Shimizu Mitsuki had been in this world for almost five years; today marked his fifth birthday.
For others, this day might be slightly special, but for Mitsuki, it was the most important day, second only to the day of his Rebirth.
Because, when the clock struck midnight, his System would send him this year's birthday email.
And there was also a Heart of Wishes, plus tomorrow's login would complete a full year of sign-ins, earning him another Heart of Wishes as a reward.
Finally.
"Ding, you have a new email. The email will disappear in 365 days. Please check it in time."
It's here, it's here, it's here. The email content was always the same few lines.
"Dear Host, thank you for your support and companionship to the System over the past year. We hereby present you with a Heart of Wishes, wishing you a smooth new life."
After claiming the System's gift, and with the additional Heart of Wishes from the automatic sign-in completing a full year, Mitsuki's slightly trembling small hand clicked open the Wish panel.
The 10th consecutive Wish had a 100% success rate. According to the System, this Wish function was different from the gacha in some games in his previous life; a successful Wish would reward him with the skill most suitable for him.
Therefore, Mitsuki didn't need to worry about Wishing for some useless skill.
So, let the Wishing begin!
"Do you wish to expend 9 Hearts of Wishes for nine Wishes? Note, the tenth Wish is guaranteed to be successful."
"Confirm."
"9 Hearts of Wishes have been consumed. Wishing begins."
"Wish failed, Wish failed... Wish successful!"
"Congratulations, Host, you have obtained the Eye of the Heavens - Six Eyes."
Hmm? Six Eyes? Is this truly the most suitable skill for him right now?
Since he already drew it, he might as well open it and see.
Thinking this, Mitsuki opened the skill description.
"Skill: Six Eyes"
"Ability 1: 360-degree long-range vision"
"Ability 2: See through the principles of most Ninjutsu"
"Ability 3: Chakra trajectory tracking and prediction"
"Ability 4: Precise Chakra manipulation"
"Ability 5: Minimized Chakra consumption"
It had the style of the System panel, as minimalist as ever.
However, for describing the abilities, it was clear enough. These were Chakra-version Six Eyes. Not getting the Innate Technique Limitless was within expectations.
After all, Limitless and Six Eyes were two different things, and the System wasn't running some buy-one-get-one-free promotional event.
So Mitsuki didn't feel too disappointed or anything.
He took a mirror from the bedside drawer and examined his newly acquired Six Eyes.
Perhaps it was because his original pupils were blue; now, besides becoming a bit brighter, there didn't seem to be any change.
He briefly observed his surroundings. He didn't know until he looked, and when he looked, he was shocked. Mitsuki had never felt this way before. In his field of vision, a radius of tens of kilometers centered on himself was completely unobstructed.
This range, is it real or fake? Shimizu Mitsuki knew that in the Naruto World, there was a perception ability called Kagura Mind Eye.
Its perception range also extended tens of kilometers, but in terms of the information perceived, Kagura Mind Eye couldn't even compare to Six Eyes.
He wondered if it was because, compared to Cursed Energy, Chakra had physical energy in addition to spiritual energy, but Mitsuki felt that the burden on his brain wasn't very heavy.
In Mitsuki's eyes, he could freely choose whether to see through surrounding buildings and human bodies to view the scenes behind them, and he could also freely observe the Chakra within each person's body.
This ability was similar to the Byakugan, but its range was much larger than the Byakugan's. The effective detection range of an ordinary Byakugan was only one kilometer.
Although for an average Ninja, a one-kilometer detection range was already very impressive.
However, the gap between that and the tens of kilometers perception range of Six Eyes or Kagura Mind Eye was still very large.
Mitsuki suddenly wanted to see what Rin was doing at this time, but given Rin's self-discipline, she must have already gone to sleep.
So he turned his gaze towards the Nohara Clan. Oh? Rin wasn't asleep yet. She was holding an ugly shark doll, lying on her back on the bed, her cute little head hanging over the edge, seemingly talking to herself.
"Tomorrow is Mitsuki's birthday. Kento-san just passed away not long ago, so tomorrow, I absolutely cannot let Mitsuki feel lonely."
Rin suddenly sat up, as if she had thought of something.
"How about I stay over at Mitsuki's house tomorrow? Mom should agree!"
Whether Mrs. Nohara would agree was unknown, but at this moment, Shimizu Mitsuki discovered a drawback of the Six Eyes.
That was, he could only see Rin speaking, but couldn't hear her voice.
It seems necessary to learn lip-reading. By the way, do all Ninja of the Hyuga Clan know lip-reading? Or have they never considered it?
It shouldn't be, but the manga indeed didn't show this point. This is a topic worth researching.
For Mitsuki, the Six Eyes possessed the investigative information volume comparable to the Byakugan and the perception range of the Kagura Mind Eye. This ability seemed like it could play a significant role in war.
However, he hadn't enrolled in the Ninja Academy yet, and it wasn't his turn to go to the battlefield. When he did get to the battlefield, he would just disguise it as exceptional perception ability.
After experimenting with the first two abilities, Mitsuki looked at the last one: extremely precise Chakra control ability.
He thought for a moment. If there was one Ninjutsu that best demonstrated Chakra control, it would have to be medical Ninjutsu.
The regrettable thing was that he had never come into contact with medical Ninjutsu, and Kento didn't have any such Ninjutsu in his collection.
As for other Ninjutsu, Mitsuki actually thought of one.
That was the Rasengan.
In the manga, the Cultivate method for the Rasengan could be said to be the most detailed among all Ninjutsu, and each stage within it heavily tested Chakra control ability.
Thinking of this, Shimizu Mitsuki extended his hand, attempting to recreate a Rasengan. As described in the manga, he transformed his Chakra into a spherical shape, with wildly spinning Chakra inside.
As Chakra was released, a Zhan blue orb slowly appeared in Shimizu Mitsuki's hand.
Shimizu Mitsuki was a bit dumbfounded. It succeeded just like that? It couldn't be a fake, could it? He gently pressed the Rasengan in his hand against a corner of his bedside table.
Crack!
The corner of the table instantly shattered, the cross-section showing many irregular wooden splinters.
It was undoubtedly the real deal.
Looking at the destruction caused by the Rasengan, Mitsuki dispersed the Chakra in his hand. Such power from just a light touch meant it was indeed successful.
But he didn't feel much effort in creating the Rasengan. Is this the ultimate Chakra control ability?
Mitsuki could even feel that his Chakra consumption wasn't very high.
This indicated that there was not a single trace of wasted Chakra when he created the Rasengan.
"This is truly amazing. Then, the unsealed Lightning Release he casually made up when he and Kento were looking for topics between father and son, which involved channeling Chakra through metal weapons, could actually be developed."
That short sword might actually come in handy. Should he give it a name?
Unfortunately, whether in his past life or now, Shimizu Mitsuki had always been terrible at naming things.
After thinking about names for a while, Shimizu Mitsuki gave up. After all, his mind only came up with names like 'Frostmourne' or 'Fire's Delight'.
Shimizu Mitsuki was very satisfied with the Six Eyes he obtained this time, and he continued to tinker and research until very late before finally falling into a deep sleep.
