Five months.
That's the time Takara NEEDED to invest in this place to wrap everything up.
Examining the seal containing Kaguya and expanding his knowledge of Fuinjutsu.
Thoroughly inspecting the Energy Ship.
Extracting enough resources from the moon for his use.
Studying the Otsutsuki clan's puppets and integrating their technology into his own.
Locating and deciphering the content of a very ancient library, which had also not been cared for in a long time.
Who needs books when you don't have eyes to read them?
Cultivating wood from Toneri's flesh and hybridizing it with the remains of the Ten-Tails obtained from Takigakure.
Knowing how to evolve his Byakugan.
Setting the fragments of natural energy gem.
Creating a "wise puppet" albeit with limitations.
And with everything he achieved, he could finally send Sunagakure's identity and authority that they believed they had over him to hell. Not only did he use puppets to replenish life supplies as Toneri did to sustain himself during this period, without touching the reserves of his workshop, but he also sent some of them to secretly retrieve Maki's tomb.
He wasn't going to let her stay there when his defection was revealed; certain people might come up with... certain ideas against him.
It was nice to have Katsuyu's company, essentially acting as his assistant for much of his exploration, fascinated by the moon's hidden history.
Takara wasn't so stupid as to summon her to the moon from the planet, killing herself in the process due to the amount of chakra required over the distances. He simply went down to the cave and summoned a large-sized Katsuyu, which passed through the spatial passage with him and spread out through the lunar palace to make sure nothing was missed.
It was also quite useful to act as an informant since the world kept turning in his absence, and he needed to be alert to major movements. Especially if they involved his future targets or if Akatsuki decided to advance their plans.
The disappearance of Takigakure's tree and its Hero's Water reserve was evident and caused panic in the village, panic that a certain mint-haired girl seemed to take advantage of to vanish into thin air.
It's not relevant, but it's better for people to believe that the jinchuriki fled, like Utakata or Roshi, than to know that he ceased to be a jinchuriki.
Konoha is currently moving people everywhere, wanting to retrieve Naruto in a frenzy.
Or rather, wanting to retrieve their deterrent weapon inside him.
Jiraiya seemed to have been fighting Orochimaru frequently, shouting that he would bring him back to him and his new nephew when he wasn't thoroughly searching for Tsunade's traces, who seemed to have become invisible to the world.
Katsuyu didn't notice movements from Akatsuki, apart from a certain masked man who, upon hearing the new rewards offered in the underground market, seemed to be moving with quite intensity and motivation.
The best part was that there was no mention of the mobilization, surveillance, disappearance, or death of any of the remaining jinchuriki.
Namely, the two from Kumo and Iwa along with Gaara.
But back to the moon, the seal for Kaguya was an advanced work even a thousand years later. It was smart to check it before extracting resources since there were certain parts of the moon that couldn't be damaged or the seal would start to degrade quickly.
The study of Toneri's puppets was surely the briefest of all, as while they had some interesting innovations in the joints and their motor system, it wasn't complicated to integrate those improvements into his puppets.
The library was a nightmare, by far the worst part of it all, draining more time yielding fewer results. But some key results without which he wouldn't have been able to progress.
The scrolls were written in a special encoded form in which if you didn't have the Byakugan and the ability to unlock it, it would be impossible to read them. After successfully passing the encoding, he saw that the vast majority of the texts were written in a very ancient form, making it difficult to translate and extract information successfully.
More than one crumbled when touched, demonstrating their poor preservation.
It didn't help that many constantly focused on highlighting the superiority of the Otsutsuki lineage over humans, how they were the chosen ones, cooler, more handsome, more powerful, wiser, how they had the bigger one and all kinds of flattering babble that was essentially a way to stroke their ego and pride to compensate for their fragile self-esteem and deep-seated feeling of inferiority, as if they were the MCs of a Chinese fanfic!
He had to transcribe many by hand, to hand them over to Vegapunk Shaka to help him extract something useful. But seeing the progress, he had to stop for a few days to make five identical puppets to accelerate the screening process.
Forty percent of the library was useless propaganda!
He was so furious for wasting time because of it that he burned everything to ashes.
But at least he found key information he didn't know and that allowed him to use the Energy Ship to sublimate his Byakugan into Tenseigan, in exchange for the "death of the sun", which was the device brimming with the power of the ancestors' eyes of the moon and natural energy.
It was probably how Toneri hoped to achieve such a feat, but it served Takara's purposes gladly.
The only annoying part was that the consumption was terrible because at the end of the day, he still lacked lineage in his blood, so he kept his eyes in Byakugan state. Calculating, he estimated that he could only sustain them without a problem when he could unlock his powers over time, that is, after sealing at least three rebirth eggs of biju inside him.
The fragments of natural energy gems could finally be used and set in his equipment pieces, like the mask. This not only allowed him to expand his reserves and use the outer ones first without consuming his own senjutsu chakra but curiously, the pieces also seemed to transform into more dynamic forms when this was done, as if the equipment itself entered its own sage mode to support him.
Even Katsuyu was a bit puzzled by this event, but she attributed it to the presence of Ryumyaku within Takara.
Taking advantage of being already in the workshop, he used the new wood to try to make new puppets, but it was quite difficult to work with, and the results were mixed.
The time to return to hunting had come.
