at all. No matter how many reincarnations he has experienced, he still doesn’t have much feeling. If he is not interested, he is not interested.

However, these extraordinary people who returned have no privileges. They must show sufficient value to become a member of the diplomatic ranks.

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

This is absolutely impossible!

Zhang Yuan thought about it carefully for a while and went to the interstellar trading market to buy technology to exchange information. Diplomats alone are not enough. He must have various categories of scientific advisers. The simplest path is of course to engage in scientific and technological research and become a scientific research representative. Anyway, it is also his old profession.

"Then, study hard!"
