Lin Yue, a graduate student in the Department of Modern History, accidentally traveled to Jingzhou in the 24th year of Jian'an (AD 219) and became Guan Yu who was preparing for the Battle of Xiangfan. Knowing that "when Xiangfan goes, Maicheng will surely perish", he suppressed his obsession with the Northern Expedition and argued against all opinions on the grounds that "his arm injury has not healed and Jingzhou needs to be consolidated", vowing to defend half of the Shu Han country.
On the one hand, he ordered Mi Fang and Fu Shiren to lead the infantry to attack the grain road in Fancheng, and use the "hook formation" and "fish scale formation" to tire out the enemy; on the other hand, he built the Jingzhou Navy, using building boats, rackets, and fighting ships and crossbows to build a strong defense line on the Yangtze River, so that Sun Quan's conspiracy to "cross the river in white" was aborted. In order to break the dilemma of "weak generals and weak soldiers", he formed the "Qianlong Department" special dead soldiers, sneaked into Runan to capture Deng Ai's mother and Luoyang Kou Zhonghui's family, and subdued the two wizards with kindness and power. He also teamed up with Qiang Humadai and Tongjia Shixie to provide food and grass and strong cavalry to build Jingzhou into an indestructible foundation.
Facing Cao Ren's heavy troops in Fancheng and Yu Jin's seven armies, he took advantage of the heavy rain in the Han River to launch a water attack and annihilated tens of thousands of enemies with water, infantry, and cavalry. In response to Sun Quan's false alliance, he extorted grain and horses, captured Lu Xun's family and forced him to withdraw; to deal with Cao Wei's internal conflicts, he alienated Sima Yi and the Cao family, and disrupted the enemy's combat power.
From guarding Jingzhou to seizing Xiangfan, from pacifying Nanyang to conquering Chang'an, and finally annihilating Cao Wei and pacifying Soochow, Lin Yue, as Guan Yu, and other famous generals such as Deng Ai, Zhong Hui, Ma Dai, relied on precise tactics and ruthless tactics to reverse the historical decline, help Liu Bei revitalize the Han Dynasty, and let the banner of "Han Zuo is immortal" fly again in the Central Plains.
