The wind and snow are pressing down on the environment, but the cold plum blossoms on the battlefield do not bow their heads. Lu Ye led his suicide squad deep into the enemy's rear, and even though he was seriously injured, he was still one against ten; Huo Ye tried to protect her and cut off the enemy's back, but refused to take a step back even though the battlefield was stained with blood. Are they friends or foes, blades or shields? In the smoke of gunpowder, she used blood as ink, and he used life as pen. In the desperate situation that no one knew, they wrote military orders that only the two of them could understand. When the command post was blown into ruins and when the last signal bomb burned out, they still stood side by side - not lovers, but they understood each other better than anyone else in life and death.
