The door to the small room next to the office opened, and Tsunade stretched and walked out.
She rubbed her sleepy eyes and said, "Even after coming to this world, I still don't like them. What brings you here?"
Shinsei replied, " Sasuke needs to learn Sage Mode. Sensei, you should be almost ready to learn it too. So let's practice together this time."
The two Tsunade exchanged glances. The younger Tsunade said, "You go ahead, I'll sleep a little longer."
The Hokage version of Tsunade didn't object and nodded in agreement.
Shinsei has discovered that there must be a similar method of memory assimilation between the two teachers. As long as one of the masters learns a certain Ninjutsu, Tsunade can basically learn it very quickly as well.
The Yin Seal on their foreheads look the same as before, but their internal structure is completely different; they have likely been upgraded to Yin-Yang Seal. It seems they are preparing for Sage Mode in advance.
The three of them arrived at the outskirts of Konoha. The scenery here was beautiful, with towering trees and a small river meandering into the distance.
Shinsei bit his finger and slapped it on the ground. A Katsuyu about ten meters tall appeared in the arena.
" Lady Tsunade, Lord Shinsei, Lord Sasuke." The Katsuyu appeared very happy as soon as it came out, waving its antennae and cheerfully greeting everyone.
" Lady Katsuyu, we need to practice Sage Mode. Could you please absorb the Natural Energy from Master and Sasuke's bodies in a moment?"
"No problem, leave it to me!" the Katsuyu agreed.
The biggest difference between Shinsei's Sage Mode and the Sage Mode of the Three Great Sage Lands lies in the difference in Natural Energy.
Before practicing Sage Mode, people at Mount Myōboku need to have Toad Oil applied to them to help them sense Natural Energy.
To reach Ryūchi Cave, one needs to be bitten by the White Snake Sage; if one doesn't die, one can naturally sense Natural Energy.
Shikkotsu Forest also employs similar methods, applying a liquid secreted by Great Sage Katsuyu to those practicing Sage Mode.
All of the above methods are designed to help those practicing Sage Mode sense Natural Energy. The advantage is that it helps people quickly get started, but the disadvantage is that the Natural Energy sensed from then on becomes fixed, and the Sage Mode that is truly suitable for humans becomes incompatible with it.
Shinsei cannot secrete any fluids to help others sense Natural Energy, but he can channel the Natural Energy he absorbs into others' bodies.
Tsunade and Sasuke sat cross-legged in front. Shinsei sat behind them, placing his hands on their shoulders, closing his eyes and clearing his mind.
As he entered a deeper state of tranquility, a vast amount of Natural Energy surged into Shinsei's body from all parts of his body.
Shinsei opened his eyes, Chakra within him rapidly channeled Natural Energy through his arms into both of their bodies.
Tsunade and Sasuke felt a surge of violent energy flowing into their bodies from their shoulders, and they quickly enveloped it with their physical and mental energy.
Before the two could synthesize it into Senjutsu Chakra, a powerful suction force emanated from the Katsuyu beneath them, drawing Natural Energy out of its body.
A small Katsuyu split off from the body of the large Katsuyu and turned into a puddle of clear water.
Tsunade frowned; the Natural Energy just now was far too violent, and her body simply couldn't react in time.
A sharp pain shot through her body. Tsunade gathered her Chakra to repair the damaged cells.
A gentle breeze blew by, and a few strands of golden hair fell out from Tsunade's hair.
Tsunade raised her hand and ran it through her hair, revealing even more stray hairs on her hand.
"No wonder Shinsei went bald after practicing Sage Mode. The damage this Natural Energy inflicts on the body is truly extraordinary."
" Lord Sasuke, let me help you heal." A small Katsuyu split off from the Katsuyu beneath him and crawled onto Sasuke's shoulder, repairing the damaged cells in his body.
Sasuke endured the excruciating pain, looking at the much thinner hair on his arms, but he didn't care. As long as he could increase his strength and kill that man, even becoming bald was a trivial matter to him.
The most important step in cultivating the Star Sage Mode is to perceive the Natural Energy that Shinsei perceives. This way, when they can absorb Natural Energy on their own in the future, the Natural Energy they absorb will be the same as that that Shinsei perceives.
The remaining effort involves meditating and entering a state of tranquility, consciously seeking out the presence of Natural Energy. This stage is also highly dependent on talent; some will learn it, others will never.
If learning the Sage Mode of the Three Great Sage Lands can summon sages to help absorb Natural Energy, it's like Jiraiya summoning Sage Fukasaku and Sage Shima.
Shinsei wouldn't do such troublesome things; he's not Toad from Mount Myōboku with so much free time.
Once the two had recovered, Shinsei once again infused them with Natural Energy.
The two felt the violent Natural Energy surge into their bodies from their shoulders once again, and they quickly combined it with their physical and mental energy.
Having had experience before, Tsunade accurately grasped the ratio of physical and mental energy, enveloping the Natural Energy within her body. Before her Senjutsu Chakra could even form, a tremendous suction force came from beneath her.
The Natural Energy was sucked away by the Katsuyu beneath him.
Tsunade patted the Katsuyu's bouncy body. " Katsuyu, I'm almost there! You can absorb the Natural Energy a little later."
"But Lady Tsunade, your body won't be able to take it!" The Katsuyu refused Tsunade's request.
Feeling the stinging pain all over her body, Tsunade saw that all the body hair on her body had fallen out, and strands of her golden hair drifted down in the breeze.
She quickly grabbed a handful of hair from her head, and more stray hairs appeared in her palm.
Seeing Shinsei suppressing his laughter, Tsunade was furious.
"What are you looking at! Turn your head away!"
Shinsei quickly turned his body away, refusing to look at the bald patches on Tsunade.
Tsunade down on Sasuke's shoulders, holding his body still. She took a deep breath and blew hard on Sasuke's head.
Tsunade blew countless stray black hairs everywhere with a single breath.
Sasuke's head was now covered with even patches of baldness, and he no longer had the handsome look he once had.
Shinsei couldn't hold back any longer and burst into laughter, clutching his stomach.
Tsunade frowned, her hands Hand Seals. The seal between her brows transformed into black runes, spreading throughout her body.
Ninja Art: Strength of a Hundred Technique!
Stimulated by a large amount of Chakra, thick golden hair regrowed from Tsunade.
Tsunade, stroked her newly grown hair with satisfaction, and then pointed at Sasuke's head and laughed heartily without any restraint.
