In the end, under Huang Feihu's various stubborn and unyielding demands, Jiang Ziya had no choice but to promise numerous concessions and draft written agreements before he could persuade Huang Feihu to take action.
Although Huang Feihu continued to participate half-heartedly, the combined military forces created an imposing momentum that made Chong Shun too afraid to resist.
However, while this was the case, a superficial display of resistance was still necessary, and Huang Feihu refrained from taking any action, merely observing from behind.
After all, his agreement with Jiang Ziya stipulated that he would only intervene if West Qi showed signs of defeat.
As it turned out, Huang Feihu's intervention wasn't even needed. Under Ji Chang's army, Chong Shun put up only minor resistance before abandoning the city and fleeing.
Unfortunately for Chong Shun, luck wasn't on his side; he was ultimately captured again. Jiang Ziya naturally wouldn't spare him and had him executed publicly.
