PS: Let's go with two chapters at once.
Xie Zhiyan said that Xiao Moyun is cautious and somewhat crafty, and Su Xin saw him the same way.
Although he had threatened Xiao Moyun, preventing him from making a move against Flying Eagle Gang, it didn't mean Xiao Moyun would let this matter go.
Su Xin was certain, he would exaggerate his threat and relay it to Shangguan Yanqing, instigating Shangguan Yanqing to cause trouble for him.
Of the three, Shangguan Yanqing was the strongest. Regardless of whether Shangguan Yanqing was provoked by Xiao Moyun or not, Su Xin was sure that he would return to Changning Prefecture.
If he defeated Su Xin, he could seize all the Southern Barbarian specialties of Changning Prefecture, using the gains to enlist his followers.
