Outside Bianliang City, in an attic built and excavated by the martial arts master himself.

Huo Tianxiao pushed Wang Dong and walked in, with Lin Lingsu behind him, Guo Haihuang was still training the group of Great Song Forbidden Army to prepare for the future.

"Not bad, so let's get started."

With a wave of his hand, one by one the instruments were taken out of the storage soul guide carried by Huo Tianxiao and equipped into this attic.

The metal plates inscribed on the core circle are inlaid on the four walls, ceilings and floors, and they naturally glow with the supply of soul power, providing illumination, while purifying the interior to ensure the sterility of the laboratory.

All kinds of research instruments are neatly stacked, and there are experimental tables, experimental utensils, measuring tools, etc...... The entire attic is transformed into a modern research laboratory, and there are even two small generator sets for the power supply.

"Is this the method of the extraterrestrial man?"

Lin Lingsu looked at Huo Tianxiao's method curiously, like a mythical sleeve, the sun and the moon in the pot, which was naturally very attractive to him, a person from the Dao Sect.

"I'll get to know that later."

Huo Tianxiao didn't explain too much, he was already immersed in the brand-new experiment.

Correlation experiments of soul power and internal force.

Huo Tianxiao and Lin Lingsu were not chatting in vain before, and he had a deeper understanding of the so-called internal force, so as to decipher the reason why he and Wang Dong could not cultivate internal force.

Internal force, which can also be called true qi, is mostly commensurate with true qi, meaning life vitality, and practicing internal force is to practice one's own life vitality and enter immortality.

The so-called internal force is condensed by the essence of the human body, which is the product of the transformation of blood and qi, and a person seeks strength inward to obtain a kind of biological life energy, which has all kinds of incredible power.

To put it simply, it means that a person refines the essence of the water valley and the blood qi of the body through the practice of exercises, circulates them in the energy circulation channel called the meridians, and collects them into the dantian.

The essence of Mizutani is the essence of the day after tomorrow, the body energy replenished through food, and the cultivation of internal force transforms the essence of Mizutani, so people who practice martial arts often eat a lot of food, and it is normal for the kind of situation in the novel where a few catties of meat are eaten.

One of the reasons why ginseng is called a treasure of heaven and earth is that it contains a large enough essence of water valley, and it is easy to absorb, and often a single ginseng can increase its internal strength for several years.

After talking about internal power, then let's talk about soul power.

Soul power, the energy core of the soul master system, is the basic driving force of everything, based on the fundamental energy of the birth of martial souls.

There is a core element in the formation of this energy, that is, the martial soul, and the soul power must be present in order to be born, because the soul power is an energy based on the martial soul.

By absorbing the vitality of heaven and earth, breathing and exhaling, circulating in the meridians in the body and thus entering the dantian, it is born with the martial soul as the foundation, and this energy has a certain martial soul nature from the beginning.

The soul power of the sword martial soul is often sharp, the soul power of the healing martial soul is often full of vitality, the soul power of the thunder and lightning martial soul can be slightly electrified, and the flame soul power can be burned, and the temperature is not low.

From this, it can be seen that there are even two concepts between internal force and soul power.

One seeks inward, and the essence of the water valley and the blood and qi are transformed.

One is the vitality of heaven and earth, breathing and breathing, based on the birth of martial spirits.

One is peaceful, longevity and longevity.

One has different attributes, and many soul masters have lived past a hundred years old.

No matter how you look at it, soul power is another kind of energy that is stronger than internal force, it is a more expensive product, and it is also extremely restrictive, based on the birth of martial souls, which is really too restrictive.

But in the discussion, Lin Lingsu's words made him care a lot.

Similar but different, a little more rhyme?

Huo Tianxiao believes in his judgment, in this world, Lin Lingsu's intuition and ability are extremely powerful, and he can be said to have a world as a backing in the sense of heaven and man, and the unity of heaven and man. In other words, it can also be said that the world feels that soul power is similar to internal power.

Combined with the previous experiments, the death row prisoners on death row were born of internal power through the cultivation of Xuantian Gong, while Huo Tianxiao and Wang Dong had nothing, but their soul power had increased a little.

They don't have the mechanism to generate internal forces?

No, although there is this possibility, Huo Tianxiao doesn't think this is the right answer, compared to soul power, the birth mechanism of internal force is really simple, and there is no need for martial souls and other things that are not universal.

Well, there is only one answer.

"Sure enough."

After a series of data calculations and practice modeling, Huo Tianxiao made a note in his notebook.

"It's not that there is no internal force birth mechanism, but that the soul power birth mechanism overrides the internal force birth mechanism."

"After the essence of Mizutani and the flesh and blood qi were refined and transformed, they were changed by the martial soul, thus forming a new soul power. In a sense, the internal force has been cultivated, but it has always been soul power. ”

It may be a bit tongue-twisting, but it's actually quite simple.

The birth mechanism of internal force is very simple, the essence of water valley + blood and qi, after refining, it naturally becomes an internal force, which is a very people-friendly life energy.

In fact, there has always been a mistake in the birth mechanism of soul power, that is, it is not the Heaven and Earth Yuan Qi + Martial Soul, but a time of energy + Martial Soul, Heaven and Earth Yuan Qi, the essence of the water valley, and blood qi, these one-time energies are converted into soul power through the refining of the martial soul, that is, Huo Tianxiao has used N times of energy.

The martial soul itself is the core of the soul power birth mechanism, which belongs to a higher level in the current cognitive energy birth mechanism, and naturally covers the low-level internal force birth mechanism.

The origin of Xuantian Gong is relatively extraordinary, it itself is not a simple water valley essence, blood and qi refining means, it involves a certain degree of heaven and earth vitality absorption, so it is also applicable on the Douluo Continent.

Its essence is the extraction of primary energy, and the final secondary energy, because of the existence of the advanced conversion element of the martial soul, naturally changes from internal force to soul power.

"So the question is, is there an absolute difference between the two?"

Absolute differences.

After argumentation, soul power and internal force are a kind of secondary life energy with different birth mechanisms, and the birth mechanism of soul power is of a higher level, but it does not mean that it is a completely different kind of energy.

To investigate the rest of the essence, in fact, to eliminate the influence of the nature of the martial soul, soul power and internal force are considered to be an isotopic product.

"It turned out to be clear that it didn't."

Xuantian Gong is obviously a pure martial arts exercise, and I don't know why, there has been no sign of localization for so many years, at first glance, it is original, this kind of martial arts internal force cultivation method can be applied to the cultivation of soul power, and it has been proved that there is no absolute difference between soul power and internal force, otherwise, this Xuantian Gong will not be able to achieve a Tang San.

“…… So, the world is becoming more and more valuable. After thinking about some of the things in the intelligence, Huo Tianxiao's smile became a little weird.
