Premium incense powder brought from Hong Kong through special channels, stored in an exquisitely crafted porcelain jar inside a rosewood box. It was given by Lin Tingting to Su Jiuyue as a gift for Huo Zhixing. It was secretly mixed with refined Yan Yang Hua (azalea poison), a neurotoxin designed to slowly destroy the central nervous system when combined with Huo Zhixing's anti-bipolar medication.
