Business genius Xu Yun Long is highly regarded within the group, arousing intense jealousy from Zhang Feng, the son of the chairman. For a smooth succession to power, Zhang Feng seduces Xu Yun Long's wife to cheat on Xu. Then, they set up a scheme to ruin Xu's reputation together and subject him to various torments before tossing him into the river. However, justice has long arms, which allows Xu to get away with it by a fluke. From then on, he adopts the alias "Wu Er Gou" and starts from scratch as the poor son-in-law of a noodle shop's owner. With determination and resilience, he embarks on a journey of entrepreneurial success, vowing to defeat Zhang Feng and make a comeback in the business world. Adapted from the web novel "Gai Xu" (丐婿) by Nan Gu Yan (南孤雁).
