Chu Fan joined the army seven years ago and rose through the ranks to become the commander of the Dasha Dragon Guard. However, during one operation, his battle plan was leaked, leading to a misjudgment and numerous deaths. He himself also fell into a coma for half a month. When he woke up again, he learned that sixteen cities of Dasha had been lost. Because he was missing, Dasha also classified the Dasha Dragon Guard as a rebel force. The original female protagonist was falsely accused by the antagonist Li family for having leaked the battle plan before it was revealed, and was sent to the court for execution. Chu Fan raised his daughter alone. After eliminating another wave of foreign forces, he decided to return to his homeland to clear the name of the Dasha Dragon Guard and avenge the original female protagonist.
