In the turbulent times, the war broke out, and the land of Kyushu fell apart. The cold plains of the north are the first line of defense against foreign enemies, and they are also a Shura field riddled with bones. He is the youngest elite captain in the army. With his iron-blooded skills and decisiveness in killing, he has become famous in the mountains of corpses and seas of blood. He believed in military orders like a mountain and made protecting his family and country his lifelong obsession. However, during a desperate rescue operation, he met the taciturn but excellent medical doctor who was accompanying the army. On the battlefield, he charged into battle and fought bloody battles; in the military tent, the man held acupuncture to heal his wounds and stayed silent for a long night. In the smoke of gunpowder, there is back-to-back trust; between life and death, there is tacit concern. Surrounded by external enemies and surging internal worries, they not only have to face the battle of swords and shadows, but also have to resist the open and secret arrows of the court. There is no romance between flowers and moonlight, only the warmth of shoulder to shoulder on a cold night; there is no promise of eachother, only the tacit understanding of "you defend the country, and I will defend you." Iron blood and tenderness intertwined, faith and affection collided. In this troubled world, they used themselves as shields to protect the mountains and rivers, and also protected the pure pure land in their hearts, waiting for the moon to clear and the wind to return safely.
