Cao Chong is Cao Cao's favorite son and the cleverest of all sons. When he was five or six years old, there was a famous story about "Cao Chong as an elephant", so his intelligence has always been praised by everyone. Cao Cao regarded him as an heir in training, but unfortunately he was jealous of talents. Cao Chong died at the age of thirteen, leaving only endless thoughts for Cao Cao.

Contemporary prodigy, and Zhou Buyi, two prodigies of similar age, played together since childhood, with outstanding intelligence and similar language, so they established a profound friendship. Cao Cao is also very happy and appreciates Zhou Buyi. It is also considered that after Cao Chong inherits in the future, he will be assisted by people around him.

However, Cao Chong died young, and after Cao Chong's death, Cao Cao's attitude towards Zhou Lve changed greatly, because his intelligence made him feel threatened, fearing that no one in Cao Shi's descendants could hold him down. Cao Cao cherished talents, but considering that Cao Pi's talents could not suppress him or threaten Cao Zhi's interests, he secretly assassinated him.

Zhou Buyi is very clever. He showed military genius at an early age. Cao Cao attacked Liucheng for a long time, and his ministers were at a loss. When he was young, Zhou Buyi actually contributed ten tricks to Cao Cao and successfully helped Cao Jun win a great victory. On the surface, Cao Cao praised Zhou Buyi, but in his heart he was afraid that he could not control it. Moreover, the relationship between Zhou Buyi and Liu Bei is not simple, and he is even more afraid that his obsession with Liu Bei will pose a great threat to Cao Shi.

Of course, after Cao Chong's death, Cao Cao would think of his son Cao Chong when he saw Zhou Buyi. Cao Cao also wanted to die for Cao Chong, but he was more afraid of his potential threat.
