Faced with the Katsuyu the Sage's earnest offer, Kōki couldn't refuse again and finally nodded in agreement.
"Now let me witness the power of the new Sage Mode!"
After Kōki expressed his wish, the Katsuyu the Sage followed suit and stated his own request.
After all, she was quite curious about this new Sage Mode.
Of course, even if the Katsuyu the Sage didn't say anything, Kōki himself wanted to know just how powerful this suddenly created Sage Mode really was.
Led by the Katsuyu the Sage, Kōki arrived at a clearing next to the forest.
This place is flat and open, making it ideal for practicing techniques.
Therefore, upon arriving at this place, Kōki did not hesitate. His Senjutsu Chakra flowed rapidly within his body, and his hands quickly Hand Seals.
In an instant, countless trees sprang up from the ground. In just two seconds, a lush and dense forest filled the open space in front of Kōki.
That's right, he used " Wood Release: Deep Forest Emergence Technique ".
However, unlike the usual Wood Release: Deep Forest Emergence Technique, this time he used Senjutsu Chakra to activate Wood Release.
The effects of using Senjutsu Chakra were also very noticeable; Kōki felt that both the power and range of the Advent of a World of Trees had been significantly enhanced. If the original power was ten, then the current power was definitely one hundred.
What pleased him even more was that his Chakra depletion had been minimized.
Previously, he could only use his own Chakra to perform the Advent of a World of Trees Technique about ten times. But after using Sage Mode, he can use it fifty times, or even a hundred times. After using Sage Mode, he can also be called Chatonra.
He can easily use even the Wood Golem and Wood Dragon Technique, which he had previously considered his trump cards. He can even use the ultimate Wood Release technique Sage Art: Wood Release: True Several Thousand Hands.
However, he will still be exhausted after using his ultimate move. After all, due to the limitations of his basic Chakra, fusing Senjutsu Chakra won't be too exaggerated. He still has a long way to go to reach Hashirama Senju's level.
But in any case, as long as he doesn't use this ultimate Wood Release technique, he can use other Wood Release Ninjutsu as much as he wants and for as long as he wants, basically without any pressure.
To put it simply, once he activates Sage Mode, he can easily defeat five of his previous selves.
" Kōki, what's wrong?" The Katsuyu the Sage, who was observing Sage Mode, was stunned when he saw Kōki use only Wood Release and asked curiously.
"It's nothing. I was just marveling at the power of this Special Sage Mode. After using it, I couldn't even feel Chakra pressure when using Wood Release Sage Mode. Sage Mode is just too strong."
After responding to the Katsuyu the Sage, Kōki stopped spacing out.
It continues to demonstrate the power of Sage Mode.
This time, he didn't use Wood Release, but instead used ordinary Five Elements Release Technique. However, even simple Five Release Technique unleashed tremendous power under the enhancement of Senjutsu Chakra.
In an instant, towering waves, majestic earth dragons, and scorching flames appeared in Kōki's hands.
"Boom!" "Boom!"
A constant roar echoed across the field in front of Kōki.
The once lush forest was shattered by Kōki's relentless bombardment, leaving huge cracks and scorched marks on the ground.
It looked as if it had been ravaged by war.
Even the Katsuyu the Sage watching from the sidelines was filled with amazement!
"Is this the improved Sage Mode you've done, Kōki? It's definitely much stronger than the regular Sage Mode."
Although the Katsuyu the Sage had anticipated the power of the modified Sage Mode, he ultimately realized he had underestimated it. This special Sage Mode enhanced Ninjutsu more than three times over the previous Sage Mode.
After destroying and leveling the entire forest he had created with Senjutsu Chakra, Kōki was finally stopped by the Katsuyu the Sage from continuing to demonstrate Sage Mode.
"That's enough, Kōki. I can already feel the power of your improved Sage Mode."
In the past half hour, the Katsuyu the Sage has come to understand the power of the new Sage Mode.
It was indeed several times stronger than the normal Sage Mode, and it's unclear whether this was due to Kōki's special constitution or because the Special Sage Mode was truly that long-lasting.
Despite unleashing Senjutsu Sage Mode repeatedly for half an hour, Kōki was still able to maintain it without experiencing any depletion of Senjutsu Chakra and having to exit Sage Mode.
This left the Katsuyu the Sage both curious and confused about the improved Sage Mode.
Upon hearing the Katsuyu the Sage's order to stop, Kōki also halted his men's relentless bombardment, though a hint of lingering satisfaction appeared on his face.
It has to be said that the ability to use Ninjutsu without worrying about Chakra consumption was incredibly satisfying; the exhilarating feeling was something he had never experienced before.
During those half hour, he truly experienced the joy of being a magic turret; the feeling of watching things in front of him being destroyed and shattered was irresistible.
" Lady Katsuyu, is that enough? I feel there's still so much more to show."
The Katsuyu the Sage was speechless as he watched Yuki, who was still not satisfied and was filled with destructive Kōki. They had already destroyed an entire forest, and they still weren't done with it.
At the same time, the fanatical expression on Kōki's face made her speculate about Kōki's Sage Mode: "Alright, Kōki. You've done enough. Now I have a question for you. Why can your Sage Mode last for so long?"
It's worth noting that a normal Sage Mode can only last for about five minutes, but Kōki's Sage Mode can last for thirty minutes, which is more than six times longer than a normal Sage Mode.
Furthermore, sensing the remaining Senjutsu Chakra within Kōki's body, the Katsuyu the Sage estimated that Kōki could maintain Sage Mode for about ten more minutes.
In other words, Kōki's improved Sage Mode can last for about forty minutes, which is an astonishing number.
This means that even without the Katsuyu's assistance, Kōki can complete the entire battle using Sage Mode. In other words, the Special Sage Mode almost eliminates the short duration of Sage Mode.
Upon hearing the Katsuyu the Sage's question, Kōki also snapped out of his reverie of the exhilarating experience of using the magic turret.
As his rationality returned, he also discovered that his Sage Mode was unusually prolonged.
However, he himself didn't know how this situation came about. So he directly replied to the Katsuyu the Sage, "I'm sorry, Katsuyu the Sage, I don't know why this happened either."
The Katsuyu the Sage wasn't surprised by Kōki's answer. She had only asked the question to provide more evidence for her own guesses. Since Kōki was unclear about her own situation, she could only continue to speculate.
"If I'm not mistaken, when you were forming Senjutsu Chakra, you increased the proportion of Natural Energy, bringing your body closer to nature. In this state, Natural Energy constantly flows into your body, allowing you to maintain Sage Mode. In a way, Kōki, you are truly remarkable."
At this point, the Katsuyu the Sage expressed considerable praise for Kōki, but then changed the subject. "However, don't think that maintaining Sage Mode indefinitely is a good thing. By changing the proportion of Natural Energy absorbed in order to increase the power of Sage Mode, you've inadvertently extended the duration of Sage Mode."
"But what you don't know is that the human body cannot remain in Natural Energy for extended periods, which is why Sage Mode has a time limit. This is why, in order to extend the duration of Sage Mode, the system evolved to involve cooperation between humans and summoned beasts."
"Now that you've abandoned this weakness, you're spending more time close to nature, which means you're getting closer to being assimilated by nature. Over time, your mind will become extremely irritable, and if some accident occurs and the Natural Energy within you gets out of control, your body will immediately petrify, and then no one will be able to save you."
"Therefore, Kōki, your Sage Mode is a double-edged sword. Using it for too long will cause you to be assimilated by Natural Energy without you even realizing it. So if you value your life, you must control the time you spend using Sage Mode."
In closing, the Katsuyu the Sage's tone was filled with a strong warning. She didn't want the amazing Kōki to fall victim to Natural Energy; she wanted to see just how far Kōki could ultimately go.
Upon hearing the Katsuyu the Sage's warning, Kōki's pupils contracted, and his previously happy expression stiffened.
He never imagined that the Sage Mode he created would pose such a great danger.
He originally thought that maintaining Sage Mode for as long as possible would be better.
It turns out that Sage Mode has this flaw.
Then, he thought of Jūgo, the boy who was corrupted by Natural Energy. The problem he was facing now was very similar to Jūgo's temper becoming irritable after being affected by Natural Energy.
That makes sense when you think about it. Natural Energy can be harmful to the human body, even though Sage Mode is a harmless way to utilize Natural Energy.
However, in his excessive pursuit of power, he inadvertently abandoned the protection of his human body when changing to Sage Mode. This is probably the price he paid for pursuing power.
Perhaps the more power one desires, the greater the danger one faces; this is the only fairness the world bestows upon all beings.
"I understand, Katsuyu the Sage. I'll be careful."
After saying that, Kōki deactivated the Sage Mode that was still active on his body.
Since Sage Mode has such dangers, he must treat it with caution.
After deactivating Sage Mode, Kōki's previous urge to vent vanished instantly.
This made Kōki realize that he had indeed been affected by a high concentration of Natural Energy.
He was immediately filled with dread. If he had maintained this "Sage Mode" for an extended period on the battlefield, causing emotional fluctuations, it would have been dangerous.
The first essential quality of a ninja is to maintain absolute calm in battle; irrelevant emotions can easily lead to negative consequences.
Having discovered that prolonged use of Sage Mode would cause significant changes in his emotions, Kōki immediately set a limit for his use of Sage Mode.
Thirty minutes!
Kōki estimated that the erosion of his body by the Natural Energy would last for about thirty minutes, meaning that his Sage Mode could only be maintained for thirty minutes. After that time, he would have to deactivate Sage Mode, otherwise, he would be in danger.
Kōki's emotional changes did not escape the notice of the Katsuyu the Sage. After seeing the look of fear on Kōki's face, the Kōki Katsuyu the Sage continued to warn him.
"I believe you are aware of the dangers of the improved Sage Mode, and I hope you will use it with caution."
After hearing the Katsuyu the Sage's warning, Kōki nodded seriously.
Just as he was about to continue speaking, it suddenly occurred to him that there was a third step in cultivating the ordinary Sage Mode, wasn't there? Could he use the Katsuyu's cooperation to extend the duration of the Special Sage Mode?
Kōki was really unwilling to give up on extending the Special Sage Mode.
"Wait, Katsuyu the Sage. I'd like to ask if I can resolve the issue of Special Sage Mode by cooperating with Little Katsuyu. I'm wondering if I won't be affected by Natural Energy if Little Katsuyu is around."
Kōki's thinking makes sense. For example, when he reaches the 30-minute limit of Sage Mode, he can deactivate Sage Mode and Katsuyu following him enter Sage Mode again. In this way, he can use Sage Mode indefinitely.
Unfortunately, the Katsuyu the Sage gave him a direct negative answer, " Little Kōki, you still don't understand what I mean. The limitation of your Sage Mode is due to the excessively high concentration of Natural Energy in your body. For example, your hand can withstand a temperature of around 50 degrees Celsius for thirty minutes, and during those thirty minutes, you think your hand is intact, but in fact, the cells inside have already been damaged."
"Your modified Special Sage Mode is like this. The excessive Natural Energy puts considerable stress on your body's cells, even causing damage. You can tolerate it for a short time, but problems will arise in the long run. Therefore, the ideal state for your Special Sage Mode is to use it once every seven days, for only thirty minutes each time. Only in this way will you not be affected by the high concentration of Natural Energy."
After the Katsuyu the Sage's blunt explanation, Kōki had no choice but to give up.
The meaning of the Katsuyu the Sage is quite simple: high concentrations of Natural Energy can harm the human body, and the recovery cycle of human cells is seven days. Therefore, to continue using it, one must wait for the body to recover from the damage.
At the same time, Kōki also had a question: if he could improve the resilience of his body's cells through some methods, could he eventually become unaffected by Natural Energy and maintain Special Sage Mode state indefinitely?
However, Kōki did not raise this issue with the Katsuyu the Sage.
Because this involves human experimentation, it could easily expose his thoughts on human experimentation.
Who knows if the Katsuyu the Sage might find this objectionable? I don't want it to affect his goodwill towards the Katsuyu the Sage.
He was hoping to get even more good stuff from the Katsuyu the Sage.
"Now I really understand, thank you Katsuyu the Sage for clearing up my confusion. I will restrain myself from using this Sage Mode in the future. But I'm wondering if I could switch to regular Sage Mode after using this Sage Mode. After all, regular Sage Mode shouldn't have too much of an impact on my body, right?"
This was also the alternative solution that Kōki came up with when he was thinking about how to overcome the limitations of the Special Sage Mode.
There was no way he could give up Sage Mode; the boost to his power was too great.
Since the special Sage Mode is unavailable, let's use the regular Sage Mode as a temporary solution.
He doesn't mind as long as it improves his strength.
The Katsuyu the Sage was now at a loss for words, wondering if they were really going to force the timing of their Senjutsu to work.
However, Kōki's words made her think about it seriously, and she finally concluded that this method could indeed work.
