Using the assassination of the envoy group and the kidnapping of Princess Xi as a pretext to capture the Royalist faction.
Princess Xi doesn't want things to escalate, and eventually, she will have to come to Qiu Tu for help.
Qiu Tu can still hold some leverage over Princess Xi.
So.... how many divine calculations are there in this world? It's just about being prepared enough and having enough contingency plans.
As for what to do if the Kou family or Princess Xi doesn't give face after Rain Butterfly arrives?
Not to mention that both factions' current core demand is to "maintain surface peace," just speaking of Qiu Tu's rising reputation, there are few in the entire Northwestern Region who would dare not to give face!
Others don't know, Zhao Ji's attitude toward Qiu Tu is not very friendly. They've only seen Zhao Ji's close and multiple cooperative relationship with Qiu Tu.
So, Qiu Tu now gets the most benefit from pulling the tiger's skin.
