Kuiba: You Mi Kuang

The defenses of the Linyao Altar were breached. Qi Heng San, You Mi Kuang, and the enemy were all consumed by the light. Its appearance altered the surrounding pulse frequencies, and curved mirrors appeared around the Linyao Altar. You Mi Kuang fell into one of them... As he lay unconscious, he saw his comrades Bai Luoti, Feng He, Ying Song, Huan Zejin, and Guang Xiu. He also remembered what he had said to Kui Ba: “Even if I can't defeat you, I'll make my position clear through my actions. I am your enemy, your mortal enemy! Your opponent is You Mi Kuang, the Fog Demon night combat vanguard of the Seventh Division in the Eastern Theater of the Lingshan Army.”
