Song of Broken Knife in the Night of Industry

He was abandoned in a river at the age of seven, and his master died tragically at the age of seventeen. Xiang Liuer walked out of the ruined temple with only three things on him: The old man's broken knife, the bloody work that killed him for half his life, and the sentence "Don't commit murder again." But in this world, kindness cannot buy you a way to survive, and your duty cannot stop you from being chased. The royal family wants him dead, the world wants him dead, and even the world cannot tolerate this evil skill. Then - use killing to stop war, use severity to control violence. The broken sword is recast, and the bloody skill is used again, and it is invincible.
