Although the snake head will soon spawn again, after all, the snake head is made of Wu Xuanyuan's mana, and each time it is cut off, it will cause a loss of his mana.

But Wu Xuanyuan's own mana was too powerful, so he couldn't see the change at all, and every time the snake head was interrupted, it would instantly return to its original state.

"Whirlwind Slash!"

At the same time as the strength of the black feather increased, he immediately swung his staff and launched a slash at Wu Xuanyuan, and a black whirlwind was wrapped in countless blades, and it went towards Wu Xuanyuan furiously.

This blow was a fusion of the Dark Storm and the Magic Light Slash, even if Wu Xuanyuan could predict it, but he couldn't dodge the countless slashes contained in the storm, and a black blade scratched his skin, angering him who was watching the play.

"What? You can hurt me?"

He didn't seem to be injured in a long time, and although it was only a small abrasion, it was too unexpected for him.

"There are two hits, see how long you can last!"

He withdrew a large snake in front of him, and the snake snaked its body, dispersing Black Feather's attack, opening its huge mouth to bite Black Feather, while another large snake had quietly circled behind Black Feather and slammed into his back.

Black Feather felt a gust of wind behind him, and knew that it was not good, but the snake head in front of him was already in front of him, and while he turned his body, the demon behind him also turned his body, attacking the two snake heads with his arms one after the other.

As soon as he turned around, two other snakes quickly attacked him from one left and one from the right, and the speed was faster than before.

"Not good!"

There was no time to react, Hei Yu was about to use the space-time spell to dodge, but his body was numb from the previous poisoning, and his reaction was a step slower than usual.

While flipping his body in the air, avoiding the attack of the poisonous snake's fangs on the vital point, he wanted to spread his wings and escape, but he was hit by the snake heads on both sides and could only spin in the air, and at the same time, the snake body turned into two poisonous mist and passed through his body.

Compared to ordinary poisonous mist attacks, the two snake bodies passed through from head to tail, and the toxins were absorbed by the black feather a hundred times, if it weren't for the protection of the blood shield around his body, his skin would probably have rotted.

The demon behind him suddenly vanished, and his strength and consciousness gradually lost, and he fell to the ground again. Wu Xuanyuan would not stop there, he shot ruthlessly, seized the opportunity, and immediately launched a poisonous pool in the direction where he landed.

"Gas pool!"

“...... It's this trick!!"

Black Feather was horrified.

In the Dharma Fighting Competition, he had seen the witch owl use this trick. The gas pool is made from a thousand toxins plus corpse poison. And corpse poison is the most ruthless of Wu Xuanyuan's toxins, which can instantly turn the person in contact into pus.

Hei Yu looked at the wide poisonous pool unfolding under him, thinking of a way in his heart, but he no longer had the strength to dodge and fell vertically. The undead greeted him with twig-like hands.

"That's it, Son of the Devil! You have dark powers, but you're still too weak!"

Wu Xuanyuan laughed wildly.

“...... If you fall into the poison pool, you will definitely die, so you might as well fight with him. If you open another seal, the power of the demon will increase, and it will not be controlled by the toxin. Moreover, now that there is no one else around, Ling Xiaotear and the companions of the demon clan are also safe, and if they go viral, they will not accidentally hurt others......"

He looked at the ground, and the demons were already hiding in the cave entrance, and in the open space in front of him, there were only the corpses of the Pantheon soldiers.

The moment his body touched the poison pool, Black Feather closed his eyes lightly, and he gave all his hope in a desperate gamble.

"The Fourth Seal - Open!"

A dark whirlwind rose into the air again, shattering the undead who had grabbed Black Feather's body and was dragging him down the poison pool.

The demon conjured out again, stepped over the poison pool with both feet, caught the black feather with one hand, and pressed the hydra behind Wu Xuanyuan with the other clutch.

Under the fourth seal, the rushing dark blood caused Black Feather's skin to crack, oozing blood, and the internal organs were also under tremendous pressure, coupled with the erosion of the toxin on the body, in the state of blood sacrifice, the more blood he lost, the stronger his strength, as the so-called more frustration and braver.

"There is still ...... room to spare," Wu Xuanyuan pursed his lips.

Before he finished speaking, he saw Black Feather pounce towards Wu Xuanyuan like a monster that had lost his mind, and at this time he had already flashed in front of him with a magic staff, and the tip of the trident pointed at the center of his eyebrows.

"So fast?!"

Wu Xuanyuan's back was cold, and he hurriedly dodged sideways to the side, and the black feather passed by him, his eyes flashing with cold killing intent.

In the move just now, Hei Yu did not use the technique of time and space, but the simple speed, which was already so fast that Wu Xuanyuan was surprised.

"It turns out that your power is not all...... There's room for upside, son of the devil, you're surprising me more and more!"

Wu Xuanyuan said. But soon, his smile froze.

The transformed demon moved behind Black Feather again, Black Feather roared angrily from mid-air, the demon opened its huge mouth, and black turbid gas gushed with the roar, covering the ground and covering Wu Xuanyuan's poisonous mist.

He flapped his wings again and swooped down, the blood droplets on his body splashed backwards, the crystal ball behind Wu Xuanyuan flashed red, and he was just about to dodge, when suddenly his movements were seen through by the demonic eye of Black Feather, and the demon's hands behind him immediately fell, holding Wu Xuanyuan's arms and pressing him firmly to the ground.

Under the fourth seal, the Demon Eye's speed bonus not only increased by a hundredfold, but even surpassed Wu Xuanyuan's divination speed, even if Wu Xuanyuan's crystal ball could show everything, he didn't have time to use the power of the crystal ball.

And the Demon Eye, with the addition of a short-term foresight ability, can see through Wu Xuanyuan's actions in advance.

The big snake tightly wrapped around the demon's arm, and Hei Yu's arm also felt a pressure to be strangled, but he didn't let go at all, and pressed Wu Xuanyuan to the ground tightly.

At the same time, a black flash lit up at the tip of the trident, and the crescent-shaped "Magic Light Slash" headed towards Wu Xuanyuan.

"Don't deceive people too much......"

Wu Xuanyuan frowned, the corners of his mouth twitched, and his face sank. The demon's palm suddenly emptied, and he only felt that Wu Xuanyuan's two sleeves had lost his arm, and there was nothingness.

Hei Yu was taken aback, it was worthy of the strength of the Holy Demon Master, and it was not so easy to catch the flaw.

"Gas pool!"

Wu Xuanyuan unfolded the poison pool on the ground behind him, and his whole body fell into it, gradually sinking, and the magic light slash disappeared on the water surface of the poison pool.

The blow missed, and Black Feather jumped back, keeping a distance from the poison pool, observing Wu Xuanyuan's next move.

At the same time, he was also wheezing violently, and every violent beating of his heart caused severe pain all over his body. The venom had already drenched his whole body in blood, but fortunately he was still conscious.
