A dignified lady (Princess Wanning) in the ancient world passed away and her soul traveled to the body of a modern high school girl, and was bound to the "Powerful Country System" (requiring her to absorb the essence of modern knowledge and feed it back to the original world). But she knows nothing about modern mathematics and physics. The system designated the first-grade god of study (Shen Yu)—an indifferent boy who highly advocates science and puts rationality above all else (who looks exactly like the young master of her rival's powerful family in ancient times)—as her study partner on the grounds that "the energy match is optimal."
