As the Speaker of the State, you trusted intelligence from non-official channels, led troops into another state, berated the Speaker of the other state, and even surrounded the State Government!
The crime is enormous.
And Qiu Tu... While he wasn't fooled and didn't act on Xue'er, he secretly went after Yan Chen's daughter, Yanyan?
Originally, Old Pang used this dirty trap to drive the wolf to devour the tiger, aiming to restrain Qiu Tu.
Old Pang had presumed a relatively favorable outcome—just Huang Shangzong using his base power in Dongye State to trouble Qiu Tu, making Qiu Tu's policies fail to leave the State Government.
Afterwards, the enraged Qiu Tu would likely leverage his connections in New State, such as Tang Feifei and Liu Xiongyuan, to hinder Huang Shangzong.
In this way, New State and Dongye State, along with Qiu Tu and Huang Shangzong, would inevitably bog each other down, consuming their resources, unable to attend to other affairs.
