On the other side, deep within the courtyard of Changgong Lane.

After removing his disguise, Gu Yuan wiped the blood-stained long knife clean and hid it in the ceiling beam.

Yang Jianfei, was naturally killed by him.

This guy was like a mad dog, biting people randomly, and he already hated him to the core.

Gu Yuan certainly would not let such a hidden danger live.

Killing him to eliminate future problems was the best solution.

The dead enemy is the best enemy!

Moreover, Beiliang County has become increasingly unstable lately, with frequent chaos, perfect for framing someone else, and Wei Chuan was a good candidate.

The more muddled the water, the better it was for him.

In fact, since he previously created the "Yan Shisan" identity, Gu Yuan felt he had awakened a certain hobby.

Good deeds can be ignored, but as for some dirty business, some trivial matters that need to be taboo, can entirely be handled by the alternate identity.

The killing was done by Yan Shisan, what does it have to do with me, Gu Yuan?

After killing Yang Jianfei, he felt clear-minded, free of distractions, and his mood had eased a lot.

And this matter was behind him now, the next step was to calm his mind and earnestly cultivate.

Gu Yuan stopped thinking about it, took out a Red Jade Bone Forging Pill, and swallowed it in one gulp.

This thing was expensive, but indeed worth every penny.

A wave of warmth quickly rose within him.

As the medicinal power dispersed, Gu Yuan began to fall into the Turtle Breath state, circulating his qi and blood to temper his bones, while also honing his physique.

While his qi and blood were consumed quickly, they were also supplemented by the medicinal power.

In this state, Gu Yuan found that not only did the "Black Turtle Armor Technique" progress rapidly, but even his Bone Refining accelerated significantly.

The bone itching and occasional unbearable stinging were hard to endure.

But in the Turtle Breath state, Gu Yuan felt like he was bathing in a spring breeze, not affected at all.

It had the meaning of "eight winds cannot move me, myriad pains do not deter my heart."

Even the most difficult bones to refine, like the spine and skull, were being tempered and nourished systematically and orderly.

...

Half a month later.

In the courtyard.

Buzzing... buzzing...

Gu Yuan's back seemed curved, his arms encircling, his body swaying, posing a Golden Snake Shedding Stance.

And all the bones in his body, including the skull, vibrated and trembled together, making strange sounds.

The muscles covering his body were affected, sometimes swelling, sometimes smoothing, sometimes twisting, as if cramping.

Underneath the fair and smooth skin, a dense layer of blue-black tendons had grown much thicker than before.

Once his muscles swelled, the skin became smooth and tough, exuding a jade-like sheen!

This gave Gu Yuan a terrifying and sinister ferocity.

As if beneath the human skin, a great demon grinding its teeth and sucking blood was hidden!

During this half month, Gu Yuan focused on cultivation.

Without any distractions, supplemented by the Blood Jade Bone Forging Pill and Spirit Medicine Yellow Spirit, his progress was swift.

Now, he had reached the critical phase of Bone Refining!

As his whole body trembled, Gu Yuan only felt weak and powerless, aching and itching.

Unbearable pain, soreness, twisting pain, and numb itching all struck at once.

On his gums, the teeth started to loosen and bleed.

This was a process of transformation!

Gu Yuan endured the pain, took out the last piece of Yellow Spirit from his pocket, and shoved it into his mouth.

It had traces of purple lines on it, it was the five hundred-year-old Spirit Medicine Yellow Spirit.

The medicinal power of this Yellow Spirit was much purer and more massive than the hundred-year-old one!

After swallowing it, as the medicinal power spread, the transformation seemed to intensify.

"Damn, this is too painful!"

Gu Yuan's face twisted, veins bulging on his forehead, gritting his teeth in pain, and hissing through clenched teeth.

"No wonder the Bone Refining phase is a threshold, many people are stuck in this phase their whole lives. But once it reaches Great Success, there's an opportunity to refine the viscera, nurture True Qi, and become an Innate Martial Master."

Bone Refining is a meticulous task, requiring enough patience and perseverance, step by step, without the slightest laxness or carelessness.

But one cannot rush, or else a slight misstep might damage the bones, making it difficult to achieve Great Success in Bone Refining.

Common Martial Masters wishing to refine bones often take many years, slowly grinding bit by bit, requiring the patience of water torture.

Better to go slow than make mistakes.

Taking seven or eight years to achieve Great Success in Bone Refining is already very good.

As for Gu Yuan, he was an exception.

Gu Yuan calmed his mind, falling into Turtle Breath state.

His breathing became slow and long, his state of mind pure and calm, undistracted.

The effect of the pain on him seemed to gradually fade away.

In this state, Gu Yuan coolly circulated his qi and blood, methodically tempering his bones, especially the top of his skull, repeatedly subjected to the washing of qi and blood.

After a long while, Gu Yuan opened his eyes.

Swoosh!

A glint of light flashed in his eyes!

The abnormal changes in his bones had calmed down within him.

Gu Yuan moved slightly, feeling his movements smooth and coherent, nimble and flexible, his qi and blood flowing smoothly and rapidly through his entire body.

His overall power, speed, and reaction ability had all greatly improved.

Especially the increase in power, which had soared several times over!

Gu Yuan reached out and grasped, lifting a stone table weighing hundreds of pounds next to him, swung it a few times as if it were a straw, making whooshing sounds, almost weightless to him.

After putting down the stone table, Gu Yuan suddenly felt something strange in his mouth.

Poof!

He opened his mouth and spat out several teeth.

The white teeth rolled a few times on the ground, with bloodstains still on them.

"Changing teeth... isn't this something that happens after a martial artist is promoted to an Innate Martial Master? How come I started losing teeth now?!"

Looking at the teeth on the ground, Gu Yuan was taken aback.

The promotion from Martial Master to Innate Martial Master is a threshold.

After becoming an Innate Martial Master, one often goes through a period of tooth replacement, old teeth falling out, new ones growing, which is also a hallmark of stepping into the realm of Innate Martial Master.

But he clearly was just a Martial Master now!

"Could it be, because my bone talent is better, and I've also trained in Horizontal Martial Arts, so my foundation is better?"

Gu Yuan formed a hypothesis.

Perceiving the other teeth in his mouth also becoming loose, his tongue nudged, and a few more fell out.

Now, with his mouth open, he started to have a bit of wind blowing through.

Gu Yuan felt a bit awkward, thought for a moment, and simply used two fingers to pull out all the loose teeth.

After pulling them out, his mouth felt empty, quite uncomfortable, and his cheeks had sunk in.

His originally handsome face now looked sharp and monkey-like.

This made Gu Yuan feel a bit uncomfortable for the first time.

It turns out that without teeth, a person can become so ugly!

Fortunately, Gu Yuan noticed his gums itching, and when he touched it with his finger, tiny new teeth had already emerged at the gum line.

In the mirror, they appeared whiter, more delicate, more orderly, firmer, and seemed to have a kind of crystalline feel.

At this rate, it seemed all the teeth would soon grow back, restoring his handsome appearance.
