Naruto : I Can Evolve My Gene Infinitely

Rin immersed himself in the newly acquired knowledge, dissecting the technical guide with the meticulous precision of a surgeon. The section dedicated to the biological chip was extensive, outlining every step from concept to creation.

The process of building a biochip required a suite of complementary technologies—probe anchoring, base material synthesis, microfluidic structure formation, and chip encapsulation. While some of these could be achieved with basic chakra manipulation, the more delicate procedures—especially microfluidic patterning—demanded extreme precision.

Fortunately, Rin lived in a world where chakra could substitute for machines.

Though only sixteen, Rin had already mastered all five nature transformations, a rare feat. His chakra reserves were modest, but his control was surgical, honed through years of training as a medical-nin.

Following the specifications in the manual, Rin employed Earth Release.

"Doton: Silicified Molding!"

Weaving the hand seals slowly, Rin summoned a complex chakra structure—silicon-based polymer infused with rare-earth elements, forming the substrate for his chip.

Earth Release, when mastered to the point of elemental alteration, allowed the user to simulate nearly any soil-derived substance, shaping it directly into the required form. Rin's manipulation went beyond shape—it infused the construct with precise material characteristics, skipping preprocessing steps entirely.

The next task was forging molecular probes—integrating living tissue into the chip's interface. This was trivial for someone with Rin's mastery of the Blood Shadow gene. He extracted specific neural contact markers from blood cells and fused them with the base substrate.

Once the substrate and probes were complete, Rin activated his Sharingan.

Three tomoe spun in his eyes.

He wove a genjutsu, pulling his mind into a construct where time and scale bent to thought. There, he simulated the photolithography and nano-imprinting procedures needed to etch microfluidic circuits.

The process drained nearly all his ocular chakra.

But when he emerged, the biochip was complete.

His Sharingan faded back to a normal pupil, his eyes heavy with exhaustion, but beneath the weariness burned the spark of victory.

This was just the beginning.

With the biochip complete, Rin now had the foundation for countless new paths:

First—developing a bio-computer capable of analyzing and simulating the Izanagi technique.

Second—creating a neural memory storage system for ninjutsu, enabling chip-based jutsu download and implantation, bypassing traditional training.

Third—constructing full-scale bio-armor, using Susanoo as the structural blueprint for a powered exoskeleton.

He began with the first—building a bio-computer.

The manual described how to construct a primitive processor using brain tissue as a biological motherboard. Rin simulated the chip's integration into a neural network using his Evolution Calculation ability. By linking the chip to brain synapses, he verified it could indeed function as a processor.

However, the human brain's complexity drastically limited the chip's processing space. Rin estimated that at least three or four progressive generations of chips would be needed for fully independent neural integration.

So, he devised a workaround.

Rather than inserting the chip directly into the brain, he would embed it inside a Sharingan.

The ocular nerves would serve as conduits. The Sharingan, acting as a chakra-conducting medium, would fuel the chip's operations without overloading the host.

"Shisui, how's your recovery?" Rin called out as he stepped into the base's training chamber.

Shisui, in the middle of blood-imbued kunai drills, paused and turned.

"I'm fully recovered, my lord. And I've completely mastered the Blood Shadow technique as you instructed."

He stood straight and bowed with flawless form.

"I need your help for another experiment," Rin said directly. "There's some risk involved. Are you willing?"

"I am," Shisui replied without hesitation.

His loyalty to Rin was absolute. Even death wouldn't deter him.

His life had been returned to him—he would spend it serving.

"Then follow me to the operating room."

Unlike the lab, the operating chamber was simpler. Clean, but not sterile. Entry required only a single change of clothes.

Rin brought with him a modified Sharingan embedded with the biochip.

The transplant was swift. No complications.

With a bit of medical ninjutsu, Shisui's vision was fully restored in under an hour.

"How does it feel?" Rin asked, watching the eye carefully.

In the depths of the tomoe, a faint blue glow shimmered. The chip's presence.

"Nothing unusual... wait—ah!" Shisui clutched his temple. "It burns... it's hot…"

The biochip, now linked to Shisui's ocular and visual nerves, activated.

A surge of computational power fed into his brain.

Neural limitations shattered like glass.

Shisui's chakra spiked—his mental energy surged.

The three tomoe spiraled, converging under the chip's guidance into a crystalline red-blue rhomboid.

The biochip had unlocked what lay dormant.

A synthetic Mangekyō Sharingan—forced into bloom.

Each tomoe bent into a perfect ring, laced with a halo of piercing azure light.

A man-made miracle.

A new kind of dojutsu, born from chakra and machine.
