Collect Monster Girl Compendium Entries to Make Your Wish Come True!

Zheng Xia was invited by the Monster Girl Compendium to another world, where he kept transforming into different monster girls to learn about their species and habits.

But why collect them? The Monster Girl Compendium said nothing, merely promising to grant him one wish once he had collected them all.

Zheng Xia gladly agreed and set out on this long journey.

But why is this other world so different from what he imagined?

From the start, he was captured by a witch for research and reduced to nothing but a shell. Then he watched the witch get instantly killed by a hero's brain-targeting magic, only to turn into a witch himself?

That would be bad enough, but why, while messing with the hero, was he mistaken for another hero, knocked out alongside him, and used as material to forge the ultimate hero?

Huh? Huh? Huh?

Can someone explain what on earth is going on in this world?

Never mind. Let the world go mad. As someone who transmigrated, I'll get bound to a System, and as a half-witch, I'll try to turn back into a man, toy with people's hearts, and show off whenever I feel like it.

If I see injustice, I'll draw my sword and strike a couple extra blows. My greatest joy in life is watching those arrogant geniuses kneel before me. It's definitely not because the System's rewards are tempting me.
