He had half a plum blossom sewn on his sleeves, and when he returned, he brought the "tomorrow" of four women with him, which was written into the gaps in history. This is a legend about protection and faith in troubled times, about how a boy grows from a "wild child" to a warrior, and how a girl sticks to her original intention in the flames of war. Open this book and you will see - a wild child who climbs the wall like a civet cat and a stubborn girl embroidered with plum blossoms meet on the bluestone slab. They agreed to protect the light in their hearts together, but were forced to separate in the undercurrent of troubled times. Many years later, when the war burned his homeland, he became a warrior walking through the smoke, and she fell into the glacier with the unfinished plum blossoms. The gears of fate are turning, hatred and redemption, betrayal and perseverance are intertwined in the smoke of gunpowder - some people use the warmth of sunflowers to warm half a broken plum, and some people are waiting for reunion in blood and fire. When the map of Meihuagou becomes the coveted prey of the Japanese army, they will eventually understand: some bonds are more burning than the flames of war and longer than the years.
