Arc 4Huang Xiao Joins Poison God Valley
Huang Xiao helps the Third Princess escape a Demonic Path attack, then seeks treatment for a deadly poison and is led to Poison God Valley by his Black Token. He becomes the Valley Master's disciple and begins learning about the valley as Fang Du travels to Green Ox Temple to fetch Huang Xiao's senior brothers.
- Gu Yi and Pan Lang attacked Uncle Yan and the Imperial Guards, but Lü Ling helped Huang Xiao get the Third Princess away from the Demonic Path fighters.
- Huang Xiao was poisoned while driving the carriage, and the Third Princess gave him a Life-Prolonging Pill before they fled on foot and reunited with the surviving guards.
- Uncle Yan identified Huang Xiao's poison as Life-Severing Hour, so the Third Princess sent him to seek a cure at Medicine God Valley and gave him a personal letter.
- Huang Xiao followed a switched trail marker into Poison God Valley's Five Poisons Formation, where Li Yuncong found his Black Token and carried him to the valley elders.
- The Valley Master recognized Huang Xiao's Black Token and Everlasting Spring True Qi, revealed the connection between Green Ox Gate and Poison God Valley, and accepted Huang Xiao as his disciple.
- Huang Xiao settled into Lingyun Court, learned about the valley's cultivation and poison arts, and considered how his altered meridians might let him absorb power more effectively than practitioners of the Power-Devouring Poison Force.
- Fang Du took Huang Xiao to the Cultivation Archive and agreed to bring his three senior brothers to Poison God Valley, while Huang Xiao gave him Godslayer and a letter for them.
- Fang Du arrived at Green Ox Temple, where Jiang Ying identified him as an expert from Poison God Valley and heard that he had come for his three junior brothers.
