Late at night on a snowy night, outside the Tianjing death row. Chen Xiao crawled out from the pile of corpses, covered in blood, holding a broken sword tightly in his hand. He was wearing a prison uniform, and his wrists had scars from the chains. He didn't remember how he survived that night. He only remembered - Qingyun Villa, 371 lives turned into ashes. And he wants those who are still alive to pay with their blood one by one.
