It Should Be Reasonable for a Dignified Nuclear Physicist to Practice Cultivation, Right?

Controlled nuclear fusion? Microreactor? Sorry, that's fine with me. As long as the materials are good enough, I can make it. Wait, how did I travel through time and cultivate? Flying sword? What are these? But isn't the so-called cultivation just the iteration of energy? I'm good at this. Kung Fu? I created my own nuclear fission technique. Martial arts? Look at my hydrogen bomb punch. Swordsmanship? Please call me the Nuclear Explosive Sword Fairy. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
