Conflicts broke out one after another on the border between the Cold River Federation and the Barlow Kingdom. The undercurrent of the great power game and the complex and ever-changing local situation involved many troops in a test of blood and fire. The grassroots company commander Lin Chaodong was pushed to the front line by the sudden war, fighting side by side with his best friend Zhao Hu, the wise and brave Han Wanqiu, and the scheming Li Wenhao. There are also overt and covert fights within the top ranks of the military, with cutting-edge generals such as Tang Ming and grassroots soldiers such as Lin Chaodong causing trouble. The four volumes respectively focus on the fierce fighting on the front line, the secret war on intelligence, the struggle for power and the fate of the decisive battle, presenting the absurdity of war and the warmth of human nature. Under the multi-line narrative, there are not only hot-blooded breakouts, undercover spy wars, and civil strife, but also interspersed with light-hearted humor and tragic and joyful battlefield trivialities. Finally, it ends with a decisive battle, and everyone's fate is settled.
