? It turns out...
The real Ryūchi Cave is in another dimension...
Looking blankly at the purple hazy sky and the completely new world in front of him, Yu couldn't help but marvel at White Snake Sage's generosity.
"Hmm... It's really interesting that humans can defeat Shi Sun and Shi Yu at such a young age."
"Ryūchi Cave's Senjutsu, no one has been able to successfully practice it for many years. Maybe you will be an exception."
An ancient and erratic voice emanated from White Snake Sage, "Shi Sun Shi Yu, you two take him to Dragon Transformation Pool's place and try it!"
"Dragon Transformation Pool?"
After hearing White Snake Sage's words, the two injured snake immortals Shi Sun Shi Yu next to them suddenly looked anxious, "White Snake Sage! But this human being just..."
"What?!"
However, before Shi Sun Shi Yu finished speaking, White Snake Sage's golden snake eyes glared, and an extremely majestic and terrifying power suddenly surged from the huge white body, "You two, do you want to disobey my order?!"
"Of course I don't dare! White Snake Sage!!"
Facing the terrifying power that White Snake Sage suddenly exuded from White Snake Sage, the two snake immortals Shi Sun Shi Yu were immediately frightened. In desperation, Shi Yu turned his head and said to Yu next to him, "Human, come with me!"
As expected...
Seeing the scene in front of him, Yu became more convinced of his suspicions. Unlike Toad Clan, who was on the so-called righteous side like Mount Myoboku, the snake clan of Ryūchi Cave was obviously more on the evil and dark side.
Snakes have always been ruthless. There is no free lunch in the world. White Snake Sage can so easily agree to let him learn Ryūchi Cave and Senjutsu. Yu is not naive enough to believe that it is really because it appreciates him.
After about ten minutes of walking, passing countless giant Taiseki bamboo shoots towering into the sky, Shi Yu led Yu to a bottomless pool. There were many snake-shaped stone statues placed around the pool.
"This is Dragon Transformation Pool..."
"Ordinary chakra = mental energy + physical energy, and Senjutsu Chakra = mental energy + physical energy + Natural Energy. The power is several times or even dozens of times that of ordinary chakra, depending on the level of practice."
On the edge of the huge pool, due to White Snake Sage's order, Shi Yu's huge body was gradually coiled on the ground, and he began to explain to Yu the knowledge about Senjutsu.
"If you want to practice Senjutsu, you must first have a large enough amount of chakra. Secondly, you need strong will and control ability, and you need to perfectly control the three abilities to maintain balance, and then you can successfully enter Sage Mode."
"If you maintain a perfect balance of the three energies and truly exert the power of Senjutsu, your appearance will not change; if you cannot control the huge Natural Energy and take in slightly more than one-third of your own energy, your body will begin to turn into a snake; and when Natural Energy is far greater than the mental energy and physical energy, your body will transform into a part of nature, such as a stone."
Shi Yu said, pointing to the numerous snake-shaped stone statues beside Dragon Transformation Pool with his tail, "Have you seen these stone statues? They are all people who failed to practice Senjutsu in the past. If they cannot control Natural Energy or maintain balance, they will turn into stones like them."
"This is the huge risk you must take to practice Sage Mode. Are you sure you want to try it?"
After expounding his interests, Shi Yu looked at Yu, as if he wanted him to retreat in spite of the difficulties.
After listening to what Shi Yu said, Yu thought about it silently for a moment. In fact, he already knew the concept of Sage Mode, but after Shi Yu's explanation, he had a more intuitive feeling.
"No need to talk nonsense, let's start quickly!"
After thinking carefully for a moment, Yu made a decision directly. After all, with his current huge amount of chakra and near-perfect chakra control ability, the risk of practicing Sage Mode is naturally much smaller than that of other ordinary ninjas.
"Humph, in that case, I wish you success in advance."
"Anyway, no one has successfully cultivated Ryūchi Cave into Senjutsu for many years. Judging from the amount of chakra, you should have fully reached the standard."
Hearing this, Shi Yu snorted and looked Yu up and down. After the short battle just now, he could clearly feel that the huge amount of chakra on Yu's body had almost exceeded Kage Level's standards.
Indeed, although it is still not as good as Naruto Uzumaki and First Hokage Senju Hashirama, after the transformation of String-String Fruit's ability and his unremitting efforts, Yu's current chakra amount has exceeded the Kage Level ninja of the same level by several times.
"Start now, you go to Dragon Transformation Pool..."
"Follow the method I taught you, sit down and feel Natural Energy carefully, and then try to control them and fuse them with your own chakra..."
Saying Shi Yu asked Yu to sit down at Dragon Transformation Pool, and began to explain to him the specific method of practicing Senjutsu Chakra.
Following the method Shi Yu said, Yu slowly sat cross-legged next to Dragon Transformation Pool and closed his eyes to practice. At the same time, he summoned all Demon Puppet from the different space to guard around him.
If any abnormal situation occurs, Tyrant and General Winter, Demon Puppet controlled by Parasitic Thread, will immediately attack the enemy and protect Yu's body.
After sitting in silence for a while, through Observation Haki's powerful perception ability, Yu could clearly and accurately capture the fully rich Natural Energy of Ryūchi Cave, and then gradually absorb them into his body.
Because it was his first time to practice, he was worried that the huge Natural Energy would be too violent and difficult to control, so Yu did not dare to absorb too much, but carefully absorbed a small part of Natural Energy into his body.
"This is..."
But Yu seemed to have underestimated the ferocity of Natural Energy. He had just tried to absorb a small part into his body, but he did not expect that these huge Natural Energy around him would penetrate into his body crazily like they were all-pervasive!
"How could this happen?!"
The balance between the three forces of physical energy, mental energy and Natural Energy was suddenly destroyed by the huge and violent Natural Energy crazily injected into the body, and Yu's body immediately began to react.
First, his skin began to turn pale, and then a large number of white snake scales appeared on his body. A snake's tail gradually began to grow from his back, and a pair of white dragon and snake horns appeared on his head.
"Humph, it's true that the ignorant are fearless..."
"This is my first time practicing Sage Mode and I dare to absorb so many Natural Energy..."
Seeing that Yu had accidentally absorbed such a large amount of Natural Energy at once, his body had begun to gradually turn into a snake, and the violent Natural Energy around him was still pouring into his body. The Shi Yu next to him suddenly snorted coldly.
Obviously, in its eyes, it seemed to have seen Yu completely transform into a snake and then gradually turn into a stone statue and die.
"It's over... What a 'dragon' aura, I didn't expect that White Snake Sage would miss the mark this time, and your fate will be no different from those stone statues..."
Damn...
Do I have to turn into stone like them...
He didn't expect that practicing Sage Mode would be so dangerous. Feeling his body gradually transforming into a snake, and the violent Natural Energy that was constantly being injected into his body, Yu felt a strong sense of unwillingness in his heart.
