My Debt Is to All the Worlds

Don't inherit an inheritance, you will become unhappy. Especially the "liability of causality" that inherits an entire universe. When I woke up in the cemetery of the gods, a cube claiming to be "Shou" told me that if I want to survive, I must enter thousands of worlds and work for them. Behind me is the "conceptual disaster" chasing me; in front of me is the 24-hour countdown to death. And my first mission is to return to the most familiar doomsday to protect the girl I want to forget the most and can't let go of. I am Gu Yuan, an observer staring into the abyss.
