Missing Each Other on the Other Side

(This book is also called "The Story of Ten Thousand Monsters"). There is a tower on the east border, and there are countless monsters in the tower. It's all guarded by one person, and the person guarding the tower is Hua Fuxi. One day, the Crimson Demon Tower was destroyed and thousands of demons emerged. Hua Fuxi embarked on a journey to collect the demons... Short version: The story of the flower girl's long journey to collect demons and the ten thousand demons. I like short unit stories that are similar to quick travel.
