I recommend "Apocalypse Umbrella Fairy" to you. After the apocalypse, humans and animals were given the opportunity to evolve. Human firearms gradually withdrew from society, and the return of cold weapons led to the reappearance of 18 martial arts. However, among all the people who used cold weapons, only one person used an umbrella as a weapon. He was the Umbrella Immortal Liang Mu. I hope you like my recommendation. Muah ~
