In Tianbei City, the only people who could still have a trace of Xiao Yi Xian's Dou Qi in their bodies were those who had gone to her clinic for treatment. After all, no one in Tianbei City could threaten Xiao Yi Xian.
Xiao Yan silently followed the two Hong Family members. The Hong Family had brought along someone Xiao Yi Xian had cured, and Xiao Yan instinctively felt that this was not so simple.
Moreover, in that brief instant, Xiao Yan had detected with his soul power that the person in the middle was already dead.
The two Hong Family members dragged the man into a secluded corner of the market. After furtively scanning their surroundings and confirming that no one had noticed them, they tossed the corpse aside, arranging it to look as though the man had sat down against the side before dying. Then they left at once.
Clearly, the two did not want their identities exposed, so they wore no badges representing the Hong Family.
After they left, Xiao Yan came over to the corpse. With his current strength, avoiding the notice of two Dou Lings was far too easy. Using his soul power to inspect it, Xiao Yan discovered that the corpse's internal injuries had originally been completely healed by Xiao Yi Xian's Dou Qi. However, Xiao Yi Xian had begun as a poison master whose foundation was the Woeful Poison Body, so some poison techniques had inevitably been used during the treatment.
Once one reached a certain realm, poison arts could save lives, while medical arts could kill. It was merely a matter of how they were used.
After examining the corpse, Xiao Yan discovered that the man had been poisoned to death! The poison used was quite potent, nearly taking his life instantly.
