Sun Wukong and the others greatly defeated the Heavenly Court's Constellations and then returned to the Water Curtain Cave for a lengthy bout of drinking.
Although Yang Jian had been granted a divine position, his relationship with the people of the Heavenly Court was superficial, because the Jade Emperor, lacking compassion, had pinned his mother under Peach Mountain. If it weren't for Yang Jian's great achievement in cultivation, allowing him to split open the mountain to save his mother, he might still be suffering. Therefore, when Wukong and his group killed six beings of the Western Constellations, Yang Jian didn't feel anything unusual; rather, he was slightly worried.
"Brothers, those six were constellations. You've killed them, and I'm afraid they've already reported this to the Jade Emperor! When the Heavenly Court's army pressures us, what should we do?" Yang Jian asked.
