The Fourth Prince and the Eighth Prince had a tacit understanding: they would both protect Zhao Yao. No matter how much they disliked each other, they would not make a move against one another for the time being, because they were both waiting for Zhao Yao to grow up safely, to come of age, be conferred the title of king, and securely move to his fief, away from the disputes of the capital.
Before Zhao Yao comes of age and goes to his fief, they tacitly protect Zhao Yao in secret.
"Your Highness, can the Eighth Prince really protect the Tenth Prince?" Wei Mian was skeptical of the Eighth Prince.
"He can," said the Fourth Prince, narrowing his eyes slightly as a deep glint flashed in them, "If he cannot protect the tenth brother, then he has no reason to remain in this world."
The Fourth Prince knew well what kind of person the Eighth Prince was, but he turned a blind eye to what he had done over the years because he could protect Zhao Yao.
