Su Yan, the gray-eyed intelligence agent code-named "Nightingale" within the Federal Parliament, uses his extraordinary insight and calm analysis ability to walk on thin ice in the undercurrent of the whirlpool of power. She is loyal on the surface, but in her heart she is full of doubts about the truth concealed by the Federal Parliament, and vows to uncover the layers of mystery. Wei Dongsheng, the youngest commander of the Spark Alliance, codenamed "Gale Wind", he is brave and adept at fighting, has a firm belief, and is a sharp sword in the resistance army.

From fighting each other with swords to fighting side by side, they gradually build trust beyond the camp in the war-torn ruins. Facing a desperate situation, they must join forces, not only to survive, but also to uncover a shocking conspiracy that can subvert the future of mankind and ignite a glimmer of hope for rebirth for the civilization on this scorched earth. This is not only a war, but also a starry journey about faith, sacrifice and redemption.
