Investing in My Yandare Villainess Fiancée:Each Reward Fuels My Growth

Chapter 71: Investment 71: What Lies Beneath

The cellar door had always struck Elliot, as a child, as nothing more than a slightly stubborn hinge that groaned louder than the rest of the house. He’d played hide-and-seek behind it a dozen times, hidden from Mira’s toddling pursuit among sacks of grain and dust-covered wine racks, never once suspecting that the modest wooden door led to anything more significant than root vegetables and his father’s private stock of brandy.

Standing before it now, torch in hand, flanked by his father, Seria, and two of the estate’s most trusted guards, it felt like an entirely different door altogether.

"You’re certain about this," Cassian said, though the question was directed more at himself than anyone else, key already in hand.

"We have three days before that mercenary captain returns with reinforcements," Elliot said. "I’d rather know exactly what we’re protecting before then, instead of finding out the hard way in the middle of a second attack."

Cassian nodded slowly, jaw tight, and turned the key.

The lock, ancient and stiff with disuse, resisted for a long moment before giving way with a groan that seemed to echo far longer than it should have. Beyond the door, familiar shelves of preserved goods and wine gave way, at the cellar’s rear wall, to a second door Elliot had never once noticed in seventeen years of living in this house—smaller, iron-banded, etched with symbols that made the torchlight flicker strangely across their grooves.

"That wasn’t there," Elliot said slowly. "I would have noticed that."

"It’s warded," Seria said, crystal-blue eyes narrowing as she studied the symbols with clinical focus. "Concealment magic. Old. Older than anything I’ve studied at the academy."

"My father showed me this door exactly once," Cassian admitted, voice quiet, almost reverent. "The day I came of age. He told me our family had guarded whatever lay beyond it for longer than House Reingard had held any noble title at all. That it was our duty, our burden, and that I should pray to the Sky Father I never needed to open it myself."

"And now?" Elliot asked.

Cassian’s hand trembled, just slightly, as he pressed his palm flat against the door’s central symbol—a spiral, etched deep into the ancient iron, surrounded by smaller markings that pulsed faintly, almost imperceptibly, with a dim golden light.

"Now I suppose we find out exactly what kind of prayer that was meant to be."

The door groaned open, revealing a narrow stone stairway descending into darkness far deeper than the cellar above should have logically allowed. Cold air rushed up to meet them, carrying with it a faint, unmistakable hum—not sound, exactly, but something felt more than heard, a vibration that seemed to settle directly into Elliot’s bones.

"That feeling," Seria said, voice tight. "I’ve felt something like it before. In the throne room. Right before Entoma’s true form emerged."

"Primordial energy," Elliot murmured, the old man’s words from the farmland dimension echoing unbidden in his memory. Successor of Skion. "It’s the same kind of presence."

They descended slowly, torchlight throwing long, shifting shadows across walls carved with the same spiraling symbols as the door above, growing denser and more intricate the deeper they went. Elliot counted nearly two hundred steps before the stairway finally opened into a wide, circular chamber, its domed ceiling lost somewhere in shadow far above the torch’s meager light.

At the chamber’s center, resting atop a simple stone pedestal untouched by dust or time despite what must have been centuries of isolation, sat a small, unassuming object—a shard of pale, crystalline stone, no larger than a clenched fist, pulsing faintly with the same golden light that had marked the door above.

"That’s it?" one of the guards said, unable to keep the disbelief from his voice. "That’s what an entire secret organization is willing to go to war over?"

"Appearances," Seria said slowly, echoing Mary’s own words from weeks earlier without quite realizing it, "can be deceiving."

Elliot approached the pedestal cautiously, torch held low, every instinct screaming at him to proceed with more caution than curiosity. As he drew closer, the shard’s pulse quickened, golden light brightening in what felt disturbingly like recognition.

[The Fragment of Skion has detected a compatible bloodline signature.]

[Warning: Direct contact with an unstable primordial artifact carries significant risk. Proceed with extreme caution.]

"Elliot?" Seria’s voice carried a note of alarm as the notification flickered across his vision, his expression clearly shifting in response to something only he could see. "What is it?"

"It knows me," he said quietly, staring at the pulsing shard. "Somehow, it already knows me."

Cassian stepped closer, studying the fragment with an expression caught somewhere between awe and dread. "My father called it a sleeping thing. Something that needed to be guarded, never woken. I always assumed that was simply an old man’s superstitious phrasing."

"I don’t think it was," Elliot said.

"Should we be doing this now?" one of the guards asked carefully, glancing between the pulsing shard and the narrow stairway behind them, as if half-expecting the mercenaries to come pouring down it at any moment. "Perhaps it would be wiser to wait. Gather more information first."

"We don’t have that luxury," Cassian said grimly. "Not with three days on the clock and an organization that already knows exactly what’s down here."

"Then we do this carefully," Seria said, though her hand had already found Elliot’s free arm, fingers tightening with unmistakable tension. "Not recklessly."

Elliot glanced back at her, at the fear plainly visible beneath her composed exterior, and felt something in his chest tighten in response. "I’ll be careful."

"You said that before you crushed two vitality potions with your teeth while your heart was in pieces," she said flatly.

"That’s different."

"Is it?"

He reached out slowly, fingers hovering just above the shard’s pulsing surface, hesitating for one long, uncertain moment.

"Elliot, wait—" Seria started, but it was already too late.

The instant his fingertips brushed the crystal’s surface, the entire chamber erupted into blinding golden light, the hum that had followed them down the stairway swelling into a deep, resonant chord that seemed to shake the very foundation of the estate above them.

And somewhere, deep within that light, Elliot heard a voice—ancient, patient, and unmistakably familiar.

"Ah," the old farmer’s voice said, warm with something that might have been relief. "There you are, child. I was beginning to wonder how long it would take you to find your way back to me."
