I, Uchiha Yu, am solely focused on cultivating immortality

Chapter 39 Are you a demon?

It was getting late, so Uchiha Yu personally escorted Uchiha Shisui home to prevent any unforeseen circumstances from arising.

On the way, he reminded Shisui, "You can tell the clan leader and a few elders about the Cat Sage's cultivation methods, but don't tell anyone else. Let the clan leader and the others make the judgment."

"Yes."

"In addition, this training method is extremely effective, but it cannot completely replace physical training. The necessary training cannot be stopped. Only by advancing in both directions can we achieve the greatest growth."

"Oh, I see. I understand now. I will continue with my physical training."

The two talked about cultivation and soon arrived at Shisui's house. It was a large three-courtyard mansion, with ninjas even acting as gatekeepers at the entrance.

"Wow, your house is really nice," Uchiha Yu joked with a smile. "Then don't be late tomorrow."

Uchiha Shisui suddenly smiled happily. Uchiha Yu was indeed different from others; upon seeing his own front door, he simply made a casual remark.

Unlike the friends I made before, who would immediately become timid and withdrawn once they learned about my situation, making it impossible to remain friends.

With extensive knowledge, rich experience, gentle personality, unparalleled popularity, and formidable strength, Uchiha Yu truly deserves to be the only contractor chosen by the only Cat Sage. He is indeed an extraordinary and outstanding individual.

"Brother Yu!"

"Hmm, what's wrong?"

"Thank you so much for your hospitality and for your guidance. I have learned so much today."

"We are both of Uchiha blood. Since we are destined to meet, we are family."

"We're family, so let's not speak like strangers."

"Hey!! I won't be late tomorrow!"

"Okay, see you tomorrow."

……

Time always flies when everything is going smoothly.

Two days passed in the blink of an eye.

Over the next two days, Rin and Shinichi completed their water-walking training. In addition to carrying weights while walking on water, Uchiha Yu began to teach them some combat techniques and correct some dangerous unnecessary movements.

As for real battlefield survival skills, they certainly won't be taught, since what Uchiha Yu already knows isn't suitable for the large-scale wars to come.

Although I have seen a large number of records in the archives, they are mainly based on techniques from the Warring States period, which may not be suitable for the current mode of warfare.

If we teach this unverified stuff to three genin, wouldn't that be a disaster?

"thump"

"I @%￥##@#@@"

Amidst Obito Uchiha's defeated wailing, Yuu Uchiha helplessly turned to look at the river: "How many times has this happened?"

Shisui covered her mouth, barely suppressing the urge to burst out laughing: "This is the 14th time."

"We started at 8:30, and it's not even 9:00 yet..."

"That Obito... he's not just hard to subdue like a monkey, he's sent by the monkey to torment me!"

Uchiha Yu suddenly stood up, flashed to the river surface, scooped Obito out of the water, and before Obito could let out his characteristic silly grin, threw the guy onto the shore.

Uchiha Yu's actions caused Obito to scream in agony: "Ah—, I'll succeed next time, I don't want to…"

"No, what you want is weight training!"

He rudely interrupted Obito's screams, put the forty-kilogram weights on him, and then said in a caring whisper, "If you dare to disobey, I'll have to punish the whole squad."

"Obito, you wouldn't want Rin to run with weights on you, would you? Her body is so frail..."

"Are you... are you a demon?"

"No, no, no, I'm just choosing to make you suffer a little more between driving you crazy and exhausting you to the point of madness."

Obito Uchiha shut his mouth, his eyes blazing with anger, but he dared not utter a curse, fearing that Yuu Uchiha would use his mistake as an excuse to punish Rin again.

Seeing Obito's angry but speechless expression, Uchiha Yu felt much better: "Go and surround the Hidden Leaf Village with its walls!"

Watching Obito storm off the training field, Shisui couldn't help but worry: "Obito-nii seems really angry. Won't he get hurt running like that?"

Uchiha Yu glanced at it and dismissed it: "Don't worry, this speed is still within his tolerance range."

"what?"

"Shisui, you can't underestimate Obito. In some ways, his talent is even greater than yours."

"It's just that his mind is too active, preventing him from showcasing his talent."

"Really?" Shisui was extremely surprised and couldn't help but look at Obito.

Even after Obito Uchiha disappeared into the forest, he still couldn't figure out where that stumbling figure's talent lay.

"Stop looking at it. Practice the movements I taught you again. Let me see if there's anything that needs adjusting."

"Yes."

"Focus on this and stop thinking about Obito. When he comes back, anyone who's paying attention will be able to tell at a glance."

"yes!!"

It has to be said that Uchiha Shisui's talent is truly visible to the naked eye. This time, his movements are more skilled and fluid than the last time, and his progress is too obvious.

Uchiha Yu couldn't help but praise, "Although it wasn't a perfect performance, I don't think there's anything that needs adjusting now that you're in the same boat."

"Don't get too excited yet. I still need to see how well you perform in chakra extraction and retention."

"yes!"

This is what makes Uchiha Yu's attitude towards chakra completely different from other ninjas.

Normal ninjas draw chakra from their cells as needed, only extracting it when they are about to use it, then mixing it with spiritual energy before using it in battle.

However, Uchiha Yu believed that this was too slow, and that the sudden and intense extraction was very bad for the body and could easily cause problems and damage.

Even ninjas who frequently fight on the front lines, despite taking good care of themselves, are still prone to injuries and fatigue, such as the Tsuchikage Onoki.

The ninjas who stayed safely in the back could live healthy lives even if they were always smoking, like the Third Hokage.

Uchiha Yu believed that chakra should be extracted in an orderly manner, stored for a long time, maintained in peacetime, and unleashed in battle. This was the complete system. Relying solely on unleashing chakra in battle was a short-sighted and evil path.

Well, the ninja world is dominated by neon-style culture, so it's not surprising that they're so focused on quick success and instant benefits.

Moreover, the name of the profession of ninja is very convincing. A ninja is someone who can endure everything. To use chakra, one must first endure the unavoidable pain in the body when chakra is circulating.

If trained from a young age, a ninja's body will adapt over time, the pain will decrease, and they will even get used to the pain, feeling uncomfortable instead.

But Uchiha Yu just couldn't accept it, even though this pain wasn't as painful as the Sichuan cuisine's impact on his anus.

Why did Uchiha Yu risk absorbing natural energy even though he knew it was dangerous?

Firstly, in the worldview of my previous life, cultivating immortality was the most prestigious and extraordinary path to transcendence. If you didn't try it when you had the chance, could you still be considered a member of the Yanhuang race?

However, the reason they were able to persevere until they discovered that fire was harmless was because a small amount of natural energy could alleviate the pain, the kind of lingering pain that spread throughout the body, like the pain of rheumatoid arthritis.

Uchiha Yuu instructed Shisui on techniques for adjusting chakra, all of which are key to eliminating pain and the harmful side effects of chakra. It also allows chakra to be retained in the body long-term, maximizing the body's adaptation to chakra and enhancing chakra output power and controllability.

In the traditional understanding of the ninja world, chakra is a supernatural power that can kill, and even medical ninjutsu requires sacrificing lifespan to heal injuries.

However, Uchiha Yu believes that this is not absolute.

Because Kaguya Otsutsuki, the progenitor of chakra, is truly immortal.
