Rebirth, Opening Hidden Occupations

Star city.

In the high-end five-star hotel, in front of the french window of the senior suite on the top floor.

A sexy woman with a naked body, her plump breasts were repeatedly slammed by the man behind her, leaving sweat marks on the glass.

Shortly thereafter, the woman let out a moan of relief.

She collapsed into the man's arms exhausted, looked up at his handsome face, smiled and asked, "John, I've asked you so many times before and you didn't agree. Why is it abnormal today?"

John looked at the charming woman in front of him, didn't answer the other person's question, but silently lit a cigarette.

The woman smiled sweetly and began to speculate, "Did you break up with your girlfriend? Or did you run out of money again? As long as you promise to maintain a relationship with me, just say what you want. Money, cars, houses, anything is fine, I won't refuse."

John stated his purpose: "Coco, I need succinylcholine."

"Succinylcholine?!"

Coco's pretty face showed a hint of surprise.

As a professor at a top medical university, Coco naturally knows what kind of medicine this is.

Succinylcholine is a clinical anesthetic that can paralyze someone completely with just 5 milligrams. Without a ventilator to assist breathing, the person injected would suffocate to death. It's also a substance found abundantly in the human body and is quickly metabolized, making it hard to detect medically. Some international criminal organizations use it to commit murders.

In country H, it's obviously a strictly controlled substance.

"Why would a college student like you need this kind of anesthetic?" Coco sat up, her expression turning serious as she looked at John.

She could easily get her hands on Succinylcholine, but this was no joking matter. A misstep could lead to fatalities, potentially dragging her into the mess.

Of course, John couldn't tell her that in two days, the entire Earth would undergo a transformation. After that, mysterious "gates" would appear in various countries.

These came to be known as "Gates to Another World."

On the other side of these gates was another world. Once opened, monsters from that world would start invading Earth, slaughtering humans everywhere.

Only those who awakened, possessing the ability to fight these monsters, would survive in the future.

Becoming a top-tier SSS-ranked awakener meant becoming a revered figure in this world.

John knew all this because—

he was a reborn individual.

Five days ago, he returned to the time right before the gates appeared.

In his previous life, John awakened as an "Alchemist," a support class profession that used healing magic and potions to treat teammates and boost their abilities and attributes.

Being a medical student, John had a natural talent for this and became a "Sanctuary Healer" after awakening and class-shifting six times in just five years.

However, during a high-difficulty gate instance, John was betrayed.

Unexpectedly, his girlfriend, Anna, turned out to be the mastermind behind it all!

Anna fell for some rumor she heard who knows where, thinking that by sacrificing herself, a temple healer, they could break their limits and become divine.

Talk about a bunch of ignorant fools, totally clueless that they were being lured by the dark god's deception.

Thinking back, John's gaze turned icy.

This time around, he wasn't willing to trust anyone.

That meant he had to get stronger on his own.

But as a support class alchemist with next to no combat skills, going solo wasn't really an option.

However, John had come across an ancient book from another world in one of the dungeons he cleared. It outlined a way for alchemists to awaken as the hidden class "Poison Master," but he'd need several top-tier poisons to do it.

That's why he was after the Succinylcholine.

As a "Poison Master," his usual healing potions could now carry various negative effects.

This way, even as an alchemist, he could pack a decent punch in a fight.

John said, "Don't worry, Coco. I need the succinylcholine for an experiment. I promise I won't use it for anything bad."

"But…"

 Coco seemed hesitant.

John's hand suddenly reached under her crotch, with two fingers directly inserted into her pussy. This made her, who had just calmed down, feel a tingling sensation all over her body again, and she squeezed John's hand with her slender legs.

Coco eventually compromised. She knows John very well. He has been a person obsessed with research since his freshman year. He is so handsome that he can definitely become a superstar.

"Okay, I'll help you get the succinylcholine. But John, you have to promise me..." Coco didn't finish speaking before he was once again pinned down by John and began to be fucked violently.

Faced with rough John, Coco not only didn't get angry, but also cooperated even more eagerly.

Two hours later.

John came out of the bathroom after taking a shower and put on his clothes.

Coco was exhausted lying in bed, and his whole body was already a bit disoriented. She had just climaxed a total of four times, and although she felt like she had reached her limit, John still had no intention of stopping.

John poured a glass of hot water and set it by the bedside,

 "Coco, remember to drink some water after sweating so much. I'm heading back now."

...

Driving home, John returned to the apartment he rented just outside the university.

Despite feeling tired, he didn't rest. The "Gate" was opening tomorrow night, and he needed to make all the necessary preparations now.

Opening the door to his storage room, John slipped into a protective suit.

He had transformed this space into a lab, filled with all sorts of equipment. Along one wall, there was a row of neatly arranged terrariums, housing various types of venomous snakes.

King cobras, black mambas, thin-scaled burrowing snakes, vipers...

Apart from the hard-to-keep sea snakes, he had almost all the deadly snakes one could think of. Getting these venomous creatures had nearly drained most of his savings, but that didn't matter to him.

Putting on protective gloves, he started with the king cobra, extracting its venom.

As soon as he opened the glass cabinet, the ferocious snake bit onto his glove, but its sharp fangs couldn't pierce through.

Grabbing the snake by its neck, as the king cobra opened its mouth and swayed from side to side, its fangs resting on the edge of the beaker, it began to inject a large amount of venom.

"That's right, good boy,"

John murmured as he watched the venom accumulate in the beaker, admiring how a single adult male could produce enough venom to kill two hundred people in one go.

With these venoms and the addition of succinylcholine, he would be ready to unlock that hidden class path when the Gate arrives tomorrow.

After collecting the venom, John put the king cobra back into its terrarium.

He quickly collected the venom with a sterilized pipette and transferred it into a plastic test tube.

Having done this once made the process much faster for the subsequent snakes.

Twenty minutes later.

John froze the collected venom in the freezer and then stepped out of the storage room, removing his protective suit.

He sat on the couch, lit a cigarette, and softly said to himself, "Now, just waiting on the succinylcholine…"

...

The next day, at 9:30 AM.

There was a knock at the door of John's rental. He got up and opened it.

Coco, wearing a red low-cut bodycon dress with a white shawl and high heels, stepped into John's apartment.

As soon as she entered, Coco lifted her sunglasses with her hand, curiously looking around the room.

She chuckled and said, "John, are you living in such a shabby place? How about I take care of you and you move to my villa?"

"Let's talk about moving later," John said with a serious look on his face. "Coco, do you have the succinylcholine I asked for?"

Coco pouted, looking somewhat disappointed.

She had made an effort to dress up before leaving the house today, yet John's focus was still on that drug.

Even though she was a bit annoyed, Coco still opened her handbag and took out an ampoule.

"Here, this is the succinylcholine you wanted. I've removed the label, but it's the real deal," Coco handed the bottle to John, reminding him again, "Just make sure not to use it on anyone, got it?"

John carefully put away the bottle and smiled, nodding, "Of course, I promise. By the way, Coco, have you had breakfast yet?"

"I'd rather have you first than breakfast," Coco stepped forward and hugged John's waist. Her shawl and bag fell to the ground. She first lightly kissed John's Adam's apple, and then slowly knelt down.

Coco knelt down on John's feet and reached out to untie his belt.
