The top special forces of the Dragon Kingdom, codenamed "Blood Blade", is the country's sharp blade hidden in the shadows. Recruit Lu Chen stepped into the military camp carrying the mystery of his father's sacrifice, with only a mysterious bullet shell necklace engraved with "Seventh Team, Forever" as a clue. In the purgatory bloody selection, he showed extraordinary perseverance and talent, and won the codename "Night Dire", but he was also involved in a deeper whirlpool.
From life-and-death sniping in the border rainforest to top-secret rescues in dangerous areas overseas, Lu Chen and his teammates fought side by side in blood. Mission after mission, time and time again he gets closer to the truth of his father's sacrifice, and time and time again he comes into contact with the shadows buried deep within the system. When his old faith collapses and his teammates are stained with blood in a foreign land, Lu Chen must make a choice between loyalty and truth, obedience and revenge. Can he tear through the darkness in the name of "Night Dire" and clear the name of his father and the silent heroic soul? In the tempering of blood and fire, a bloody bullet case will witness the birth of a new generation of blood blades and their road to revenge.
