The Kunlun realm has developed for nearly 4,000 years now, and the former Kunlun Divine Ruins have been restored by the efforts of generations of cultivators, and most of the areas have been transformed like fairylands.

The entire Kunlun realm tends to be the same under the concept that everyone can cultivate the truth, and the goal of human beings is to set the goal of the next conquest in the endless sea of stars, and I believe that this will open a new era of turbulence!

And Lin Fei is the most dazzling genius of this era!

Being able to advance to the Yuanying realm at the age of less than sixty was not only the fastest cultivation speed in this era, but it was also unique even in the entire Kunlun Realm's four thousand years of history! Not to mention, Lin Fei was also a compound cultivator!

Even in this new era with tens of billions of cultivators, the number of compound cultivators is not much, if you can't understand what is special about compound cultivators, you just need to know that the Venerable Tianxuan, known as the "Father of the New Century", is a compound cultivator!

A peerless genius like Lin Fei, there were too many auras shrouded in him, if it weren't for the accidental explosion of the Mustard Seed Laboratory, God knows how far he would have been able to grow?

Now, Lin Fei has unexpectedly returned to his youth, what does this mean? Does he want to relive his life again?

No matter how powerful a character is, it is impossible to say that there are no regrets in life, and Lin Fei will naturally be no exception. So, as a former genius, if you can live again, you must be able to be even more amazing, right?

Moreover, was the explosion in the mustard lab really just an accident?

As a party to Lin Fei, of course he knows the truth of the facts, if he wants to live a more exciting life, then he must completely take his fate into his own hands and never make the mistakes he made again!

With a lot of thoughts in his heart, the expression on Lin Fei's face gradually became resolute, and his hands were clenched into fists, obviously making up some kind of determination!

After a while, the expression on Lin Fei's face relaxed, and he returned to his normal appearance as a delicate young man. If an acquaintance saw Lin Fei at this time, he would definitely not notice anything abnormal, and he didn't know that in this young Lin Fei's body, what was actually alive was the soul of more than forty years later!

Although Lin Fei, who grew up, has the reputation of a genius, he is a real orphan, and the reason why he can support himself and grow up is that he has the special ability of different pupils.

Lin Fei's heteropupil has the ability to be called "subtle", and he is born with the ability to see extremely subtle changes clearly, if he cultivates this subtle pupil to a high and profound realm, he can even reach the level of observing things and entering the atomic structure!

Lin Fei in the previous life was regarded as the new hope of the Xiuzhen civilization, and the news of his retreat to study the new secret treasure always affected the stock market of the entire Kunlun realm, because he had a subtle pupil, he was the greatest refining master of this era!

Being able to see the subtleties that ordinary people can't see, so that all the magic weapons that have been refined by Lin Fei's hands are all high-quality, and this is just one of the extraordinary skills he has as a compound cultivator.

If Lin Fei didn't really have something extraordinary, how could he become a genius cultivator who was well-known throughout the Kunlun Realm?

When Lin Fei was a teenager, when he had not yet emitted the most brilliant light, the only thing that could make him have a certain degree of popularity was the faint pupils!

You must know that even in this new era of national cultivation, not everything can be placed in the sun, and there are also gray areas such as the underground world, which also makes some unsightly transactions exist in almost every large city, and the young Lin Fei lives in such a place.

He has subtle pupils, he should be a refiner by nature, and he only needs to refine some contraband that is officially prohibited from circulating in the market, which can be exchanged for enough wealth for him to protect his life, even if Lin Fei is now restricted by cultivation, and he can't refine anything too high-end, but it is enough for him to make a name for himself in the underground black market.

It can be said that Lin Fei, who will become famous in the future, is completely a black history at the beginning of his start, but the more this is the case, the more it shows that he is valuable, and it is also conceivable how much price he has paid on the road of growth!

The first turning point in Lin Fei's life came from the unified examination of Xiuzhen Academy to be held soon, and he stood out in this exam known as the "New Era College Entrance Examination", so that he was qualified to enter Xiuzhen Academy, receive systematic study and cultivation, and finally soar to the sky!

As for the moment, Lin Fei, who has not yet reached the age of sixteen, has been at the bottom of society, and for the time being, he can't see how much he will achieve in the future.

Lin Fei in the previous life was already the top genius in the Kunlun realm, and now that he has the opportunity to live again, how amazing will the light he exude be?

The experiment that was almost completed before the Yuan Infant blew itself up should be able to be realized in advance in this life, right?

But the lesson of blood told Lin Fei that the news related to it must be strictly prevented from leaking, and it is impossible to publicize it with as much fanfare as in the previous life!

After all, the research of nanoparticles is too rebellious, it can fundamentally change the quality of a cultivator's spiritual energy, so that every cell of the human body can hold more spiritual energy, which is enough to instantly increase the strength of a cultivator by several times or even ten times!

As the old saying goes, Sumeru is in mustard seeds, describing that extremely large things can be contained in extremely small things, and the nanoparticles studied by Lin Fei have the power of mustard seeds!

Transforming the human body through nanoparticles can be so subtle that it can open up space in every cell, so as to accommodate more psionic energy and make the operation of psionic energy more efficient!

This is a cross-era feat of combining ancient cultivation methods with modern technology, if Lin Fei's research is really successful, the impact on the entire human society will be even stronger than the spiritual root gene liquid invented by the Heavenly Xuan Venerable!

In the last life, Lin Fei had been in retreat for nearly five years, and he was about to gain something, but in the end, because this research was too rebellious and affected too many interests in all aspects, this made the mustard seed laboratory have an "accident", and Lin Fei had to blow up the yuan baby and burn the jade!

As soon as he thought of this, Lin Fei felt hatred: those people who were short-sighted, only thinking about their own interests and losses, completely ignoring the development and evolution of the entire human society, actually secretly poisoned at the most critical moment, which led to a failure!

If it weren't for this "accident," the nanoparticles would have been successfully studied, right? Even if it was only a primary product, Lin Fei was sure that through the transformation of nanoparticles, the spiritual energy of human cells would be increased by as much as two to three times.

As long as we continue to improve in the future, the multiple of improving our ability will definitely get bigger and bigger, which will be of great benefit to the entire Kunlun Realm, and I am afraid that I will not be able to conquer the Endless Star Sea when the time comes?
