Rose Lord

Sebastian Hale, The Wolf of Wall Street, is caught in a thunderstorm on a private flight and crashes into a forest in northern England. When he opened his eyes, he found that he was the illegitimate son of a dying baron in the Northumbria territory - with the same name and surname, but penniless. This is the twelfth century, the law is the will of the lord, and wealth is worth less than a good sword. He used modern financial knowledge to defeat the knight leader at a lord's banquet and got the first pot of gold. He used double-entry accounting to check the territorial accounts, used the concept of options to play with the wool trade, and used gunpowder formulas to blow up blockades. The nobles laughed at this "merchant lord" until his silver coins circulated throughout the North. And the cold and arrogant duke's daughter-in-law, Elalyn Montgomery, was looking at him with the eyes of a prey.
