Shen Yifei, a doctor of modern physics, opened his eyes and became a poor scholar in Shaoxing in the Southern Song Dynasty for eleven years. He was a poor man and didn't even have a pair of complete shoes. He had just been expelled from the county school and his path to the imperial examination was blocked. He even had a hole punched in the back of his head. What's even more confusing is that he found that he had traveled to the eve of Yue Fei's murder.
Others travel through time and make inventions, but he can't even burn glass. But the doctor has a doctor's method - don't make guns or cannons. He decided to use knowledge to "reduce dimensionality and attack" this era. The laws of physics, mathematical modeling, and future predictions were all transformed into spectacular operations that would lead to promotion and fortune, and stir up troubles.
Starting from a bowl of brown rice, it changed the direction of the entire Song Dynasty. While Qin Hui was still making "unnecessary" calculations, Shen Yifei had already laid out a big game. Let's see how a doctor of science uses formulas to break the situation and perform dimensionality reduction attacks in ancient times!
