And that's not all.

The evil aura of the Ghost Head Knife was also violently released, as if it was echoing with the thunderous power of the black orb.

Time.

Chen Qingyang only felt that the aura of evil qi and thunder was all around his body.

"What the hell is going on?"

Sensing the violent tremor of the ghost head knife in his palm, Chen Qingyang was secretly surprised.

He really couldn't understand what was happening in front of him.

Why did his own ghost head knife suddenly seem to have spirituality, and reacted extremely strongly to the appearance of the black orb!

And just when Chen Qingyang couldn't think of a reason to come.

Something even weirder has happened!

I saw that the black orb, with a raging arc of electricity, automatically detached from the crystal pedestal, and slowly flew towards the ghost head knife.

It seems to welcome the arrival of the black balls.

The evil aura of the Ghost Head Knife escaped incomparably turbulently, filling the entire treasure house in an instant.

This caused Chen Qingyang to feel suffocated.

The aura was shrouded, and the Ghost Head Knife soon bloomed with a strange black light.

It is also under the arch of black light.

The black balls, little by little, are approaching the Devil's Head Knife.

Until the end.

It fell into the hilt of the Devil's Head Knife, where the eerie face was!

Snort, sneer!

With the sound of arc rushing, the black bead directly fused with the ghost face of the ghost head knife.

It feels as if the two are born to be one!

The moment when the fusion is complete.

Chen Qingyang only felt the power of the Ghost Head Knife, and directly rose to a level!

The whole body is full of evil, and there are thunders around you!

"Do you mean ......?"

His eyes flickered, and Chen Qingyang's heart jumped violently: "My ghost head knife, has it advanced?

Be aware of this possibility.

Chen Qingyang's heart can't tell how happy it is!

Because he knew that with a medium-grade treasure weapon in his hand, his hope of killing that one-horned rhinoceros would be greatly enhanced!

"That one-horned rhinoceros, if I knew that the two most important treasures in his treasure vault had fallen into my hands, I was afraid that he would go crazy on the spot, right?"

As a matter of muttering secretly, Chen Qingyang re-shouldered the Ghost Head Knife and prepared to leave the treasure house refreshed.

He was undoubtedly thinking that before the one-horned rhinoceros returned, he would go out and kill more monsters and accumulate some more refining weights.

Only in this way can he be more sure that he can compete with that one-horned rhino!

It was just when Chen Qingyang was just about to leave.

A loud shout suddenly resounded throughout the cave:

"Who is it!dare to come to our Qinghuang Cave to spread wilderness!!

The shout was heard.

Chen Qingyang's eyes sank suddenly.

Because he could fully sense that a series of heavy footsteps were constantly approaching him.

"Seemingly, it's the one-horned rhinoceros?"

Feeling the breath that was constantly sweeping in, Chen Qingyang secretly thought: "I'm afraid, it's one of the top ten commander-level demons in the Qinghuang Mountain Range who went out to hunt down the four young swords of the flying sword, right?"

No wonder Chen Qingyang has such a judgment.

Because, he could obviously sense that the aura of this upcoming monster was better than the Sand Devouring Ant Queen in the Sand Devouring Valley!

And when he thought that he was about to encounter a powerful commander-level demon.

Chen Qingyang's spirit was instantly lifted, and his eyes were full of war intent!

He really wanted to see how much combat power he could burst out after cultivating the fourth level of the Heavy Mountain Technique, and holding a Ghost Head Knife at the level of a medium-grade treasure weapon!

And so.

Chen Qingyang stood proudly in place and quietly began to wait for the arrival of the commander-level demon.

Knock! Knock!

............

The sound of footsteps like a vibrating drum became louder and louder in Chen Qingyang's ears.

Not much.

Chen Qingyang saw that a wild bull demon was full of ferocity and killed in the treasure house.

This bull demon is extremely tall, more than two people tall.

He is holding a giant axe, shirtless, his eyes are like green fire, and his image is very similar to the Bull Demon King that Chen Qingyang saw on TV in his previous life.

"This is one of the ten demon kings of the Qinghuang Mountain Range, the Blue Fire Giant Bull?"

Recalling the introduction in the guide, Chen Qingyang quickly recognized the identity of this wild bull demon.

Meantime.

He could probably guess why the green fire bull had returned early.

The reason is simple.

Although the Blue Fire Giant Bull looked tall, its muscles were as solid as green vines wrapped around its body, and its strength was more than three thousand catties.

The frontal combat power is extremely amazing, and it is definitely in the forefront of the top ten demon kings.

But this big guy is very peculiar and not good at running!

In terms of speed, not to mention that it is as slow as an old cow, it is definitely much weaker than the average commander-level demon.

So you can imagine it.

The Blue Fire Giant Bull went to participate in the pursuit of the four young swords, but he was basically left behind by everyone.

It's all the way to running blindly, chasing blindly!

In a fit of anger, the Green Fire Giant Bull no longer participated in the chase and returned to the lair in advance, which was a normal thing.

"Huh, there's only one human kid?"

Glancing at Chen Qingyang casually, the Green Fire Giant Bull showed absolute disdain.

It seems that the number of people is still disliked is too small, only Chen Qingyang is the only one, which is not enough for him to stuff his teeth!

And then.

With a cold snort, the Qinghuo Giant Bull didn't talk to Chen Qingyang, and directly took a fierce step and killed with an axe.

Judging by the situation, he is preparing to sprinkle all the anger accumulated this day on Chen Qingyang!

Later, Chen Qingyang will be chopped alive with a giant axe!

And in the face of the fierce offensive of the Blue Fire Giant.

Chen Qingyang's expression did not change, he just held the handle of the ghost head knife behind his back with his right hand.

Just one breath has passed.

The Qinghuo Giant Bull approached Chen Qingyang with a hideous face.

The giant axe in his hand has been lifted!

ready to slash at Chen Qingyang's waist at any time, and directly hack Chen Qingyang to death with his waist.

This is also the favorite way of killing the Green Fire Giant Bull.

"Town!"

At this moment, Chen Qingyang snorted lightly and urged the Heavy Mountain Technique.

The Fourth Heavy Mountain Technique!

More than six hundred pounds of weight, instantly added to the green fire giant bull!

"What's going on!"

The Blue Fire Giant Bull suddenly stumbled, only to feel a big black bear pounce on him, which suddenly crushed him to the point of pain in his bones.

And Chen Qingyang also found this opportunity, and coldly pulled out his knife and cut out.

As soon as the ghost head knife came out, it was like a meteor falling from the sky.

Wrapped in Chen Qingyang's three thousand catties of huge force, he slashed at the neck of the Qinghuo Giant Bull.

The evil aura of the sword, accompanied by thunder, also erupted wildly at this time!

attracted the breath of the ghost head knife, and instantly climbed to the extreme!

"Ah——————h

Sensing the terrifying power emanating from the Ghost Head Knife, the Blue Fire Giant Bull's face turned white all of a sudden, and he couldn't help but exclaim.

The next moment.

Scold!!!!!!

Before he had time to react or say any more words, the huge bull head of the Qinghuo Giant Bull was cut down by Chen Qingyang with a knife.

The moment the head and body separated, the eyes of the green fire giant bull widened like green lights.

The expression is full of unwillingness and ...... Shock!

Shocked by Chen Qingyang's arrogance!

He couldn't believe how a sixteen or seventeen-year-old human boy could be so strong.

With one sword, slash him, a commander-level demon!

"Commander-level demons?"

Looking at the bull head rolling to the ground, Chen Qingyang was expressionless, and said lightly: "It seems that it's nothing more than that!"
