Begin your practice with the crane-shaped stance.

Inside the secret chamber at the bottom of the well, it was so quiet you could hear a pin drop.

Xia Dong sat cross-legged and put the purplish-black "Purple Blood Contaminated Pill" that gleamed with a ghostly light into his mouth. The pill melted instantly upon entering his mouth, turning into a strange saliva with a slightly fishy and sweet taste.

This immense medicinal power did not spread wildly into the limbs and bones like ordinary tonics, but under Xia Dong's divine sense, it transformed into a stream of heat that flowed straight into the depths of his chest and abdomen.

Xia Dong immediately closed his eyes and focused his mind on introspection.

The powerful divine sense at the fifth level of Qi Refining is like a bright lamp that illuminates the darkness, revealing the previously hazy and invisible "inner landscape" within the body in every detail.

He clearly "saw" that the purplish-black medicinal power, upon touching his internal organs, transformed into thousands of fine, thread-like purple spiritual patterns, densely clinging to his fragile internal organs.

With each long, deep breath, the purple medicinal power seeped deeper into his body.

The fragile internal organs, which were originally dull in color during the Bone Forging Realm, were gradually tinged with a lustrous luster like purple jade under the nourishment of this immense vitality, and their pulsation revealed a sense of substantial weight.

"Thump...thump..."

The steady, powerful beating of a heart echoed in the sealed room.

As a deep "humming" suddenly emanated from within his body, as if a long-sealed door had been pushed open, Xia Dong's pores opened, instantly expelling a thin layer of dark red, fishy sweat.

He has reached the Inner Strength Realm of Martial Arts.

At the moment of breakthrough, the blood and qi in the body are like a river bursting its banks, as if summoned by some mysterious force, and begin to converge wildly towards the kidneys at the back of the waist and abdomen, like all rivers flowing into the sea.

To Xia Dong's utter astonishment, not only his boiling blood and qi, but also the Xuan Yin magic power that he had painstakingly cultivated and which resided in his dantian, resonated joyfully at this moment.

This cold and profound magical power also deviated from its original circulatory trajectory, plunging headlong into the wildly beating kidney.

At that moment, as if struck by a sudden inspiration, he realized that there was a strange and profound connection between the demonic cultivation method of the "Mysterious Yin Scripture" and martial arts training.

The kidneys govern water, are located in the far north, and are associated with the color black.

This attribute undoubtedly aligns with the yin and yang nature of the Xuan Yin magic.

At this moment, each powerful pulse of his kidneys was not only purifying his martial arts qi and blood, which was as pure as lead and mercury, but also continuously refining his profound yin power. Under the furnace of qi and blood, the originally cold and dark profound yin power was refined to have a sense of profound weight, which was full of vitality and continuity.

Xia Dong was completely immersed in this wonderfully subtle sense of control.

He realized that although he had only just entered the inner strength realm of martial arts, his keen observation of every subtle change in his body had already touched the threshold of the legendary "seeing the god" in martial arts.

For ordinary martial artists without divine sense, trying to see the transformation of their internal organs in the Inner Strength Realm is like the blind men and the elephant; they can only rely on the experience of their predecessors and the feedback from their own bodies to struggle relentlessly.

Only by cultivating to an extremely profound "true realm" and generating divine will can one achieve this level of palm reading.

He, relying on the divine sense of a cultivator, forcibly acquired this ability to see his own body before the refining stage.

He slowly opened his eyes, a dark blue-green light flashing in his deep pupils.

Now, his Xuan Yin magic power is not only more solid, but it also seems to have a natural "divine palace" as a refuge.

With every gesture, qi and blood and magical power intertwined and blended within his body, and one could faintly hear strange sounds coming from within him, such as the roar of dragons and elephants and the howling of lions and tigers.

Xia Dong let out a long sigh of relief.

"laugh!"

The airflow was like a tangible, grayish-white arrow, striking the hard stone wall of the secret chamber with a crisp sound, leaving a deep white mark on the stone wall!

Qi sword.

This is the true power of the internal organs.

A martial arts master at the Inner Strength Realm, having cultivated to an extremely high level, possesses lungs and internal organs as strong as bellows, capable of killing with a single breath.

Such techniques are generally only fully mastered and easily used by experts at the Transcendent Realm.

However, with the aid of his divine sense, Xia Dong's control over every bit of his own qi and blood might not even be comparable to that of an ordinary Transcendent Realm martial artist.

Of course, he has never actually seen a true Transcendent Realm expert; all of this is just his private speculation.

However, what he was truly concerned about at this moment, and even felt his heart pounding, was another major matter concerning the foundation of his cultivation—the hidden and perfect resonance between the Xuan Yin magic power and martial arts training, especially with his kidneys.

However, this kind of dual cultivation, which involves both the internal organs and the magical power of immortality, would undoubtedly be a waste of time if one were to try to figure it out on their own like a blind man touching an elephant.

"Fortunately, I have an ancient bronze bell."

Without the slightest hesitation, Xia Dong's mind instantly sank into the depths of his consciousness.

In the center of the vast and boundless sea of ​​consciousness, an ancient bronze bell, weathered and covered with the patina of time, floats silently in the darkness, exuding an aura of vicissitudes that suppresses everything.

Xia Dong flipped his wrist and took out many spirit stones from his storage bag.

Guided by divine sense, the pure spiritual energy within the spirit stone was drained and poured into the ancient bronze bell like rivers flowing into the sea.

The spirit stone, having lost its spiritual energy, turned into a pool of grayish-white powder.

"Buzz".

The ancient bell, having absorbed enough spiritual energy, trembled slightly and emitted a grand and desolate chime that struck the depths of the soul.

Time seemed to lose its meaning in the sea of ​​consciousness.

After an unknown amount of time, a brand new secret technique exuding a dark aura slowly manifested as twisted scarlet characters on the mottled bell.

Xia Dong eagerly probed with his divine sense, reading the secret information deduced by the ancient bell with great thirst.

"So that's how it is... Cultivation techniques can actually be combined with martial arts in this way!"

The results of the deduction completely overturned Xia Dong's previous understanding of the "Mysterious Yin Scripture" and even the cultivation techniques of the entire cultivation world.

It turns out that the reason why the power of the "Mysterious Yin Scripture" resonated so perfectly with his kidneys was because the core and most secret concept of this ancient technique was to use extremely domineering "internal organ training" methods to forge an indestructible "internal organ palace" in the kidneys, which belong to the water element in the human body!

According to the revised and improved version of the "Mysterious Yin Kidney Refining Technique" derived from ancient bronze bells:

Once this "Kidney Water Divine Palace" is successfully forged within the two kidneys, it will seize the creation of heaven and earth, naturally evolving into a miniature "Creation Divine Pool".

The water in this divine pool is no ordinary water. It is formed by the extreme compression and fusion of the kidney essence and pure Xuan Yin magic power of the human body, and is called "Xuan Yin Divine Water".

This Mysterious Yin Divine Water is a wondrous substance of utmost yin and gentleness in the world, perfectly blending the power of immortal cultivation with the extremely precious essence of the human body.

When facing an enemy, once it is unleashed, it can have a powerful restraining effect on fire-based magical spells.

On the other hand, because this Xuan Yin Divine Water contains abundant life essence and pure magic power, if it is used to assist in alchemy in the future, it can neutralize the medicinal properties and slightly improve the quality of the final pills.

Martial arts train the body, immortality cultivates the spirit.

The two elements subtly form a perfect closed loop within this "Mysterious Yin Kidney Refining Technique".

Little did he know that this was the most orthodox secret transmission of the Xuan Yin Scripture, which could not be passed down to the collateral branches or ordinary disciples of the Xuan Yin Sect.

"Once the Profound Yin Divine Water is complete, it seems we can start thinking about how to refine pills."
