Su Chen became a tutor in Prince Yan's Mansion, and his slogan was: Don't fight, don't grab, and don't take the lead.
He taught Zhu Di how to perfectly avoid Lao Zhu's minefields and how to be a transparent vassal king.
But Su Chen didn't know that all the "forbearance strategies" he taught Zhu Di were heard by Zhu Yuanzhang and Zhu Biao.
Zhu Yuanzhang: Good boy, teach our son to 'use retreat to advance'? This theory of national policy is simply amazing!
Zhu Biao: My fourth brother is too sensible. Why do you tolerate this so much so as not to embarrass me? He must be the emperor!
Then, the most outrageous scene in history occurred.
Zhu Di is desperately refusing to establish the throne, and Lao Zhu is desperately collecting evidence of Zhu Di's excellence.
Zhu Di: "Sir, I obviously did as you asked, so why do they look at me with more and more admiration?"
Su Chen: ... Maybe, this is the real emperor through the ages.
