The medicinal pill obtained by Akako Koizumi not only possessed the capability to enhance power and extend lifespan, but its greatest feature was its ability to maintain perpetual youth.
That alone held an irresistible allure for any woman.
On the whole, witnessing such remarkably precious rewards caused the hearts of the anime girls holding the Diary to race with excitement, and a deep sense of envy began to bloom within them.
At this moment, a single thought crossed all of their minds: to receive a reward, their names had to be mentioned by Hayashi Rin.
The best possible scenario was to have their names brought up by him as often as possible.
The more rewards they accumulated, the greater the likelihood that they would eventually obtain what they truly desired.
Yet, how could they get Hayashi Rin to mention their names frequently?
The most effective method was to cross his path and make appearances before him as often as possible.
To make that a reality, they first needed to locate him, get close to him, and earn his favor.
Thus, the most urgent priority right now was to track down Hayashi Rin.
…
On the other hand, Hayashi Rin was also brimming with anticipation.
Having written so much content today, the reward he stood to gain was bound to be exceptionally gratifying.
He closed his notebook and muttered under his breath: “System, claim the rewards.”
[Ding, the Host has completed the second Diary entry.]
[Rewards: Fivefold Physical Limit of Ordinary Humans, One Kakashi Chakra, Eight Inner Gates Formation Technique (Cosmo Improved Version).]
Hayashi Rin sat straight up, caught in a wave of pleasant surprise.
‘This system is ridiculously generous and amazing!’
‘The starter rewards alone are already this overpowered!’
‘I feel like I’ve just become invincible right off the bat.’
‘Keep it cool.
I need to stay composed and avoid getting arrogant.’
After calming his surging excitement, Hayashi Rin carefully inspected the details of his rewards.
The fivefold physical enhancement granted him physical constitution equivalent to five times the upper limit of a normal human.
His arms now boasted an raw lifting and striking capacity of a thousand kilograms, his top movement speed easily exceeded fifty meters per second, and his physical resilience, self-healing factor, and immune system were elevated far beyond the boundaries of ordinary mortals.
With a physique like this, even without relying on any martial arts techniques, he was no longer a weakling in this world.
Furthermore, this fivefold physical boost was an all-around enhancement across every physiological metric, including a fivefold multiplication of his total lifespan.
That fact made Hayashi Rin’s heart beat with wild excitement.
It meant that right now, he had secured a natural lifespan reaching four to five hundred years.
Long life and immortality were dreams pursued relentlessly by countless emperors, rulers, and nobles throughout history.
As for One Kakashi Chakra, it was universally understood as the standard benchmark of Kakashi’s baseline Chakra reserves.
All of these foundational enhancements served as the system’s supporting package to ensure Hayashi Rin could execute the Eight Inner Gates to their absolute potential.
The Eight Inner Gates granted by the system was the supreme physical technique famously wielded by Might Guy in the world of Naruto.
To unleash such a technique, possessing superhuman physical durability and adequate Chakra reserves were absolute prerequisites.
Although Kakashi’s Chakra capacity was frequently used as a standard baseline for comparison, it was still noticeably larger than Might Guy’s personal reserve.
Moreover, because Chakra extraction required the harmonious blending of spiritual energy and physical stamina, the system had thoughtfully complemented it with the fivefold human physical limit upgrade.
Even more crucial was the fact that the Eight Inner Gates Formation Technique provided by the system was a modified edition—specifically dubbed the Cosmo version.
This particular detail had briefly made Hayashi Rin wonder if this Crossover Anime World also incorporated the Saint Seiya universe, as the presence of Cosmo would otherwise remain unexplained.
However, based on the information he had gathered so far, high-power battle worlds like Saint Seiya or Dragon Ball were entirely absent from this universe.
This left a lingering trace of curiosity in Hayashi Rin’s mind.
Nevertheless, he quickly tossed those doubts aside, as the system’s Cosmo-modified Eight Inner Gates offered truly breathtaking advantages.
As was widely known in the Naruto universe, opening the Eight Inner Gates up to the fourth gate, the Gate of Wound, would begin tearing the user’s body apart.
Opening it all the way to the eighth gate, the Gate of Death, would undoubtedly lead to permanent maiming or outright death.
Yet, this Cosmo-modified Eight Inner Gates from the system suffered from no such drawbacks.
The moment the user unlocked the fourth gate, the Gate of Wound, the Human Body’s Hidden Treasure—otherwise known as Cosmo—would be awakened simultaneously.
That capacity represented the boundless, dormant potential residing within the human frame.
Because the Human Body’s Hidden Treasure could endlessly replenish depleted vitality and instantly regenerate bodily strain at any given second, executing the Eight Inner Gates would never inflict lingering backlash upon the user.
Even when opening the eighth gate, the Gate of Death, as long as the duration remained within the allocated safety threshold, the user’s body would suffer neither damage nor crippling aftereffects.
This safe operational timeframe would continuously scale upward as his physical resilience, Chakra reserves, and overall power levels progressed.
Based on his current physical constitution at the fivefold tier and his reserve of One Kakashi Chakra:
Hayashi Rin could unleash the eighth gate, the Gate of Death, once every thirty days, with a maximum safe duration of five minutes.
Within that five-minute window, his body would sustain zero structural damage.
Once used, the technique required a one-month cooldown to fully reset.
The seventh gate, the Gate of Wonder, could be unleashed once every ten days, carrying a fifteen-minute safe duration without harming his body.
The sixth gate, the Gate of View, could be opened once every three days, with a safe operational limit of half an hour.
The fifth gate, the Gate of Limit, could be activated once per day for up to a full hour.
The fourth gate, the Gate of Wound, could be engaged three times daily, lasting up to two hours each time.
As for the first three initial gates, they could be opened virtually without restriction, accessible whenever he pleased.
Reading through the full description, Hayashi Rin was thoroughly elated.
The fact that the first three gates of the Eight Inner Gates could be engaged freely meant he could multiply his raw combat power up to eight times at a moment’s notice.
A fivefold base physical limit multiplied by eight times raw strength equaled forty times the peak human threshold, allowing a single strike of his to deliver upwards of eight tons of destructive force.
Suddenly coming into possession of such monumental power made it difficult for anyone to sit still.
Hayashi Rin felt an overwhelming urge to test the actual limits of his newfound capabilities immediately.
After disguising his appearance, he stepped out of his residence.
His initial plan was to find a secluded, uninhabited spot to test his power.
However, he quickly realized that the Land of Ke shared similarities with Japan, where streets were dense and urban populations were exceedingly high, making it nearly impossible to find a quiet space within the city proper.
In the end, Hayashi Rin took a three-hour taxi ride out toward the forest on the city’s outskirts until he finally reached a remote, untouched wilderness.
He muttered to himself: “It’s a good thing the geography of Japan is dominated by rolling hills and mountain ranges.
Otherwise, tracking down an empty stretch like this would have been a real headache.”
After confirming that there was no one in the vicinity, Hayashi Rin launched himself upward and dashed toward the deeper depths of the forest.
With just a single leap, Hayashi Rin cleared over thirty meters through the air.
The sheer capability of his fivefold human physical limit left him deeply impressed.
The instant his toes grazed the forest floor, his entire body shot forward like a howling gale, causing the dense trees around him to blur and recede at blinding speed.
The sensation was akin to riding aboard a high-speed express train.
At full sprint, his speed could easily reach one hundred and eighty kilometers per hour, effortlessly matching the pace of a bullet train.
This gave Hayashi Rin a far clearer understanding of his current physical capabilities.
