Zhao Fan, who had transmigrated to the immortal cultivation world for eight hundred years, was sent back to the modern city due to insufficient cultivation. Endowed with Nascent Soul cultivation and mastering medical skills, spellcraft, and various other sect abilities, he possesses extraordinary abilities in the ordinary city. After returning, Zhao Fan protects his dependent younger sister Zhao Ling'er, cures difficult and stubborn illnesses with exquisite medical skills, fights against evil and malefic curses, and punishes evil underworld figures and arrogant young masters. Adhering to his bottom line without abusing his power to kill indiscriminately, he uncovers the cultivation talents of those around him, guides everyone in righteous cultivation, maneuvers among prominent families and the martial arts community, explores ancient cultivation relics on Earth, and kicks off a brand-new story of urban immortal cultivation.
