On 3 September, a comet was seen in the skies of Xiangping and was interpreted as an omen of destruction by those in the Liaodong camp. A frightened Gongsun Yuan sent his Chancellor of State Wang Jian () and Imperial Counsellor Liu Fu () to negotiate the terms of surrender, where he promised to present himself bound to Sima Yi once the siege was lifted. Sima Yi, wary of Gongsun Yuan's double-crossing past, executed the two, explaining his actions in a message to Gongsun Yuan that he desired nothing less than an unconditional surrender: "In ancient times, Chu and Zheng were classed as states of equal footing, yet the Earl of Zheng nevertheless met the Prince of Chu with his flesh bare and leading a sheep. I am a superior Ducal Minister of the Son of Heaven, yet Wang Jian and his following wanted me to raise the siege and withdraw my men. Is this proper? These two men were dotards who must have failed to convey your intentions; I have already put them to death (on your behalf). If you still have anything to say, then send a younger man of intelligence and precision."
