Of course, Chen Yao didn't stop her, because he had no right to.
Even though this is the Imperial Palace, even though he and An Xiaomian have the same status, he is currently imprisoned for making mistakes, and both he and Chen Menglu risked sneaking into the palace, violating the King's orders.
If the Old King were awake at this moment, the siblings would be subjected to even harsher punishment.
However, they heard from their informers placed within the palace that after the Old King returned from leaving the palace, something happened. Now everyone in the palace is looking for doctors to treat the Old King, but there hasn't been any progress.
So, Chen Yao and Chen Menglu, who were already worried about An Xiaomian seizing the throne, disregarded everything and rushed into the palace. Fortunately, many guards knew they were the princess and prince and didn't dare to forcibly stop them, allowing them to reach the entrance to the Old King's residence.
