Perfecting Ice Release

Yamanaka Tohru channeled the Nature Energy within his body using Chakra. To his surprise, the Nature Energy didn't require deliberate guidance to merge with his Chakra.

As the merged Chakra passed through each part of his body, that part would undergo elemental transformation into ice, and the Nature Energy fused within the Chakra would decrease slightly.

Once Yamanaka Tohru's entire body had transformed into ice, the Nature Energy completely integrated into his ice-elementalized body, allowing him to manipulate it at will.

Afterward, Yamanaka Tohru used Ice Release Water Style while in his ice-elementalized state. It was exactly as Sage Fukasaku had said.

The Nature Energy within Yamanaka Tohru first fluctuated, and then a small portion entered the Water Style jutsu as it was completed.

The Nature Energy in the air was attracted by the Nature Energy within Yamanaka Tohru, surging madly into the Water Style ninjutsu, thereby achieving the effect of Ice Seal Water Style ninjutsu.

The Nature Energy in his body was consumed, and without replenishment from external energy, Yamanaka Tohru's Chakra, due to his body's self-regulation, was supplemented into the depleted Nature Energy.

After a series of experiments, Yamanaka Tohru confirmed that this Nature Energy was the key to his ice-elementalization, and it would fuse with his Chakra upon guidance. It had a special attraction to ordinary Nature Energy but lacked the vitality of ordinary Nature Energy.

Later, Yamanaka Tohru summoned Sage Fukasaku and informed him of his training progress, though he concealed the part about the Nature Energy within his body.

"En-chan, you've clarified Nature Energy, and the next step is to sense it. You felt Nature Energy flowing into your body through the toad oil just now. You need to remember the sensation of Nature Energy so you can feel it even without using the toad oil."

Since there was no concern of Yamanaka Tohru being consumed by Nature Energy, Sage Fukasaku only offered guidance when Yamanaka Tohru had questions about his training. Normally, Sage Fukasaku was elsewhere, teaching Jiraiya.

The original story did not explicitly state when Jiraiya learned Sage Mode, so Yamanaka Tohru did not know when Jiraiya was studying it.

Now, the two of them, being on Mount Myōboku together, had become "classmates."

Jiraiya's first stage of Sage Mode training had been successful. He could enter Sage Mode using toad oil, and he could sense Nature Energy without it. However, he just couldn't find the right method to merge with Nature Energy.

Having understood the essence of Nature Energy, Yamanaka Tohru was very familiar with the Nature Energy he had been using for over three years. In just a few days, Yamanaka Tohru could sense external Nature Energy without toad oil.

Through these few days of training, especially after discovering the Nature Energy within his body, Yamanaka Tohru had been contemplating a hypothesis: could he enter Sage Mode by combining his physical energy, mental energy, and the Nature Energy within his body?

His only concern was that using Sage Mode would consume this Nature Energy. If the Nature Energy within his body was depleted while he was in Sage Mode, how would he replenish it?

Yamanaka Tohru did not intend to experiment until he resolved this issue. He summoned Sage Fukasaku again. Sage Fukasaku was very pleased with Yamanaka Tohru's progress.

Sage Fukasaku did not provide a definitive method for Yamanaka Tohru's next stage of training, merely suggesting that Yamanaka Tohru use ice-elementalization and meditate in that state.

Yamanaka Tohru did not plan to use this method because of the Nature Energy within his body.

Yamanaka Tohru had previously discovered that the Nature Energy within him had a special attraction to external Nature Energy.

While in his ice-elementalized state, Yamanaka Tohru deliberately exposed a portion of this Nature Energy to the outside. As expected, the surrounding Nature Energy surged into Yamanaka Tohru's body like moths to a flame.

In this state, Yamanaka Tohru used the Ice Seal Water Style ninjutsu, and his Chakra was not consumed at all, aside from the release of the Water Style ninjutsu.

The problem that had plagued Yamanaka Tohru for years – the high Chakra consumption of using Ice Release – was finally solved, and Yamanaka Tohru felt immensely relieved.

However, Yamanaka Tohru soon discovered that after using the Nature Energy within his body as a medium to attract external Nature Energy, his elementalization encountered a problem.

Due to the manipulation of a portion of the Nature Energy, there was a palm-sized area on Yamanaka Tohru's body that could not undergo ice-elementalization.

An area the size of a palm that could not undergo elementalization could potentially become Yamanaka Tohru's fatal weakness.

Yamanaka Tohru recalled the Nature Energy within his body, and the external Nature Energy that had been gathered around him began to slowly dissipate.

"Sigh! If only I could gather all this Nature Energy," Yamanaka Tohru muttered to himself.

"Kid, you could try the Yin Seal," Jiraiya's voice suddenly appeared behind Yamanaka Tohru.

"Shit, Uncle Jiraiya, you'll scare people to death by doing that!" Yamanaka Tohru glared at Jiraiya.

"It's not my fault, kid. Your training caused such a commotion. So much Nature Energy suddenly gathered here, and the boss just happened to go home for lunch. I was worried and came to check on you."

Hearing Jiraiya's words, Yamanaka Tohru felt grateful. They had only known each other for a few days, yet Jiraiya cared about him so much.

"Kid, since you're alright, let's not dwell on that. You were just saying you wanted to store Nature Energy?"

Yamanaka Tohru nodded. "That's right. I have a way to gather a large amount of Nature Energy instantly, but I can't store it."

"Then, you could try the Yin Seal that Kushina gave you. Minato told me Kushina inscribed the Yin Seal formula for you. You can completely guide Nature Energy into the Yin Seal formula," Jiraiya said.

"But Uncle Jiraiya, the Yin Seal stores Nature Energy, it can't be used at any time."

"You can try it first. If the Yin Seal can store Nature Energy, I'll help you modify its release. I've seen Tsunade's Hundred Healings Mark."

"Really? Uncle Jiraiya?" Yamanaka Tohru was surprised by the sudden good news.

"Of course. This Sage never goes back on his word. You try storing Nature Energy with the Yin Seal first," Jiraiya waved his hand, signaling Yamanaka Tohru to begin his training.

Yamanaka Tohru did as he had done before. After ice-elementalizing, he gathered a portion of the Nature Energy within his body at the Yin Seal. He opened the Yin Seal's sealing formula, sealed the Nature Energy within his body into the Yin Seal, and the external Nature Energy was attracted, surging madly into the Yin Seal.

Yamanaka Tohru only used a special Nature Energy equivalent to guiding the Ice Seal Water Wave, yet it filled one percent of the Yin Seal's space.

With Yamanaka Tohru's current Chakra, if it recovered normally, it would take about a week to separate 100 masses of special Nature Energy.

This meant it would only take a week to fill the Yin Seal with Nature Energy!

Jiraiya, standing nearby, felt the Nature Energy disappear into the Yin Seal and knew that the Yin Seal could store Nature Energy.

As promised, Jiraiya helped Yamanaka Tohru modify the Yin Seal's release.

The Yin Seal modified by Jiraiya did not possess the various miraculous effects of the Yin Seal used by Tsunade in the original story. However, after being filled with Chakra, it could be released and used at any time. It could also be closed when not in use. But Chakra could only be injected again after the Chakra within the Yin Seal was depleted.
