Tong Xi listened to Zhao Yao's words and remained silent for a moment: "Your Highness, you didn't say it like this before?"
"What do you know, it's called a precaution."
"A precaution?" Tong Xi didn't understand and asked with a puzzled look, "Your Highness, I don't understand what you mean."
Zhao Yao first raised his index finger and said: "First, the fourth brother secretly cultivates his own influence, so that when he comes of age and goes to his fiefdom, he will be fully prepared."
"Oh, I see." Tong Xi asked, "What's the second reason?"
Zhao Yao raised two fingers and continued: "The second is for precaution. If at that time, the Crown Prince loses to Prince Dai, then the fourth brother must formally strive for that position. By then, once he has a certain strength, he will have the confidence to compete with Prince Dai and the third brother."
Hearing this, Tong Xi finally understood, and with a look of realization, said, "So that's how it is."
