Chapter 1552

Of course, what really made him decide to use the power of the four spirits to engrave a great formation in his body was actually related to another world.

Another world named—"Canghai"!

Canghai was one of the three worlds of "Mountain, Sea, and Classic" that Su Xuan had explored earlier, corresponding to the "Sea" in it; of course, in terms of the timeline, it was the latest of the three worlds.

These were three martial arts worlds that were inherited in the same line, and in terms of strength, that was about it.

But some of the martial arts in them were quite interesting, with many unique martial arts.

In the "Canghai" world, Su Xuan obtained a unique martial art, named "Black Heaven Book"!

In the late Song and early Yuan dynasties, Feng Hou, a disciple of Liang Xiao of West Kunlun, was angry that his master had gone far to the Central Plains, so he was angry at the people of the Tianji Palace and fought, but was defeated by "Mirror~~Heaven" Hua Jingyuan; however, Jing Tian loved Feng Hou bitterly and showed mercy many times. In order to defeat Jing Tian, Feng Hou invited him to study the "Hidden Meridians" recorded in the medical classics left by Feng Hou's master's wife, Hua Xiaoshuang, and the two lived in seclusion in the wind cave of the East Island and finally created the Black Heaven Book; however, practicing the Black Heaven Book required one slave and one master, Feng Hou was the slave, Jing Tian was the master, Feng Hou could not defeat Jing Tian after all, and Jing Tian also died of bitterness because of his unrequited love.

Although the two had already died, the Black Heaven Book was still passed down.

Originally, a martial arts book from a martial arts world was not enough to make Su Xuan care so much.

But it couldn't be helped that some of the concepts in the Black Heaven Book were extremely interesting, especially the part about "Hidden Meridians"; Hidden Meridians were accidentally discovered by Liang Xiao's wife, Hua Xiaoshuang; the human body has subtle meridian flows outside of ordinary meridians; after exploring all the way, thirty-one meridian flows were discovered one after another; because their meridian nature was completely different from ordinary meridians, they were called Hidden Meridians. After hearing about it, Liang Xiao thought that these thirty-one Hidden Meridians matched the number of heaven, so he named them after the Three Enclosures and Twenty-Eight Mansions.

After Su Xuan obtained the Black Heaven Book in the "Canghai" world, he also discerned these secrets, and then he kept these thirty-one Hidden Meridians in his heart.

One must know that although practitioners of immortality swallow the creation of heaven and earth, nourish the primordial spirit, and open the ancestral aperture between the eyebrows, the operation of magic power still needs to pass through the meridians in the body.

People in the "Canghai" world practice the Black Heaven Book by connecting the thirty-one Hidden Meridians one by one, and then opening the Sea of Tribulation.

Su Xuan did not intend to practice in this way.

He prepared to set up a great formation with these thirty-one Hidden Meridians according to the pattern of the Three Enclosures, Four Symbols, and Twenty-Eight Mansions.

Under Su Xuan's guidance, the power of the four spirits went to many Hidden Meridians respectively.

Although the Four Symbols and the four spirits were completely different, the power of the four spirits could barely be used.

Dragon Essence power corresponds to the Azure Dragon in the East.

Mysterious tortoise power, Su Xuan used to correspond to the Black Tortoise.

Phoenix corresponds to the Vermilion Bird.

Qilin corresponds to the White Tiger.

The four forces flowed into twenty-eight Hidden Meridians respectively, and in an instant, a formation of Four Symbols condensed in Su Xuan's body.

And among the twenty-eight Hidden Meridians, the three that were regarded as the Three Enclosures, Su Xuan did not let go either.

The power of the Yin Spirit flowed into the lower enclosure, the Heavenly Market Enclosure, the power of the Yang Spirit flowed into the upper enclosure, the Supreme Subtle Enclosure, and then the primordial spirit of Yin and Yang combined entered the central Purple Forbidden Enclosure.

The power of the four spirits, surrounding the Three Enclosures, in an instant, a magnificent great formation took shape in Su Xuan's body.

Afterward, Su Xuan's figure suddenly left the God of War Hall and arrived in the real world.

In the real world, it was already night at this moment.

Su Xuan glanced at the distant Xianyang City.

His figure flashed, and he left Lishan instantly; not long after, Su Xuan arrived at a wilderness.

Here, for a hundred miles around, there were few people.

If it were in the past, Su Xuan would obviously not do such a thing, but it couldn't be helped that the movement he wanted to make next was a little big, so in order to minimize the movement as much as possible, he had to come to a place with few people.

The night sky was high, and the stars were dotted.

Su Xuan sat cross-legged in mid-air, and the next moment, the formation in his body started.

Thirty-one Hidden Meridians emitted energy fluctuations at the same time.

The power of the stars in the sky immediately gathered, and the starlight fell on Su Xuan's body.

This was a technique of gathering spirits that he learned in the God of War Hall.

In the Qin world, the vitality of heaven and earth is limited, and it is difficult to become an immortal with the vitality of heaven and earth, but this does not mean that there is no way at all; in the sky, there is actually another vast and endless power, which is the power of the stars.

In the past, Su Xuan had no way to attract the power of the stars.

But after contemplating the great formation of the God of War Hall, he had a definite way.

The power of the stars like the ocean constantly surged toward Su Xuan; even if Su Xuan tried his best to find a sparsely populated place to break through, such movement was really too big; soon, in all parts of the world, many strong people felt it one after another, and star observers discovered that the stars in the sky suddenly dimmed.

A feeling of wind and rain coming was born.

Su Xuan did not care about the changes he caused; after the power of the stars entered his body, the power of the Dragon Essence, Phoenix Blood, mysterious tortoise power, and Qilin blood in his body were all melting.

Especially the power of the Dragon Essence, after melting, it turned into an incomparably huge force that penetrated his entire body.

The Immortal Spirit Law that had initially taken shape, under Su Xuan's manipulation, immediately drew these forces, and then, constantly grew stronger.

The Immortal Spirit Law was born!

With its birth, a rich immortal spirit energy was born on Su Xuan's body.

Shedding Mortality, Primordial Spirit, Mysterious Penetration, Immortal Spirit, Sacred!

Five great realms, today, Su Xuan finally entered the fourth realm, "Immortal Spirit"!
