"Damn—this needle is way too fucking thick!"
Naruto gritted his teeth, tears welling in his eyes.
Holding the metal syringe that gave off a chill, he spent ages aiming its tip at the inside of his thigh, his hand trembling the entire time.
"Uncle Yoru, can't we use a thinner one? I'm scared of pain."
Naruto sniffled and looked at Yoru pleadingly, like a puppy about to get beaten.
"Shut up."
Sasuke's face was cold as he snatched the syringe from Naruto's hand.
Without even looking, he jabbed it straight into a vein in his left arm with a wet squelch.
Bracing the plunger with his thumb, he pushed down hard.
The thick, dark-purple fluid was instantly injected into his veins.
"AAAAARGH—!"
The pain drove Sasuke straight to his knees. Clutching his arm, he rolled frantically across the ground.
His usually cool face was now completely twisted, his mouth filled with the taste of blood.
Cold sweat poured down like a waterfall, blasting tiny pits into the muddy ground.
That violent Yang Release chakra felt like someone had stuffed a ball of burning magma into his veins.
"Holy shit! Sasuke!"
Naruto jolted in fright, nearly dropping the syringe in his hand.
Watching Sasuke convulse in pain on the ground made his scalp crawl.
Yoru walked over and kicked Naruto in the ass, sending him sprawling face-first into the dirt.
"Didn't your Kurama claim to have limitless chakra? You can't even handle this much pain?"
Yoru took the syringe from Naruto's hand.
"Orochimaru traded the lives of a hundred thousand White Zetsu for this medicine. Even if you cry for your daddy and mommy today, you're swallowing it."
With that, Yoru mercilessly plunged the needle into Naruto's neck.
Golden-red liquid instantly flooded into his body.
"AAARGH! Old fox, save me!"
