Zhao Yao didn't take Zheng Qian's words about making him his lord seriously. In his view, Zheng Qian said that in anger after losing a chess game to him.
He's only a six-year-old child, not favored, and without any ministers' support. How could a genius like Zheng Qian choose him as a lord, unless he's out of his mind? Moreover, he's just an ordinary person, so how could he be the lord of a genius?
It seems that his chess win really struck Zheng Qian. Hopefully, Zheng Qian will be more low-key and honest in the future and not cause Zheng Rang and the others any trouble.
If it were him with such a clever yet troublesome younger brother, he would certainly be driven mad. Even if he didn't die from anger, it would surely shorten his lifespan.
He wouldn't have agreed to help if it weren't for Zheng Rang's delicious cooking and pastries.
After leaving Zheng Mansion, Zhao Yao didn't go to the Li Mansion but went straight to his second uncle's home.
