The apocalypse is coming. Superpowers, space mustard seeds, appear frequently. In order to survive, they all come up with strange tricks. Desire changes people's hearts. Living is the truth. But other people's superpowers are great. What's the matter with my gender-changing superpower? Other people's space mustard seeds collect things, grow food, raise chickens and ducks, bring out spiritual springs, and elixirs. I can only use this as a water hyacinth. I can't use it like this in the end of the world.
