Transformation
Running the Asura Tactics, his eyes turned a blood-red color and his jet-black hair turned fully white. At the same time, a black aura of slaughter flowed around his body.

This physique was attained after practicing the Asura Tactics – the Body of Asura, but this was only the initial stage transformation. According to the explanation on the piece of note, once Huang Xiaolong mastered the highest level of Asura Tactics, he could transform into a real Asura.
