In modern times, Li Guanqi, who possesses the ancient Purple Jade, accidentally time-travels and becomes a dissolute heir of the Great Zhou. After being plotted against and having both legs completely crippled, he awakens the supreme ancient treasure, the Purple Jade, which can swallow everything and refine cultivation techniques and power. Disguising himself as a cripple to bide his time, he marries the eldest princess, Su Mingyue. Undercurrents surge in the imperial court, demons run amok in the southern frontier, and the idle prince plots rebellion. At the Wuyao Grand Ceremony, he displays astonishing literary and martial talent, after which he rushes to the southern frontier to rescue his wife trapped in a desperate situation, single-handedly slaying the demon lord. Coinciding with the unravelling of the ancient secret of the Nine Provinces splitting, the Nine Provinces merge into one, and forces from the upper realm descend. Li Guanqi uses the power of the Purple Jade to fight formidable enemies, stepping step by step onto the path of an earthly immortal.
