The demon clan had withdrawn to the cave, and everyone hid behind the boulder at the entrance of the cave, looking out through a gap tremblingly.

I saw that the black feather had turned into a demon, and the billowing black wind and the thick green poisonous mist collided together, and it was difficult to distinguish between the top and the bottom.

"Interesting ......"

Wu Xuanyuan had to transform into a giant python behind him, and the giant python circled away, its huge body composed of poisonous mist, and attacked the black feather with rapid might.

"A little mage with a golden badge dares to challenge me?"

Black Feather doesn't care if he is a Holy Demon Master or not, no matter who he is, whether it is the Thunder Emperor or the Celestial, as long as he hurts his friends, then even if he fights for his life, Black Feather will lead them to hell!

The black wind and the poisonous mist collided together, and after one move, it was difficult to distinguish the winner from the loser, and Wu Xuanyuan immediately used another tragic killing move.

"Undead corpse poison - Wanli Mound!"

Countless undead surged out of the poisonous gas, scythe-wielding scythes and chains, scurrying away in chains, tying everyone they came across, even the people of the Pantheon.

As the scope of the poisonous mist expanded, everyone who fell from the chain formed a grave, and within a thousand feet, the grass and trees withered, and no one survived.

Black Feather flicked her wings and flew high into the air, avoiding the poisonous mist that covered the ground.

"Rampant boy, don't think you can hide!"

Wu Xuanyuan stretched out his poisonous claw and pointed it towards the sky, "Soul Devouring Claw!"

This move, with a strong suction, can even drain the souls of ordinary people.

Hei Yu suddenly felt a powerful force attracting him towards Wu Xuanyuan, and at the same time, the mana in his body was also flowing rapidly, as if he was absorbing mana and essence when he used dark power to form a devouring black hole.

“...... It is rumored that Wu Xuanyuan cultivates evil arts, and it seems that this is the case. This move is similar to my devouring power......" Black Feather thought to himself.

He wrestled and continued to fly into the air, unleashing a few slashes.

"In order to refine this Soul Devouring Claw, I don't know how many mage's souls I absorbed, and I also accepted your soul!"

While the black feather continued to fall, he condensed the strength of his body in front of the staff according to the method taught by Teacher Yun Lan.

"Magic Light Slash!"

With a roar that tore through the air, a black light in the shape of a crescent moon headed towards Wu Xuanyuan.

Although the black light seems to have no thickness, its power is equivalent to that of the powerful dark storm just now, and no matter how hard the defense is, it will be cut off by this move.

A hint of surprise flashed in Wu Xuanyuan's eyes, of course he wouldn't forget that Yun Lan had used the same move to cut off his head!

He quickly leaped back and dodged the slash. The slash landed on the ground, instantly forming a crack that was a hundred feet deep, although the width of the crack was less than an inch.

Black Feather lost control of the Soul Eater Claw, flailing her wings again and soaring backwards into the air, distancing herself from Wu Xuanyuan and circling him in the sky.

"Hmph. Wu Xuanyuan snorted lightly, full of anger, and his eyes were very vicious. "The person who can force me to use all my strength hasn't met —— Hydra for more than ten years!"

As he spoke, the magic staff in Wu Xuanyuan's hand flashed, and the giant python behind him changed again, entrenched in a ball, and then suddenly stretched out nine snake heads, squirming and gradually growing, the snake body became thicker and thicker, and finally raised high into the sky, blocking the light of the sun.

This is the pattern on the Wu family's family crest - the hydra, and it is a symbol of the peak of venom magic.

The swaying snake shadow fell to the ground, creating a terrifying sight. The demon clan people hiding in the cave were too frightened to make a sound.

Hei Yu said leisurely: "It's really powerful, but your strongest thing is poison, as long as you don't inhale your poisonous gas, you won't be able to hurt me......"

"Then it's up to you!"

The nine snake heads opened their bloody mouths at the same time and struck into the air.

Not only was the snake's body transformed by poisonous mist, but the snake's teeth were dripping with highly poisonous venom, and the black feather quickly shuttled between the snake's attacks, but in a moment, his speed could no longer keep up with the speed of the snake's attack, and he could only rely on space magic to teleportation at a high frequency.

The poisonous mist danced at any moment, spreading through the forest, and a large area of surrounding plants had withered and rotted, and the toxins had seeped into the soil.

"Boy, you seem to have forgotten...... I'm known as the strongest in the continent, but I don't just rely on poisonous attacks, although your speed is fast, if I even know where you're moving next, how can you escape?"

Black Feather was shocked when he heard this.

"Oh no, Wu Xuanyuan has the same crystal ball divination technique as Wu Duck, and can predict where I move next! Moreover, his prediction ability must be stronger than Wu Duck, and the moving location of time and space magic will also be divined by him?......

At this moment, the snake body of the hydra suddenly swept towards him, and this blow was obviously not the point. If Hei Yu didn't dodge, he would be poisoned by the hydra, and if he did, Wu Xuanyuan would be able to predict where he would move next, and attack there early, but he still couldn't dodge!

This is why Wu Xuanyuan is called "invincible".

"Is it really impossible to defeat him?......"

As the Hydra's attack approached, an unwilling thought flashed in Black Feather's heart. He gritted his teeth and did not dodge this blow, but was determined to fight Wu Xuanyuan hard.

"Since you will predict whether you dodge or not, and you will eventually be attacked by you, then you can only knock you down head-on......"

The Hydra's fangs bit down his left arm, blood running down his arm, toxin seeping into his body, and a sharp pain that almost made him spasm. But he held back, sweat pouring down his forehead.

In the face of the Hydra's attack, he used his willpower to restrain himself from falling unconscious, and at the same time calculated the plan, smearing the blood dripping from his arm onto the staff.

"Blood Sacrifice - Darkness Erupts!"

The pitch-black trident absorbed the blood and let out a greedy "hiss" sound, as if enjoying the deliciousness, the blood foam wrapped around his body and flew around, mixing with the dark power to form a crimson black shield, and at the same time, it erupted again with great power, and a huge demon transformed from behind the black feather.

"Ah...... If it's you, what else do you have to do! Use them all! Let me see your strength!"

Wu Xuanyuan saw the change in Black Feather, but he was even more excited, and regarded this battle as a game to stimulate Black Feather's potential.

The boiling dark demonic blood temporarily resisted the speed at which the toxin rushed towards the heart. Within the moment the demon was in force, the devil's claws pressed the snake's head to the ground, cutting off five of them in an instant, but the snake's head quickly regenerated.

The demonic power confronted the hydra, and the devil's claws continued to frantically slap the ground, grasping the body of the snake that was attacking him, and slashing it again and again. The earth shook, stones flew away, and smoke and green mist billowed up.
