Plot
Thousands of years ago, the evil Princess Jingjue cast the cruel Ghost Eye Curse upon her own people to subjugate them. The curse will kill whomever is afflicted when they turn 40. Crueler still was that the curse will be passed down from one generation to the next. The only way to lift the curse is to retrieve and bring together the Dragon Bone Celestial Tome and the Mu Chen Orb. The former had been retrieved in a previous adventure but the Mu Chen Orb is still to be found.

After translating most of the ancient text on the Dragon Bone Celestial Tome, Hu Bayi and Professor Sun determine that the Mu Chen Orb is located in Emperor Xian's Tomb in the ancient Longfeng Mountains in the Yunnan Province. Bayi, Professor Sun and Shirley Yang visit Chen Yukou for the translation of the last sentence of the Dragon Bone Celestial Tome. But Chen is half-mad and half-consumed by regret and offers them little help aside from warning them to "never look into its eyes."

Bayi, Shirley, Professor Sun, Zhou Linglong, Wang Kaixuan (nicknamed Fatty) and Jin Ya (nicknamed Gold Tooth) travel to the Yunnan province. On the way, they encounter in a landslide the Chongshu, a form of witchcraft where in a person is infested with deadly insects and is encased in stone. They meet up with Cai Yun, who manages a small, remote hotel, and her daughter Kong Que.

That night, the group watches the Flameflies outside the hotel and Kong Que shows them the Flamefly Queen which she has caught in a glass jar. Kong Que tells them that Flameflies are blind and will follow the smell of the Queen loyally. However the jar hides her scent. Furthermore, the insects will burst into flames when they die and will follow the Queen to her death. Fatty takes the jar of the Flamefly Queen from Kong Que.
