The stream ran cold and murky between two moss-slicked embankments.
High above, nestled in the dense foliage of a weeping cedar, Ren crouched on the balls of his feet. His sensory radius mapped the clearing with microscopic precision: three distinct chakra pools submerged waist-deep in the muddy water, breathing through hollow reed tubes.
To the untrained eye, the stream looked undisturbed. But Ren could see the nearly invisible monofilament wires strung between the roots, linked to spring-loaded bamboo tubes hidden beneath the silt.
Rain Genin. Standard tri-point ambush. Water-style users waiting for someone to cross the shallows before triggering a pressurized needle volley from below.
Solid setup for a swamp environment.
Unfortunately for them, water was an exceptional conductor.
Ren reached into his hip pouch and produced four steel senbon. He channeled a faint, high-frequency Raiton current through his fingers—the metal hummed, generating almost no visible glow, just a faint distortion of the humid air.
He dropped from the branch.
No rush of air. No war cry. He stepped off the wood and plummeted twenty meters, arresting his descent three feet above the surface with a controlled pulse of chakra at his soles, hovering weightlessly over the stream.
The three reeds froze.
Ren flicked his wrist.
Thwack. Thwack. Thwack. Thwack.
The four vibrating needles struck the stream at precise geometric coordinates, sinking into the silt. He clamped his right hand into a single half-tiger seal.
"Discharge."
BZZZZT.
A pale blue web of low-voltage current cascaded through the sixty-foot stretch. The water didn't explode—it turned into a conductor.
All three submerged figures convulsed. Motor nerves locked, breathing tubes popped free, and they broke the surface coughing and paralyzed from the chest down.
Ren stepped onto the gravel bank. His boots were completely dry.
…
"Ah... dammit—" The lead Rain ninja—the one with the respirator from outside Room 301—collapsed face-first into the mud, limbs twitching. His fingers clawed at the dirt once, twice, then went slack. "You... you bastard..."
"Keep your face out of the silt." Ren walked over without urgency and hooked his foot under the boy's chest, flipping him onto his back. "You'll inhale mud while the paralysis wears off."
The leader's respirator was cracked at the seal, leaking thin wisps of mist. He stared up at the canopy with glazed, furious eyes.
The other two had dragged themselves against the mossy bank. One had a hand halfway to his weapon holster before the numbness stopped him. He sat frozen mid-reach, glaring through his rain goggles. The third had gone very still, watching Ren the way a cornered animal watches something it can't outrun.
"Don't bother," Ren said, glancing at the one still reaching. "The voltage was calculated for motor nerve disruption. Your fine muscle control won't return for another twenty-two minutes." He crouched beside the leader. "If you try to force it, you'll just cramp."
"Twenty-two minutes." The second Genin's voice was tight. "You calculated—" He stopped, jaw working behind his goggles. "What kind of person calculates that mid-drop?"
Ren didn't answer. He reached down and unclipped the cylindrical scroll canister from the Rain leader's belt.
Heaven Scroll. Wax seal intact.
"Perfect match," Ren murmured.
He tapped his collarbone. The scroll dissolved into thin air, slipping into the second slot of his Spatial Storage Inventory.
The leader stared at the empty space where the canister had been—at his own belt, his own hands lying useless in the mud. Something in his expression cracked open.
"Where—" His voice came out hoarser than he'd intended. "Where did it go? Who the hell are you?"
"Just a solo reserve," Ren said, standing.
He turned away and pulled three lengths of hemp rope from his pack, shaking them loose with a quiet snap.
"Hey—" The leader craned his neck. "What are you doing?"
Ren crouched beside him and looped the rope under his shoulders. "There are giant leeches in the lower brush. Venomous centipedes too, this close to the water line. Leaving you in the mud while paralyzed is basically an execution sentence."
A pause.
"...So you're tying us to a tree."
"Eight feet up." Ren cinched the knot and tested it. "High enough."
"High enough—" The second Genin made a sound that was almost a laugh. "You just—you electrocuted us—"
"Low voltage." Ren had already moved on to him. "You'll be fine."
"That is not the point—"
"I know."
He hoisted all three of them into the lower branches of a broad oak, methodically, without ceremony, and checked each knot with a firm tug. The three Rain Genin dangled side by side, staring down at him in a silence that had gone strangely soft.
Ren reached into his pocket. Three wrapped nutrient bars. A clean canteen. He tucked them into the leader's open vest pocket without comment.
The leader looked down at the canteen. Then back up at Ren.
"...Why?" he rasped.
The third Genin—the quiet one—finally spoke. "We set an ambush for you."
"I know." Ren picked up his pack and settled it across his shoulders. He glanced back toward the stream. "It was a good one, actually. Standing water traps work well in this environment. Just remember they work both ways if your opponent has lightning affinity."
He turned toward the tree line.
"Eat after the numbness fades. Don't try the knots before then—you'll just tire yourself out."
"Hey—" The leader's voice came out rough. Ren stopped, one hand resting against the bark of the nearest tree. "Your name. What's your name?"
A pause. A small smile at the corner of his mouth.
"Life is short," Ren said. "No reason to waste it over an exam scroll."
He bent his knees and vanished into the canopy, leaving the three Rain Genin suspended in the branches, the canteen sitting warm in the leader's vest pocket, the forest settling back into its quiet hum.
The quiet one stared up at the hole in the leaves where he'd disappeared.
"...What just happened."
The leader closed his eyes. Exhaled.
"I have no idea."
…
Ten minutes later, five kilometers deeper into the Forty-Fourth Training Ground.
Ren was moving through the high branches at a steady thirty miles per hour when a violent atmospheric tremor rippled across the forest.
BOOOOOOM.
The shockwave snapped massive branches two kilometers to the south. A hurricane-force gale tore through the canopy, stripping leaves, sending flocks of giant birds screeching into the overcast sky.
Through his Sensory Clarity, Ren felt it: a massive, suffocating vortex of corrosive wind. Naruto's crimson beast-chakra, frantic. Sasuke's sharp fire release, panicked. And dominating everything—the ancient, serpentine dread of Orochimaru.
Ren landed on a thick bough. The air smelled of ozone, burnt wood, and sulfur.
Team 7 just met the Sannin.
An impulsive ninja might have turned and charged. Ren didn't. Orochimaru was a legendary monster—even Hiruzen Sarutobi would die fighting him in three weeks. Jumping into that clearing as a fifteen-year-old reserve Genin wouldn't save anyone. It would get Ren dissected in an underground Sound laboratory.
Naruto had the seal of the Nine-Tails. Orochimaru wouldn't kill him. Sasuke was his intended vessel—he'd receive the Curse Mark, not death.
Ren exhaled slowly.
"Stick to the mission," he murmured. "Get stronger. Decode the wards."
He turned his eyes toward the center of the forest. Rising through the sea of colossal green trees was the massive concrete silhouette of the Central Tower, its monolithic stone walls covered in ancient seals.
He leaned forward and accelerated.
…
Twenty minutes later, Ren emerged into the wide stone plaza surrounding the Central Tower.
Dead quiet. He was the first candidate to arrive.
The moment his sandals touched the stone landing, his collarbone flared with a warm, rhythmic pulse.

He looked up at the towering kanji etched into the lintel above the bronze doors and stood there a moment, the forest still humming distantly behind him.
Both scrolls secured. No injuries. Team 7 alive, if not unscathed.
A small smile.
"Plenty of reading material too."
He pushed the doors open and stepped inside.
