Li Hanchuan led his troops to sneak behind enemy lines and captured a skilled female spy. The coldness in her eyes reminded him of his wife who died in battle three years ago. He vowed to pry her mouth open, but his heart ached suddenly under the old scar on the side of her neck - it was actually the mark that he had bandaged her with his own hands. She said nothing, only caressing the bullet holes in his uniform late at night, as if she was already familiar with every scar. When the smoke buried the truth, he realized that what was swallowed by the sea of fire was never her life, but the regret that he did not dare to face.
