Ji Qingzhou was anthropophobic and foolish. She had no redeeming qualities, except for her face.

Once she transmigrated, she was bound to a Guide System to save the world. She was tasked with capturing Shen Rongyu, the sinister, beautiful, mighty, gloomy villain and Great Shixiong of Xuanyun Sect, and to prevent him from destroying the immortal cultivation world in the future.
