Fox Demon: Heaven rewards diligence; I will eventually achieve divine mastery of martial arts.

Several boilers were continuously distilling liquor, filling the air with a rich aroma of alcohol.

In the very center of the courtyard, a large vat contained a black liquid that was bubbling and gurgling under the heat of the flames below.

A figure appeared and disappeared amidst the rising steam.

Through the steam, one could vaguely see specks of dark blackness emerging.

A gentle breeze blew by, dispersing the steam in the air.

Lin Yu's face appeared in the large vat.

Unlike his usual self, his skin now looked as if it had been coated with a layer of iron paint, making him resemble some kind of sculpture at first glance.

However, upon closer inspection, one can see that some skin on the surface of the dark water is being rapidly corroded by the eerie black boiling water.

This is clearly a pot of highly corrosive liquid.

If it were anyone else, falling into this pot, they would probably have been corroded to the point of being nothing but ashes, let alone the scalding boiling water.

But Lin Yu sat there calmly, completely unmoved by the pain he was experiencing.

They didn't seem worried about getting hurt at all.

I don't know how much time had passed, but then I heard the sound of water.

A figure with bulging muscles and an imposing aura leaped out of the large vat.

His dark, iron-colored skin was now tattered and mangled, as if it had been subjected to some kind of torture.

In some places, the injuries were so deep that the bone was visible, a sight that sent chills down one's spine.

Lin Yu looked down at his miserable state, but instead of being afraid, he grinned.

"The poison from this southern border is truly potent."

As he spoke, Lin Yu casually picked up a thick spiked club leaning against the side, and with a swift swing, he smashed it down on himself, creating a whooshing sound.

"boom!"

A muffled sound rang out, and blood and flesh flew everywhere.

The corroded skin and muscles could hardly withstand such heavy beatings.

The dark iron-colored skin quickly faded away with each beating, replaced by bright red muscle beneath.

Such a bloody scene would probably make anyone else faint from fright.

However, Lin Yu seemed to have already taken it all in stride, continuing his actions without changing his expression.

Lin Yu only stopped moving when the black iron color on his body completely disappeared and dark blood flowed all over the ground.

Dropping the spiked club, Lin Yu bent his knees slightly and assumed a horse stance, the clear sound of his heartbeat beginning to echo in his chest.

"Boom, boom, boom!"

As the heartbeat grew louder, a surge of vital energy began to flow.

Under Lin Yu's control, the muscles and bones in his body began to tremble strangely under the influence of his qi and blood.

The bleeding stopped quickly, and the wounds on his body began to shrink.

Under this tremor, Lin Yu, who had just looked as if his skin had been peeled off and he was covered in blood, began to have his injuries heal rapidly.

The corroded muscles, the pierced wounds, the torn skin—everything was regenerating at a visible rate.

Moreover, during this regeneration process, a faint silver hue began to emerge.

Lin Yu wore a faint smile as he watched all this astonishing happening, seemingly unsurprised as if he had expected it all along.

At this moment, the prompts on the system panel in front of him clearly revealed everything.

[Your Nine Revolutions Body Tempering Technique has been upgraded to LV.5 (0/8000), and your understanding of the Nine Revolutions Body Tempering Technique has improved.]

Nine Revolutions Body Tempering Technique.

This is the product that Lin Yu deduced after combining the Mighty Bull Technique, Cloth Armor Body Technique, and Rejuvenation Technique.

In order to ensure that the three cultivation techniques could be developed in tandem, Lin Yu also spent a lot of money to buy a lot of monster meat.

Thanks to the boost to proficiency from the monster meat.

Lin Yu spent a lot of time forcibly raising his Rejuvenation Technique to level four, and he was about to break through to the next level.

Of course, the same applies to cloth armor.

After the progress of the three cultivation methods was unified, Lin Yu then combined them into one and integrated them into a whole.

This led to the Nine Revolutions Body Tempering Technique!

A surge of heat, like a tsunami, continuously washed over Lin Yu's body.

Internal organs, bones, muscles, skin.

Where the heat flowed, the already steel-like body became even more solid and strong.

As the sunlight fell, the gleaming silver on that muscular, streamlined body was exceptionally dazzling.

Chapter 44 Silver Skin and Iron Bones, Vajra Body

This silver hue seems to possess a life of its own.

It spreads throughout the body at a visible speed, and then gradually deepens.

Under the sunlight, Lin Yu's tall and majestic body looked like a statue carefully sculpted by the Creator, or a god descending to earth, displaying his supreme majesty and magnificent power.

After a long while, the heat in his body slowly dissipated.

Lin Yu looked down at his body, which resembled the third young master of Aolai Kingdom, his body gleaming with silver light, and chuckled to himself.

"It's really eye-catching."

However, he was not surprised.

In fact, the cloth armor had already begun to show signs of its presence on the way to the National Youth Games City.

When I first leveled up to level two, it was fine; there wasn't much of a difference. But things changed when I reached level three.

Lin Yu still remembers that when he broke through to the next level, his skin turned bronze.

At first, Lin Yu thought it was the effect left by his physical exertion and didn't pay much attention to it.

But when the cloth armor was upgraded to another level, the bronze color changed, turning into a deep, dark iron black.

Based on the insights gained from each upgrade in his mind regarding the cloth armor body.

Lin Yu then realized that this was a change resulting from the continuous upgrades of the cloth armor body.

Each color represents a different stage.

After combining the Cloth Armor Body Technique with the other two techniques, this evolution and improvement became even clearer.

When the Nine Revolutions Body Tempering Technique is upgraded to the sixth level, the silver color will turn into gold.

As he spoke, Lin Yu clenched his fist tightly, and a loud "bang" was heard in the air.

The two fists collided slightly, producing a deep metallic clang, and sparks flew in the air.

"Not bad, but I don't know if it can block the flying swords of cultivators."

Lin Yu twisted his neck, and the blood and qi in his body quickly calmed down. The silvery light on his body also gradually dissipated. He stared at his body and said thoughtfully.

After this tempering, not only was the previously strengthened body further enhanced, but even the internal organs were strengthened.

Moreover, after the Nine Revolutions Body Tempering Technique was combined with the Rejuvenation Technique, Lin Yu's recovery ability was greatly enhanced, and his resistance to some poisons was also significantly improved.

Otherwise, Lin Yu wouldn't have dared to use the poison he collected from the Southern Kingdom's demon race to temper himself so recklessly before.

Fortunately, it is no longer necessary to do so nowadays.

After further improvements, Lin Yu discovered that he had completely mastered the latent power of qi and blood within his body.

Although it can't compare to internal energy.

However, the power of Qi and blood can also be manipulated to enhance one's own strength, but it cannot leave the body.

With his control over the power of Qi and blood, Lin Yu was able to temper his body from within through vibration.

Both the effect and efficiency far exceed those of the past, when external forces were needed to achieve the same results.

"Based on my progress pattern, roughly speaking, starting with the skin, I'll train the skin, muscles, bones, and internal organs. The body parts are basically all tempered. Perhaps the next step will bring different changes?"

Lin Yu turned around and went back into the house, changed his clothes, rubbed his chin, and pondered to himself.

"However, that's still quite far off for me right now. The priority right now is to figure out the techniques as well."

With his gaze fixed on the Crimson Fiend Fist, Lin Yu tidied up the courtyard, turned around, and walked out.

Lin Yu hadn't forgotten about techniques during this time and had been exploring them continuously.

However, unlike martial arts techniques, Lin Yu needs to personally experience and integrate the skills to truly master them.

Arriving at the street, we walked towards the outskirts of the city.

It's fine for him to practice the Nine Revolutions Body Tempering Technique in his own little courtyard, but if he were to explore the techniques with his current strength and cultivation level, it would probably cause quite a stir.
