A few minutes later.


    Yueyue the Fairy stood up dazedly, allowing Lin En to put a helmet on her like a doll, hang a bag on her, and even pack up the strange tissues he had cut from her body, strapping them to her back.


    He said it could be a memento.


    "A perfect treatment," Lin En gave her a thumbs-up, smiling as he said, "If you think this treatment was satisfactory, please give our shop a like. Next time, we can offer you a 10% discount."


    Yueyue the Fairy quickly hugged her helmet, tears welling up, and said, "Th-thank you, boss. Can I leave now?"


    Lin En looked her up and down, his brow slightly furrowed, spinning the boning knife in his hand as he pondered, "Something seems off. I remember the last time I applied the potion, nothing strange grew on you..."


    His gaze was uncertain.


    "So I''m not sure if there''s been any mutation elsewhere."


    [Black Moth Fairy Sanity Value -10]


    Yueyue the Fairy (?д?；): "No way?"


    Lin En hesitantly asked, "Do you feel anything unusual in your body? If you do, it''s best to mention it now."


    Yueyue held her helmet in confusion.


    "Nothing feels off."


    She curiously put down the package and jumped up and down.


    Her body weight was exactly the same as before.


    If something strange had grown, she would have easily noticed it.


    "Nothing strange," she said curiously, puffing out her chest.


    Lin En sighed in relief, smiling, "That''s good. It means the potion doesn''t always cause mutations. It''s quite commendable. Thank you for your cooperation and testing, hehe—"


    "......"


    Then, with a wave of Lin En''s hand, the little fairy dejectedly flapped her wings, disappearing into the dark mist.


    Lin En felt immensely relieved.


    He sighed.


    Lin En (*￣︶￣) strode back to the operating room, planning to tidy up.Unauthorized duplication: this tale has been taken without consent. Report sightings.


    Who knows when he might encounter such a good customer again.


    But just then.


    Clang—


    The sound of metal clashing came from beneath his feet.


    Lin En''s ears perked up instantly.


    The next moment.


    He saw a bulging bag on the floor, and his expression froze.


    "Wait, this seems to be..."


    He instinctively reached out to open the bag.


    Suddenly.


    The bag was filled with Black Skull Coins, almost blinding Lin En.


    Lin En was instantly shocked.


    Wait!


    Something''s wrong!


    Why is that little fairy''s money pouch here?!


    He clearly saw her chest bulging earlier, almost bursting out of her clothes, and thought she had stuffed the pouch inside.


    But!


    If the pouch wasn''t stuffed in, then what was she pressing against her chest...


    "Could it be, the fake became real?!"


    Lin En''s mind went blank.


    He grabbed the money pouch at an unimaginable speed and rushed outside, but the Black Moth Fairy was nowhere to be seen.


    In his mind, he imagined the little fairy pulling out the real thing next time she tried to pay...


    A terrifying scene!


    Lin En (；д；).


    If that''s really the case.


    He hoped she would realize it soon and come back while the shape was still malleable, so it could be pressed down!


    ......


    Holding the money pouch.


    Lin En continued to sit at the counter, dozing off while waiting for new customers.


    But for some reason, business wasn''t good today.


    Besides the foreign Black Moth Fairy, only a few customers came by.


    In this boredom.


    Time once again reached evening.


    "Isn''t the teacher back yet?" Lin En glanced at the black mist outside, his expression uncertain.


    Today was already the third day.


    Even if the teacher was delayed by something, there should have been news by now.


    Lin En paced back and forth in the hall.


    Although his teacher wasn''t human.


    And usually spoke to him coldly, without the teacher''s care over the past two years, it would have been a dream for a mere human like him to survive in this dark world.


    Not to mention, without the teacher''s guidance.


    He wouldn''t have mastered so many medical and alchemical techniques.


    "Hopefully, the teacher will return by tomorrow morning."


    Lin En worriedly looked at the black mist outside the door.


    He took down the Soul Lantern from the pillar, about to close up shop.


    But just then.


    Suddenly.


    His pupils dilated, and his face twisted in pain as he coughed up a pool of foul, crimson blood.


    Then, under his gaze, the blood began to wriggle and crawl.


    And on the ground before him, it twisted into several menacing blood-red words.


    [DANGER! LEAVE! NOW!]


    Whoosh—


    The six blood-red words lasted only a few seconds before they began to smoke and vanished.


    Almost simultaneously, a system notification sounded in his ear.


    [Ding! You have successfully triggered the mission: Blood Night.]


    [Mission Description: Survive until dawn the next day by any means necessary.]


    [Mission Rewards: 2000 Skull Coins, 2000 Experience, Special Reward x1, Special Achievement x1]


    Lin En''s pupils contracted instantly.


    He quickly crouched down, frowning at the traces where the blood had disappeared.


    "Teacher?!"


    He recognized the handwriting of those six blood-red words at a glance.


    His teacher had used some kind of spell to send him a warning!


    What on earth was happening?!


    Lin En suddenly looked up, frowning as he gazed into the depths of the black mist outside the door.


    And along with the teacher''s warning, the system had triggered a mission, and compared to the previous survival missions, the rewards this time were several times better.


    Even more generous than the day with the root monster!


    This clearly indicated that the crisis this time would be extremely severe!


    What could it be?!


    Could it be that the teacher encountered a crisis outside, and it spread to his Blood Saw Apothecary?!


    Without any hesitation.


    Lin En quickly calmed down and rushed back into the shop at an unimaginable speed.


    [Flesh Growth Potion] [Faceless Demon Heart] [Demon Hunter''s Revolver] [Boning Knife] [Soul Lantern] etc.


    These were the various special items he had acquired over time.


    And they were his greatest reliance now.


    He chose not to stay.


    Because since the teacher had sent a warning, staying would surely mean grave danger!


    "I''ll spend the night at the Blood-Clad Wraith''s place. Although I might be violated, it''s definitely safer than staying here!"


    Lin En packed up, lifted his head, and quickly stepped out the door.


    Whoosh—


    A chilling wind blew from the depths of the black mist.


    Lin En''s foot, just stepping out, froze instantly.


    In the depths of the black mist.


    A massive silhouette slowly emerged in his vision.


    Thud—


    Thud—


    The next thing he heard.


    Was a series of heart-pounding footsteps.


    And the pitch-black mist, for some reason, began to turn blood-red, a pungent, indescribable stench of blood rolling towards him.


    [Warning! Warning! ??? has increased your Crisis Level to 100%]
