Xu fell to the ground, all the strength of his body seemed to disappear, and the battle was won, and he didn't understand what was going on, but he felt very tired.

The surprise on Sun Bofang's face had reached the point of exaggeration, and he shouted: "You can actually make the demonic qi vibrate? I don't know how many human cultivators and great monsters want to have their own demonic qi ripples, but not everyone has this opportunity, and you can actually do it in such a short time, which really surprises me." ”

Xu Fenjin had the last bit of strength, raised a middle finger, and scolded with difficulty: "Fake!"

Sun Bofang chuckled and said, "The vast majority of human cultivators and monsters only have one chance of demonic qi shock in their lifetime, and the benefits of cultivating now are more than ten years of cultivation in the future. If you miss this great opportunity, I am afraid that you will not be lucky for the second time in your life, and it is simply foolish to fight with me at this time.

Half-convinced, he asked, "What should I do?"

Sun Bofang laughed and said, "You probably haven't heard of the division of the four qi of the 'Spirit Saint Demon'. I won't go into a long story, but I'll give you a brief and concise explanation. In ancient times, it was believed that there were countless kinds of energy obtained from cultivation, but in modern society and with the advancement of science, we have discovered that there is only one kind of 'qi'. Whether it is a human being, a monster, a demon spirit, or a Western hermit, they all have the same kind of energy, but the frequency of 'qi' is very different, and they will have very different attributes. ”

Sun Bofang stopped Xu Li's question and said, "I don't have time for you to understand, just remember that within a certain band, the higher the frequency of the 'qi' of cultivation, the stronger the power. If you are a monster, you don't care about the other three bands, just remember to get as close to 100,000 hertz as possible, but don't exceed this value, once you exceed the demon energy, it will be mixed, and the quality is not as good as the demon energy with a slightly lower frequency. ”

Although Xu was skeptical, he still followed Sun Bofang's instructions to open the Jasper Seven-Star Mantis Demon, and found the interface to detect the ripples of demon qi. The Jasper Seven-Star Mantis Demon detected that his demonic qi ripples were actually only more than 6,000 hertz, which was quite far away from 100,000 hertz, which made the young man feel bad and hurriedly urged the Heavenly Demon Immortal Method.

Xu didn't know how to increase the vibration frequency of the demonic qi, but when he urged the Heavenly Demon Immortal Method, he naturally started the Star Swallowing Method, and this was the first time he urged this Heavenly Demon Immortal Method.

Since I got the "Star Swallowing Style", although I know that this method is the application method of the Heavenly Demon Immortal Method, it must have infinite use, but I have tried to practice it more than 100 times, but I still can't get in. Even Xu himself didn't expect that he had tried to cultivate so many times, and there was hardly any Star Devouring Style that had entered the realm, would actually break through at such a time, and it would be so logical to break through.

This type of Heavenly Demon Immortal Law is extremely domineering, forcibly turning the black light demon qi into a whirlpool, constantly condensing inward, and every time the black light demon qi shrinks by one point, the demon qi shock will be a level stronger.

The frequency of the demon qi ripples detected by the Jasper Seven-Star Mantis Demon then soared all the way, soon breaking through the 10,000 mark, then 20,000, 30,000, and 40,000......

When all the black light demonic qi was swallowed by the star-swallowing demonic qi vortex, it condensed inward to the extreme!

Xu's lower abdomen seemed to give birth to a starry black hole, and the space couldn't stop collapsing inward, devouring his flesh and blood essence endlessly, and even assimilating his body, starting from the five internal organs, gradually spreading to the bones and blood, and the flesh and blood turned into black light inch by inch.

Xu didn't know what this change was about, whether it was good or bad, at this time he had lost control of his demonic energy, and after watching the demonic energy ripples break through 50,000 hertz, he was like a wild horse, jumping in a few consecutive jumps, approaching the 100,000 hertz mark. He didn't know how to deal with it, and he couldn't even call for help from Sun Bofang, the only thing he could do was to keep his brain awake and watch all these changes happen.

The black light demonic aura was great, and the Xuanjin iron wire in the center of the eyebrows also changed.

It moved slightly, wrapping around the skull of Xu's eyebrows, and gradually expanded, soon turning his entire skull into a faint color of gold.

The black light demon qi permeated the whole body, and the musculoskeletal blood and five internal organs were all eroded by the black light demon qi, Xu didn't know that he had now turned into a humanoid black qi, and he no longer had half of the appearance of a human being, if he knew, he would scream. After all, he was only a junior high school boy, and he couldn't withstand this kind of physical and mental double blow at all, but what was terrifying was that although the black light demonic qi was so strong, there was no way to snatch half a step into Xu's head.

I don't know how long it has been, Xu suddenly felt as if he could move again, he tried to reach out and press the ground to stand up, but he didn't expect it to be the "whole person" floating up flickeringly.

Xu was secretly surprised, and said in his heart: "I don't know if I crossed the 100,000 hertz in the end? If I crossed the line, wouldn't it be terrible?"

Xu glanced at the light curtain that was still faithfully detecting the ripples of demonic energy, and when he saw the number "100190", he couldn't help but be disappointed.

At this moment, the whole body exudes a deep black light, but this black light demon qi is different from before, the previous black light demon qi is like smoke, illusory, but now the black light demon qi is full of an inexplicable power, condensed like a substance, fierce and monstrous.

Sun Bofang was really shocked, this kind of thing is hard to come by, only those with profound skills can accumulate enough foundation to trigger this change, but after all, there are still cultivating geniuses who can trigger it in a very short period of time, but the body demonization must meet extremely demanding requirements, and it should never be the realm that can be achieved by this newly awakened monster.

He jumped down from the bamboo tower and stared at Xu Li, thinking about what to do.

The value of the demonic qi ripples made Xu Yu quite frustrated, he raised his hands, and wanted to ask Sun Bofang, but he was shocked to find that a hand suddenly turned into a black light under his gaze, and even the entire arm was vaporized.

Xu glanced at the other hand again, and this hand instantly vaporized.

He looked at his body and watched as his legs, torso, shoulders and back turned into a cloud of black light.

There was only a faint skull of the color of black gold, and the golden flame in the eyes was faintly extinguished, replacing the original pupil.

Xu raised his head to the sky and roared, full of anger and tragedy.
