Li Xuan was leaving the Forbidden City, holding the reward bestowed upon him by the Jingtai Emperor.
Since Li Xuan had previously submitted his terms, the Emperor's reward was more of an honorific nature.
It consisted of a bright yellow Feiyu Suit, the merit status of the 4th-rank official of Shangqi Duwei, and a Xiuchun Knife with a vermillion scabbard—worth mentioning is that this is not truly a knife, but rather a tiny, disk-shaped magical instrument, less than an inch in diameter. When attached to any knife handle, it would alter the appearance to that of the Xiuchun Knife. The effect is akin to the 'skin' of video game characters and equipment; a different skin changes the appearance.
In the Great Jin Dynasty, this was an important honor, equivalent to the ancient Qianniu Knife, which could only be worn by the emperors' close confidants, high-ranking ministers, Xiuyiwei, and top officials of the inner Jishi Bureau.
