Hunger.

  Arin had felt it before. The slow drain of essence, and the growing sluggishness in his mass, but never like this. Three days of careful rationing, of passing up smaller prey to avoid unnecessary risk, had brought his essence dangerously low.

  [ Current Essence: 12/100 ]

  The notification pulsed at the edge of his awareness like a warning bell. Twelve percent. Less than half of what he'd maintained comfortably over the past week. If it dropped much lower, Arin wasn't sure what would happen. Would he lose consciousness? Lose the sapience that made him more than just a mindless slime?

  I can't let it get that low. I need to hunt. I need to feed.

  The game trail he'd discovered four nights ago had become familiar territory. Arin had spent hours watching it from the safety of the trees, learning its rhythms. Deer used it in the early morning. Smaller creatures—rabbits, raccoons—traveled it at dusk. And the boars came at night, rooting along its edges where the soil was soft and rich with grubs.

  Tonight, Arin was waiting.

  He'd positioned himself in an old oak that stretched over the trail, its thick branches providing perfect cover about fifteen feet above the ground. The branch he'd chosen was sturdy, wide enough to support his mass, and positioned directly over a section where the trail narrowed between two large roots.

  A bottleneck. Levi once mentioned how they would force enemies into predictable positions. Similar to the fight where the one never left its starting spot.

  The memory was from a conversation about military tactics that Levi had been reading about. Arin hadn't understood most of it at the time, lacking the context or awareness to appreciate strategy. But now, with his newfound sapience, the concepts made perfect sense.

  Control the terrain. Force the enemy into disadvantageous positions. Strike from unexpected angles.

  The grunting started just after full dark.

  Arin compressed his mass tighter against the branch, making himself as small and unnoticeable as possible. The sound grew louder, closer, accompanied by the familiar noise of a powerful snout tearing through earth.

  The boar emerged from the darkness like a moving shadow. It was the same one Arin had seen before—or at least, one of similar size. Level six, according to the system, with dark coarse fur and ivory tusks that caught the moonlight.

  [ Wild Boar - Level 6 ]

  The creature moved with surprising grace for something so large, its hooves finding purchase on the root-crossed trail with practiced ease. It paused about twenty feet from Arin's position, its snout lowering to investigate something in the leaf litter.

  Not yet. Wait for it to reach the bottleneck.

  Arin's core pulsed with anticipation and fear in equal measure. This was the largest prey he'd attempted. If he failed, if the boar escaped or worse—fought back effectively—he might not have the essence to recover.

  But if he succeeded...

  The boar moved forward, grunting contentedly as it found a rich patch of soil. Fifteen feet from the bottleneck. Ten feet.

  Five feet.

  The boar's head was directly beneath Arin's branch, so focused on the grubs it was unearthing that it had no awareness of the predator above.

  Now.

  Arin released his grip on the branch and dropped toward his target.

  The fall took less than a second, but Arin used that time to reshape his mass, forming the wedge that had become his most reliable weapon. The pointed edge led his descent, aimed at the boar's spine, just behind its skull where Levi had once mentioned was a vulnerable spot on most animals.

  The impact was devastating.

  Arin's wedge struck with all the force of his compressed mass falling from fifteen feet. The boar's front legs buckled, its snout slamming into the dirt with a wet thud. A squeal erupted from the creature. It was high-pitched, panicked, and nothing like its contented grunting from moments before.

  But Arin didn't relent. The moment he struck, he began to spread, his mass flowing over the boar's head and neck, seeking to engulf the creature's airways before it could recover.

  The boar thrashed, its powerful neck muscles flexing as it tried to lift its head. One tusk caught a section of Arin's mass, tearing through the gelatinous body like a knife through water.

  [ -8 Mass ]

  Pain lanced through Arin's consciousness—not physical pain exactly, but the sensation of losing part of himself, of being diminished. He compressed tighter, focusing his acidic nature on the boar's eyes, nose, and mouth.

  The boar's squeals became muffled as Arin flowed into its nostrils. The creature reared up on its hind legs, shaking its head violently, sending droplets of red slime flying into the undergrowth.

  [ -5 Mass ]

  Hold on. Just hold on.

  Arin could feel his essence draining with every second, the effort of maintaining his cohesion while under assault taking its toll. But the boar was weakening too. Its movements were becoming less coordinated, its breathing labored as Arin's mass blocked its airways.

  The creature slammed sideways into a tree, trying to crush the slime against the bark. The impact hurt, but Arin's gelatinous nature absorbed most of the force, spreading and reforming rather than breaking.

  [ -3 Mass ]

  The boar stumbled, its legs shaking. It made one final desperate charge forward, but managed only a few steps before collapsing onto its side. Its chest heaved, ribs expanding and contracting as it tried to draw air through a throat filled with acidic slime.

  Arin flowed deeper, his mass spreading throughout the boar's respiratory system. The creature's struggles weakened, then stopped entirely.

  For a long moment, Arin remained still, not quite believing it was over. Then the notifications began.

  The rush of growth was intoxicating. Arin felt his mass expand, felt the essence integrate into his core like liquid fire. The exhaustion that had plagued him for days vanished, replaced by a sense of vitality he'd never experienced before.

  I did it. I actually killed it.

  Pride warred with a hint of guilt in his consciousness, but the pride won out. This wasn't murder—it was survival. The boar would have never known Arin existed if he hadn't needed to eat. Nature was neither cruel nor kind; it simply was.

  The skill notification caught his attention.

  [ Skill Available: Charge - Tier 1 ]

  [ Accept skill? This will occupy 1 of 2 available skill slots. ]

  Charge. The boar's rushing attack.

  Arin considered it carefully. Unlike climbing, which he could already do, charging was something his slime body struggled with. He could roll quickly, could flow and reshape, but a true charge—the kind of powerful, momentum-driven attack the boar had used—was beyond his current capabilities.

  Yes. This could be useful.

  [ Skill Accepted: Charge - Tier 1 ]

  [ Charge: Compress your mass and launch forward with increased speed and impact force. Cost: 5 Essence per use. ]

  Knowledge flooded into Arin's consciousness, not words exactly, but understanding. He knew instinctively how to compress his mass in just the right way, how to build momentum, how to release it all in a devastating forward rush.

  One skill slot used. One remaining.

  Arin spent the next several minutes absorbing the last traces of the boar. When he was finished, his mass had increased substantially—he estimated he was now twice the size he'd been when he first entered the forest.

  The game trail was quiet again, as if the forest itself was holding its breath. Arin flowed off the trail and into the underbrush, seeking a tree to rest in. The adrenaline of the hunt was fading, replaced by a bone-deep satisfaction.

  He'd leveled up. He'd gained a useful skill. He'd fed himself and secured his survival for at least another week.

  Is this what it means to be a predator? This cycle of hunger, hunting, and satisfaction?

  Arin found a suitable oak with a high hollow and climbed up, his increased mass making the ascent slightly slower but no less secure. As he settled in, the forest's nighttime chorus resumed—crickets, frogs, the distant hoot of an owl.

  Sleep came quickly, and for the first time since Levi's death, Arin's dreams were not haunted by blood and betrayal, but filled instead with the simple, primal satisfaction of a successful hunt.

  ***

  The next day brought rain.

  Arin woke to the sound of water pattering against leaves, a gentle rhythm that would have been soothing if it weren't so dangerous. He pressed himself deeper into his hollow, watching as the forest floor below became slick with moisture.

  Water everywhere. This is bad.

  The rain continued for most of the day, keeping Arin trapped in his tree. He watched small streams form in the hollows between roots, watched puddles grow and merge, watched the forest transform into a glistening, treacherous landscape.

  By late afternoon, the rain had slowed to a drizzle, then stopped entirely. Arin waited another hour to ensure it was truly over before venturing out of his hollow.

  The forest felt different in the aftermath of rain. The air was thick with the smell of wet earth and growing things. Drops of water clung to every surface, catching the late afternoon sun and turning the forest into a field of diamonds.

  Beautiful, but deadly for me.

  Arin moved carefully, testing each surface before committing his weight to it. The bark was slippery, requiring more concentration to maintain his grip. He made a mental note to find shelter earlier if rain threatened again.

  As he descended toward the forest floor—kept high enough to avoid the worst of the standing water—movement caught his attention.

  Voices came.

  Human voices.

  Arin froze, every bit of his awareness focused on the source of the sound. Through the trees, perhaps fifty feet distant, he could see figures moving along a different game trail.

  There were three of them. Two humans—one male, one female—and something else. Someone else. The third figure was shorter than the humans, stockier, with a thick beard and what appeared to be metal armor that clinked softly as they walked.

  A dwarf. Levi read about dwarves from one of his books about the kingdom.

  Arin flowed along the branch to get a better view, careful to stay hidden behind the foliage. The three adventurers—for that's what they must be, with their weapons and armor and purposeful stride—were searching for something.

  The human woman knelt beside a plant, examining its leaves carefully before cutting a few stems with a small knife. She placed them in a leather pouch at her belt, then stood and continued walking.

  Gathering herbs. Levi mentioned that adventurers sometimes did that, collecting ingredients for potions and alchemists.

  The memory was bittersweet. Levi had loved reading about adventurers, about their quests to clear monster dens and help towns in need. He'd told Arin stories about famous adventuring parties, their exploits exaggerated to legendary proportions in the tales he'd found in the library.

  "Can you imagine, Arin?" Levi had said once, his voice wistful. "Going out into the world, helping people, making a real difference? That's what I want to do after graduation. Not work in some stuffy laboratory, but actually use alchemy to help people who need it."

  You never got that chance, Levi. They took it from you.

  The anger that surfaced was sudden and hot, catching Arin off guard. He'd been so focused on survival, on learning and growing stronger, that he'd almost forgotten about the three students who'd murdered his creator.

  Almost, but not quite.

  The adventurers moved on, their voices fading into the distance. Arin remained on his branch, thinking about what he'd seen.

  Other races. Other people. They come into this forest to gather herbs and possibly hunt monsters. That means there are monsters here—things more dangerous than boars and foxes.

  The thought was both frightening and exciting. Dangerous creatures meant dangerous prey, but they also meant opportunities to grow stronger, to gain new skills, to evolve.

  And if adventurers come here, that means there are towns nearby. Places where Levi's grandparents might be. Places where those three murderers might be living their lives as if they hadn't done anything wrong.

  The seed of a plan, still too vague to call a real plan, began to form in Arin's consciousness. He needed to get stronger. Much stronger. Strong enough to protect himself, strong enough to survive in a world that was clearly more complex and dangerous than the sewers and this small section of forest.

  And maybe, eventually, strong enough to find a way to honor Levi's memory. To help people, as Levi had wanted to do. Or to make those who'd killed him face justice.

  But first, survival. Always survival.

  Arin climbed down from the oak and began exploring his territory again, this time with a new awareness. The forest wasn't just his hunting ground—it was his training ground. Every creature he faced, every challenge he overcame, was preparing him for something larger.

  He just had to stay alive long enough to figure out what that something was.

  ***

  Two days after the rain, Arin encountered his first wolf.

  He'd been tracking a rabbit through the underbrush, planning his approach, when a howl split the afternoon air. The rabbit bolted immediately, disappearing into a burrow Arin had no hope of reaching.

  The howl came again, closer this time, followed by rustling in the undergrowth.

  Arin compressed his mass and climbed the nearest tree as quickly as his body would allow. He reached a branch about twelve feet up just as the wolf emerged from the bushes.

  [ Gray Wolf - Level 7 ]

  The wolf was lean and dangerous-looking, with gray fur and yellow eyes that seemed to see everything. It sniffed the air, its head turning slowly as it tracked some scent Arin couldn't detect.

  Then those yellow eyes locked onto the tree. Onto Arin.

  It knows I'm here. Can it smell me?

  The wolf circled the tree once, twice, its tail held low and its posture suggesting careful evaluation rather than immediate aggression. It was hunting, but unlike the foxes, it wasn't committing to an attack. It was assessing, calculating.

  Smart. Much smarter than the foxes or the boar.

  After a third circle, the wolf sat down at the base of the tree and looked up at Arin. The message was clear: I can wait.

  This was going to be a problem.
