Everyone in Naruto Is a God, Yet My Immortal Cultivation Has Only Just Begun

[Naruto Fanfiction + Immortal Cultivation System + Frail but Scheming Protagonist + Everyone Misinterprets Everything + Pure Wish-Fulfillment]

Ye Tian transmigrates into the world of Naruto and awakens an immortal cultivation system. Yet, because the early stages of cultivating the Longevity Art require his body to purge toxins, he becomes Konoha's universally acknowledged “porcelain doll.”

He wheezes after taking two steps, collapses when the wind blows, and if he does not cough up blood at least twice a day, everyone assumes he is dead.

Until the Land of Waves mission, when Team Seven encounters Zabuza Momochi, the Demon of the Hidden Mist.

Thick fog blankets the sky. Kakashi is trapped in a Water Prison, while Sasuke and Naruto despair.

Ye Tian, who looks like he is about to stop breathing, tremblingly pulls out a talisman and presses it to his lips. Taking a deep breath, he says:

"Family Forbidden Technique-Lung Capacity Technique!!"

BOOM-!

With a single breath, he blows away the dense fog for hundreds of miles and sends the Seven Ninja Swordsmen flying!

Afterward, Ye Tian coughs up blood and collapses. "I can't... This move is way too hard on the lungs... Help me up. I can still finish my porridge..."

Sasuke: "I thought he was deadweight, but he was actually the hidden powerhouse! That blood... was he suppressing the terrifying power inside his body?"

Naruto: "Big Brother Ye Tian's 'isatis root tea' is so good! After drinking it, even the Nine-Tails stops making a fuss!"

Kakashi: "Ye Tian, stop pretending. Your 'medical ninjutsu' can even bring the dead back to life-get up and get to work!"

Tsunade: "His physical structure is practically a medical miracle! His pulse is completely absent, so why can one punch shatter Susanoo?!"

Ye Tian helplessly spreads his hands. "I'm really not showing off. I'm just cultivating immortality. Cough, cough... Lend me Samehada for a moment. I need to refine a flying sword..."
