"Time Travel: The Resonance between Singers and Ninjutsu" is a time-travel fantasy adventure novel based on the theme of Naruto. The protagonist is JJ Lin, a singer from the real world. He traveled from the backstage of a concert to the world of Naruto's Konoha Village. He initially had no chakra and was suspected of being a spy by Naruto and others because of the microphone he was wearing and carrying. Later, he used his singing to resolve the crisis. This novel is based on Naruto's original worldview and adds the setting that "singing can stimulate 'sound energy' and resonate with chakra." JJ Lin can use singing to appease tailed beasts, shatter low-level ninjutsu, and assist in refining chakra, forming a unique singer's fighting style. The main storyline revolves around him entering a ninja school to study, developing "sound energy ninjutsu", participating in various tasks and chunin exams, and getting involved in the Konoha collapse plan. In the process, he will use his voice to break the war situation and explore the truth of time travel. The overall highlight is the innovative "singing + ninjutsu" ability system, which combines Naruto's classic plot and the protagonist's singer identity to show the growth and bond of an outsider in the ninja world.
