A simple science fiction film suitable for dark viewers with 3 bodies. The existence of civilization does not necessarily rely on itself, it may just be a more powerful existence that needs you. If you can return to your hometown one day, I hope you can make some contributions to it, and it is not because of genetic modification of the brain, locking of the mind, and deletion of memory, making it impossible to think. The evil is not because of these illusory existences that limit yourself.
