Worthy of a protagonist-his potential was immense

Sasuke noticed Lin Yan staring at him, looking completely bewildered.

"Elder brother..."

He tilted his little head, looking at Itachi with a hint of anticipation.

Having witnessed firsthand the power of the Six Powers, a formidable physical technique that even his own brother was nearly defeated by.

So even at such a young age, Sasuke was somewhat looking forward to it; after all, it's always good to have more skills.

Itachi was, of course, more tempted.

What's most important to deal with ninjas? Intelligence.

The more you know about your enemy, the greater your chances of winning.

Although Itachi had already learned the Six Powers through the Sharingan's copying ability.

However, he believes he can learn more about the techniques and other aspects of the Six Powers.

Another important reason is that Lin Yan's physical skills are so powerful, and the "Tekkai" technique in the Six Powers can make a person's body even stronger than steel.

The physical weakness of ninjas has always been their disadvantage.

Itachi had come to this realization deeply ever since he became a ninja and began carrying out missions.

If one could control the "Tekkai," the benefits it would bring would be unimaginable.

Of course, besides himself, he also needed to consider his younger brother Sasuke.

Lin Yan's Six Powers are comprehensive and multi-dimensional, encompassing speed, power, and defense.

If Sasuke could also learn the Six Powers, then I, as his older brother, would feel very relieved and at ease.

After a brief moment of thought, Itachi nodded. "That's no problem."

"Alright, let's begin now."

Lin Yan nodded and looked at Naruto, who was staring intently at Itachi.

Itachi turned his head and looked at Naruto.

"I'll explain the basic concepts of Chakra to you now. The specific methods of refining it will be covered after you're familiar with the concepts..."

Before Itachi could finish speaking, Naruto blurted out, "I know what Chakra is!"

"You know?"

Itachi looked somewhat surprised, a flicker of doubt crossing his eyes.

However, he didn't ask any further questions, but instead turned around and looked at Sasuke.

"Sasuke, since that's the case, then I'll also teach you the method of Chakra refinement here."

"Really? Brother! That's wonderful!"

Sasuke was very excited.

He had been begging Itachi to teach him the method of Chakra extraction.

However, Itachi always refused, using the excuse that it wasn't the right time yet.

Now the opportunity has finally arrived.

Seeing his excited younger brother, Itachi turned to Lin Yan and asked, "Do you want to study too?"

"I'm not sure if I can learn it, but if I can, I don't mind learning another skill."

Lin Yan answered.

Itachi nodded without saying anything more and began explaining the concept of Chakra to Lin Yan, Sasuke, and Naruto.

After briefly introducing the concept, he immediately began explaining how to refine Chakra.

"To refine Chakra, we need to first fuse the spiritual energy and physical energy within our bodies in a 1:1 ratio."

"But before you actually try to merge these two energies, you must feel their presence within your body."

"Now focus your attention and follow along with me. I will show you how to quickly sense the spiritual energy within your body..."

As Itachi spoke, he sat down cross-legged on the spot and slowly closed his eyes.

Seeing him like this, Naruto and Sasuke immediately followed suit and also sat cross-legged on the spot.

However, Lin Yan simply crossed her arms and watched all of this with amusement, without doing anything in return.

He only said he was interested in Chakra; he didn't necessarily intend to actually refine Chakra.

Moreover, even if he refined the Chakra, he might not be able to use it.

Now, all I need to do to activate my various abilities is stamina and Haki.

Itachi noticed Lin Yan's actions, but remained silent.

Then he spoke again, reminding Naruto and Sasuke, "Calm down and feel the spiritual energy within your bodies. See if you can sense its presence."

"Only by first being able to perceive their existence can we control them to merge."

He then told the three people how to better perceive the spiritual energy within their bodies.

Naruto and Sasuke very serious.

Driven by curiosity, Lin Yan also tried to experience it.

His mind relaxed, and he entered a very wonderful state.

Soon, Lin Yan felt herself being enveloped by a cloud of mist.

The white fog all around grew thicker and thicker, and Lin Yan also felt a very strange sensation.

He felt a warm, comfortable sensation in his body after being surrounded by the thick fog.

My mental state was extremely clear, as if I had slept for eight hours.

Just as Lin Yan was feeling very curious, Itachi's voice came from all directions.

"If you can sense spiritual energy, your most direct feeling will be as if you are surrounded by mist."

"It might not be so easy at first, so you might not be able to sense much fog, and it's very likely that it won't be easily noticed."

"As you gradually master the techniques, the amount of mist you can sense, that is, your spiritual energy, will also increase."

"Of course, some people are born with a level of spiritual energy that is difficult for ordinary people to match."

"Then the fog they sensed from the very beginning would be extremely dense..."

With Itachi's explanation, Lin Yan finally understood what she was experiencing at that moment.

"Is this... my spiritual power?"

Lin Yan watched all this in astonishment, feeling somewhat surprised.

Based on Itachi's explanation, this means that I am the kind of person Itachi described as having "innately vast spiritual energy."

Lin Yan herself was completely unaware of this matter.

At this moment, he asked with some curiosity, "Is having a large amount of spiritual energy a good thing?"

Itachi was a little surprised by Lin Yan's question.

However, he remained calm and did not ask for the reason, but instead began to explain.

"The more spiritual energy a person possesses, the greater their potential Chakra reserves will be."

"Of course, I'm just saying there are quite a few possibilities."

"Because one of the factors that determines the amount of Chakra is also physical energy."

"If a person possesses both immense spiritual and physical energy, then he/she will have a greater probability than an ordinary person of being able to extract more Chakra."

"Of course, I'm still only saying it's a possibility, not an absolute certainty."

"There is a group of people who possess mental and physical energy that is beyond the reach of ordinary people."

"However, for various reasons, they were unable to refine Chakra."

Itachi further explained.
