In middle age, one's comprehension becomes extraordinary.

I got plenty of rest on the high-speed train.

After returning home, Li Yuan did not lie down to rest.

Take the USB drive and plug it into the computer.

There is a PDF file on the USB drive.

The file name was the cultivation technique Xia Zhao had mentioned earlier, "Heavenly Gang Body Refining".

Xia Zhao explained this set of techniques quite clearly.

"Tian Gang Body Refinement" is a basic cultivation method that was once pursued by countless powerful individuals who risked their lives to obtain it.

But once they actually got their hands on it, these powerful individuals discovered a major problem.

I can't understand it, or rather, I can't comprehend its content.

In their understanding, the content of this practice method is wrong.

It's possible that the "Heavenly Gang Body Refining Manual" they obtained was fake.

Or perhaps the rumors about it are all false.

The supposedly powerful effects of "Heavenly Body Refinement" simply do not exist.

Li Yuan didn't waste his energy thinking about these things; he'd just have to see for himself how it went.

Li Yuan opened the file and began reading this basic cultivation method.

The content of the cultivation method was somewhat obscure, and even Li Yuan found it difficult to understand.

You need to combine what you think in your mind and simulate the practice scenario in your mind.

Both move in tandem, which helps to understand the meaning behind it.

The document also contains many annotations, which were likely left by Xia Zhao.

It marks some of her thoughts and understandings.

Li Yuan's first reading involved removing all annotations and focusing solely on the original text.

After you have read through the entire book, then look at these annotations yourself to avoid being misled and going astray.

Li Yuan returned home at nine o'clock in the morning.

I was looking at this document and it was already evening by then.

For more than eight hours, nearly nine hours, Li Yuan felt completely immersed in it.

This set of "Tian Gang Body Refining" is indeed difficult to understand.

Reading it, it's more like a more challenging version of "Cloud Extreme Fist".

For the average person, it takes at least half a day to digest a single page, and they often misunderstand it.

In the past nine hours, Li Yuan has read through "Tian Gang Body Refining" once.

I wouldn't dare say that my understanding is correct, but based on my understanding, this "Heavenly Gang Body Refining" set doesn't contain any errors.

This is a sophisticated and profound method of spiritual practice!

After reading it once, Li Yuan still hadn't fully grasped its meaning.

However, from my own understanding, its greatest mystery lies in its internal energy.

This basic training method helps martial artists condense their own internal energy (罡气), which they then use to temper themselves.

Others should also be able to understand this part.

But if they delve any deeper, they won't understand.

According to "Tian Gang Body Refinement", one must temper oneself with Qi, and one must also temper one's own Qi.

In other words, physical strength and inner energy are mutually reinforcing.

Both should be improved simultaneously.

Others don't understand this at all.

The reason why people feel there is something wrong with the practice method also stems from this.

To them, forging one's physique and cultivating one's inner strength is clearly self-destructive.

Since qi is formless, wouldn't tempering it with one's own body damage one's physique?

The crucial point arises at this moment.

The reason why the basic cultivation method of "Tian Gang Body Refinement" is named as such is that it aims to completely integrate the Qi (罡气) with one's own physical body.

Practicing this method will indeed damage one's physical body.

These damaged areas are where the protective energy (罡气) takes effect.

The protective energy transforms into armor that attaches to the body, coexisting with flesh and blood to form a protective barrier.

When cultivation reaches its peak, the Qi and physical body will be completely integrated to form a Qi Body!

Seeing this, Li Yuan understood why it was so popular.

With such powerful effects, no ordinary cultivation method can compare.

Conventional basic training methods strengthen the body at three levels: cells, bones, and fascia.

The path of "Tian Gang Body Refining" is completely different from other basic cultivation methods.

From a certain perspective, "Tian Gang Body Refining" is more like a cheating cultivation method.

Practicing this method results in a physique with strength far exceeding that of martial artists at the same level, due to the intervention of internal energy.

Others would probably need to be a whole grade higher to achieve the same level of physical strength!

A fifth-rank martial artist possessing an exceptional physique comparable to a sixth-rank martial artist sounds like a fantasy.

He went downstairs and bought some food for dinner. After eating, Li Yuan began reading it a second time.

On this second reading, Li Yuan started looking at the annotations on the document, and his reading speed increased significantly.

Li Yuan read all of these annotations.

In Li Yuan's understanding, most of the annotations were wrong.

It's about understanding "Tian Gang Body Refinement" with preconceived notions.

If you try to understand things with this kind of thinking, the final result will definitely not be good.

Those top-tier masters and grandmasters, because of their own experiences and expertise.

They actually find it harder to understand "Heavenly Body Refining".

The study of other basic spiritual practices can take decades or even centuries.

Their understanding of basic spiritual practices has long been ingrained, and it takes a long time to change their preconceived notions.

Now that you understand it, the next step is to put it into practice.

Sitting cross-legged on the bed, Li Yuan began to try circulating his qi and condensing it.

Martial arts training is known to be a long-term endeavor that requires perseverance.

Spiritual practice is a very time-consuming and energy-intensive activity; it cannot be completed in just one or two days.

Even though "Heavenly Gang Body Refining" isn't that difficult to understand, it still takes more than half a year to cultivate Gang Qi.

But at this moment, Li Yuan, relying on his [Martial Arts Quick Mastery] talent, began to try to condense his inner energy.

There was a faint layer of mist on the surface of the skin.

The mist slightly lifted the clothes underneath.

In just one hour, Li Yuan successfully condensed his initial internal energy.

In fact, besides "Tian Gang Body Refining", many other cultivation techniques require the condensation of Qi.

Especially many protective techniques and defensive skills.

However, "Tian Gang Body Refining" is a basic cultivation method.

A technique that condenses internal energy to temper one's body—that was truly the first time I'd ever seen one.

The mystery of this technique lies precisely here.

With the Qi successfully condensed, Li Yuan began to activate it, using it to temper his physique.

At the same time, one's physical body is also being tempered by the Qi.

There's a feeling of interaction, collaboration, and mutual improvement.

A moment later, I felt a sharp pain in my body.

This is a warning sign of physical damage.

According to the "Tian Gang Body Refining Manual," this is the normal procedure for practicing this set of techniques.

Next, the internal energy merges with the physical body.

A protective aura will firmly cover the body.

At this moment, this layer of protective energy will be more than just a protective shield.

It will constantly hone your physique, and your physique will constantly refine it.

This is somewhat similar to the "Zhou Tian Dao Yin Shu" (a type of exercise).

However, this basic cultivation method is far superior to the "Zhou Tian Dao Yin Technique".

Both sets of exercises can be used to continuously temper one's physique.

As one's inner strength and physical constitution gradually improve, the effects of the hammer-forging also increase in a spiral.

However, the "Zhou Tian Dao Yin Technique" not only fails to improve one's abilities, but its effects become increasingly ordinary due to the improvement in one's martial arts realm.

In addition, the protective energy itself has the effect of protecting the body.

Practicing this basic cultivation method is simultaneously training a top-tier body-protecting technique!
