First, the Gelel Stone is definitely not Chakra. This type of energy basically cannot be stored in external objects for a long time; even Chakra released by the human body quickly dissipates into the air.
Takuno had also sensed it using Kujaku Myōhō: Eye and the not-yet-fully-opened Mind's Eye of Kagura, and it contained no Chakra fluctuations.
Moreover, even if it were indeed Chakra, it would be useless to him, as Takuno also lacks the ability to absorb it.
The ability to absorb Chakra in Naruto is limited to only a few methods: either a special Ninja Tool like Samehada, the Rinnegan, or finally, the Dark Release Kekkei Genkai.
Takuno looked at the sparkling Gelel Stone in his hand. It seemed to be drawing energy from the Gelel Stone because of its proximity, but even a single Gelel Stone would eventually reach saturation.
Therefore, the only apparent use he had for it was to use the Gelel Stone to replenish the Gelel Stone's energy, and then use the Gelel Stone to strengthen his body's recovery ability and grant a certain physical boost during combat.
But the effect seemed to be limited to just that, and to fully unleash the Gelel Stone's power, he would need to implant it near his heart, just like Temujin.
Hence, it would be best to first experiment based on the records in the Book of Gelel to find the optimal method of embedding it; the heart is not something to tamper with lightly.
However, such simple usage would clearly be a waste of the Gelel Stone's power; using this much energy merely to supply the Gelel Stone is a complete overkill.
Takuno frowned, deep in thought, and finally, his eyes flashed.
If there really is no other way to use it, why not summon the Mini Ten-Tails?
He was certain that no matter what type of energy the Gelel Stone was, the Mini Ten-Tails would be able to devour it without issue.
"If the Mini Ten-Tails can do it, can the Chakra of other Tailed Beasts also be replenished?" After thinking of the Mini Ten-Tails, Takuno naturally thought of the other Tailed Beasts.
In fact, he still kept the Three-Tails' Chakra.
He had already found a way to cultivate the Three-Tails' Chakra, but because he had too many other tasks, and his Chakra was used for experiments and practicing Ninjutsu, he hadn't cultivated much of it yet.
If he could find a way to use the Gelel Stone's power to replenish Tailed Beast Chakra, it would definitely save a lot of trouble.
Furthermore, isn't this power, which is full of Yang Nature and Natural Energy properties, quite suitable for Tailed Beast Chakra?
Then he should take a portion of the lode back to study. If it can replenish Tailed Beast Chakra, that would be ideal.
If that truly fails, it wouldn't be too late to let the Mini Ten-Tails devour it, keeping only a small portion to replenish the Gelel Stone's energy.
After making this decision, Takuno began inscribing Sealing Jutsu around the area.
This way, even if the Gelel royal family came to inherit the Gelel Stone, they would be unable to utilize its power again.
Inscribing the Sealing Jutsu around such a large lake took Takuno a considerable amount of time.
After completing all this, and with the Gelel Stone fully charged with energy, he used Kujaku Myōhō: Wing to leave the sealed area and fly into the sky.
As he looked down upon the sealed area from above, he paused. He carefully examined this sealing location situated high upon the mountain, and then looked at the surrounding towering peaks.
At that moment, an idea popped into his mind.
Perhaps, this is the most suitable location for performing the Chimera Technique?
It is important to remember that when Hiruko merged the five bodies in the original story, he gathered three conditions: Heaven, Earth, and Man.
Heaven referred to the annular solar eclipse, when Natural Energy was most unstable, making it suitable for the forbidden fusion.
The Gelel Stone itself possesses the properties of Natural Energy. If he later used the Curse Mark obtained from Jugo to absorb and suppress Natural Energy, he would be able to create a suitable environment himself.
Earth referred to performing the ritual within a special barrier atop a high mountain, the purpose of which was to stabilize the flow of Chakra and provide the energy for fusion.
And this location is not only a high mountain itself but is also surrounded by peaks. As for the fusion energy, couldn't the Gelel Stone provide it completely?
As for Man, that refers to the corpse possessing the appropriate Kekkei Genkai.
He has not yet fully collected the Kekkei Genkai subjects he desires, but he is not in a hurry.
Furthermore, a small amount of leaked power from the Gelel Stone is enough to completely heal a severely injured person, and it could also stabilize his physical condition when he uses the Chimera Technique.
Seen in this light, this place could completely replace the location Hiruko specifically sought out that met the 'Heaven, Earth, and Man' conditions, becoming the site where he would perform the Chimera Technique in the future.
"It seems that I cannot feed it to the Mini Ten-Tails before completing the Chimera Technique fusion."
Takuno muttered to himself and made his decision. Locations suitable for the Chimera Technique are rare, and waiting for an annular solar eclipse would take far too long.
As for feeding it to replenish Tailed Beast Chakra, that is still necessary. Cultivating Tailed Beast Chakra doesn't need to be completed all at once, and the amount used is not significant compared to the energy of the entire Gelel Stone.
After deciding, Takuno calculated the time. He hadn't spent much time since leaving Konoha; things were progressing much more smoothly than he had imagined.
He remembered that Minato had told him to relax and travel outside for a while longer.
However, resting was out of the question. Since he had time, he needed to return to the experimental base to research the Gelel Stone.
With the Book of Gelel, he should be able to figure this thing out quickly.
Furthermore, after some thought, Takuno contacted the group who had helped him investigate the Gelel Stone and asked them to buy some local specialties for him in the Land of Rivers, which he would take back later.
The purpose, naturally, was to give them to Minato, to maintain good relations while also showing him that he had enjoyed his time in the Land of Rivers.
After finishing his thoughts, Takuno turned into a puff of white smoke and vanished from the Land of Rivers... reappearing inside the experimental base.
Takuno clenched his fist, then threw a punch, sensing the slightly enhanced strength; the degree of enhancement was rather ordinary.
He had now embedded the Gelel Stone near his heart, and with every heartbeat, its power circulated throughout his body.
But even though the Gelel Stone was fully charged with energy, the speed of this enhancement could only be described as average, requiring accumulation over time to see noticeable results.
However, having it is always better than not having it.
Takuno wasn't disappointed; this was the result he had anticipated.
According to his experiments, the Gelel Stone could be embedded in the heart, or it could simply be placed against the body, like Haido, and still exert a certain effect.
But to gain the same recovery ability as Temujin, it still needed to be embedded in the heart.
Additionally, Takuno snapped his fingers, and a striking bolt of lightning erupted in front of him, requiring no hand signs—this was the power belonging to the Gelel Stone.
In terms of power, it was similar to the Rasengan before it was enhanced by meteorite Chakra. Although decent, it was useless to him now, serving only as a temporary measure when he ran out of Chakra.
After the experiments were complete, Takuno straightened his clothes, preparing to head to the Land of Waterfalls.
While he was conducting the Gelel Stone experiments, the crows he had sent out had successively found Haku and Jugo!
