Yan Hongyin saved a man.Although he was kind-hearted, he was frail and often coughed up blood.But Yan Hongyin didn’t mind.She lacked nothing – status, martial arts, or wealth.All she required of her husband was that he be good-looking, harmless, and not one of those martial artists that cause trouble on weekdays.He didn’t need to study hard for the imperial examinations or become a high-ranking official; she’d seen enough of those stuffy civil officials in the court.Ah Yu was perfect just as he was.****Sect Leader Yu was saved by a gentle and delicate pharmacist.His rescuer was a fascinating woman: beautiful, skilled in medicine, but without martial arts prowess. The renowned heroes admired by ordinary people were, in her eyes, nothing but troublemaking hypocrites and villains.Initially, he stayed only to recover from his injuries, but later he discovered that his wife seemed to have many unusual and numerous little secrets. For example, the hidden passages in their room, the poisonous carp in the pond, and the countless hidden weapons on her person…****Later.Two groups of men in black arrived outside the thatched hut in the suburbs of the capital.Commander Yan, observing the group trying to capture the Loucha Sect leader’s weakness, pondered for a moment, then put away her hidden blade.-Maintain a gentle and virtuous demeanor.Sect Leader Yu, watching the group attempting to seize the Jinyiwei commander’s weakness, fell silent for a moment, clutching his chest and coughing.-Appear frail and refined.

They call him Ghost.A name whispered in fear across warzones, black markets, and underworld circles.To the world, he's a phantom—a faceless mercenary who leaves no trace but bodies in his wake.To his enemies, he’s a death sentence.To his brothers-in-arms in Graveyard, he’s family.But to himself... he's a haunted man searching for a past stolen in gunfire and smoke.After a flawless mission deep in the Eastern Province, Ghost returns to the hidden forest base he's called home for sixteen years. Yet the victory is short-lived. His foster father, the commander delivers an unexpected order:“That was your last mission.”Now, Ghost—real name Miles Sterling—must step out of the shadows of war and into a world he’s never known. Guided only by a scarred letter, a fading memory, and the voice of a woman he hasn’t seen since the day everything was taken from him.But war forged more than his body and name.Behind the mask, behind the scars, Miles has another secret.One he’s kept hidden even from his brothers in arms.He’s not just a weapon.He’s a ghost with a fortune—a hidden empire he built in silence, across borders and black markets, forged in strategy and blood.A man of many names, and many shadows.Beneath the bullets, tattoos, and silence lies a truth buried in ashes.And Ghost is about to dig it up—one letter, one enemy, one memory at a time.
