A messenger from the State of Chen came to report that the former ruler of Chen had died and Prince Liu had succeeded him. Prince Sheng of Chen and Gongsun Wu, the son of Crown Prince Yanshi, then reported that Prince Guo and Sima Zhao had secretly plotted to assassinate Crown Prince Yanshi and enthrone Prince Liu. King Ling of Chu immediately sent troops to attack Prince Guo. Sima Zhao killed Prince Guo and presented the State of Chen to the State of Chu to seek wealth and glory. In the end, Sima Zhao was exiled to the East Sea, paying the price for his treachery. This story tells us that treachery is a shameful act that will ultimately be punished.
