Ultimate Spin System: Ero Spin?-Chapter 93 - Another Target

Lucas barely dodged the slime core as it splattered against a nearby tree, leaving a faint, shimmering residue. He shot Lena an exasperated look.

"Can we just—focus?" he muttered, stuffing the last core into his satchel. "This stuff is valuable. Let’s get it back to the guild."

Lena crossed her arms, still fuming but ultimately relenting. "Fine. But I swear, if your Spin Attack pulls another—another thing next time, I’m walking."

Lucas rolled his eyes and gestured for her to follow. "Noted."

By the time they reached the guild, the sun was dipping below the horizon, casting long shadows over the cobblestone streets. The grand wooden doors of the Adventurer’s Guild loomed before them, its symbol—a golden sword crossed with a quill—etched into the wood.

Lucas pushed open the doors, and the usual buzz of voices, clinking mugs, and the occasional rowdy adventurer filled the air. The scent of ale, roasted meat, and sweat mixed together in the lively hall.

As they stepped inside, a few heads turned their way. Lucas didn’t think much of it—until the murmurs started.

"Hey, isn’t that the guy who took down a D-tier monster?"

"Yeah, the lava slime boss! I heard it was insane!"

"I heard he froze the entire thing in a single attack—like, completely shut it down."

"Damn. That’s some real power."

Lucas felt a prickle of unease crawl up his spine. He exchanged a look with Lena, who raised an eyebrow.

"Looks like someone’s been talking," she muttered.

"Great," Lucas sighed. "Just what I needed—attention."

Ignoring the whispers, they made their way to the guild’s reception counter, where a familiar face greeted them.

Sarah, the ever-efficient guild receptionist, was flipping through a massive tome of adventurer records when she noticed their approach. She was a petite woman with sharp eyes, her dark hair pulled into a neat ponytail.

She glanced up, her gaze briefly scanning them before locking onto Lucas with an unreadable expression.

"...You’re causing quite the stir, Lucas."

Lucas scratched the back of his head. "Yeah, I noticed. Look, we just came to turn in some slime cores and the herbs we collected."

Sarah folded her arms. "You just came to turn in materials? Nothing else? Like, oh, I don’t know... soloing a D-tier monster?"

Lucas stiffened. "...Technically, it wasn’t solo. Lena was there."

Lena threw her hands up. "Hey, don’t drag me into this. I was running for my life while you were out there summoning—whatever that was."

Sarah sighed, rubbing her temples. "Alright, let’s see what you’ve got."

Lucas pulled out the slime cores, placing them carefully on the counter. They glowed faintly, pulsing with residual heat and mana. Even Sarah’s usual composure faltered slightly as she examined them.

"These... are exceptionally high-quality." She looked up, eyes sharp. "And you really took down a D-tier monster?"

Lucas shrugged. "Yeah, I guess."

Sarah sighed again and flipped open the ledger in front of her. She dipped a quill into ink and began writing. "Well, whether you ’guess’ or not, you did it. And that means..."

She stamped a document and slid it toward them.

[ Adventurer Rank Promotion Notice ]

[ Lucas & Lena – Promoted to Silver Rank ]

Lucas blinked. "...Wait. What?"

Lena grabbed the paper before he could and scanned it. "We’re—Silver Rank now?"

Sarah nodded. "Taking down a D-tier monster without assistance from higher-ranked adventurers is considered a major achievement. Normally, we’d need a detailed report, but considering the number of witnesses and how fast the news spread... it’s official."

Lucas let out a slow breath. He hadn’t expected this. Adventurer ranks were hard to climb—most people spent years stuck at Bronze, struggling with low-tier quests.

And now? They’d skipped ahead.

Lena looked up, grinning. "You know, this means we get access to better quests, better rewards—hell, even better gear."

Lucas hesitated. It was an opportunity. But at the same time, something in the back of his mind whispered that things were moving too fast.

Sarah closed the ledger and gave them a level look. "Congratulations. But be careful—higher rank means higher expectations. People will start paying attention."

Lucas met her gaze and nodded. "Yeah... I figured."

Sarah smirked. "Good. Now, I assume you’ll want your payout?"

Lena’s eyes practically sparkled. "Yes. Absolutely yes."

---

Their earnings from the slime cores and herbs were substantial—far more than they’d expected. Lena was practically vibrating with excitement as she pocketed her share.

Lucas, however, felt the weight of their newfound reputation settling on his shoulders. The guild hall still buzzed with whispers, and he could feel the eyes of other adventurers sizing him up.

This wasn’t just about ranking up.

People were going to start watching him.

And, considering how his powers tended to manifest... he had a sinking feeling that his next spin would be just as ridiculous.

As they stepped out of the guild, Lena stretched her arms and exhaled contentedly.

"Alright, now that we’re Silver Rank, what’s the next move?"

Lucas stared ahead, the town’s lanterns flickering in the evening light.

"...Honestly? I think we should lay low for a bit."

Lena snorted. "Yeah. Because you are so good at avoiding attention."

Lucas groaned. "Look, let’s just take some normal quests for now. No more boss fights, no more chaos."

Lena smirked. "No more cocks?"

Lucas shot her a glare. "I swear—if you don’t drop it—"

Lena just laughed, slinging an arm around his shoulders. "Relax, Silver Rank Adventurer. We’ll take it easy."

Lucas sighed, knowing deep down that fate—or rather, his godforsaken Spin System—wasn’t going to let that happen.

Not one bit.

As the last rays of sunlight dipped below the horizon, Lucas and Lena found themselves strolling through the bustling streets of isekai town. The town was alive with the glow of lanterns and the chatter of merchants closing up shop. The air smelled of roasted meat, fresh bread, and the faintest hint of ale from the nearby taverns.

Lucas exhaled, rolling his shoulders. "Alright, we should probably find an inn before it gets too late."

Lena stretched her arms lazily. "Agreed. After all, we are now Silver Rank adventurers. We deserve a good night’s rest."

Lucas smirked. "Don’t let it get to your head. We’re still broke compared to real high-rankers."

Lena suddenly spun on her heel, blocking his path. "Speaking of money..." She held out her hand expectantly. "Hand it over."

Lucas frowned. "Hand what over?"

Lena grinned. "The gold. Your share."

Lucas narrowed his eyes. "Why?"

"Because, dear stepbrother," she said sweetly, "as a responsible younger sister, I’ll be managing our finances from now on."

Lucas blinked. Then scoffed. "Oh, hell no."

Lena pouted. "Come on, Lucas. You’re the type to blow all your money on useless weapons and weird gadgets. I’m just protecting our future."

Lucas crossed his arms. "And you wouldn’t blow it all on overpriced food and shiny accessories?"

Lena gasped dramatically. "How dare you?!"

Lucas rolled his eyes and turned to walk away, but in a swift motion, Lena darted forward, slipping her hand into his pocket. Before he could react, she yanked out his coin pouch, bouncing back with a victorious grin.

"Too slow, big brother!" she taunted, jingling the pouch in front of him.

Lucas lunged for it. "Lena, give it back!"

She dodged effortlessly, laughing as she twirled away. "Nope! I am now your official financial manager!"

Lucas groaned. "This isn’t how things work!"

Lena smirked, stuffing the pouch into her own satchel. "Well, in this world, they do. Welcome to Isekai Financial Management—Lena Edition." She then tapped her chin thoughtfully. "Now, where shall we stay?"

Lucas gave her a flat look. "You mean where I paid for us to stay."

"Details, details," Lena waved him off. "C’mon, let’s find somewhere nice! We have money now!"

After wandering through town for a while, Lena finally stopped in front of a well-kept inn with a warm, inviting glow. A wooden sign hanging above the entrance read The Velvet Hearth. Unlike the rowdier establishments they had passed, this one exuded an air of sophistication—elegant lanterns lined the doorway, and the scent of freshly baked pastries mixed with fine herbal tea drifted from within.

Lucas eyed it skeptically. "Looks expensive."

Lena smirked. "Which is why it’s perfect. We can afford it."

Lucas muttered, "You mean I can afford it."

Ignoring him, Lena confidently pushed open the door.

The inside was even cozier than expected. Plush chairs, polished wooden floors, and a large hearth crackling with gentle flames made the place feel more like a noble’s retreat than a simple inn. A few well-dressed travelers sat in the common area, sipping drinks and chatting softly.

Then, the moment she appeared, Lucas felt it.

A subtle yet dangerous shift in the atmosphere.

---

The woman behind the counter was dangerous—not in a combat sense, but in a way that sent warning bells ringing in Lucas’s head. She was a statuesque beauty, probably in her late thirties, with wavy chestnut hair cascading over her shoulders. Her emerald-green eyes carried a knowing glint, and her lips curled into a subtle smirk the moment she laid eyes on Lucas.

She was, in every definition, a certified MILF.

And that was a problem.

Because the moment Lucas stepped inside, his passive skill triggered.
