The robot quickly delivered the octopus skewers, plus some side dishes.

Zhang Yuan ran to the kitchen with great interest and made some special sauces, and in those difficult times in the past, even eating a little delicious became a luxury......

Even if Zhang Yuan has a very good birth in every reincarnation, the final ending will always be tossed upside down, which can be regarded as his own choice.

Thinking so, he sighed softly.

The times have changed too much.

It didn't take much effort to configure the entire sauce, and on the way, he had already used the human chip to send relevant information and prepare these seasonings.

"You taste it!"

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

Since everyone has been implanted with an auxiliary brain at the embryonic stage, everyone has become very intelligent, and both learning ability and memory ability have changed dramatically compared to the past.

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

In principle, the auxiliary brain will only receive the electrical signals of the human body itself, and human beings still have to rely on their eyes to see, ears to hear, and body to feel in order to gain perception of the outside world, and there is no way to directly receive electromagnetic wave information in the air.

This is to consider the issue of safety, so that an electronic virus will not paralyze humanity.

However, the human brain cannot receive electromagnetic waves, but it does not affect the external emission of electromagnetic waves. Nowadays, people usually implant a human chip in the back of the neck, as a brainwave reading device and electromagnetic wave generating device, many jobs as long as you think about it, and then use this chip to send electromagnetic waves, and the robot can work for it.

Don't underestimate this, whether it's typing on a computer, manipulating power armor, or drawing drawings and calculations, it's all countless times easier!

The efficiency of human work has been greatly improved, and the use of many complex tools no longer needs to be played with by hand as in the past.

For most of humanity these days, nothing is a problem. Everyone's memory is very good, and it becomes a very simple thing to restore the picture in your mind to the computer.

Of course, there is still a distinction between people who are smart and mediocre, Zhang Yuan's class is the so-called "elite class", and he skipped a grade for several years and jumped to the university, where the content of the original graduate and doctoral students is basically the original.

In order to avoid the waste of talent, after secondary education, everyone will be classified and cultivated according to their own preferences to determine the next research direction. In this way, with a small population, it can adapt to the huge scale of the third-level civilization.

Zhang Yuan adapted to the whole new era, and couldn't help but sigh: "Since the invention of the auxiliary memory brain, human beings have completely stood firm on the heels of the third-level civilization and eaten through the huge scientific and technological tree...... It's really not easy, four or five hundred years ago, converting brain waves into pictures was still a very, very advanced technology, and it required extremely focused people to be able to do it. But now, kids can do it easily! ”

"But with a population of 20 million, it is still a bit difficult to fill all the technology trees, so every population will basically engage in intellectual activities and subdivide them into a certain direction, so as to reduce the waste of human resources......"

In the middle of chatting, two beautiful young ladies sat next to them, "Actually invited us to eat, it's really rare to see in a hundred years." Ah, your sauce is really good...... Grilled octopus is so delicious! ”

Zhang Yuan grinned, they were two sisters in the same small family, the younger one was called Zhao Congcong, who was five years older than him, and was a very lively girl.

The eldest is called Hua Yun, who is seven years older than him.

Zhao Congcong counted him down with a smile on his face: "Zhang Yuan, don't talk about so many serious things all day long, human beings will always get better and better." Don't bury your head in reading books all day long, don't say a word, how can you find a girlfriend, you are 18 years old. ”

"yes, so serious all day long. But I seem to have opened up a lot today...... It's too early to find a girlfriend, 18 years old is still very young! ”

Hua Yun's thinking is much more traditional than Zhao Congcong's, and she believes that human beings should focus on learning until the age of 50, because before the age of 50 is the best time for learning ability.

Zhang Yuan was a little embarrassed when others found out that something was wrong, "No, no, no, I just feel that social progress is not easy." It seems like...... It seems to have progressed for no reason, and it seems easy, but in fact, it has been a long, long time. ”

Yes, for Zhang Yuan, it is indeed progress for no reason.

Just eating, drinking, drinking, eating, everyone was very happy together. Zhang Yuan still likes the feeling of staying with his family very much, even if his mental age is much older than the three of them, but who doesn't like to stay with young people?

Lu Tao next to him, I don't know what's going on, is crazy about Amway's latest "biomimetic artificial cornea".

It is a simple corneal surgery that replaces the original cornea with a biomimetic cornea.

Nowadays, biomimetic technology is becoming more and more powerful, and various biomimetic devices can directly use blood sugar as an energy source, and there is no need to replace batteries and other troubles.

With the latest corneas, humans will be able to see better and see clearly in low-light environments.

“…… You can even see bacteria! You know, there are mites on people's faces, especially on the faces of campus goddesses! ”

The two girls were startled and almost scared to death by him, and one of them even hit him.

“…… Then, this feature was temporarily banned because it caused everyone's discomfort. ”

Lu Tao talked about this aspect, and the more he talked, the more energetic he became, "Although the function of bacteria has long been realized with the human eye, as long as an electronic eye is installed...... But now integrating this function into the cornea is quite a remarkable achievement. Zhao Congcong, will you go for an operation? ”

Zhao Congcong hurriedly shook his head: "When the time comes, I don't have myopia now...... Haha, I'm a little scared. However, if it is helpful for experiments, it is really worth considering. ”

She's a graduate student in biology, so it would be helpful if she could see bacteria without the help of a microscope......

Isn't the reason why human society has progressed because tools are becoming more and more developed?

Zhang Yuan was smiling, what he was most concerned about was, of course, what kind of changes had taken place in the Kunlun Mountain society in the hundreds of years since he left, whether it was in science and technology, history, or humanities. This kind of change can be easily experienced from every bit of life.

"It seems that the research on bionics is quite successful, and it has penetrated into all aspects of life...... That's a good thing! ”

Zhang Yuan does not reject self-transformation in this regard, this is one of their original plans, and now it seems that it has been completed very well by the generations of leaders behind them.
