Ch. 241Conservation
Li Yuer attended a lesson on mechanical knowledge, then discussed the universe’s conservation laws with the voice in his mind. The voice simplified energy conservation through a coin-trading analogy, teaching him that nothing disappears but only changes form.
- The lecturer found Li Yuer’s notes blank again and dismissed him after urging him to take notes and review the lesson.
- The lecturer reflected on Li Yuer’s unusual habits and his perfect grades as he headed home.
- Li Yuer returned to his dormitory and spoke with the ethereal voice in his mind, exchanging what he had learned for new knowledge.
- The voice explained the Energy Conservation Law, the Momentum Conservation Law, and the Angular Momentum Conservation Law, but Li Yuer could not understand the explanation.
- The voice compared energy to coins that circulate or become inaccessible, explaining to Li Yuer that matter and energy persist by changing forms.
