In the months that followed, Ye Xing repeatedly tested hundreds of species of animals and plants, and it is unknown whether they will prolong their lifespans, but cell repair has really been achieved.

In fact, it has been found that the effect of plants is more obvious, and it may be that these active peptide extracts themselves come from various elixirs;

Animals can only change a certain characteristic after injection, and the cells in the body do not significantly produce more active peptides, and the active peptide content in the cells will return to normal after ten and a half days.

In other words, these changes are temporary, and eventually most of the active peptides are metabolized by the cells, and now the research question becomes how to stimulate the cells in the body to produce these active peptides on their own.

This is probably because the composition of the details is not completely consistent, or in other words, for animals, it is necessary to inject the active peptides extracted from similar animals.

Ye Xing immediately aimed the experiment at the giant python, there was a small group of giant pythons here, which should be the best experimental subject.

With Ye Xing's current cultivation in the Jindan Realm, it is not too difficult to deal with a giant python, but it is not easy to catch it and extract its blood as the object of extracting active peptides.

Of course, Ye Xing had a way, first prepared a special anesthetic poison for the giant python, made it into an injection needle, shot it into the body of a super-large python with a gun, turned the python numb, and then extracted a large amount of its blood;

Ten days later, two active peptides were extracted from the blood of the python and had a great effect on cell division, regeneration, and repair.

I found a small python to conduct an experiment, first of all, the small python was seriously injured, the whole body was damaged, and the time of automatic regeneration and repair was observed, and the result was that after 14 days, it was basically completely repaired, and there was no wound at all.

It can be seen that the python here, its cells are born with excellent repair ability, it is sure that there is a special place, the life of the general snake is only ten years, but look at the size of the python, its lifespan should be decades.

Then, Ye Xing beat the little python again into the same injury as last time, and then injected an active peptide solution ten times more concentrated, and as a result, after only seven days, the little python was completely repaired.

In the end, the same operation was done again, but in this injection, more active peptides extracted from plants were added, and a small amount of special active peptide extracts of blood color orchid were added, and the concentration of active peptides was 30 times that of the original.

The result surprised Ye Xing too much, the little python's injury was repaired in only one day, and in the following days, the little python continued to grow rapidly, and in less than a month, it grew more than twice as big as it was.

The cells of the python were compared, and it was found that not only could it heal wounds quickly, but its cells did not become senescent because of their size, and really completely changed the proportion of various active peptides inside their cells.

Ye Xing guessed that it should be the extract of the blood color orchid that played a key role, that is, the solution mixed with a variety of active peptides was the elixir of immortality that he was pursuing.

It's just that now it is necessary to conduct live experiments on humans, or animals that are close to humans, to verify their true effectiveness.

Of course, Ye Xing will not experiment with himself, one will not reflect the effect, and the other will not be stupid enough to experiment with himself.

With the consent of the white fox, Ye Xing asked the white fox to do the experiment, because the white fox is an animal that can practice, and it should have different effects.

Ye Xing mixed the active peptides extracted from twenty kinds of animals and plants together to prepare an injection similar to the body fluids of the white fox, but the various ingredients were more than ten times higher than the total amount in the body of the white fox.

The amount of injection is large, and there is a large bottle of mixed solution, which is carried out in the form of a hanging needle.

Ye Xing asked the white fox to practice while hanging the needle, and as a result, the white fox quickly fell asleep and fell into a deep hibernation.

Knowing that there would be no big problems, Ye Xing didn't dare to be careless, and kept staring intently, using his divine sense to control and measure the changes in the white fox's body.

The hanging needle lasted for seven days, and the white fox had been cultivating in a deep sleep, its skin and meridians were all reborn, and all its fur fell off and grew again.

Under Ye Xing's divine sense, the white fox's bones also underwent a slight reorganization, and its absorption of earth aura was significantly enhanced.

Of course, Ye Xing would not let go of the opportunity, and directly extracted the cells of the white fox in multiple locations every three days for comparative analysis.

The accumulated data was quickly plotted on the computer, and there were significant changes in the data, and the key active enzymes increased significantly.

For forty-nine days, the white fox in cultivation woke up, and now the white fox has completely returned to a young state.

After careful inspection, the current state of the white fox is the state of the fox clan when it was just an adult, that is, the white fox has been young for nearly forty years, that is, the white fox has been reborn.

After being reborn, the White Fox's qualifications have undergone earth-shaking changes, and its absorption and conversion efficiency of the Earth Spirit Qi has increased several times, reaching about 21%, which means that it has become a genius of Earth Spirit cultivation, and it should be a super genius.

You must know that Ye Li is such a genius, and the aura conversion efficiency is only about 15%, and Ye Xing has cleared the refining impurities through the Phoenix Fire Refining Technique, and his physique is transparent, and the aura conversion rate is only 12%.

And the white fox has now directly advanced to the peak of the innate ninth layer, and will soon break through to become the beast king.

Through his thoughts, Ye Xing taught the fox clan's cultivation techniques that had been re-derived by superintelligence to the white fox, and directly gave it dozens of top-grade earth spirit stones to break through the retreat.

Ye Xing called Ye Li and told the white fox about the situation, Ye Li was very excited, and the possibility of her appearance not getting old was greatly increased.

Of course, Ye Xing told her that she would not be injected until millions of human trials were conducted, and who knew what side effects would be?

Ye Xing knows very well that cells can divide and repair quickly, and if the slightest deviation is not controlled, it is a cancer tumor, this is not a joke.

Ye Xing decided to observe the real effect of the white fox while extracting a large number of active peptides, and also conduct quantitative experiments and analysis on other species of animals and plants.

Of course, the blood orchid was too scarce, and Ye Xing directly used a place with excellent aura in the swamp as a medicine garden, set up a formation, planted dozens of plants together, and used the method of asexual reproduction to divide and multiply into tens of thousands.

It's just that this kind of plant has a long growth period, so Ye Xing used the method of rapid cultivation of the culture medium, and then planted it in the medicine garden, hoping to accelerate its growth process.

After coming here for nearly a year, Ye Xing extracted a large amount of single active peptide solution, added ice spirit crystal solution and stored it in the space ring.

Ye Xing's cultivation has also improved slightly, the cultivation of the third layer of the Jindan Realm has increased slightly, and due to the long-term use of divine consciousness to analyze and monitor, he has also taken a large number of spiritual pills to restore divine consciousness.

The divine consciousness slowly recovered to the ninth layer of the Jindan Realm, and it was relatively condensed, within a diameter of three hundred miles, it could be easily scanned.

There are many kinds of brute beasts in the mountains and forests, but there are many more plant species, and within the scope of Ye Xing's divine consciousness, there are also flashes of spiritual light everywhere, indicating that there are many elixirs, and it also shows that the aura here is excellent.

Ye Xing really wanted to go to the bottom of the swamp to take a look, there should be a spiritual vein underneath, otherwise there would not be such an excellent aura, mainly water aura, but the earth aura was also quite abundant.

But Ye Xing didn't dare to dive underground, there were too many unknown dangers below, but there was no need to do it, anyway, he didn't lack spirit stones, of course, if it was a spirit crystal, it was necessary.

The spirit crystal is a thousand times purer than the best spirit stone, it is the crystallization of spiritual energy, there are no impurities at all, and there are only some in the space ring, and there is no outside world at all.

The retreat of the white fox, Ye Xing just accidentally probed it with his divine sense, and seeing that it was going well, he was completely relieved.

After two months of retreat, the white fox really advanced to the beastmaster, and the fur on his body was reborn again, and he looked a little younger.

The original cute and pleasing appearance has become extremely majestic, and if you let it move in the nearby mountains and forests, there is basically no opponent.

The white fox's combat power is not good, and it will definitely not be able to defeat those brute beasts, but the coercive momentum of its beast king still makes the nearby brute beasts dare not approach at all.

The cells of each part of the white fox were thoroughly analyzed again, and the results showed that the active peptide content that affected the cell life span and energy conversion in any part was directly more than three times that of the original;

And some special parts, such as meridians, nerves, acupuncture points, etc., seem to really change the mechanism of synthesizing active enzymes inside all cells.

Ye Xing decided that the white fox had really changed his physique, and the effect of forging his body with the Phoenix Refining Fire Technique was better, and it seemed that this method was feasible.

The White Fox injection trial seems to have been successful, at least for three months, and no adverse side effects have been found.

Ye Xing decided to return to Rouran, and large-scale human trials were needed to verify whether the injection was safe.
