Science and Magic

My younger brother is planning to write about a scientist from outside the human interstellar era who came to a planet full of magic in one of the galaxies (star systems) in another galaxy (similar to the Milky Way) and started research on the perfect combination of science and magic. Finally, he returned to the Milky Way and used those magical technologies to bring a great leap forward to human civilization. On February 1, 3021 AD, Yang Yuetian, the greatest scientist in human history, was born into the Yang family of a family of genius scientists. No one thought that this thin baby would bring huge changes to human history.
