The so-called Heart Reflection Jutsu is a technique that transmits one's inner emotions and thoughts through spiritual intent, using the eyes to convey them to the target.
Through this, it disrupts the target's senses, thereby affecting their judgment.
On the surface, this seems like a normal visual-based Genjutsu, but upon deeper understanding, it becomes clear that this is not the case at all.
The most obvious indication of this is that its learning difficulty and the effectiveness of the Genjutsu are completely disproportionate.
According to what is written on the scroll, the learning difficulty of the Heart Reflection Jutsu reaches an A-level, but its actual effect is inferior even to some C-level Genjutsu of the same type.
If the previous self's parents wanted to learn Genjutsu, they definitely wouldn't have chosen this one.
But they did.
And they even treasured and carefully stored it away.
The reason for this is simple: this technique can help members of the Uchiha Clan awaken the Sharingan.
Uh.
At least that's what is recorded on the scroll.
The shinobi world has never lacked people with foresight, and the Uchiha Clan is no exception.
Long ago, some members of the Uchiha Clan became aware of the drawbacks of the Sharingan—not only is it difficult to awaken, but it also has a tendency toward extremes.
So, they wondered if there could be a gentler method to awaken the Sharingan, making the process more controllable.
In this way, they could not only enhance the strength of the Uchiha Clan but also bring more stability to the clan.
As a result, the Hyuga Clan's Byakugan came into their view.
As one of the Three Great Dojutsu, the awakening process of the Byakugan is much gentler compared to that of the Sharingan.
Even those without a pure bloodline can gradually awaken it through arduous training, reaching it after adulthood.
And this is something the Sharingan does not possess.
The Sharingan of the Uchiha Clan requires intense mental stimulation to awaken.
Once a person reaches adulthood, their worldview is essentially set.
They've gone through most of their life experiences, and unless they encounter some major emotional shock, it's nearly impossible to awaken the Sharingan after reaching adulthood.
So, they considered whether they could develop a training method inspired by the Hyuga Clan's approach to the Byakugan.
It was in this context that the Heart Reflection Jutsu was created.
Its principle is to mimic the changes in chakra and mental energy that occur in the brain when the Sharingan activates its hypnosis ability, stimulating the brain, visual nerves, body cells, and mental energy in reverse, thereby triggering the awakening of the Sharingan.
It's akin to creating a nurturing environment suited for the Sharingan to manifest, allowing the bloodline's power to take effect and flourish in this environment.
They succeeded, but they also failed.
They succeeded because the Heart Reflection Jutsu can indeed assist in awakening the Sharingan, but they failed because its effectiveness is far too limited.
According to the records on the scroll, many members of the Uchiha Clan once practiced this technique, but not a single one of them managed to awaken the Sharingan through it.
If the developer hadn't sworn that this technique was effective, and if those in the clan who had already awakened the Sharingan hadn't confirmed that it could indeed facilitate the evolution of the Sharingan to some extent, everyone would probably have considered it just a well-meaning lie.
However, its high difficulty level and barely noticeable effects still made it a dispensable technique.
After all, Uchiha members who had already awakened the Sharingan had no need to learn it, and those who hadn't would find it pointless to go through so much effort for little result.
With this, how could it not be neglected?
Now, within the Uchiha clan, only a few who refuse to settle for mediocrity still attempt to practice this technique, while the others have never even heard of it.
No wonder Seimei didn't know about it.
Speaking of which, Seimei's parents had kept this technique, evidently unwilling to be ordinary themselves.
Unfortunately, before they could master it, they lost their lives on the battlefield.
However, Seimei will carry on their will, using this technique to awaken the Sharingan and becoming the first in Uchiha history to do so with the help of this technique.
Others might be limited by their aptitude or lose patience before they can master the Heart Reflection Jutsu to the level of the Elders.
But Seimei will not.
With the existence of the Progress panel, he can see and grasp every bit of progress, no matter how small.
Therefore, as long as he confirms its genuine effectiveness, Seimei will not give up.
This will be his key to reaching new heights.
"Phew—"
After taking a deep breath to calm himself, Seimei picked up the scrolls containing the Fire Release: Great Fireball Jutsu and the Heart Reflection Jutsu and left the study.
In the next half month, he plans to dedicate half of his energy to practicing these two Ninjutsu and Genjutsu, not aiming for mastery, but just to become familiar with them.
Judging by the relatively lively state of the village, it seems that the front-line situation hasn't completely deteriorated, so it's unlikely that they will send new recruits like him directly to the battlefield.
This way, he would have a buffer period.
By then, he plans to master the Fire Release: Great Fireball Jutsu as a trump card, and in the meantime, observe the effects of the Heart Reflection Jutsu.
If possible, it would be best to awaken the Sharingan, which would give him an additional means of self-preservation on the battlefield.
With these thoughts in mind, Seimei began his training for the night.
...
In the blink of an eye, half a month passed.
It was now the end of September.
At this point, there was only one week left until the graduation assessment.
After understanding the assessment content, Seimei directly requested a week off to devote all his energy to training.
Normally, such a request would be difficult to approve, but at this stage, as long as the reason was reasonable, Sugiki Kazuto wouldn't offer much resistance.
Returning home, Seimei opened the panel.
[Name: Uchiha Seimei
Age: 10 years
Physique: 5
Spirit: 7]
[Chakra: 16 (192→372)
Bloodline: Sharingan · Not Awakened (51/100)
Skills:
Chakra Refining Technique: lv1 (1/200) → lv1 (91/200)
Clone Jutsu: lv1 (20/200) → lv1 (95/200)
Transformation Jutsu: lv1 (19/200) → lv1 (94/200)
Substitution Jutsu: lv1 (18/200) → lv1 (93/200)
Fire Release · Great Fireball Jutsu: lv0 (30/100)
Heart Reflection Jutsu: lv0 (30/100)
Basic Taijutsu: lv1 (65/200) → lv1 (185/200)
Ninja Tool Throwing: lv2 (42/500) → lv2 (120/500)]
Over the past half month, he has diligently trained in the Chakra Refining Technique for six hours every night.
Thanks to the powerful effects of lv1, his chakra limit increased by 12 points each day, resulting in a total increase of 180 points over half a month.
Therefore, compared to half a month ago, his chakra limit has nearly doubled, increasing from 192 to 372.
It takes about twenty chakra points to perform one of the Three Basic Jutsu, so with 372 chakra points, he can execute the Three Basic Jutsu about 18 or 19 times.
This level is roughly on par with most Genin.
In other words, apart from lacking some combat experience, his strength is already not inferior to that of seasoned Genin.
However, as his chakra increased, Seimei also vaguely sensed a limit.
This limit isn't from the Chakra Refining Technique itself but rather from the limits of his physical body.
The Chakra Refining Technique merely accelerated the efficiency of tapping into his potential; it doesn't directly increase the body's limits.
If his body were compared to a barrel, then the Chakra Refining Technique would be like a ladle for drawing water.
The amount of water the barrel can hold doesn't depend on the size of the ladle, but on the size of the barrel itself.
Physique: 5! Mental: 7!
Clearly, his "barrel" isn't large enough.
In other words, his body has its limits. Once his chakra reaches a certain level, it will stop increasing.
At that point, unless he can raise his body's upper limits, maxing out the Chakra Refining Technique would be useless.
Fortunately, as time passes and he continues to train in Basic Taijutsu, he can vaguely feel an improvement in his physical condition.
This, in turn, is gradually increasing his body's upper limits.
