Achieving physical sainthood begins with the Iron Shirt technique!

The dimly lit underground stone chamber was so stuffy that it was hard to breathe.

Anan lay on the cold, sheer bluestone bed, her once fair face now flushed red, her forehead covered in layers of fine beads of sweat. The immense, purified life force of the fourth-tier Cold Pool Yin Dragon surged wildly within the little girl's still-developing body, displaying an extremely domineering and irrational frenzy.

This tyrannical medicinal power, belonging to a high-level demon, completely disregarded whether the host could withstand it. The demon's essence transformed into boiling magma, rushing wildly along the delicate meridians, threatening to sever these passages.

Anan clenched her teeth in pain, her small body convulsing uncontrollably. A dangerous, blood-red light emanated from beneath her skin, and she even writhed in agony on the stone bed. The internal strain caused by the high-level medicine was pushing her to the brink of life and death.

Lu Chen sat cross-legged on the edge of the bed, his brows furrowed into a deep frown.

Seeing the little girl's pained expression, he reached out his large, calloused hands, which were used to wielding heavy weapons of black iron for many years, and grabbed her. His broad palms pressed down firmly on the girl's arms, which were twitching and throbbing wildly.

With this pressure, Lu Chen restrained the brute force of his 100,000 jin ultimate cultivation to the extreme, fearing that he might break the little girl's arm with a single exertion. He used his powerful black flesh to forcefully suppress this out-of-control struggle, lest her delicate skin be torn apart by the fierce life force within her as she twisted wildly.

"Girl, hang in there!"

Lu Chen roared in a deep voice. He directly activated the Supreme Blood Furnace deep within his chest, its rumbling echoing throughout the stone chamber. He forcibly reversed his cultivation technique, reducing his extremely violent and high-temperature black blood energy to the lowest possible temperature.

A large amount of pure, dark black blood flowed continuously into A-Nan's thin, frail back through her large palms.

The accumulated qi and blood of ten thousand jin transformed into an impenetrable net, spreading directly within A'Nan's body. Lu Chen forcefully used his own reserves to share the destructive pressure brought by the fourth-tier divine blood. The rampaging and chaotic medicinal power crashed headlong into this net of condensed dark qi and blood, and was immediately contained and forcibly organized.

With the pure blood and qi filtered through Lu Chenxuan's black membrane guiding it, the originally rampant dragon blood finally yielded. The raging life force became as docile as a stream under the clash of the two forces, no longer rushing about recklessly.

Inch by inch, this immense power of creation seeped deep into A-Nan's bones and marrow, which radiated a faint jade-like light.

After absorbing this power, the jade bones' surface luster deepened, and the texture of the bones underwent a dramatic transformation. The energy conversion process was extremely dangerous, yet it also revealed the profound mystery of reshaping life.

A full half hour passed.

The extremely dangerous, potentially ruptured red glow on A-Nan's body completely faded away. The radiance of her transformed jade bones also receded into the deepest recesses of her body, and her tense, twitching little body finally softened.

This life-risking, intensive absorption has finally achieved a stage of success. The little girl's foundation is beginning to take shape, and the anxiety that had been hanging in the air can finally be put down.

Lu Chen let out a long breath of hot air, and his tense nerves relaxed.

He had just removed his sweaty hands from the little girl, and hadn't even had a chance to wipe them off yet.

"Crack!"

A piercingly sharp cracking sound, like a hard object shattering, suddenly erupted in the stone chamber.

Lu Chen looked down and saw that A'Nan's little hands, which had been gripping the edge of the stone bed so tightly from the intense pain, had broken off a large chunk of that rugged blue rock. That was a piece of underground raw stone with a hardness comparable to refined iron.

Seeing this turn of events, Lu Chen was not shocked or angry; instead, he burst into laughter.

He reached into the tattered animal-hide bundle at his waist and casually pulled out a fragment of a captured fine steel flying sword. With a clang, he tossed the fragment of the cultivator's magical artifact to A'Nan's side.

"Girl, don't touch that broken rock. Try squeezing this piece of scrap metal and see how strong you are!"

Lu Chen laughed and encouraged her, completely following the typical approach of a rough and tough man leading a tough kid, ignoring any talk of gradual progress and directly guiding her to adapt to this domineering power belonging to the extreme path.

A-Nan sat up in a daze, and with her chubby little white hand, she grabbed the piece of refined steel. She didn't even frown, and just instinctively squeezed and twisted it.

"Garara..."

The indestructible broken sword, originally imbued with immortal essence, was twisted into a pretzel by Anan's two fingers. Scrap metal fell to the ground in a flurry.

Anan dropped the twisted lump of iron in her hand, tilted her little head, and spoke in a childish voice.

"Lu Chen, even the iron from the celestial beings isn't as hard as the black cornbread from our Xuanni City."

The soft, gentle tone, coupled with the terrifying strength with which she effortlessly kneaded refined steel, created an extremely stark contrast. With the most innocent and endearing voice, she delivered a resounding slap to those self-righteous cultivators.

The joke had barely ended.

A-Nan raised her little hand and touched the blood-jade eye-covering garment tied to her forehead. The little girl paused, then pointed her delicate white finger directly to the southwest corner of the stone chamber's ceiling.

"The land sank!"

"There... there's a red line. That's the True Essence Death Line, flashing wildly, very brightly."

Those ancient, true-vision spiritual eyes, having undergone a transformation, directly unleashed their new ability to see through illusions, instantly passing through the stone cover and keenly capturing the Soul-Chasing Mark hidden deep within the crevice.

The rugged smile on Lu Chen's face vanished instantly, replaced by a chilling killing intent that was suffocating.

With a sudden burst of power, his massive feet slammed into the ground, lifting his dark, fleshy frame straight up. The tendons in his right arm bulged, and he unleashed a relentless, all-out straight punch, aiming a devastating blow at the stone slab in the corner!

"boom!"

The heavy rocks, along with the rock wall behind them, crumbled into dust on the spot.

A deeply concealed crimson soul-tracing talisman, under the direct crushing force of Lu Chen's pure yang energy, didn't even have time to emit a glimmer of spiritual light before being instantly blasted into dust. The scheme of the fat pavilion master of the Myriad Treasures Spirit Pavilion, who had secretly plotted to use someone else to kill, was completely exposed.

Lu Chen landed again, his heavy iron boots creaking on the gravel. He turned his head, suppressing his anger as he questioned him.

"Girl, look at the situation outside!"

Anan gripped the edge of the stone bed with her two small hands, her gaze piercing through the blood-jade eye-covering garment and through the 100,000-jin black stele sealing the door in front of her, looking timidly outside.

"Outside……"

"That immortal has laid down many white nets, all made of true essence. Those nets are closing in." The little girl swallowed hard. "In ten more heartbeats, that huge net will engulf us."

The villains weren't idle at all. During the half-hour of refining the medicinal power, they were constantly grinding away the natural, spiritually impenetrable magnetic field barrier of the stone chamber with their water-milling technique. The deadly trap was about to close.

Ah Nan had just finished speaking.

An extreme backlash suddenly struck!

Forcibly deciphering the array's core and seeing through the closing trajectory of the Death Gate directly exhausted Anan's already limited mental energy. Using supernatural powers beyond one's level inevitably incurs extreme physical punishment.

Two lines of shocking bright red blood flowed down the blood-red jade eye-covering garment, instantly staining half of the little girl's pale cheeks.

"Well……"

Anan instantly became extremely weak, her small body completely devoid of strength. She curled up into a small ball in pain and threw herself into Lu Chen's broad arms, shivering from the cold.

Lu Chen lowered his head and looked at the two glaring bloodstains.

The savage killing intent that had been suppressed in his eyes for so long surged to its limit at this moment! This terrible battle damage completely ignited the powder keg of his protective instincts.

He didn't utter a word, but his movements were incredibly fast. He drew out the incredibly sturdy bowstring of the demonic python, held Anan protectively in his arms, and tightly wrapped it around her chest and abdomen. Each knot was tied so tightly it cut into her flesh, ensuring the little girl would not be jolted at all.

Lu Chen suddenly raised his head, his eyes turning completely bloodshot, and a terrifying roar like that of a raging bear erupted from his chest.

"How dare you hurt my girl!"

"Today I'm going to grind every single bone in your body into dust!"

At this moment, outside the underground stone chamber.

The branch leader of the Azure Sky Sword Sect's Eastern Xuan branch was hovering in the air, a savage grin on his face. He suddenly pressed down with his large hand, issuing commands to the hundred elite sword cultivators who were arrayed around him.

"Seal off the last gap in the formation for me!"

"Today we'll trap this demon in a barrel and refine this country bumpkin into a deadly formation!"

Inside the stone gate, the prelude to the rampage had already begun.

With a single tug, Lu Chen gripped the thick, century-old black iron chain tightly in his palm with a clang.

The extreme blood furnace in his chest spun wildly, emitting a ferocious roar that could shatter internal organs; the sound of blood flowing was even louder than the incantations being cast by the immortal sword cultivators outside. The 100,000-jin savage embryo had completely revived.

Seize the last five breaths before the death formation closes in.

With a burst of power from his feet, Lu Chen, the tyrant of the lower lands who was completely enraged, charged outwards with the fierce monument weighing 100,000 jin, as if forcibly smashing through all the gates of death!
