But there is no way for him to rely on this strongest luthier system to return to the original world. But there was one thing he didn't quite understand. Even though he was the "strongest", he wasn't that strong as a violinist? Use the sound of the piano to influence the world? In a world full of war and death, would anyone listen to the music of the piano? If a child understands this truth, will the system not know it? Isn't there a bug in this strongest luthier system?
