Yun chujiu was naturally not trying to trick them. A person without foresight would have immediate worries.
An existence like the palace of hatred was like a sharp sword hanging above one’s head. Although everything was peaceful now and there was a chance that they would attack at any time, it was still better to be prepared.
Yun chujiu was not surprised by the attitude of Emperor Nan Xuan and the other two. After all, the palace of hatred had used the imperial preceptor to control the four kingdoms for so long. Whether it was brainwashing or deterrence, in short, these people did not dare to easily think of going against the palace of hatred, unless they were forced into a desperate situation, they would not be able to put up a fight.
