AI tell me that humans already have a unified theory for electromagnetism, weak force, and strong force. I want to read these theories.

I'm almost done with the first volume of Feynman's Physics Lectures. I think it's really great. I plan to finish reading the remaining two volumes (though I don't know what the content of the remaining two volumes is). At the same time, the AI suggests that I read Griffiths' Introduction to Quantum Mechanics, Introduction to Electrodynamics, and Introduction to Elementary Particles. After reading these, move on to read the books on gauge field theory.

I looked up Griffiths' book and found that it has a Chinese version (my English is not good). However, the price is high, and AI sometimes makes mistakes, so， I want to know that the plan is appropriate?

Besides, I know PDEs and Riemannian geometry. But about group ring field, I only know the basic concepts.
