Ancient Marriage System Rewards Beautiful Women

Modern civil engineer Yang Feng transmigrates into a war-torn era as a soldier with the same name, accidentally binding to a 'Concubine System'. Coinciding with the government's forced marriage decree, he shelters three extraordinary women: Liu Yiyi, Ji Rubing, and Xie An Yue. Using modern items exchanged via the system, he builds a new house overnight and uncovers a gold mine behind the mountain with an excavator, successfully resolving the debt demands from the Zhao landlord and the government's harassment. However, new crises arise when Ji Rubing's younger sister, Ji Ruyan, impersonates an orphan to infiltrate the household, framing Yang Feng for indecent assault. Fortunately, the system's provided lie detector exposes her conspiracy.
