Su Qingyuan, a disciple of the Xuanchen Sect in the Canglan Immortal Region, was originally an extremely talented inner sect pearl, but she was framed by her senior brother Mo Yuan at the sect's grand ceremony, and was deposed from the Ling Mansion and thrown into a forbidden area. On the verge of death, she awakens to the fate of cannon fodder - she is just a stepping stone in the script of heaven, paving the way for Lin Yaoguang, the "daughter of destiny", and her twin brother Su Yechen will even be crushed to pieces to save her.
Filled with hatred, Su Qingyuan bound the villain development system and vowed to overturn the bloody plot. She used her poisonous skills to kill the love-minded senior brother and punish the ungrateful people. She also teamed up with her younger brother Su Yechen, who was gentle on the surface but was actually evil, to establish the Poison Lotus Pavilion in the wilderness to compete head-on with Lin Yaoguang and his dog-licking forces.
But they didn't know that behind the protection of heaven there was a conspiracy from the upper world - Lin Yaoguang colluded with the soul-eating demon general disguised as the God of War to seize the origin of Su Qingyuan's rebellion; the realm of the upper world even sent a law enforcement team to come, vowing to wipe out this pair of "against the heretics".
The crazy poisonous girl and her soul-eating brother, using poison as a blade and soul as a front, not only want to slay the way of heaven and destroy false gods, but also tear apart the shady curtain of the upper world and find their own path to the villain throne in the sea of blood in the fairyland!
