Chu Suifeng held back his anger, and so he chose to break with the Imperial Court. Moreover, even as things developed, perhaps even if the Northern Land was willing to compromise, the Imperial Court would not be willing to give Chu Suifeng time to grow.

Since the Prince was willing to fight, then as his wife, she must not drag him down. Lin Ziyin was not willing to bring modern firearms to ancient times because their lethality was too great, and she neither wanted nor wished to witness such a gruesome scene. Therefore, during the previous battle at Border City, she did not design any firearms for Chu Suifeng.
But now things were different, and in a war flanked on two sides, Chu Suifeng might not be able to handle both, and the ambition of the North Country was always far from small. She did not want Chu Suifeng to make the slightest mistake.
