Naruto: I am Uchiha Shirou

The vast expanse of desert stretched endlessly, and amidst the ruins of the once-glorious Land of Roran, four figures emerged.

"Haha, Hokage-sama, as expected, this body of yours is truly perfect. The Second Tsuchikage Mu's Fission Technique—this isn't a shadow clone, but genuine division..."

Beneath the ruins of Roran lay a secret underground base. Two Orochimarus, both wearing greedy smiles, stared at Shirou.

As Shirou slowly raised his head, a flicker of the Mangekyō Sharingan flashed in his eyes, leaving the two Orochimarus utterly captivated. To them, this was nothing short of divine artistry.

"The Fission Technique... a pure physical division. In other words, both chakra and physical strength are evenly split. Now, I..."

With a hoarse voice, Shirou squinted slightly, sensing the sudden halving of chakra and power within his body. He muttered softly:

"My current strength should only be half of what it originally was."

Nonetheless, it was still slightly stronger than the Five Kage during the Shippuden era and comparable to the power of the Rinnegan-wielding Pain.

"Hokage-sama, if our hypothesis is correct, then the two worlds are inherently connected."

Hearing Orochimaru's words, a faint smirk appeared on Shirou's lips. He slowly clenched his hand, which now possessed only half of its original strength. Although he wasn't fully accustomed to the change yet, he would adapt quickly.

"If our hypothesis is correct, then as long as my counterpart in the other world is strong enough, my Mangekyō Sharingan should be able to construct a space-time tunnel."
