Qin Zong heng's forces attacked Yang Xingmi in Yangzhou, but they were unable to capture it for a long time. The Liang army ferociously attacked Qin Zongquan. Qin Zongquan summoned Sun Ru and others back many times, but Sun Ru was reluctant to come back. Qin Zong heng repeatedly urged him to, and Sun Ru became angry and killed Qin Zong heng. He personally led his troops to capture Gaoyou and thus expelled Yang Xingmi.
