Ren stood still in the middle of the cell. His hand rose slowly, palm facing forward. The air in front of him looked perfectly normal, but to Ren, the world was never truly empty. He could feel it—the subtle flow of magic coursing through his body, like a gentle electric current traveling beneath his skin. It wasn't wild, and it wasn't fierce. It was elastic.
He exhaled a long breath.
"Let's begin again."
The first thread appeared. Invisible to the naked eye, but Ren could feel it with absolute clarity: a thin line of energy shooting from his fingertips. He aimed it at a large rock in the distance, about ten meters away.
Anchor.
There was a subtle sensation as the thread attached—like something sticky yet light, almost weightless. Ren pulled. The thread tensed, stretched, and then...
Snap.
Ren's brow furrowed slightly.
"Still too weak." He wasn't angry. Not frustrated. Just taking note.
He raised his hand again. This time, two threads at once. One to a rock protruding from the wall, and another to the wall on his left. He didn't pull immediately. Instead, he closed his eyes.
Ignoring his sight, Ren focused on one thing: feeling. He tried to "see" through his threads, sensing position, tension, angles, and even the texture of the surface where the threads were anchored.
The rock felt hard, cold, and immovable.
The wall felt solid, with subtle vibrations traveling through its surface, like the faint resonance of the earth supporting it. Not alive, but not completely still.
Ren smiled faintly.
"Interesting."
He pulled both threads simultaneously—not hard, but measured. His body moved. Not straight forward, but pulled into the center between the two points, as if tugged by two invisible hands. His feet barely touched the ground as he glided rapidly forward.
But just as he was about to reach the midpoint...
Snap.
One of the threads detached. He lost his balance. He stumbled, rolling on the ground before finally coming to a stop with one knee touching the floor.
Silence fell again. Ren did not get up immediately. He remained in that position, looking down, analyzing.
"Was the angle wrong... or was the tension unbalanced?" He raised his hand, looking at his fingers.
"No. Not that."
He recalled the sensation from moments ago. The moment one of the threads snapped off.
"The surface of the protruding rock moved slightly... so its adherence changed." His eyes narrowed slightly.
"That means... I have to adjust the elasticity in real-time."
He stood back up. This time, he didn't rush.
One thread. He anchored it to the rock. Then another, to the wall. But unlike before, he didn't pull immediately. He focused on the thread anchored to the rock. He "felt" the tiny vibrations of that rock, trying to adjust the flow of his magic to keep it stable even though the anchor point moved.
A little more energy.
A little more flexible.
A little more... pliable.
Ren pulled. His body melded into motion again—fast, smooth, and perfectly controlled. This time, nothing snapped. He landed lightly, right between the two points.
The corners of his lips quirked up.
"Better."
But he didn't stop. Ren turned around, his eyes sweeping the surrounding area. Rocks. Dirt. Twigs. Every object was a possibility. He raised both hands. Four threads. Each one shot off in a different direction—two to opposite walls, one to a rock, and another to the ground behind him. He pulled.
One pull → change direction → another pull → change again.
His movements began to grow irregular. Non-linear. Unpredictable.
But... Snap. Snap. Two threads snapped almost simultaneously. Ren lost his momentum, falling hard to the ground. Dust kicked up around him. A few seconds passed before he moved again.
He laughed softly. Not because it was funny, but because he was starting to understand.
"The limit... isn't the number of threads." He sat down, crossing his legs on the floor.
"...it's the control."
Ren closed his eyes again. He didn't create any threads right away this time. He just felt the flow of magic within his body. How the energy flowed out, shaped itself, tensed, and then dissipated. He began to realize something. All this time, he had been treating each thread as a separate entity. When in fact...
"They should be... a single system."
His eyes opened. He stood up slowly.
One thread shot out. Then two. Then three. But this time, there was no difference among them. No division of focus. Everything felt like an extension of the same consciousness.
Ren pulled. His body moved. But now, every change of direction felt natural. There was no lag. No conflict between one pull and another. Everything flowed. He glided between the left and right walls, bouncing from one point to another, spinning in the air before landing lightly on top of a rock.
No threads snapped. No movement was wasted. He stood still on top of that rock, his breathing a bit heavier, but his eyes were calm.
"This... is just the beginning."
But the training wasn't over yet. Ren jumped down and stared at the wall in front of him.
"Now... without moving."
He raised one hand. A thread shot out, anchoring to the wall a few meters ahead. He didn't pull it. Instead, he... tensed it. The thread stretched, nearly invisible, but full of pressure. Ren pushed a little more magic into it.
Tighter. more Tighter...
TWANG.
He released it. The wall suffered a small crack, as if struck by an invisible blow. Ren observed the mark. Not deep, but distinct.
"So... it can be used as a ranged attack." He nodded slightly, but then he shook his head.
"Too direct."
He raised his hand again. This time, he created two threads, anchoring them to two different points on the wall. He tensed them both... but did not release them. He left them there. Silent. Invisible. Waiting.
Ren stepped back a few paces. His eyes swept over the area. From the outside, nothing had changed. The wall still looked normal. No signs of danger. But Ren knew.
"If someone steps here..." He slightly twitched his finger.
Both threads would instantly pull, trapping, tripping, or completely shattering the target's balance.
A faint smile appeared on his face.
"The battle... has already begun before the enemy is even aware."
The wind blew again, bringing the scent of earth and leaves. Ren stood in the middle of the 'field' he had created himself—a network of invisible, elastic threads scattered all around him. He didn't move. He just felt. Every thread. Every tension. Every possibility.
In this place without enemies, Ren wasn't training to win. He was learning how to make it so the opponent... never had a chance to win. And behind that silence, something began to take shape. Not just a technique. Not just power. Rather, a fighting style that didn't require massive strength... didn't require incredible speed... didn't even require direct confrontation.
Only one thing: Control.
Ren opened his eyes slowly. And for the first time since the training began, he didn't try again. Because he already understood. The first step wasn't about attacking. It wasn't about defending. Rather, it was about mastering "space" itself. And within the space he controlled, he was the center.
