Bone Refining Realm Divisions!

"Dragon Skin Great Accomplishment—reaching the Dragon Skin Perfection Realm will still take quite some time. If I can get my hands on another High-grade Skin Grinding Martial Art, I'm confident I can quickly break through to the Dragon Skin Perfection Realm!"

Li Changsheng thought to himself.

His master had no more High-grade Skin Grinding Martial Arts, and he had offended the Evil Demon Society, leaving him no way to obtain another one. But there was nothing to be done about it. The Evil Demon Society had wanted to imprison him and make him refine Demon Merging Secret Medicine, so he could only choose to act at once.

Otherwise, he could have gotten several more High-grade Skin Grinding Martial Arts from the Evil Demon Society.

"I'll go trade with Cao Jun. He's a Demon Suppression Envoy of the Demon Suppression Division, after all. Though he's one of the weaker ones, he should still be able to get a High-grade Skin Grinding Martial Art, right?"

With that thought, Li Changsheng went to the Demon Suppression Division again to find Cao Jun.

"Li Changsheng, don't tell me you're here to trade demon corpses again?"

The moment Cao Jun saw Li Changsheng, a smile appeared on his face.

High-grade Secret Medicine was good stuff. He would never complain about having too much of it.

Li Changsheng shook his head. "Lord Cao, I'm not here to trade demon corpses. I want to trade for a High-grade Skin Grinding Martial Art—preferably one that polishes the skin across the entire body."

"You want to trade for a High-grade Skin Grinding Martial Art!"

Cao Jun frowned slightly. High-grade Skin Grinding Martial Arts were extremely precious, and the inner city strictly controlled such transactions. If Li Changsheng had obtained one as a reward from the Demon Suppression Division, there would be no issue. But if Cao Jun traded one to him privately, the problem would be enormous!

If it were discovered, he would not escape severe punishment.

"Lord Cao, I can offer even more High-grade Hundred Refinement Secret Medicine in exchange," Li Changsheng said. "Don't worry. I won't tell anyone about this."

"If you can produce one hundred portions of High-grade Hundred Refinement Secret Medicine, I can take the risk and give you one High-grade Skin Grinding Martial Art," Cao Jun said.

"Fine!"

Li Changsheng agreed.

One hundred portions of High-grade Hundred Refinement Secret Medicine was quite a lot, but it was only ten batches of Secret Medicine. He had already stored up quite a bit of High-grade Hundred Refinement Secret Medicine, along with High-grade White Spirit Secret Medicine and Tiger Demon Secret Medicine.

"Can I substitute other High-grade Skin Grinding Secret Medicine?" Li Changsheng asked.

Cao Jun asked, "What Secret Medicine?"

"White Spirit Secret Medicine and Tiger Demon Secret Medicine!"

Li Changsheng said.

"That works!"

Cao Jun nodded in agreement.

Though White Spirit Secret Medicine was much less effective, Tiger Demon Secret Medicine was quite good. As long as the total reached one hundred portions, he was willing to trade.

Afterward.

Li Changsheng retrieved the White Spirit Secret Medicine, Tiger Demon Secret Medicine, and Hundred Refinement Secret Medicine, all of them High-grade.

Cao Jun also brought out a High-grade Skin Grinding Martial Art, one Li Changsheng had never cultivated before.

Li Changsheng had told Cao Jun in advance not to bring martial arts like Golden Bell Shield or Iron Cloth Shirt, so Cao Jun had naturally brought another High-grade Skin Grinding Martial Art.

"Mountain Settling Stance!"

This was a stance-based Skin Polishing Martial Art. Not only could it polish the skin of the entire body, it could also greatly increase the strength of both legs and allow one to stand unmoving as a mountain. It was considered a very good High-grade Skin Grinding Martial Art.

"Pleasure doing business!"

Li Changsheng took the Mountain Settling Stance martial art and departed.

Cao Jun looked at the hundred portions of High-grade Skin Grinding Secret Medicine, his face brimming with excitement.

"Li Changsheng actually managed to get so much Skin Grinding Secret Medicine. The Alchemist he knows is no ordinary man!" Cao Jun muttered.

He did not care whether Li Changsheng had some unusual background behind him. He was merely a Demon Suppression Envoy in the outer city and did not dare investigate too deeply.

This transaction was beneficial to him, and that was enough. With so much High-grade Skin Grinding Secret Medicine, he had hope of raising his son into a Silver Skin Realm Martial Artist.

The gap between a Bronze Skin Realm Martial Artist breaking through into the Bone Refining Realm and a Silver Skin Realm Martial Artist breaking through into the Bone Refining Realm was simply too vast.

If his son broke through into the Bone Refining Realm from the Silver Skin Realm, his potential would be immense, and he might one day surpass the realm Above Viscera Realm.

So, taking a slight risk now was nothing.

At his residence.

Li Changsheng began studying the newly acquired High-grade Skin Grinding Martial Art—the Mountain Settling Stance. After studying it for a while, he began cultivating it. He smeared large amounts of Flawless-grade Tiger Demon Secret Medicine over his entire body and swiftly sensed the Mountain Settling Stance's qi and blood.

Once he sensed it, he began tempering his skin membrane according to the Mountain Settling Stance's cultivation method.

After that, his Mountain Settling Stance improved at an astonishing pace every day.

Before long, he had cultivated the Mountain Settling Stance to the Perfection Realm. He consumed vast quantities of Flawless-grade Tiger Demon Secret Medicine, and his Dragon Skin was also on the verge of breaking through to the Perfection Realm.

Two more days passed, and Li Changsheng's Dragon Skin Realm finally broke through, advancing from Dragon Skin Great Accomplishment to the Dragon Skin Perfection Realm.

Boom!!!!

A dragon's roar seemed to rise from beneath his skin membrane, as though an azure dragon were coursing through his entire body. It brought his Dragon Skin through its final transformation, while his physical attributes surged wildly.

At that moment, his physical body had reached the limit of the Skin Grinding Realm!

He also came to understand that the Dragon Skin Perfection Realm was the limit of the Skin Grinding Realm. Beyond it, there was no higher Skin Grinding Realm!

"Next, it's time to break through to the Bone Refining Realm!"

Li Changsheng muttered.

To break through from the Skin Grinding Realm to the Bone Refining Realm, one needed to cultivate a Bone Refining Martial Art, temper the bones with qi and blood, and refine the skeleton into iron bones. That was considered a breakthrough into the Bone Refining Realm.

The human body in this world was structured differently from that of his previous life. Humans here possessed a total of three hundred and sixty-five bones. Refining just one bone until it became an iron bone qualified one for the Iron Bone Realm.

Iron Bone, Bronze Bone, Silver Bone, Flood Dragon Bone, and Dragon Bone—these were the five divisions of the Bone Refining Realm.

It could be said that breaking through to the Silver Bone Realm was thirty percent harder than breaking through to the Silver Skin Realm. The main reason was that Bone Refining Secret Medicine was more precious and required greater resources, making a breakthrough to the Silver Bone Realm naturally more difficult.

To break through to the Silver Bone Realm, he would also need a High-grade Bone Refining Martial Art. Yet the Bone Refining Martial Art his master Xu He had taught him could only be cultivated to Bronze Bone Realm Perfection.

The human body had three hundred and sixty-five bones. Even a top-tier mid-grade Bone Refining Martial Art could only complete the tempering of thirty-six bones. However, different Bone Refining Martial Arts involved different bones, so one could cultivate more Bone Refining Martial Arts to temper more bones.

A High-grade Bone Refining Martial Art, meanwhile, could temper one hundred and eight bones. That was why High-grade Bone Refining Martial Arts were extraordinarily precious.

Li Changsheng did not possess a High-grade Bone Refining Martial Art at present, so he could only first cultivate the top-tier mid-grade Bone Refining Martial Art his master had given him—the Azure Steel Bone Refining Fist. This martial art could temper thirty-six bones throughout the body.

As for a martial art capable of tempering all three hundred and sixty-five bones at once, it was likely only the legendary Ultimate Skill-grade Bone Refining Martial Art.

"Many High-grade Skin Grinding Martial Arts can polish the skin membrane across the entire body, but High-grade Bone Refining Martial Arts cannot temper all the bones of the body. It seems I must collect more High-grade Bone Refining Martial Arts and strive to refine all three hundred and sixty-five bones in my body."

Li Changsheng thought.
