The progress of biotechnology research is very slow, and many biochemical processes are fundamentally different from many of the knowledge of the premortal earth, and need to be re-simulated with the help of computers.

Of course, today's computer capabilities are limited, especially the speed is really not good, and most of the work still has to be handled by quantum intelligence;

It's just that quantum intelligence consumes extremely large amounts of true qi, and Ye Xing doesn't dare to let it use his true qi so wantonly all the time.

After a year of experimentation and computational reasoning, there were still discoveries, especially about the possibility of slowing down cell division and cell aging.

The role of mitochondria in cells is actually the role of biological enzymes, and Ye Xing decided to extract or formulate a biological enzyme drug from other organisms to test ways to slow down the aging of cells.

It's just that this must be an experiment of nearly hundreds of billions, and it is impossible to do it, so it can only be deduced by the method of calculation and simulation, and handed over to the superintelligence to slowly deduce.

After more than a year of painstaking research and comparative experiments, but there were no substantive results, Ye Xing was not disappointed, things were not in a hurry.

Although he could be contacted at any time, he hadn't returned to the East for a long time, Ye Xing wanted to relax, so he took Qin Xinyue and the three children back to the East.

Ye Li must also follow, and she does not want to stay alone in the Royal Academy.

When he came to the second base, the plane was filled with aviation kerosene refined by the oil base, and dozens of large barrels were placed in the storage bracelet, and Ye Xing drove the plane back to the east.

There was no stop along the way, and after 20 days, the family returned to Xuanyuezong, and this time they came back, and the two children who had been out for more than three years returned to the grassland.

Ye Xiaozi and Ye Xiaoming's cultivation has improved somewhat, and they have both reached the peak of the fifth layer of foundation building, although it is only a small level of progress, but their families and the two masters are very satisfied.

The key is that the two of them have been out for more than three years, hiding their cultivation, pretending to be ordinary people, and traveling to dozens of countries in the East, not to mention anything else, their knowledge and mentality have matured a lot.

After three years of training, the two juniors of the Ye family are not hard, but they have seen some things in the outside world, especially the difficult survival of the people of other countries, so that the two of them have a new understanding of the Heavenly Star Country and the country created by their fathers.

The parents who paid blood, sweat and hardships for the Tianxing Country, abandoned all the glory and interests, and lived a hard life, but they stayed in the prairie to train successors for the country, and they were unknown for a lifetime.

The two little ones couldn't face all this calmly, they felt that their family's efforts were not respected.

No one in the outside world knew about it, especially since all the school textbooks in the Celestial Star Kingdom did not talk about the great contribution of their parents.

Every time, when they see other people's wanton spending and extravagant life, they don't have much money themselves, and they are unwilling.

But it also gave the two juniors of the Ye family a new understanding of their parents, Qi Ming, and Xuanyue Sect.

I have been educated since I was a child that I am the guardian of the Celestial Star Country, but I don't know what the Celestial Star Country is, why should I protect it? What is the purpose of repair?

In the three years of going out, I have seen the birth, old age, sickness and death of many people, the difficulties of ordinary people's livelihood, and I have also intersected with other cultivators;

There was even a time when he fought with others to the death, but fortunately the two of them had spirit guns, otherwise it would be really troublesome.

The two really have some insight, and gradually understand their parents' thoughts, away from the hustle and bustle of the world, so that their family does not have to fall into the hardships of survival, and has a broader freedom of life.

Cultivating the truth is just to get rid of the limitations of some ordinary people and pursue greater freedom in life.

Xiuzhen is not a broken heart, there is also human affection, there are also strife and conspiracy, everything is not taken for granted.

Ye Xing, Zi Jiu and Gu Zhen were also very satisfied with the experience of the two of them, and gave them a lot of elixirs, so that they could prepare for retreat and advancement after a little adjustment.

Since Qin Jingxuan had obtained the activation of the Wood Divine Blood, the absorption and conversion efficiency of the True Qi in the meridians had been significantly improved;

With the use of the best wood spirit stones, after more than a year of retreat, it has truly advanced to the seventh layer of the foundation.

Now that Qin Jingxuan is consolidating her cultivation, she doesn't have to retreat, and because of the two children's homecoming, she was teleported back from the small valley, and the whole family reunited for the first time in three or four years.

In this reunion, of course, the happiest is Mother Ye, a nearly ninety-year-old lady, who is still clear-headed and quick in action, which makes the family feel very at ease.

After testing the cultivation of each person in the Xuanyue Sect, all of them have not made much progress, and some of them are old, so to be honest, there is not much chance.

Even if Qi Ming's qualifications are very good, the progress is not ideal, mainly because he has too many foreign affairs.

This time, Ye Xing decided to bring Qi Ming to Rouran as well, and the Xuanyue Sect was mainly managed by the Qin sisters, with two Supreme Elders, and the others were experienced people, so it should be no problem.

Ye Xing also once again had an in-depth understanding of the teaching situation of Xuanyue Sect, and made relevant detailed adjustments to the existing problems.

The first batch of children after the new education reform have graduated and left, and they will first be arranged to serve in the Tianxing Army for a period of time, and then they will enter the institutions at all levels of the Tianxing Kingdom according to their interests and strengths.

It is not clear what the effect will be now, but these people are all talents who have received ten years of training in the latest technology, and they should be very powerful, Ye Xing is confident, but he is not in a hurry.

Ye Li wanted to recall dozens or hundreds of people to assist Rouran in her reform plan, but Ye Ran refused, because the first batch of talents still had to be observed for a few years, and the Heavenly Star Kingdom was to be entrusted with a heavy task.

Xuanyue Sect has another batch of freshmen who have been training for half a year, and Ye Xing has a detailed understanding of more than five hundred children one by one, and for the only three children with good qualifications, he has taught the cultivation of the true exercises.

After staying in the grassland for twenty days, Ye Xing took Ye Li, Ye Ran, and Qi Ming and returned to Songcheng;

Ye Xing and Qi Ming first met the old brothers in Songcheng, and they were very happy to see each other, the two of them were still the same as when they were young, and everyone else was gray-haired.

Ye Xing also met the new president, Ye Qingyan, who retired from the military at the age of 63 and immediately participated in the presidential election, and with the support of all parties, he was elected only by a narrow number of votes.

In fact, the top hundreds of capital tycoons in the Tianxing Kingdom are all from the Donghai family, and with their financial resources and public opinion, they can still control who they want to support to be elected.

Ye Xing didn't have any thoughts about this, everything was reasonable and legal, and of course he was happy, because the old brother was still in control.

He thinks that there is no problem, as long as they still take care of the people's livelihood, are still developing science and technology, and abide by the law, it is fine, there is no perfect system in the world.

Ye Xing went to the headquarters of the "Nighthawk" and once again inspected the progress of various new technologies under research, especially the new developments in computer technology and communications.

With Ye Xing's practical design plans and advanced knowledge ideas, everyone only needs to refine the goals and carry out continuous experiments, and the progress is still satisfactory.

Ye Xing's main focus is still on the new development of software, network and ultra-long-distance communication technology, and Tianxing Kingdom is building a new backbone communication network throughout the country.

Ye Li and Qi Ming also went to visit the Computer College in the attached city of Songcheng, and the first batch of more than 1,000 computer professionals trained have been enriched to local departments at all levels in Tianxing Kingdom.

The college also offers short-term training courses, mainly to popularize the use of computers, which are now attended by many people, and also offer evening classes.

After Ye Xing and Ye Qingyan discussed, they asked to open a computer school in every county in the country to speed up the popularization of relevant knowledge, and also allow talents from non-Tianxing countries to come to study, but they had to charge higher tuition.

In the end, Ye Xing came to the military base more than 100 miles away from Songcheng and conducted the most detailed and precise inspection of the jet high-speed aircraft in the test flight.

The engine and fuselage frame are forged with ultra-high-strength titanium alloy, and the skin is made of ultra-light aluminum, which can withstand high temperatures of more than 4,000 degrees brought by 4 times the speed of sound.

The ultra-high-speed engine is basically mature, and the efficiency ratio is as high as 15, that is, the thrust of the engine is 15 times its own weight.

The slender and streamlined fuselage requires a lot of fuel, and the interior space is greatly reduced, and the space for 50 people is planned to be sitting, and in the end there can only be 20 people.

For the time being, it is for military use, and high-speed and large travel is the core, so the design is appropriate, but not for civilian use.

From the memory of the superintelligence, Ye Xing found the tail of the engine and carried out infrared suppression technology, noise reduction technology, and immediately started to transform it.

He personally flew many times by plane, and Ye Xing analyzed various problems with engineers and technicians and provided solutions, all of which were technical solutions obtained from superintelligence.

For the safety of the aircraft itself, Ye Xing put forward new requirements for the painting of the aircraft, reduced reflections, and took matters into his own hands to set up hidden arrays in many places on the fuselage, so that the fuselage showed the color of the sky when flying.

This stay was more than 30 days, and Ye Xing cooperated to solve thousands of various small problems before it came to an end and froze all the aircraft technical solutions.

Finally, after another twenty days of detailed transformation, the aircraft finally had the performance that Ye Xing expected.

Ye Xing and Qi Ming accompanied more than a dozen engineers and technicians to get on the jet plane and conduct a long-distance flight test for several hours, and the whole flight was supersonic throughout.

Except for the sonic boom caused by supersonic speed, which is difficult to completely eliminate, the others can be said to meet Ye Xing's requirements, of course, continuous improvement in details is eternal.
