Naruto tried to use his Observation Haki to sense the Great Toad Sage's inner thoughts, but he didn't get any useful information.
It was too old, it didn't even have the energy to think much.
"Gama Tora, I also saw the prophecy of you entering Naruto's body."
A little toad wearing what looked like four silver bracelets came to the Great Toad Sage's side.
"What?"
Gama Tora looked surprised, then realized why the Great Toad Sage had called him.
"Give the Fourth Hokage's seal to Naruto."
"If Great Grandpa says so, I guess I have no choice."
Great Grandpa?
Naruto stared curiously at Gama Tora, and suddenly its body stretched out. Its original silver bracelet body turned into a large scroll!
"This is the key left by the Fourth Hokage to open and close the seal on your stomach. With it, you can even completely release Nine Tails' power. Just press your hand on the square," Gama Tora said.
Naruto nodded and walked forward, pressing his hand on the square on the scroll. The next moment, he felt something enter his mind.
"Is this the key to unlocking Nine Tails' seal?"
Now, with this method, he could completely unlock Nine Tails' seal.
However, there were still two layers of security left by the Fourth Hokage.
So even with this 'key,' he couldn't easily unlock Nine Tails' seal.
Thinking about it, Nine Tails was pretty pitiful. Escaping was harder than 'Andy'!
Leaving the Great Toad Sage,
Shima Sage said she was going to cook, and Fukasaku took Naruto to learn Sage Jutsu.
Toad Oil Waterfall.
A strange waterfall with many toad statues.
"Before learning Sage Jutsu, we need to know what Sage Jutsu is."
Fukasaku stopped in front of the waterfall and said to Naruto, "Sage Jutsu is using the Chakra you've trained, plus the natural energy you absorb from outside, to create newer and stronger Chakra, and then using it!"
"With the help of Sage Jutsu, whether it's Ninjutsu, Genjutsu, or Taijutsu, it will be greatly enhanced!"
Naruto nodded, signaling Fukasaku to continue.
"To train Sage Jutsu, you need to combine your inner mental energy, physical energy, and external natural energy to train Chakra. You should know your inner mental and physical energy well, but you've probably never heard of natural energy, right?"
Fukasaku jumped onto a huge toad statue, acting profound. "Natural energy exists in the world, and you need special methods to sense and use it!"
After saying this, Fukasaku placed his frog hands on the statue, and with a sudden burst of strength, he lifted the frog statue, which was dozens of times bigger than him!
But looking at his strained appearance, it seemed very difficult.
"How about it? This is the power of Sage Jutsu combined with natural energy!"
"It's okay."
"..."
Fukasaku was almost so angry by Naruto's calm comment that he dropped the statue!
"Don't think this statue is light. Even Little Jiraiya couldn't lift it without Sage energy!" Fukasaku said quietly.
"Is it heavy?"
Naruto appeared in front of Fukasaku at some point, and used one finger to lift the statue that he was struggling to hold up.
"O... One finger lifted it? And it doesn't even look difficult!"
Fukasaku's shocked toad chin looked like it could fit an ostrich egg. "What terrifying power... It's a monster!"
Naruto tossed the statue up, casually threw it to the ground, and said calmly, "Should we hurry up and train Sage Jutsu?"
"O... Okay!"
Fukasaku adjusted his emotions and said, "To train, you need to first sense the existence of natural Chakra, and to sense natural Chakra, you need to use toad oil."
Fukasaku came to the Toad Oil Waterfall, dipped a little toad oil, and said to Naruto, "Hold out your hand."
Naruto listened and gave his hand to Fukasaku, who then applied the toad oil to the back of his hand. "To be honest, with your strength, I can't imagine how strong you'll become after learning Sage Jutsu... This toad oil has the power to attract natural energy. As long as you put this oil on your body, natural energy can enter your body. If you train for a long time, your skin will gradually sense natural energy!"
As the toad oil circled on the back of his hand, Naruto clearly felt a surge of energy enter his body.
He was about to carefully sense it when he noticed his palm changing.
His original human palm had turned into a frog palm!
"Don't worry, this is normal. People who can't master natural energy well might turn into frogs, but..."
As he spoke, Fukasaku took out a club from somewhere and whacked Naruto on the back of the head.
But Naruto subconsciously turned into an element, causing Fukasaku's club to pass right through him.
"What?"
Fukasaku looked at Naruto with a shocked expression. "What is this?"
"My ability, just a subconscious reaction," Naruto explained.
"This... Can you control it? If I don't knock the natural energy out of your body, you'll turn into a frog!" Fukasaku said anxiously.
"I can, I'm controlling it now," Naruto said.
"Okay, then I'm going to hit you!"
Fukasaku quickly hit Naruto on the back of the head with the club, but it wasn't what he expected!
The club didn't knock the natural Chakra out of Naruto's body. Instead, it made a crisp sound!
Fukasaku: "..."
"Looks like you can't break my defense?" Half of Naruto's face had turned into a frog, and his voice was a bit frog-like, but he wasn't worried at all.
"I'm going to hit you with Sage Jutsu, so bear with it!"
Fukasaku didn't dare to delay any longer, and he gathered natural Chakra in his hand, ready to hit Naruto again!
But Naruto grabbed the club in his hand.
"No need, I've already mastered them!"
"Wha... What?"
Fukasaku was stunned, then he was shocked to see the frog transformation on Naruto's body disappear, and eye shadow appeared around his eyes!
"This... How is this possible? Perfect Sage Mode?"
Naruto ignored Fukasaku and carefully sensed the natural energy within his body.
Full Level Chakra Control!
Whether it was his own Chakra, Nine Tails' Chakra, or natural Chakra!
As long as it entered his body, he could completely control it!!!
