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

Lu Yuan's sword energy turned into a golden stream of light in the air, heading straight for the last batch of undead.

With a loud bang, the vengeful spirits summoned by the Black Demon Sect turned into black mist and dissipated between heaven and earth.

"Finally cleared out these undead."

Lu Yuan secretly breathed a sigh of relief, but his expression was still tense.

He knew that the battle was not over yet and the real danger was still ahead.

The right protector fell to the ground, his face as pale as paper, blood constantly flowing from the corner of his mouth.

He stared at Lu Yuan with resentment in his eyes, obviously unwilling to see himself end up like this.

"Do you really think... you can defeat our Black Demon Sect?"

His voice was hoarse, carrying the last trace of resentment and madness.

Lu Yuan looked at him coldly, the Xuan-Yuan Sword trembling slightly in his hand, as if it could take the other's life at any time.

"You, the Black Demon Sect, have been causing trouble for many years. Today is your end."

Lu Yuan's voice was cold and emotionless.

He knew that evil people like the Right Protector would never repent easily.

To such an enemy, mercy would only bring greater threats.

"Huh...ridiculous."

The right protector sneered, and suddenly inserted the long staff in his hand into the ground, and the strong evil energy burst out from his body again.

"Do you think...I will just sit there and wait for death?"

As he chanted the spell, the ground began to shake violently, and a huge black beam of light gushed out from the ground and rushed straight into the sky.

"what?"

Lu Yuan instantly felt an unprecedented strong sense of oppression.

He swung his sword quickly, trying to stop the evil spirit from spreading.

But the power of the black light was so strong that even the sword energy of the Xuanyuan Sword could not completely suppress it.

"This is the ultimate forbidden technique of the Dark Devil Sect - sacrifice!"

The right protector's laughter became more and more crazy, and blood kept flowing from the corner of his mouth, but he seemed to no longer care about his own life.

"I will use my life to summon the strongest evil spirit of the Black Demon Sect!"

"By then, the entire martial arts world will be under the control of the evil spirit!"

As his words fell, countless black cracks began to appear in the sky, as if the entire world was collapsing.

The strong evil energy surged in all directions like a tide, and the entire ancient city was instantly shrouded in this evil energy. The world seemed to have fallen into endless darkness.

"This power..."

Lu Yuan's expression became more and more solemn. He could feel that this evil spirit was far stronger than any enemy he had encountered before.

"Is this the last resort of the Dark Sect?"

Ye Ling'er and Chu Yao were also shocked by this strong evil energy, and there was a hint of fear in their eyes.

"Brother Lu Yuan, what should we do?"

There was a hint of panic in Ye Ling'er's voice. She held the dagger tightly and looked at Lu Yuan anxiously.

Chu Yao's face was also a little pale. Although she tried her best to stay calm, the fear in her heart was still nowhere to hide.

Lu Yuan took a deep breath and quickly calmed his mind.

He knew that he must not panic at this time.

“We can’t back down.”

Lu Yuan's voice was low and firm, and the Xuan-Yuan Sword in his hand burst into an even brighter light.

"No matter how powerful this evil spirit is, we must fight to the end."

"Only in this way can we completely put an end to the Black Demon Sect's conspiracy."

After he finished speaking, he swung his sword violently, and the golden sword light cut through the darkness like lightning, heading straight for the core of the black light column.

"Want to stop me?"

The voice of the Right Protector was full of madness and disdain.

"You have no chance."

"The coming of evil spirits is an irreversible fate!"

As his words fell, the black light column suddenly vibrated violently, and then a huge figure emerged from it.

It was a gigantic evil spirit, its body wrapped in thick black fog, its eyes like blood-red flames, emitting endless murderous intent and resentment.

"Is this the evil spirit worshipped by the Black Demon Sect?" There was a hint of coldness in Lu Yuan's eyes. He could feel that the power of this evil spirit was extremely strong, far exceeding any enemy he had encountered before.

"This evil energy... is so powerful."

Chu Yao's face became paler and the sword in her hand trembled slightly. It was obvious that she had felt the oppression brought by this evil spirit.

"We must be careful. The power of this evil spirit may be far beyond our imagination."

Ye Ling'er also spoke nervously, the dagger in her hand flashing coldly.

Lu Yuan was not frightened by the power of this evil spirit, his eyes remained calm and firm.

"No matter how powerful it is, we must kill it completely."

"Only in this way can this all end."

After he finished speaking, he swung the Xuanyuan Sword in his hand violently, and the sword energy rushed towards the direction of the evil spirit like a violent storm.

"boom!"

The sword energy and the power of the evil spirit collided in the air, causing a deafening roar.

However, the power of the evil spirit was too strong. Although Lu Yuan's sword energy could tear its shell, it could not completely destroy it.

"The power of this evil spirit is so difficult to destroy."

Lu Yuan frowned and thought secretly in his heart.

But he knew that he must not back down.

"Continue the attack!"

Lu Yuan let out a low shout, and the Xuan-Yuan Sword in his hand burst out with a strong light again, with the tip of the sword heading straight towards the direction of the evil spirit.

Ye Ling'er and Chu Yao also attacked at the same time. The dagger and the sword intertwined in the air to form a light, and slashed down towards the evil spirit fiercely.

"boom!"

The three forces exploded at the same time, and strong spiritual energy fluctuations instantly spread.

But even so, the evil spirit still stood firm, with even more violent murderous intent and resentment revealed in its eyes.

"This force... is too strong."

Ye Ling'er's breathing became a little rapid. She could feel that the power gap between herself and the evil spirit was too big.

Chu Yao's face also turned pale. She knew that if she continued like this, she would never be able to defeat the evil spirit.

"Brother Lu Yuan, this is not a solution for us."

She said anxiously, with helplessness and uneasiness in her eyes.

Lu Yuan clenched his teeth and thought to himself.

He knew that he had to find a more effective way to completely defeat this evil spirit.

"Xuanyuan Sword... Is there really no other way?"

Lu Yuan murmured softly in his heart, and then injected all his spiritual power into the Xuanyuan Sword again, trying to awaken the hidden power in this ancient sword.

However, although the light on the sword's blade was dazzling, it still could not completely suppress the power of the evil spirit.

"Damn it, is it really impossible to defeat it?"

Cold sweat broke out on Lu Yuan's forehead and his heart was filled with anxiety.

At this moment, he suddenly felt a weak power surging from his body, as if it was some mysterious call.

"This is……"

Lu Yuan's heart trembled, then he closed his eyes and quickly felt the source of this power.

He soon realized that this power came from the resonance between him and the Xuanyuan Sword.

"Could it be that the Xuanyuan Sword still has power that has not yet fully awakened?"

A glimmer of hope arose in Lu Yuan's heart, and he immediately concentrated all his spiritual power on the Xuanyuan Sword, trying to completely awaken the true power of this ancient sword.

"Wake up!"

He roared suddenly, and the Xuanyuan Sword in his hand suddenly burst out with a stronger light, and an ancient rune faintly appeared on the blade.

With the appearance of runes, the light on the sword became brighter and brighter, and the whole world seemed to be shrouded in this light.

"This power..."

Ye Ling'er and Chu Yao were both shocked by this sudden burst of power, and endless surprise appeared in their eyes.

Lu Yuan slowly opened his eyes, with an extremely determined light flashing in his eyes.

"The true power of the Xuanyuan Sword has finally awakened."

He whispered. (End of this chapter)
