I Am the Only One in the World, the Last Ninja

Scientist Stephen Hawking once warned: "Don't try to contact aliens, otherwise humans may be slaughtered!" I became an alien test subject, but I decided to fight for humanity, in the world I longed for, in Naruto's world. The host beast: "Your race only has a few brains. The actual situation is a little more complicated than you think. I can't explain it to you clearly. Just take it as it is. From today on, we are a community. You lead and I assist. Whatever should be done, it will be done. Every experimental subject is immersed in it." In their respective worlds, it depends on their own choices and achievements. Come on, what kind of world is this? Where are your human computers and books? Find these. My role is to act as a medium and instill a large amount of knowledge into you quickly. Knowledge can change your destiny. Do you understand? Su Chen: "My educational level is low..." This novel and its characters are purely fictitious.
