In chaotic times, one can become a martial immortal.

The crimson aura, once it left the sword, instantly pierced through the boulder in front of it.

You can even see that the cut surface is charred black.

"The destructive power of this Blazing Sun Sword Qi is indeed much stronger than that of the sword light."

Lu Yuan sheathed his sword and stood there, a slight smile appearing on his lips.

Most importantly, the sword energy can injure enemies from a hundred paces away, and its power is even more terrifying than the finger flick technique combined with an iron bullet.

It can be said that with the Blazing Sun Sword Qi as his trump card, even a ninth-rank expert who has truly mastered the Iron Skin technique can be dealt with calmly, and he may even have a chance to turn the tables.

Besides the Blazing Sun Sword Technique, Lu Yuan has also truly mastered the Skin Polishing Chapter of the Five Elements Vajra Body in the past ten days.

[Introduction to the Five Elements Vajra Body Skin Polishing Technique (111/5000)]

In addition to the changes in the progress of the ancient scroll, a trace of internal energy was also generated in Lu Yuan's dantian.

The emergence of this wisp of internal energy also signifies that from this moment on, he has truly entered the ranks and is now a ninth-grade martial artist at the Skin-Refining Realm.

Next, he only needs to continue to use his internal energy to refine the skin all over his body until it becomes as tough as iron.

After successfully entering the ranks, Lu Yuan finally understood why Master Song had said that without entering the ranks, one is ultimately just an ant.

The difference between unapproved and approved items is like heaven and earth.

Its essence lies in internal strength.

The mystery of internal strength far surpasses that of qi and blood.

First, the efficiency of internal energy in tempering and nourishing the physical body far exceeds that of qi and blood.

Secondly, internal energy can also strengthen the body's foundation and nourish its vitality, so there is basically no need to worry about the decline of qi and blood.

Alternatively, it could be said that once a martial artist reaches a certain rank, the concept of a "golden age" no longer applies.

Even if one is over thirty years old, one can still steadily improve one's cultivation level.

Most importantly, the power unleashed by using internal force to drive techniques is much stronger than that of blood and qi, especially the blade and sword auras that are generated, which are several times more destructive.

In short, once a martial artist possesses internal energy, they experience a comprehensive leap forward.

It wouldn't be an exaggeration to call it a qualitative transformation.

"Right now, even in the entire Qinghe County, I should be considered one of the few top experts."

Lu Yuan stood with his sword in hand, a glint of shrewdness in his eyes.

Of course, he was also well aware that once he left Qinghe County and entered the wider world of martial arts, his journey to the next level was only just beginning.

Above the Ninth Grade Skin Refining Realm, there is the Eighth Grade Flesh Refining Realm.

Above the eighth rank, there are also the seventh, sixth, and even first ranks.

Even in the simplest area of ​​skin smoothing, there is a significant difference.

A few days ago, in the backyard of Guangchun Hall, Huang Hui mentioned many details of the Ninth Grade Skin Polishing Realm during a casual chat.

"For ordinary ninth-rank martial artists, achieving an iron-like skin might already be the goal of this realm. After reaching the Iron Skin realm, they can directly attempt to break through to the eighth-rank Flesh Refining realm. However, for true geniuses, it is still just the beginning. They can continue to advance towards the Bronze Skin realm, and even the Gold Skin realm!"

"However, without exceptional talent, ample resources, and even the aid of precious medicines, achieving a bronze-level skin might be possible, but a gold-level skin is simply out of reach!"

Huang Hui also warned Lu Yuan that once he truly reached the highest level, he must not blindly pursue the gold skin.

Although gold skin is much tougher than iron and copper skin, it not only requires a lot of resources, but also consumes a great deal of time and effort.

Cultivation is ultimately the foundation of a martial artist; no matter how powerful the Golden Skin is, it is difficult to make up for the gap in cultivation level.

While he was pursuing the Golden Skin, others might have already broken through to the eighth-grade Body Refining Realm, or even reached above the eighth grade.

Simply put, if one's innate talent is not exceptional and there are not enough resources to support them, after reaching the ninth rank, one only needs to cultivate iron skin to directly attempt to reach the eighth rank.

If one has exceptional talent, ample resources, and even precious medicines to aid them, then they can try to achieve copper skin or even gold skin.

Ultimately, the best course of action depends on individual choices.

Of course, Lu Yuan didn't need to make a choice.

He could have either the golden skin or the cultivation level.

Although his proficiency level increased to 5,000 after mastering the Five Elements Vajra Body Skin Polishing Technique, he was still able to achieve minor mastery of it in a short period of time.

Once you've achieved a certain level of proficiency, you can train yourself to have iron skin.

By analogy, after mastering the skill, one can obtain copper skin, and upon reaching perfection, one can obtain gold skin.

Although the skin-polishing chapter of cultivating the Five Elements Vajra Body and the consumption of condensing internal energy far exceed that of the Transformation Realm, with the assistance of the Rejuvenation Pill and the Qi and Blood Pill, it is still possible to at least maintain a progress of three training sessions a day.

Furthermore, with the Blazing Sun Sword Technique now fully mastered, he can now dedicate all his time and energy to refining his skin membrane.

After taking a Rejuvenation Pill and a Qi and Blood Pill, Lu Yuan continued his cultivation.

He could clearly sense that when the trace of internal energy in his dantian began to circulate throughout his body's skin, every inch of skin seemed to be repeatedly hammered and refined.

The membrane trembled slightly, as if a faint buzzing sound followed.

With each circulation of his internal energy, Lu Yuan seemed to faintly feel a real change in the membranes of his entire body.

He finally stopped after about an hour.

[Introduction to the Five Elements Vajra Body Skin Polishing Technique (317/5000)]

After this training session, my proficiency increased by almost two hundred.

In addition, Lu Yuan also discovered that his body was not only soaked in sweat, but also mixed with some black substance, which should be the impurities discharged after the skin membrane was tempered and polished.

However, polishing the skin membrane consumes internal energy, and condensing internal energy requires a large amount of qi and blood. Even with the help of qi and blood pills, it is still difficult to continue.

After resting for a short while, Lu Yuan put a piece of blood ginseng in his mouth and entered a state of cultivation again.

And so, for the next few days, Lu Yuan spent most of his time cultivating at home.

As progress continues, the Five Elements Vajra Body Skin Polishing Chapter is nearing completion, and the Iron Skin is in sight.

Even so, Lu Yuan still had no intention of showing off.

Only by keeping a few more cards up your sleeve can you gain a little more confidence.

He now has only one thought: to quickly develop iron skin, and then strive to develop copper skin or even gold skin before the martial arts exam.

……

The next day, early morning.

Lu Yuan returned to Guangchun Hall.

The moment he stepped into the backyard, almost everyone who was practicing stopped their movements.

Not only did they voluntarily give up the best spot, but some people even clasped their hands in greeting and addressed him as Master Lu.

Although Lu Yuan was very young, even a few years younger than them, only a seventeen-year-old boy, in their eyes he was already a senior who was even more powerful than Master Huang.

Zhang Feng was quick-witted and immediately brought him a large piece of meat from the cafeteria.

Chen Zhenghe, Wang Chao, and others also eagerly took turns serving him tea and water.

Even Manager Yu took the initiative to bring him Qi-boosting soup and Yuan-boosting soup.

That's human nature; when you're powerful, everyone around you is a good person.

"Lu Yuan, do you want to make a fortune?"

Just as Lu Yuan was about to leave, Master Huang walked over with a smile on his face.

"Master Huang, please explain in detail!"

Lu Yuan's eyes brightened slightly, and he smiled directly.

Although his current cultivation resources are basically provided by the Zhou family, and he still has most of the century-old blood ginseng left, he still needs money, and the more the better.
