Daoism believes that the five internal organs correspond to the five elements: the heart belongs to fire, the lungs to metal, the liver to wood, the spleen to earth, and the kidneys to water.
Shinsei often waves his hand, and a virtual figure appears in front of the two of them.
The figure was transparent in the rest of its body, except for its internal organs, which shimmered with five colors: red, white, yellow, black, and blue.
"Teacher, the technique I developed is called the Five Visceral Gods Visualization Method." As Shinsei spoke, he sat cross-legged and explained to Tsunade how to meditate and visualize.
This Visualization Method can regulate the mind and body, increase mental strength, resist negative emotions, and has many benefits for improving physical fitness.
After Shinsei finished explaining, Tsunade suddenly realized that this was not an ordinary technique, but a completely new training system.
In the Shinobi World, the only way to cultivate Chakra has always been through training physical strength; there has always been a lack of a way to cultivate mental power.
This training method, if placed in any ninja village, would probably only be suitable for a Kage to practice.
Tsunade looked at Shinsei with a complicated expression. She felt that she hadn't taught Shinsei much, but Shinsei's reward was so generous.
"Teacher," Shinsei said with a smile, "If you feel bad about it, please return the deducted allowance to me."
"Don't even think about it!" Tsunade shot up. Everything else was negotiable, but she wasn't about to spit out the meat she had already eaten.
After teaching Tsunade, the two withdrew from the mental space, Shinsei felt a weight lifted from his heart.
He felt that although Tsunade thought she hadn't taught him much, that wasn't actually the case.
Tsunade imparted to Shinsei a complete theory of Chakra, advanced Ninjutsu knowledge, Sealing Jutsu, completing the final piece of Shinsei's puzzle on his path to becoming a strongman.
Even the development of Storm Release benefited from Tsunade's guidance.
Without these, it's unknown how long it would have taken Shinsei to reach its current level.
Now I can finally repay my teacher, and next time she tries to "rob" me, I can stand up for myself.
Of course, the so-called returns vary from person to person.
Orochimaru invited Shinsei to be his partner and offered him cloning knowledge and equipment, but Shinsei never considered Orochimaru when considering who to teach.
The two continued on their way, and before long, Shinsei saw a colossal creature, the ruler of the Shikkotsu Forest — the Katsuyu Sage.
This Katsuyu Sage is probably close to a kilometer long and nearly 200 meters tall. Shinsei really can't think of anything that could harm such a behemoth.
"Watch out!" Tsunade grabbed Shinsei. Shinsei smelled a sour odor, like a sour mist formed from overly concentrated acid.
The Katsuyu Sage turned its head, waving its four tentacles. " Tsunade-chan, Shinsei-chan, you're here."
The Katsuyu Sage's voice was no different from the little Katsuyu's, except that its enormous volume was deafening.
"Ah, I'm sorry, it's been a long time since anyone has come to visit." The Katsuyu Sage saw the two stop in their tracks and instantly realized that his acid mist would harm them.
It opened its mouth and inhaled, creating a huge gust of wind.
The strong wind made their clothes rustle, and soon the visible acid mist disappeared completely.
"I'm so sorry, I'll feel hungry if I don't eat."
The Katsuyu Sage created a small Katsuyu, about ten meters tall, which hopped in front of the two. "I'll use it to speak to you."
After saying that, the Katsuyu Sage lowered its head again and nibbled on the leaves on the tree.
" Katsuyu Sage, your body is so big, are these leaves enough to eat?" Shinsei was very curious about how such a huge body needed to be fed.
"No problem, Shinsei," the Katsuyu Sage replied. "I won't eat too fast. Once I finish this side, the other side will have grown back. If it's not enough, I'll use my Sage Art to accelerate its growth." After saying that, the Katsuyu Sage even asked Shinsei, " Shinsei, would you like some leaves? They taste really good."
"No need," Shinsei waved his hands repeatedly.
Using Sage Art to accelerate the growth of food—perhaps this is the most suitable use of Sage Art in the eyes of the Katsuyu Sage.
" Katsuyu Sage, I've come to ask you about Sage Mode," Shinsei said.
The Katsuyu Sage seemed pleased. " Shinsei, you're finally planning to train in Sage Mode? Hmm, you have enough Chakra now, you can start training. Do you want to begin now?"
" Katsuyu Sage, may I ask first, is there any difference between the Natural Energy you absorb here and the Natural Energy absorbed by the Toad of Mount Myōboku?" Shinsei asked.
"They are different, Shinsei. There are many kinds of Natural Energy," the Katsuyu Sage replied.
"If I absorb Natural Energy myself, can you help me expel the excess Natural Energy?" Shinsei did not intend to absorb Natural Energy through Katsuyu, as the Natural Energy he would come into contact with would only be suitable for Katsuyu.
"Oh, Shinsei, you can sense Natural Energy on your own?" The Slug Immortal asked, somewhat surprised.
"Yes, Lady Katsuyu." Shinsei nodded. "I would like to ask you to help me expel Natural Energy when I am in danger, is that alright?"
Tsunade was also surprised. As Jiraiya's friend, she knew that Jiraiya needed Toad Oil to help him train in Sage Mode.
Unfortunately, Tsunade was too young when her grandfather passed away to know how he trained in Sage Mode.
"No problem, I'd also like to see what you look like in Sage Mode, Shinsei. But then you can't cultivate here anymore, as the Natural Energy here has already been assimilated by my true form," said the Katsuyu Sage.
The Katsuyu Sage can assimilate the Natural Energy of this world; it's terrifying!
Fortunately, it was a peaceful creature that only ate leaves in the Shikkotsu Forest. Otherwise, with its size, if it were placed in the human world, perhaps only the resurrected Hashirama Senju and Madara Uchiha could fight it.
Shinsei and Tsunade returned to Konoha and arrived at a clearing in a forest on the outskirts of the Konoha.
Tsunade also wanted to see how Shinsei's Sage Mode differed.
Shinsei bit his finger and slapped it on the ground, and a giant Katsuyu, about thirty meters tall, appeared in the open space.
" Shinsei, this is my special clone. You can focus on your cultivation; I'll help you."
"Thank you, Katsuyu Sage." Shinsei bowed slightly to the Katsuyu. What a wonderful summoning beast! I declare the Shikkotsu Forest, one of the Three Great Sage Lands, number one!
Sitting on the Katsuyu's back, Shinsei crossed his legs and closed his eyes. This time, he was going to actively enter a state of Embryonic Breathing.
Embryonic Breathing is a state that is easily entered when one reaches a deeper level of meditation.
At this time, you will feel all the pores of your body open, and the outside air seems to be connected with your body, as if you don't need to breathe through your mouth and nose, just like a fetus in the womb, so it is called Embryonic Breathing.
Embryonic Breathing is not easy to enter, but it is easy to exit. Once there is a significant disturbance, one will immediately break free from this state. Only those with profound spiritual attainment can cultivate this state into a constant state.
In his previous life Shinsei practiced meditation using more of the methods of the Wenshi School. This school is said to have been passed down from Yin Xi, Laozi chief disciple of Lao Tzu. It emphasizes following the natural way and does not deliberately pursue this state.
After transmigrating into the world of Hokage, Shinsei accidentally entered a state of Embryonic Breathing during his meditation. At that time, he immediately felt the Natural Energy between heaven and earth, and the violent energy left a deep impression on him.
If he hadn't reacted quickly and used his Chakra to push it away, he would probably have been seriously injured. That's why he avoids Embryonic Breathing at all costs.
As time passed, Shinsei gradually emptied himself, and the Qi within his body flowed naturally.
His skin seemed to have been switched on; his body became cool and connected with the outside world, as a surge of violent energy flowed into Shinsei's body.
