Start from Panlong and kill through the heavens

With the help of the Divine Palace Jade, Rean began a frantic pursuit of the Flame Demon God. Rean's current strength was definitely comparable to that of a Universe Venerable; all he lacked was a deeper understanding of the fundamental laws of space.

Although he was able to unleash three spatial fundamental laws, he was far from mastering them. The other fire demon god, however, possessed a level of understanding of laws at the cosmic venerable level. Therefore, even though Rean completely overwhelmed his opponent in terms of power, he could not kill him in a short time.

Rean naturally wanted to kill his opponent directly, preferably to gain his understanding of the laws, and also to absorb all the fire demons on his opponent's body, so that his strength could reach a terrifying level among the Venerables.

That's why Rean relentlessly pursued this fire demon.

The chase lasted for three whole days, until Rean finally killed the fire demon at the edge of the abyss, devouring its true spirit and completely merging it into his own body.

Rean clearly felt that his physical strength had reached an extremely high level, probably billions of times stronger than before. Most importantly, he seemed to have a complete understanding of the fundamental laws of space from birth, and he could use the three methods of instant sealing with ease.

At this moment, Rean's strength had definitely reached an extremely high level among the Universe Venerables, conservatively estimated to be at the level of a High-Level Universe Venerable.

As far as he knew, the power of a demon god in its complete form should be comparable to that of a cosmic overlord. There were no more than two hands' worth of demon gods remaining on the entire ancient continent, but these demon gods were forced to abandon their demon god bodies, and even the races that the demon god bodies transformed into were wiped out.

Among the demon gods still existing in the world, the Flame Demon God is one of the more powerful ones, but it is gradually dying out. If Rean hadn't fused with its bloodline power this time, it probably wouldn't have been long before it perished completely.

Rean has now merged with almost all the fire demons in the Abyss Canyon, but his overall strength is far from returning to the peak state of the Flame Demon God, and this strength of a high-level cosmic venerable will not last long.

Rean felt that once he left the Abyss Canyon, the power of the Fire Demon within him would gradually weaken. If he wanted to maintain the state of a High Universe Venerable, he would have to stay in the Abyss Canyon forever.

Of course, there is another method, which is to draw upon the power of the Heavenly Fire in the Abyss Canyon, turning the entire Heavenly Fire Domain into an abyss-like world. In this way, he can continuously obtain the power of the Fire Demon and gradually recover to the peak state of the Demon God.

However, putting aside the fact that doing so would destroy countless humans and other living beings, even the cosmic venerables in the Heavenly Fire Domain could not stand by and watch Rean turn the Heavenly Fire Domain into a world of lava.

In the end, Rean will be severely injured, just like the Flame Demon God before him, leaving only a wisp of his true spirit, and then he will be suppressed in the Abyss World.

Destroying the true spirit of a demon god is extremely difficult. Only Rean, who possesses the bloodline of a demon god, can completely devour the true spirit of a demon god. Otherwise, the only option is to slowly erode it over time.

As for why the true spirit of the demon god was sealed in the depths of the abyss, it is because the space there is extremely chaotic. Even if the demon god were to escape one day, he would not be able to teleport away and would be trapped immediately.

In other places, once the demon god escapes, it will likely disappear without a trace, and may eventually make a comeback.

After Rean killed the Flame Demon, he released the Divine Palace Jade from his inner world.

Looking at Rean in his demonic form, Jingu Jue's face showed both shock and sorrow. She hovered before Rean's enormous head, reaching out to touch his cheek, her voice trembling as she spoke:
"Why, why is this happening?" At this moment, Jingu Jue already knew that the Flame Demon God in front of her was Rean. She thought that Rean was willing to become the Flame Demon God and be suppressed for eternity in order to save her. Therefore, she felt both moved and heartbroken.

Rean's body gradually shrank until it was about the same size as Jingu Jue, but flames still burned on his body, and his appearance remained that of a fire demon god.

He reached out and grasped Jingu Jue's hand, speaking softly:
"It's alright. I will be able to get rid of this demonic body one day. I will definitely come to find you when that time comes. Wait for me."

After saying this, Rean instantly teleported away from the place. Shen Gongjue wanted to chase after him, but found that he had already disappeared without a trace. How could she, with her barely invincible king-level strength, compare to Rean, who was now a high-level universe venerable?

Rean found a perfect excuse to leave Jingu Jue, but he also made Jingu Jue miss him terribly. When he wanted to leave this world, he would come back again, and if Jingu Jue was willing to go with him then, he would take her away from this world.

Rean returned to the Abyss Canyon. Now his strength has reached an extremely high level. Unless all the Universe Venerables of the Skyfire Domain join forces, they cannot do anything to him, so he is safe for the time being.

So he stayed at the bottom of the abyss and began to cultivate in seclusion, mainly focusing on the fundamental laws of space. He had already personally experienced the complete fundamental laws of space and had already mastered many aspects of them. It was only a matter of time before he could comprehend spatial strangulation and spatial confinement.

While Rean was undergoing arduous training, Irina, the Gold-Eating Vine, and the Haotian were also evolving rapidly, and they consumed all the materials that Rean had purchased.

In the thirty-sixth year of Rean's arduous training, his Spatial Strangulation technique broke through to the Great Perfection realm, and thirteen years later, his Spatial Imprisonment technique was also completely perfected.

However, to Rean's dismay, neither Irina, the Gold-Eating Vine, nor even Haotian broke through to immortality. The difficulty they faced in breaking through to immortality was even greater than his own comprehension of the fundamental laws of space.

Of course, no matter how difficult it is, it can't be as difficult as Rean breaking through to immortality. He feels that he doesn't know when he will be able to break through to immortality. At least for now, he is unable to shake his inner world. He feels like an ant facing a giant mountain.

Meanwhile, his inner world continues to grow stronger as his genetic level increases, expanding from a billion kilometers to several billion kilometers.

The larger the inner world is, the stronger the world barrier becomes, and the more difficult it is to break through the world barrier. He needs to create a powerful secret technique to have any chance of breaking through the world barrier.

After Rean fully comprehended the three fundamental laws of space, he no longer remained in the depths of the abyss, but prepared to leave and continue exploring the ancient world.

He hadn't forgotten his purpose for this trip: to acquire a large amount of resources so that Irina and the Gold-Eating Vine could break through to immortality. However, he hadn't expected to comprehend the fundamental laws of space so quickly, which was an unexpected surprise.

Having comprehended the fundamental laws of space, and with nearly 100,000 times the power of a World Lord, Rean finally reached the limit of the King-Sealing level. If his genetic level were to increase several hundred times further, he would be an invincible King-Sealing being. (End of Chapter)
