Apocalypse survivor Su Jinxi time-travels to a famine-stricken fishing village, picking up a sickly 'God of Wealth' right at the start—Ao Che, the crown prince of the sea clan, unexpectedly gaining the ability to hear the inner voices of all marine life. The two harbor their own secret agendas; one is single-mindedly focused on making money, leading her younger siblings to gather seafood and get rich; while the other only wants to hide his identity and take back his dragon ball, but unexpectedly turns into a 'full-time househusband' of the family, as the cold and aloof crown prince gradually melts into a petty-jealousy 'vinegar king'. The whole family works with one heart, and their days grow more prosperous by the day!
