After Naruto got home, he copied the ninjutsu scroll, put it away, and waited for the System to turn it into ninjutsu.
Although it would take a long time, there would be no shortage of ninjutsu now.
After all the work, he tidied the room and went to bed early, and waited for the next day.
...
At seven in the morning, Naruto woke up.
"System, is it possible now to upgrade all those conditions met in the storage?"
Naruto sat on the bed and asked expectantly.
[Upgrad Started]
[20,000 copies of Mangekyō Sharingan have been upgraded to Eternal Mangekyō Sharingan (Kyōka Suigetsu, Dark World, Susanoo)]
(Tl/n: Kyōka Suigetsu means Mirror Flower, Water Moon; is an illusion-type Zanpakutō spirit that had once belonged to Sōsuke Aizen.)
[20,000 Byakugan have been upgraded to Tenseigan]
[20,000 points Namikaze Minato Chakra has been upgraded to the one-half soul of Namikaze Minato]
[20,000 points of Uzumaki Kushina Chakra has been upgraded to one-half of Uzumaki Kushina's soul]
"yessss!"
"However, the souls of Minato and Kushina… I almost forgot about them."
Naruto frowned and looked at the next two lines.
Should I bring them up?
"System, can you continue to save these things?"
[Eternal Mangekyō Sharingan can continue to be stored and upgraded to Rinnegan]
[Tenseigan cannot be upgraded yet]
[The souls of Namikaze Minato and Kushina cannot be stored further]
"Hmmm. Then bring out the eyes, I'll try it first…but will it upgrade my eyes directly or should I need to…"
Naruto asked worriedly, he was afraid to take out his eyeballs, and then have to change his eyes.
[The original eye is directly upgraded and replaced]
"That's good to hear, btw, can I try it? Then take it back and store it?"
[Yes]
"Then do it!"
This was Eternal Mangekyō and Tenseigan!
It would be a pity not to try them out first.
Naruto closed his eyes to be on the safe side.
Then he felt a sudden energy flow in his eyes, slowly flowing.
[Extraction successful]
"Done?"
Naruto opened his eyes and walked to the mirror.
"There is no difference?"
[Please use it according to the normal usage method]
"..."
I had no experience using Sharingan and Byakugan ok?
"Let's try sending Chakra to the eyes..."
Naruto focused Chakra on his eyes, and saw that his blue eyes began to change, the right iris turned light blue, and the pupil was black, which was no different from the Tenseigan Naruto had seen in his previous life.
Then there was his left eye, a smear of scarlet emerged from the pupil, occupying the entire eyeball like a vortex, the pupil was red, followed by a black ring, and the outermost was also a black ring, the difference was that there were six tomoe surrounding the innermost ring like a star.
"Eternal Mangekyō Sharingan..."
Naruto stared at his left eye obsessively.
And he also knew that there were three abilities in this Eternal Mangekyou Sharingan.
The first was the illusion 'Kyōka Suigetsu', which could firstly control the spirit of others, and secondly, control the five senses of the other person, making them completely believe that the appearance, shape, quality, touch, and even smell of a certain object was real.
"Wasn't this the skill of Aizen's Zanpakutō in Bleach, right? It seems that it can also make enemies kill each other. Although it is not as OP as forcibly changing the will of others, it should be one of the strongest illusions, at least better than Tsukuyomi."
The second ability was a space-time ninjutsu called 'Dark World', which can open a space called 'Darkness', which is pitch black and silent, even the sound of a heartbeat couldn't be heard, but Naruto could change the environment.
Once anyone was pulled into this space, they will completely lose their senses, only their consciousness will be left, and they will also feel fear because they wouldn't know whether the time was flowing or not. A second outside may be an hour, a day, or even a year for the people inside.
If someone stays long enough, they might even turn into a walking dead.
This ability was very similar to Obito's Kamui, making him immune to physical attacks, and space transfer.
The difference was that Naruto could turn himself into a shadow, enter and exit the darkness at will, or move in space through the darkness or the shadow of others.
In short, it was a very 'BUG' ability!
Now Naruto had one more hidden card!
The third ability was the Susanoo.
Shisui had used the Susano with one-eyed, forcibly using it.
And Naruto had the combination of two Mangekyō in one with two abilities, and there was no problem with using Susano, which was perfect.
Naruto turned his head and looked around with his newly acquired eyes.
In the beginning, it was very uncomfortable, as everything seemed to have double images.
With the Sharingan closed, it was much better just to use the Tenseigan, 360-degree vision without blind spots. To be honest it was also uncomfortable, as he felt like he had been short-sighted for many years! He could see everything more clearly, even the dust floating in the air like it was under a microscope! But after some adjustment, it's not that bad.
"This feeling is great!"
Then Naruto tried Sharingan again.
Compared with the insight of the Tenseigan, Sharingan was slightly worse, but it was better at capturing dynamic and high-speed moving objects.
Of course, there were also the basic capabilities of copying and seeing Chakra.
...
He decided not to go out today, and spend the rest of the time getting used to the eyes so that he won't have issues when he uses them again in the future.
By the way, he also wanted to try the abilities of the Eternal Mangekyou Sharingan!
This was a good thing that was very suitable for sneak attacks!
Space transfer, even if not as fast as the Flying Thunder God, Naruto was satisfied!
[It is detected that the host has acquired the seven attributes of Chakra wind, fire, water, earth, lightning, yin, and yang, and the upgrade will start. The upgrade time will take ten days, and the rewards for stored items during the period will remain the same.]
"Upgrade?! Seven attributes Chakra?"
Naruto was taken aback.
"Oh, I forgot, when I got the Sharingan and Byakugan before, it seemed that I also got the Uchiha bloodline and the bloodline of the Hyuga clan... So if I have the Sharingan, I should also have the Yin Chakra as well, right? "
"Should I upgrade it now? Do I need my eyes back?"
[Temporarily unrecoverable, the upgrade has started...]
"..."
Naruto was speechless, if he knew that there was going to be an upgrade, he would have not used these eyes.
Fortunately, he had also obtained the bloodline inheritance, so he didn't have to worry about the Sharingan being closed, otherwise, he would not be able to explain it.
If he said that it was an eye injury? He would be sent to the Konoha Hospital in minutes.
If he said it was because he read Kakashi's Book and got his eyes damaged? Would anyone believe it?
"Well, since the system has started the upgrade, why not take advantage of these few days and make good use of my new abilities~"
Naruto suddenly looked forward to the next few days.
