Dragon Flame Returns to Its Sheath, Guarding Silently

He was once the sharpest blade of the "Long Yan" special forces, but due to the failure of a top-secret mission, he was stigmatized and retired sadly. He originally wanted to return to ordinary life, but due to his shocking ability to kill enemies, he was secretly recalled by the national "VIP Protection Bureau" and became a "shadow bodyguard" without a file. From then on, what he protects is not the rich and powerful, but the technological giants who are shaking the country; what he fights is not the street gangsters, but the top international mercenaries and the deep-hidden traitors. From the assassination traps in bustling cities to the smoke of overseas battlefields, Lu Qingtian uses his body as a shield and his hands as blades. When the conspiracy "Entropy Increase Plan" sweeping the world comes to light, everyone will become a pawn. And he will use the blood of his enemies and his loyalty to prove: The sharp sword of the country is hidden in the darkness; once it is unsheathed, the whole world will be shocked!
