Jiang Chi, a cook who was taken to the battlefield as a deserter, backhandedly blew up the enemy's headquarters in a desperate situation, but no one believed it was him.

When the enemy instructor Leng Xiao appeared, Jiang Chi realized that he had been a pawn in a plot. The road to clearing wrongs begins with blowing up the headquarters and ends with uncovering the rotten core of the entire legion.
