[The Origin Scroll of the Uzumaki clan has awakened, if you want to gain ownership over it beat the test it gives you, it can range from fighting the Sage of Six Paths to creating a new seal, good luck.]
Naruto read the message as his surroundings warped much like when he entered an ID, the surroundings changed into a completely empty white space.
'Kurama, I may need your help, so be ready.' Naruto said, and waited for Kurama to reply.
But Kurama never replied.
[The test of the scroll has to be completed entirely alone, your connection to the chakra beast Kurama has been cut off, your task has been determined.]
[The scroll has reviewed your ability and concluded that it does not need to test your physical capabilities, so it will test you in what you are good at, you are required to complete the seal that you have been trying to make, the seal to indefinitely keep a chakra construct and a soul alive, you have a time limit of 1 day, good luck.]
[Time left: 23:59:59]
'Well, fuck.' Naruto cursed in his mind.
There were a multitude of problems that needed to be fixed in order for the seal to operate smoothly, first of all it needed to create and stabilize chakra, and a lot of it too, the Sage of Six Paths had created the 9 Bijuu a similar method, the Bijuu are basically living chakra generators, Naruto would need to create something similar that was capable of holding and connecting a soul to it, or in this case remnants of a soul's chakra, it would need to be precise down to the millionth, a single error and the seal would implode upon itself, there was also the fact that Naruto had only 24 hours to figure this all out, he would need at least a few months just to figure out how a seal could absorb or create that much chakra and not explode, and then he would need a few more months to design a multi-layered seal to be able to control that much chakra, and then, and only then would he need to figure out how to keep the chakra of a dead person from dissipating, perhaps it would be easier to just become a master of death and yoink said soul back from the pure world.
'Well, they never said I couldn't use clones so I guess that'll be the only way I can do this.' Naruto doubted anyone, even the greatest master of Fuinjutsu to ever exist would be able to create such a seal within 24 hours.
So in a giant explosion of smoke thousands of clones appeared beside Naruto, he now technically had multiple years of work but he would need to dissolve and recreate each clone when they made a discovery, there was also the chance that they would all simultaneously explode as the seal became unstable, which had happened before, Naruto was lucky to have an inner world where he could cause as much damage as he wanted, Konoha would have been long gone if he had hundreds of clones make unstable seals.
So the grueling experience of creating seal after seal, thousands, if not millions of times started, Naruto focused fully on recovering chakra and creating more clones.
Like that 12 hours had passed, Naruto's chakra coils had actually started to strain, he must've created over a hundred thousand clones in those 12 hours, but hard work paid off, he managed to create a 12-layer seal that could create, absorb, and control chakra comparable to around half of the One-Tailed Bijuu, which would theoretically be enough to support.
Just looking at the seal would make someone's head hurt, hundreds of symbols were laid out in an intricate pattern in an area smaller than 5 square centimeters, even now thousands of clones were busy calculating and experimenting with the seal, but Naruto would not be able to continue this way, his body would simply give up, he would need at least 10 minutes of rest which could be detrimental, but it was better than collapsing for multiple hours, so Naruto forced himself into a meditative state for 10 minutes, his chakra coils strengthened themselves and his chakra filled up to the max.
'Alright clones, I feel confident that the seal will be able to create enough chakra to sustain at least one person, the next step is to figure out how to contain a dead soul's chakra and to convert our seal's stored chakra into that person's chakra to keep them alive, for now, we don't need them to become a physical construct it is enough if they can be sealed into me like Kurama, expect not physically but mentally, if that makes sense.' Naruto said telepathically, he was connected to all of his clones and could communicate using his thoughts.
'Boss, it really doesn't but with another 100k of us we'll probably figure something out, just keep creating us.' The clones responded telepathically.
Naruto sighed and the explosions restarted, throwing in an external source of chakra completely threw off the balance, so the clones started creating more and more explosions.
Hours slowly trickled by, 11, 10, 9 hours left, the clones were getting closer and closer to cracking the code to the seal.
Time continued, 8, 7 6, 5, 4 hours remained, by now Naruto started panicking slightly, the seal was now stable but it wasn't capable of recreating the external chakra source, they would need to create a whole separate seal that could convert the stored chakra into the external chakra.
Naruto and his clones could feel it, if they managed to figure out how to convert the chakra from one into the other they would be able to bring a soul that had chakra remaining on earth back to life.
3, 2, and finally only a single hour was left.
The minutes continued Naruto felt beads of sweat roll down his entire body, he hadn't taken a single second of rest and his body was extremely burdened, the Gamer System would only activate its regenerative abilities when Naruto was in a state of sleep which Naruto could only accomplish by specifically meditating like that, but that would mean losing precious time.
In the end only 10 minutes were remaining, the clock continued ticking, Naruto was starting to lose hope, it would take them at least another 30 minutes to come close to figuring out how to complete the seal, they would not make it.
At least, that's what Naruto thought.
'Boss! I fucking did it! I figured it out!' A clone screamed and immediately destroyed itself.
The experience entered the mind of every single clone and they immediately started testing what the clone had done, each came back with 100% success.
[Time remaining: 00:00:52]
Naruto glanced at the time and immediately entered his inner world, he couldn't see Kurama but he could still see the seal, if he tried ripping it off the cage it would activate the safety measures and Naruto would come face to face with his father's chakra.
So without hesitation Naruto ripped off the seal and he immediately sensed a chakra signature appear behind him, quite similar to his own.
Naruto turned around and came face to face with his father, they looked extremely similar, if Naruto wasn't enhanced by the Gamer System he would look pretty much like his father except with a slightly rounder face.
"Dad, I don't have time to explain what's happening, just trust me, if this works then I will be able to bring you and mom back from the dead, so don't interfere." Naruto said and ignored whatever his father said, he immediately summoned a brush and multiple liters of ink, he had 40 seconds left so he would need to do this fast.
He wouldn't be able to use the Scroll to instantaneously apply the seal so he would need to do everything by hand.
Naruto's hand moved at lightning-fast speed's, the first layer was done, chakra started being gathered by the scroll, 38 seconds left, the seal would instantly become unstable so with both hands Naruto started simultaneously applying two seals that would balance the first seal, 34 seconds left, the first seal wouldn't produce enough chakra so Naruto created two more that would instead of generating chakra absorb it, 30 seconds left, then he applied a single seal to both to keep them stable, 25 seconds left, this was enough to generate enough chakra to keep resupplying the external chakra source, now came the hard part, Naruto started drawing hundreds of symbols on top of the seal he had created, 15 seconds were left, Naruto connected the remaining chakra of his father to the seal and could immediately feel the chakra of his father become stronger, 10 seconds left, just as quickly as it regained its chakra it was losing just as much, it needed to be able to control and balance the chakra which is what the last seal was for, Naruto's hands moved faster than they ever had and he finished the last symbol of the seal, which immediately started glowing and absorbing chakra from the closest source which happened to be Naruto himself.
Naruto watched his chakra rapidly decrease, there was one last step left, he would need multiple hand seals to make his own chakra move smoothly into the seal so that it would finish in time.
Naruto went through 10 hand seals in less than a single second and shouted.
"Fuinjutsu: Chakra Anchoring Seal!"
Then everything went silent, Naruto held his breath, not daring to breathe.
[Congratulations, you have passed the Scroll's test!]
[Remaining time: 00:00:00:30]
With that Naruto sighed in relief and simply allowed himself to fall, not caring the slightest what the system or his father were telling him.
