Kendo Modifier

This is a strange world. The biggest threat to human survival is not war and disease, but some weird things that ordinary people cannot understand. Shrouded in terror, Ren Feng relies on a modifier that can improve various sword skills, learns various swordsmanship, forges thousands of swords, controls endless sword formations, and masters mysterious sword intentions, and embarks on a path of transcendence in the shadow of despair. "As long as it's related to swords, I'll show it to you!"
