Assemble'....

Zaiden Archman. He’s the main character in my novel called ‘Awakener’s Dead Harem’.

As an author, I love it when my main character suffers and is depressed.

He’s the main character that I took pride in. With my novel about to end, I pushed myself to write the last volume.

However, what I never expected was that it would be the end of me too. When I opened my eyes again, I had become Vincent Dihart, an Extra in my novel, who is only mentioned a few times in the novel.

I then found out a sad truth about my Main Character that I took pride in. He has changed.

But only humans, without any obvious changes, seem to have fallen from the top of the food chain to the bottom of the food chain overnight.
Any creature that can open its mouth to eat can treat humans as food.
But fortunately, this world has not completely killed humans. Gradually, humans discovered that they had the ability to cultivate compatibility with other creatures.
As long as it has a high degree of compatibility with some powerful mutant creatures, it can be used for its own use to achieve the purpose of protecting itself.
Fang He is a person who is very compatible with mutant animals, but it is also because of his ability that he has changed from the strongest to the stupidest.
Fang He, who was reborn, said, “Hmph, this time…”
