After leaving a clone at the turtle's head, Uchiha Yoichi directly returned to the Waterfall of True.
Upon returning, it happened to be Kushina's tenth failed challenge against her dark self. Although this wasn't a real fight, continually challenging her dark self was mentally exhausting, leaving Kushina quickly out of breath.
"This, this is so difficult. She uses the exact same ninjutsu as me, and our combat habits are identical. I simply can't defeat her...Mr. Yoichi, is there any trick?"
Seeing Uchiha Yoichi return, Kushina quickly asked for advice; the words her dark self spoke earlier were too terrifying, about killing friends and family—she absolutely didn't want to do that.
Facing her dark side, Kushina finally admits the reality that she once truly had such thoughts. But now, Kushina wants to separate from and utterly destroy her dark self.
"I don't have any solutions. Either you completely eliminate her or accept her; there shouldn't be a third option, and this is your own issue. You're a mature ninja now; don't always think about relying on others."
Uchiha Yoichi spoke coldly, "I'm an advisor in the village now; I don't have much time to stay here with you, so you'd better resolve it quickly, or I'll activate the backup plan."
Upon hearing this, Kushina felt a chill in her heart and then muttered indignantly, "If it were you, you definitely couldn't deal with your dark self either, and your darkness might be...."
On hearing this, Uchiha Yoichi snorted coldly and then walked towards Kushina; she froze for a moment and then quickly rose to make way.
After Kushina made way, Uchiha Yoichi sat down, closed his eyes, and prepared to face the darkness within his heart.
However, after waiting for a while, he opened his eyes again and looked at his palm... why was there no reaction at all?
Seeing this, Kushina quickly asked, "Did you succeed?"
"No, this Waterfall of True has no effect on me."
"Why is that?"
"It's likely because I never hide my desires. Those who are somewhat informed know I want to kill Danzo; it's just that he's almost as good as dead now, so I let him go....
Dark or not, they all stem from unfulfilled personal desires that give rise to dark thoughts. My desires have been well satisfied, so why would I have a dark self?"
After finishing, Uchiha Yoichi glanced at Kushina and continued, "If now the Akatsuki Organization members are killed before you, avenging your profound hatred, or if Namikaze Minato is resurrected, the Nine-tailed no longer troubles you, and your childhood dreams gradually come true, would you still have a dark side?"
Kushina lowered her head. What Uchiha Yoichi said were exactly the deepest desires in her heart, and if they were all fulfilled, Kushina wondered how happy she would be.
"You clearly have the ability...."
"Here we go again, just because I have the ability must I help you? Why don't you strive to enhance your strength, annihilate the Akatsuki Organization, and then resurrect Namikaze Minato yourself?"
Uchiha Yoichi sneered, "I can tell you the method right now. Chiyo from the Hidden Sand Village researched a Forbidden Technique, One's Own Life Reincarnation, which can use one's life to resurrect the dead. If you want to learn it, I can arrange for the village to get it for you.
Once you master this Forbidden Technique, combined with the Reanimation Jutsu, you can resurrect Namikaze Minato. I've told you the method; the rest is up to your own effort."
Kushina fell silent, biting her lip and unable to speak for a long time.
She wasn't afraid of sacrificing her life; she was just worried Minato wouldn't accept being revived in this way, as Minato would certainly not want her to use her life to bring him back, and Kushina was also concerned about Naruto.
"The village is already gathering intelligence and information on the Akatsuki Organization, and as soon as there is intelligence, I will personally act to wipe out the Akatsuki Organization, but you'd better quickly resolve your own issues."
Uchiha Yoichi finished speaking and then tossed a Sealing Scroll to Kushina, containing some provisions for eating and clothing, even instruments for outdoor camping.
"You can stay here for now; don't worry about Naruto."
After speaking, Uchiha Yoichi turned and left; there was nothing significant left in the village. If there was, his clone could inform him instantly, and now he also had to continue training.
After Uchiha Yoichi left, Kushina lowered her head in silence for a while and then went back towards the Waterfall of True.
——————————————
Using clones for prolonged periods is indeed exhausting, but if it weren't for Uchiha Yoichi's training in the Spirit Secret Technique, it would really be hard to endure.
His state is almost the same as when Orochimaru simultaneously handles three research projects, training, village affairs, etc. The main point is that Uchiha Yoichi uses many clones, and digesting the training experience alone takes a lot of time.
The Waterfall of True didn't show his own dark side, as besides his desires largely being satisfied, it might also be related to Uchiha Yoichi's training in Spirit Secret Technique.
If it were ten years ago, during the time he was persecuted by Danzo, if Uchiha Yoichi had come to the Waterfall of True, his dark self might be harder to eliminate than anyone else's.
Now, his power is slowly growing and has reached the pinnacle of a ninja; the next enemy he faces is the Otsutsuki. Moreover, when facing the Otsutsuki, Uchiha Yoichi still has little fear in his heart.
Partly because he knows he has a long buffer time, and partly because Uchiha Yoichi has the confidence to surpass the Otsutsuki.
