In 2025, AI music enthusiast Lu Xun—stuck in obscurity for his outdated style—dies from an all-nighter and wakes up in the Myriad Worlds Reincarnation City. Because transmigrators abused Earth's entertainment works, parallel-world culture has collapsed, and the Myriad Worlds Alliance Tribunal has imposed a Thought Stamp: plagiarism is strictly forbidden, and violators face total soul annihilation. Reborn in the year 2000 as a college freshman, Lu Xun has lost his memory of Earth's hit songs and carries only an AI music system. Jay Chou, JJ Lin, and David Tao have yet to debut, and Chinese pop is on the eve of a gathering storm of rivals. With the AI system assisting his original creations, Lu Xun only wants to live easy—but unexpectedly bursts onto the scene with a futuristic retro style.
