Amid the flames of war in Chibi, Chen Mo traveled through thousands of years, activated the mysterious "Beichen System", and used modern knowledge to break the troubled times of the Three Kingdoms. He first followed Zhou Yu to guard the east of the Yangtze River, outsmarted Cao Wei's undercover Lin Jingwen (a traveler from the Republic of China), from Ruxukou to defeating modern tactics, to secretly helping Lu Meng cross the river in white at Xiangfan, guarding historical nodes step by step. In the Battle of Yiling, he and his old enemy fought side by side against Cao Wei's sneak attack. They had a heart-to-heart talk at Linjiang Pavilion, and their obsessions melted away - from killing each other to cherishing each other, and they vowed to "go home" together.
