Unscientific Martial Arts Training

There are countless demons and monsters in the world. Or howl and gather in the mountains, use explosions to burn, kill and loot; Or they may hide in the human world and use evil tricks to cause harm to people's hearts. All living beings are suffering, and we can only overcome it by ourselves. Use the body as the boat and the spirit as the rudder; With the knife in his hand and the breath in his chest, he can create a bright universe.
