One of the black-clad men let out a sharp cry the moment he saw the hidden weapons flying back at them. He dove to the side just in time, barely managing to dodge the volley. But the others weren't so lucky. The returned weapons struck with such speed and force that, in an instant, they were turned into human pincushions.
The gruesome sound of steel piercing flesh made the lone surviving member of the Medusa Gang flinch in terror.
Who the hell is this guy? Wasn't he just here to return some clothes? How does he have this kind of power? There were over a hundred micro-needles mixed in with that barrage—how the hell did he manage to return every single one of them?!
Matthew's voice floated toward him, calm and quiet—like a devil's whisper. "Looks like your buddies are all down. So, what's it gonna be? Sit down quietly, or do I have to send you to join them?"
The man shuddered violently. "I… I surrender…" He slowly stood up, then obediently squatted down by the wall, not daring to make a move.
The room was still dim, but he didn't dare gamble on that. If the man saw even the slightest hint of resistance in him, his death would probably be even more brutal than the others'.
Matthew reached for the light switch and flipped it on, and with a crisp click, light instantly flooded the space, revealing everything that had just happened.
The surviving gang member glanced around and finally saw it all clearly—his comrades were sprawled across the room in grotesque positions, blood pooled thickly beneath them. Their deaths had been anything but quick.
He then turned his gaze toward the doorway where Matthew stood, but he didn't dare meet his eyes. He only looked at the man's figure—tall, upright, dressed head to toe in spotless white.
He's wearing white! On Blackshore Island!
Other criminal groups might have members who were forced into it. But not them. No one stayed in the Medusa Gang by accident. Maybe the first few days were hard to stomach, but after witnessing—no, participating in enough atrocities, they stopped being human.
He knelt beside the scout and pressed two fingers to his wrist. The pulse was almost gone. Had he arrived a few minutes later, the man would already be dead.
Matthew's long fingers brushed lightly across his waist. In a swift motion, the Solitary Nine Needles were drawn.
One by one, nine silver needles pierced into the scout's acupoints with surgical precision.
"This ancient set's barely been passed down, and I've never had the chance to use it till now. Looks like you're one lucky b*stard." As he spoke, Matthew gently flicked the end of one of the needles. The motion sent a resonating vibration through all nine pins at once.
Nine needles in harmony, death locked and life restored—the Needle of Rebirth, a healing technique lost for centuries.

The readers' comments on the novel: Medical Genius Unspeakable Marriage (Matthew Larson)
The story started out really good, but after 400+ chapters, I got exhausted because of the in-laws. There’s just too much pointless chatter and greed. The protagonist is supposed to be strong but turns soft whenever the in-laws are involved—even the wife, yikes. Do they always have to give in to every demand and treat? Too weak. I didn’t get angry, just tired… so I stopped reading 😜...
