A Cold Sword

The light of a sword is cold, and the world is silent. When he was young, Lan Yi had a fiancé. His nature was cold, as frosty as snow, but he was somewhat gentle towards her. But then he wanted to kill her, and he actually did it. But it doesn't matter - if he kills her once, she will kill him a thousand or a hundred times. *Cp: Crazy criticism of Bingshan x uninhibited "evil" girl
