When Qiao Yanyu was treated as a trusted aide by the crown prince, he had also learned some things.
At that time, Qiao Yanyu's memory hadn't recovered yet, and his behavior was normal.
The crown prince was also afraid that his strange behavior would arouse Qiao Yanyu's suspicion. Therefore, he still told him some things that his confidant needed to know.
Qiao Yanyu finally understood a lot of the situation.
For example, the lantern outside the door was evidence of the Crown Prince's power.
As long as such lanterns appeared, it meant that this was the Crown Prince's territory.
Other than his trusted aides, no one else would know about this. After all, there was nothing special about it from the outside. It was just an ordinary inn.
In different places, the Crown Prince's power distribution was different.
