Northern Theater Command Special Operations Brigade. Qin Lie was the sharp-edged leader of the Fengmang Special Operations Squad. During a special mission, a mistake in his command led to the deaths of three squad members. Before one of them, a soldier from Northeast China, died, he clutched Qin Lie's hand and said, “Take care of my mother back in the Northeast.” Qin Lie answered through tears, “Don't worry. Your mother is my mother. I'll protect her with my life. I won't let her suffer the slightest grievance.” Blaming himself for his poor judgment, Qin Lie vanished without a word after the mission and went to the Northeast. Bai Xingwan, the only daughter of a prominent Beijing family, had secretly loved Qin Lie. Throughout the four years he was gone, she kept waiting and searching for news of him. The story begins in the countryside, moves to the capital, then returns to the rural Northeast, unfolding a series of remarkable events. It features workplace romance, a soldier's patriotism and sense of duty, the promises and deep bonds between comrades and brothers, and Qin Lie's quest to atone for his mistake. It also portrays the support and aid offered by the government in a martyr's hometown to the families of fallen soldiers, leading to one moving story after another.
