Who is the real overlord on earth?

Human beings who claim to be the spirit of all things?

But when bees stop collecting honey, human civilization will come to an end.

Perhaps one day aliens will come, they may not necessarily study human society, but they will definitely study insect society.

This kind of little thing is all over the world, and it has a greater number than other biological species.

Its every move affects the balance and prosperity of the world’s ecology.

As an envoy of the Younv family, Meiji can manipulate genes, copy, transplant, and even transform and optimize.

In the ninja world, genes are also read as blood succession limits.

“Sa, feel the horror of the swarm.”

I am the swarm!
