I shall become a man amongst men and a god amongst gods

A young man in his 20s was hit by a truck and reincarnated without a system how will he survive in this new world. There will be harem in this story obviously there will be lemon with some romance and possible gender benders for the freaks out there I'm not judging I like it too. There will be time skips and the world will progress from ancient times to modern life and alternate worlds and MCs children will also grow up and his descendants will also be featured but won't have much screen time hope you enjoy.
