For the Yan Kingdom, with the Zhou army pressing its borders and the main forces of the Yan army trapped in Xiliang, the Yan Kingdom cannot simply hand over their Empress Dowager of Yan to appease the Zhou's anger. Otherwise, Emperor Yan, Murong Li, would be drowned in the spit of the people!
After all, the desire of Zhou to annex the world is well-known, and this is yet another great opportunity for Zhou to destroy Yan, which they certainly won't miss.
Only if Murong Li propagates the idea of resolving the two countries' fate through national policy, merging the two into one country to avoid the people suffering from war, could he force the Eldest Young Lady to be wary of public opinion and compel her to agree, thus winning a slim chance of survival for the Yan Kingdom.
However, when did Murong Li send Wang Hanbing as an envoy to Zhou? She had received no news whatsoever.
