Dragonflame Sheathed, A Silent Guardian

He was once the sharpest blade in the "Longyan" special forces, but after a top-secret mission failed, he was disgraced and forced into a quiet retirement.

He had hoped to live an ordinary life, but his astonishing skill at killing enemies led the state-level "VIP Protection Bureau" to secretly call him back. He became a "shadow bodyguard" with no official records.

From then on, the people he protected were not heiresses from wealthy families, but scientific giants whose work could shake the foundations of the nation. The enemies he faced were not street thugs, but elite international mercenaries and deeply entrenched traitors.

From assassination traps in bustling cities to the smoke and gunfire of overseas battlefields, Lu Qingtian became a shield with his body and a blade with his hands.

When the global conspiracy known as "Entropy Increase" came to light, everyone would become a pawn. He would prove, with his enemies' blood and his own loyalty, that the nation's sharpest blade lurks in the darkness, and when it is finally drawn, the whole world will tremble!
