Achieving physical sainthood begins with the Iron Shirt technique!

In the deep, black, foul-smelling mud, the Lord of Xuanni City was half-buried under rotten leaves.

His old face turned purple from holding his breath, and his teeth were grinding together.

Suppressing the excruciating pain from the shattered golden core, he forced out the last two drops of true essence from his depleted dantian and poured them all into the magic weapon on his left index finger.

The spike on the fingernail, the "Curse-Killing Finger," instantly emitted an extremely dense, corrupting black light.

This is a deadly poison that can kill instantly. If you aim it at that big guy's neck from a distance, even if his body is tough, it will still leave a bloody hole the size of a bowl.

Just as the city lord, his face contorted with resentment, was about to fully activate the magical artifact at this critical juncture...

A major blunder has occurred!

The dark red "wild blood" that he had secretly absorbed at the very core of his golden core, which was originally used to forcibly prolong his life and break through realms, suddenly began to boil violently without warning!

This wisp of wild blood, usually so docile, now seemed like a wolf that had smelled the blood of its ancestors, going completely mad and rebelling.

Because it's deep inside a cave, several dozen feet away.

The thousand-layered Extreme Blood Furnace in Lu Chen's chest cavity is currently in the most vigorous and violent stage of backflow after the medicinal effects have been removed!

The domineering and extreme yang blood of the same origin directly generated an extremely tyrannical "bloodline pull" in the air!

Lu Chen, with his orthodox Desolate Bone Body, straddled the black sky for over ten zhang and firmly grabbed the wisp of impure stolen Desolate Blood within the City Lord's body!

This is the absolute and overwhelming advantage that the ultimate body cultivator has over the blood-stealing immortal cultivator; it makes absolutely no sense.

"Ugh—!"

The Lord of Xuanni City suddenly shuddered violently, as if he had been struck head-on by divine lightning from the heavens.

The reversed flow of true energy surged wildly through the meridians, instantly turning the internal organs into a pot of mushy porridge.

His chest suddenly thrust upwards, and with a muffled "plop," mouthfuls of scalding, poisonous blood mixed with blackened pieces of internal organs gushed out uncontrollably.

The black light gathered at the fingertips exploded on the spot.

The priceless curse artifact, having lost its true essence, slipped off the fingernail with a thud and fell completely into the bottomless, foul-smelling swamp, without even a ripple.

His attempt to steal a chicken backfired; the old man was in so much pain he couldn't even scream, and could only twitch in the mud like a dead dog.

However, the large mouthfuls of blood he spat out were genuine essence blood of a cultivator, containing the remnants of a Golden Core.

In this desolate wilderness where spiritual energy is scarce and poisonous creatures abound, these few mouthfuls of blood were like a bucket of boiling oil, poured straight into a raging fire!

Deep underground.

Suddenly, a dense rustling sound came from the air, sending chills down one's spine.

The sound was initially very soft, but in the blink of an eye it coalesced into a terrifying, ear-splitting cacophony.

The muddy ground, within a radius of a hundred feet, began to churn violently.

Thousands upon thousands of "Bone-Eating Poisonous Centipedes," each over half a foot long and covered in barbed black armor on their backs, smashed through the soil and burst forth!

These giant venomous insects were gushing out yellowish-green, highly toxic mucus from their mouthparts. Hundreds of their segments were scrambling through the mud and water, surging forward like a tidal wave, drawn by the scent of the tainted blood and golden pills spat out by the city lord.

Once this kind of ferocious creature, unique to the Great Wilderness, takes shape, it can kill even a Core Formation cultivator, let alone a Foundation Establishment cultivator!

The city lord was so frightened that he almost lost his mind, and no longer cared about seizing the treasure or killing anyone.

He trembled as he pulled a top-grade concealment array plate from his waist, crushed it on the spot, and a dim light shield completely covered him.

He forcibly sealed off all the pores of his body, even forcing his heartbeat to stop at a rate of one beat every half incense stick's time, stubbornly pretending to be a lifeless piece of rotten wood.

The first to charge out, the poisonous centipedes, having lost their target, flailed their two tentacles wildly in mid-air.

Immediately afterwards, tens of thousands of poisonous insects simultaneously turned their densely packed compound eyes.

They smelled a scent that was more attractive to insects.

That was the immense medicinal fragrance emanating from the century-old ginseng and the flesh and blood of a great demon, which had been boiled together in a large cave several dozen feet away, along with the vibrant life force of more than a hundred living people gathered together!

The black, venomous waves instantly changed direction, riding the eerie winds of the wilderness, and surged wildly towards the entrance of the cave!

The outermost edge of the cave.

Li Laosi was gripping the broken, chipped pig-slaughtering knife, leaning against the rock wall and staring at the heavy rain outside.

Suddenly, the tiny blood furnace that had just formed in his chest cavity began to vibrate extremely strongly.

This is a unique, instinctive warning that body cultivators experience when facing a life-or-death crisis, making every single hair on their body stand on end!

Li Laosi kicked it out.

He kicked the pile of dry firewood that had just been lit and was emitting a faint flame, sending it tumbling away.

The sparks were blown outwards by the wind.

Using the fleeting light of the fire, Li Laosi could see what was rushing towards him from a dozen feet away.

His scalp scalp instantly exploded, and all the muscles in his body tensed to their limit!

It was a layer of black waves made entirely of large, venomous insects, densely packed and compressed, advancing towards the cave at an extremely terrifying speed.

The swarm of insects passed over a patch of low bushes.

Several low-ranking wild boars that were taking shelter from the rain inside were swallowed up by the black waves before they could even grunt.

In just three breaths.

After the dark romance, only a few pale, brittle skeletons remained on the spot.

The skin and flesh were completely corroded by the yellowish-green slime, and pungent white smoke was still rising from the bones!

This visceral scene of destruction left the miners guarding the perimeter completely dumbfounded.

Panic erupted instantly among the group of laborers.

"My God! I can't live like this!"

A gaunt miner let out a howl, threw away the scraps of copper and iron he had painstakingly collected, and turned to run scramble and crawl toward the deepest part of the cave.

This sudden run terrified the dozen or so miners, who turned around and tried to rush inside as well.

"Bang!"

A deep, muffled bang.

Li Laosi pounced like a furious black bear, grabbing the neck of the fleeing miner with his large hand, lifting him up and slamming him against the hard, rough stone wall!

The miner's feet were dangling in the air, his face flushed red, as he struggled desperately.

"Stop right there, all of you!"

Li Laosi's eyes were bloodshot, and a murderous glint, like real blood, shone directly from the depths of his eyes.

He turned his head and stared intently into the deepest part of the cave.

In front of that large stone slab.

Lu Chen, the benefactor, was sitting cross-legged, his two thick, strong hands pressed firmly against the outer wall of the scorching black iron alchemy furnace.

Lu Chen was emitting large plumes of hot steam and white smoke from his entire body.

He didn't even turn his head; he was completely trapped in a dead end, unable to move.

A sudden realization dawned on Li Laosi.

He was someone who had just touched the threshold of the ultimate body cultivation, and he understood it instantly.

My benefactor just now forcibly refined the great medicine and healed himself. At this moment, he is at the critical juncture of life and death, where he is finishing the flow of his blood throughout his body. He must not be interrupted!

If these venomous insects rushed into the cave, even the slightest noise or a drop of venom would disturb the raging pure yang blood.

Our benefactor will absolutely suffer an unimaginable and devastating backlash, and may even go berserk and explode on the spot!

"Our lord tossed us that gleaming white immortal sword as a stepping stone, granting us a chance to stand up straight and be human again!"

Li Laosi's arm, gripping the butcher knife, throbbed with veins as he roared at the hundred-odd trembling miners behind him.

The sound caused dust to fall from the cave ceiling.

"Our hundred or so worthless lives should have rotted at the bottom of the immortals' mine long ago!"

Even if these bedbugs outside eat us to bits today, leaving not a trace of bone!

"We absolutely must not let them take even half a step inside, lest they disturb our benefactor's arrival!"

This extremely crude declaration was filled with bloodshed.

As soon as he finished speaking, Li Laosi suddenly raised his left hand.

He slashed the dulled butcher knife hard across his left wrist!

A deep blood groove instantly ripped open.

The scalding hot blood of the Extreme Path surged out, pouring all of it onto the broken iron blade, producing a sizzling sound like a branding iron.

This is the most hardcore blood oath ever!

Li Laosi shoved aside the terrified miner in his hand, picked up the blood-dripping butcher's knife, turned around abruptly, and used his broad back to face the overwhelming swarm of doomed insects outside the cave.

The hundred or so miners behind them were already having cramps in their calves.

Their eyes turned completely red as they watched the hot blood spurting from Li Laosi's wrist.

Servility was utterly crushed, and the fighting spirit in their bones was ignited!

"I'll risk it all! Even if it means death!"

"Protect our benefactor!"

These emaciated men gritted their teeth.

They bent down and picked up the broken iron spears, blunt iron hooks, and even sharp stones that had just been thrown on the ground.

More than a hundred people were lined up in formation.

At the entrance of this dimly lit cave, a wall of flesh and blood formed, blocking the only way forward for the toxic tide!
