I'm on the Technology Tree in Naruto

What should I do if I'm a cannon fodder genin who traveled through the world of Naruto? Lin Xiao: No hurry, let me see the technological level of this world first—— Ninjas used carrier pigeons to send messages? Come on, come on, I'll teach you how to make a telegram. Ninjas walk and run? Come on, come on, I'll build you a car. Do ninjas fight on the basis of human lives? Come on, come on, I'll make you a cannon. What? You say ninjas don't need these? It doesn't matter, Cloud Hidden Village next door is very interested. What? Is the Akatsuki organization coming to cause trouble? Mr. Kakuzu, this is a contract. The annual salary is five insurances and one housing fund. You are responsible for security work. Think about it? What? Kaguya Otsutsuki wants to destroy the world? Uh... This is a bit troublesome. But it doesn't matter, I just used her ashes to deduce the mass-energy equation. Kaguya, have you ever heard of nuclear fusion?
