In an instant.


    (ΩДΩ)！！


    Her long hair, which drooped to her ankles, suddenly stood on end.


    Behind the curtain, a blood-soaked young man with a chainsaw (〝▼皿▼) was straddling the demon hunter, grinding the chainsaw against his shoulder with a screeching sound.


    Sparks flew, and bone fragments scattered.


    And as if noticing the customer outside the curtain, Lin En suddenly looked up, seamlessly switching to a professional smile, revealing his gleaming (and somewhat sinister) teeth, and said:


    "Welcome, we have plenty of potions. Please come in and wait a moment. Once I''ve dealt with this customer, I''ll get yours. It won''t take long, hehehe—"


    Lin En let out a friendly laugh.


    [The Fear Level of the Long-Haired Ghost towards you +30]


    [The Fear Level of the Long-Haired Ghost towards you +40]


    "Ah—ah—"


    The long-haired ghost clutched her head, letting out a terrified wail (ΩДΩ).


    Under Lin En''s stunned gaze, the long-haired ghost, screaming, abandoned her feet and hobbled into the black mist, clutching her head.


    [Ding! Your Fame in Wandering Soul Alley +1]


    [Ding! Your Fame in Wandering Soul Alley +1]


    [Ding! You successfully scared a customer into a psychological disorder. The personality trait of the Long-Haired Ghost has changed from "Lively" to "Timid." You have earned the achievement: Customer Scare Specialist!]


    [Customer Scare Specialist]: Due to your excessive eccentricity, you often cause customers to become overly frightened. The apprentice of Blood Saw Apothecary is on a path of no return... You have gained a permanent layer: Customer Fear Level towards you permanently +1, Pain Inflicted +1


    Lin En was taken aback.


    Countless "???" floated above his head.


    How did I become a Customer Scare Specialist?!


    I''ve always adhered to the principle of putting customers first, treating them sincerely, and serving with a smile!


    This stupid system can''t just randomly assign weird achievements to people!


    Stolen novel; please report.


    "Trying to run?!"


    Lin En (╬￣皿￣) grabbed the demon hunter crawling forward and went at him with the chainsaw.


    "Never mind, let''s fix this patient first!"


    Screeching sounds filled the air.


    "God! Oh God!"


    Finally.


    After more than ten minutes.


    Lin En, immensely satisfied, tossed aside the chainsaw, smiled at the polished, smooth white bones, blew on them, and said:


    "Customer, it''s done! The toxins that had eroded into the surface of your bones have been completely cleaned out. Now, you just need to let the flesh regenerate further, and your arm will be as good as new!"


    Lin En wiped the sweat from his forehead, showing an earnest smile of pride after hard work.


    This feeling of saving a life outweighs building a seven-story pagoda, truly gives one a sense of transcendence.


    "Customer, are you satisfied?"


    "Customer?"


    Lin En turned his head in confusion.


    And immediately saw the demon hunter''s body convulsing continuously, (?Д?), with countless white foam bubbling from his mouth, his eyes rolled back almost out of sight.


    "Customer! Customer!!"


    Lin En was shocked.


    ...


    More than half an hour later.


    [Ding! You used special means to incapacitate a legendary demon hunter beyond your level, earning the achievement reward: Pain Inflictor!]


    [Pain Inflictor]: Achievement title, permanently increases the pain value inflicted by the host using various tools by +5%


    Lin En listened blankly to the absurd system prompt echoing in his mind.


    And on the operating table in front of him.


    The demon hunter finally began to regain consciousness from his stupor.


    "You''re awake?"


    As soon as he opened his eyes, they reflected Lin En''s professional smile.


    With a start—


    Almost reflexively, the demon hunter jumped off the operating table in terror, firing a dozen shots in Lin En''s direction.


    "Stay back! Stay back!"


    [Demon Hunter''s Sanity Value -10]


    [Demon Hunter''s Sanity Value -5]


    [Demon Hunter''s Sanity Value -1]


    He was terrified, holding a revolver, still shaken.


    Opposite him, Lin En stood wide-eyed, leaning against the wall in a "big" shape, the dozen bullets precisely outlining his silhouette.


    "Calm down! Please calm down! Forget those unpleasant memories, rest assured, I''ve already treated your injury!"


    Lin En raised his hands, speaking authoritatively.


    He discreetly nudged the chainsaw at his feet aside, preventing the customer from recalling any unpleasant memories.


    The demon hunter panted.


    Struggling to calm himself.


    Then he turned his head to look at his shoulder.


    There, wrapped in thick bandages, his shoulder no longer felt the emptiness of being skinned, nor the tearing sensation from the Black Butterfly''s poison, except for some stiffness when moving.


    It was as if the previous terrifying experience had been a dream.


    The demon hunter was astonished: "So fast?"


    Lin En earnestly replied: "It''s almost fully recovered. After removing the poisoned, infected muscle tissue and superficial bone fragments from your shoulder, the only remaining issue is how to quickly regenerate your flesh."


    Lin En held an empty potion bottle.


    "I used the best flesh-regenerating potion from our shop, and given your extraordinary constitution and strong vitality, most of the missing flesh has already grown back."


    "Only a small central part was too far from surrounding tissue, so I supplemented it with some other meat. Rest assured, I''ve eliminated any rejection!"


    The demon hunter was stunned.


    He tore off the bandage on his shoulder.


    His shoulder was indeed restored, pink and tender, with a small part at the center showing a different skin tone, with a single hair standing upright.


    [Pork!]


    The demon hunter''s hair stood on end, grabbing Lin En by the collar and lifting him up, glaring and grinding his teeth.


    Lin En quickly raised his hands, indicating innocence.


    "Customer, although the process might have been unpleasant, the result is perfect, isn''t it?"


    Lin En blinked, his survival instinct in full swing.


    "And I can assure you, if any issues arise in the future, you can come back here anytime for a free follow-up service, guaranteed satisfaction!"


    The demon hunter trembled: "Follow-up service?! You''re still thinking of giving me a follow-up service?!"


    [Demon Hunter''s emotions extremely unstable.]


    [Crisis Level +30%]


    [Crisis Level +50%]


    [Crisis Level +99%]


    "Customer!" Lin En said seriously: "I''m a doctor. Although there were some minor hiccups during the treatment, think about it!"


    "Compared to the Black Butterfly spreading and rotting your body to death, what''s a little pain from scraping bones to heal?"


    "Living is more important than anything!"


    [Soothing Experience +1]


    [Soothing Experience +1]


    [Ding! Target''s Danger Level decreasing...]


    Finally.


    Under Lin En''s barrage of toxic positivity, the demon hunter finally ground his teeth and released Lin En''s collar.


    The demon hunter took a deep breath, let Lin En go, and gritted his teeth:


    "As expected of my kin, surviving in the dark world, you truly have skills! Your methods of tormenting people are indeed top-notch!"


    Lin En scratched the back of his head, chuckling: "You''re too kind! You''re too kind!"


    "You think I''m complimenting you?!"


    The demon hunter grabbed Lin En''s collar again, eyes wide with rage, grinding his teeth:


    "Have you ever performed surgery on anyone before?!"


    Lin En quickly shook his head, raising three fingers, earnestly: "I swear I''ve done it, I just performed a C-section! And both mother and child were safe! They even gave me a thumbs up!"
