Li Feng was falsely accused of collaborating with the enemy to destroy his family. He faked his death and lurked for three years. He led the rebel "Black Crow Army" back to the military area and vowed to kill Zhao Wujiu and other senior officials. Shen Zhao used intelligence as a blade, Liu Rushuang used medical skills as a shield, Han Lie led the Broken Sword Battalion as a vanguard, and Chen Ya's silent testimony became the last straw that crushed the truth. When blood stains the military flag, who is the real traitor? This revenge is not only for innocence, but also for the vindication of the entire military soul.
