I'm the Animal World's Soft O-Type Daddy (Quick Transmigration)

You probably won’t believe this, but I’m a man who turned into an animal and got pregnant. ① A delicate, pampered Omega Akhal-Teke stallion bottom × an equestrian champion, the great demon king top. Ye Zhen, a beast tamer in the apocalypse, opens his eyes to find he’s become an Omega Akhal-Teke stallion, with a lustrous, brightly colored coat and noble bloodlines. The owner of the estate takes meticulous care of him, but then he experiences his first heat. His owner finds him an Alpha horse, and he’s taken by a black stallion. Ye Zhen: “...” After a lifetime of taming beasts, he’s ended up becoming one. That’s not even the worst part. The worst part is that he gets pregnant soon afterward. Unable to put up with the hardship, Ye Zhen escapes the estate and runs into the wilderness, where he gives birth alone. He runs away with a baby on the way. To raise his little one, he risks dealing with tigers, fights lions, and lives among wild beasts. His baby becomes the darling of the animal kingdom. He thinks the big shots just like his baby, but when his next heat comes, the beasts fight viciously over the right to be his mate. Then a black stallion arrives and defeats every beast, winning the right to be his mate. Black stallion: “You dare touch my wife? You’re asking to die!” Ye Zhen: “...” ② A proud herbivorous dinosaur bottom × a Tyrannosaurus rex top, ruler of the plains. ③ A beautiful deep-sea merfolk bottom × a fierce, powerful merfolk lord top. … Later, no matter what he transmigrates into, he can’t escape this fate and is forced to raise a baby. And in every world, he has a ridiculously strong Alpha lover from the animal kingdom. Ye Zhen: “...It’s not so bad, I guess. Other than the effort it takes me, my lover is gentle and considerate, and the baby is adorable and well-behaved. I’ve accepted this absurd fate.” * 1v1, the top is split into incarnations. The story of a soft Omega from the animal kingdom and his fierce Alpha lover. * The bottom is a pretty airhead, clueless about romance but great at handling everyday life. * Mostly a gentle, everyday story with a slow pace and gradual development. A mountain of original worldbuilding. Theme: A rich store of knowledge helps you survive.
