Reincarnated as a Son of the Sword Saint and the Sage

"You are chosen to be reincarnated in this era." A plain 17-year-old high school boy involved in a truck-kun incident met a goddess upon waking up. He was given abilities that he wished for and was reborn as the son of an aristocratic family. He found out that his parents were actually the strongest couple on the continent. But that's not the thing for which he was shocked. He discovered that both his biological parents were actually women?! With his cheat skills, he will live his life as much as he pleases and build a nation in the process.
