In 1942, the Zhengtai-Taiwan Railway was at war.
Zhao Hengde, the reconnaissance hero of the Taihang Military Region, has a wild goose feather sword and a solitary bravery, writing legends on the battlefield behind enemy lines.
He lurked deep in the Taihang Mountains, a "lone wolf" who frightened the Japanese invaders, and a steel barrier protecting his homeland.
He used surprise attacks to blow up military columns, destroy bridges, and end strongholds, cutting off the enemy's supply lifeline.
Alone deep into the enemy camp, he used the most powerful tactics to complete the seemingly impossible task.
There are no earth-shattering slogans, only walking on the tip of a knife, and the faith of the family and country engraved in the bones.
Look at the lone wolf in Taihang, using a sharp blade as a blade and blood as a torch to kill all the jackals and protect our mountains and rivers!
