Ultimate Spin System: Ero Spin?-Chapter 112 - Divine Warning

Lucas swallowed, forcing himself to steady his breathing. His fingers clenched around the sheets, his body still trembling from whatever had just happened. The presence had been real. It wasn’t just a nightmare.

And the system had been suspiciously quiet.

Lucas exhaled sharply, pushing himself up from the bed.

"Damn it..." he muttered under his breath.

[Ding!]

He barely suppressed a flinch.

[ Finally awake? Took you long enough, Host. You were practically choking in your sleep. ]

Lucas shot the floating text a glare. "You knew something was happening, didn’t you?"

[ Oho? What an accusation! But yes, I did notice. However, I found it more entertaining to see how you’d react. ]

Lucas clenched his jaw. "What the hell was that?"

[ That, dear Host, was someone—or something—probing your existence. And given that it whispered ’Intruder’ in such a dramatic fashion, I’d say it wasn’t exactly a welcoming committee. ]

Lucas exhaled, rubbing his temples. "Great. Just great."

[ But here’s the real kicker—Zareth knows you’re here. ]

Lucas’s blood ran cold.

He turned sharply toward the floating text. "What?!"

[ Oh, don’t be so dramatic. He doesn’t know exactly who you are, just that you exist. ]

Lucas’s breathing quickened. His pulse thundered in his ears. "You’re telling me a god of darkness knows I exist and you didn’t think that was worth warning me about sooner?"

[ Relax, Host. It’s not a problem unless you become important. ]

Lucas let out a bitter laugh, running a hand through his hair. "Not a problem? Not a problem?! You just said Zareth, one of the four gods, is aware of me!"

[ And? He’s got bigger things to worry about. Unless you do something incredibly stupid, like, oh, I don’t know... start influencing world events, gain a massive following, or—heaven forbid—mess with divine artifacts, then you’re just another ant crawling in the dirt. ]

Lucas gritted his teeth. "I have twenty-seven days until I can use the isekai portable portal to leave. You’re telling me I just have to stay out of trouble until then?"

[ Bingo. Try not to be memorable, and you’ll be fine. ]

Easier said than done.

Lucas leaned back against the headboard, his heart still pounding. 𝒻𝑟ℯℯ𝑤𝑒𝑏𝑛𝘰𝓋𝑒𝓁.𝒸𝑜𝘮

The system’s attitude pissed him off, but the logic made sense. Zareth had only noticed him now. That meant he hadn’t fully drawn the god’s attention yet. If he laid low and avoided anything major, he could still escape without incident.

But the whisper... that presence in his room...

That meant something—or someone—was already looking for him.

And that terrified him more than anything.

Lucas exhaled through his nose, pushing down the anxiety clawing at his chest. He needed a plan. He needed to stay invisible.

For the next twenty-seven days, survival wasn’t just about monsters, adventurers, or nobles.

It was about avoiding the gaze of something far worse.

A god.

Lucas took a deep breath, trying to calm the rapid thudding in his chest. His mind was racing, piecing together the implications of what the system had just said.

"How?" he asked, his voice sharper than he intended. "How does Zareth even know I exist?"

The system hummed, as if amused.

[ Oh? Took you long enough to ask. Well, Host, it’s simple. You’ve killed before. ]

Lucas stiffened.

His throat went dry, and for a moment, he couldn’t breathe. His mind dredged up a memory he had buried long ago—the moment when his actions had led to someone’s death.

No. He hadn’t murdered anyone. Not directly. But it didn’t change the outcome.

He swallowed hard. "...That doesn’t make sense. I didn’t kill anyone here."

[ Doesn’t matter. Your soul has already been stained by human blood. That leaves a mark. One that certain... entities can detect. ]

Lucas clenched his fists, his knuckles turning white. "So you’re saying Zareth noticed me because of something that happened before I got here?"

[ Bingo! And let’s be honest, Host, it’s not like you’re a pure little saint. A god like Zareth thrives on the energy of death, chaos, and destruction. People like you? You shine like a beacon in his domain. ]

Lucas shut his eyes for a moment, exhaling through his nose. His thoughts were a mess, but he forced himself to focus.

"So that’s why he sensed me," he muttered. "Because of that."

[ Ding ding ding! Give the man a prize. ]

Lucas gritted his teeth. "Damn it."

He had spent so much time worrying about surviving this world, about monsters and dungeons and quests—he hadn’t even considered that something from his past life could follow him here.

And now, a god of darkness had noticed him.

His pulse quickened again, but a new fear clawed at his chest—Lena.

His gaze snapped to the floating screen. "What about Lena? Is she in danger?"

[ Pfft. Of course not. ]

Lucas narrowed his eyes. "Why not?"

[ Because unlike you, she’s clean. A completely unremarkable, normal adventurer. Well, normal enough. She hasn’t killed in a way that leaves a mark. So, congrats, Host! You’re the only one on Zareth’s radar. ]

Lucas exhaled, tension easing from his shoulders—just a little. At least Lena wouldn’t get dragged into this.

But that meant he had to be careful. If Zareth’s attention was already on him, then every step he took from now on mattered.

Twenty-seven days.

He just had to stay out of sight, avoid unnecessary fights, and keep a low profile.

Simple.

Right?

Lucas ran a hand through his hair, his mind still trying to process everything. His past had come back to haunt him in the worst possible way. If Zareth had only sensed him because of his previous actions, then that meant... as long as he didn’t do anything drastic, he might still be able to slip away unnoticed.

Right?

Before he could fully convince himself, the system’s text flickered again.

[ Oh, and one more thing, Host. This is very important, so listen closely. ]

Lucas’s stomach tightened. "What now?"

[ Under no circumstances are you to accept any invitations from the Four Great Kingdoms to fight against the Abyss. ]

Lucas frowned. "What?"

[ You heard me. If any of those big-shot kingdoms try to recruit you for their ’holy war’ against the Abyss? Ignore them. Decline. Vanish if you have to. ]

A chill crept up Lucas’s spine. "...Why?"

[ Because, dear Host, that is when Zareth stops playing nice. ]

Lucas’s blood ran cold. His fingers curled tightly against his palm.

"...You’re saying if I join the war against the Abyss, Zareth will personally come after me?"

[ Oh, not just you. He’ll make sure your entire existence is erased in a way that makes dying seem like a pleasant afternoon nap. ]

Lucas swallowed hard.

Zareth had only sensed him because of his past. Right now, he was just another unknown piece on the board.

But the moment he aligned himself with a force that actively fought against the Abyss—against him—then Zareth wouldn’t just notice him.

He’d target him.

Lucas felt an icy weight settle in his chest. "The Four Kingdoms... they’re at war with the Abyss?"

[ Of course. It’s been that way for centuries. Some battles are big, some are small, but they’re always fighting in the background. The moment you step into that mess? You stop being an observer. You become a threat. ]

Lucas exhaled, his grip tightening. "And if I refuse? If I just stay out of it?"

[ Then, my dear Host, you might just survive long enough to use that handy little Isekai Portable Portal of yours. ]

Lucas gritted his teeth. He hated this. He hated feeling like he was walking on a razor’s edge.

But he wasn’t stupid.

If Zareth was as powerful as the system made him sound, then provoking him was suicide.

Knock. Knock. Knock.

Lucas froze.

His eyes darted toward the door.

It was already deep into the night. The sounds of the bustling city had died down, leaving only the occasional creak of wooden beams and the distant howl of the wind.

Nobody should be here.

His fingers instinctively hovered near the dagger strapped to his belt. His heart pounded.

Who the hell would visit him at this hour?

For a moment, he debated ignoring it. Maybe they’d just go away.

But then—

Knock. Knock. Knock.

Three steady raps, evenly spaced.

Persistent.

Lucas’s breath came slow and measured as he pushed himself off the bed. His fingers curled tighter around the dagger’s hilt. Carefully, he approached the door.

"...Who is it?" he asked, his voice low.

Silence.

A tense beat passed before a voice—calm, unwavering—spoke from the other side.

"I am a messenger."

Lucas’s pulse spiked.

His grip on the dagger tightened, but he forced himself to stay composed. "A messenger from who?"

A pause. Then—

"Zareth."

Cold fear slithered down Lucas’s spine.

He felt the air grow heavier, like the very room had sunk into some unseen abyss. His breathing grew shallow.

This was bad. This was very bad.

The system had just warned him.

And now, a direct messenger of Zareth was at his door.

Lucas hesitated, debating whether to open it.

But something in the air—some unnatural pull—told him that refusing would be a mistake.

With slow, cautious movements, he unlatched the door.

It creaked open.

And there, standing in the dim hallway, was a figure draped in a long, tattered cloak.

A mask—twisted and eerie—covered their face, carved with hollow, exaggerated expressions. It looked like something out of a nightmare, an unsettling blend of sorrow and mirth. The dim lantern light from the hall barely reached them, casting deep, shifting shadows along the walls.

Lucas’s stomach churned.

The masked figure bowed slightly.

"I do not know what binds you to my lord," the voice behind the mask murmured. "Nor do I seek to understand."

Their tone was neither friendly nor hostile. It was simply... neutral.

"I am merely a vessel," the figure continued. "A humble servant who carries forth the whispers of the Abyss."

Lucas exhaled slowly, his fingers still clutching his weapon. "...And?"

The masked figure tilted their head slightly, then reached into their robe.

Lucas tensed—prepared to react—until he saw what the figure withdrew.

Nothing more than an old, tattered scroll.

The figure held it up but made no move to hand it over. Instead, they spoke:

"Remain an observer. Seek wisdom. Do not cross the boundaries between worlds that were never meant to be crossed."

Lucas felt something shift in the air, as if reality itself trembled for the briefest moment.

The words echoed in his mind, carrying a weight far beyond their surface meaning.

Remain an observer.

Seek wisdom.

Do not cross the boundaries.

Lucas’s throat went dry.

The warning felt absolute.

Final.

Like a thread dangling over the edge of an abyss—one wrong step, and he would fall.

The figure let the silence stretch before taking a step back, bowing slightly once more. "The message has been delivered."

And without another word, they turned, their cloaked form dissolving into the darkness of the hallway.

Lucas stood frozen, his grip still tight on the dagger.

Only when the oppressive weight in the air began to fade did he finally move, exhaling the breath he hadn’t realized he was holding.

His heart pounded.

His skin was cold.

He shut the door quickly, locking it tight.

The system’s text flickered into view, almost smug.

[ Well, Host... congratulations. You just got your first divine warning. ]
