This is not a simple war epic, but a group portrait of a group of "guardians" in troubled times: they are the general and his wife, the father and mother, the comrades and sisters. When Nie Debo forged the wolf constitution in the arsenal, when Guan Jiu repaired Cian's tiger-headed boots late at night, and when Cao Jie planted the first handful of wheat seeds for the newborn in the Tuntian District, they had already understood that the real armor was never made of black iron, but the determination to let the children sleep peacefully under the eaves, and the persistence to make the refugees smile in the fields.
And Nie Cian, a girl who grew up in armor and nursery rhymes, will eventually bring the spark of her father's generation to let the word "guard" shine with new light in the wider world - because the end of troubled times never belongs to a single hero, but to the tenderness hidden under the armor that is passed down from generation to generation.
