Using Science to Analyze the Ninja World

A doctor of materials science who has never watched Naruto traveled to Konoha Village at the end of World War II. While others were still practicing ninjutsu and fighting with chakra, he silently took out the experiment report: "The essence of chakra is the transformation of biological energy. Ninjutsu is just an energy release program with a specific frequency. Blood inheritance limit? Genetic chain technology." So—— Medical ninjutsu? Learn about nano-repair technology. Tailed beast? High-energy biological weapons deserve study rather than awe. Sharingan? Genetic engineering can theoretically be replicated. The Third Hokage: "This guy said that Konoha is like a pyramid scheme, but why do I think he is right?" Tsunade: "He changed my medical ninjutsu to 'biological regeneration technology'... And the effect is even better." Orochimaru: "Like-minded people! Should we do human experiments together?" Protagonist: "No, I only do scientific experiments. Also, don't steal my samples." Starting from a small researcher in Konoha, he gradually established a scientific research empire, and finally transformed the ninja world into a scientific and technological civilization. By the way, I have included all the tsundere female ninjas from all over the world. This is the story of a time traveler who only believes in science and conquers everything in the ninja world.
