When the North Prince appeared, the princess from the previous wasn't feeling despair.
Although the North Prince would take the treasure away if she became his hostage, she might still be able to cooperate with the North Prince.
However, after Prince Yi appeared and became a hunter, she couldn't help but feel despair.
She knew that the emperor would not let go of the remnants of the previous dynasty. If Prince Yi won, it meant that she and her people were finished.
Previously, they had entered by turning off the mechanism, according to the map. Only she knew that the mechanism could be reactivated.
She would not have a good ending if she was caught by Prince Yi. It was better to let the emperor's most precious brother be buried with her.
At that time, they could watch if there was any estrangement between the emperor and the empress dowager.
Furthermore, if Prince Jin were to die here, the northern border would definitely be in chaos.
