Yamanaka Tohru's Sage Mode

After that, Yamanaka Tohru continuously poured Nature Energy into his Yin Seal, and it took nearly 10 days for the Nature Energy in the Yin Seal to reach saturation.

The amount of external Nature Energy attracted by Yamanaka Tohru's special Nature Energy varied each time, so it took three days longer than expected.

Even so, Yamanaka Tohru couldn't help but marvel at the horror of nature. It would take a person at least two years to accumulate Chakra in the Yin Seal, but it only took 10 days to fill the Yin Seal with Nature Energy.

Jiraiya looked disdainfully at Yamanaka Tohru's statement. In his opinion, Yamanaka Tohru pouring Nature Energy into the Yin Seal and a Ninja accumulating Chakra to fill the Yin Seal were completely different concepts.

First, Nature Energy is inexhaustible, while a Ninja's Chakra is limited. Second, Chakra can release Ninjutsu, which is much more effective than Nature Energy. In Jiraiya's view, the Yin Seal filled with Chakra was much more practical than the Yin Seal filled with Nature Energy.

When Yamanaka Tohru poured a huge amount of Nature Energy into the Yin Seal, he gradually understood Jiraiya's words. As he said, Nature Energy is inexhaustible.

Because no matter how much Nature Energy Yamanaka Tohru consumed in Mount Myōboku, he couldn't feel any reduction.

After the Yin Seal reached saturation, Yamanaka Tohru entered Ice Release, releasing the Nature Energy in the Yin Seal, and the Nature Energy flowed from Yamanaka Tohru's arm.

Yamanaka Tohru released Water Disturbance, and the Ice Seal did not consume Chakra; he released Water Dragon Bullet, and the Ice Seal still did not consume Chakra.

After that, Yamanaka Tohru closed the Nature Energy output of the Yin Seal. He had just opened the Yin Seal for about 10 minutes, and the Nature Energy in the Yin Seal had consumed about one-fifth of it, most of which dissipated in the air, and only a small part was used by Yamanaka Tohru.

In other words, Yamanaka Tohru spent 10 days accumulating Nature Energy, and he could use Ice Release without consumption for about 50 minutes.

The problem of Ice Seal Ninjutsu consuming a lot of Chakra, which had troubled Yamanaka Tohru for nearly 4 years, was finally perfectly solved.

After solving the Ice Release problem, Yamanaka Tohru decided to start working on cultivating Sage Mode.

Sage Fukasaku couldn't enter Sage Mode, mainly because he absorbed external Nature Energy too quickly.

Yamanaka Tohru didn't have time to fuse Body Energy, Mental Energy, and Nature Energy in a 1:1:1 ratio to produce Sage Chakra.

So Yamanaka Tohru wanted to try to fuse Body Energy and Mental Energy of the same size as that special Nature Energy to see if he could produce Sage Chakra. If he could produce Sage Chakra, he would open the Yin Seal to replenish the consumption of Nature Energy.

In the original story, Sage Fukasaku said that Ninjas can easily distinguish Body Energy and Mental Energy because of the use of Ninjutsu. Yamanaka Tohru could also do it after cultivation.

He guided Body Energy and Mental Energy of about the same size as that Nature Energy, controlling the three to fuse with each other.

After the three energies reached one-third of their respective amounts, they began to slowly merge. A special Chakra was born from Yamanaka Tohru's body.

"Is this Sage Chakra?" Orange-red eye shadow began to appear on Yamanaka Tohru's face. Because he used Mount Myōboku's toad oil to sense Nature Chakra, the Sage's face was the same as Naruto's.

Yamanaka Tohru felt the changes in the Chakra in his body. As mentioned in the original story, the amplification effect of Sage Mode was indeed very obvious. Yamanaka Tohru's perception ability and physical flexibility were greatly enhanced.

Yamanaka Tohru opened Lightning Release Chakra Mode, and at the same time unlocked the Yin Seal. After experimenting with Lightning Release Chakra Mode released by Sage Chakra, the speed and power were greatly improved, completely exceeding the speed of Ice Lightning Mode.

"[Sage Art: Raikiri]" Yamanaka Tohru poured Sage Chakra into Raikiri, and Raikiri's size and power were improved, and even the sound of the technique became inaudible.

Might Guy said during the Chunin Exams in the original story that Chidori was a technique created for assassination, but whether it was Chidori or Raikiri, it was mostly used for thrusting.

And after Yamanaka Tohru learned Chidori and Raikiri, he realized why this technique could not be used for assassination. Because the sound of the technique was too loud.

The Chidori technique is named after the sound it makes, like a thousand birds chirping. Although Raikiri has been improved, it is not perfect.

Yamanaka Tohru added Sage Chakra to Raikiri, and Raikiri can now be used for assassination.

After about 1 minute, Yamanaka Tohru's Sage Mode was automatically released. As Sage Fukasaku said, Yamanaka Tohru was too young and his Chakra was insufficient. Although the Yin Seal replenished the consumption of Nature Energy in his body, his own state could not maintain Sage Mode for long.

After his physical condition recovered, Yamanaka Tohru entered Sage Mode again. This time, he did not release Raikiri or open Lightning Release Chakra Mode, and Yamanaka Tohru's Sage Mode lasted less than 2 minutes.

After another experiment, Yamanaka Tohru used Raikiri, Lightning Release Chakra Mode, and Chidori Blade three techniques in Sage Mode. Sage Mode only lasted less than 1 minute.

After determining the duration of his Sage Mode, Yamanaka Tohru stopped cultivating. He needed to ask Sage Fukasaku about the combat methods related to Sage Mode.

The next day, Yamanaka Tohru found Sage Fukasaku, who was guiding Jiraiya's cultivation.

Jiraiya still couldn't find a way to integrate with nature. Sage Fukasaku couldn't help with this, so he could only let Jiraiya understand it himself.

"Tohru-chan, what's the matter?" Sage Fukasaku had already sensed Yamanaka Tohru's arrival.

"Sage Fukasaku, I want to learn the combat methods of Sage Mode from you." Yamanaka Tohru directly stated his intention.

"Tohru-chan, didn't I say that! You can't enter Sage Mode, what are you?"

Before Sage Fukasaku could finish speaking, Yamanaka Tohru entered Sage Mode. Sage Fukasaku and Jiraiya both stared at Yamanaka Tohru in stunned silence.

Sage Fukasaku was shocked by Yamanaka Tohru's relatively perfect Sage Mode. He originally determined that Yamanaka Tohru could not enter Sage Mode, but he didn't expect Yamanaka Tohru to succeed, and Sage Mode was much more perfect than Jiraiya's.

After that, Sage Fukasaku noticed the Nature Energy flowing out of Yamanaka Tohru's Yin Seal.

"Tohru-chan, are you absorbing the Nature Energy in this Sealing Jutsu?"

Yamanaka Tohru did not reveal the special Nature Energy in his body to Sage Fukasaku. Therefore, when Sage Fukasaku noticed the Nature Energy flowing out of Yamanaka Tohru's Yin Seal, he imagined that Yamanaka Tohru's method of controlling Nature Energy flowing into his body was relying on this Sealing Jutsu.

Yamanaka Tohru nodded without speaking.

"Kid, how long can your Sage Mode last?" Jiraiya asked.

"2 minutes without using any Ninjutsu."

"Tohru-chan, you have too little Chakra. It's better to use Sage Mode less in the future. Wait until you grow up and have enough Chakra before using it."

"Yes, Sage Fukasaku."

"But Tohru-chan is really a genius, to be able to think of this kind of method to control Nature Energy flowing into the body." Sage Fukasaku exclaimed.

"Old man, you're wrong. It's thanks to me, the genius, for helping this kid rewrite the Sealing Jutsu formula that he was able to enter Sage Mode." After saying that, Jiraiya laughed arrogantly.

"Jiraiya-chan, you can't even enter Sage Mode yourself, why don't you go and work harder on your training?"

"Yes, old man." Seeing Sage Fukasaku's unkind expression, Jiraiya immediately cowered.

"Tohru-chan, I'll teach you Sage Mode Taijutsu."

"Yes, thank you, Sage Fukasaku!"

ps: The author has specifically learned that Tsunade and Sakura's Creation Rebirth is the effect achieved after the Hundred Healings Mark fully releases Chakra. And the release of the Hundred Healings Mark is controllable.
