The Live-in Son-in-law of Jiangning

On the night of his wedding, Lin Zhexuan is transported through time, only to be cuckolded and nearly choked to death. He uses a government contract to take control of the Zhao family, takes over the West City restaurant, and boldly renames it the Son-in-law Restaurant. He applies modern KPI management to ancient dining, making his employees work hard while he relaxes. Rivals use dirty tricks and collude with officials to suppress him, forcing his staff to fight fiercely. He spends money to build his reputation and protects his people to the end. Eventually, all the merchants in the city tremble in fear, and no one dares to provoke him again! While other live-in sons-in-law endure humiliation, he proudly hangs his sign and runs his business openly, raising a group of fiercely loyal followers to dominate the streets of Jiangning! — Description from novelcodex.org
