A master swordsman knows that the blade is not an extension of the arm, but an extension of the mind. If the mind is clouded, the sword is dull.
For Kaiser, his mind was currently trapped inside the frail, easily exhausted body of a four-year-old child.
A year had passed since his mother smuggled the wooden training sword into the North Tower. In that year, Kaiser's physical routine had been agonizingly slow. A toddler's muscles lacked the density, the fast-twitch fibers, and the stamina to perform the devastating techniques he remembered from his past life. If he pushed too hard, his joints ached for days. If he swung with too much torque, he risked tearing his own undeveloped ligaments.
So, he practiced the absolute basics.
Step. Pivot. Strike. Breathe. In the center of the dark, circular room, the small boy moved with a terrifying, unnatural precision. The heavy black silk of his blindfold remained securely fastened around his eyes, the restrictive enchantments woven into the fabric constantly pressing against his temples.
Swish.
He swung the wooden sword, stopping it exactly one millimeter from the stone wall. He didn't need to see the wall to know it was there; he could hear the air compressing against the cold masonry just before impact.
He lowered the wooden blade, his small chest heaving. Sweat beaded on his forehead, rolling down his pale cheeks and soaking into the collar of his fine linen tunic. His physical limit had been reached for the day.
Kaiser sat down heavily on the plush rug, crossing his legs and resting the wooden sword across his knees.
Physical training was only a fraction of his daily battle. The true war was happening inside his mind.
In his previous world, his Absolute Senses were built on a clean, empty canvas. Air was just air. Sound was just sound. But in this world, the canvas was covered in thick, chaotic static.
Mana.
To Kaiser, mana was an ever-present, suffocating noise. It didn't obey the laws of physics. It didn't just vibrate when moved; it possessed its own frequency, its own weight, and its own intent. It pooled in the corners of his room like stagnant water. It drifted through the heavy oak door like a toxic gas.
For the past year, he had been trying to decipher it. If he couldn't filter the "noise" of mana, he would never be able to extend his sensory domain beyond the walls of his room. He would be truly, hopelessly blind.
Isolate, Kaiser commanded himself, slowing his breathing until his heartbeat became a steady, rhythmic thud in his ears. Stop fighting the static. Listen to the layers.
He focused on the space directly in front of him.
First layer: The physical. He heard the faint rustle of the rug's fibers settling beneath his weight. He felt the ambient temperature of the room—a cool fifty-eight degrees. He heard the distant, muffled sound of a stable boy brushing a horse in the courtyards, hundreds of feet below.
Second layer: The enchantments. He turned his focus to the black silk over his eyes. It emitted a high-pitched, tightly wound hum. It felt like a coiled spring, vibrating with complex, interwoven runes designed to suppress the catastrophic purple light of his Void Eyes.
Third layer: The ambient mana.
This was the hardest part. Kaiser pushed his awareness into the "empty" air of the room. Instantly, a roaring static rushed into his mind. It was overwhelming, a chaotic cacophony of energies clashing and merging.
Don't flinch, he told himself. His toddler body trembled, but his iron will held firm. Find a single thread.
He focused all of his immense willpower on a single, microscopic point in the air, right above the tip of his wooden sword. He tuned out the heavy thrum of the castle walls. He tuned out the enchantments on his face.
Slowly, the static began to separate.
It was like tuning a radio dial through layers of interference until a clear station broke through. He focused on a single particle of ambient mana.
There.
It wasn't just a sound; it was a texture. This specific cluster of mana had a distinct vibration. It felt... rigid. It hummed with a low, deep resonance, like a boulder grinding against bedrock.
Kaiser's lips parted in a small, breathless gasp.
He moved his focus to another cluster of mana drifting near the window. This one was entirely different. It vibrated rapidly, feeling thin, sharp, and erratic, like a sudden gust of wind whistling through a narrow gorge.
It has an element, Kaiser realized, a thrill of profound discovery sending a shiver down his spine. The energy in this world isn't uniform. It holds the properties of nature.
The rigid, grinding hum was Earth mana.
The sharp, whistling hum was Wind mana.
Because he could not see the visual colors of magic that the mages of this world took for granted, his brain was translating the magical spectrum into pure, auditory textures. He was learning to "hear" colors.
Suddenly, a heavy set of footsteps echoed in the hallway outside his room.
It was the changing of the guard. Kaiser immediately pulled his awareness back, analyzing the incoming vibrations.
The familiar, anxious hum of the day guards retreated. The new night guards approached. But as they stopped outside his door, Kaiser frowned behind his blindfold.
One of the guards was new.
His physical footsteps were heavy, clad in standard-issue steel boots. But his mana signature was unlike anything Kaiser had mapped in the castle before.
The new guard's internal energy wasn't just an ambient pool; it was violently active. It hummed with an aggressive, crackling frequency. It felt hot. The vibration was so intense that Kaiser could "hear" the air drying out around the man's body.
Fire, Kaiser deduced. A highly concentrated fire affinity. But it was more than just the element. The vibration had a unique rhythm to it, a strange, pulsating beat that didn't match the guard's physical heart.
Kaiser remembered the whispers of the maids who gossiped outside his door when they thought he was asleep. They had spoken of the nobility and high-ranking knights possessing "Special Physics"—genetic mutations in the body's mana pathways that granted extraordinary abilities.
This man has a Special Physic, Kaiser thought, his mind racing as he meticulously recorded the crackling, hot vibration into his memory. His mana pathways are physically altered to constantly generate heat. He is a living furnace.
This realization was the key he had been searching for.
If every person, every spell, and every element had a distinct "vibrational texture," then he didn't need to be overwhelmed by the noise anymore. He just needed to build a mental library. He needed to categorize every hum, every crackle, and every thrum until the static became a symphony he could read perfectly.
Kaiser slowly stood up, using his wooden sword as a makeshift cane to support his tired legs.
He walked toward the thick oak door, stopping a few inches from the wood. On the other side, the fire-attribute guard stood at attention, completely unaware that the four-year-old "blind" prisoner was studying the very structure of his soul.
Kaiser smiled. It was a small, chilling expression on the face of a child.
The world thought they had locked away a monster in the dark. They thought the blindfold made him powerless. But they didn't understand.
By blinding his physical eyes, they had forced him to open a different kind of vision.
Three years, Kaiser estimated. Give me three more years to map the frequencies of this castle. Then, the absolute domain will be mine once again.
