The mist was getting thicker.
It wasn't just water vapor anymore; it was a physical barrier, a wall of grey cotton that swallowed sound and diffused the light until Sasuke couldn't tell where the sun was.
The dampness coated his eyelashes, blurring his vision with a film of condensation that he couldn't wipe away without letting go.
The only reality was the rock face inches from his nose and the slippery, terrifyingly narrow ledge beneath his boots.
Every breath tasted of wet stone and the faint, metallic tang of the mineral-rich water dripping from the overhangs.
"Hold," Kakashi's voice drifted down from above, muffled by the fog. "The angle steepens here. Eighty-five degrees. Watch your center of gravity."
Sasuke gritted his teeth, his fingers aching. He was clinging to the "Second War Fortification" like a spider, his body pressed flat against the stone. The moss here was treacherous—a thick, velvet carpet of green slime that oozed water every time he put weight on it.
It smelled earthy and ancient, like soil that had never seen the sun.
Squelch.
He shifted his left foot. The boot slipped a fraction of an inch before finding purchase in a niche carved by a Suna sapper fifty years ago.
This is humiliating, Sasuke thought, sweat stinging his eyes. I am an Uchiha. I breathe fire. And I am being defeated by vegetables and gravity.
"Movement," Neji whispered from below. "Left flank. Three signatures. Small. Fast."
"More monkeys?" Sasuke hissed. "I'm going to roast them."
"Don't," Tenten warned, her voice surprisingly close. "You fire a jutsu here, the recoil knocks you off. Unless you want to learn to fly, keep your chakra inside your body."
A pebble clattered down from above—tink-tink-tink—signaling movement before the shadows even appeared.
Screech.
A shadow detached itself from the mist.
It wasn't just one. It was a troop.
Six monkeys, their fur matted with the same green moss that coated the rocks, swung effortlessly from the overhangs. They moved with a fluid, terrifying grace that mocked the ninja's cautious descent.
Their chattering echoed weirdly in the fog, bouncing off the cliff face so it sounded like they were everywhere at once.
They were gatekeepers, and they knew the terrain better than anyone.
One of them landed on Sasuke's shoulder.
It felt heavy, warm, and smelled of wet musk and rotting fruit.
Its fur was coarse and oily, slick with the same green slime that coated the rocks.
"Get off!" Sasuke jerked his shoulder, trying to dislodge it without letting go of the wall.
The monkey screeched, digging its claws into his flak jacket. It wasn't attacking him; it was reaching for his hip pouch. The one with his rations.
"Hey!" Sasuke shouted, kicking out with one leg.
The monkey dodged easily, using Sasuke's own leg as a springboard to leap to Neji.
Sasuke felt the sharp dig of its claws through his pants leg—snag—before the weight vanished.
Neji, who was clinging to a particularly slick section of rock, froze.
"It is... interfering with my chakra points," Neji gasped, as the monkey sat on his head, covering his eyes.
Neji flailed blindly, his white robes snagging on the rough stone with a ripping sound—rriipp.
"I cannot see!"
"Shake it off!" Sasuke yelled.
"I can't let go!" Neji panicked, his fingers white-knuckled on the stone. "If I move my hands, I fall!"
The prodigies of Konoha—the Byakugan and the Sharingan—were paralyzed. Their mobility, their greatest asset, was gone. They were statues on a wall, helpless against a foe that didn't play by the rules of ninjutsu.
The wind howled through the narrow gap between their bodies and the wall, a cold draft that chilled the sweat on Sasuke's neck.
Click.
A metallic sound cut through the panic.
"Anchor set," Tenten announced.
The sound was crisp and industrial—SNAP-CLICK—a jarringly modern noise in the primal landscape.
Sasuke looked up.
Tenten wasn't clinging to the wall anymore. She had driven a piton—a metal spike—into a crack in the rock. A carabiner was clipped to it, and a rope was secured to her harness.
She leaned back, trusting the gear completely. She was hanging perpendicular to the cliff face, her feet braced against the stone, her hands free.
The rope groaned under tension—errr-errr—but held firm, vibrating slightly in the wind.
"Target practice," she grinned.
She reached into her scroll. She didn't pull out a kunai. She pulled out a slingshot.
"Serious?" Sasuke muttered.
"Quiet, Uchiha," she snapped.
Thwip. Thwack.
She fired a clay pellet. It hit the monkey on Neji's head right in the ear. The animal shrieked, letting go and tumbling into the mist.
The impact made a dull thwack, like hitting a ripe melon.
Thwip. Thwack. Thwack.
She fired rapidly, reloading with a speed that blurred. She wasn't killing them; she was stinging them. Every shot was a lesson in pain.
The monkeys scattered, chattering angrily as they retreated into the cracks of the cliff.
"Clear," Tenten said, unclipping her rope and sliding down to Neji's level in a controlled rappel. "You okay, Hyūga?"
Neji, looking pale and thoroughly embarrassed, nodded. "I... yes. Thank you."
"Why do you have a slingshot?" Sasuke asked, staring at the toy in her hand.
"Because kunai are expensive," Tenten shrugged, re-hooking her anchor to a lower point. "And because sometimes you need to be annoying, not lethal. Also, I can't throw a shuriken while hanging upside down. Physics."
She adjusted a strap on her harness, the buckle clicking softly, smelling of oiled leather and steel.
She looked at Sasuke, her brown eyes dancing with amusement.
"You guys rely too much on your bloodlines," she said, tapping her harness. "Sometimes, you just need a good piece of rope and some geometry."
Sasuke looked at the carabiner. He looked at the rope. He looked at his own trembling hands, still gripping the mossy rock.
His fingers were cramped into claws, the knuckles white and aching from the sustained tension.
He felt a flash of irritation, but beneath it, a grudging respect.
She engineered a solution, he realized. She didn't try to overpower the mountain. She adapted to it.
"Team Carabiner," Kakashi called from above, his voice laced with amusement. "Let's keep moving. The air is getting thicker. We're almost to the jungle floor."
Below them, the grey mist began to turn green, the smell of ozone fading into the thick, rotting scent of the swamp.
Sasuke lowered his boot, feeling for the next niche. He moved slower this time. More deliberately.
Adapt, he told himself. Or fall.
