I'm a Student, so It Makes Sense to Build a Gundam, Right?

Su Chen traveled through time and space to an alien planet with advanced civilization. In just a few years, with his rare scientific talent, he became the most admired chief scientist on the entire alien planet! Unexpectedly, an experimental accident would allow him to travel back to the earth and return to his original home. Su Chen was only eighteen years old at this time and still a student. His father happened to be a scientist and took him to visit a scientific research institute. Su Chen accidentally showed his hand, and then he got out of control. Lithography machine? This is the quantum chip ball of an advanced civilization. Have you seen it? Nuclear fusion? I directly build a Dyson sphere so that the energy of the entire sun can be used by the country! Exoskeleton armor? It's too troublesome, and it's not practical, so I might as well make a Gundam by hand! Until one day, the alien fleet came to the earth, created the biggest scene in the universe, and respectfully wanted to invite Su Chen to return to the K78 planet. Foreign scientists were confused when they saw this. It turns out that our opponent Su Chen has always been the chief scientist of a higher civilization?
