In his previous life, he was a boy. Now he's transmigrated into the female antagonist of the protagonist's game, The Cultivation Journey of the Righteous Senior Brother: Yue Xi, an evil Blood Demoness who has done every wicked thing imaginable.
And he's appeared at the worst possible moment, just as the righteous senior brother Xiu Tianqing is hunting her down and she's about to be defeated as an early-game antagonist.
