After the battle with Zixun, Qin Xuan returned to his residence in Daoshan Mountain to heal his injuries.

The injuries on his body were so severe that other students would not be able to stand up at this moment, but Qin Xuan was different. He had a fifth-level peak physical body to support him, so he looked fine on the outside.

Qin Xuan silently practiced the rune catalog and activated the purple gold runes. As the runes rotated, Qin Xuan's injuries quickly recovered.

This scene was also seen by the king on Wenwen Mountain!

"I really don't know what secret Qin Xuan hides. Those seemingly ordinary moves can actually activate the spiritual energy between heaven and earth and exert a healing effect comparable to the Nine Turns Golden Pill!" The king was secretly surprised.

Qin Xuan's secret healing treasure has long been no secret in the eyes of the kings of the Sun Moon Sect, but even these kings don't know that the effect of purple gold runes is far from as simple as healing.

The power of the purple-gold rune that allowed Qin Xuan to survive the thunder catastrophe was unimaginable, but Qin Xuan's current strength was too weak to play the true role of the purple-gold rune.

So these kings also thought that the purple gold runes were just ordinary healing treasures.

This kind of rare treasure can arouse the covetousness of Yaochun, but it will not make the kings put down their dignity and go to fight for it.

After recovering from his injuries, Qin Xuan took the blue-eyed golden eagle to the library.

During this day's continuous battles, Qin Xuan witnessed various changes in the Qi of Transformation. He had a better understanding of the Qi of Transformation, and at the same time he had more doubts.

He originally thought that the transformation of Qi was as simple as out-of-body control, but when he saw Zi Xun standing in the sky, Qin Xuan realized that his understanding of the Qi realm was too shallow!

So he went to the library overnight to look up information on the infuriating energy of transformation.

After burning the incense, Qin Xuan, who was wearing an illusion mask, arrived at the library on a blue-eyed golden eagle.

The first floor of the library is a vast space divided into dozens of areas.

There are tens of thousands of bookshelves here, and the books on the bookshelves can be read by students at their leisure, covering everything from unofficial histories and biographies, martial arts insights, martial arts secrets, and heresy.

There are even some powerful martial arts hidden in a few words. If you can understand them, it will be a chance.

Because of this, many students from ordinary families often hang out in the library.

Qin Xuan walked into the library, looked at the stacks of bookshelves in front of him, and couldn't help but marvel in his heart.

"There are tens of thousands of bookshelves, each with thousands of books. There are probably hundreds of millions of books on one floor of this library!"

These classics were taken by the Sun Moon Sect from various major forces, and they were accumulated from generation to generation to have such a large number.

Qin Xuan walked into the bookshelf and carefully searched for an introduction to the transformation of Qi.

After half an hour, he finally saw hundreds of classics in the upper left corner of a row of bookshelves, all of which were introductions to the transformation of Qi.

"Basic explanation of transformation zhenqi."

Qin Xuan glanced around, then took down a book and read it carefully.

"The three realms of martial arts are divided into the mortal realm, the true qi realm, and the vitality realm. What this book explains is the cultivation method of transforming true qi in the true qi realm."

Qin Xuan's eyes immediately lit up when he saw the first sentence of the introduction. This ancient book was exactly what he needed most at the moment.

"The three realms of martial arts are called the mortal realm, the true energy realm, and the rule realm. They are not made up at will. They are all because of their different cultivation methods. The first three levels of physical training, the true energy of the body, are only dabbled in, and most of them are used in close combat.

Lord, warriors in this realm cannot go to the sky or the sea, cannot control swords with true energy, and cannot borrow the power of heaven and earth. It is the lowest level, so it is called the mortal realm."

"After the fourth level, the acupuncture points all over the body are connected, and the internal and external qi of the human body echo each other. They use their own small celestial beings to mobilize the power of the external great celestial beings. Both their cultivation methods and combat transcend the limitations of the physical body. Many warriors below the third level are limited by their physical bodies.

Martial arts that cannot be practiced can be easily practiced by those who are strong in the True Qi Realm."

…

After two full hours, Qin Xuan finally raised his head and exhaled. This book of only more than thirty pages actually cost him so much time.

You must know that with Qin Xuan's current soul power, he can easily read ten lines at a glance. However, the content in this book is too difficult to understand, so it took him a lot of time to understand it.

"It turns out that the so-called true energy realm is the process of constantly condensing and controlling true energy."

Qin Xuan finally understood why those fourth and fifth level warriors practiced the method of transforming true energy into form, because this was the only way for those who were strong in the true energy realm.

After the fourth level, the acupuncture points of the human body are penetrated, and the small celestial body in the body echoes the large celestial body of heaven and earth spiritual energy. The martial arts master can condense the true energy outside the body and control the true energy to fight. This is the transformation of the true energy into form.

The form of true energy is divided into

There are three realms: the first level is true energy gathering, the second level is true energy condensation array, and the third level is ever-changing.

Of these three realms, the first level is the best to practice. Anyone with a solid foundation in martial arts and strong soul power can achieve it at the fourth level.

The second level of the True Qi Condensation Formation is much more difficult. The True Qi is condensed into an illusory formation, thereby exerting great power. This requires extremely high control of the True Qi. Qin Xuan originally practiced the Infinite Art, and in Dantian

The illusory formation created within is a type of Qi Condensation Formation.

According to the requirements of Wuliang Jue, only those who have reached the fifth level can practice the second level, and those who have reached the sixth level can practice the third level.

If Qin Xuan crosses the third level of cultivation, of course he will fail again and again.

As for the third realm, which is ever-changing and even more difficult than climbing to the sky, reaching this realm, the true energy changes like the heart, gathering and dispersing impermanently. When it is hard, it is comparable to a medium-grade treasure, but when it disperses, it turns into void and is elusive.

This is the ultimate state of true energy.

After reaching this point, the true energy realm has come to an end!

Generally, fourth-level warriors stay at the first level of true energy transformation. The power of true energy transformation at this level is not great. Li Mufeng is on the first level.

However, he has cultivated the extremely rare Thunder Qi. Even at the first level, the power of his Transformation Qi is second only to the top disciples of the major forces, ranking in the top ten of the Thunder Sect. Once he breaks through to the Condensation of Zhen Qi,

The realm of the formation is probably the level of top disciples, and even when faced with figures like Helian Changkong, he can still not fall behind.

Most of the top disciples of the major forces are in the realm of Qi Condensation Formation, such as Helian Changkong and Zixun who have not yet broken through.

As for Dan Yan, who relied on the blue ghost fire, in terms of qualifications, he was still half as good as the top disciples.

The third level of true energy transformation is something that fourth-level warriors cannot understand at all, and even sixth-level warriors can rarely master it.

Zi Xun's third state of true energy transformation did not really reach that level, but it was achieved with the rare treasure Zi Miao Ling. Her true energy had ever-changing characteristics, but it did not have the ultimate cohesion. Otherwise, it would not be the same.

Qin Xuan can be seriously injured with just one strike, but Qin Xuan will not be exhausted until Qin Xuan is exhausted and unable to admit defeat.

Once Zi Miao Ling is lost, Zi Xun's true energy transformation is only at the peak of the second level of condensation formation, so her realm is actually the same as Helian Changkong and others.

"So that's it, this is the Qi of transformation!"
