In the past two years, this was the first human Lin En had encountered in this dark world.


    And judging by the stats panel, this person had extraordinary combat abilities.


    "I need treatment, as well as some combat and recovery potions."


    A hoarse voice of a middle-aged man came from beneath the large top hat.


    Lin En immediately stood up, putting on a professional smile, and said, "Welcome, please come in."


    The Demon Hunter strode through the door, and the Soul Lantern hanging at the entrance flickered wildly, almost going out.


    This indicated just how absurdly powerful this Demon Hunter was.


    The Demon Hunter sat at the counter, raising his head to scrutinize Lin En.


    Lin En immediately felt a burning pain on his skin, and just the gaze alone inflicted harm on him, which spoke volumes about this person''s strength.


    "I didn''t expect to meet another living human in this dark world," the Demon Hunter said, glancing at him.


    He took a flask from his waist, took a sip, and a strong, pungent smell of alcohol filled the air.


    [Ding! Task triggered: Treat the Demon Hunter''s injuries. Task reward: 500 Skull Coins, Demon Hunter Favorability +50]


    [Task failure penalty: Death at the hands of the Demon Hunter.]


    [Ding! You have triggered the kinship bond, task failure penalty removed!]


    Lin En''s heart skipped a beat.


    The moment he saw the task failure penalty pop up, he sensed trouble.


    And indeed, it was just as he expected.


    A Demon Hunter roaming the dark world would certainly have no favorability towards any monster, and fortunately, he was also of the Human Race; otherwise, this powerful man would have surely cut him down with a single stroke.


    Lin En steadied his mind.


    He calmly looked at the Demon Hunter and smiled, "May I ask where you need treatment?"


    Under the tall hat, those slightly pale lips moved, and then he took off his cloak and turned around.


    In an instant, Lin En''s pupils contracted.This book''s true home is on another platform. Check it out there for the real experience.


    His entire shoulder was a dark, reddish-black, with chunks of coagulated black blood, looking extremely gruesome.


    The injury was truly terrifying.


    Lin En immediately wondered what kind of being could have injured this Demon Hunter so severely.


    The Demon Hunter rasped, "I was ambushed by a red-clad ghost and nearly lost my life. I won''t let her go, but first, I need to heal my wounds."


    [Ding! The system has completed a preliminary diagnosis for the host. The target''s right shoulder is eroded by ''Black Butterfly'' venom, which has penetrated the target''s bones and is in a serious condition.]


    "Black Butterfly?" Lin En hesitated.


    The Demon Hunter moved slightly, sneering, "You actually know about this poison? Seems I underestimated you."


    Lin En laughed awkwardly.


    No.


    He didn''t know.


    He just subconsciously repeated a key term from the system prompt.


    "System, what is Black Butterfly?" he asked in his mind.


    [Ding! Black Butterfly is an entity in the dark world formed entirely from resentment and necromantic energy, possessing high corrosive and erosive properties on life. If an ordinary creature is contaminated, it will turn into pus and blood within five seconds.]


    Lin En was shocked.


    Without hesitation, Lin En donned a full set of protective gear, including a mask and gloves.


    "Can I treat it?" he asked the system in his mind.


    [Ding! You can attempt to perform a bone-scraping detoxification for preliminary treatment.]


    The Demon Hunter turned his head impatiently, "Can we start?"


    Lin En immediately snapped back to reality, calming his emotions. With a mask on, he seriously said, "Sir, your injury is quite severe, and it seems the venom has already penetrated your bones. If you want treatment, we must first remove the tissue eroded by the poison."


    Lin En raised two boning knives, seriously saying, "We need to perform a surgical debridement first."


    The Demon Hunter hesitated for a moment and asked, "How skilled are you in surgery?"


    Lin En nodded, "Rest assured, I have extensive experience. Although this is my second time using a knife, my last client gave me high praise, so I am confident."


    The Demon Hunter paused for a moment.


    He seemed to be weighing the pros and cons.


    Then Lin En heard the hesitant voice from under the tall hat.


    "Are there any other medical shops nearby?"


    Lin En sharpened his two boning knives, chuckling, "There shouldn''t be any. Even if there were, my teacher would have taken care of them. We don''t allow a second medical shop here, hahaha..."


    "......"


    "......"


    A brief silence, the wind howled, rustling the Demon Hunter''s cloak.


    Then he turned around, exposing his shoulder, closed his eyes, and said, "Fine! I trust you this once, go ahead."


    "Alright!" Lin En''s face showed a satisfied smile.


    The two large knives in his hands clanged against each other.


    Clang—


    Clang—


    Sparks flew.


    It was faintly visible.


    Under the shadow of the tall hat, the corner of the Demon Hunter''s stubbled mouth twitched slightly.


    [Demon Hunter Sanity Value -1]


    For some reason, he felt like he had come to the wrong place. This didn''t look like a medical shop at all; it seemed more like a butcher''s shop.


    Could it be his imagination?


    Why did this seemingly weak boy always give him the urge to turn around and run?


    "Do you need anesthesia?" Lin En asked eagerly, excited.


    "No need."


    The Demon Hunter took a sip of his drink, glanced at him, and said flatly, "Anesthesia would only slow my nerve reflexes. A real man never uses anesthesia."


    Lin En gave a thumbs up with a snap, seriously saying, "Great, I''ve never given anyone anesthesia either, this really plays to my strengths!"


    The Demon Hunter''s heart skipped a beat.


    What did he just say?


    But before he could react, he heard the sound of a knife piercing flesh, and his entire body instantly stiffened.


    He turned his head with a creak, looking at the knife stuck in his shoulder, and said in a daze, "It''s started already?"


    Lin En calmly said, "No, I''m just testing the knife."


    "Oh."


    The Demon Hunter turned his head in a daze, reaching for his flask, instinctively wanting to take a sip.


    But for some reason, his hand holding the flask suddenly trembled a bit.


    But it should be fine, this kid, though unreliable, surely wouldn''t dare to harbor any ill intentions against a dignified Demon Hunter...


    Squelch—


    Demon Hunter (ヾ????)—


    "What the hell are you doing?!" The Demon Hunter turned his head, looking at the second knife stuck in his shoulder, eyes wide with rage.


    Lin En seriously held his toolbox, saying, "Finding the right-sized tool, those two are just placeholders."


    The Demon Hunter, eyes wide with rage, said, "Can''t you put your placeholders on the side? Why do you have to stick them in my shoulder?!"


    Lin En shook his head, calmly saying, "Sir, I''m testing the sharpness of the surgical knives. You should know, if a knife isn''t sharp, the pain during cutting would be more intense, which is highly undesirable!"


    "So as a doctor, I must ensure my knives perfectly match your flesh."


    "And the places where the knives are stuck will be cut away later, so there''s no need for you to particularly care about the integrity of your shoulder."


    The Demon Hunter stood there stiffly.


    Damn, that makes so much sense.


    But was he really not doing it on purpose? Why does it all sound like nonsense no matter how you hear it?!
