“A few centuries ago,
The shinobi world is engulfed in war and chaos. There is no proper state line. The various clans fought each other, either for territory or for resources.
The Senju Clan was one of the most powerful clans. The Senju clan enlisted in the battle against the Uchiha clan, another powerful clan.
During that War period, the leader of the Senju clan had five descendants. His eldest son was talented in battle.
Kenshiro's youngest son is quite stupid. He couldn't even master any basic ninjutsu. In the battle against the Uchiha, the three brothers fell into the hands of the genius of the Uchiha clan, Tenma Uchiha.
Unable to bear the loss of his brothers and to overcome his helplessness, Kenshiro leaves the Senju clan on a journey to achieve power.
During this journey, Kenshiro learns Fuinjutsu. During this time, he helped me seal the creature and help the Shikkotsu Forest."
Katsuyu walked out of the cave and led Izuna. After walking for a while, they arrived in front of a large temple. Katsuyu and Izuna enter the temple.
In the center of the temple, Izuna saw a giant statue of a man. The man had long pointy hair and giant scrolls tied around his back. He has two shoulder protectors with the Vajra symbol in one of them and the spiral symbol in the other. His hands were clenched, and he was in a fighting position.
"He is Kenshiro Uzumaki! Kenshiro Senju, to be exact. In his honor, a call from the Shikkotsu forest built a temple and erected his statue."
Izuna looked closely at the statue and saw strange marks all over the body of the Statue. The signs were very similar to the Strength of the Hundred Seals. He turned towards Katsuyu and questioned him,
"Isn't that the Power of a Hundred Seals? That's Tsunade's technique, right?"
Katsuyu nodded at him and replied,
"This is indeed similar to the Hundred Seals Power as Tsunade obtained her technique from this jutsu. Tsunade's Rebirth Creation Technique is incomplete.
Kenshiro-sama created this technique to use together with Sage Mode. Mito-sama modifies the technique to use the Normal Chakra instead of the Sage chakra and Tsunade-sama further enhances the technique.
But now his technique has side effects. The Original Technique created by Kenshiro-sama has strict requirements but has no side effects."
"Oh! There's such a thing. Then why don't you help Tsunade-san to learn this original technique." Izuna questioned Katsuyu.
"I tried to convince Tsunade-san to learn this technique. But it takes a lot of time to learn, and Tsunade-san took part in the Second Shinobi War during her youth, and then the loss of her loved ones caused trauma to her. So, he ignored this technique." Katsuyu sighed.
"I will convince Tsunade to learn this technique. He will obey my request. You can train Tsunade in this technique." Izuna convinces Katsuyu and examines the temple.
There were various seal scrolls placed inside the temple. Izuna took one of the scrolls and read it.
"Oh! This scroll had many sealing techniques written on it. This seal far surpassed the level of Grandmaster."
"Yuzuna-kun! Kenshiro-sama created this seal. He was famous as the 'Sage of Sealing' throughout the Shinobi World. He was a very powerful Shinobi, but unfortunately he lived a short life."
Katsuyu sighed and reminisced about his past. Izuna's interest and she questioned Katsuyu.
"Miss Katsuyu, how did she die? He's a powerful Shinobi, right? Who could kill him?"
Katsuyu looked at Izuna and hesitated for a moment before she revealed the fact, though,
That was your ancestor, Tenma Uchiha. Tenma Uchiha awakens the Mangekyo Sharingan's powers and fights in a battle against Kenshiro-sama. Their battle is fierce, Tenma Uchiha has the power of Susanoo whereas Kenshiro-sama has the ascetic Mode and its various sealing techniques.
Their battle lasted for two days and two nights. Kenshiro-sama ended the life of Tenma Uchiha. Unfortunately, Kenshiro-sama succumbed to his injuries as a result of that battle."
'It looks like Kenshiro Senju and Tenma Uchiha are past incarnations of Asura and Indra Otsutsuki. It is their destiny to clash in each incarnation. With the Black Zetsu behind the scenes, it was impossible to avoid a battle.'
Izuna checked the scrolls and the remaining comments, though,
"Kenshiro Uzumaki has a very high talent for Sealing. To gain fame as the 'Sage of Sealing' and clash with Susanoo with Fuinjutsu and Sage Mode alone.
He turned towards Katsuyu and asked her,
"Miss Katsuyu, can you help me in training the ascetic Mode? I want to master Senjutsu and become a Sage."
"Well! I will help you learn Sage Mode, but you must be compatible with Sage energy to master it. Otherwise, you will turn into stone because of the powerful energy of Nature."
'Conformity! I was born with it. I just need to log in and learn Sage Mode. Later on, I will look for a way to get 'Six Paths Sage Mode.'
Maybe I should call the frog and ask the old frog about Hagoromo Otsutsuki. He must have some knowledge of the 'Six Path ascetic Mode'.
Izuna made her plan.
"Miss Katsuyu, do you have some kind of help that helps speed up the learning process?" He remembered about the Toad oil from Mount Myoboku.
"Yes! This is the oil of snail secretion. If you apply it to your body, you can absorb the energy of Nature much faster." Katsuyu brought her to the pool filled with a white sticky liquid.
"Ughh! It's..."
Izuna looked at the slimy liquid and complained.
"I'm not going to apply it to my body. I'll learn Sage Mode through Normal means." Izuna complained.
"That was your choice, Izuna-kun."
Katsuyu crept towards the giant tree in the middle of the forest.
"Yuzuna-kun. The first and foremost thing required to master the Ascetic Mode was a calm mind. If your mind is calm, then only you can concentrate on the energy of Nature.
Natural energy is everywhere. Each breath contains the energy of Nature. The Chakra system of the body absorbs the energy of Nature and converts it into Chakra to replenish the Chakra. In this way the Chakra System acts as a converter.
But in this case, we lose the energy potential of Nature. Chakras acquire the nature of the element and thus lose their versatility. Natural energy has no element of Nature which makes it more flexible and powerful.
There is a catch here. Having no basic nature, it is very difficult to feel it. And the excessive energy intake of Nature will turn a person to stone, because the energy of Nature has the will of the planet.
Now, do you have any more questions? If not, we will start with meditation. Remove all exaggerated thoughts from your mind and focus on feeling the energy of Nature."
Katsuyu instructed Izuna and helped her concentrate.
"Uhhhh! Miss Katsuyu. I used to meditate to calm my nerves. I can easily enter the condition of 'Mind Zero'. Can we proceed to the next stage of training?"
"... If so let's move on to sensing the energy of Nature." Katsuyu looked at Izuna in disbelief. His Optical Tentacles were shaking in panic.
"Izuna-kun, you should enter into a meditative state and try to feel the energy of Nature around you. You're a sensor-type ninja, right? It will be easier for you to feel the energy of Nature. Just concentrate and feel the energy of Nature. .
This gigantic tree released a huge amount of Natural energy. That's part of the reason I brought you under this tree. You will be able to sense the energy of Nature easily here.
But if you are having difficulty in sensing the energy of Nature, then you can always apply Snail oil and passively absorb the energy of Nature and feel the energy of Nature."
Katsuyu pointed towards the snail oil pool.
"Anything! But it's. I'll figure out a way to feel the energy of Nature myself." Izuna crossed her arms in denial.
"Well! If you say so. I'll stay here and monitor your progress. I will prevent you from turning into stone if you absorb the excessive energy of Nature." Katsuyu slid onto a nearby rock and leaned against it.
Izuna closed her eyes and entered a mediating state.
'Let me try to feel the energy of Nature with my body first.'
