Shi Changan (the eldest daughter of the sect) × Zhao Tanxiang (the royal lady) × Qi Yuntang (the chivalrous girl)
The protagonist group turns against each other? Corrupt government? Troubled times?
(It's very good! And no brains! Be careful! Please forgive me if it's not well written!)
Purpose: Cherish the people in front of you, and if you have a "chivalrous heart", you might as well go for it
