Fen Tian Goes Against the Path

World view: The cruel world of immortality, the weak eats the strong, the righteous is hypocritical, and the devil is rampant. Power system: Burning Heaven Technique (use pain as fuel, hatred as fire, each level needs to be sacrificed to sacrifice an emotion or physical function). Character relationships: Lin Mo (the crazy avenger) and Yun Cang (the old monster who cheats) fall in love and kill each other; the "redemption and destruction" pull with the heroine.
