At this time, Li Jie, who entered the "Helios", was already standing quietly in the isolation room on the outer layer, the second protection in front of him was opened, and he walked in until he passed through the special alloy door on the third floor again, and then entered the innermost annular vacuum chamber.

That's right, in order to simulate it as much as possible, it is a full vacuum environment, and if you change to an ordinary human being, of course, you can't survive, but for Li Jie now, the physical body has long surpassed the need for ordinary oxygen.

After entering the legendary life, the control of entropy energy can be said to have reached an unimaginably powerful level, and the direction of each legendary demon's own evolution will gradually shift from the physical body to a more internal and esoteric part.

This part is called the soul by humans, and the soul magnetic field is called by the demons, and Li Jie prefers to call it the soul origin.

Of course, in Li Jie's view, this is just a title, and it doesn't matter what the title is, what matters is the soul itself. In essence, it should be regarded as the origin and core of all life. The only difference is that the existence of this primordial core has so far been completely elusive and uncertain for human beings, and the vast majority of people even believe that it is completely illusory, exists only in people's imagination, or at least has no physical form.

The reason for this is that human beings have no concept of perception and the origin of the soul, and the excavation and understanding of their own potential remain at a very primitive level.

The demons are more familiar with it, Li Jie is undoubtedly in his heart, the soul origin is the true mystery core of life, and it is by no means the so-called no substantive body, but the form of this origin core is too mysterious and wonderful. Beyond the cognition and understanding of the vast majority of life.

At the time of the first formation of life. The soul origin can be said to be a chaotic mass in perception. Vague and extremely fragile, it only becomes brilliant and powerful as the ontology of life grows, indescribably wonderful as a galaxy of spinning.

At this stage, in the demon world, it usually indicates that the demons have begun to actively contact and master the origin core, which will run through the entire process of evolution from low-level demons to middle and upper levels, and it is also the stage of soul origin awakening.

However, it is only after entering the legend that the inner part of the soul origin begins to enter a more peculiar transformation. It may even appear in various forms as the ontology consciously tempers and controls it, and this stage is also the process of life evolving from transcendent legends to immortality.

In the common understanding of the higher demons, this crucial stage is generally called soul formation.

The so-called soul shaping, of course, is not only a simple form change, but also the strength and evolution of the soul origin, which requires itself to continuously introduce more energy through entropy energy conversion for tempering.

To use a figurative metaphor, the soul source is like a seed buried deep in the body, and energy is the water, sunlight and nutrients that water the growth.

It's just that this wonderful seed has an unimaginable appetite, and it often takes a long time to get it to take root and bear fruit. The seed itself is not indestructible. As a gardener, the body must be cared for with utmost care. can wait until the day when the final fruit breaks through the ground.

In fact, in the sinking abyss, the demons did not need to worry about the absorption of energy too quickly and harming the soul origin, because it was a chaotic, dark, unimaginable world, energy was always a scarce resource, and even the sun overhead was hazy to the extreme. If we use the human concept of time to describe it, there are about 37 hours in a day in the world that has sunk into the abyss, but the sunrise time is less than one-tenth, which is converted to less than three hours.

Therefore, demons often have to go through hundreds of epochs (1 epoch is about 127 years), or even longer, before there is a slight possibility of breaking through to the Immortal Master, just a trace.

But now that's all changed completely.

The human world is so wonderful for the demons that the sun, rain, and all kinds of natural energy sources are simply an endless treasure that can be found naked and ready to be harvested, enough to shorten their evolutionary journey many times over.

Li Jie has no doubt that as long as he maintains his current state, no more than a thousand years at most, he can return to the peak and cast immortality. But if there are more convenient conditions and resources that can shorten the process even further, then why not?

Moreover, he also has an unknown sense of urgency.

Human beings' understanding of their own evolution is extremely backward, so crude that they are inferior to primitive creatures, but their understanding of the macrocosm and microcosm has reached a considerable level, and they can even use the resources on Earth to create terrifying energy such as nuclear fusion.

This is the root cause of the emergence of the current Helios Laboratory, and after an in-depth discussion with Steve, Li Jie signaled that he would spare no effort and invest countless financial resources to build this vacuum laboratory, so that he could go further and touch the "sun" more closely!

The most important point is that through the gradual maturity of the peripheral auxiliary heating and neutral beam injection system, the degree of this energy output can be controlled within a certain range, which provides infinite possibilities for Li Jie's soul origin tempering.

With his current level of evolution, of course, he can't really touch the core energy of the sun, and the tens of millions or even hundreds of millions of degrees of ultra-high temperature and endless hydrogen-helium nuclear reactions are completely beyond what Li Jie can withstand now, and it is enough terrifying energy for him to be completely annihilated.

Although all human beings are accustomed to seeing and accustoming the existence of the sun hanging overhead, few people have really understood the central celestial body of this solar system, the source of much matter and life on Earth.

The Sun is the only persistent and luminous celestial body in the entire galaxy, with a volume of more than 1.3 million times that of the Earth, composed of a solid sphere inside, an outer atmosphere and the troposphere between the two, and the deepest core is a nuclear reaction zone composed of hydrogen and helium, with a temperature of up to 15 million °C.

What Helios can currently simulate is only the photosphere in the solar atmosphere, that is, the circle of the sun's photosphere that can be seen by the naked eye in normal conditions, located outside the solid sphere and troposphere, and the lowest layer of the solar atmosphere, with a temperature between 4,500 degrees Celsius and 6,000 degrees Celsius.

Such a wonderful environment is the most suitable for Li Jie to transform energy and temper and strengthen the soul origin at this stage.

What appeared in front of Li Jie was a silver vacuum chamber covered by a large dome.

The interior of these alloy buildings made of high-temperature resistant special coatings has a special cold and heat cycle, and at the back of the chamber wall, it is composed of a huge superconducting toroidal field coil wrapped in a special material, and these polymetallic oxides are all high-temperature superconducting materials maintained at more than minus 200 degrees Celsius.

Simulating the sun's environment, even the hottest solar photosphere, is an extremely complex and dangerous process.

With today's human technology, it is not difficult to heat an object to 10 million or even hundreds of millions of degrees Celsius, but the difficulty is to keep it in a stable, controlled, and continuous state at this temperature, and to heat a large amount of matter to this temperature in a short period of time.

Matter is made up of atoms, which in turn are made up of the nucleus and electrons outside the nucleus. The so-called nuclear fusion is to free the electrons outside the nucleus from the shackles of the nucleus under certain conditions (such as ultra-high temperature and high pressure), so that multiple lighter nuclei (such as hydrogen isotopes deuterium (dāo), tritium (chuān), etc.) can attract each other and collide together, and the nuclei will polymerize with each other and fuse to form new heavier nuclei (such as helium).

And in such a wonderful nuclear fusion process, a huge amount of energy will be released.

The interior of the sun is constantly undergoing the process of hydrogen fusion into helium, which is the source of its endless light and heat. And the so-called hydrogen bomb of mankind is actually just the fusion of deuterium (an isotope of hydrogen) into helium. Because hydrogen fusion is much more difficult, the explosion of a hydrogen bomb is only a moment, while the nuclear fusion reaction of the sun is more complex and long. Over the course of billions of years, it has continued to happen.

This is the essence of the problem - a life span that is much longer than that of human beings, so that Li Jie clearly understands a truth: only the power that can be controlled is his true power.

Why has humanity built a nuclear bomb but still can't achieve controlled nuclear fusion? It is nothing more than that the reaction of a nuclear bomb is only an instantaneous explosion, and the purpose of controlled nuclear fusion is to control the duration and scale of fusion.

Can you imagine using a nuclear bomb to charge the lights and devices in your life?

Apparently not.

As a simpler example, lightning is very energetic, reaching billions to hundreds of billions of watts of electrical energy at temperatures of 10,000 to 20,000 degrees Celsius. Why can't the trees and human bodies that were hit be completely vaporized?

Because the duration is too short and the scale is too small, the instantaneous burst of lightning often lasts only a few thousandths to a few tenths of a second, and it dissipates instantly before it even has time to produce more reactions.

Human beings claim to have been able to create hundreds of millions of degrees of heat, even dozens of times more than the core of the sun, why did they not destroy the earth? Because it is at most a collision of tiny particles on the microscopic level, like a match that ignites in an instant, never trying to illuminate the whole world.

The purpose of the existence of the "Helios" ashram is to use these countless tiny sparks to gather together to create a room-sized ball of sunlight. (To be continued......)
