When the great elder took the scroll handed by Ren with both hands, his knuckles turned white.
That's no ordinary Ninjutsu reel.
This is something that can rewrite the foundation of Uchiha's future.
He has lived for so many years, and has seen too many geniuses in the clan whose eyes were damaged and their combat power plummeted due to forced overdraft by Sharingan. He has also seen some clan members who are obviously extremely talented, but can only watch themselves stop because their bodies cannot support the consumption of pupil power.
Now, Ren has put the solution in front of everyone.
The first level can be popularized by the entire clan.
It can strengthen the muscles and bones, strengthen the internal organs, and warm and nourish the eyes.
It means so much that this thing fell into the hands of Uchiha.
The Great Elder took a deep breath and said in a deep voice, "Clan Leader Don't worry, I will keep an eye on this matter personally."
"Every household in the clan, every child, every active ninja, and every wounded and retired clan member will be registered."
"I will have someone record clearly who has practiced, to what extent, whether the body has adapted, and whether there are any changes in the eyes."
Tekka immediately said, "I can also bring people from the Battle Hall to cooperate."
Nanami then spoke, "Military Police Force, I will have people train in batches. Patrol cannot be delayed, nor can he delay his cultivation."
Inabi grinned, unable to contain his excitement.
"It's okay now. From now on, Military Police Force guys will have to come back to practice boxing after Tenten Patrol. Anyone who dares to be lazy can be dragged directly to the training ground to practice more."
Many tribesmen in the rear felt feverish after hearing this.
If in the past, many people might not be willing to ask them to practice an additional skill called Taijutsu. After all, Uchiha has always been based on eye skills and Fire Release, and physical training is not the most important part.
But it's different now.
Tiger Leopard Thunderclap can nourish Sharingan and resolve the hidden danger of blindness in Mangekyo.
Based on this alone, no Uchiha dares to despise it.
Ren looked at everyone's reactions and did not let the heat dissipate, but continued to speak.
"Tiger-Leopard Thunderclap Body-Tempering Technique, it's just the first door."
As soon as these words fell, the boiling sound in the shrine suddenly stopped.
Many tribesmen thought they had heard wrongly.
Just the first door?
This kind of physical training method that can solve Mangekyo dead knots is not all?
The great elder suddenly raised his head and his voice changed.
"Master Clan Leader, did you not only create this set of exercises during your retreat and enlightenment?"
Fugaku can't sit still anymore.
He knows the value of Tiger Leopard Thunderclap better than ordinary people.
A set of nine-level physical training methods that can temper the body and warm the eyes, which is enough to make Uchiha's foundation over the next few decades.
But Ren now says that this is only the first door.
Shisui looked at Ren, his tone suppressing shock.
"Master Clan Leader, what else is behind?"
Itachi said nothing, but his eyes were firmly on Ren.
Ren stood in the center of the shrine, his voice was steady, but it was like a heavy hammer hitting everyone's heart.
"The second door is named Great River Qi Refinement Method."
"If Tiger Leopard Thunderclap trains the body, then Great River Qi Refinement Method trains the energy foundation."
"It's not Chakra Refinement Technique for Ninja, nor is it a simple trick to increase the amount of Chakra."
"It is the fundamental cultivation method."
"Even if we compare it with the Chakra Circulation Method, Fire Release Nourishment Method, and Eye-Power Coordinated Breathing Method that were circulated in the Uchiha family in the past, they are still far behind by more than one level."
"To be precise, it's several levels behind."
The shrine became quiet again.
This time, it's not that everyone didn't understand, but they couldn't believe it even more after they understood.
Tiger Leopard Thunderclap has become so powerful that Great River Qi Refinement Method is actually called the fundamental cultivation method by Ren.
Tekka couldn't help but ask, "Master Clan Leader, isn't Chakra Refinement Technique the most basic thing for ninjas? All ninjas rely on it to refine Chakra from physical and mental energy. How can Great River Qi Refinement Method be stronger than it?"
When this question was asked, many tribesmen nodded.
Chakra Refinement Technique is too basic.
From the basics to the Ninja Academy, all children must learn.
But precisely because it is so basic, it almost determines the chassis of a ninja's life.
Chakra has high refining efficiency, large capacity, and strong control. The upper limit will naturally be higher in the future.
If Great River Qi Refinement Method can really far exceed the conventional Chakra Refinement Technique, then its value will never be lower than Tiger Leopard Thunderclap.
Ren did not answer Tekka immediately.
He just raised his right hand.
In the palm of his hand, a wisp of blue energy slowly emerged.
It looks like Chakra, but it is more condensed than ordinary Chakra. It doesn't flow like flames or mist, but like a small river that has been compressed to the extreme.
Fugaku and Sharingan turn on instantly.
Shisui, Itachi, Nanami, the Great Elder, and those Elite Jonin in the front row also turned on Sharingan almost at the same time.
The next moment, their expressions all changed.
"This is not an ordinary Chakra." Fugaku's voice was deep.
Shisui's throat moved slightly, and his tone was heavier than usual. "The density is too high, and the flow is extremely stable, with almost no dissipation."
Itachi stared at the ray of blue energy and whispered, "With the same size, the power of the burst will be stronger than the ordinary Chakra."
Nanami's breathing was obviously a little faster.
"Master Clan Leader, is this what Great River Qi Refinement Method has cultivated?"
Ren nodded.
"Can be called True Essence."
"Ninja refines Chakra, mostly for fighting."
"Refine it when needed, explode it when you cast it, and consume it when you use it up."
"Chakra is like a pool of water. After a battle, the pool is empty."
"And Great River Qi Refinement Method is different."
"It does not treat energy as a one-time consumable, but builds the energy in the body into a river."
"The wider, deeper, and longer the river, the more stable and lasting the energy is, and the harder it is to dry up."
"When you have cultivated to a high level, the True Essence in your body will surge endlessly. Even if you fight for a long time, you can continue to recover, nourish and replenish it."
Tekka heard this and his mouth opened slightly.
"Isn't this just... the more you fight, the better you can hold on?"
Ren glanced at him.
"More than just being able to hold on."
"After the same Chakra is tempered into True Essence by Great River Qi Refinement Method, the power will be stronger, the control will be finer, and the consumption will be lower."
"Fire Release will be more condensed, Lightning Release will be more penetrating, Genjutsu Chakra will be more stable, and the energy flow between everyone will be smoother when Temple Formation."
"What this means, I don't need to say more."
No need for him to say it, everyone understands.
What Temple Formation is most afraid of is the different strengths, different flow rates, and uneven consumption of Chakra among different tribesmen.
If everyone practices Great River Qi Refinement Method and makes their own Chakra more stable, then the burden on the array will be greatly reduced and the explosive power will be stronger.
A Battle Hall Jonin couldn't help but whisper, "If Land of Lightning were on the battlefield and we had this technique, Kumogakure the front line wouldn't have been able to last that long."
The other person next to him nodded, his voice trembling.
"We will not win a little bit, but we will win more thoroughly."
The great elder could no longer sit still.
He took half a step forward while holding on to his crutch, staring intently at the wisp of True Essence in the palm of Ren.
"Master Clan Leader, if you only temper Chakra, it will be amazing enough."
"But you just said that it is the fundamental cultivation method."
"Its upper limit should be more than that, right?"
