In modern times, when wars are rife and mountains and rivers are broken, young people full of sincerity join the military, determined to protect the common people with iron and blood. He passed the test and joined the elite special forces, but he failed to find the pure glory he expected. On the training ground, behind the strict standards is an imbalance in resource allocation, and background quietly affects the path to promotion; when performing tasks, in addition to the test of life and death, they also have to deal with the undercurrent of factionalism, and useless formalism consumes the efforts of soldiers. He has seen his comrades die for unreasonable orders, he has seen his illustrious military achievements being ignored by bureaucrats, and he has seen his ideals gradually dim in the quagmire of reality. In the hail of bullets, he not only has to face the external enemies, but also resist the internal corruption. In the collision between his original intention to protect his family and the country and the cruel reality, he struggled repeatedly between persistence and compromise, and moved forward with passion and coldness. With graceful and delicate brushstrokes, the work sheds away the aura of the special military, directly points to the systemic shortcomings and the complexity of human nature behind it, and writes about the pain and perseverance of individuals in troubled times between mission and reality.
