I was supposed to save lives and heal the wounded, but things in the world are unpredictable, and my hands were eventually stained with the blood of revenge. The originally bright red blood had been soaked with poison and turned black, just like the pitch-black night. Since you have pushed me into the abyss step by step, then no matter what, I will make sure there is no more daylight in this world! --Bai Zhuan
