公孫淵
On September 3, 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 and "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." When Gongsun Yuan sent Wei Yan () for another round of talks, this time requesting he be allowed to send a hostage to the Wei court, Sima Yi dismissed the final messenger as a waste of time: "Now that you are not willing to come bound, you are determined to have death; there is no need of sending any hostage." Apparently, Sima Yi's previous suggestion of further negotiations was nothing more than an act of malice that gave false hope to Gongsun Yuan while prolonging the siege and placing further strain on the supplies within the city.
