Achieving physical sainthood begins with the Iron Shirt technique!

The black monument was firmly wedged in the center of the fountain's outlet. The raging torrent was forced to split to both sides, and the low-lying area in the center of the camp was forcibly suppressed by a gravitational field ten times stronger, creating a dry mineral deposit.

The silt was all swept away by the water flow, and the cliff face deep underground was completely exposed to the air.

The grayish-brown rock strata were densely studded with palm-sized, azure stones. A rich, natural water system seeped outwards from the cracks in the rock, tinging the surrounding air with moisture.

This is a hidden vein of water-elemental crystals deep underground. Just now, those cultivators in the sky set up a marrow-extracting and spirit-gathering array, which accidentally shattered the outer layer of rock on the surface of the vein.

Lu Chen's large feet stomped on the edge of the mud, and his rough voice boomed across the mining area.

"What the hell are you all standing there for?"

"Good fortune never falls from the sky! Now that you've dug it up, why don't you hurry up and jump down, waiting for those old immortal dogs to pay you your wages!"

The old man's emaciated chest heaved violently, his remaining hand gripping tightly the flying sword and pickaxe that had just been tied with a wooden stick. His eyes were bloodshot, and he was the first to let out a hoarse roar.

"Master Lu has spoken!"

"Brothers, uproot this immortal!"

Hundreds of burly, remnant villagers went completely mad. These laborers, who had been exploited for half their lives, with red eyes, rushed to jump into the safe zone cleared by the force field.

The rough, distinctive work chants of the people of the Great Wilderness echoed loudly in the underground mine.

These men brandished the once-important treasures of the immortal sects, relying solely on their bare arms for strength, without any magical enhancement.

Clang! Clang!

The sharp blade of the flying sword slammed into the hard rock. Large chunks of the rock were cleaved and peeled away.

In the past, miners had to be careful not to damage the rough stones, but now no one cares about that. Regardless of the size of the rough stone, they roughly pry it off from the base. Any stone that glows blue is stuffed into tattered sacks and carried away.

This group of descendants of the lower lands used the most primitive blood, sweat, and magical artifacts to complete the most hardcore mining of the spiritual minerals of the Eastern Xuan Earth.

In less than half an hour, tens of thousands of water spirit crystal ore stones were piled up in the open space of the camp, forming a small mountain that shimmered with blue light.

Lu Chen grinned from ear to ear, and his rough hand suddenly swung in mid-air.

"Get that biggest black iron pot in the warehouse set up for me!"

"Place it directly next to the ore deposit!"

The able-bodied young men immediately set to work, carrying over a black iron cooking pot that was half a person's height and weighed several hundred kilograms.

Lu Chen strode to the small hill of raw stones, casually fiddling with his large black iron boots. These low-grade raw stones contained too many impurities; directly absorbing them with the Extreme Dao Blood Furnace would be too much trouble.

"Get all these tens of thousands of broken stones and use them to build a solid wall around the outer perimeter of the stockade!"

Lu Chen turned to the old man and gave him an order.

"Keep it as a foundation stone! Later, when you guys work inside, you can use the chill emanating from this stone to temper your skin and hone your skills!"

After saying that, he quickly rummaged through the pile of stones with his large, rough hands. In just a short while, relying solely on his sense of touch, he accurately selected several hundred of the clearest core mineral marrow pieces, each shimmering with liquid blue light.

Lu Chen piled the mineral marrow next to the black iron pot, turned around and filled the pot with water, then ordered people to throw all the captured pieces of the great demon's flesh into the water.

The dozens of miners around stared wide-eyed, completely bewildered by what was going on. Cultivators who obtained mineral marrow would find a cave rich in spiritual energy, carefully holding it in their hands to absorb its essence.

Lu Chen sat cross-legged directly in the mud pit under the black iron pot.

His arm muscles bulged, and he grabbed two of the clearest core mineral marrows in each hand.

There was absolutely no crude action of chewing and swallowing raw.

The Great Wilderness devours all things, never relying on eating dirt.

Lu Chen clenched his fists, and his thick knuckles instantly gleamed with a dark golden light. The tenfold abyss force field that originally covered the surrounding area for ten feet was ruthlessly drawn back by him and terrifyingly compressed into his two palm-sized hands.

"Snap!"

An extremely piercing cracking sound exploded in Lu Chen's palm.

The incredibly hard mineral marrow, which even flying swords could hardly cut through, crumbled on the spot in the face of this unreasonable, extreme compressive force.

The impurities inside were crushed by the force field.

A few drops of the extremely cold, blackish-brown "Water Spirit Liquid" dripped directly into the large iron pot above Lu Chen's rough fingers.

Lu Chen spread his palms out, and the once incredibly precious mineral marrow had now turned into two handfuls of completely ash-white stone dust. He raised his hand and casually tossed the waste onto the muddy ground, then grabbed four more pieces of mineral marrow and continued to crush them.

The clicking sounds were incessant.

Hundreds of priceless core mineral marrows were completely extracted by Lu Chen's bare hands in less than the time it takes for an incense stick to burn. All the spiritual liquid was then absorbed into the pure demon meat broth in the pot.

"Get the hell out of my way!"

Lu Chen roared, driving away the surviving civilians who had gathered to watch the spectacle.

He sat in the mud pit at the bottom of the pot, his broad chest suddenly straightening. Inside his chest cavity, the Supreme Blood Furnace emitted a thunderous roar.

Pure Yang blood fire surged forth from the major tendons on his back.

Lu Chen didn't use ordinary fire at all. He used his own supreme yang blood fire as the furnace fire, directly burning it fiercely against the bottom of the pot!

The liquid inside the large iron pot boiled instantly.

The Water Spirit Liquid is an extremely cold creation of heaven and earth. At this moment, it senses the tyrannical and unreasonable extreme yang blood fire at the bottom of the pot and instinctively produces an extremely violent repulsion.

Blue and red lights swirled and clashed wildly inside the pot. A deadly sense of expansion erupted from within the black iron pot.

This is a harbinger of two incompatible extreme energies that are about to trigger a terrifying spiritual explosion!

The cauldron emitted a violent hum, its lid being tossed about by the raging deathly aura. Extremely chilling deathly aura poured down the cauldron's rim, viciously attacking Lu Chen's body sitting at the bottom.

A thick, solid layer of bone-chilling frost instantly formed on Lu Chen's jet-black skin.

The cold air penetrated violently into the large pores.

Within Lu Chen's body, tons of heavy iron were forcefully scraping and tearing through his flesh and blood, causing every inch of his meridians to undergo extremely cruel tearing and reconstruction. Large chunks of bone emitted cracking sounds as they could no longer bear the weight.

A world of extremes, both ice and fire – this is the most brutal and agonizing form of extreme cruelty.

Lu Chen's feet were firmly planted in the mud, not retreating an inch. The stubble on his chin was covered with frost, and instead of suppressing his fiery temper, he pushed the pure yang energy in his chest to its limit.

"Melt it for me!"

Lu Chen roared and suddenly raised his hands upwards.

The tenfold abyssal force field did not suppress the outside world, but instead directly inverted onto the black iron cauldron!

The violent, frigid energy tried to explode the iron pot, but it crashed head-on into the unshakeable, overwhelming force of 100,000 jin.

Lu Chen endured excruciating pain, akin to being cut into a thousand pieces, with his own body as the price, serving as the stabilizing center of the entire alchemy process.

Under this unreasonable and violent suppression, the arrogant, cold, and malevolent aura within the Water Spirit Liquid was completely ground to dust by the Chongyuan Force Field and the Pure Yang Blood Fire in the black iron pot.

The originally incompatible essences of extreme cold were forced to yield, forcibly binding together with the blood and qi of the great demon beast in the pot, fusing into one.

The white frost quickly faded from the Lu Chen skin.

The crackling sound from the iron pot ceased, and a rich, medicinal aroma, so strong that just one whiff could make one's blood boil, filled the air above the Seventh Mining Area.

The miraculous medicine has been created.

Lu Chen put away the Pure Yang Blood Fire and lifted the scalding hot iron pot with one hand.

The pot was full of a thick, dark red liquid.

Lu Chen forcibly suppressed the convulsing and trembling meridians throughout his body, picked up the edge of the black iron pot with both hands, tilted his head back, and directly poured the most concentrated half of the essence medicine at the bottom of the pot into his stomach.

The medicine entered the stomach, and the violent energy exploded instantly.

Lu Chen clenched his teeth, and the Extreme Blood Furnace ran wildly, directly burning away the last bit of demonic beast impurities and mineral vein poison in the medicine inside his stomach.

Blood and qi surged wildly through the limbs and bones.

Lu Chen raised his right arm, his rough thumb resting on the tip of his index finger, and suddenly bit the pad of his finger.

His arm muscles contracted wildly, forcing the vast life force that had just been absorbed and purified within his body to converge along the tendons to the wound at his fingertips.

Tick.

A drop of supreme true blood, a deep, dark gold color, was forcibly forced from the fingertip. This drop of true blood contained not even a trace of violent or malevolent energy, only the gentlest and purest life force of creation.
