Seventh Rhythm

Lin Qianyao never thought that the turning point in his life would be a contract, a cigarette can, and a man named Zhaoyu. From that day on, he was no longer human. Some are chasing him, some are protecting him, some want to take something from him, and some want to give him something. On the verge of death, he signed a contract of unknown origin, in exchange for "a part of his life" in exchange for a key and a chance to start over. From then on, he was involved in a world of immortals, contracts and power struggles. Utopia, the Holy See of Dawn, the Immortal Alliance - all parties are looking for him. Some say he is a key, some say he is a container, some say he should not be alive at all. And he just wants to pay off this month's loan first.
