Guo Jia's Rebirth: Cao Cao's Destiny-Changing Situation

In the twelfth year of Jian'an, Guo Jia died of illness in Liucheng at the age of thirty-eight. Before he died, he looked at the vast sky in the north, full of unwillingness in his heart - he knew very well what detours Cao Cao's camp would take next: the fire of Chibi, the embarrassment on Huarong Road, the defeat of Hanzhong, Guan Yu's missed opportunity to move the capital during the Northern Expedition... The seeds of all tragedies were planted long before Cao Cao was satisfied. What if I could do it all over again? When Guo Jia opened his eyes, he found that he had returned to the first year of Jian'an. Cao Cao had just welcomed the emperor and moved his capital to Xu County, and it was a time when everything was in ruins. He is no longer the counselor coughing up blood on the hospital bed, but the high-spirited "ghost" - twenty-six years old, with a clear mind and a strong body. In this life, Guo Jia decided to change everything. He not only assists Cao Cao in unifying the world, but also helps Cao Cao avoid those deadly traps. However, the inertia of history is far beyond imagination - will Xun Yu still be martyred for the Han Dynasty? Will Liu Bei still flee to Jingzhou? Will Zhou Yu still set fire to Chibi? More importantly, can Cao Cao's suspicious and jealous heart really be completely reversed?
