The world war against the Tang Empire began with a plot in Chengjing City of the Yan Kingdom. But the real turning point was in Qinghe County, where the rebellion by the warlords led to the demise of the Tang navy, and the Great Lake was dyed red with blood. After that, the West-Hill Divine Palace Coalition Army invaded the north. The Southern Army did not arrive in time to help, and if not for the Academy's disciples guarding the Verdant Canyon, even though they suffered serious injuries and even lost an arm, the Tang Empire might have really been destroyed.
This was the first rebellion in the Tang Empire since its founding. And according to the news that spread after the incident, the scene was extremely gory. That was why compared to the powerful West-Hill Divine Palace and the Golden Palace, the Tang Army was more enraged against the warlords of Qinghe County.
