Guo Jia can be said to be a god in the first half of the Romance of the Three Kingdoms, and he is Cao Cao's favorite strategist, who advises Cao Cao and makes a lot of merits!
If Guo Jia does not die, there will be no Three Kingdoms, and the original saying is like this: Guo Jia does not die, and if the Dragon does not come out, there will be no Three Kingdoms! In the Romance of the Three Kingdoms, everyone knows that Guo Jia helped Cao Cao to defeat, Liu Bei, Lü Bu, Yuan Shao, the Northern Expedition to Wuheng, and half of the Han Dynasty's territory was Cao Cao's, all of which were obtained under the condition that Guo Jia gave advice! Heaven is jealous of talent, Guo Jia died when he was not very old! Cao Cao sighed! Posthumously awarded the title of Marquis of Liuyang Pavilion.
There are two theories about Guo Jia's death, one is: during the Northern Expedition to Wuheng, because of the harsh environment and long distance, Guo Jia died of infection with disease!
Another wild history theory is: Cao Cao had a daughter named Cao Yue, who fell in love with Guo Jia, at that time Guo Jia had a wife, but Cao Yue was also willing to be a concubine, and then Cao Yue married Guo Jia and became a concubine, but Cao Yue had a special hobby for sexual affairs, and agreed that Guo Jia would have sex with him twice a day, and he would double every New Year's Festival, at the beginning Guo Jia was still happy to do this, but after a long time, he felt powerless, and over time, Guo Jia was exhausted! Cao Cao was furious when he heard about this! The name of Cao Yue was removed from the family tree, this is the history of the wild to listen to!
After Guo Jia's death, Liu Beisan took care of Maolu and asked Wolong Zhuge Liang to come out of the mountain, and Zhuge Liang offered advice for Liu Bei, and after the Battle of Chibi, he became a three-legged situation! If Guo Jia didn't die, with his resourcefulness, he might not give Liu Bei a chance to divide the world! The later Three Kingdoms did not exist!
