Let you be a good grandson, you raise a group of banshees?

Lu Yuan's Xuanyuan Sword burst out with a strong sword energy, heading straight for the leader of the Black Demon Sect.

The sword energy cut through the air like thunder, and the strong spiritual power fluctuations shook the surroundings, instantly tearing apart the evil energy in the palace.

The leader of the Black Demon Sect smiled slightly, with a cold light flashing in his eyes.

He gently waved the black scepter in his hand, and the air around him seemed to be bound by an invisible force. The sword energy suddenly stagnated a few steps away from him and dissipated in an instant.

"Lu Yuan, do you think the power of the Xuanyuan Sword is enough to shake me?"

The voice of the leader of the Dark Sect was low and cold, filled with endless mockery.

"you are too naive."

As soon as he finished speaking, he waved the scepter again, and the evil energy around him swept towards Lu Yuan and the other two like a flood.

"Beware!"

Chu Yao shouted and quickly swung her sword towards the evil spirit, trying to resist this strong impact.

But the power of evil was too strong, and the sword's energy could not be completely resisted and was swallowed up in an instant.

"These evil spirits are too strong!"

Ye Ling'er's face was pale and the dagger in her hand was shaking slightly.

She could feel that this evil energy was far stronger than any enemy she had encountered before. It seemed to come from the depths of hell, carrying with it endless destructive power.

Lu Yuan frowned, and the Xuanyuan Sword in his hand burst out with strong light again.

"Don't panic! We have to stay calm."

He said, his eyes showing endless determination.

"Although the leader of the Dark Demon Sect is powerful, he still relies on evil energy. We can find his weakness."

Lu Yuan knew very well that for people like the leader of the Black Demon Sect, their power came from evil energy and there must be a core source.

As long as the source of that power is destroyed, his strength can be weakened.

"Ling'er, Chu Yao, the two of you cover me, I'll look for his weakness."

Lu Yuan made a quick decision and swung the Xuanyuan Sword lightly in his hand. The strong sword energy instantly slashed around and temporarily forced back the evil spirit.

Ye Ling'er and Chu Yao nodded and quickly dispersed. The daggers and swords intertwined into light, trying to block the evil energy that kept pouring in.

Lu Yuan stared at the leader of the Black Demon Sect and walked quickly forward, trying to get closer to him.

"Haha, Lu Yuan, you are very courageous."

The leader of the Black Demon Sect sneered, then swung the scepter in his hand violently, and the air was suddenly filled with a stronger evil spirit.

The evil spirits seemed to have life, condensing into countless black chains that instantly wrapped around Lu Yuan's body.

"Bondage?"

Lu Yuan snorted coldly, and swung the Xuanyuan Sword suddenly. The sword energy cut through the chains like lightning.

But the power of the chains is so strong that even if they are cut by the sword energy, they will quickly regenerate as if they are endless.

"These chains are similar to the previous forbidden techniques."

Lu Yuan thought to himself.

He had encountered similar sorcery on the altar of the Dark Demon Gate. The black chains were specifically used to restrain and weaken the enemy's power.

"But this time, I won't be trapped again!"

He gritted his teeth suddenly, and the Xuanyuan Sword in his hand burst out with an even brighter light, and the sword energy went straight to the core of the chains.

"boom!"

The strong fluctuations of spiritual energy shook the surroundings, and the black chain finally began to crack, and then it broke apart and turned into countless black mists and dissipated.

"Success!"

There was a sharp flash in Lu Yuan's eyes, and the Xuanyuan Sword shook lightly in his hand, then pointed directly at the leader of the Black Demon Sect again.

"No matter how powerful you are, I will not back down!"

The face of the leader of the Black Demon Sect changed slightly. He did not expect that Lu Yuan's sword energy was so sharp that it could break through his chains.

"hateful!"

He gritted his teeth and growled, swung the scepter once again, and a strong evil energy gathered around him, transforming into a black barrier.

"You think you can stop me like this?"

Lu Yuan shouted coldly, and the Xuanyuan Sword burst out with strong sword energy again, heading straight for the black barrier. "Boom!"

The sword energy and the barrier of evil energy collided violently in the air, causing a deafening noise.

Although the black barrier was strong, it gradually began to crack under the power of the Xuan-Yuan Sword.

"Break it for me!"

Lu Yuan suddenly roared angrily, the light of Xuanyuan Sword became more and more dazzling, and the sword tip was approaching the core of the leader of the Black Demon Sect.

"Crack!"

The barrier finally collapsed completely under the impact of the sword energy. The body of the leader of the Black Demon Sect shook violently, and then he took several steps back, his face turning pale.

"You... can actually break my protective evil spirit?"

There was endless shock and anger in his voice.

Lu Yuan did not give him any chance to breathe. He swung the Xuanyuan Sword in his hand violently, and the sword energy swept towards the body of the leader of the Black Demon Sect like a storm.

"hateful!"

The leader of the Black Demon Sect gritted his teeth and suddenly inserted the scepter in his hand into the ground. The strong evil energy burst out again, as if it would swallow up the entire palace.

"You all have to die!"

His voice was filled with madness and malice, and then a strange red light began to flash on the scepter, as if summoning some powerful force.

"This power..."

Lu Yuan's expression changed slightly. He could feel that the evil energy in the air was rapidly condensing, as if an invisible force was gradually awakening.

"This is the ultimate forbidden technique of the Black Demon Sect - 'Blood Sacrifice'!"

Chu Yao said in a low voice, with a hint of shock in her eyes.

"He wants to use his life as a sacrifice to awaken the evil spirit in this forbidden technique."

Ye Ling'er's face was pale. She could feel the oppression in the air becoming stronger and stronger, as if even breathing had become difficult.

"We must stop him, otherwise the consequences will be disastrous!"

Lu Yuan clenched his teeth, and the Xuanyuan Sword in his hand burst out with an even stronger light.

He knew that once the leader of the Black Demon Sect successfully performed this forbidden technique, the entire martial arts world would be plunged into endless disaster.

"No matter what, we can't let him succeed!"

Lu Yuan let out a low roar, then quickly rushed towards the leader of the Black Demon Sect, with the tip of the Xuanyuan Sword pointing straight at the opponent's throat.

"Humph, you came just in time!"

The leader of the Black Demon Sect sneered, swung the scepter in his hand suddenly, and a strong evil energy swept towards Lu Yuan like a storm.

"clang!"

The Xuanyuan Sword and the evil spirit collided violently in the air, causing a deafening roar.

Lu Yuan's body shook slightly, and the strong impact made him take a few steps back, but his gaze remained firm, and the Xuan-Yuan Sword made a low humming sound in his hand.

"Today, I will put an end to you!"

He roared angrily, and the light of Xuanyuan Sword became more and more dazzling, and the sword tip was directly aimed at the vital point of the leader of the Black Demon Sect.

"boom!"

The sword energy slashed towards the leader of the Black Demon Sect like thunder, and the strong fluctuation of spiritual power instantly tore apart the evil energy around him.

The leader of the Black Demon Sect let out a shrill roar, his body trembling violently under the impact of the sword energy, and blood continuously flowed from the corners of his mouth.

"Damn it...Damn it!"

He screamed in pain, his eyes filled with endless hatred and despair.

"Do you think... this will end everything?"

"I am the thousand-year-old master of the Black Demon Sect... You can't... kill me!"

His voice became weaker and weaker, but still full of unwillingness.

Lu Yuan did not give him any chance to fight back. He gently swung the Xuanyuan Sword in his hand, and the tip of the sword went straight to his heart.

"puff!"

With a muffled sound, the sword pierced through the chest of the leader of the Black Demon Sect, and blood gushed out instantly. (End of this chapter)
