CHAPTER 78: THE THREADS THAT BIND

Deep within the subterranean estate, Old Bones lay stretched across a patch of damp cavern moss, hands folded behind his head as he listened to the low, rhythmic hum of the stone walls. The cavern was quiet at this hour, broken only by the occasional drip of water echoing through the dark. His old wounds ached whenever the humidity settled heavily over the tunnels—a persistent reminder that he had lived far longer than most men ever managed to.

Tonight, however, it was not his body keeping him awake.

It was Caius.

The retired assassin had begun to face a problem he never expected to encounter again in his long life: the boy was improving too quickly.

minimal training had been required for the last dark elf criminal he had dragged into the training hall. That man had been a seasoned killer, someone who had spent decades spilling blood throughout the lower depths. He possessed experience, a ruthless instinct, and techniques that had taken him years to perfect.

Caius had dismantled him anyway.

He had watched the man's movements, studied his techniques, adapted to his rhythm, and eventually killed him with a frightening composure that left Old Bones deeply unsettled.

The real problem wasn't merely that Caius had survived. He had learned. And once Caius learned a lesson, Old Bones found it nearly impossible to use the same trick against him twice.

The old assassin rubbed his face with a scarred hand and sighed. "Where in the deep do I find someone more dangerous than a seasoned killer?"

He opened his eyes, staring up into the dark. The answer was far from obvious. Ordinary criminals were no longer enough, and even trained assassins were becoming insufficient. Caius needed opponents who could force him to adapt again—enemies whose abilities were distinct enough that the boy could not simply rely on what he had already mastered.

He needed someone ruthless. Someone unpredictable. Someone capable of actually killing him.

Old Bones stared into the void. The Patriarch had placed Caius under his supervision, a responsibility he had accepted willingly. He had expected to train a talented young warrior. Instead, he had ended up with a boy who devoured every lesson thrown at him without missing a beat.

His mouth twitched. "You're becoming troublesome, boy."

He closed his eyes again, but sleep remained far out of reach.

Far from the physical training hall, another battle was taking place.

Inside Caius's Crown Core, the vast courtyard surrounding the ancient temple had become a realm of constant conflict. The flame demon and the Arachne princess fought whenever they were released from their circles. Neither seemed particularly interested in victory or defeat; they simply possessed the primal instincts of beings born for combat, and the Crown Core offered an endless arena in which to collide.

Caius sat upon the temple steps, his chin resting against his hand as he watched them. He was no longer interested in who won. He was studying them.

The flame demon moved with savage unpredictability, its body shrouded in elemental fire as it manipulated floating weapons through invisible links. The Arachne princess answered with intricate thread arts, weaving constructs and manipulating them as naturally as a warrior moved her own limbs.

Caius's vision shifted. Fate Sight spread across the battlefield, peeling back layers of reality to reveal the energy hidden beneath physical movement.

The fight slowed in his perception.

Mana flowed through the flame demon. Threads of intent connected its Crown Core to the weapons it manifested. The Arachne princess moved in response, her own mana tracing paths that Caius had already analyzed countless times.

The narrative has been illicitly obtained; should you discover it on Amazon, report the violation.

Then something caught his attention. He narrowed his focus on the Arachne.

The threads surrounding her were different from the simple strands she used to bind or strike. They were deeper. More intricate. They seemed to originate from the very core of her being before extending outward to anchor into the constructs she created.

Caius remembered something else—during their final battle in the real world, the princess had commanded an entire horde of lesser Arachne warriors. She hadn't merely ordered them to attack; she had moved them with extraordinary precision, directing their bodies as though they were direct extensions of herself.

He narrowed his eyes. She was using her Crown Thread as a bridge.

Her intent had traveled through the threads and connected directly with another living body, allowing her consciousness to influence its movements.

He watched even more carefully. The principle became strikingly clear: the threads were not merely weapons. They were conduits. They carried intent, connecting the will of one being to something outside itself.

Caius leaned forward. "If her intent threads can bridge consciousness into another living vessel..."

His gaze shifted toward the black mana swirling around his own body. "What happens if I use my Black Core construct as that vessel?"

The thought lingered. He did not immediately attempt it. Instead, he observed the Arachne again, taking in the micro-movements of her fingers and how her Crown Core responded to each motion. He had already learned to reproduce the physical structure of her thread arts. He had already discovered that his Crown Core could supply intent while his Black Core provided the raw energy to give that intent physical form.

Perhaps the next step wasn't creating another construct. Perhaps it was learning how to connect himself to one.

The idea fascinated him.

A sudden shift in Caius's focus caused both combatants to pause mid-strike. The flame demon turned its gaze toward the temple. The Arachne princess followed suit. For several moments, the two entities simply stared at the human perched on the steps. Neither knew what he was thinking.

Then, Caius's consciousness withdrew from the Crown Core.

The courtyard plunged into silence. The flame demon eventually returned to its circle, and the Arachne princess did the same. Neither understood what had just occupied the human's mind, but both had learned enough about Caius to know that his silence usually meant something was about to change.

In the physical world, Caius opened his eyes. Cool air filled his lungs. He remained seated for a moment, contemplating what he had seen, before finally standing.

Old Bones was nearby, resting in his usual corner of the training abode. The old assassin opened one eye as Caius approached.

"I need an Arachne warrior," Caius said.

Old Bones slowly opened his other eye. "A live one."

The elder stared at him. "What?"

"For training."

Old Bones pushed himself upright, his expression twisting into sheer disbelief. "Why in the nine hells would you need a live monster brought into the estate?"

Caius looked down at him, his face completely devoid of humor. "I need to study its thread arts."

Old Bones stared at the boy for several long seconds before rubbing his temples. Of course. Naturally. Caius had defeated an Arachne princess, learned her techniques, discovered ways to reproduce them, and now apparently wanted to dissect the fundamental principles behind the entire race's fighting methods.

"Fine," Old Bones muttered. "I'll inform the Patriarch that you require a live specimen for combat practice. But don't blame me when it tries to bite your head off."

Caius turned toward the doorway. "One more thing, Old Bones."

The elder looked up.

"Ensure all its limbs are completely intact. I need it healthy, unmaimed, and very much alive."

Old Bones stared at him in silence before letting out a long, exhausted groan. "You are going to drive me to an early grave, boy."

Caius left without answering.

Old Bones watched him disappear through the doorway, remaining seated for several moments before shaking his head. The boy hadn't asked for an Arachne because he wanted another opponent to kill. He wanted to understand them.

That was somehow so much worse.

A week later, the heavy sound of iron wheels echoed through the subterranean corridors.

A reinforced cage was dragged toward Caius's private training abode by a squad of dark elf warriors. Inside, a massive creature threw itself violently against the bars, its mandibles clicking as dark silk sprayed from its mouth and struck the iron. The entire cage shook with every impact.

The warriors pulling it remained visibly tense, their hands tight on their weapons despite the restraints. Their armor was scorched and dented from the struggle, while torn fabric and fresh bandages revealed just how difficult the capture had been.

Inside the cage, the Arachne warrior continued to thrash, its cluster of eyes burning with pure hatred.

At last, the squad captain stopped before the training hall and leaned heavily against his spear, his face pale with exhaustion. "We got it, young master," he panted. "No casualties. Limbs fully intact, just as requested."

The captain glanced back at the snarling creature. "It is healthy."

Behind him, the Arachne slammed against the bars once more, making the iron frame groan under the strain.

Old Bones, standing beside Caius, slowly cracked a smile.

Caius stared at the creature, his eyes entirely calm. He had found his next lesson.
