Modern young man Chen Feng accidentally travels across the Three Kingdoms and joins the army of Liu Bei, who is known for his benevolence. With his advanced historical understanding and strategic thinking, he assisted Liu Bei to overcome difficulties repeatedly - from the battle of Changlinpo to alert Liu Bei to avoid pitfalls, to helping him stabilize Shouchun's recruitment and consolidate the rear, and to prove his talent when Xu Shu recommended Zhuge Liang, promoting the "Three Visits to the Thatched Cottage".
From then on, Chen Feng worked in tacit cooperation with Zhuge Liang, Xu Shu and other advisers, providing details of the fire attack in the Battle of Chibi, planning grain and grass supplies in the Battle of Shu, and formulating strategies to lure the enemy in the Battle of Hanzhong. Along the way, he assisted Liu Bei in gathering people's hearts and expanding his territory, and finally helped him establish the foundation of the Shu Han Dynasty, realize his long-cherished wish of "supporting the Han Dynasty", and became an indispensable "minister who rides the wind" beside Liu Bei in the troubled times of the Three Kingdoms.
