Chakra Training (II)

Counting today, Uchiha Yue had been learning to cultivate chakra for three months, and had managed to build up a modest amount.

However, in Uchiha Yue's mind, cultivating a certain amount of chakra was only the first step. To truly learn how to use the chakra within his body, he needed to develop some chakra control. So, familiar with the original story, Uchiha Yue decided to start practicing tree climbing to improve his control over the chakra in his body.

As it turned out, Uchiha Yue had enough control over his chakra to climb up a tall tree.

But because he didn't have enough chakra, he eventually fell out of the tree and passed out.

Having suffered while practicing tree climbing, Uchiha Yue was all the more focused on cultivating chakra. He needed to build up a certain amount of chakra before he could complete the training.

Moreover, while practicing tree climbing, Uchiha Yue discovered the first advantage he'd gained from crossing over: his spiritual energy was extraordinarily vast!

Ordinary people couldn't cultivate spiritual energy. The spiritual energy in the human body could only increase as a person grew older. But Uchiha Yue was different. When he'd first crossed over, he'd already possessed an adult's soul, and his spiritual energy far surpassed that of an ordinary infant. As time passed, because his spiritual energy was already greater than other people's, Uchiha Yue possessed nearly ten times as much spiritual energy as others his age.

That enormous amount could only grow over time, never diminish!

His abundant spiritual energy not only gave Uchiha Yue a photographic memory, but also allowed him to control his body—and the chakra within it—perfectly.

Now that Uchiha Yue knew about the advantage his spiritual energy gave him, he began searching through countless ninjutsu scrolls for a way to use it to increase his chakra reserves.

However, to Uchiha Yue's slight disappointment, even after reading all the ninjutsu scrolls before him, he still hadn't found a way to increase his chakra quickly.

"Alas, crossing over for real is a little different from the kind of crossing over described in novels!"

After reading all the ninjutsu scrolls about chakra cultivation, Uchiha Yue sighed deeply and thought to himself:

"In those AU Naruto stories, the protagonist either has a heaven-sent talent for cultivation or can keep the Eight Inner Gates open permanently to increase their chakra and physical strength."

"Too bad! It's all a lie!"

"To open the Eight Inner Gates, you first need a strong physique. Otherwise, opening even the first gate could leave you permanently disabled!"

"Sure enough, novels are all made up. If I want to build up my chakra reserves, I'll just have to work at it slowly!"

Thinking this with resignation, Uchiha Yue set the ninjutsu scrolls aside and sat down cross-legged to cultivate chakra.

At the same time, Uchiha Yue understood that there were no shortcuts on the path of cultivation. He could only rely on his own efforts.

After all, chakra was produced by combining spiritual energy and Body Energy. Though Uchiha Yue's spiritual energy was extraordinarily vast, his body was holding him back. With plenty of spiritual energy but not enough Body Energy, the chakra he could store in his chakra pathways could only be accumulated bit by bit over time and through tireless effort.

But...

Just as Uchiha Yue sat down cross-legged, ready to focus on cultivating chakra, he suddenly made a new discovery!

"Huh? How is this possible?"

"M-my spiritual energy has already built up enough for me to see inside my body?"

According to the records in some ninjutsu scrolls, Uchiha Yue knew that, aside from ninja with special Kekkei Genkai, only a very small number of ninja could see inside their own chakra pathways!

And when Uchiha Yue calmed his mind and prepared to cultivate chakra, he discovered that his spiritual energy was already sufficient to see inside his chakra pathways!

This unexpected discovery filled Uchiha Yue with delight!

He knew that as long as he could see inside his chakra pathways, he would surely be able to find a better way to build up his chakra!

In his previous life, Uchiha Yue had been good at analysis. After crossing over into the world of Naruto, he made full use of that ability. So, as he worked to grow stronger, the first thing he did was study as much theory as possible, then put it into practice bit by bit.

The ninjutsu scrolls Uchiha Nara had given him were just what Uchiha Yue needed to build up a solid base of theoretical knowledge. Though he had only just started cultivating chakra, his theoretical knowledge of chakra cultivation could already rival that of some elite Chunin and even some Jonin.

Moreover, his photographic memory made it easy for Uchiha Yue to analyze and sum up the difficulties on the path of chakra cultivation.

Now that Uchiha Yue's spiritual energy was also sufficient to see inside his chakra pathways, he could make some innovations to his existing chakra training!

That gave Uchiha Yue an extraordinary advantage in cultivating chakra, putting him far ahead of other geniuses his age.

"Seeing inside my body... It really does help with chakra cultivation!"

Once he'd calmed his excitement, Uchiha Yue, now able to see inside his body, resumed training and quickly discovered the benefits of doing so.

Originally, Uchiha Yue had followed the most basic method of chakra cultivation. It relied on his abundant spiritual energy to instinctively draw out the Body Energy contained in every cell in his body, then combine it into chakra and store it in his chakra pathways. But after successfully seeing inside his body, Uchiha Yue discovered that ordinary chakra training methods could only draw on a third of the Body Energy in each cell.

Simply put, if he followed the ordinary method of chakra cultivation, two-thirds of his Body Energy would go to waste!

Since there was no reason to waste it, how could Uchiha Yue stand by and let all that Body Energy go to waste?

So, the first thing Uchiha Yue did after learning to see inside his body was make full use of the Body Energy within him, combining it with his spiritual energy to form chakra!

His lack of Body Energy had always been the bottleneck preventing Uchiha Yue from building up his chakra reserves!

Now, Uchiha Yue could make perfect use of every bit of Body Energy in his body, and the speed at which he cultivated chakra shot up like a rocket!

And when Uchiha Yue had used up the last bit of his Body Energy, he discovered that the results of this cultivation session were ten times better than usual!

If he could maintain this pace, Uchiha Yue was confident he could have Genin-level chakra reserves within six months!
