The girl touched it, and the girl's clothes disappeared, and the gauze appeared on the girl's body. Moreover, when there was only a boy, the gauze appeared. When there were other people, it was the old clothes. Later, they went out and arrived at a place. Many people wanted the girl, and the boy often accepted challenges from others.
I still haven't found it, I beg you!

Answer 1

I recommend the Eastern fantasy novel,"Lovesickness on the Other Shore", to you. The plot of the story was that the protagonist, Hua Fuxi, was guarding a Crimson Demon Pagoda. Unexpectedly, one day, the Crimson Demon Pagoda was destroyed and thousands of demons fled in all directions. Thus, Hua Fuxi embarked on a journey to collect demons. She was trapped in the tower with a girl and began the story of the tens of thousands of demons on the long road of collecting demons. Not only did it have the flavor of immortal cultivation, but it also had a strong romantic color. It was simply a good book that could not be missed! I hope you like my recommendation. Muah ~
