Lin Fan, a college student in the Department of Modern History, woke up and transformed into Lu Bu, the most powerful general of the Three Kingdoms - in a desperate situation where Xiapi was flooded and his life was hanging by a thread! Faced with Cao Cao's 100,000-strong army besieging the city, with no food or reinforcements inside or outside, Lin Fan originally thought that he would become the wronged soul on the White Gate Tower, but at this moment he activated the [Civilized Expedition System]. Starting with bonus points, talent radar, and epidemic prevention guides, he decisively ordered the entire city to spread lime, drink boiled water, and set up isolation areas, and used modern medicine to fight the plague; he improved stirrups and saddles, made composite bows, and used technology to crush Cao's cavalry; he even recruited Taishi Ci, Xu Sheng, and Chen Qun to conquer people's hearts and accumulate strength. From breaking out of the siege of Xiapi to farming in Guangling, from joining forces with Yuan to drive Cao to drinking horses in the Yangtze River, Lin Fan used Lu Bu's body to practice modern wisdom, using information gaps and systematic black technology to stir up the situation in the Three Kingdoms. Cao Cao retreated in shock, Sun Ce was defeated, and Liu Bei looked sideways - when the trajectory of history was rewritten by him, the real chess game in troubled times has just begun!
