Chakra

The next morning, Uchiha Mika brought Uchiha Cheng to a mountainous area on the outskirts of the village.

The air here was fresh, filled with the scent of flowers and the songs of birds. The sun had just risen, and the lingering chill of the night in the air made one involuntarily perk up.

Uchiha Mika naturally supported her child's desire to learn ninjutsu with all her might. Although she had hoped to let him rest for a while longer, she had reluctantly agreed after Uchiha Cheng's insistent pleading. However, she never once thought of letting her child be the one to protect her.

As for that beast, she had already made a firm decision in her heart.

To provide Uchiha Cheng with the best support, she had specifically chosen this location; the quiet and beautiful scenery helped calm the mind, which was highly beneficial for cultivation.

Fortunately, she had taken an extended leave from the hospital to care for her child, which gave her the extra time to guide him in his training.

"The scenery here is truly quite nice..."

Uchiha Cheng stretched, his sleepiness not yet fully faded from waking up so early.

Thanks to the restorative abilities of his Senju bloodline, he had already made a full recovery today, despite having been dancing on the edge of death just yesterday.

"Mom, why aren't we going to the Uchiha Clan training grounds? Why come to this more remote place instead?"

Uchiha Mika found a relatively flat rock, spread out a mat, and explained.

"The first step in ninjutsu training is learning to refine chakra. When refining chakra, mental tranquility is of the utmost importance.

The Uchiha Clan training grounds have people coming and going constantly. While that place is suitable for practicing ninjutsu, for someone like you who is learning how to refine chakra, a quieter environment is far more efficient."

After speaking, she beckoned Uchiha Cheng to her side and had him sit cross-legged on the mat. She began to explain the various key points of refining chakra.

To ensure he understood better, Uchiha Mika had made many detailed preparations.

As his mother spoke, Uchiha Cheng gained a much deeper understanding of chakra refinement.

First, chakra was not like the internal energy in the martial arts novels he remembered, which was usually stored in the dantian and mobilized during combat.

Chakra could not be stored unless one possessed special secret techniques. If refined chakra was not used, it would slowly dissipate over time, even if it remained in the meridians.

Under normal circumstances, chakra was extracted and used on the fly.

Of course, one could generate a large amount of chakra before a battle, allowing for immediate use during combat without needing to divide one's focus to refine it.

However, this also resulted in a waste of chakra, because the timing of a battle was unpredictable. It was fine for a short duration, but over time, the chakra would dissipate.

Precisely because of this, the ability to refine a large amount of chakra in an instant was one of the standards used to measure whether a ninja was excellent.

Elite ninjas like Kakashi Hatake from the original story could generate large amounts of chakra while engaged in intense combat with enemies, allowing them to unleash various ninjutsu.

In contrast, there was Naruto Uzumaki when he first encountered Uchiha Itachi. He stood there frozen for a long time just to generate enough chakra, only for it to be devoured in a single strike by Kisame Hoshigaki.

Secondly, chakra was the product of an equal mixture of spiritual energy and physical energy. Mental tranquility helped facilitate chakra cultivation.

As for the method of refining chakra, simply put, it involved mixing spiritual energy and physical energy within the body in a spiral pattern.

Uchiha Mika spoke at length, explaining every little trick clearly, fearing that any oversight might hinder Uchiha Cheng's cultivation.
