Chapter 49: Sealing Techniques
That night was pitch-black. One by one, the lights across Konohagakure gradually went out, until only the study room inside Izumo's house remained illuminated by a dim, yellow oil lamp.
The room was arranged with meticulous neatness. In the center lay a black ninja tool cloth, carefully spread across the floor. On top of it, every item he needed had been prepared and lined up with precision: an engraving pen forged from a tungsten-steel alloy, its tip embedded with a chakra-conductive ninja metal; a small bottle of ink mixed from cinnabar and powdered chakra crystals; three specially prepared shuriken already coated with poison; and two sets of kunai wrapped neatly in explosive tags.
Izumo sat cross-legged on a cushion. His left wrist rested flat atop the ninja tool cloth, palm facing upward.
He drew in a deep breath, his thoughts flowing inward as he reviewed several crucial aspects of Sealing Techniques.
"To apply Sealing Techniques onto the wrist, the core principle is to fuse the fuin seal with the skin's texture, using one's own chakra as the key. It must maintain Fuinjutsu stability, but it must never damage the meridians."
He lightly brushed the skin of his left wrist with his fingertips. In his mind, he had already planned out the pattern for the curse seal: using a core sealing symbol as the foundation, surrounded by three simplified storage symbols, then connected through a basic energy circuit. This structure wouldn't just enhance the seal's stability—it would also ensure that chakra could activate it instantly when needed.
He picked up the ink bottle and dipped the engraving pen into it.
The moment the ink touched the chakra-conductive metal at the pen's tip, a faint golden shimmer appeared. The powdered chakra crystals were responding.
Izumo held his breath. His right hand gripped the pen steadily, and the tip descended gently onto the inner side of his left wrist.
"Draw the base symbol first."
He focused completely. Chakra flowed through the meridians in his arm and into the engraving pen. Instantly, the pen's tip glowed with a dim blue light.
Where the tip touched his skin, a faint sting spread. But Izumo's hand remained as steady as stone, without even the slightest tremor.
The engraving pen moved slowly, leaving behind pale red traces—the core symbol of Sealing Techniques in the "Kan" position, the symbol of storage and stability.
Basic Fuinjutsu: Expert (999/1000) → Master (1000/10000)
The panel shifted silently. Every precise stroke of the symbol increased his Fuinjutsu proficiency.
Next came the symbol of the "Ri" position, representing chakra activation; the symbol of the "Shin" position, responsible for item transmission; and the symbol of the "Da" position, which controlled the retrieval mechanism.
The four core symbols formed a small square, each side measuring no more than three centimeters. The lines flowed smoothly, as if they were naturally growing across his skin.
Throughout the process, Izumo continuously adjusted his chakra output, ensuring the ink fully penetrated the texture of his skin rather than merely sitting on the surface.
When the final stroke completed the closed loop of the seal, his left wrist suddenly felt warm and faintly radiant. The four symbols seemed to come alive, slowly rotating.
Izumo could clearly feel his chakra tightly connected to them, as if this seal had always been a part of his body.
"Next, the storage circuits."
He didn't stop. The engraving pen continued moving, drawing three spiral circuits outside the four-symbol seal. Each circuit connected to one core symbol.
This was a modified design he had created based on the Sealing Method recorded in Basic Fuinjutsu. The three circuits were designated for ninja weapons, talisman papers, and scrolls respectively, allowing them to be stored separately and retrieved more quickly.
As he worked on the most critical sections, beads of sweat formed on Izumo's forehead. The mental energy required to inscribe this curse seal exceeded his expectations.
The stinging sensation from the pen scraping his skin intensified. A faint trace of blood seeped out, only to be immediately halted by the chakra crystal powder within the ink. That was the unique quality of this special ink—it could not only contain sealing energy, but also repair skin damage.
Half an hour later, the curse seal was finally complete.
On the inner side of his left wrist, a palm-sized curse seal rested quietly. All the symbols that had been drawn began moving rapidly, gathering together into a single "Seal" character before sinking beneath the skin and vanishing. The character would only appear when chakra was channeled into it, giving it exceptional concealment.
"Let's test it."
Izumo picked up the first special shuriken. Its edges had been coated with a paralysis poison, and a small identification marking had been carved into its handle.
He placed the shuriken atop the curse seal. His right hand formed a hand sign.
"Sealing Method: Formation — Sealing!"
Chakra flowed along the movement of his hand seal and into the curse seal. The "Kan" symbol at the center glowed with golden light, and an intangible suction force radiated outward.
The shuriken transformed into a point of silver light, slowly dissolving into the curse seal and disappearing.
At the same time, the first spiral circuit outside the seal emitted a faint silver glow, indicating that the ninja weapon had been successfully stored.
"Success!" Izumo felt a surge of satisfaction. He quickly picked up the second shuriken and the two sets of kunai, then performed the Sealing Method: Formation in sequence.
Each item transformed into a point of light and merged into the seal. The glow of the first spiral circuit grew brighter and brighter, and faint silhouettes of the stored items could even be seen flowing within the circuit.
Next came the explosive tags. Izumo picked up a specially processed roll of explosive paper that wouldn't ignite while sealed.
He formed the hand sign again.
"Sealing Method: Formation — Sealing!"
The "Ri" symbol at the center lit up with red light. The explosive paper transformed into a point of red light and merged into the second spiral circuit, which immediately filled with a deep crimson glow.
Once everything had been sealed, Izumo's left wrist looked completely ordinary. Only when he circulated chakra would the curse seal reveal its glow—subtle, yet incredibly practical.
He could feel every item stored within the seal. Each one's position and condition was perfectly clear to him, as if they were connected directly to his own body.
"Time to test retrieval."
With a single thought, Izumo focused on the first spiral circuit. His right hand formed another seal.
"Sealing Method: Formation — Release!"
A silver flash appeared along the first circuit of the curse seal. Instantly, a point of silver light shot out from the seal, condensed midair into the poisoned shuriken, and landed steadily in Izumo's hand.
The entire process took less than a second—smooth and flawless, without the slightest delay.
He also tried retrieving the kunai. With a single thought, two kunai instantly appeared in his left and right hands. He tried again with the explosive paper—a sheet of explosive tag materialized at his fingertips out of nowhere. Finally, he retrieved a scroll. A blue point of light flashed, and the scroll dropped into his palm. When he opened it, it remained completely intact, without any damage.
"Perfect!"
In the past, when heading out on missions, the capacity of a ninja tool pouch had always been limited. But now, with this storage technique, all of his frequently used ninja weapons could be stored directly within his body. The retrieval speed was several times faster than drawing from a pouch, and the level of secrecy was extremely high—enemies would never be able to predict his attacks.
As the blue panel lit up before his eyes, Izumo smiled in satisfaction.
