I, the Best in the World, Don't Know Martial Arts

As a scientist, time travel is not scientific in itself. Well, I am still the best in the world. The problem is that I don't know martial arts. Martial arts is not scientific in itself. How can I use that thing? This is a story about Newton being sad when he saw it, and Einstein crying when he heard it. It all starts with the sparks and lightning along the way. I heard that the introduction should be a hundred words long. Well, that's enough for now. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
