The Hibernating Fierce Beast and the Fire Thief

In the months following the Battle of the Valley, a strange, eerie calm settled over the borderlands.

Large-scale conflicts had uncharacteristically ceased, replaced by countless smaller, more insidious infiltrations, reconnaissance and counter-reconnaissance, and assassinations and counter-assassinations. The war had shifted from open legion clashes into a shadow game that tested patience, intellect, and unique abilities.

The Uchiha Clan was licking its wounds. The injuries sustained by Madara and Izuna were slowly recovering under the allocation of clan resources, but the use of the Mangekyo Sharingan clearly did not come without a price. Madara became increasingly reclusive; when he did appear, his aura was deeper and more unfathomable, yet a trace of imperceptible exhaustion occasionally flickered between his brows. Izuna took on more external affairs. His Mangekyo ability seemed to lean toward defense and perception; those deep eyes became sharper, always able to detect and thwart the many conspiracies of the Senju in time, though the old wound on his right chest would still ache on rainy days, a reminder of that day's peril.

Discussions within the clan regarding the two pairs of "God's Eyes" never ceased; awe and anticipation were intertwined, yet hidden beneath was unease. The power of the Mangekyo was formidable but carried an ominous air—a sentiment many veteran ninjas felt but left unspoken.

The Senju Clan was likewise silently accumulating strength. The Wood Style power that Hashirama Senju had initially awakened shocked the entire clan, and he was viewed as the hope to lead the Senju into a new era. He spent a great deal of time training alone in the forest behind the clan grounds, attempting to master and expand this newfound power. The grove he had coaxed into existence had already become a sacred site for the Senju, its vibrant life force even capable of accelerating the recovery of the wounded.

Tobirama Senju, meanwhile, was completely immersed in the development of forbidden techniques. The Mangekyo of the Uchiha brothers had provided him with immense stimulation and pressure. Although his Ghost Shadow Body Flicker Technique was extremely fast, it still carried risks when dealing with Dojutsu power capable of predicting or even interfering with space. He needed a technique that was faster, more bizarre, and impossible to defend against. His concepts regarding space-time barriers were gradually becoming clear, and his laboratory was piled high with scrolls concerning rune theory, summoning formulas, and even theories on instantaneous energy transfer. At the same time, the "Mutually Multiplying Explosive Tags" technique, based on explosive tags, was being continuously refined in pursuit of ultimate, instantaneous destructive power. His eyes grew increasingly sharp and cold, like a precision calculating instrument.

Beneath this relative calm, undercurrents surged. Both sides were desperately digesting the fruits of battle, enhancing their strength, and waiting for the next earth-shattering collision.

During this period, Uchiha Sou walked the edges of the clan grounds like a ghost.

He trained more diligently in standard Nintaijutsu and genjutsu, his use of the Double Tomoe Sharingan becoming increasingly proficient, and his strength steadily rose to the level of a core Jonin within the clan. However, this did not attract much attention; in this era, strength was a necessity for survival, not a capital worth showing off.

He poured the vast majority of his energy into the exploration of that special ability.

Ever since he successfully "stole" a glimmer of life in the medical barracks that day, he had found his direction, but he had also felt a "warning" from the unseen. He became more cautious, no longer using this ability on others lightly, instead focusing his practice entirely on himself and no longer pursuing specific, quantifiable effects.

He sat cross-legged under the moonlight, his spirit sinking into his body, no longer trying to "make wounds heal 1% faster," but continuously and repeatedly "mimicking" and "resonating" with the fluctuation he had perceived that day—the one where the "world" leaned toward "life."

This process was profound and mysterious, like trying to catch flowing water with one's hands or listen to colors with one's ears. Countless times, he exhausted his mind only to gain nothing, feeling only a void and his own insignificance.

But he did not give up. The temptation of establishing a connection with the underlying rules of the world was too great, especially after realizing that the world itself might be "biased." He felt a strong impulse to grasp something to fight against this unfairness.

He began to notice some extremely subtle changes.

When he continuously performed this "resonance" practice, the natural energy in a small area around him seemed to become extremely faintly "docile" and "active." It was not like the command-like control of Hashirama's Wood Style, but rather more like a kind of... friendly "inclination."

For instance, when he practiced in the early morning, dew would favor the blades of grass around him, refracting a more crystalline light; when he was exhausted, the breeze in the forest would happen to bring a cooler breath; when he attempted to refine Chakra, the process would become unusually smooth, and the rate of impurity production seemed to have a negligible decrease.

These changes were so subtle they felt like hallucinations, not even as obvious as the effect of a basic energy-gathering array. But Uchiha Sou's Sharingan and spiritual perception told him this was real! It was the extremely faint "causality" deflection of the surrounding environment brought about by his continuous "resonance"!

He was like a primitive man trying to drill wood for fire in boundless darkness, failing countless times, his hands worn raw, yet finally seeing a tiny spark that could be extinguished at any moment.

Though weak, this spark meant that light might exist.

He attempted to integrate this "resonance" state into his daily life. Whether walking, resting, or even executing simple missions, he would divert a portion of his mind to maintain that state of attempting to synchronize with the fluctuation of "life."

The effect was agonizingly slow, but he could feel his body undergoing a subtle transformation. His cells were more vigorous, his Chakra more pure, and even his Sharingan, often sore from overuse, seemed to receive a faint nourishment, its recovery speed increasing just a little bit.

He even began to risk another attempt—since he could resonate with "life," could he resonate with other "fluctuations"?

He recalled the cold, hateful, and destructive Dojutsu fluctuation that erupted when Madara and Izuna awakened their eyes on the battlefield, and he attempted to mimic it.

The result was an almost immediate backlash!

The moment he formed the intention and attempted to "resonate" with that power of hatred, a strong sense of nausea, dizziness, and palpitations struck him! The surrounding natural energy seemed to turn into cold needles, stabbing at his spirit! His eyes felt a violent, stinging pain, as if they were about to go blind!

He immediately stopped the attempt, gasping for air, cold sweat soaking his clothes.

The "partiality" of the world manifested once more; it rejected this power born of extreme negative emotion—at least, it rejected his attempt to invoke it in this manner.

Uchiha Sou wiped the cold sweat from his forehead, his heart becoming even clearer.

He roughly understood. This world (or rather, the will behind it) encouraged "life" and "fusion," and rejected "death" and "extremes." His ability seemed more like a Fire Thief, capable of stealing a few insignificant embers from the world's "inclination," but if he attempted to touch the power the world loathed, he would be met with a backlash.

This path was destined to be difficult and narrow.

But he had no other choice.

That day, he received a mission to escort a squad to the border bordering the Hagoromo Clan for a rotation of duties. It was a relatively simple mission, and he had expected it to be uneventful.

However, just as they were about to reach their destination, they were ambushed.

It was not the Senju, but a group of unidentified ninjas who were ruthless and well-trained. Their goal seemed to be to provoke conflict between the Uchiha and the Hagoromo Clan.

The battle erupted instantly. There were several experts among the ambushers with formidable strength, and the Uchiha squad fell into a bitter struggle.

Uchiha Sou held a Kunai, his Sharingan observing the entire situation as he grappled with an enemy using bizarre Earth Style. The opponent's Earth Style could not only defend but also create quicksand traps, making them extremely difficult to deal with.

During a fierce exchange, in order to rescue a comrade trapped in quicksand, Tsang left his back wide open!

Another ambushing ninja lunged from the shadows like a venomous snake, a poisoned short blade in hand stabbing straight for his heart!

Danger!

Uchiha Sou's Sharingan saw the sneak attack, but his body could not fully dodge in time!

At this critical moment, almost instinctively, he instantly reversed the weak state of resonance with "life" that he had been maintaining!

It was no longer an attraction toward the inclination of "life," but an extremely strained attempt to impose a thought of "misfortune" upon the attacker!

He could not directly harm the opponent; he could only attempt to deflect the most minute "causality"!

Slip underfoot! A strong, twisted intention erupted along with a violent expenditure of spirit!

Pfft!

The short blade failed to pierce his heart because the attacker inexplicably tripped, his movement distorted, and the blade grazed past Tsang's ribs, drawing a trail of blood!

A sharp pain followed, but it was not a fatal wound!

Tsang took the opportunity to turn and kick the off-balance attacker away, while simultaneously throwing his Kunai with precision, finishing off the Earth Style ninja.

The battle ended quickly, and the ambushers were all annihilated, but every member of the Uchiha squad was wounded.

His teammates crowded around to dress Uchiha Sou's wounds, their hearts still racing. "Tsang, that was too close! It's a good thing that guy just tripped on his own!"

Uchiha Sou clutched the wound at his ribs, feeling the searing pain and the dizziness brought on by excessive mental exhaustion, and managed a strained smile. "Yeah... just lucky."

Only he knew that it wasn't entirely luck.

At the brink of life and death, he had attempted for the first time to use this ability as an offensive "curse." Although the effect was merely making his opponent slip and the cost was immense and highly unstable, it proved that this path was not entirely impassable.

Yet, at the moment of success, that familiar, subtle sense of rejection and warning from the world emerged once more, a fraction clearer than it had been back at the medical barracks.

It was as if an indifferent voice were whispering in his ear: Fire Thief, be cautious. Those who toy with fate shall eventually be consumed by it.

Uchiha Sou took a deep breath, suppressing the chill in his heart.

He looked toward the gloomy sky in the distance, and further still, toward the direction of the Senju Clan.

He knew that peace was only temporary. Uchiha Madara would never let this rest, and Hashirama Senju and Tobirama were growing rapidly as well.

When those eyes of hatred opened once again, they would inevitably bring an even more violent storm of destruction.

And he, an anomaly quietly stealing the embers of this world, had to possess enough strength before that moment arrived—at the very least, the ability to preserve himself in the storm, or even influence its trajectory by a hair's breadth.

His path was destined to be lonely and dangerous. But he had already set foot on the journey, and there was no turning back.
