Jiang Shuyao, a tough and money-loving B&B owner, was accidentally bound to the Wanjie Trading System at a critical moment when his B&B was demolished. In order to preserve the "time house" left by her parents, she used modern materials to receive visitors from other worlds, and successively rescued Xiao Heng, the dying war god of Dajing, and Chu Qingyue, the concubine's princess, helping the former reverse the war and the latter ascending the throne as empress. Faced with repeated sabotage by Huang Youjin and others of the Jinshui Group, Jiang Shuyao relied on system defense and help from other worlds to resolve them one by one. Finally, she held on to the B&B and achieved wealth freedom through plane trade, becoming the strongest middleman across the two worlds.
