The System Tycoon's Revenge

Nineteen-year-old Finn Carter is forced by the Carter Clan to marry Yara Hale, who is pregnant with another man's child.

With massive resources in hand, he repeatedly humiliates members of the Carter Clan, the rival Hale family and various business enemies, takes over multiple leading enterprises one after another, thwarts commercial plots and kidnapping crises, uncovers the mastermind behind his family, rescues his imprisoned parents, eventually dismantles both the Carter and Hale clans, holds 200 billion in assets to become the richest man in the Southeast, and stays together with Shawnee Shaw.
