Impoverished young woman Su Xiaoxiao receives a gift from the God of Wealth: a two-way portal connecting the ancient and modern worlds. Desperate to save her seriously ill mother and repay their debts, she becomes a trader across time. By exchanging cheap modern everyday goods for ancient gold, silver, and antiques, she makes her fortune through antique auctions, pays off her debts, and cures her mother. Along the way, she befriends an ancient man named Lin Dayong and takes on greedy relatives and villains involved in cultural relic smuggling. Later, she is appointed a special consultant at a cultural relic protection center, traveling between the two worlds to recover lost national treasures while balancing her family responsibilities with her duty to her country.
