Three Kingdoms: Take the Map and Defect to Liu Bei

[Three Kingdoms Travel] [System Warning] [History Rewriting] [High-Inflammation Counterattack] Su Chen, a modern backpacker carrying a mountaineering bag, stepped on the wrong foot and traveled to the wilderness of the late Han Dynasty in the first year of Jian'an. Just when he was about to die of dehydration and starvation, a defeated army passed by - the leader was Liu Bei, who had droopy ears and shoulders, followed by the red-faced Guan Gong and the black-faced Zhang Fei. Su Chen was thrown on the cart like a savage, and no one looked at him. But there was a system in his mind to seek advantages and avoid disadvantages, and he called the police frantically: there was a large-scale ambush ahead in Guangling, and the danger level was extremely high! Seeing that the army was about to plunge into a dead end, Su Chen lay on the cart and shouted: "We can't go to Guangling!" Zhang Fei exploded on the spot: "You savage knows nothing!" Su Chen was neither anxious nor annoyed. He explained Yuan Shu's ambush and Liu Bei's predicament clearly in a few words, even saying "I have to lose my underwear." Liu Bei broke out in cold sweat, got off his horse, and bowed in public: "Sir, please teach me!" Su Chen took out the map, which was a hundred times more precise than any other map, and pointed at Haixi: "Go here. Someone will send food and money." No one believed it. Until Mi Zhu kneeled at the city gate with two thousand bushels of grain and five million gold and silver—— Liu Bei held Su Chen's hand tightly: "Sir, where did you see this incredible wealth?" Su Chen pointed to the map: "It told me."
