"Thank you so much, elder brother..." After expressing his gratitude to Ning Cheng with a cupped fist salute, the young man hurriedly walked into a merchant building not far away, without waiting for Ning Cheng to respond.
Seeing the name of the merchant building, Ning Cheng knew he might have gotten himself into trouble. This was the very Exploring Mirage Merchant House that the Yuansoul cultivator had mentioned before—the young man, with his injuries not yet healed, hastily entered the merchant building most likely to sell the Mirage Stone he was holding.
Considering the wound on the youth's back, he must have been attacked because of the Mirage Stone. The youth probably realized he couldn't keep the Mirage Stone safe, so he decided it was best to sell it quickly.
