Akira Jinguji, a Ph. D. In Physics, traveled to a ninja world after a collider experiment accident and became a low-achiever with the lowest grades in the ninja school. In this world, people revere Chakra and regard it as an extraordinary energy given by God. But Jingujiaki was shocked to find that the nature of the so-called chakra could be completely explained by the laws of physics that he was familiar with! Energy conservation, electromagnetic induction, fluid mechanics... While others were still meditating on the "mind's eye" and feeling the "natural energy", Akira Jinguji had already begun to calculate the best parabola for the shuriken, use the resonance frequency to crack the illusion, and optimize the energy conversion efficiency of the fire escape through the second law of thermodynamics. A "student" ninja who used scientific formulas to analyze ninjutsu was born. He will use his own way to subvert the common sense of the world and create an unprecedented scientific way of tolerance.
