Stardust Repairman

In the late interstellar colonial era, humans and 29 other alien races explore the universe together, but hidden under the surface of peace is a thousand-year struggle for the "source code of the universe" - a mysterious program that can restart or end everything. In a garbage dump at the end of the universe, a maintenance technician discovers that his wrench can awaken ancient civilizations. Now, the whole galaxy wants to kill him and seize the treasure, but he just wants to repair his father's spaceship and ask, "Why did you abandon me back then?"
