Travel Through Another World and Dominate the Dynasty

He, a history teacher who retired from the special forces, came to a different dynasty in a thousand-year reversal of time and space. He originally wanted to be the heir to the county king with peace of mind, but his stepmother's dislike, his elder brother's jealousy, the decay of the dynasty, and the invasion of foreign races forced him to dominate this world and become a true emperor.
