My Class Is Serial Killer and the System Wants Me to Embrace

First Blood (But Not the Kind You Think)

The dungeon entrance looked like a tear in reality.

It shimmered in the middle of Franklin Community Center's basketball court—a vertical slash of purple-black energy that hurt to look at directly. According to the sign posted by the city, this was a Level 1-3 dungeon that had manifested two weeks ago. "Goblin Warren" was its official designation. Perfect for newly Awakened parties.

"Holy shit, it's actually real," Tyler breathed, staring at the portal with wide eyes.

We'd all seen dungeons on TV and in videos, but standing in front of one was different. The air around it felt wrong—too thick, too heavy, like the atmosphere before a thunderstorm. My Predator's Eye kept trying to analyze it and failing, spitting out error messages.

Jake was practically bouncing with excitement, small flames dancing between his fingers. "Okay, so the guide said Goblin Warrens are pretty straightforward. Lots of small, weak monsters. Good for grinding basic combat experience."

"And the loot?" Sarah asked, adjusting the small backpack she'd brought. As an Enchanter, she wasn't built for combat, but she'd insisted on coming anyway.

"Mostly basic crafting materials. Goblin teeth, scraps of cloth, maybe some low-grade weapons." Jake pulled up a wiki page on his phone. "The boss is a Goblin Chief. Level 3, uses a club, has a group buff ability. We should save him for last after we clear the adds."

He'd done his research. We all had, to varying degrees. Except for Raven, who was leaning against the community center wall looking amused.

"Your friend seems pretty chill about this," Lisa whispered to me. She'd gotten over her initial disappointment about Healing and was now theorycrafting the optimal support build.

"Raven's Level 3. She's done dungeons before."

That got everyone's attention. Level 3 was significant for someone who'd only been Awakened for a few months. It suggested either regular dungeon grinding or some other source of experience.

I tried not to think about what that "other source" might be for a Shadow Class.

"Any advice?" Jake asked Raven.

She pushed off the wall and sized up our group. "Don't split up. Don't chase enemies into unexplored areas. And if something feels wrong, retreat immediately. Dungeons are predictable until they're not."

"Comforting," Tyler muttered.

"It's honest." Raven looked at each of us in turn. "This is a baby dungeon, so you'll probably be fine. But people still die in baby dungeons when they get cocky. So don't get cocky."

Jake nodded seriously, his earlier excitement tempered by the reality check. "Okay. Formation. Tyler, you're up front since you're the tankiest. Lisa, you stay in the middle to heal. Sarah, you're with Lisa. Marcus and I will be on the sides for ranged damage. Raven, you good in the back for stealth strikes?"

"Works for me."

We lined up at the portal entrance. This close, I could hear it—a low thrumming sound that seemed to resonate in my bones. The air tasted like ozone and something else. Something primal.

"On three," Jake said. "One... two... three!"

We stepped through together.

The transition was instant and disorienting. One moment we were in a basketball court under fluorescent lights. The next, we were in a cave system lit by bioluminescent fungus, the air damp and smelling of earth and rot.

[You have entered: Goblin Warren (Level 1-3)]

[Party formed: 6 members]

[Recommended party size: 3-5]

[Good luck, Awakened!]

"Six is better than five, right?" Sarah said nervously.

"More loot to split," Tyler pointed out, already moving forward. His Brawler instincts were clearly kicking in—he walked with his fists raised, scanning for threats.

We didn't have to wait long.

The first goblin appeared around a bend in the tunnel—about three feet tall, gray-green skin, yellow eyes, and wickedly sharp teeth. It wore a ragged loincloth and carried a rusty knife that was probably more tetanus risk than actual weapon.

[Goblin Scout - Level 1]

[Threat Assessment: Minimal]

[Weakness: Low health, poor defense, susceptible to fire]

"I got this!" Jake shouted, and launched a fist-sized fireball.

His aim was terrible. The fireball sailed past the goblin and splattered against the cave wall, leaving a scorch mark.

The goblin shrieked and charged at Tyler.

"Shit! Tyler, incoming!" Jake prepared another spell.

Tyler didn't need the warning. He met the goblin's charge with a straight punch that caught it in the chest. There was a sound like a baseball bat hitting a watermelon, and the goblin flew backward, hit the cave wall, and slumped down, clearly dead.

[Goblin Scout defeated!]

[Experience gained: 5 XP (split among party)]

[Tyler Moss gained: 1 XP]

"Holy crap," Tyler stared at his fist. "I killed it in one hit."

"It was only Level 1," Raven pointed out. "And you're optimized for Strength. Don't let it go to your head."

But Tyler was grinning ear to ear, and honestly, I couldn't blame him. There was something visceral about that first kill—even if it was just a dungeon monster. Proof that we were really Awakened, really capable of fighting.

We moved deeper into the warren. The tunnels branched and reconnected in a maze-like pattern, but Jake had downloaded a map from the wiki. We encountered goblins in small groups—two or three at a time—and quickly fell into a rhythm.

Tyler would charge in and draw aggro. Jake would throw fireballs (his aim was improving). I'd flank and use my higher Agility to get critical hits from behind. Lisa would heal anyone who took damage, though so far the goblins were too weak to do much harm. Sarah stayed in the middle, observing everything, occasionally making notes about potential enchantment applications.

And Raven... Raven disappeared into the shadows and occasionally a goblin would just drop dead with a surprised expression, a knife wound in its back.

After the fifth group of goblins, I checked my experience.

[Experience: 15/100]

Fifteen experience points. At this rate, I'd need to kill dozens more goblins to reach Level 2. It was slow. Grindy. Exactly what everyone said early-level dungeon running would be like.

But it was also... kind of fun? There was something satisfying about working together, about the tactical problem-solving, about watching Jake's fireballs get more accurate with each attempt.

For a little while, I could almost forget about the quest timer counting down in my peripheral vision.

Almost.

"Break time," Jake called after we cleared another group. We'd been in the dungeon for about forty minutes, and everyone was starting to feel the strain. Dungeons were physically exhausting in a way that normal exercise wasn't—the System enhanced our bodies but also pushed them harder.

We found a wider section of tunnel and collapsed against the walls. Lisa passed around water bottles. Sarah shared granola bars she'd brought.

"This is actually pretty cool," she said between bites. "I mean, scary and gross, but cool. We're fighting actual monsters."

"And getting actual experience," Jake added. He'd gained two full levels already, hitting Level 3. His Flame Mage build was optimized for this kind of grinding. "At this rate, I'll be Level 5 by the end of the week."

Tyler flexed his arms, where a faint glow indicated new stat points being distributed. "My Strength just hit 20. I can probably punch through a car door now."

"Please don't test that on my mom's car," Jake said.

Everyone laughed. It felt normal. Human. Like we were just kids on an adventure.

Then Raven stiffened, her hand going to the knife at her belt.

"Something's wrong," she said quietly.

The laughter stopped. "What do you mean?" I asked.

"The dungeon. It's too quiet. We should be hearing more goblins by now—they live in groups. But listen."

We listened. She was right. The ambient noise of the dungeon—distant skittering, echoing shrieks—had gone silent.

[Warning: Dungeon boss has detected intruders]

[Goblin Chief is hunting your party]

"Oh fuck," Jake breathed.

The ground trembled. From deeper in the warren came a roar that made the earlier goblin shrieks sound like mouse squeaks.

"Boss fight?" Sarah squeaked.

"Boss fight," Raven confirmed, already moving to a defensive position. "Everyone get up. Formation. Now."

We scrambled to our feet just as the Goblin Chief rounded the corner.

It was massive—at least seven feet tall, heavily muscled, with scars crisscrossing its gray-green hide. It wore crude bone armor and carried a club that looked like it was made from a small tree trunk. Behind it, a dozen regular goblins swarmed, their eyes glowing with the same red tint as their chief.

[Goblin Chief - Level 3 Elite]

[Threat Assessment: Significant]

[Special Ability: Battle Frenzy - All nearby goblins gain +20% attack and speed]

[Weakness: Slow attack speed, vulnerable after missed swings]

"Tyler, hold the chief! Everyone else focus fire on the adds!" Jake's voice cracked slightly, but his tactical sense was sound.

Tyler charged forward with a roar that was probably supposed to be intimidating but came out more like a teenager's voice crack. Still, his Brawler skills kicked in. He met the Goblin Chief's first swing with a dodge, then landed a solid punch to its ribs.

The chief barely flinched. It swung again, and this time Tyler wasn't fast enough. The club caught him in the shoulder, sending him spinning.

[Tyler Moss has taken 35 damage]

[HP: 65/100]

"Tyler!" Lisa's hands glowed with healing light as she channeled her Healer abilities.

Meanwhile, the goblin adds were charging at the rest of us. Jake's fireball caught two of them, the flames spreading between them. I drew the cheap knife I'd bought yesterday—not the one from last night, that one was safely hidden at home—and activated my Rogue skills.

[Stealth Strike ready]

[Target: Goblin Warrior]

I moved without thinking, muscle memory and System assistance blending together. My blade found the gap between the goblin's ribs. The creature shrieked and collapsed.

[Goblin Warrior defeated!]

[Experience gained: 3 XP]

Two more goblins rushed me. I backed up, using my Agility to stay just out of reach of their knives. One of them overextended, and I punished it with a strike to the throat.

Another kill. Another burst of experience.

This was different from planning to murder Raymond Booker. These were monsters. Dungeon spawns. Not real people with lives and families.

But my Class skills activated the same way. The same cold analysis. The same efficient lethality.

Was this what it would feel like? When I finally crossed that line?

A shriek pulled me back to the present. Sarah had been backed into a corner by three goblins. She had no combat abilities—Enchanters were pure support.

"Sarah!" I sprinted toward her, but Raven was faster.

She materialized from the shadows behind the goblins, her knives flashing. Three quick strikes, three falling bodies. She grabbed Sarah and pulled her back toward the center of our formation.

"Stay with Lisa!" Raven commanded.

The fight was chaos. Jake's fireballs flew everywhere—his mana had to be running low. Tyler was trading blows with the Goblin Chief, taking damage but dishing it out in return. Lisa was alternating between healing Tyler and throwing weak light-based attacks at any goblin that got too close.

And me? I was dancing between targets, using my Agility to strike and fade, racking up kills through opportunistic strikes rather than raw power.

It felt natural. Instinctive.

It felt like what I was built for.

[Predator's Eye has reached Level 2]

[New feature unlocked: Weak Point Identification]

Suddenly I could see them—glowing spots on each goblin indicating optimal strike locations. Throats. Hearts. Joints. Places where a precise strike would end a fight instantly.

I used it. Of course I used it. This was a dungeon fight. These were monsters.

But a small voice in the back of my head whispered: This is practice. For when the monsters look human.

The Goblin Chief roared, its Battle Frenzy intensifying as it took more damage. Tyler was flagging, his HP dropping despite Lisa's healing.

"We need to finish this!" Jake shouted, gathering power for what looked like a bigger spell.

"Everyone clear the boss!" Raven ordered. "Jake's going big!"

We scattered. Tyler rolled away from the chief. The remaining goblins—only three left—turned toward Jake, recognizing the threat.

Too late.

Jake released a cone of flame that engulfed the Goblin Chief and its remaining minions. The cave filled with the smell of burning flesh and the sound of dying shrieks.

When the flames cleared, the Goblin Chief was on its knees, charred and smoking but still alive.

[Goblin Chief HP: 45/300]

"Finish it!" Jake gasped, clearly exhausted from the mana expenditure.

Tyler limped forward and brought both fists down on the chief's skull in a double-hammer strike. There was a sickening crunch, and the massive goblin toppled forward.

[Goblin Chief defeated!]

[Dungeon cleared!]

[Bonus experience awarded for first clear]

[Total experience gained: 85 XP]

The notifications cascaded through my vision. Experience. Loot. Achievement unlocks. The standard System rewards for completing a dungeon.

But all I could focus on was the feeling in my chest.

Satisfaction. Pride. The rush of victory.

I'd killed at least eight goblins today. Ended eight lives, even if they were monster lives.

And it had felt good.

[Serial Killer Class resonance detected]

[Note: Combat against sapient beings increases Class understanding]

[Skill development accelerated]

I stared at the notification, my blood running cold.

The System had noticed. It was learning from this. Taking my dungeon combat experience and feeding it back into my Serial Killer Class.

Even here, even fighting monsters instead of humans, I was still being shaped into what the System wanted me to become.

"Marcus? You okay?" Raven appeared beside me, concern in her eyes.

I looked at her and knew she understood. She could see it in my expression.

"Yeah," I lied. "Just tired."

But I wasn't tired. I was terrified.

Because killing those goblins had been easy.

And some part of me had enjoyed it.

[Quest Timer: 27 days, 10 hours, 47 minutes remaining]
