Chu Fan, once a commander of the prestigious Daxia Dragon Guards, saw his career shattered seven years ago when a leaked battle plan led to a disastrous mission, resulting in heavy casualties and his own coma for half a month. Upon waking, he learned that 16 cities had fallen to the enemy, and the Daxia Dragon Guards, due to his disappearance, were falsely labeled traitors. His former love, who had warned him of the plan's leak, was framed by the villainous Li family and executed in a courtroom. Determined to raise their daughter alone, Chu Fan fought tirelessly against foreign threats. After eliminating another wave of overseas forces, he decided to return to his homeland to clear the name of the Daxia Dragon Guards and seek revenge for his beloved.
