Historical Information
Xu Si was an officer of Zhang Miao the prefect of Chenliu. When Zhang Miao chose to betray Cao Cao and join Lu Bu, Xu Si followed. Xu Si remained loyal to Lu Bu and joined him in his flight for protection under Liu Bei. For his service, Xu Si was appointed gentle of the general staff by Lu Bu during Lu Bu's rebellion against Liu Bei. When Cao Cao and Liu Bei joined forces to drive Lu Bu out of Xaipi, Xu Si and Wang Kai were sent to Yuan Shu to renew talks of a potential alliance. While these negotiations were still ongoing, Lu Bu was defeated and killed. Xu Si chose to flee from Cao Cao, taking up service with Liu Biao.

It was while in this service that Xu Si would find himself working alongside Liu Bei, who had also joined Liu Biao. At one time, the three discussed the heroes of their time and the character of Chen Deng came under scrutiny. Xu Si insisted that Chen Deng was arrogant and rude, offering as evidence that he had once been made to stay in a small bedroom while guest to Chen Deng, while Deng continued to use his large and lavished bedroom. Liu Bei took offence to this accusation, as he had known Chen Deng quite well. He claimed Deng treated Xu Si so for being a useless philosopher who'd done nothing to quell the chaos of the land. Liu Bei even went on to claim he wouldn't "mistreated" Xu Si even further by not wasting even a small bedroom on someone so "worthless".

Romance of the Three Kingdoms
Xu Si only appears in Chapter 19 of the novel, during the siege of Xaipi. He proposes seeking aid from Yuan Shu to break Cao Cao and Liu Bei's siege. Both he and Wang Kai are sent by Lu Bu and they manage to break the siege to seek aid from Yuan Shu. The warlord refuses to just send aid due to former poor negotiations with Lu Bu and demands that Lu Bu provide his daughter to Yuan Shu's court before he will send soldiers to relieve the siege. Xu Si and Wang Kai manage to bring back this news, but at the cost of their military escort, He Meng. Recognizing He Meng will give up their plan, Xu Si recommends a strong military force to try and break through the surely tightened guards on the Southern Roads. When Lu Bu wants to launch the attempt immediately, Xu Si convinces him to wait a day, as the next day was a "lucky day". The attempt fails and Xu Si disappears with the death of his lord.
