Yunnan is located on the southwestern border, at the frontier. It can be said that many of the drug traffickers in the country are mostly gathered in this area, and many sources of goods also enter the country directly from abroad via Yunnan.
In such a place, many local forces are extremely terrifying, even those above dare not interfere too much in these matters.
Besides Yunnan, Miao Territory also exists in places like Guizhou; Gu originated earliest from Guizhou. Liu Hun didn't quite understand why Niu Ben would take them to Yunnan.
When Liu Hun left Mr. Chen, the old man gave him an empty bullet. The current ******** in Yunnan was once one of Mr. Chen's old subordinates.
Thus, Mr. Chen told Liu Hun that if there was anything happening later in Yunnan, he could find that person for help.
Faced with Mr. Chen's kindness, Liu Hun kept it all in mind. Even when leaving, he didn't say thanks, because both understood that a simple thanks couldn't express it all.
