This was an arrow that Jing Yi had made for Su Xiaoxiao. It was especially used to deal with experts, making it impossible to guard against.
The disadvantage was that it could only be used once. The other party would not be easily tricked the second time.
Xu Qing also flashed behind the pillar.
"Are you alright?" the Gu Master asked worriedly.
Xu Qing calmed his chaotic internal breath. "I was drugged."
The Gu Master couldn't help but complain, "Who puts knockout drugs in arrows these days… What a cunning guy…"
Then, his gaze landed on the arrow that had pierced deeply into the wall. His expression was complicated. "Archers of the Imperial Court? The Wei family? No, it's the Leng family's now. Were you followed today?"
"I shook him off," Xu Qing confirmed.
The Gu Master could not help but sneer. "Then tell me, where did this archer come from?"
Xu Qing said, "Maybe he followed you here."
