"What exactly are you trying to do..."
Kushina's tone was initially very fierce, as she was forcibly taken away from Naruto, her anger and inner darkness erupted.
However, after seeing Uchiha Yoichi's gaze, Kushina's attitude and tone softened.
Faced with someone so powerful that could easily kill her, Kushina instinctively felt fear, so her tone naturally couldn't remain fierce.
Especially since Kushina didn't understand Uchiha Yoichi's intentions, coupled with the fact that the Nine-tailed once said Uchiha Yoichi would kill her, which made Kushina even more frightened.
After flying for several hours, Uchiha Yoichi had already arrived over the sea. After searching for a while, he finally confirmed the location of Turtle Island.
The Hidden Cloud Village kept Turtle Island's location very secret. They believed this hidden sanctuary was unknown to anyone, and Turtle Island could move across the sea... But unfortunately, Uchiha Yoichi dispatched Anbu to gather targeted intel.
He waited within the Land of Lightning for over ten days and finally cornered a Hidden Cloud Jonin, who happened to have been stationed on Turtle Island.
When the Jinchuriki trial wasn't happening, Turtle Island was just a paradise for wild animals. Although it was guarded, there were no more than a squad stationed.
"Fortunately, the Hidden Cloud Village hasn't put up a barrier..."
After observing carefully for a while, Uchiha Yoichi directly controlled Susanoo to land on Turtle Island.
Without any significant events occurring, the Hidden Cloud Village indeed wouldn't raise a barrier, as enveloping the entire Turtle Island with a barrier consumed a lot of Chakra daily. With only a liaison squad left on Turtle Island, it wasn't worth wasting that Chakra.
Wood Clone Jutsu!
Uchiha Yoichi created a Wood Clone, planning to have it control the Hidden Cloud Ninja here first, then he said to Kushina, "Let's go, follow me."
"What are you planning to do?"
Still very cautious, Kushina tugged at her collar, but upon seeing Kushina's actions, Uchiha Yoichi sneered inwardly. If he wanted to act, even ten Kushinas wouldn't escape.
Uchiha Yoichi began walking forward. Seeing him silent and in a strange place, Kushina, after some inner struggle, had no choice but to follow.
Soon, the Wood Clone transmitted its memories, indicating that the Hidden Cloud Squad on Turtle Island had been killed. Next, they only needed to control this giant turtle to let it swim away, and the Hidden Cloud Village wouldn't be able to find their Jinchuriki Power Trial Sacred Land.
Very quickly, Uchiha Yoichi brought Kushina to the Waterfall of True. To be honest, he couldn't tell what was so special about it, but it could reflect a person's inner darkness.
"Go sit over there. This is the Hidden Cloud Village's Waterfall of True. You should remember the Jinchuriki training method I brought back for you last time. The Hidden Cloud's Jinchuriki must first face their true selves here before proceeding to the training grounds behind the waterfall for cultivation..."
Uchiha Yoichi turned his head to Kushina and said, "You and I have severely offended the Nine-tailed, so don't think about becoming a perfect Jinchuriki. But the darkness in your heart is so intense that you even wanted to kill me once. I can't ignore that..."
"I didn't!"
Upon hearing this, Kushina immediately said loudly, although she felt a bit guilty when saying it; because, at times, she indeed had such thoughts.
"Lying to me is useless. Only you know what's in your heart. Without Asura's Chakra, even a slight touch of the Tailed Beast Chakra's negative emotions is hard to shake off, especially the Nine-tailed, which harbors the most hatred among the Tailed Beasts..."
"Alright, no more words. Go sit over there."
Seeing that Kushina still wanted to argue, Uchiha Yoichi, not wanting to continue the dispute, pointed to the stone in front of the waterfall and said.
Upon hearing this, Kushina reluctantly walked over, sat by the stone, and soon quieted down.
In less than a minute, Kushina collapsed backward, gasping heavily, though she quickly supported herself with her hands; facing one's inner world doesn't take long, after all, it's not a real battle.
After seeing the darkness within at the Waterfall of True, Kushina became a bit more composed, turning to Uchiha Yoichi and saying, "I... I saw my dark self... But I was defeated by her. Is there a way to eliminate her?"
"Figure it out yourself, no one can help you with this; but if you can't overcome it... Sorry Kushina, I'll make sure Minami takes good care of Naruto."
Uchiha Yoichi said with a somewhat intimidating tone, "I won't allow someone with malice towards me to live in this world, especially if they can approach my family as a friend."
Kushina's face froze, then she cursed inwardly.
Still, she snorted coldly, turned around, readying herself to continue battling her darker side.
After leaving a Wood Clone to watch over Kushina, Uchiha Yoichi then prepared to move to the turtle's head.
He planned to use an Illusion Technique to control the turtle and move it towards the sea of the Land of Fire, allowing him to shuttle back and forth using the Flying Thunder God Jutsu, saving more Chakra than using Susanoo for travel.
After finding the giant turtle's head, Uchiha Yoichi used the Mangekyo Sharingan to control it, then directed it to swim towards the sea of the Land of Fire.
This was the northernmost sea of the Land of Lightning. It would take about ten days to swim to the Land of Fire's sea, but the Hidden Cloud Ninja couldn't react in time. By the time their next batch of replacement Ninja Squad arrived, the giant turtle would have left the Land of Lightning's borders.
