Da Xuan Martial Saint

Having left the Ancient Courtyard, Chen Mu returned to his own residence.

Now that he had been promoted to Metropolitan Commander of the Inspectorate and had come under the wing of Yan Jingqing, some unnecessary tasks could be spared, such as moving to the Ancient Courtyard. Given the bustling nature of the Ancient Courtyard, it was more appropriate for him to stay in his own yard to quietly cultivate.

Considering the ongoing repairs in the bedroom, which were quite noisy, Chen Mu decided to dig out a space beneath the existing practice room's silent chamber to create a new training silent chamber. This would not only be quieter but also more concealed, sparing him the worry of causing too much disturbance.

So he set about doing just that.

To ensure secrecy, Chen Mu took on the task of creating the practice silent chamber himself. With his current strength, digging out a space beneath the practice silent chamber in the western room did not take much time. The only tasks were disposing of the excavated soil and reinforcing the subterranean section with specific materials to ensure its stability.

These were not problems either, as they were mostly completed along with the bedroom repairs.

...

Yu Family.

Chen Mu's residence, underground silent chamber.

Four months had passed since Chen Mu had been promoted to Metropolitan Commander of the Inspectorate. During these four months, his main activity was "observing governance," which meant only watching without acting. Apart from visiting the Inspectorate daily to sort through various intelligence documents, he spent the rest of his time cultivating.

Over these four months, the Four Great Sects in Yu County had stabilized, and had not engaged in any unscrupulous activities, hence the workload at the Inspectorate was relatively light, just like the Demon-Slaying Office, which enjoyed more freedom during times without demonic disturbances.

Thump! Thump!!

The underground silent chamber was slightly more spacious than the previous practice room. Chen Mu stood at the center, his knuckles bent and continuously tapping on a piece of raw iron in front of him, producing a dull sound like a striking bell, leaving indents with each hit!

Throughout the movement, he utilized neither Artistic Conception nor Momentum, relying solely on his own physical strength and the resilience of his skin and bones, forcefully leaving dents in the raw iron. Even disciples from the Four Great Sects would be astonished by this scene, as having such a well-trained physique was rarely seen even among the major sects.

Suddenly.

Chen Mu clenched his right fist, straightened his bent knuckles, extended his index finger, and jabbed it into the raw iron, accompanied by sparks flying and a muffled sound of metal striking iron, forcefully embedding his entire finger into the iron stone!

For Martial Artists in the Bone Tempering Realm, achieving this with the aid of "Momentum" or "Artistic Conception" wouldn't be difficult, but achieving it solely with pure strength and finger bone robustness was astonishing.

Even Xu Hongyu, who had now entered the Bone Tempering Realm, would struggle to withstand such force.

"Bone Tempering Perfection, truly extraordinary,"

With a slight exertion, Chen Mu pulled his finger out of the raw iron. Seeing that his finger remained unchanged, he then glanced at the indents left on the iron, nodding slightly with a hint of satisfaction.

[Tiger Demon Bone Tempering Technique (90%)]

[Experience: 6 points]

On the system panel, his Tiger Demon Bone Tempering Technique had remarkably reached ninety percent progress!

Just four months ago, his Bone Tempering Technique was only a slight distance away from reaching Major Achievement. Now, four months later, though he held the position of Metropolitan Commander, he had never neglected his cultivation in the Bone Tempering Method, and had now stepped into the realm of Perfection!

Even within the realm of Bone Tempering Perfection, there are differences.

Ordinarily, for someone with perfect Bone Tempering who can penetrate raw iron with pure physical prowess, penetrating as deep as a fingertip is already quite commendable. Yet, Chen Mu was able to penetrate an entire finger, which was more than double the strength!

This was not only because he had trained the three previous Realms to their limits, possessing overwhelming strength far exceeding that of ordinary people, but also because without a strong skeletal structure and without the use of Artistic Conception and other enhancements, penetrating completely and without feeling pain or sustaining injury would not be possible.

"Such a formidable physique, such robust bones, still not having reached the Bone Tempering limit of 'Jade Bone.' No wonder the Martial Canon says that if one can train all Four Realms to their limit, even the Yuan Gang True Essence from the Five Viscera Realm can be withstood with mere physical strength,"

Chen Mu muttered to himself.

With his current physique, even if he stood still, individuals not in the Bone Tempering Realm would hardly harm him, and even typical Bone Tempering Realm individuals would need to target critical areas like the eyes and throat to pose any threat to him.

As this thought flashed through his mind, Chen Mu suddenly drew his knife and swung it forward.

"Wind Thunder Shock!"

With the slash of the knife, thunder appeared and strong winds surged; the blade moved so fast it was nearly invisible, with only the fleeting thunder cutting through the darkness of the underground silent chamber.

"Windfire Blaze!"

Another slash was cast, and in an instant, blazing flames erupted from the blade. Winds fanned the flames, enhancing the fire's intensity. The blazing flames formed a visible knife shape, striking down with a loud crash, illuminating the entire underground silent chamber.

"Thunderfire Ash!"

Thunder ignited the fire, with searing flames intertwined with streaks of lightning, harboring a terrifying aura of destruction, suddenly striking down, dispelling evil spirits and clearing malevolent ghosts!

"Heaven..."

The fourth slash did not fall, merely the elements of wind, thunder, and fire intertwining on the Fine Iron Knife, then quietly dissipating.
