Crown Princess, the Crown Prince Rebelled

When I opened my eyes, I was dressed as a princess. The system said: "As long as the prince successfully ascends the throne, you will be able to grace the world." I looked at the prince who was plotting rebellion in front of me, and silently took out the late emperor's edict. The next day, the whole capital heard that—— The Crown Princess and the Imperial Guard surrounded the East Palace, and the Crown Prince was tied into a rice dumpling and knelt in front of the palace. And I held the jade seal and sighed: "I just want to be the Queen Mother, who told you to work overtime in advance?"
