Yan, born in 19 18, a native of Guandong Mountain, Jilin Province, was once an excellent party member. A young man with a blood feud. Alone, he challenged the remnants of Japanese puppet troops, bandits, bullies and other evil forces entrenched in Guandong Mountain and Black Gobi (note: Black Gobi is a rumor in "The Gun God of the Desert"), and eventually became the number one legendary hero of Guandong Mountain. However, in the face of the death of relatives, friends and innocent people, Yan resolutely cooperated with the People's Liberation Army and finally embarked on the revolutionary road and became a real hero. He is also a lonely young man, who often fights with the enemy alone, and every time he beats the enemy and runs away, making them tremble with fear. To the bully, he is a murderous demon king and a cold-blooded animal, but to the innocent good people he helped, he is a savior, treating his friends and disciples like relatives and family.
