The originally sunny, cloudless blue sky was suddenly filled with violent winds. Dark clouds materialized out of nowhere, gathering rapidly. Lightning danced among the clouds, and the rumble of thunder echoed...
"Wow... the Great Toad Sage is amazing!" Naruto looked up and exclaimed in awe.
Kageyama Kogetsu's expression was calm, his mindset unperturbed.
When chakra reached a certain level, it could influence celestial phenomena through natural energy. A typical example was the Ten-Tails.
The senjutsu chakra in the Great Toad Sage was indeed massive, but it was still far inferior to the Ten-Tails.
The reason he could cause such drastic changes in celestial phenomena was not only because senjutsu chakra was closely related to natural energy, but mainly because this was Mount Myoboku.
The Great Toad Sage had stayed in Mount Myoboku for over a thousand years and was all too familiar with the natural energy here. It could be said to be his domain. It wouldn't be so easy anywhere else.
With his chakra volume, if Kageyama Kogetsu entered Sage Mode, he could also influence natural energy through senjutsu chakra, and thereby influence celestial phenomena.
Sensing the drastic changes in the environment, Madara Uchiha and Obito Uchiha looked around. After exchanging glances, their eyes fell on the figure atop the temple of Mount Myoboku.
"Hey, what do you mean by 'pathetic'?" Madara Uchiha asked expressionlessly.
Hearing this, Black Zetsu was very anxious.
He was afraid the Great Toad Sage would reveal the origins of the Ten-Tails, eventually implicating his mother, Kaguya Ōtsutsuki. But he couldn't speak up, as it would easily arouse suspicion.
Learning Sage Mode and contacting these old monsters was truly a terrible idea!
"Isn't walking an evil path pathetic?"
To avoid affecting the final outcome, the Great Toad Sage didn't reveal key information and just made up a reason.
Black Zetsu breathed a huge sigh of relief, thinking that even after a thousand years, Mother's deterrence still existed!
"Tch... evil path? What does a big toad like you know?" Madara Uchiha scoffed.
Obito Uchiha didn't say anything, but he felt the same way.
"You said the ancestor of the Uchiha clan was Indra, the eldest son of the Sage of Six Paths. Then who is the ancestor of the Senju clan?" Madara Uchiha asked curiously.
"The ancestors of the Senju clan and the Uzumaki clan were both Asura, the second son of the Sage of Six Paths."
This wasn't key information, so the Great Toad Sage didn't hide it.
Hearing this, Madara Uchiha suddenly realized. No wonder he and Hashirama were so powerful, and the ninja of the Uchiha and Senju clans were so outstanding. It turned out the Sage's bloodline also played a part.
Wait... something's wrong. The ancestor of the Uchiha clan was the eldest son, and the ancestor of the Senju clan was the second son.
Why couldn't he beat Hashirama?
Was he really inferior to Hashirama?
With this thought, Madara Uchiha couldn't help but feel quite depressed.
Madara and Sasuke were also unlucky. Most of the time, the reincarnate of Indra was stronger than the reincarnate of Asura, and the latter needed help from others.
However, Hashirama Senju and Naruto Uzumaki were special cases who could win without help from others.
"Who is the ancestor of the Hyūga clan?"
Belonging to a dōjutsu clan like the Uchiha, and seeing the power of Kageyama Kogetsu's Tenseigan, Madara Uchiha developed an interest in the Hyūga clan that he never had before.
"Hamura Ōtsutsuki, the younger brother of the Sage of Six Paths."
"That's enough. You can leave now."
Seeing the Great Toad Sage issue an eviction order, and with Kageyama Kogetsu and Naruto present, making it impossible to achieve their goal, Madara Uchiha and Obito Uchiha left.
"Thank you, Lord Hokage, Little Naruto, and Little Jiraiya, for coming to help."
"No need to be polite. Given the relationship between Konoha and Mount Myoboku, we should help each other."
"Indeed. Fukasaku, Shima, please entertain our esteemed guests well on my behalf. I need to personally set up some measures to prevent the enemy from returning for a sneak attack."
"No need for entertainment. There are still many things waiting for me to handle in Konoha."
"Naruto will go back with me. Senior Jiraiya, in these special times, go find Lady Tsunade and return to the village together."
"Alright," Jiraiya said solemnly.
"Great Toad Sage, farewell."
"Goodbye, Lord Hokage."
After the three left, the Great Toad Sage personally took action, setting up Mount Myoboku with Yin-Yang arts and Yin-Yang magic circles from ancient times.
With the boost of the Yin-Yang magic circles, the Great Toad Sage's strength would be enhanced to a certain extent.
At the same time, the natural energy in the magic circles would automatically manifest various attacks against enemies, including mental and physical attacks.
This way, even if Madara Uchiha and Obito Uchiha returned, Mount Myoboku could buy enough time to call for help.
Before the birth of the chakra system, native forces like Mount Myoboku practiced Yin-Yang arts, manipulating natural energy.
However, during the time around the planting of the God Tree, the vast majority of native cultivation forces in this world were wiped out by Isshiki Ōtsutsuki and Kaguya Ōtsutsuki.
The inheritance of Yin-Yang arts was almost completely exterminated. Except for forces with long heritages like Mount Myoboku, traces of Yin-Yang arts could hardly be found elsewhere.
Mount Myoboku's Yin-Yang arts inheritance wasn't particularly powerful; it was just a small force in ancient times.
Most small, medium, and large native forces were wiped out. Mount Myoboku was a lucky survivor.
After the God Tree absorbed the natural energy and the battle between Kaguya and her sons, the total amount of natural energy in this world decreased significantly.
Mount Myoboku's Yin-Yang arts inheritance wasn't that strong, and they were traumatized by Isshiki and Kaguya, so they actively chose to embrace the chakra system.
Combining natural energy and Yin-Yang arts, they created Mount Myoboku's unique Sage Mode and senjutsu, gradually growing to this day.
Now, the only existence in the entire Mount Myoboku who knew Yin-Yang arts and Yin-Yang magic circles was the Great Toad Sage.
In the entire ninja world, the number of existences who knew Yin-Yang arts and Yin-Yang magic circles wouldn't exceed the fingers on one hand!
Although ninjutsu was mainstream now, Yin-Yang arts still had their unique advantages. Those who didn't understand them could easily be ambushed.
...
After returning to Konoha, Kageyama Kogetsu didn't stop. He tore through the void and went directly to Shikkotsu Forest in the ocean to meet the Katsuyu Sage.
Having not seen her for a long time, Kageyama Kogetsu found that the Katsuyu Sage's body had grown even larger, as imposing as the True Several Thousand Hands!
With the Katsuyu Sage's main body, spitting acid to melt a small mountain would probably be a piece of cake.
The saying "big is beautiful, big is strong, big is good" sometimes really made sense.
"Katsuyu Sage, long time no see," Kageyama Kogetsu said with a smile, hovering in mid-air.
"It's Lord Hokage. Is there something you need from me?"
A gentle and melodious voice, completely inconsistent with her size, rang out, pleasant to the ear. Her two huge, slender tentacles swayed gently.
"I'm here to give the Katsuyu Sage a warning. It's like this..."
Kageyama Kogetsu recounted what had happened at Mount Myoboku and then explained the motives of Madara Uchiha and Obito Uchiha.
"That's the situation. I suggest the Katsuyu Sage avoid the brunt of it to prevent losses."
With the Katsuyu Sage's abilities, she was much harder to kill than the Great Toad Sage and the White Snake Sage.
Even if Madara Uchiha and Obito Uchiha joined forces, it would be basically impossible to prevent even a single division of the Katsuyu Sage from escaping...
"Thank you for your kindness, Lord Hokage. But with my size, it might be difficult to hide..." the Katsuyu Sage said somewhat troubledly.
An old monster who had lived for a thousand years wouldn't put herself in danger and ruin her cultivation for the sake of face.
Kageyama Kogetsu smiled confidently. "It's fine. I'll find a secret place to summon the Katsuyu Sage to."
"After a while, the Katsuyu Sage can dispel the Summoning Technique and return."
With Kageyama Kogetsu's chakra volume, summoning the entire Katsuyu Sage wasn't difficult.
"That would be greatly appreciated."
