At the End of the World, a Knife and Equipment at the Beginning All Rely on Cutting

The end is coming People are in panic, monsters are coming All the laws of the world are destroyed and returned to the original state Peeling away the superficial veil, is this an invasion or a game played by a high-ranking person? We don't know, but we can only pick up the knife in our hands and fight out the bloody road - the road home. (Contains Honkai Impact)
