At the beginning of the Black Evil Ghost Territory in the Black Evil Plains, Xing Feng captured a Black Evil Ghost Puppet through mind control, and then combined it with the Sky Eater for the first time, and previously combined the Sky Eater with the creature in the form of an octopus and a creature in the form of a beetle, so far, the Sky Eater has been combined three times.

At present, Xing Feng's puppet combination skill has reached level 8, plus the increased skill level effect of the Blood Demon Jewelry and the Four Elephant Pei, the skill level has reached 8+5 at this time, that is, the Sky Devouring Beast can be combined up to 13 times.

Although the process of combining the puppets has to take some risks, and it is possible that the combat power of the puppets combined will be greatly enhanced, and of course, it may also be greatly weakened, but Xing Feng has found some clues from the process of combining the Sky Swallowing Beasts, that is, the creatures that also have the power of chaos in the combination will inevitably enhance the strength of the Sky Swallowing Beasts, and it will never be weakened, which also makes Xing Feng have the idea of taking this opportunity to complete the combination of the Sky Swallowing Beasts 13 times.

Next, Xing Feng took the Sky Swallower Beast to swim for a long time in this underground mysterious space full of chaotic aura, but whenever he encountered a creature like the Sky Swallowing Beast with the power of chaos in its body, he captured it and turned it into a puppet, and then combined it with the Sky Swallowing Beast.

Unconsciously, three days of time passed in a snap of a finger, these three days, the impact on the Sky Swallowing Beast was undoubtedly great, during which Xing Feng controlled nine creatures similar to the Sky Swallowing Beast, and without exception combined them with the Sky Swallowing Beast, and at this time, the number of combinations of the Sky Swallowing Beast had reached 12 times, and there was one last chance to combine, if it was combined again, then if you wanted to continue to combine, you could only go through the combination again when the skill level was improved again.

The current form of the Sky Swallowing Beast had undergone great changes, and if Xing Feng had encountered such a form of the Sky Swallowing Beast when he entered this space, then it would be impossible for him to recognize that this was the puppet he had been.

At this time, the volume of the Sky Swallowing Beast was as high as a four-story building, white meters long, and the head in the form of a shark was extremely hideous, with a sharp single horn more than twenty meters long, and its huge mouth was full of hideous teeth, giving people an extremely fierce and cruel feeling.

Two long, dancing whiskers sprouted from their nostrils, tens of meters in length, like a steel whip, with countless fine spikes on them, and sometimes coiling around a slight arc.

Protruding bone spurs appeared on the tiger's body, eagle claws, and back spine, which looked extremely hideous.

It can be said that at this time, the form of the Sky Swallowing Beast has undergone unimaginable changes, and in terms of strength, although the cultivation is only five heavens, in terms of combat power, it is more than ten times stronger than when it was not combined before, you must know that the cultivation of the Sky Swallowing Beast has reached the eighth heaven!

If you put it in a way of comparison, at this time, the Heaven Devouring Beast that has cultivated to only five heavens can already fight with the aborigines of the secret realm!

With such a talent, Xing Feng was envious, and he planned to start immediately, and work hard to cultivate the Sky Devouring Beast, so that its cultivation could be greatly improved!

Xing Feng took advantage of the rest time to take out two fog spirit beads from his backpack, these fog spirit beads Xing Feng was not willing to increase his cultivation through them, for him who is now cultivating in the divine domain, the effect of the fog spirit beads is negligible, originally planned to give all the fog spirit beads condensed by the haze demon to Ba Qi to restore its cultivation, but now that he has a talented Sky Swallowing Beast, Xing Feng naturally has to take care of it!

After swallowing the two Mist Spirit Beads, after another two days, the strength of the Heaven Devouring Beast was finally improved again, and it leaped from the Fifth Heaven to the Sixth Heaven Cultivation.

Xing Feng knew very well that the Mist Spirit Bead could not be taken continuously, although it could make the cultivation speed increase rapidly for a while, it would also give birth to the immune effect of the Mist Spirit Bead, and if he took it again in the future, the effect would be greatly weakened, so he could only divide the time in an orderly manner to let the Sky Devouring Beast take it.

In the past few days, Xing Feng has explored almost the entire underground space, but he still hasn't found any trace of the Chaos Demon, seeing that the chaotic aura in front of him not far away is extremely strong, and even Xing Feng feels extremely uncomfortable, in such an environment, let Xing Feng think about it with his knees, he can judge the extraordinaryness here, there is a great possibility, the legendary Chaos Demon is in front of the position full of strong chaotic aura!

Ba Qi and the Sky Devouring Beast followed closely behind Xing Feng, and walked towards the range where the chaotic aura was raging, the colorful mottled energy in front of them was constantly changing, evolving into various auras in long strips, or accumulations, or in the form of mist formations, Xing Feng used the domain power to penetrate this chaotic aura and see what was in it, but the result made him very disappointed, the domain power had no effect at all, with the initial cultivation of the Divine Domain, he could compete with the final domain power of the Divine Domain, and he couldn't use the domain power to view everything not far in front of him, This made Xing Feng even more cautious.

As he moved forward, Xing Feng quickly stepped into the range filled with chaotic aura, which made Xing Feng feel that his soul couldn't help but tremble, it was a very uncomfortable feeling, as if his limbs, flesh and blood, were being pulled by an extremely strong force, as if he was about to tear his body into nothingness.

Xing Feng's face was gloomy, and he suddenly stretched out his hand, and through his spiritual power, he conjured a huge spiritual palm, and slammed it towards the void, and the rich chaotic aura was actually scattered by him like a lot of smoke driven away.

Xing Feng's eyes suddenly froze, and he saw a mass of things, to be exact, a mass of spatial ripples, translucent, looking at all objects behind him through this ripple, they all looked very distorted.

"Could it be that this guy is the Chaos Demon?"

Xing Feng said a word, and Baqi's voice immediately came into Xing Feng's mind: "Master, this is the Chaos Demon, formless and incorporeal, it looks like it's just a distorted form of space, but this guy is extremely terrifying, he can devour everything, it's everything!" ”

"Devouring everything?" Xing Feng felt very curious, and suddenly stretched out his finger, which was his self-created skill 'Thunder Finger'.

The bright light flew over, but just as he was about to hit the distorted position, the distorted space, that is, the Chaos Demon's body, expanded violently, like a huge mirror, suddenly enveloping Xing Feng's thunderous finger, and then the surrounding space became quiet again.

Xing Feng couldn't help but gasp, he knew better than anyone else the power of the thunder finger, it was a powerful energy system that could resist the heavenly punishment, but at this time, he was swallowed up by this so-called chaos demon so lightly, how could he blame Xing Feng for being so surprised.

Xing Feng, who didn't believe in evil, released a crossbow puppet this time and rushed forward to test it, but the result was still similar to before, the chaos demon was wrapped like a sack again, and as for the crossbow puppet with extremely strong single strength, it also disappeared without a trace, and not even a little residue was left.

"This ......" Xing Feng was speechless for a moment, this kind of power system is too weird, it can be said that it is an energy system and attack method that Xing Feng has never seen before, which makes Xing Feng's previous idea of controlling this so-called chaos demon as a puppet through spiritual power is also dispelled, just kidding, if you devour your own spiritual power, you will be hurt by a strong backlash, not to mention that it is very troublesome to recover the lost spiritual power.

The curious Xing Feng finally decided to take a risk and not experience this power system in person, if you just guess, it would be a headache......
