Naruto: Analyzing the Nine-Tails from the Start, I'm Invincible

Transmigrating into the Naruto world, he starts with the hellish difficulty of the Nine-Tails' rampage. Fortunately, Ling Xuan awakens the ultimate cheat—the Eye of Truth! His left eye analyzes everything: ninjutsu, bloodline limits, energy, laws... All essence is laid bare before him, seen through at a glance, perfectly replicated, and even optimized beyond! His right eye absorbs and converts: any energy can be used by him, transformed into the purest chakra and life force, making him a perpetual motion machine! As an infant, he closely watches the Fourth Hokage battle the Nine-Tails and sacrifice his life to seal it—the intricacies of the Flying Thunder God Technique, the terror of the Dead Demon Consuming Seal, the mysteries of the Yin-Yang Seal... Entering the Ninja Academy, he quietly discerns the five chakra nature transformations. He is the "highly talented but exceptionally low-key" orphan in Iruka's eyes, and the "mysterious guy" that Sasuke secretly guards against. While his peers struggle to release a single C-rank ninjutsu, Ling Xuan has already seen through all its flaws and casually optimized over a dozen stronger versions. When bloodline limits are regarded as the supreme glory of family heritage, in his eyes they are just "data packs" waiting to be analyzed and recombined. When Sage Mode is hailed as the threshold to becoming a top-tier powerhouse, the violent natural energy is as docile as a pet cat in his "eyes." "My eyes can see through everything, optimize everything, absorb everything!"
