On the night when flames burned the city, the broken sword was broken in the hands of the enemy chief. Jiang Zhaohan was in a deadlock. Shen Shuwu sneaked into the enemy camp alone and stained his shirt with blood. Three years later, he returned to his homeland with scars all over his body and a remnant of his army, just to regain the broken sword that symbolized the soul of the army. She is no longer just a rear medic, but a Night Owl commander wearing armor and wielding a sword. When the cavalry broke through the city gate and when the fire oil poured on the enemy formation, the two met again in the center of the ruins - he held the sword, she held the knife, and the cracks in the past turned into battle scars of life and death. This is not only a battle to restore the country, but also the final chapter in rebuilding the dignity of the military with blood and fire.
