The Crown Prince was originally the legitimate heir, he didn't need to fight or scramble; as long as he sat steadily on the Crown Prince's throne, the imperial throne was his.
But perhaps he had held the position of Crown Prince for too long, he always felt that until the final moment, nothing could be concluded. Perhaps as a child, the struggle for succession during the late Emperor's reign stimulated him, resulting in his suspicious and doubting nature.
"Since he has allied with Prince An, this battle is inevitable." Su Yu was not interested in those roundabout matters. From the moment Han Jing proposed to support Su Xingqiao's succession, he had already thought about it. Given the current situation, no matter who the Emperor chooses, a bloody conflict is unavoidable.
So now, on one hand, it's about convincing the Emperor to gain support in the court, and on the other hand, it's about preparing for battle.
