I'm Just a Repeater from Earth

In the parallel world of the Huaxia Art Institute, Jiang Lin, a junior in the composition department, seems to be just a lazy and casual ordinary student. Until one day, he casually played a piece of music in an empty piano room called "Two Springs Reflect the Moon" that no one had ever heard before. The sad music that traveled through time and space shocked others for the first time. Roommate Li Bowen began to realize that something was terribly wrong with this guy who claimed that he was just a "hard-working repeater" - his easy-to-learn harmony connections were as exquisite as lost ancient methods, his orchestration ideas were unconstrained and straight to the soul, and his understanding of music was even more sophisticated than people of this era. Jiang Lin's body is filled with vast memories and endless music from another world called "Earth". In this parallel time and space where cultural and entertainment works seem to be lacking, those melodies that have settled in the soul begin to quietly wake up. A spur-of-the-moment recording attempt, a piece of audio that has quietly become popular, and a door to a wider world is slowly being pushed open. When a "repealer" from another world decides not to hide anymore, what kind of unprecedented impact and baptism will he bring to the world's music scene?
