Rise of the Otherworld.

The battle between Lin Yu and the black shadow became more and more intense. The shock wave generated by the collision of their spiritual power broke the surrounding trees and sent sand and rocks flying all over the sky. The originally peaceful valley was now like a storm raging in a mess.

Lin Yu gritted his teeth, pouring all his strength into every move. His sword skills were sharp, and his sword style was like a gust of wind and rain, with an unstoppable momentum. However, the black shadow's body movements were extremely strange, and he always managed to avoid Lin Yu's fatal blows at the critical moment. The black shadow was like a ghost, shuttling between Lin Yu's attacks, and from time to time he would launch a counterattack, making Lin Yu unable to defend himself.

"Damn it, who is this guy!" Lin Yu cursed in his heart. His forehead was covered with sweat, which slid down his cheeks and dripped into the dust under his feet. But his eyes remained firm, and he showed no intention of retreating.

Tang Feng and the others were extremely anxious, but they could not intervene. They could only watch the battle anxiously, their eyes filled with worry and anxiety.

The magic woman kept trying to cast spells to interfere with the black shadow, but the black shadow seemed to have a strong resistance to spells. When the light of the spell approached the black shadow, it was blocked by an invisible barrier and the effect was minimal.

"Everyone, come together! We can't let the Sect Master face this alone!" Tang Feng shouted, rushing forward first. His face flushed crimson with anger, and the sword in his hand flashed with fury.

The other disciples responded, desperately rushing towards the shadow. Their cries echoed through the valley, filled with a determination to die.

However, the black shadow simply waved his sleeve, and a powerful force surged out like a surging wave, knocking them all away. The disciples fell heavily to the ground, blood spurting from their mouths.

"You don't know your own limitations!" The black shadow sneered. His voice seemed to come from the abyss of Hell, full of disdain and ridicule.

Lin Yu took advantage of the shadow's momentary distraction and launched a full-force attack. The sword shone brightly, like a blazing sun, piercing straight into the shadow's chest. This strike condensed all of Lin Yu's strength and hope, carrying a desperate momentum.

The shadow leaned slightly to the side, leaving only a shallow wound on his shoulder. Blood oozed from the wound, but the shadow didn't care, instead revealing a playful smile.

"Hmph, you have some skills." A hint of surprise flashed in the black shadow's eyes, but this surprise was instantly replaced by indifference.

Lin Yu, however, did not feel the slightest bit of joy, because he knew that such an attack could not reverse the situation at all. His breathing became rapid, his physical and spiritual strength were rapidly depleted, and each attack became heavier.

At this time, Lin Yu's physical and spiritual strength were rapidly depleted, but the black shadow was still at ease. Lin Yu's clothes were already soaked with sweat, and his body was covered with wounds of all sizes, but he still persisted tenaciously.

"Am I really going to die here today?" Lin Yu felt a trace of despair in his heart. But this trace of despair was only a flash, and he quickly dispelled it, and his eyes became firm again.

"Even if I die, I won't let you succeed!" Lin Yu roared and attacked again. His sword flashed through the air, and each sword carried his unyielding will.

At that moment, a strange sound suddenly rang out from the sky. It sounded like an ancient horn, deep and powerful, awe-inspiring. Then, a brilliant light descended from the sky, illuminating the entire valley.

The black shadow raised his head slightly and looked at the sky, and for the first time a solemn expression appeared on his face.

Lin Yu was also attracted by this sudden change, and a glimmer of hope ignited in his heart.

In the light, a mysterious figure gradually emerged.

Who is this person? How will his appearance change the course of the war?
