Lin Jian, a talented former band guitarist, raised his daughter Wanxing alone, who was aphasic due to psychological trauma, after his wife Chu Yin passed away unexpectedly. The heavy pressure of reality caused him to seal up his music and dreams and become an ordinary picture book restorer. When all treatment methods failed, Lin Jian accidentally discovered a mysterious set of deeply immersive virtual reality equipment left by his wife - "Xumi Realm".
This is a miraculous world based on emotion and memory, which can transform "music" into the physical power that creates all things. In order to awaken his daughter's dusty soul, Lin Jian took Wanxing into the Sumeru realm and strummed the strings again with his rusty fingertips. What he plays is no longer the frivolous rock music of youth, but the lullaby of life that can make flowers bloom in desolate places and ripple the sea of silence.
Here, he met two "hers": one is the AI "Ling" created by his wife based on himself as a world leader. She possesses Chu Yin's wisdom and memory, but is a brand-new existence; the other is "Ni", a top musician in the real world who has long been a god and entered the Sumeru realm to explore the origin of music. She is deeply attracted by Lin Jian's simple but creative music.
A depressed dad, a mute daughter, an AI "phantom" of his deceased wife, and a real-world music queen. When his dusty talents are rekindled in the virtual world, and when the music of healing resounds across the stars, Lin Jian not only has to face the threat from a huge organization that covets this technology, but also has to make a difficult choice between his past memories with "Ling" and his future resonance with "Ni".
