The robot quickly delivered octopus kebab and added some side dishes.

Zhang Yuan ran to the kitchen enthusiastically and prepared some special sauces. In those difficult times in the past, even eating something delicious became a luxury...

Even though Zhang Yuan’s reincarnation has a very good birth, the final outcome will always be in a mess, which is also a choice for him.

Just thinking about this, he sighed softly.

The changes in the times are too big.

The entire sauce configuration didn't take much effort. On the way, he had already used human chips to send relevant information and prepared these seasonings.

"Try it!"

"Okay, I just called and called my two sisters over. They are very busy at work and don't look for boyfriends. I don't know what they are doing all day long..."

Since everyone has implanted the auxiliary brain in the embryonic stage, everyone has become very smart, and both learning and memory abilities have changed drastically than before.

The existence of the brain also changes all aspects of life, including the use of some electromagnetic waves to achieve human-computer interaction.

In principle, the auxiliary brain will only accept the electrical signals of the human body itself. Humans still have to rely on their eyes to see, ears to hear, and body to feel, so that they can obtain perception of the outside world and cannot directly receive electromagnetic wave information in the air.

This is to consider security issues, so that a single electronic virus will not paralyze humans.

However, the human brain cannot receive electromagnetic waves, but it does not affect the transmission of electromagnetic waves to the outside. Nowadays, people usually implant a human chip at the back of the neck. As a brain wave reading device and an electromagnetic wave generator, many tasks are just thought about and then used to send electromagnetic waves, and the robot can work for it.

But don’t underestimate this. Whether it’s typing on a computer, controlling power armor, or drawing drawings, the calculations are countless times simpler!

Human work efficiency has been greatly improved, and many complex tools are no longer needed to be used to fiddle with hands like before.

For most humans today, there is no problem. Everyone has a good memory, and it becomes a very simple thing to restore the pictures in their minds to the computer.

Of course, there is still a distinction between people and mediocrity. Zhang Yuan’s class is the so-called “elite class”. He jumped directly for several years and jumped to university. The university basically studied in the original postgraduate and doctoral students.

In order to avoid wasting talent, everyone will classify and train according to their own preferences after middle school education and determine the next research direction. Only in this way can they adapt to the huge scientific and technological tree of the third-level civilization with a small population.

Zhang Yuan adapted to the entire new era and couldn't help but sigh: "Since humans invented the auxiliary memory brain, they have completely stood firm in the heels of the third-level civilization and fully understood the huge technology tree... It's really not easy. Four or five hundred years ago, it was still very advanced technology to convert brain waves into pictures, and only those with extreme concentrations of attention can do it. But now, children can do it easily!"

"But it is still a bit difficult for a population of 20 million to fill all the technology trees, so each population will basically engage in intellectual activities and subdivided them into a certain direction, so that the waste of human resources can be reduced..."

Just as we were chatting, two beautiful young ladies sat next to them, "It's really rare to see us in a century. Oh, your sauce is really good... The grilled octopus is so delicious!"

Zhang Yuan grinned. He was two sisters in the same small family. The younger one was named Zhao Congcong. He was five years older than him. He was a very lively girl.

The oldest one is Hua Yun, who is seven years older than him.

Zhao Congcong scolded him with a smile: "Zhang Yuan, don't say so many serious things all day long, human beings will always get better and better. Don't keep your head open and read books all day long, without saying a word. How can you find a girlfriend like this? You are already 18 years old."

"Yes, it's so serious all day long. But today I seem to have been a lot of excitement... It's too early to find a girlfriend, and I'm still very young at the age of 18!"

Hua Yun's thoughts are much more traditional than Zhao Congcong. She believes that humans should focus on learning before the age of 50, because before the age of 50 is the best time to learn.

Zhang Yuan was a little embarrassed by being discovered by others that he was a little embarrassed, "No, no, no, I just lamented that the society is not easy to make progress. It seems... it seems to have made progress for no reason. It seems easy, but in fact it has been a long time."

Yes, for Zhang Yuan, it was indeed making progress for no reason.

Just eating and drinking, drinking and eating, everyone was very happy to get together. Zhang Yuan still likes the feeling of staying with his family very much. Even though his mental age is much older than these three people, who doesn’t like to stay with young people?

Lu Tao next to him, he is crazy about recommending the latest "bionic artificial cornea" launched by Amway.

It is also a simple corneal surgery, which replaces the original cornea with a bionic cornea.

Bionics technology is becoming more and more powerful now. Various bionic devices can directly use blood sugar as energy source, and there is no need to replace batteries or other troubles.

After installing the latest cornea, human vision will become better and you can see things in dark light.

"...You can even see bacteria! You know, there are mites on human faces, especially those campus goddesses' faces, but there are mites on their faces!"

The two girls were shocked and almost scared to death by him. One of them even hit him.

"…and then, this function has been temporarily banned because it caused everyone's discomfort."

Lu Tao talked about this aspect and became more and more excited. "Although the function of bacteria in human eyes has been realized long ago, just installing electronic eyes... But now integrating this function into the cornea is still a very impressive achievement. Zhao Congcong, do you go for an operation?"

Zhao Congcong quickly shook his head: "Let's talk about it then, I'm not myopia now... Haha, I'm a little scared. However, if it helps the experiment, I really have to consider it."

She is engaged in biological research and is still a graduate student. It is quite helpful if she can see bacteria without using a microscope...

Isn’t the reason why human society has progressed because of the increasing development of tools?

Zhang Yuan smiled. What he cares most about is of course what changes have taken place in the past few hundred years since he left, whether in science and technology, history, or humanities. This change can be easily experienced from every bit of life.

"It seems that the research on bionics has been quite successful and has penetrated into all aspects of life... This is a good thing!"
