In 1940 in Cangyunling, Shanxi, a new regiment of the Eighth Route Army was surrounded by the Japanese Bantian Regiment. The regiment leader Li Yunlong disobeyed the order to retreat and decided to break out of the encirclement head-on.
- **Tactical Genius**: Li Yunlong discovered the location of the Bantian Wing headquarters through accurate judgment, adjusted the mortar firing parameters, and killed the Bantian Wing Captain with only two shells.
- **Battlefield Breakout**: The new regiment all fixed bayonets and broke out of the encirclement from the front under the leadership of Li Yunlong, showing amazing fighting will.
- **Postwar Aftermath**: After successfully breaking through, Li Yunlong was dismissed from his post for disobeying military orders and was transferred to the clothing factory as director. The brigade commander revealed that the headquarters had other arrangements for him.
- **Independent Regiment Crisis**: Kong Jie's independent regiment was attacked by Yamamoto's special agent team and suffered heavy casualties. The headquarters decided to send Li Yunlong to take over and reorganize this demoralized unit.
