Ouyang Xiu believed what Xiang Yu had said. Since Xiang Yu mentioned that Ouyang Ke was about to be finished, it must be true.
What they needed to do now was wait. Currently, Mo Aiguo was waging a fierce political struggle. The main characters in this struggle were actually Mo Aiguo and the Mayor, Zheng Yiguang; everyone else was just cannon fodder.
On the surface, the two appeared to be cordial, but in reality, they were both secretly employing tactics. Mo Aiguo, however, was clearly more successful. For one, he was the attacker and had prepared for all aspects. Furthermore, he had powerful connections from above supporting him.
Even more importantly, he was supported by the evidence provided by Xiang Yu. Whenever he wanted to take action against someone, Xiang Yu would supply the evidence. With irrefutable proof, no matter how clever your methods or how strong your backers, you were doomed.
