The Heavenly Demon's method of killing immortals is infinite. Xu Le escaped three hundred kilometers away and finally recovered his injuries. At this time, the lonely demon who was chasing him had long been dumped and disappeared.

After Xu Le Tian Yao Zhuxian Zhuxian Technique broke through, he naturally rarely used the Nine Profound True Method. After all, the Heavenly Demon Zhuxian Technique at the Demon King level is still slightly better than the Nine Profound True Method at the level of the Nine Profound Demonic, but he has never stopped practicing the Nine Profound True Method.

The power of the Nine Profound True Dharma is beyond imagination. The demon level can compete with the demon king level, and there are various mysterious changes. The future will naturally surpass the Heavenly Demon Punishment Method.

Xu Le found a hidden place, gave an order to the black beetle and demon spirit who followed him, and dissipated the demonic energy of Zhuxian and began to practice the Jiuxuan True Method. He had been in the Demon Prison for so long, but he accidentally explored a method to quickly improve the demonic power.

The Xuanjin Demonic Qi is not afraid of the invasion of the demonic energy, but the Thunder and Lightning Demonic Qi and the Sea-swallowing Xuan Whale demonic Qi will be eroded by the demonic energy. Xu tried several times to use the Thunder and Lightning Demonic Qi and the Sea-swallowing Xuan Whale demonic Qi. Afterwards, the demonic energy invaded the body was refined and then turned into the Thunder and Lightning Demonic Qi and the Sea-swallowing Xuan Whale demonic Qi. It is still extremely pure and has no magic intention. After this, the demonic power will be greatly improved.

The monsters and human practitioners who were eroded by the demonic energy began to improve their cultivation speed, which made any peerless genius ashamed. If it weren't for the shortcomings of reversal and the major changes in temperament, the whole world would have been practicing demonic energy.

Xu La's Xuanjin Demonic Qi can purify the Demonic Qi, which has opened a road to heaven for him, allowing him to increase his demonic power by hundreds of points in just a few days. This is because he often encounters battles, otherwise the speed of his cultivation level will be improved more than that.

Xu Le turned all the demonic aura in his body into the sea-swallowing black whale demonic aura. The surging demonic aura turned into a vast ocean. The aura of the Demon Prison was almost like a thirsty horse galloping in the spring. The crows pounced on the moon, causing Xu Le's demonic aura to quickly turn into a demonic aura. The blue demonic aura was like ink, turning layer by layer into pitch black.

Although Xu Le took the risk of using this trick, he did not dare to let the demonic energy invade too much. He didn't know if he would never come back once the demonic energy invades his soul.

The demonic aura of the Sea-Swallowing Black Whale, which he had been ten thousand, was infected by the aura of the Demon Prison, reversed the Nine Profound True Method and turned the demonic aura of the Sea-Swallowing Black Whale into the mysterious gold demonic aura. Originally, he converted the demonic aura for a moment, but now it was ten times more difficult. The demonic aura infected by the demonic aura had to be purified one by one, which was quite time-consuming.

About six or seven hours passed, Xu Lao's eyes opened slightly. A little joy arose in his heart, and the Xuanjin demonic aura increased a little more. Although he didn't know when the Xuanjin demonic aura would boil, as long as the demonic aura could continue to grow, there would be that moment sooner or later.

After making a change of demonic energy, he activated the Heavenly Demon's Immortal Punishment Method to leaps into the sky and continues to pursue the group of black beetles he had previously been involved in the Demon Prison.

Xu Lifei was tired of flying, so he stopped to practice. After finishing his practice, he continued to set off on the road.

Five or six days passed in a blink of an eye. When I was sensing the black beetle group again, it was only a few hundred kilometers away from me.

He was overjoyed and turned into a cold moonlight, flying at high speed. After about half an hour, he saw a group of black beetles.

These black beetles have undergone many mutations, but they are different from before. Each one is the size of a calf, with strange magic patterns all over the body, and even aura of several heads. They are almost breaking through the demon king level.

Xu Le didn't care about the ordinary black beetles, and summoned the black beetles that had swallowed the light gold skeletons, causing them to spit out the light gold skeletons.

Xu put together this light gold skeleton and carefully studied the general outline of the Jade Ding Heart Method above. Although he had known all the mind methods for a long time, this light gold skeleton itself is the best proof.

From this pair of light gold bones, we can figure out how the original owner practiced, what difficulties were there during practice, how he made progress in practicing the Jade Cauldron General Principle, and whether he had made any mistakes. These are things that cannot be seen from the mental method.

After studying for a long time, Xu finally confirmed something. This light gold skeleton was not left by any creature after death, but a magic weapon that was sacrificed. Although he had some speculations, he finally felt it was ridiculous and did not think deeper. After getting in touch with the real thing, all kinds of signs were speculated, and the answer was naturally about to come out.

"The Jade Tripod Heart Method is completely different from the Jiuxuan True Method. Since the demon said that it was the Jade Tripod Demon Lord who had obtained the Demon Nervous Nervous Nervous Nervous Nervous Nervous Nervous Nervous Nervous Nervous Nervous Nervous Nervous Nervous Nervous Nervous Nervous Nervous Nervous Nervous Nervous Nervous Nervous Nervous Nervous Nervous Nervous Nervous Nervous Nervous Nervous Nervous Nervous Nervous Nervous Nervous Nervous Nervous Nervous Nervous Nervous Nervous Nervous Nervous Nervous Nervous Nervous Nervous Nervous Nervous Nervous Nervous Nervous Nervous Nervous Nervous Nervous Nervous Nervous Nervous Nervous Nervous Nervous Nervous Nervous Nervous Nervous Nervous Nervous Nervous Nervous Nervous Nervous Nervous Nervous Nervous Nervous Nervous Nervous Nervous Nervous Nervous Nervous Nervous Nervous Nervous Nervous Nervous Nervous Nervous Nervous Nervous Nervous Nervous Nervous Nervous Nervous Nervous Nervous Nervous Nervous Nervous Nervous Nervous Nervous Nervous Nervous Nervous Nervous Nervous Nervous Nervous Nervous Nervous Nervous Nervous Nervous N

Xu Le played with the Danjin bone for a long time, closed his eyes and said to himself, "And... the most important point is that I can tell that the Nine Profound True Method does not purify the demonic energy that is invaded by the demonic energy. If the Nine Profound True Method has such superpowers, the ancient demon clan does not need to be afraid of demon cultivators, nor will there be a battle to enforce the gods and the battle to burn demons in the immortal way. Being able to purify the demonic energy and turn it into demonic energy is the wonderful use of the general outline of the Jade Tripod Heart Law. In other words... the Jade Tripod lineage is a human cultivator in the Demon Prison that lives!"

Xu Le opened his eyes, and he was also startled by his inference, but if it weren't for this, why would this light gold skeleton or the other magic weapons shine with spiritual energy?

No one on Earth's cultivators and monsters understand the Jade Cauldron Heart Method, and no one who practices this method will fall into the Demon Prison. This light gold skeleton and several magic weapons must not come from outside.

Thousands of years have passed since the ancient battle of the Gods and the battle of the Immortal Demon Burning Demons. If this light gold skeleton and several magic weapons were things from that time, and had been in the Demon Prison for thousands of years, it would have been eroded and rotten by the demonic energy. How could it have been preserved for thousands of years?

This shows that there is only one possibility, that is, these things come from the Demon Prison. There are cultivators living in the Demon Prison. The General Principle of the Jade Cauldron Heart Method can transform demonic energy into demonic energy, which is enough to allow these human cultivators to not be afraid of demonic energy invasion. Even if they fight with demons and monsters in the Demon Prison, as long as they do not die at that time, they can drive away demonic energy and restore their original appearance afterwards.

When Xu Le couldn't help feeling aroused when he thought of the human cultivator in the Demon Prison, he couldn't help but feel aroused. He didn't know how to leave the Demon Prison, and maybe he would never leave. It would be fine if he lived alone in the Demon Prison in a short time. If he endured his hardship for several years, decades, or even hundreds of years, he would probably not become a demon and become a madman. If there were other human cultivators, it would be like encountering an oasis in the desert and finding a paradise in the famine era.
