The System’s Primal Heir

Episode 10: The Serpent’s Nest

"He thinks a scrap of paper and an old knife are enough to rattle me," Leo said, his fingers tightening around the silver hilt of the dagger.

The metal groaned under his grip, the silver warping as a surge of Primal mana traveled from his palm into the blade. Behind him, the charred skeleton of his childhood home stood as a jagged monument to Marcus’s cowardice, the embers still glowing like the eyes of a dying beast.

"He isn't just rattling you, Leo," the Ancient Echo’s voice resonated from the shadows at his feet. "He is inviting you to the slaughter."

"Then I’ll make sure I’m the one holding the cleaver," Leo replied, his gray, stone-like skin smoothing over as he forced his form back into a human shape.

He tucked the warped silver dagger into his belt, the blade a bitter reminder of the night his brother had first tried to end him. The city lights flickered in the distance, dominated by the towering black monolith of the Thorne Guild Headquarters.

"The ring was the only thing our mother left behind," Leo muttered, his eyes fixed on the distant skyscraper. "If Marcus has it in the vault, I’m taking it back."

"The vault is the least of your concerns," the Echo warned. "The mana signature radiating from that building is... foul."

"I don't care how it smells," Leo said, stepping out of the ash. "I need a way inside, and I need a skin that can bypass an S-Rank scanner."

He moved toward the main thoroughfare, his shadow stretching toward the city like a hungry predator. He waited in the darkness of an alleyway near the guild’s logistics hub, his eyes scanning the workers as they ended their shifts.

"That one," Leo whispered, pointing to a man in a high-collared officer’s uniform. "He has the clearance of a Senior Administrator."

"Logistics Officer Silas," the Echo noted, the System’s interface displaying the man’s stats in a dim red glow. "His mana signature is weak, but his access is absolute."

"Perfect," Leo said, his shadow detaching from his feet and sliding across the pavement like a serpent.

The man didn't even have time to scream before the darkness pulled him into the alley. Minutes later, a man who looked exactly like Silas stepped out into the light, adjusting his collar with a cold, practiced grace.

"The resonance is holding," Leo said, testing Silas’s vocal cords. "How long do I have?"

"The 'Identity Mimicry' will last three hours, provided you do not engage in heavy combat," the Echo replied.

Leo walked toward the Thorne Guild HQ, his heart a block of ice as he approached the main security perimeter. He tapped his stolen ID card against the scanner, holding his breath as the blue light swept over his retinas.

"Late night, Silas?" the guard grunted, the heavy pneumatic doors hissing open.

"Marcus is in a mood," Leo replied, his voice a perfect, bored drone. "He wants a full audit of the sub-basement inventory before morning."

"Better you than me," the guard laughed, waving him through. "The air down there gives me the creeps."

Leo didn't respond, his boots clicking sharply against the sterile white tiles as he navigated the labyrinthine corridors. He bypassed the executive elevators, heading instead for the service stairs that led to the restricted archive levels.

"The mana density is increasing," the Echo whispered. "We are approaching the source of the rot."

"I can feel it in my teeth," Leo said, his borrowed eyes narrowing. "It smells like blood and ozone."

He reached a reinforced steel door marked with the Thorne family crest—a serpent coiled around a silver sword. He used Silas's high-level clearance to override the lock, the door sliding open with a soft, mechanical whine.

"This isn't an archive," Leo said, stepping into a room filled with rows of glowing glass canisters.

Inside the canisters, a thick, viscous liquid pulsed with a dim, sickly light. Tubes ran from the ceiling, pumping the fluid into large, industrial-sized vats that hummed with a low-frequency vibration.

"They are farming it," the Echo noted, its voice dripping with a dark, clinical fascination. "This is refined mana, Leo, but the source is biological."

"What do you mean biological?" Leo asked, walking toward a terminal that sat on a nearby desk.

"Look at the labels on the vats," the Echo commanded.

Leo leaned in, his blood running cold as he read the small, etched plates. They weren't labeled with monster types; they were labeled with human ranks: E-Rank, D-Rank, and 'Discarded.'

"These are hunters," Leo whispered, his hands beginning to shake. "They aren't just missing; they’re being used as fuel."

"The Thorne family legacy is built on a slaughterhouse," the Echo said. "They drain the weak to power the strong."

"I need to find the logs," Leo said, his fingers flying across the holographic keyboard as he bypassed the encryption layers.

The files were encrypted with a blood-lock, but the Primal System within Leo hummed, a red needle of mana extending from his fingertip to trick the sensor. The screen flickered to life, displaying a list of 'Processed Materials' spanning the last twenty years.

"Subject 402: Mana extraction successful. Source: E-Rank. Status: Expired," Leo read aloud, the words tasting like ash.

"Search for the date of the hospital fire," the Echo urged.

Leo’s breath hitched as he scrolled back through the years, his eyes scanning the names of the 'processed.' He reached a section marked 'High-Yield Assets,' his vision blurring as he saw a familiar name at the bottom of the ledger.

"It can't be," Leo gasped, his borrowed face contorting in horror.

"The dates match, Leo," the Echo said, its voice sounding almost sympathetic.

Leo stared at the screen, the red light of the terminal reflecting in his wide, unblinking eyes. He saw his mother’s name, typed in a cold, clinical font next to a series of extraction statistics that defied human morality.

"Subject: Elena Thorne," Leo whispered, his voice a hollow ghost of itself. "Status: Processed."

"She didn't die in a fire," the Echo noted. "She was the first successful harvest of the Thorne bloodline."

"They used their own mother as a battery?" Leo roared, his rage finally shattering the Silas disguise.

The gray, stone-like texture of his Primal form erupted through the skin of the logistics officer, his uniform shredding as his muscles expanded. He slammed his fist into the terminal, the holographic screen exploding into a shower of sparks and glass.

"I’m going to tear this building down with my bare hands," Leo screamed at the ceiling.

"Intruder in the lower archives!" a voice boomed over the intercom, the alarm klaxons beginning to wail. "Sector 4 breach! Activate the suppression field!"

The doors to the archive burst open, and a squad of elite Thorne guards rushed in, their mana-blades glowing with a lethal blue light. They stopped in their tracks, their eyes widening as they saw the monstrous entity standing amidst the ruins of their secret.

"Who are you?" the lead guard shouted, his voice cracking with terror.

Leo turned his head slowly, his eyes burning with a deep, predatory crimson that seemed to swallow the room’s light. He held up the silver ring he had found sitting in a velvet box on the desk—the only piece of his mother that remained.

"I'm the failure that came back to format the system," Leo said.

"Kill it! Don't let it reach the upper floors!" the guard screamed, charging forward with his blade raised.

Leo didn't even flinch, his shadow rising up from the floor like a tidal wave of ink and teeth. He looked at the mangled terminal one last time, the name of his mother still burned into his retinas.

"How many of us did you kill to make Marcus a King?" Leo asked.
