A modern corporate drone time-travels to become An Zizai, the ninth prince of Great Chu, awakening a god-tier talent that makes him infinitely stronger just by sunbathing and eating good food. He inadvertently wins over a group of experts, including the eunuch Xiao Guizi and the white-haired sword immortal Li Hanyue. Amidst the imperial princes' internal power struggles, remnants of the previous dynasty collude with the White Lotus Sect and centuries-old fiends plotting to overthrow the realm, leaving the capital fraught with danger. An Zizai hides his true strength, appearing to slack off while actually harboring compassion for all living beings. Casually using meager spiritual power to resolve crises, he promotes high-yield crops to relieve disaster victims and enlightens the lost. Unflinchingly shattering all rebellious plots, he lives a carefree and secluded life in the mortal world, guarding the peace and stability of the common people of Great Chu with gentle strength.
