Chinese Taoist Priests Travel Through the Battle to Exorcise Ghosts

Chinese ghosts are rampant. Zhang Wei, an otaku who dies suddenly in an Internet cafe, accidentally travels to Zhang Xuan, the successor of the old Celestial Master Qing Xuzi. The old Celestial Master teaches Zhang Xuan what he has learned throughout his life and becomes the last purple-robed Celestial Master. The protagonist, as the "last purple robe", shoulders the ultimate mission of revitalizing the Taoist sect, sweeping away the demons, and guarding the world.
