In the future world, an alien spiritual body called "Nightmare" quietly invades, eroding the host's mind by polluting human dreams. Figure prototype artist Ryuse Natsu closed his heart due to childhood trauma, but was parasitized by the top nightmare "Void Seed" in an accident. At a critical moment, the "spiritual purification system" that maintains the order of the dream was forcibly bound to her. The system is venomous and arrogant, but is forced to cooperate with Lingze Xia to fight against dream pollution. In order to survive, Lingze Xia must enter the chaotic dreams of others and perform purification tasks. During this period, she reunited with Lu Yeci, the current chief dream monitor, who had been missing for many years. Lu Yesi intervened forcefully in her life and "mission", and the two fought side by side in a dangerous dream, and their emotions continued to heat up. Under the systematic hell-like training and Lu Yesi's overbearing protection, Ling Laixia gradually uncovered the truth about the nightmare invasion, her family's conspiracy, and the fateful entanglement with Lu Yesi, and finally awakened as the strongest dream master, completely purifying the sources of spiritual pollution that threaten the world.
