The outpatient department of an Eighth Route Army hospital in Hebei was attacked, and Wu fled the Japanese army with illness. Later, Wu took Fang Biyi, who was originally an individual anti-Japanese armed force, to look for a large army to go south. The Japanese commander Hayano vowed to kill Wu Weiyou for revenge and pursue all the way.

Everyone evaded the pursuit, rescued teammates and rebuilt the team, and successfully entered the south to return to construction. Then, the Japanese army opened up a large area of Qing Xiang with hedges. The development strategy must be that Wu Thirteen led a task force to Qing Xiang to carry out anti-rape, protect precious cultural relics and support large troops to carry out anti-fitness activities.

During the action, Wu Thirteen accidentally met Wu Shan, the second brother of the Kuomintang for many years. Wu Shan persuaded Wu Thirteen to join the Kuomintang, and Wu Thirteen refused the invitation.

Wu led a small group of troops with the advantage of rich experience in ambush operations, which became a great misfortune for the Japanese army. Facing Wu He's team, he is more and more brave. Under the Japanese army's multiple panic attacks, Wu led a team to fight bravely and finally entered the victory of War of Resistance against Japanese Aggression.
