Beast World Transmigration: I Start Out as a Male, Now What?

Damn! Everyone else transmigrates to the Beast World as delicate females surrounded by handsome men. Why did I transmigrate as a male?!

Fine, a male it is. But surely I'd get the System that's supposed to come with transmigration, right?

Unfortunately, it didn't show up until eighty years later, after he had grown up and become female.

Other people's Systems give them all kinds of flashy, powerful skills.

This lousy System only gives her useless skills: painless childbirth, milk production, and a baby rocking chair...

How is she supposed to reach the pinnacle of beastly power on her own like this???
