I open a history tutorial class in Daming

After traveling through the Ming Dynasty and falling and blinding himself, Song Shen learned that he would die three years later because of the Hu Weiyong case.
Fortunately, there is an imperial teacher system connected to it. As long as the emperors and generals of past dynasties who are simulated in the system can pass the exams, then my eyes can be cured and my destiny can be changed!
But after class, Song Shen discovered a problem.
Why doesn’t history books mention that Zhu Yuanzhang’s mouth was so annoying?
"Oh, Emperor Qin Shi Huang, you just didn't teach your child well, otherwise why would Prince Fusu commit suicide?"
"Tell Li Shimin, Emperor Taizong of Tang, you can't be so harsh. Look, if you push him too far, your son may like a boy, right?"
Seeing that a fight was about to break out, Song Shen said: "I will teach you these things. Zhu Yuanzhang, shut up. You are the noisiest person in the class!"
Zhu Yuanzhang kept his mouth shut, but Song Shen felt that something was getting increasingly wrong.
Ying Zheng: "Thank you for your teachings, sir. My Great Qin warriors have defeated that damn Macedonian phalanx. The territory of Great Qin has expanded several times. Finally, I don't have to worry about the remaining princes having nowhere to stay!"
Liu Che: "Sir, hey, Qubing has passed the threshold of twenty-four. I can finally let him conquer the world!"
Li Shimin: "I have made the girl from the Wu family a female official. I have to say, she is really smart!"
Song Shen looked at Zhu Yuanzhang silently.
Zhu Yuanzhang grinned and said, "Sir, now that things have come to this, I will tell you the truth. The Ming Dynasty has already reached the American continent you mentioned!"
