Different from Su Wuming's teachings, the energy system of the Iron Egg Star has become a basic theory after countless years of development, although this set of theories does not involve the rank above the saint level, but it has extremely important guiding significance for the basic training and advancement.

As a lecturer at a famous university in the human continent, Lu Xun's explanation of this basic discipline is undoubtedly very realistic, which makes Zhao Yun feel a sense of being forced to popularize science.

In Lu Xun's explanation, the energy that can be used for cultivation is actually diverse, Lu Xun stretched out ten fingers to indicate a lot, after thinking about it, he felt that it was not right, the energy in his body flowed, and the earthy yellow energy light simulated more and more fingers on his entire arm, making people feel immediately epiphany and extremely mad.

In this regard, Zhao Yun is not difficult to understand, this is like earthlings can eat fruits, rice or meat to replenish the body's energy, but in different ways, the utilization rate of energy is different.

In the history of the Iron Egg Star, some people cultivated light wave energy, some people cultivated spiritual energy, nuclear energy, and many more. If ranked by power, those who cultivate elemental energy may only be ranked in the middle rank.

But after countless years of survival of the fittest, now they are basically cultivating elemental energy, because elemental energy can be positively stacked.

When a strong person above the saint level cultivates, the soul will draw energy in the void, and after these energies and elemental energy are fused, they become a special energy that can accommodate the will of the saint level or the will of the Xuan level, which is the key to the fact that the saint level and the Xuan level can fight hundreds of heavenly levels at a time.

And this fusion process will overflow a large amount of elemental energy into the space. In layman's terms, one soul energy + one elemental energy = 0.5 saint-level energy + 1.5 spillover elemental energy.

As a result, as the number of people cultivating elemental energy continues to increase, the higher the concentration of elemental energy in the Iron Egg Star, the easier it is to cultivate elemental energy, and even ordinary people are slowly evolving in this positive cycle, their bodies become stronger, their lifespan is increased, and they are also more adapted to elemental energy cultivation, and the proportion of people who can cultivate elemental energy per 10,000 people is several times that of people in other energy systems.

In the end, the cultivators of the other energy systems were either killed or had no successors, and gradually withered.

After hearing this, Zhao Yun's eyelids jumped, and he couldn't help but guess that this matter was probably a big game of chess under the Heavenly Dao of the Iron Egg Star based on the plot of a large number of fantasy novels read by people in the two lives, of course, this is just this simple YY.

Elemental energy also has the advantage that it can be used as a conventional energy source for technological development. This is very easy to understand, the house that Zhao Yun bought was charged by him. And no other energy can achieve the universal interaction between cultivators and external objects, just like the Flash returned to the age of steam, and he couldn't even light a kerosene lamp with his own electric energy.

Therefore, the development of elemental energy technology has achieved the industrial revolution of Iron Egg Star, and the dream of "science and technology is the primary productive force" that a certain time-traveler has been holding since his mother's womb has been shattered into slag.

Lu Xun briefly introduced the advanced nature of elemental energy, and then began to talk about the key content of cultivation and rank.

The so-called cultivation, for example, earthlings who eat meat will be converted into fat in the body to store energy, and then decomposed into energy when needed, but all this is automatic and cannot be interfered with.

But one day, someone invented a method that can actively stimulate the breakdown of fat into energy, and then control this energy to repair cells, defeat viruses, strengthen the body, and make all fat people become winners in life, which is cultivation.

And to improve the rank, that is, the fat man above learned to cultivate, groped out the best line to use fat, and finally one day, the body was strengthened to the limit, and there was nothing else to do, so he began to strengthen his brain without fear of death.

Some fat people are unlucky, and their brains are strengthened into paste, and some are lucky, and when their brains really become stronger, they can secrete a strange blend of hormone enzymes and elemental energy.

After blending, the energy will generally have a five-fold increase in quality, and the physical limit that could not be improved can be further improved with the help of higher quality energy.

If the fat man who is lucky enough to record these strengthened patterns, it will become a cultivation exercise, and the people behind him will not be easy to practice according to the map.

As for bottlenecks, just like normal people have a defense mechanism that will pass out if it hurts too much, the brain will also have a defense mechanism for strengthening the brain, and if you can't break through, you will never be able to strengthen it.

For example, if a person is in a coma after producing grade 6 pain, this is the original defense mechanism. After that, he was able to endure 10 levels of pain, which is to break the bottleneck.

On the Internet of Iron Egg Star, there are a huge number of basic exercises, so most people in this world can try to cultivate, but most people can't break through the bottleneck, so they can only spend a hundred years as ordinary people.

And the lucky ones break through the bottleneck and enjoy a longer life.

The above popular science content is applicable to any level, but after the holy level, there is a soul that cannot be explained by science, this guy can draw energy in the void, and then fuse with hormone enzymes and elemental energy, turning the original ordinary energy into energy with a certain will, and even producing some stunt-like effects.

It can be said that the holy level is a watershed, and the distinction is clear and thorough. It is not only the strength that is divided, but also the logic of cultivation.

Below the holy level, the brain can only control its own energy operation, whether it is in the body or the energy is released, anyway, it is one's own ability to control, so cultivation is like absorbing water, creating a pressure difference in the body so that the elemental energy from the outside world is attracted and assimilated into its own energy in the body.

But after the holy level, the unscientific soul can directly control the elemental energy near the body, and then the cultivation becomes water injection, directly allowing the elemental energy to go wherever it wants.

Speaking of this, Lu Xun snorted and said, it's not scientific, it's not scientific, the soul is not scientific, and the strong are not scientific, and the look of blowing his beard and staring at him made the students silent.

However, Zhao Yun listened to it with relish, he came from the earth, and he has always been in awe of the mysterious elemental energy, at this time, he was forced to popularize science, and the two lives were recognized by people, and the sense of mystery was greatly reduced, but there was a sense of pride standing on the shoulders of scientific giants on two planets.

However, what Lu Xun said next directly made Zhao Yun fall into the second dimension of confusion.

Lu Xun is talking about a famous experiment in the history of the past hundred years, the experiment of external force through the brain evolution, yes, in Zhao Yun's ears, it is Su Wuming's nameless divine art scientific version.

The experimental process was similar to what Zhao Yun experienced, except that there was no washing of tendons and marrow. An ordinary person, according to a feasible line, constantly infuses the brain with energy, so that the brain continues to advance to produce higher levels of hormone enzymes, even to the point of the meta-level.

But the result is very bad, the mortality rate is 99.99%, and one of the experimental subjects who is still alive has become a Xuan-level vegetative person with cerebral palsy, well, it is still a vegetative person who can't move and can't think.

Therefore, the Pavilion of the Gods, which oversees the five major biological races of all continents of the Iron Egg Star, issued a solemn statement that it is not feasible to use external forces to penetrate the brain or only strengthen the brain when cultivating, and asked the people of all ethnic groups not to try it, and even asked all ethnic groups to list in the "Peace Convention of All Ethnic Groups on the Continent" that they will not conduct such experiments again.

Well, Zhao Yun knows that the Heavenly Pavilion is equivalent to the United Nations with the combined national strength of the United States, China and Russia, but he doesn't know this statement and doesn't know what the "Peace Convention of All Ethnic Groups on the Mainland" is, Su Wuming doesn't know or not, but the result is definitely not managed, Zhao Yun can only be afraid, thank his shit luck and save a small life.

But Zhao Yun thought about it again, maybe the difference in this experiment was the inhumane washing of muscles and marrow, now Zhao Yun is not only successful in the experiment, the brain has evolved to secrete saint-level hormone enzymes, although he still can't sense any soul or void energy.

In the process of strengthening the brain with the energy in his body, Zhao Yun has always felt that his brain is improving, but his body is seriously depleted, until he finally evolved to the holy level, but he was horrified to find that his body was on the verge of collapse, but fortunately, at this time he gained the ability to freely control the secretion of hormone enzymes.

According to Zhao Yun's conjecture, the physical potential of washing the muscles and marrow was greatly consumed when the earth-level heaven-level and even saint-level energy began to circulate in the body, and without this ability to regulate, Zhao Yun's body would definitely be wiped out in the high-quality energy flow.

Fortunately, Zhao Yun obtained this adjustment ability for unknown reasons, he can secrete the corresponding level of hormone enzymes according to the strength of his body, so as to strengthen his body again, and now, he is strengthened to the level of a high-level warrior, and he also has the ability to burst the seed of the saint-level energy, but I don't know if the body can withstand it.

Secretly assessing his own situation, Zhao Yun turned his mind back to listen to the lecture with mixed feelings, and suddenly remembered that there was a thing I didn't know just now, what the hell is the "Peace Convention of All Ethnic Groups on the Mainland"?

"What is the Peace Pact of All Ethnic Groups on the Mainland?"
