Dust Genesis

The universe was not born from the Big Bang, but from the deathly dream of an indescribable "primordial god". When you wake up from the dream, everything will return to nothingness. Lu Chen is a "wake cell" in the original god's dream, and he realizes that he will eventually die with the dream. His only way to resist is to create a civilization that is real and large enough in the dream, and use the "weight of existence" of all living beings to "press" this dream into reality, thereby making the dream eternal.
