I came from planet D and traveled through time and space with the waste system into a completely unfamiliar time and space. Unfortunately, I am not the protagonist.
I got to know Hongyu, the demon king of time and space.
Me: "How do I return to the real world?"
Kureha: "You can go back after completing the main storyline in the book."
Me: "But if I die in the book, I will die in reality too."
Hong Yu: "It's okay. As long as I'm here, you won't die."
I held Hong Yu's body and watched this time and space collapse. Planet D, farewell forever.
