Prepare Son-In-Law

A blue star "cow horse" fell into a rift in time and space and traveled to another world. There is only one blind daughter in the Murong family, and they are looking for a son-in-law. By chance, the protagonist becomes the Murong family's alternative husband-in-law (preparatory son-in-law). The two fall in love with each other in the ups and downs of the business world, and eventually the lovers get married, and the family and career have a good harvest.
