"Click!"

The crisp cracking sound resounded in Chu Ling's sea of consciousness, and Chu Ling's body suddenly trembled, and his face instantly turned extremely pale. He felt as if something had been broken in his mind, and then, the spiritual power in the sea of consciousness began to converge towards the central point.

There, the crystal clear spiritual embryo like perfect jade, there were obvious cracks on the surface of the explosion, and the seedling in it was fiercely pressed against the cracks, as if it was about to break through the ground.

"Broken tire!"

Sensing this scene, Chu Ling's heart was shocked, and he knew from the annotations in the Holy Clan's inheritance that the current situation was the key to promotion. That spiritual seedling should break open the embryo and grow out.

In the sea of knowledge, the violent spiritual power seemed to turn into a storm in the sky, roaring. Then, like a tidal wave bursting on a, it rushed towards the spiritual embryo.

And with the influx of the last trace of spiritual power, the feeling of sharp pain that made Chu Ling almost go crazy finally disappeared. And that spiritual seedling also broke out of the fetus, swaying gently.

Chu Ling's eyes suddenly opened at this moment, and a whistling sound came out of his throat uncontrollably. And at the same time as this howling sound resounded, an extremely strong spiritual force was also suddenly swept out of his sea of consciousness!

"Boom!"

This cave opened up by Chu Ling himself trembled violently at this moment, and an invisible fluctuation spread out in all directions like a storm centered on Chu Ling. On the ground, cracks exploded, and a layer of gravel dust on the surface spread out in a circle, and finally hit the surrounding mountain walls heavily. The whole cave trembled again.

"Hoo ....."

A rapid gasp came from Chu Ling's mouth, his hands supported the ground, his chest rose and fell violently, and on his pale face, there were lines of sweat dripping to the ground.

The kind of severe pain caused by the breakthrough of the spiritual realm before made him still have palpitations at this time. However, in the pupils of his eyes, there was a strong color of ecstasy.

"This spiritual realm breakthrough, how can it hurt so much?" Chu Ling gritted his teeth, and immediately looked around, his eyes suddenly became shocked. "But this kind of power is really terrifying enough. ”

It's just that the unconscious mental fluctuations during the breakthrough cause this kind of destructive power, so if it is deliberately manipulated and used to kill the pupil of the sky?

Chu Ling sat cross-legged again, he could feel that the spiritual power in his sea of consciousness was undoubtedly more than ten times stronger than before!

Looking inward, Chu Ling saw at a glance that in his sea of consciousness, a beautiful little seedling like a crystal was suspended in mid-air, swaying slightly. And among the seedlings, there was a majestic spiritual power that even Chu Ling himself was a little frightened about.

And just when Chu Ling was trembling at the spiritual seedling in his sea of knowledge, he suddenly found that on the light curtain, the location of the Holy Clan's inheritance suddenly appeared.

"What's that?"

Chu Ling's heart moved, and he hurriedly looked over.

"Saint Yuan Heart Codex!"

The first thing that catches the eye is the four ancient seal characters that are permeated with ancient fluctuations. And as Chu Ling continued to watch, the look on his face also froze little by little.

This so-called Holy Yuan Heart Code is a mental method that specializes in cultivating spiritual power! And its level is completely equivalent to the Emperor Demon Heavenly Law! Moreover, the source of this Holy Yuan Heart Code is the Xuanxin Heavenly Maiden clan in the human race!

And the status of the Xuanxin Heavenly Maiden clan in the human race is equivalent to the status of the emperor demon clan in the demon gods of all directions. The Holy Yuan Heart Code is the supreme holy book that only the core clansmen of the Xuanxin Heavenly Maiden clan can cultivate!

The Holy Yuan Heart Code is a holy book for the cultivation of spiritual power.

Chu Ling has two bloodlines, the Emperor Demon bloodline specializes in martial arts, while the spiritual holy veins of the Xuanxin Heavenly Maiden clan are the same as spiritual power.

The Emperor Demon Heavenly Law is the supreme heart method for cultivating martial arts, and it can reach the ten levels of martial arts. But as for how to cultivate spiritual power, Chu Ling didn't have any method.

Chu Ling didn't expect that after his spiritual realm broke through the third grade, in the inheritance of the Holy Clan, there would be a Saint Yuan Heart Dictionary that specialized in spiritual cultivation!

"What's going on?" Chu Ling was shocked in his heart at the same time, but he was also quite puzzled, he couldn't figure out how this Saint Yuan Heart Book could only appear at this time.

In fact, Chu Ling didn't know that his parents knew that he had the bloodline of the Demon Saint and the two clans, but they were not sure whether he could be a fellow demon saint practitioner in the end. And the two bloodlines, the emperor demon bloodline dominates. If Chu Ling couldn't cultivate the dual path together, he could only abandon the spiritual holy vein and specialize in the demon path.

And the Holy Yuan Heart Code is the same as the Emperor Demon Heavenly Law, if there is no spiritual holy vein passed down by the Xuanxin Heavenly Maiden clan in the body, it will not be able to cultivate.

Therefore, Chu Ling's mother, the holy daughter of the Xuanxin Heavenly Maiden clan, hid this Holy Yuan Heart Codex, and only when Chu Ling's spiritual realm broke through to the third grade and reached the realm of breaking the fetus, and there was still the spiritual holy vein of the Xuanxin Heavenly Maiden clan on her body, it would be revealed.

The Holy Vein Seal, after the Emperor Demon Bloodline Seal, can only be unlocked by breaking the Emperor Demon Bloodline Seal first, and then the corresponding Holy Vein Seal can be unlocked.

Normally, the improvement of the bloodline lags behind the cultivation of the martial arts. In other words, Chu Ling would first break through to the Danhai Realm, and then he would completely unlock and activate the second bloodline seal. And at that time, there must have been results, either a fellow demon saint, or a demon dao.

However, those two powerhouses did their best, but they never thought that Chu Ling would break the second bloodline seal in advance due to various coincidences. At the same time, his spiritual realm surpassed martial arts cultivation and broke through to the third rank first.

As a result, the current Chu Ling, when he was not sure whether he could cultivate the Demon Saint Dual Dao with him, obtained the Saint Yuan Heart Code in advance. And what Chu Ling didn't know was that once he cultivated the Saint Yuan Heart Classic now, then he would no longer have a choice, and there was only one way left, which was the Demon Saint Initiate!

Because if he fails, the seal in his body will forcibly deprive him of his spiritual vein. And if he loses the spiritual holy vein, but he cultivates the Holy Yuan Heart Codex, he will be counterattacked because of this, and his soul will be scattered!

However, Chu Ling, who didn't know about this powerful relationship, how could he abandon it after obtaining the supreme holy scripture of the Holy Yuan Heart Codex?

- Brothers, if you are in a hurry, you can go and read Hongming's old book, Zhantian Demon God, which is also wonderful.
