The Music Demon of Ten Thousand Worlds

Other people play the piano to make music. He plays it to kill for money. After inheriting the legacy of a giant-slaying assassin from the Divine Realm, Leng Jian embarks on a path of assassination. Starting from Earth, he travels to the Milky Way, the Andromeda Galaxy, this universe, the Divine Realm’s universe, the many god-tier universes of the Great Desert, the universe clusters, and this world... Unlike ordinary people, Leng Jian doesn’t start a business to make money. He roams the primordial myriad realms with nothing but a magic zither.
