Introduction to "The Decline of Han Zuo: The Biography of Chen Yun, the Counselor from Another World"
Chen Yun, a doctor of modern history, traveled to the Guandu battlefield in the fifth year of Jian'an due to a laboratory accident and became an unknown soldier in Yuan Shao's army. With his precise insight into the history of the Three Kingdoms, he saw through the fatal loopholes in Yuan Shao's camp and took the risk to defect to Cao Cao with the Wuchao defense plan. He used the strategy of "attacking Wuchao to burn grain and grass at night" to help Cao Cao reverse the situation in the Battle of Guandu, and he has since become one of Cao Cao's camp counselors.
Faced with the temptations and doubts of top advisers such as Cheng Yu and Guo Jia, Chen Yun used his extraordinary resourcefulness to resolve the problem: he offered advice to "slowly pursue the Yuan family and sit back and watch the internal fighting" to help Cao Cao easily wipe out the remaining forces of Yuan Tan and Yuan Shang. Unify the north; before the Battle of Chibi, he strongly advised Cao Cao to be wary of the Sun-Liu alliance and the hidden dangers of water wars. Although it was not adopted, he helped Cao Cao regain his strength after the war with the strategy of "consolidating the north to raise troops and dividing Sun and Liu".
Using a modern historical perspective as a blade and ancient strategies as a shield, in the turbulent Three Kingdoms era, with his precise layout and brilliant writing style, he gradually became the core adviser that Cao Cao relied on. He not only rewrote his personal destiny, but also wrote a legendary journey of a counselor from another world in the construction of Cao Wei's foundation.
