The three best anime works that I have ever seen are Attack on the Giant, Your Name, and Spirited Away.
" The Attacking Giant " was a horror anime set in the background of a war between humans and giants. The story was thrilling and the characters were vivid. It was a very classic anime.
" Your Name " was an anime with a love story between two young people as the main theme. The movie version had won widespread praise around the world. The plot was romantic and touching, and the exquisite graphics were a very worthy anime.
" Qianxun " was a story with Qianxun as the main character. It narrated her adventures in a mysterious world. The plot was profound and the pictures were exquisite. At the same time, it also explored the theme of the human heart. It was a very worthy anime.
I'm pretty sure they don't fight. The comic's plot doesn't include a battle between them. Maybe in some alternate version or fan-made story, but not in the official comic.
Battle Through the Heavens was not made into an anime. Battle Through the Heavens was a popular fantasy novel that told the story of the protagonist Yun Fan's rise in cultivation. Although there were rumors that the novel would be adapted into an anime, there was no official confirmation.
