Although he didn't know exactly what Ui planned to do, Hizashi moved with the efficiency of a veteran. Using the back of the Yatagarasu as a makeshift desk, he quickly sketched the enemy's positions as seen through his Byakugan—mapping the four squads in their square formation, along with their precise depths.
Ui took the paper. His mind, processing data with the speed of a high-performance computer, overlaid the map with the effective range of his technique. A sense of relief washed over him; the enemies weren't too scattered. He could take them all out in one sweep.
"I happen to have a Forbidden Jutsu that's perfect for this," Ui explained, reaching into his tool pouch. He rummaged through the chaotic collection of gear for a moment before pulling out a small, black-covered scroll—no thicker than a thumb and barely ten centimeters long.
To Hizashi's Byakugan, the scroll was clearly under a seal, its contents obscured by a dense layer of protective chakra.
Ui clamped the scroll between his palms and formed a unique hand seal that deviated from the standard twelve. His left hand was horizontal, his right vertical, fingers interlaced in a complex pattern common in Uzumaki-style sealing arts.
"Release!"
With a soft poof and a plume of white smoke, the tiny scroll expanded to its original size: forty centimeters in diameter and over a meter tall. Ui tucked the large cylinder under one arm, unrolling a portion of it as the Yatagarasu made a low pass over the enemy's hiding spot. At a specific coordinate, he let it fall.
"I'm releasing the summoning now," Ui said.
"What exactly is the plan?" Hizashi asked, skeptical.
"Don't worry. Just leave it to me," Ui replied, exuding absolute confidence. He leaped from the bird's back, and Hizashi followed suit, landing silently on the dunes.
Knowing the enemy might have sensory ninjas, the two instinctively switched to silent hand signals.
Hizashi signaled: Is that scroll a wide-range sealing jutsu? You're going to trap them all?
Ui signaled back: Exactly.
Hizashi frowned: But a seal of that scale should cause a massive disturbance. How will you keep it quiet?
Communicating this way was a test of both vision and mental agility, but for elite shinobi, it was second nature. Hizashi still had his doubts; a single ninja shouldn't have the chakra capacity to maintain a 200-meter seal.
Ui signaled: This uses 'Silent Phase' processing... high power, massive radius, but zero acoustic signature. Perfect for a quiet disposal. (The intricacies of Leaf code allowed for surprisingly technical explanations).
Ui pointed to a spot directly above one of the hidden squads. Stand here. I'll flush this squad out. When they emerge, kick all four of them toward the center where the scroll is.
Hizashi gestured, confused: Why move them?
Ui clarified: This last group is just barely outside the effective radius. We need to 'deliver' them into the zone.
Hizashi understood. Even for a genius like Ui, there were limits. He chose to trust the boy—partly because Ui was Kushina's student, and partly because the formula he'd glimpsed on the scroll was so complex it was "impressively incomprehensible."
Ui signaled for Hizashi to get ready. The enemies were fifteen meters down. To force them up, Ui used a modified version of his signature lightning technique: Chidori Sharp Spear: Phase Two. By trading lethality for reach, he extended the spear to twelve meters. It still didn't touch them, but it didn't need to. A high-threat lightning surge piercing the earth so close would trigger any sensory ninja's alarm. If they didn't want to be buried, they would have to breach the surface.
Exactly as predicted, the moment the lightning bit into the soil, the earth erupted. Four Rain ninjas leaped out, weapons drawn.
Hizashi was a blur of movement. He unleashed a series of Eight Trigrams Vacuum Palms, striking all four enemies before they could find their footing. The force sent them flying exactly toward the central scroll.
Ui's hands finished the final seal.
The Forbidden Jutsu he was using? A modified, remote-triggered Reverse Four Symbols Sealing.
It would drain a massive amount of his chakra, but its power was absolute. Once triggered, it would collapse the entire area into a void, sealing everything within into eternal darkness.
