The Nine Revolutions Star Art

I wouldn't have been able to write such a magical book if I hadn't had cerebral thrombosis for ten years.

By reading the introduction, I learned that the protagonist, a cripple, must have an opportunity to counterattack. Now I am the villain in the book, killing the pig horns, seizing the opportunity, and starting the villain's journey against the heavens.

It's written and written and gone, and there's no ending either.
