Three Kingdoms: In Cao Cao's Camp, Starting from the Battle of Red Cliffs

Qin Chuan transmigrates to the Three Kingdoms era and becomes a low-ranking clerk in Cao Cao's camp. On the eve of the Battle of Red Cliffs... Cao Cao: “The plague has greatly weakened my army. How should we deal with it?” Qin Chuan: “Just send everyone over to the Sun-Liu alliance, of course. Let them infect each other!” Cao Cao: “Who can go and sow discord between Zhou Yu and Sun Quan?” Qin Chuan: “Jiang Gan can go. He can take the soldiers infected with the plague along, too.” Cai Mao: “This is bad! The Sun-Liu alliance is attacking in the heavy fog!” Qin Chuan: “Don't panic. Fire the arrows!” As the Sun-Liu alliance's army suffered countless casualties, the civil and military officials in Cao Cao's camp watched Qin Chuan with deep admiration. “Sir truly is the most ruthless strategist in all of Cao Wei!”
