Tan Rou's eyelid twitched, as she thought the princess was truly foolish. Being the King, he would definitely loathe someone threatening him with another person, especially when that person wielded significant power.
Prince Busodi's power might not surpass the King's, but according to Lin Yu's analysis, the King definitely had some vulnerability that Prince Busodi was privy to. If Prince Busodi were to use that vulnerability to threaten the King, the King would likely become even more enraged.
Tan Rou was somewhat worried. She did not want to see internal strife within the royal family of J country just yet, as she and her team had just arrived there. She needed to stay for at least a month, and her teammates might need to stay for over a year. If a conflict erupted within J country, it would definitely affect them.
