When Ye Han arrived at Yongze County, he not only brought the imperial edict from His Majesty, but also a letter for Su Pan'er from Fei'er.
In the letter, Fei'er explained in detail his feelings of longing for Su Pan'er.
He also recounted in detail how he and Ye Han ended up in Luoyan Village.
It turned out that the Emperor had gone to a royal villa for a spring outing with his favored Imperial Consort Hua, with Fei'er, the Eighth Prince, accompanying his mother. On the return journey, His Majesty was attacked.
Ye Han happened to be there. In the ensuing confusion, he defended the Eighth Prince, and in the process of escaping from the assassins, they were separated from the group.
As they were fleeing and hiding, Ye Han realized that these so-called assassins were not targeting His Majesty, but the Eighth Prince he was protecting. Their real goal was to take the Eighth Prince's life.
