Destined Villain: Overthrowing the Male Protagonist Tianling Gai at the Beginning 1

[AI Generation] Travel through the world of Gaowu and become a noble prince of the Xuan Kingdom family on the surface, but in reality he is the heroine's loyal licker. The male and female protagonists regard the original protagonist as a stepping stone and eventually reach the sky in one step. In this case, don't blame him for flipping the table.
