Arc 3Nightwatcher Recruitment and Earth Book
Xu Qi'an enlisted the Directorate of Astronomy's help to frame Zhou Li, secured the Xu family's safety, and joined the Nightwatchers. His first investigation uncovered a saltpeter mine, while messages through his jade mirror drew him into an Earth Sect conflict that Wei Yuan moved to intercept.
- Xu Qi'an acquired a jade mirror from an old Daoist and won Fuxiang's attention with a plum-blossom poem under the alias Yang Ling.
- Xu Qi'an learned of Zhou Li's earlier assault on Zhang Yuying and enlisted the Directorate of Astronomy's arcanists to help frame him for her abduction, leading to Zhou Li's exile and Vice Minister Zhou's dismissal.
- Li Yuchun questioned Xu Qi'an about the frame-up, revealed that the interrogation had been a test, and recruited him into the Nightwatchers on the Eldest Princess's recommendation.
- Xu Qi'an earned Wei Yuan's Upper first-class assessment in the aptitude trials and entered the Qi refining realm with Li Yuchun's help.
- Xu Qi'an uncovered a saltpeter mine on Mount Dahuang and helped Song Tingfeng, Zhu Guangxiao, and Lü Qing kill the salamander demon that had attacked the workers.
- Xu Qi'an spent the night with Fuxiang, returned to his family, and received messages through the jade mirror from Number Nine seeking Jinlian.
- Xu Qi'an bound the Earth Book fragment with his blood, received Number Six's warning against Number Nine, and reported the exchange to Wei Yuan.
- Wei Yuan arranged a decoy trade, Yang Yan destroyed the Earth Sect leader's body, and a merit formation around an old Daoist trapped the fleeing Yin Spirit before Xu Qi'an was summoned to Duke Wei.
