Achieving physical sainthood begins with the Iron Shirt technique!

After forcibly consuming that pile of high-level immortal pills, the Extreme Dao Small Blood Furnace within Lu Chen's body roared wildly.

The dark skin, which had been somewhat withered by the violent spiritual energy of the immortals, now swelled up again, radiating a dazzling dark golden light.

He twisted his neck, his joints making a series of rough, cracking sounds, and his depleted blood and energy were completely restored to their peak.

Scattered on the ruined ground were several low-grade flying swords, their immortal array patterns recently erased. These flying swords were originally the executioners' weapons, exuding a chilling aura. Lu Chen kicked away the rubble with his large black iron boots, casually grabbed a few flying swords with his rough hands, and tossed them directly to the one-armed old man in the distance.

"Here you go! Take it and get to work!" Lu Chen's rough voice boomed through the camp.

The one-armed old man reached out with one hand and firmly grasped the sword hilt. After looking down at the object in his hand, a wild smile spread across his gaunt face, and he threw his head back and laughed loudly.

"Hahaha! What a treasure!" The old man forcefully slammed the flying sword into the hard, scrap ore, which shattered with a crack. "This lofty celestial treasure is actually a superb tool for manual labor! This is the blessing bestowed upon us earthworms by the immortal masters, saving us costs and increasing efficiency! Men, young and old, using this scrap metal to chisel stones is far more efficient than beheading people!"

Thousands of survivors burst into laughter. Normally, they would have their hands and feet chopped off if they even touched anything belonging to the immortal sect. Now, these powerful weapons had been reduced to mining tools. This extreme contrast made all the resentment in their hearts vanish.

Dozens of strong miners rushed forward to snatch the flying sword. Even without the power of a celestial being, the blade remained incomparably sharp. The men found thick black iron and wooden sticks, and used hemp rope to tightly bind the flying sword to its tip, instantly converting it into an iron pickaxe for chiseling through rock walls.

The strong men, shirtless, swung their "flying sword iron pickaxes" and hacked furiously at the incredibly hard black iron ore vein.

Clang! Clang!

The immortal swords sliced ​​through iron like mud, and large chunks of heavy iron ore peeled off. Rock layers that would normally take ten days to half a month to break through were now cleaved open in just a few strokes, instantly increasing mining efficiency by hundreds of times.

"Everyone, give it your all!" Lu Chen shouted from his high vantage point. "Dig all these mine pits horizontally! Those pseudo-immortals in the sky have cut off our livelihood, so let's carve out a lifeline for the remnants of the Great Wilderness right here underground!"

"Listen to Master Lu!" the crowd roared, their enthusiasm completely bursting forth.

On the other side of the defense line, Xiao Anan crawled out of Lu Chen's tattered leather pouch, using both her hands and feet.

The little girl, with her short legs, ran to a huge basalt rock used for building fortifications. This rock was enormous and was specifically used to fill the gap in the city wall where the camp gate had been destroyed.

A dozen or so old men, their faces flushed red, tightened thick hemp ropes around their shoulders and struggled desperately to drag the seemingly indestructible boulder. Sweat soaked their backs, and the stone wore deep grooves into the ground; progress was extremely slow.

A-Nan stood to the side, her Ancient True Vision Eyes swirling wildly beneath her Blood Jade Eye Robe.

In her unique perspective, the interior of this unshakeable boulder was filled with intricate lines, and she could see through the most vulnerable spiritual vein node at a glance.

A-Nan pouted, staring disdainfully at the uneven edges of the basalt, muttering that this broken stone couldn't possibly fit perfectly into the city wall.

She stretched out her chubby little hand and placed it directly on the edge of the boulder. Her chubby fingers accurately gripped one of the hidden cracks.

Without needing to exert any force, the little girl simply pried it out gently.

A deafening cracking sound erupted. The entire massive basalt rock, its internal structure completely disintegrated and crumbled under that single finger. Large sections of the stone collapsed, leaving behind an absolutely smooth cut surface.

The old men, who were desperately dragging the stone, suddenly felt the rope loosen, and more than a dozen of them lost their balance and fell flat on their backs. They lay on the ground, mouths agape, staring at the extremely smooth cut of the stone, unable to utter a single word for a long time.

Lu Chen stomped his heavy black iron boots on the ground and burst into a hearty laugh.

He strode forward, just as he reached out his large, thick hand to ruffle the little girl's messy hair.

From the depths of the dark tunnel behind, a young man suddenly tumbled and crawled out. The man's face was full of terror, his limbs were weak, and he collapsed directly in front of Lu Chen.

"Master Lu! Something terrible has happened!" The man trembled, his voice hoarse. "Our main underground well... has completely dried up! Not a single drop of mud can be extracted!"

The survivors working around them suddenly stopped, a wave of despair washing over them. Being underground without water was tantamount to stepping directly into a coffin.

Lu Chen suppressed his smile and strode to the main well opening with a fierce expression.

Looking down, the bottom of the well was completely dried up, leaving only cracked yellow mud.

Lu Chen stood still, his eyes closed. He didn't need any immortal divine sense; his body, honed by extreme physical cultivation, was extremely sensitive to the vibrations from the earth. His senses traveled down his legs, penetrating deep into the earth's veins.

Within three breaths, he detected an extremely subtle fluctuation of magical power emanating from the deepest part of the earth.

This is definitely not a natural interruption of the flow!

Lu Chen opened his eyes, his rough face filled with a ferocious killing intent.

Those cultivators in the sky secretly set up the [Marrow Extraction and Spirit Gathering Array]! Seeing that a direct attack was futile, these bastards used this vicious array to forcibly intercept the water veins of the Eastern Xuan Land, stripping away all the spiritual energy and water sources, intending to kill everyone here with thirst.

Lu Chen snorted coldly and pulled the century-old black iron chain wrapped around his right arm.

He bent down, gripping the bottom edge of the Primal Bone-Suppressing Stele with both hands. His back muscles tensed, bearing the terrifying weight of 110,000 jin (approximately 65,000 kg) directly onto his shoulders.

Lu Chen strode to the low-lying area at the very center of the camp and suddenly stopped.

"Everyone, retreat ten zhang!"

The roar shook the earth, sending it tumbling down. Thousands of survivors quickly retreated, clearing the area completely.

Lu Chen's feet were firmly planted in the mud. Instead of blindly digging with the black tablet, he used his extreme senses to lock onto the tiny rock fissures created by the underground marrow extraction array.

The small blood furnace in his chest cavity throbbed with thunder, and his dark gold blood energy erupted in full force.

Lu Chen's arm muscles suddenly swelled. The tenfold Abyss Force Field, which originally covered a radius of ten zhang, was forcibly pulled back by him with extreme brute force. The enormous pressure was compressed inward to its limit, and firmly concentrated in that small area at the bottom of the black monument.

The violent death force, carrying a million-pound pressure, slammed heavily into the cracks in the ground along the base of the monument!

boom!

The earth shook violently, and this deadly force traveled along the fault lines of the rock strata, resonating downwards without any regard for reason.

Lu Chen raised his large arm.

Boom! Boom! Boom!

In just a few breaths, dozens of consecutive heavy blows slammed into the same point of force.

The extreme resonance grew increasingly intense deep underground. The immortal marrow-extraction array hidden deep within was simply unable to withstand the violent destructive power of this resonance. The array's patterns shattered directly, emitting a crisp cracking sound.

The underground formation collapsed on its own!

Freed from its magical restraint, the underground river flowed wildly. The pent-up, raging water surged upwards through the fissures. The terrifying water pressure eroded the area in the opposite direction, instantly carving a massive crater in the low-lying center of the camp.

A column of water shot into the sky, reaching mid-air, and was about to submerge the surrounding camp in the blink of an eye.

Lu Chen faced the oncoming torrent, grinned widely, and with his thick arms he embraced the 110,000-pound black monument, thrusting it fiercely into the gushing water column!

The black monument is positioned horizontally directly in the center of the fountain's outlet.

The tenfold abyss force field was released again. This immense power formed an invisible, oppressive barrier, forcefully diverting the torrent to both sides. The water could not flow upwards and could only obediently rush outwards along the ditches on both sides.

Lu Chen placed one hand on the monument and stomped heavily on the ground with his large black iron boots.

With sheer, extreme power, he forcefully suppressed and carved out a completely dry mineral deposit in the center of this raging swamp, free of any water accumulation!
