To elevate his Magnet Release, mastering Lightning-natured chakra was essential. Since Shiraishi had successfully unlocked his Lightning affinity, he had been scouring his collection of previously unlocked Electric-type skill cards to find a suitable technique for cultivation.
Eerie Impulse was Shiraishi's primary choice. According to the description within his specialized glasses system, Eerie Impulse is a peculiar form of electromagnetic wave.
By bathing the opponent in these waves, it causes a drastic reduction in their offensive potential—or in ninja terms, it acts as a unique debuff.
Shiraishi scanned the video interface within his vision, quickly absorbing the mechanics of the technique. From his perspective, it was effectively a "reverse-buff" Nintaijutsu.
While Hidden Cloud ninjas used Lightning Release to augment their speed and attack power, Eerie Impulse did the opposite: any ninja caught in the pulse would find their neural signals and physical coordination severely disrupted, weakening their defense and speed.
Noticing Shiraishi's distant gaze during dinner, Maki smiled. "Thinking about new jutsu development again?"
"Yeah. I plan to test something out in a bit."
Having spent so much time together, Maki could read his habits easily. However, she still hoped he would balance work with rest and not be too hard on himself.
"Don't overexert yourself." After dinner, Maki brewed a cup of tea and handed it to him, gently massaging his temples. They sat in comfortable silence, Shiraishi savoring this rare moment of tranquility.
Suddenly, a startled cat yowl broke the peace. The tubby orange cat was staring in horror at the Desert Blood Wolf in the backyard, looking like it had seen a ghost.
The Blood Wolf, however, ignored the fat feline entirely and focused on the meat Shiraishi had provided. It knew the cat was its master's pet and likely didn't taste very good anyway, but the cat's constant "posturing" and eventual "playing dead" whenever the wolf huffed was becoming a daily comedy.
"They seem to be getting along quite well," Maki remarked.
"Mm. Having the Blood Wolf keep an eye on him saves me a lot of trouble."
To test his new skills, Shiraishi bid Maki farewell and headed alone to the Hidden Sand's Special Training Ground.
In this massive facility, the silver sand on the ground churned and coalesced into a specialized needle. Around the tip of this needle, a cluster of purple, erratic electricity gathered—the Eerie Impulse.
The electromagnetic waves coiled in the air like mysterious, flickering purple auroras; the scene was as beautiful as it was dangerous.
Opposite him, a sand clone was hit by the pulse. It was instantly bathed in the purple glow. Shiraishi could keenly sense that the clone's structural integrity and "reaction speed" were significantly dampened.
As a support tool, Eerie Impulse was excellent, though its duration was short—usually lasting only about a dozen seconds. However, in a high-level shinobi duel, twelve seconds was more than enough to decide life and death.
Beyond Eerie Impulse, Shiraishi combed through his library of over twenty unlocked skills. He currently had six or seven he could use reliably, but his eye caught a specific Green-quality card: Fire Spin.
The prerequisite for Fire Spin was 100% proficiency in Fire Spark. Through his recent training and several rounds of card collecting, Shiraishi had completed the entire "Spark" progression line.
According to the skill tree, the path flowed from Spark to Fire Spin, eventually culminating in Inferno or Flamethrower. Since these Fire-type jutsus utilized Spark as a foundation, they shared a high degree of synergy with Pakura's Scorch Release, making them a primary focus for Shiraishi's elemental diversification.
According to the tutorial video, the execution of Fire Spin was actually simpler than Spark. Shiraishi could even bypass hand signs, relying on internal chakra flow to manifest the vortex of flames.
After organizing his Fire and Magnet Release techniques, Shiraishi finally looked at the centerpiece of his recent harvest: his only Gold-quality card.
The icon indicated a Wind-type (Flying-type) skill. Based on experience, Gold and Purple cards usually belonged to "Independent Zone" skills with unique properties. The "unlocking" bar had been filling since he returned to the village, and tonight, it finally hit 100%.
The true name of the Gold-quality Wind technique was revealed: Aerial Ace!
It was a sophisticated Wind Release attack that far surpassed his improved Whirlwind Blade(Gale blade). In the demonstration, the user manipulated atmospheric vortices to strike.
Its intense cutting force and frightening speed made it almost impossible to dodge, often striking vital points with unerring accuracy.
Wherever the air current traveled, it created secondary "sonic pops" or explosions, resulting in devastating destructive power. It was one of the strongest techniques in the Wind library.
The requirement for this move was Wind Release proficiency at a high-Jonin level. Shiraishi gripped his Sage's Blade, visualized the "vital strike" mechanic from the video, and swung his sword downward!
Wind coalesced in mid-air. The cutting speed was so high that even the backdraft left small nicks on Shiraishi's hands. Suddenly, the converging wind blades gathered on the sword, erupting into dozens of miniature tornadoes.
A deafening shockwave rippled through the air, as if a hundred Whirlwind Blades had merged into a single composite jutsu. The resulting explosive air pressure completely leveled the testing range!
I have to control the trajectory better...
The violent energy alarmed the Anbu patrols. Several ninjas appeared near the area, and upon seeing Shiraishi standing in the middle of the rubble, they immediately understood.
"Lord Shiraishi is testing a new jutsu again..."
"Sorry, I was a bit careless," Shiraishi said awkwardly. He hadn't expected Aerial Ace to be this powerful; even an incomplete execution had caused such catastrophic damage.
However, the backlash was evident—Shiraishi's palms were covered in fine, hairline cuts, highlighting the technique's raw instability.
"Lord Shiraishi... Mount Yanra in the back of the village might be more suitable for testing such high-powered techniques," whispered Arashi Arakawa. Since leaving his clan to join the Anbu under Ebizo's tutelage, this talented branch-member had risen to become a patrol captain.
"I've caused you trouble. I'll be more careful."
"No, please just take care of yourself, my Lord."
Arashi noticed the injuries on Shiraishi's hands and realized he was testing something extremely volatile.
He and his team quickly departed; according to shinobi tradition, they had to avoid watching the development of a secret technique.
Sheathing his blade, Shiraishi felt his heart racing. This unexpected explosive power was worthy of a Gold-quality card. If he could master Aerial Ace, the lethality of his silver blade would increase by several orders of magnitude.
