While planning to seize the basho fan, Fūmori Masaki was thinking about how to use this treasure of the Six Paths Sage. In the manga, Darui and Tenten had both used the treasure, but it absorbed a massive amount of Chakra, leaving them nearly exhausted after just a few uses.
You have to understand, in the setting, Darui possessed a powerful Chakra incomparable to ordinary people, and even he could not use the treasure multiple times, which shows how harsh the conditions for using the treasure are.
According to the setting, using the treasure requires a massive amount of Chakra, so mortals cannot use it; only descendants of the Sage like Kinkaku and Ginkaku can easily use the treasure.
The two are likely descendants of Ashura, so it is inevitable that they have powerful Chakra. However, seeing how Darui couldn't even stand steadily after using the treasure once, even if their Chakra were incredibly powerful, Kinkaku and Ginkaku should still feel somewhat drained after using the treasure so many times.
However, the result was that Kinkaku and Ginkaku remained energetic, and the Tailed Beast Chakra on their bodies showed no signs of weakening. Was their Chakra truly so vast that even multiple absorptions by the treasure could not exhaust them, or were there other reasons?
Fūmori Masaki recalled that in another world, there was a saying that treasures would recognize their owners. As a treasure passed down by the Six Paths Sage, could it also have some affinity for its descendants?
Is it possible that the absorption of Chakra is reduced because of this? In that case, it would better fit the claim that only descendants of the Sage can easily use the treasure.
Thus, after obtaining the basho fan, Fūmori Masaki immediately went to find Satomi. Satomi was also a descendant of Ashura and possessed vast Chakra herself; even he could not compare to her in terms of quantity after drinking the spring water. Regardless of whether his guess was correct, at least Satomi would certainly be able to use the treasure.
After holding the basho fan together with Satomi, the two looked at each other. Satomi nodded gently, then immediately injected her own Chakra into the basho fan and swung the fan. To help, Fūmori Masaki also injected Senjutsu Chakra into it.
The moment the treasure was used, Fūmori Masaki felt his Chakra pouring into the basho fan at an astonishing speed, making him feel as though it couldn't be stopped until his Chakra was completely exhausted.
Fortunately, this was only a momentary illusion for Fūmori Masaki; the injection of Chakra stopped quickly, and at the same time, a violent wind was stirred up by the swing of the basho fan.
"What!" Kinkaku was greatly shocked, his pupils shrinking rapidly. Although he was shocked in his heart, his movements were not slow. He immediately formed the hand seals for Lightning Release, and a flash of lightning collided with the violent wind. The lightning shattered upon contact, and the remaining violent wind blew onto Kinkaku.
The biting wind was as sharp as a knife, and wounds of various sizes immediately appeared on Kinkaku's body. He completely ignored them—anyway, under the effect of the Nine-Tails Chakra, these minor injuries would soon recover—what truly shocked him was the fact that Satomi had used the treasure.
"This is impossible!" Ginkaku, who was to the side, watched this scene, equally unable to believe it.
"Mortals cannot use the treasure; even if they could, they would inevitably have to pay a huge price." Kinkaku said in a low voice, his gaze turning to Satomi, "Could this woman be a descendant of the Six Paths Sage just like us?"
Seeing that the treasure had successfully unleashed a Wind Release, Fūmori Masaki looked at Satomi's expression and asked, "Satomi, are you okay? Is your Chakra exhausted?"
"Hm? No." Satomi shook her head, "You said this might be a treasure of the Six Paths Sage, so I thought it would definitely consume a lot of Chakra, but it turned out to be less than I imagined."
"Is that so." Fūmori Masaki said. It seemed his guess was correct; the treasure did indeed treat descendants of the Sage favorably. A treasure that would require a huge price for ordinary people might be as easy and natural to use in the hands of the Sage's descendants as an ordinary weapon.
Then, he shifted his gaze to Kinkaku and Ginkaku and said, "Satomi, the next one is Lightning Release."
"Okay." Satomi said, gripping the basho fan tightly with both hands.
Just as Kinkaku and Ginkaku were still hesitant and suspicious about Satomi's status as a descendant of the Sage, the others attacked once more. Danzo, Hiruzen Sarutobi, and Satomi simultaneously unleashed their Doton. The Fire, Wind, and Lightning Doton combined together, turning into a scorching pillar of fire, with a large amount of electric arcs surrounding it.
Kinkaku felt the immense power within the combined Ninjutsu and dared not be careless. He hurriedly gathered all his Chakra, gave a loud shout, and a bright red flash of lightning burst out, flying toward the pillar of fire like a spear.
Meanwhile, Ginkaku on the side had not yet recovered from the fact that Satomi had used the treasure. Actually, it wouldn't have been useful even if he had recovered; after all, having lost the basho fan, he was unable to use Ninjutsu.
With a loud bang, blinding light filled the entire field of vision, followed by a violent storm. Even with the Nine-Tails Chakra on their bodies, Kinkaku and Ginkaku could not block it and were sent flying backward. They didn't know how many trees they had broken, and even the trees that weren't hit fell in the gale that swept everything away.
When the shock of the explosion slowly subsided, Kinkaku climbed up, covered in dust, and the Nine-Tails Chakra on his body had disappeared. He coughed heavily and hurriedly looked for the figures of the enemies.
However, apart from the large areas of scorched and shattered ground and the fallen trees, Kinkaku did not see any figures. Intuition told him that those Konoha Ninja had already run away, rather than hiding to prepare for a sneak attack.
Kinkaku did not expect such a result. Not only did he fail to kill a single person, but he also had his treasure stolen. For him, who was proud of his status as a descendant of the Sage, it was simply a humiliation.
At this moment, he heard Ginkaku's coughing sound beside him. He turned his head to look and saw Ginkaku climbing up. He was instantly furious and stepped forward, slamming a heavy fist into Ginkaku's face.
Ginkaku was knocked directly to the ground. He covered his face, looking at Kinkaku in terror, and said, "Kin, Kinkaku, you..."
"What do you mean 'you'!" Kinkaku scolded unceremoniously, "What exactly are you doing? To actually let the treasure be stolen by others, are you still my brother!"
Hearing this, Ginkaku dared not reply. He had indeed let the basho fan be stolen by the enemy. He carefully glanced at Kinkaku and said, "Sor, sorry, Kinkaku."
"What's the use of saying sorry!" Kinkaku punched Ginkaku again. The force of this punch was great, causing Ginkaku's cheek to swell up. He just heard him yell, "How could I have such a stupid brother as you!"
Ginkaku was arrogant in front of other Kumogakure Ninja, but in front of his own brother, he could only nod and agree, because he was the older brother, and it was taken for granted that he could say whatever he wanted to his younger brother. Kinkaku also thought so; he felt that hitting his brother like this was for his own good—only when it hurts will he learn his lesson.
"Lord Kinkaku, Lord Ginkaku!" From not far away, the voices of others came. Kinkaku turned his head and saw a team of Kumogakure Ninja running over, "Are you alright?"
"I'm fine. Why are you here so late?" Kinkaku asked with an unpleasant expression.
The leader of the team hurriedly replied. It turned out that not long ago, the Second Hokage of Konohagakure had led his subordinates to retreat. Because the Second Raikage had to help the Kumogakure Ninja who had been ambushed while going to assist Kinkaku and Ginkaku, he did not choose to pursue. Instead, after forcing the Konoha Ninja in those ambush locations to leave, he stayed on the spot to take care of the injured personnel.
With the retreat of the Konoha Ninja, the Barrier and the rock walls no longer had any need to exist. Concerned for the safety of Kinkaku and Ginkaku, the Second Raikage immediately sent people to check on the situation.
"Seeing that you two are fine, Lord Second will surely be very happy." The captain said with a smile.
"Happy? Yes, he must be secretly laughing in his heart, laughing at our current state." Kinkaku sneered coldly, only feeling that the Second Raikage was being hypocritical. He had no interest in continuing to talk to this Kumogakure captain and left with Ginkaku.
