It's a veritable black market!
Seeing that Jiang Han's situation was hopeless, Yang Xiao asked the hotel to check on that string of caravan numbers. As expected, the hotel that took money was capable of anything and soon found out that it was a caravan from the Myanmar-Tai Black Triangle, smuggled into the country, with even ties to a cult.
The buyer was in Xiang Ma Town, but the specific identity wasn't revealed in the information provided by the hotel.
In other words, this intelligence was real. It meant either Marquis Zhenbei or the other two families were the buyers for this batch. Hmm...possibly they pooled money to buy it together.
To put it another way, this batch was indeed real and contained good things. These guys also wanted to use this opportunity to get rid of me. It's truly a two-birds-with-one-stone plan.
