Zhang Jinheng has a box that holds a crescent moon dagger. He bought the dagger when he first entered officialdom to investigate a case.
Li Shunyu thought it was just an ordinary weapon box, until one day during Zhang Jinheng's birthday she saw him putting a note in it. She couldn't help but be curious, so she opened it while he was away and saw several notes under the dagger.
The first one: Please, Your Highness, like me.
The second picture: I wish your highness all the best.
The third picture: I wish your highness to be healthy and safe.
…
The last piece of paper was freshly white and had just been put in: May your highness be as beautiful as a blue kite and live a long life.
The eldest princess Li Shunyu wanted a sword that could break through the dark clouds and sweep away the mud in the court, so she attacked Zhang Jinheng. But later she still couldn't bear to let this high-spirited and free-spirited young man get muddy. She hoped that he could still be the most free and uninhibited person in Dajin.
Zhang Jinheng held her hand tightly and told her, Your Highness, I am willing to be a knife in your hand to break through this filthy court for you and kill all those treacherous ministers.
Purpose: To survive for all the people in the world and regain the lost land
