The moment he saw the empty bottle, Master Sang knew that he had been tricked.
Why did he say that he had been tricked and not misunderstood them? This was because there was clearly the aura of a Yin Gu in this jade bottle, which proved that the Yin Gu had indeed been in the bottle not long ago and its aura had not dispersed in time.
It was precisely because of this that they could deceive him and the experts of the Sang family.
This girl pretended to pester him, looking extremely guilty. She lured him to snatch it, but in the end, he only snatched an empty bottle. He knew that he had fallen into her trap without guessing. When he was hit by this girl's diversion, he was almost certain that while everyone was entangled here, the Yin Gu had been sent to a safe place.
It might even be in the hands of that Ancestor Sikong. At the moment, he did not have the guts to kill his way up the Nether Mountain to snatch something from that Ancestor.
