62: Chapter 62 Body Refinement and Iron Bones!

Spiritless Ruins, Underground Second Level, security safe room.

The gray mist quietly dissipated within the dim room, and Gu Shen's figure landed steadily on the cold refined iron floor.

The rusted mechanism behind the door remained severed, with no traces of any living creatures or Aberrations having broken in. Absolute silence and safety.

Gu Shen did not immediately begin to Cultivate. He sat cross-legged, first taking out a jar of iron-sealed meat paste and a bottle of pure water from his Storage Ring.

He swallowed the cold liquid mixed with the salty, fishy meat paste in large gulps, which transformed into a massive surge of heat that filled his limbs and bones.

Body Refining is not the same as Qi Refining; the pressure it exerts on the Physical Body's Qi and blood is extremely terrifying, so one must ensure their physical strength is at its absolute Peak.

After eating and drinking his fill, Gu Shen flipped his wrist, and the gray-white Jade Slip he had intercepted from the Blood Fiend Sect demonic Cultivator appeared in his palm.

Sending his Divine Sense inside, the cultivation method of the Bone Refining Art slowly unfurled in his mind.

"This Body Refining Cultivation Technique is truly ruthless."

Gu Shen carefully deduced it several times, a hint of sternness flashing in his eyes.

This Cultivation Technique does not focus on the internal organs, but specifically targets the two hundred and six bones of the body. Its core lies in inducing magical power like a hammer when Qi and blood are extremely full, violently striking the bone marrow from the inside out to forcibly shatter and expel Impurities, while simultaneously forcing massive vitality into the gaps of the bones.

Ordinary Cultivators practicing this method must soak in a pool of boiling Second Stage Yao Beast blood essence, enduring the pain of being skinned and having their tendons pulled, taking ten years to reach Minor Achievement. Any carelessness would result in shattered bones and becoming a cripple.

"But I don't need Yao Beast blood essence; what I have in my hand is ten times more violent than that!"

A ruthless glint flashed in Gu Shen's eyes.

With a thought.

A drop of dark green marrow fluid, resembling top-quality jade and emitting a heart-palpitating, massive vitality, floated quietly in his palm.

He tilted his head back and swallowed it.

Boom!

The moment the marrow fluid entered his stomach, Gu Shen did not use the Longevity Art to gently guide it as he had last time; instead, he extremely brutally and directly activated the method of the Bone Refining Art!

That extremely violent, mutated vitality was like a crazed Vicious Beast, rampaging through Gu Shen's body, lunging straight for his bones!

"Ugh!"

Gu Shen bit his teeth hard, the veins on his neck bulging like knotted green snakes.

Pain!

Agonizing pain deep in the bone marrow!

It felt as if thousands of red-hot steel needles were being forcibly driven through his pores into the periosteum, and then driven deep into the bone marrow! Under the guidance of the Bone Refining Art, that overbearing power of the marrow fluid transformed into invisible iron hammers, beginning to strike crazily inside his body.

Crack! Crack!

In the safe room, the crisp sound of Gu Shen's bones could be heard clearly.

Wisps of foul-smelling, pitch-black bloody Impurities seeped crazily out through his pores, staining him into a bloody person in the blink of an eye.

"Cast for me!"

Gu Shen let out a low roar like a beast in his heart.

He held onto the last shred of clarity in his mind, his Qi Refining Level 7 Divine Sense acting like a cold supervisor, forcibly restraining those violent marrow fluids and pressing them without residue into the bones that had been cracked by the shock.

Breaking and then establishing!

The pure vitality nurtured from the world-extinguishing poisonous light was not only repairing the cracks in the bones but also fundamentally changing the density of the bone structure.

The originally jade-white bones, under the crazy tempering of this power, gradually took on a cold, dark luster like black iron.

This was an extremely long and cruel torment.

A full four hours.

Gu Shen sat cross-legged in place, like an iron tower cast in blood, motionless. The black terminal iron plate tied to his left leg emitted a very faint humming sound due to the high-frequency trembling of his muscles.

"Warning... Detected that the host's bone density is rising exponentially... Bone structure is undergoing reorganization... This is definitely not a direction that carbon-based lifeforms can naturally evolve in..."

The shriveled voice of Crab came weakly through the iron plate, filled with a ghostly shock, "What kind of high-concentration radiation concentrate did you eat? The hardness of your bones now, I'm afraid even armor-piercing bullets can't penetrate them..."

Gu Shen turned a deaf ear.

Until the last trace of marrow fluid power in his body was completely devoured.

Hum.

Gu Shen opened his eyes abruptly, two extremely sharp rays of light flashing through the dim safe room.

He stood up slowly, and his entire body's bones emitted a dull sound like heavy metal rubbing against each other.

Clang, clang, clang!

It was as if a drawn sword was hidden within his body.

Gu Shen lowered his head and glanced at his arm covered in black blood scabs. He did not trigger even a shred of magical power, just clenched his fist purely and smashed it casually towards the extremely hard profound iron wall in front of him.

Bang!

A dull thud.

The profound iron wall, which could withstand the full blow of a Middle Stage Qi Refining Cultivator, was actually smashed by his casual punch, creating a clear fist print an inch deep!

And his finger bones didn't even break a bit of skin; even the pain was minimal.

Bone Refining Art, first level Minor Achievement!

"What an overbearing Physical Body! What hard iron bones!" A hint of ecstasy flashed in the depths of Gu Shen's eyes.

The efficacy of this dark green marrow fluid was terrifying to the extreme. Ten years of hard work for an ordinary Cultivator had been surpassed by him in four hours with one drop of mutated Origin!

Now, even without using the Wood Armor Technique and the thousand-tough black silk armor, just relying on this pair of iron bones and Physical Body, he could withstand the strikes of Medium Grade Magical Artifacts from Cultivators of the same rank!

What made him even more at ease was.

As his bones turned the color of black iron, he could clearly feel that the extremely weak world-extinguishing poisonous light floating in the air of the Underground Second Level, when it landed on his skin, felt like a breeze blowing over a stone, no longer able to cause him any substantial pollution or erosion.

"Immunity to poisonous light. This is the true admission ticket to the Thirteenth Underground Level!"

Gu Shen took a bottle of pure water from his Storage Ring, simply washed away the foul-smelling blood scabs on his body, and changed into a clean black short outfit.

He glanced at his Storage Ring.

He did not rush to swallow this last drop of marrow fluid. The continuous bone tempering had already reached the limit of what his Physical Body could bear; he must undergo several real battles to completely integrate this power into his instinct before he could continue to impact the next Realm of the Bone Refining Art.

"The resources of the second level have been looted almost clean. It is time to go down and take a look."

Gu Shen hung the thunder pattern gold-slaying blade on his waist, leaped up, and burrowed into the gas conduit on the ceiling again.

Following the map in his mind, he crawled all the way towards the welded-shut blast-proof door on the Underground Second Level.

Behind that door was the road to the Underground Third Level. Although the door was sealed, this hidden gas conduit could perfectly bypass the door and reach the inside of the Underground Third Level directly!

"Since this poisonous light can spawn mutated poisonous mushrooms, the further down one goes, the thicker the poisonous light, and the more mutated Spirit Medicine will be nurtured."

Gu Shen glided silently in the dark conduit.

The big shots of the Great Yu Cultivation World were fighting to the death for the blood marrow lotus.

And he, in this abandoned underground palace fortress, would step on the corpses of those Aberration monsters and gnaw out a golden road of his own, bit by bit.

The Underground Third Level, arrived.
