Isekai Student Historian: Chapter 09

Chapter 9: The Fatal Funnel and the Aetheric Toll

The northern Wildlands at night were a suffocating labyrinth of twisted roots and absolute, pitch-black darkness. The air tasted of ash and copper, heavy with the toxic runoff of the corrupted World Tree.

Yet, as John Fallon and his strike team moved silently through the dense underbrush, they could see perfectly.

They were enveloped in a shimmering, translucent sphere. From the outside, anyone — or anything — looking at them would see only a void, a patch of darkness indistinguishable from the rest of the dead forest. But inside the bubble, a soft, ambient glow illuminated the ground, revealing trip-roots and jagged rocks.

“I don’t understand,” Alice whispered, stepping gracefully over a glowing purple puddle of moss. She looked around the interior of the dome. “Shadow magic is forbidden in the capital because it is the art of blinding and darkness. Why is it so bright in here?”

At the rear of the formation, Marund chuckled, a dry, raspy sound. He leaned on his wooden staff, his hands glowing with a faint, complex weave of mana.

“The capital fears what it does not study, little sword,” the old mage rasped. “Shadow magic is not the creation of nothingness. True shadow arts require the manipulation and displacement of light. To cast a perfect sphere of darkness outward to hide us from the beasts, I must pull all the ambient light inward. We walk in the concentrated light that I have stolen from the forest.”

John nodded approvingly, adjusting the canvas strap of his messenger bag. “Conservation of energy. Very efficient, Marund.”

“Hush,” Kalinda growled from the front of the formation, dropping into a low crouch. “We are here.”

The team halted. They had reached the edge of a massive, sunken depression in the earth. At the center of the valley, rising out of the mist, was the dead World Tree. Attached to its base was the Aetheric Parasite — a throbbing, fleshy mass the size of a cottage, actively pumping black sludge into the soil.

And pacing fiercely in front of it was the corrupted guardian.

Up close, the fifteen-foot bear was a localized nightmare. Thick plates of crystallized black sludge armored its chest, back, and skull like jagged obsidian. Spikes of bone protruded from its spine, and its multiple purple eyes darted through the gloom, searching for prey.

Kalinda bared her teeth, her grip tightening on her massive iron broadsword. She tensed her legs, ready to launch herself down the embankment.

“Hold on,” John commanded, grabbing her shoulder. “We don’t charge. Remember the training. Squad tactics. Look at the terrain.”

John pointed down the slope. Two colossal roots from the murdered World Tree jutted out of the earth, creating a narrow, ten-foot-wide passageway that led directly to the parasite.

“The fatal funnel,” Alice murmured, her eyes lighting up with realization.

“Exactly,” John said, pulling a dense, foil-wrapped protein block from his bag and taking a massive bite, preemptively fueling his system. “If we fight it in the open, it will use its massive weight to flank and crush us. We force it into that gap between the roots. Kalinda, you are the Anvil. You plant your feet in that gap and you do not let it pass. Alice, you take the right root, stay out of reach, and slice the joints. I will be the Hammer.”

“And me?” Marund asked.

“Keep the shadows thick around the edges,” John said, tossing his wrapper into the dirt. “Don’t let any smaller beasts crash our party. Go.”

They moved with practiced, terrifying efficiency. Kalinda slid down the embankment, taking her position squarely between the two massive roots. She slammed the flat of her broadsword against her iron bracer. The ringing CLANG echoed through the dead valley like a thunderclap.

The monstrous bear snapped its massive head toward the sound. It let out a roar that shook the leaves from the canopy and charged, moving with terrifying speed for something so massive. It barreled straight into the narrow passageway between the roots.

“Hold!” Kalinda screamed, bracing her boots deep into the mud.

The bear slammed into her sword guard. The impact sounded like a siege ram hitting a castle gate. Kalinda was pushed back two feet, her boots carving trenches in the earth, but the Anvil held. The beast snapped its jaws, trying to bring its massive, armored claws down on her head, but the narrow roots restricted its movement, preventing it from swinging wide.

From atop the right root, Alice dropped like a silver blur. Her red-gold rapier flashed in the dark, surgically piercing the unarmored flesh behind the bear’s knee. The beast roared in pain, shifting its weight, but Alice was already gone, vaulting back into the shadows.

“Its armor is too thick for my sword!” Kalinda yelled, straining against the immense weight of the monster.

“I’ve got it!” John yelled, stepping to the mouth of the funnel. He didn’t use a chant. He accessed his core, bypassing the world’s arcane rules and applying pure, brute-force physics.

Thermal shock, John thought.

He inverted the atmospheric pressure in front of him, instantly stripping the heat from the air. A blast of hyper-compressed, absolute-zero wind slammed into the bear’s thick chest plate. The dark sludge instantly frosted over, freezing solid in a fraction of a second.

Before the bear could even react to the cold, John shifted his stance. He thrust his right hand forward. A concentrated beam of superheated plasma erupted from his palm, striking the exact same spot on the frozen armor.

The physical toll of channeling absolute zero and extreme heat back-to-back hit John like a freight train. His vision tunneled, and a wave of agonizing nausea ripped through his stomach. His hands began to shake violently as his body cannibalized its own caloric reserves to sustain the rapid, violent shift in elemental energy.

He stumbled, dropping his heavy canvas messenger bag into the mud. Panting heavily, John dropped to one knee, desperately needing fuel.

Alice, seeing her commander falter, darted away from the beast. “John, I have you!” she yelled, remembering his previous instructions about his need for food.

She slid into the mud next to him and ripped open the flap of his canvas bag, thrusting her hand inside to grab the meats and cheeses she had watched him pack.

She frowned. She dug her hand deeper.

“John…” Alice said, her voice laced with sudden panic. “It’s empty. There’s nothing in here. It’s just a canvas sack!”

“Just focus on the joints!” John gasped. He reached over, shoved his hand into the entirely unremarkable, empty canvas bag and pulled out an entire, massive wheel of smoked cheese.

Alice’s jaw dropped in sheer bewilderment.

John took a massive, unceremonious bite of the cheese rind, swallowing heavily. The dense fats and proteins hit his system, stabilizing his mana core. He stood back up, wiping his mouth.

“Kalinda, strike the chest!” John roared.

The barbarian didn’t hesitate. She ducked under a wild swipe of the bear’s claws, rotated her hips, and drove the heavy iron pommel of her broadsword directly into the center of the monster’s chest plate.

Because of John’s magic, the armor wasn’t just weakened; it was structurally destroyed.

The impenetrable sludge armor shattered like cheap glass, exploding outward in a shower of black shards.

With its chest completely exposed, Kalinda roared, reversing her grip and driving her blade deep into the beast’s heart. At the exact same moment, Alice launched off the side root, her rapier flashing forward like a needle of light, piercing directly through the monster’s glowing purple eye and into its brain.

The massive bear stiffened, let out one final, gurgling sigh, and collapsed into the mud, dead.

Silence fell over the valley, save for the heavy, exhausted panting of the strike team.

“Marund!” John called out, leaning against the damp bark of the World Tree. “Cut the leyline!”

The old shadow mage stepped out of the gloom, walking past the dead bear. He placed his glowing, shadowed hands directly onto the massive roots of the tree, beneath the throbbing, fleshy parasite. With a sharp twist of his wrists, Marund inverted the flow of ambient light and dark mana, aggressively severing the parasite’s connection to the earth’s natural magic.

The fleshy node shrieked — a high, piercing sound of pure static. It began to wither instantly, turning gray and flaking away into harmless ash. The heavy, toxic smell in the air immediately began to dissipate.

“It is done,” Marund breathed, stepping back, looking completely exhausted. “The rot is severed. The forest will heal.”

Kalinda pulled her sword from the beast, wiping the black blood on the grass. She looked at John, a massive grin splitting her scarred face. “The Hammer strikes true! We killed a demon of the deep woods! They will sing songs of this night!”

Alice sheathed her rapier, walking over to John. She looked at the dead beast, then at the half-eaten wheel of cheese still in John’s hand.

“How did you break its shell without touching it?” Alice asked, her aristocratic composure completely replaced by intense curiosity. “And more importantly, what kind of legendary spatial artifact is that dirty canvas bag?”

“I’ll tell you about the bag later,” John deflected, taking another bite of cheese. “As for the armor, it’s a basic principle of physics from my homeland called thermal shock.”

He pointed to the shattered black crystals on the ground. “When you freeze something that hard, you are pulling all the heat out of it, making the molecules lock together tightly. If you then immediately blast it with extreme heat, the outside tries to expand instantly, but the inside is still frozen solid. It’s like… imagine having freezing cold hands in the middle of winter, and plunging them directly into boiling water. But a thousand times worse. The material physically cannot handle the stress of expanding and contracting at the same time, so it simply shatters.”

Kalinda crossed her arms, nodding slowly as if she understood the molecular physics of thermal expansion. “Ah. The hot-cold smashing technique. Very wise.”

“Yes,” John sighed. “The hot-cold smashing technique.”

He tossed the rest of the cheese back into his bag, which swallowed it without a bulge. Then, to the absolute bewilderment of his team of legendary warriors standing over the corpse of a slain nightmare beast, John pulled out a small, leather-bound notebook and a piece of charcoal.

He began writing furiously, completely ruining the epic, heroic atmosphere.

“Alright,” John said, shifting seamlessly into his corporate CEO cadence. “This confirms our immediate supply chains are safe, and the timber operations can resume in the outer woods by Monday. Excellent work, team.”

“Are… are you taking notes on the battle?” Alice asked, blinking in confusion.

“No,” John said, staring intently at the charcoal scratchings. “I’m restructuring our immediate industrial priorities. Tomorrow morning, Jake and I are drawing up blueprints for a water-powered pulping mill by the river. We are going to mash scrap wood into a soft, fibrous paste.”

Kalinda frowned. “Why do we need soft wood paste? Not to eat!”

John looked up from his notebook, his blue eyes dead serious.

“Because we are inventing mass-produced toilet paper,” John declared with absolute, unyielding conviction. “I refuse to use a damp sponge on a stick for another week. We march at dawn.”
