Mythology Invades? How Strong Can a Little Kid Like Me Be?

Slice of life? Nearly invincible protagonist? The protagonist has no System, but others might. The Coming Storm arc (in progress), followed provisionally by these arcs, in no particular order: Blood Clan Resurgence, Glory of Hell, Heaven's Fall, Demon Realm Invasion, Starbound Journey, Undead Insectoid Clan... It might not all be mythology. There could be Western fantasy, sci-fi, xuanhuan, the supernatural, Systems, the Main God Space, and players. The author likes mixing everything together. Yi Xiaoke transmigrates into a world where spatial rifts appear at random, disgorging creatures and objects from the myths, legends, and folk tales of various countries. The authorities conceal the truth from the public. Some people awaken special abilities. These abilities are all over the map: some can hurl fireballs or unleash lightning, while others can summon weapons, from ordinary weapons to special weapons, melee weapons, and firearms. Some abilities are conceptual, such as forcibly making someone go bald, becoming invincible for one second, or making someone speak only in gibberish. As for the protagonist... hunting demons makes him stronger. I'm no good at writing blurbs. Please read the story. (The author has other novels too, if you're interested.)
