Uchiha Shingen's gaze rested upon the Sharingan and Chakra options.
For a moment, he hesitated.
Chakra was one of the most core abilities for any ninja.
Even when using the same ninjutsu, the side that consumed more Chakra would inevitably unleash greater power.
As for the improvement in stamina, it would be nothing short of a complete transformation.
The Sharingan, however, was the foundation of the Uchiha clan and one of the strongest Kekkei Genkai in the ninja world.
Currently, Uchiha Shingen's Sharingan was at the Two-Tomoe level; upgrading it by one rank would, in all likelihood, bring it to the Three-Tomoe level.
This was practically an express ticket to the Jonin rank.
After a brief moment of contemplation, Uchiha Shingen focused his attention on the Sharingan.
His current level four Chakra was already quite abundant for a Chunin.
Under these circumstances, it was naturally a priority to upgrade the Sharingan, which could provide a qualitative leap in combat power.
With that thought in mind.
Uchiha Shingen reached a decision and reached out to lightly tap the plus sign next to the Sharingan.
Immediately, his vision blurred, and his eyeballs felt warm and tingling, as if countless ants were crawling over them, making him want to reach out and touch them.
Uchiha Shingen forcibly suppressed this instinct.
Having experienced the upgrade of the Sharingan before, he knew this was the sensation brought about by the increase in ocular power, and it posed no harm to him.
Even among the many Kekkei Genkai in the ninja world, the Uchiha's Sharingan was an absolute anomaly.
Unlike the vast majority of Kekkei Genkai, the Sharingan changed in accordance with the user's emotional fluctuations; the stronger the mental stimulation, the greater the ocular power it would produce.
The catalyst for his predecessor awakening the Sharingan had been an ambush by Iwagakure during a mission after graduation.
Every member of the squad, save for the team leader Jonin Inuzuka Gaku and himself, had perished right before his eyes.
The intense mental stimulation had forced Uchiha Shingen, whose talent was otherwise unremarkable, to awaken the Sharingan.
It was also after that battle that Uchiha Shingen's squad was disbanded; he did not choose to form a new squad with other comrades, but instead joined the Konoha Military Police Force.
Soon.
The changes in Uchiha Shingen's eyes subsided.
He slowly opened his eyes.
Within his pitch-black irises, three crimson tomoe slowly rotated around the pupil, eventually settling into a triangular formation.
"So this is... the world through the eyes of a Three-Tomoe Sharingan?!"
An unprecedented sensation washed over him.
Uchiha Shingen lifted his gaze to look forward; the Sharingan's already exceptional perception, now elevated to the Three-Tomoe level, had undergone a near-qualitative change.
His line of sight swept past the falling leaves outside the window, catching the frantic crawling of insects upon them.
He saw the flies darting past his eyes, even clearly perceiving the vibration of their wings.
"Everything has slowed down!"
As the words left his lips.
Uchiha Shingen realized that it wasn't that those things had slowed down, but that his own dynamic vision had become significantly more powerful.
He looked down at his palm, the lines clearly visible.
"Dynamic vision is merely one of the Sharingan's abilities."
Uchiha Shingen recalled what the elders of the clan had once said:
"The two great ocular Kekkei Genkai of Konoha."
"Between the Byakugan and the Sharingan, the one more focused on perception is not the Sharingan, but the Byakugan."
"The Sharingan is an eye more inclined toward techniques!"
"As long as one has sufficient Chakra, fast enough hand seals, and mastery of the corresponding nature transformations, a Sharingan user can even see through the technique an opponent is about to use and release it at a faster speed."
"It is just that very few people can actually do this, and in most battles, there is no necessity for it."
"It is an ability where the showmanship far outweighs the practical utility."
"After all, crushing an opponent with techniques one has already mastered is far more efficient than copying the opponent's ninjutsu."
Feeling the changes in his eyes, Uchiha Shingen initially wanted to test his abilities, but upon second thought, he abandoned the idea.
For one, testing ninjutsu would inevitably cause a commotion and be easily discovered by others.
A ninja capable of awakening the Three-Tomoe Sharingan at thirteen was rare, even in the history of the Uchiha.
Once discovered by the Konoha Military Police Force, Uchiha Shingen's days of lying flat and slacking off would effectively be over; he would likely be promoted directly to the captain of South District 4.
With a high position came heavy responsibilities.
Uchiha Shingen was quite satisfied with his current life and had no intention of changing it.
The second reason was to keep a trump card in reserve for a comeback.
The ninja world was far from peaceful; the Second Shinobi World War had ended long ago, and the situation was gradually becoming turbulent. No one could say for certain when the Third Shinobi World War would arrive.
When that time came, even if Uchiha Shingen could remain in the Military Police Force, he would inevitably have to face combat.
Thinking of this, Uchiha Shingen took a deep breath, suppressed the restlessness in his heart, and lowered his eyes to look at his panel.
Seeing that he had two skill points remaining, he simply threw them into Taijutsu Mastery, raising it to level three.
His physique visibly bulked up; the previously lean frame beneath his clothes became well-proportioned and sturdy, with defined muscle lines, and he even grew a few centimeters taller.
After doing this, the information on the panel changed significantly:
[Uchiha Shingen]
[Rank - Chunin]
[Position - Konoha Military Police Force South District 4 Third Squad Captain]
[Abilities:
--Chakra Level 4
--Kekkei Genkai - Sharingan - Three-Tomoe Level 5
--Fire Release Mastery Level 3
--Taijutsu Mastery Level 3
--Genjutsu Mastery Level 2
--Ninja Tool Mastery Level 1]
[Ninjutsu: Fire Release - Great Fireball Technique, Fire Release - Phoenix Sage Flower Nail Crimson, Body Flicker Technique...]
[Evaluation - A: Dojutsu-specialized Jonin, capable of leading a tactical squad on missions.]
[Remaining Skill Points - 0]
The evaluation increased to A, which means Jonin level?!
Uchiha Shingen's eyes were filled with excitement.
According to the information he possessed, the Check-in Device panel's B evaluation represented Chunin, and A represented Jonin. As for even stronger existences, he guessed they would be S or even SS.
Within Konoha, it was estimated that only a handful of people, including the Hokage, could possibly reach that level.
That was a combat power that transcended conventional ninjas, enough to sway the outcome of a war.
Even if there was still some distance to go, Uchiha Shingen firmly believed that as long as he was given enough time, he would inevitably grow to that level in the future.
However, for the time being, being a Chunin on the surface while possessing the true strength of a Jonin was sufficient within Konoha.
The excitement brought by the improvement gradually faded, and after a simple wash, Uchiha Shingen went to bed.
The following few days.
Uchiha Shingen's life did not change much.
Just like usual.
He clocked in for work during the day, slacked off while discussing the new work with Jiraiya, and went home at night to have a good meal to reward himself.
Deep within the Root organization.
Danzo's face was livid as he looked coldly at the several Root ninjas kneeling before him.
"Seven days!"
"Seven whole days, and not only have you failed to decipher the encrypted conversation between Jiraiya and Uchiha Shingen, but you haven't even had a chance to make individual contact with Uchiha Shingen?!"
