The Devil Fruit Era: I Awakened the Copy Fruit from the Start

This is a wasteland world eerily similar to One Piece.

Every living thing awakens a Devil Fruit ability at birth. Animals that gain immense power have driven humanity from the homes it once depended on to survive. People can only control enormous steel cities and flee from the animals' attacks.

These powerful animals have not only awakened Devil Fruit abilities just like humans, but can also use all three types of Haki. Some animals that awaken the Human-Human Fruit can even use Sulong.

Chuan Jianguo transmigrates to this world.

He awakens the Copy-Copy Fruit ability, which lets him use the moves of known Devil Fruit users.

And that is not all he has besides his Devil Fruit ability.

He also has a System.

It lets him exchange experience for attribute points and skill points.

He can even reset his companions' Devil Fruit abilities.

What's more, he can grant himself and others a second or even third Devil Fruit...
