He suddenly pounced towards Su Yan at lightning speed, his curved blade flashing with cold light, carrying a deadly threat.

Seeing this, Su Yan quickly dodged to the side, and at the same time a sharp sword appeared in his hand, ready to meet Illidan's attack.

The two men engaged in a fierce confrontation in an instant. Their movements were fast and sharp, and each attack contained endless power.

sonorous!

The sound of attacks breaking through the air continued to ring out. Su Yan and Illidan attacked back and forth, neither of them giving in. Their eyes were filled with fighting spirit and determination, as if they were determined to defeat the other.

Each collision triggered a powerful energy wave, and the surrounding air seemed to be torn apart. Su Yan's swordsmanship was sharp and precise, while Illidan's attacks were full of power and dominance.

Neither side was willing to give in to the other, and both were convinced they could defeat their opponent. They used their fighting skills and strategies to the fullest, making the duel extremely fierce.

Finally, after a hard-fought battle, Su Yan won with a slight advantage. His swordsmanship was more sharp, and he found Illidan's weakness and successfully broke through his defense.

Puff! Illidan spat out a large mouthful of blood, his entire body trembling violently, his eyes filled with astonishment and confusion: "I...what's wrong with me? Why is this happening all of a sudden?" He tried to struggle to stand up, but his body refused to obey, as if suppressed by an invisible force.

Su Yan slowly walked up to Illidan, a cruel smile on his face. His voice was icy and heartless: "You're going to die soon! I hope there's no disaster in Hell!" Illidan's eyes widened, filled with resentment and anger. However, he could no longer resist and could only watch himself die.

With a swoosh, the longsword in Su Yan's hand suddenly became incredibly sharp, flashing with a cold light. With a powerful swing, he thrust the sword straight into Illidan's chest, piercing his heart. Illidan let out a painful scream, his body trembling violently.

As the longsword pierced through him, Illidan's life force quickly dissipated. His eyes gradually lost their luster, and finally, his head drooped in weakness. Su Yan pulled out his longsword, and Illidan's body fell to the ground, his blood staining the surrounding ground red.

Su Yan glanced coldly at Illidan's corpse before turning and walking away. He held no mercy in his heart, only ruthlessness and determination towards his enemy. The battle ended with Illidan's death, and Su Yan continued on his way, searching for his next target.
