Transmigrated as a Live-in Son-in-Law, I Can Still Make It on My Own

Trying to save a beautiful married customer, a small-time street vendor who had gone bankrupt and failed in business is struck and killed by an out-of-control car. His soul remains intact and drifts to a dynasty absent from the history books. After being rescued from a river and waking up, Zhang Xiaosheng discovers that he has possessed the body of a useless live-in son-in-law. His predecessor had signed a three-year contract that is about to expire. In this ancient era, which does not appear in any history book, his knowledge of the future is completely useless. With neither the imperial examinations nor powerful connections to rely on, how can he survive in this dynasty? Should he jump into the river again? Even if his soul manages to travel back, his body will probably be nothing but a pile of rotting flesh by then. He has no choice but to abandon the idea. After thinking it over, he realizes that, fortunately, he still has his memories from the future. He can only rely on what little he has left to survive in this turbulent dynasty. Looking at the beautiful married woman who saved him and her maid, he wonders whether he should offer himself in marriage in exchange for a place to stay, so he can at least survive in safety for now...
