Chen Mo, a graduate of the Department of Modern History, accidentally traveled to Jian'an for three years in the Eastern Han Dynasty and became an ordinary soldier under Cao Cao. He had no system to rely on, only the solid knowledge of the history of the Three Kingdoms in his mind.
When he first entered the military camp, Chen Mo relied on his prediction of the "Belt Edict" incident to help Cao Cao avoid the assassination, and barely gained the attention of counselor Xi Zhicai. After that, he refined the household registration and water conservancy planning of the farming system in response to the grain shortage in Yanzhou; before the Battle of Guandu, he put forward suggestions for strengthening the defense of Wuchao grain road; he also improved the counterweight structure of the trebuchet to improve the efficiency of siege.
He was well aware of the direction of history but did not dare to overturn it rashly. He could only offer suggestions with "humble opinions" at key moments, and gradually grew from an unknown person to a trusted advisor to Cao Cao. During the expedition against Lu Bu, Yuan Shao, and Jingzhou, Chen Mo accompanied Cao Cao, trying to make up for historical regrets, help Cao Wei defeat the heroes, and finally unify the nine states.
