From the night of genocide, marching towards the strongest.

Secondly, this is an advantage. In the future, he can imitate the thermal motion of molecules and incorporate the principle of intermolecular motion when releasing fire-style chakra from his mouth, so that when he releases fire-style ninjutsu such as the Great Fireball Technique from his mouth, the temperature will be higher and the speed will be faster!

However, one must also be mindful of the degree of intensity to avoid excessive speed within the mouth's chakra, which could lead to instability and burns.

Solving one problem led to two more, but Sasuke doesn't seem to care at all.

The wiser a person is, the more problems they will discover, the more aware they will be of their own shortcomings, and the more humble they will become.

Only a frog at the bottom of a well would think that the opening of the well is the whole sky.

Sasuke quietly closed his eyes. As long as he could find the problem and confirm that the path was correct, then everything would be fine.

As is customary, I usually write down a summary of what I learned that day on paper, go through it in my mind, and then destroy it.

.........

Night had fallen, and Sasuke had finished his day's training and entered his room. However, instead of resting immediately, he lay face down on a mat on the tatami mat, elbows bent, hands on the ground beside his waist, legs straight, insteps pressed to the ground. He inhaled, straightened his elbows, lifted his body off the ground, hands on the ground, insteps pressed to the ground. He exhaled, looked up at the ceiling.

At the same time, exhaling with each forward bend and inhaling with maximum force when contracting the body seems like a very strange movement.

Yoga!

The movements Sasuke is making now are naturally derived from yoga in his previous life.

In his previous life, he was a fitness enthusiast. Like most men, he chose weightlifting, while his girlfriend chose yoga.

In his previous life, he had never practiced yoga, but through their long-term cohabitation and exposure to it, he gradually learned to practice.

He is very familiar with yoga as a fitness exercise, and he has memorized the key points and proper forms of the movements.

Two months ago, after deciding on his spiritual practice plan, he began to study yoga seriously, and he would practice yoga for an hour every night before going to bed.

Yoga is a fitness exercise that can improve physical flexibility, promote blood circulation, and eliminate toxins from the body. When practicing yoga, you can also enjoy a massage-like effect. For him, who is almost in a grueling training regimen every day, it is a very good way to relax.

In addition to physical benefits, yoga can also soothe the mind and spirit, achieving a state of concentration and tranquility.

The meditation practice that Sasuke previously set out as a method to increase spiritual energy refers to yoga and yogic meditation.

Yoga was one of the six major philosophical schools in ancient times. The practice is divided into seven stages: root chakra, sacral chakra, navel chakra, heart chakra, throat chakra, third eye chakra, and crown chakra. The highest stage of practice is the state of "union with Brahman".

Legend has it that before attaining enlightenment, Buddha Shakyamuni was a master of yoga asceticism, and later, many aspects of yoga meditation were incorporated into Buddhist meditation.

The yoga that Sasuke learned was not the yoga of ancient religions, but a kind of fitness and mind-cultivating exercise found in yoga studios that can be found everywhere on the streets of modern times.

The concept of chakra in Naruto originates from the energy centers in yoga, which refer to the energy centers distributed throughout the body, especially those arranged along the central axis of the body from the tailbone to the top of the head, namely the three channels and seven chakras!

He wasn't sure if there was any special relationship between his past life's yoga and the chakra of this world, but after two months of training, Sasuke could clearly feel that his spirit was getting better and better, and the speed at which he could refine and circulate chakra had also improved.

Since it can increase strength and relax the mind and body, it achieves two goals at once.

Sasuke persevered.

Chapter 13 Chakra Metal Weapons

As evening fell, Sasuke, having finished another day at the Ninja Academy, slowly walked into the deserted Uchiha clan compound.

As soon as Sasuke entered the clan's territory, he felt a gaze coming from the rooftop to the east. Following the gaze, he saw a cat dressed in blue, carrying a small scroll on its back, with pointed ears, raccoon-like fur, and the character "忍" (ninja) written on its forehead.

"Young Master Sasuke!"

Upon seeing that Sasuke had discovered it, the cat surprisingly spoke in human language. With a few light leaps and quick movements, it appeared beside Sasuke and spoke.

"Young Master Sasuke, your custom-made chakra weapon is ready."

"Okay! Thank you for your help, Tian Huo."

Sasuke nodded, took the scroll off the ninja cat's back, and handed it a bottle of catnip drink.

The cat had barely taken the drink when it eagerly opened it and sniffed it, displaying an expression of pure enjoyment reminiscent of a cat inhaling mint.

The Ninja Cat Clan is the Uchiha Clan's intelligence source. The Ninja Cats are raised by Granny Cat, who makes tools specifically for cats. Their favorite drink is catnip beverage.

They lived in a ruined city dozens of kilometers away from Konoha, in a place called the Empty Zone.

The two sides have been cooperating for decades. In addition to serving as an intelligence source for the Uchiha, Granny Cat and the Ninja Cat Clan are also responsible for creating custom ninja tools and weapons on behalf of the Uchiha.

Sasuke's previous request to purchase a katana made of metal with full chakra conductivity was made through a request he made to Granny Cat via Ninja Cat.

After all, given Sasuke's current status and strength, even if he had the money, it would be very difficult for him to obtain a chakra metal weapon in Konoha. Moreover, there are not many people Sasuke can trust and rely on right now, and Granny Cat is one of the very few.

However, even though he entrusted the task to Granny Cat, chakra metal was not easy to find, after all, it was a precious item. More than two months had passed since the task was entrusted, and he only obtained this weapon today.

Sasuke opened the storage scroll, and after a puff of smoke, a katana and a small knife the size of a dagger appeared in his hand.

The samurai sword is entirely white with a gleaming blade. It is a katana with a blade length of about 80 cm. The blade is extremely long, thin, and slender. A red and white protective cord is tied to the hilt.

"A fine knife!"

Sasuke pondered for a moment, then sheathed his katana and asked:

Does this knife have a name?

Upon hearing this, Tianhu reluctantly turned his gaze away from the catnip drink and replied, "No, young master Sasuke, Granny Cat said that you are the master of these two weapons, and you can name them yourself, meow!"

"Ok."

Sasuke nodded, then took out another short dagger and examined it closely.

The saying goes, "An inch longer, an inch stronger; an inch shorter, an inch more dangerous."

He had considered his profession and fighting style beforehand, and he knew that he would inevitably have to fight close to the enemy in the future. In addition to his katana, he also commissioned Granny Cat to forge a short sword.

Besides its use in close combat, the short sword can also be used in conjunction with his throwing techniques, functioning as a kunai shuriken.

Of course, after his previous conversation with Sakura, Sasuke now has other plans regarding this short sword.

"By the way, Tian Huo, there's something else I'd like to ask Granny Cat for help with."

"Young Master Sasuke, please speak, meow!"

"Could you please help me collect some information about Lightning Release techniques, Granny Cat..."

At this point, Sasuke hesitated for a moment before continuing, "I want all five types of ninjutsu, the level doesn't matter, but of course the higher the better."

Although he already possesses the Uchiha-style Fire Release ninjutsu and Uchiha Shisui's Fire Release swordsmanship, knowing that the original owner of this body had extremely high lightning-style talent, he would not give up such a powerful talent for nothing. For now, he will definitely focus on fire-style, but in the future, he will also develop both in parallel.

As for the other three systems, he only came for reference and has no intention of cultivating them for the time being.

"Is young master Sasuke going to collect the scrolls of the five elemental ninjutsu?"

Tianhu licked her paws, pretending to be deep in thought. After a moment, she said, "I heard Granny Cat mention before that she has some scrolls about the five elemental ninjutsu at home, but most of them are only D or C rank. Ranks above C will be a bit difficult. Meow!"

"That's okay, even the basics are fine."

Sasuke nodded and said in a deep voice.

"Okay!" Tian Huo nodded his little head.

"Young Master Sasuke, if there's nothing else, I'll be going now, meow!"

"Ok!"

As soon as he finished speaking, Tian Huo turned into a wisp of smoke and disappeared.

Sasuke, after familiarizing himself with the two new weapons, continued his daily training.

..........

The next day, at the Uchiha clan's territory.

After having breakfast and undergoing his usual physical training, Sasuke took the dagger he had just acquired and headed to the back mountain of Konoha Village.

Today is the weekend, and there's no school. Sasuke doesn't plan to undergo his usual day of grueling training, but instead intends to embark on a new training journey.

Walking along the path leading to the back of the mountain, he noticed that he had grown significantly taller than he had two months ago.

Regular sleep schedule and a variety of highly nutritious meals

More than two months of persistent physical training and yoga stretching and flexibility exercises have made him appear taller and stronger than his peers.

"That's senior Sasuke, a genius from the grade above us at the Ninja Academy."

A soft, melodious voice drifted over, and Sasuke looked in the direction of the voice. He saw two girls, two or three years younger than him, whispering to each other and glancing at him from time to time.

When Sasuke looked over, the two girls weren't shy at all. Instead, they waved and giggled softly, covering their mouths.

"I'm considered a celebrity at the ninja academy, you know..."

For more than a week since starting school, Sasuke has often run into and heard some of his classmates talking about him. The boys naturally discuss his talent and strength, and their tone is full of envy, jealousy and resentment.

Sasuke could tell at a glance that those bold young girls were only after his beauty.

He chuckled to himself, and before he knew it, Sasuke had reached the foot of the back mountain. As soon as he arrived, he noticed at least five or six pairs of eyes watching him from the shadows.

Sasuke remained calm and walked slowly into the back mountain, while those gazes only stared at him for a dozen seconds before disappearing.

The back mountain of Konoha is also part of the village's territory, and villagers and ninjas are not prohibited from entering it. In fact, some ninjas' residences are located on the back mountain, such as Might Guy and his son in the original work.

However, because the back mountain has many forests and hills, it is very well hidden. In order to prevent unidentified people from sneaking in, and also to prevent some villagers from being attacked by wild animals that accidentally wander into this area.

Therefore, several teams of ANBU ninja members patrol this area day and night.

Chapter 14 Hello, I am Kurama Yakumo

The back mountain was covered with a lot of vegetation and wild grass, and various towering trees. Sasuke stopped at a small hill a few meters high. At the foot of the hill were stones the size of a normal person's head.

Sasuke drew his short sword, twirled it a few times in his hand, and after getting a feel for it, picked out one of the stones.

What Sasuke needs to do now is to carve!

To be precise, it's sculpted using chakra!

After a conversation with Sakura, Sasuke picked up the carving technique he had abandoned many years ago in his previous life.

In his previous life, he did not come from a family of sculptors. His father was just an ordinary stonemason in the countryside who made a living by accepting commissions such as tombstones, engravings, and patterns.

His father was an illiterate, rough man. Even when he accepted commissions to carve inscriptions, he would simply carve the characters onto the paper provided by the client, as if drawing a picture. The resulting inscriptions were varied in depth and lively in appearance.

Although he was illiterate, his father was the most popular and busiest stonemason in that town, and demand far exceeded supply. It was only after various sand carving machines appeared that his career gradually declined.

Just like the butcher Ding carving up an ox, his father in his previous life could be said to have devoted his whole life to carving, even though he was not from a family of carvers, nor from a famous family, and did not understand any art schools.

But he could use even a simple stone with ease and skill. In his eyes at the time, his father's works were many times more beautiful than those so-called masterpieces.

Although my father possessed this skill, he had no intention of letting him inherit it. In the eyes of people of my father's generation, studying was the most promising and prestigious path.
