23: Chapter 23 Earth Vein Cave, Twin Flames Resonate

Inside the rock crevice, the air seemed to freeze.

Xiao Yi Xian curled up on the ground, her body trembling uncontrollably. Grayish-black poison gas, like an unbridled miasma, seeped continuously from her nose, mouth, and skin. The grayish-white poison lines writhed and bulged frantically beneath her fair skin like venomous serpents waiting to devour someone, their color gradually deepening into a dark purple. Her hands clawed desperately at the ground, leaving deep gouges with her nails. Her face was a mask of intense agony mixed with a desperate struggle to maintain consciousness, and suppressed, beast-like whimpers escaped her throat.

Forcibly using her source poison blood was like throwing a massive boulder into an already overflowing lake of poison, completely shattering the fragile balance that had just been established. The backlash of the Calamity Poison Body was far more violent than any time before!

"Xiao Yi Xian!" Lin Yan rushed to her side, ignoring the dull pain from the burning mark on his back and the Magma Earth-Walking Dragon that might be pursuing them from afar. He could feel the poison power in Xiao Yi Xian's body running completely wild. It was not only eroding her meridians and internal organs, but a cold, violent aura was also assaulting her soul and consciousness. If left unchecked, she would at best lose her entire cultivation and suffer mental damage, and at worst, her poison body would completely erupt, liquefying her into a pool of poison on the spot!

"Living Spirit Flame! I must increase the intensity!" Without hesitation, Lin Yan once again catalyzed that tiny emerald spark in his dantian. This time, the Living Spirit Flame energy he extracted was slightly thicker than before, carrying a denser breath of life as he attempted to force it into Xiao Yi Xian's body to suppress the rampaging poison power.

However, the moment the Living Spirit Flame's energy entered this time, it met with unprecedentedly fierce resistance! The out-of-control poison power seemed to possess a will of its own—cold, violent, and highly corrosive. It frantically clashed with and tore at the emerald life energy, even attempting to contaminate and assimilate this foreign life force in turn! The two diametrically opposed energies locked in an even more brutal tug-of-war inside Xiao Yi Xian's body, causing her agony to multiply exponentially!

"Ah—!" Unable to hold it in any longer, Xiao Yi Xian let out a shrill scream. Her body convulsed violently, and dark purple poison blood began to seep from her seven facial orifices!

"This won't work! Her poison body's source has been completely triggered. The Living Spirit Flame has the opposite energy property. Forcing a suppression will only intensify the conflict and accelerate her body's collapse!" Lin Yan was horrified. He quickly withdrew most of the Living Spirit Flame's energy, leaving only an extremely faint trace to protect Xiao Yi Xian's heart meridians and soul source, preventing her consciousness from being completely consumed by the poison power.

What should I do? Conventional methods are useless! System! Lin Yan cried out in his heart.

[Detected a full-scale riot of the target 'Xiao Yi Xian's' Calamity Poison Body source. Conventional life energy neutralization plan failed.]

[Emergency plan deduction in progress... Retrieving host's available resources...]

[Option One: Use the 'Seed Flame of Void Devouring Flame' to attempt to devour a portion of the rampaging poison source. Risk: Extremely high! Although the Void Swallowing Flame can devour all things, the Calamity Poison Body's source has a special nature and is bound to the target's soul. Forcible devouring may lead to damage to the target's soul or worsen the out-of-control poison. Success rate: Less than twenty percent.]

[Option Two: Find an extremely yin or extremely cold environment/energy to fight poison with poison, temporarily freezing/suppressing the rampaging poison power to buy time. Success rate: Depends on the grade of the environment/energy.]

[Option Three: Burn the poison power with a special flame to attempt refining and purification, guiding it to transform in a controllable direction (requires extremely high flame control and a deep understanding of the nature of poison power). Risk: Tremendous, requires the host's own flame control to reach the micro-realm, and requires extreme cooperation from the target. Success rate: Less than ten percent.]

All three options were riskier than the last, with pitifully low success rates. However, Xiao Yi Xian's situation was critical. Her aura was weakening rapidly, and the poison lines beneath her skin were growing darker and darker, as if they would completely explode at any moment!

Right at this moment, the deep, dark "Seed Flame of Void Devouring Flame" inside Lin Yan's body, along with the emerald "seed flame of the Living Spirit Flame" beside it, seemed to sense something simultaneously. Both transmitted an even clearer desire and restlessness, pointing toward the dark tunnel entrance that had suddenly appeared deep within the rock crevice!

The attraction coming from that tunnel was not only directed at the Heavenly Flames, but it also seemed to... exert a faint, strange pull on that rampaging Calamity poison energy?

"The tunnel... the energy inside..." A flash of inspiration hit Lin Yan's mind! System Option Two mentioned needing an extremely yin or extremely cold environment/energy to fight poison with poison! Why would an attraction to Heavenly Flames (especially the Void Swallowing Flame, which represented devouring and nothingness) come from the depths of this Lava Cave? Unless... there existed something extremely special there, perhaps even sharing the same origin as or opposing the Heavenly Flames, capable of balancing extreme energies!

Combining the System's previous prompt that the "Lava Cave" might contain an "abnormal fire-attribute energy reaction," along with the rumors of the poison master Yao Ling drawing a fake map... a bold conjecture surfaced in Lin Yan's mind.

"Let's gamble!" Determination flashed in Lin Yan's eyes. He scooped up Xiao Yi Xian, whose consciousness was already blurred, her body burning hot (from the poison erosion) yet icy cold (from her fading life force), and charged without hesitation toward the rippling stone wall passage!

The moment his figure vanished into the ripples, a strange suction force pulled at him, and the light and shadows before his eyes shifted. The expected scorching heat did not appear. Instead, a warm, heavy energy carrying an ancient, vast aura enveloped his entire body.

Passing through a short, downward-sloping corridor that could only accommodate two people side-by-side, his vision suddenly opened up.

This was a massive underground cavern that, while naturally formed, bore unmistakable traces of manual modification. Countless translucent stalactites hung from the cavern ceiling, emitting a soft, milky-white fluorescence that illuminated the interior. In the center of the cavern was a circular pool about ten Zhang in diameter. However, the pool did not contain clear water, but a strange liquid shrouded in a mist of interwoven pale blue and crimson light. The glowing mist rotated slowly, forming a delicate balance. On the ground around the pool, complex and ancient patterns were engraved, faintly forming a massive array. Dim crystals that had run out of energy were embedded at the array's nodes.

Most eye-catching of all, suspended in the center of the pool was a half-man-tall, irregularly shaped dark-gold crystal. Inside the crystal, a small cluster of shifting flame phantoms seemed to be sealed, sometimes taking the shape of a green lotus, sometimes a milky-white pure lotus, and sometimes turning into a pitch-black vortex... It actually resonated faintly with the several Heavenly Flame seed flames inside Lin Yan's body! And the aura emitted by the crystal was gentle, upright, grand, and majestic, as if it could accommodate and harmonize all violent energies.

"An earth core fire marrow crystal! And... it's an ancient fire marrow crystal that has nurtured multiple embryonic forms of Heavenly Flames or retains the Dao marks of multiple Heavenly Flames!" Lin Yan's heart shook violently. This was a natural treasure countless times more precious than an earth heart fire lotus! It was not a Heavenly Flame itself, but the condensed core essence of a place where Heavenly Flames were born or nurtured over a long period. It contained the most primordial, upright, and peaceful fire-attribute energy, and even carried a trace of the aura of natural creation, possessing a nurturing and harmonizing effect on energy of any attribute!

No wonder the Void Swallowing Flame and the Living Spirit Flame were so eager! To the Void Swallowing Flame, the various Heavenly Flame Dao marks contained within this fire marrow crystal were excellent "food" and "simulation templates"; to the Living Spirit Flame, the trace of creative life force within was an immense supplement!

Even more crucially, the gentle, neutralizing aura emitted by this fire marrow crystal, along with the energy field in the pool where the pale blue (suspected to be extremely cold earth vein essence) and the crimson (earth fire essence) interwoven, formed a perfect, natural, and powerful energy balance field! Wasn't this the ideal environment to suppress and guide Xiao Yi Xian's rampaging poison power?

Heaven never seals off all exits!

Lin Yan hesitated no longer. Carrying Xiao Yi Xian, he quickly walked to the edge of the pool. He did not dare to rashly enter that strange pool water, but instead gently placed Xiao Yi Xian at a node of the array patterns by the pool. This spot was most directly affected by the energy fields of the fire marrow crystal and the bi-colored pool.

The moment Xiao Yi Xian touched the ground, the grayish-black poison gas spilling uncontrollably around her body seemed to hit an invisible barrier, and its diffusion speed instantly slowed down. The rampaging poison power inside her body also seemed to be attracted and suppressed by that gentle, neutralizing aura, slightly dampening its frantic, surging momentum.

"Xiao Yi Xian! Listen to me!" Lin Yan grasped her cold hand, his voice deep and powerful, carrying an unquestionable firmness. "This is the earth vein's energy balance point, which can temporarily suppress your poison power! I am going to try and guide the energy here, coordinating with the techniques of the poison manual in your body, to reorganize and control the poison power! The process will be very painful, but this is our only chance! Trust me, and trust yourself! Guard your mind, and follow my guidance!"

Perhaps having heard Lin Yan's voice, or perhaps pacified by the special energy field of this place, Xiao Yi Xian's unfocused eyes barely managed to gather a faint glimmer of light. Summoning her last ounce of strength, she gave an extremely slight nod.

Lin Yan took a deep breath and sat cross-legged opposite Xiao Yi Xian. He extended his hands, gently placing one against Xiao Yi Xian's forehead (the upper dantian, where the soul resides) and the other against her lower abdomen (the lower dantian, where the poison power source gathered).

He first channeled the most refined life energy of that "seed flame of the Living Spirit Flame," turning it into a trickling stream that slowly flowed into the space between Xiao Yi Xian's brows. This protected her soul source, which was on the verge of collapsing from the poison erosion, acting like a candle in the wind to sustain her final trace of clarity.

At the same time, he attempted to connect his own soul perception with Xiao Yi Xian's soul (an extremely risky action where the slightest slip could result in soul damage), transmitting his resolute will and will to survive: "Hold on! Circulate the poison manual!"

Receiving this support, Xiao Yi Xian's remaining consciousness grabbed onto it like a lifeline. Relying on instinct and her last shred of willpower, she began to painstakingly circulate the basic techniques of the Seven-Colored Poison Manual.

Next, Lin Yan sank the majority of his mind into the special energy field of this Earth Vein Secret Grotto. Carefully mobilizing his Dou Qi, he channeled the pale blue and crimson interwoven mist hovering above the pool, guiding it thread by thread into Xiao Yi Xian's body in an extremely gentle manner.

The pale blue, extremely cold energy, like frost, began to permeate from the outside, freezing the most violent and overflowing poison power. This temporarily deactivated it, slowing down the destruction of Xiao Yi Xian's body.

Under Lin Yan's precise control (leveraging the affinity of the Green Lotus Core Flame seed flame), the crimson earth fire energy slowly seeped into Xiao Yi Xian's meridians, coming into contact with the relatively "milder" poison power that had been initially guided by the Seven-Colored Poison Manual's techniques. The scorching heat of the earth fire energy and the icy coldness of the poison power should have clashed, but under the mediation of this location's special energy field and the neutralizing aura of the fire marrow crystal, they actually produced a strange "calcining" and "refining" effect! Like forging iron, with the earth fire as the furnace and the poison power as the iron, the violent and chaotic parts of the poison power were scorched and stripped away bit by bit, forcing the remaining portion to become more condensed and controllable!

This was an extremely delicate, complex, and painful process. Xiao Yi Xian's body became a battlefield and a melting pot where ice and heat alternated, and stripping and condensing occurred in tandem. She had long since lost her voice from the pain, only able to convulse unconsciously as sweat mixed with poison blood, soaking the ancient patterns beneath her. Yet her remaining consciousness held fast to the thread of conviction transmitted by Lin Yan, cooperating with the poison manual's techniques like a lone boat in a tempest, tenaciously holding on.

Lin Yan was also under immense pressure. He needed to simultaneously control the Living Spirit Flame to guard her soul, guide the bi-colored energy to refine the poison power, maintain the fragile connection between his own soul and Xiao Yi Xian's, and remain on guard against unknown risks in this place and the "Heart-Burning Seal" left by the Magma Earth-Walking Dragon on his back. His face was as pale as paper, sweat dripped from his chin, and his soul power was draining like an opened sluice gate.

Time lost its meaning here.

Before long, the frantically rampaging poison power inside Xiao Yi Xian's body, under the suppression of the earth vein's energy field and the "refining" guided by Lin Yan, finally began to calm down. The grayish-black poison gas stopped spilling out in large amounts, and the dark purple poison lines dancing wildly beneath her skin began to fade and slowly gather together, starting to flow slowly and orderly along the specific pathways recorded in the Seven-Colored Poison Manual. Although still powerful and dangerous, it was at least restrained within a controllable range once again.

The heart-palpitating, violent aura on her body gradually dissipated, and her breathing went from weak and intermittent to steady and long. Although it still carried the unique coldness of poison power, it was no longer chaotic.

It was a success!

Lin Yan let out a long breath of turbid air mixed with the taste of blood, slowly withdrawing his hands and soul connection. He felt the world spinning around him as his vision went dark, nearly causing him to collapse. The double overdraw of his soul and Dou Qi left him extremely weak at this moment.

He forced himself to look at Xiao Yi Xian. She was still unconscious, but her face was no longer a deathly gray. Though her brow was still furrowed, she looked much more peaceful, indicating that the most dangerous moment had passed.

Lin Yan also quickly swallowed his last two improved energy accumulation pills and sat cross-legged to regulate his breathing, while warily observing his surroundings. His gaze involuntarily drifted back to the "earth core fire marrow crystal" in the center of the pool, which was emitting enticing fluctuations.

Right at this moment, the System's prompt, which had been silent for a long time, rang out with an unusual fluctuation:

[Warning: The 'Heart-Burning Seal' on the host's back has become abnormally active! The seal is absorbing the trace fire marrow crystal energy permeating this area to self-strengthen and improve its positioning accuracy! It is estimated that in one to two hours, the seal's fluctuations will reach their peak, allowing the caster (Magma Earth-Walking Dragon) to clearly lock onto your current location!]

[At the same time, it is detected that the 'Void Swallowing Flame Dao mark' sealed inside the earth core fire marrow crystal has generated a strong resonance with the Seed Flame of Void Devouring Flame inside the host's body! The seed flame's activity has increased significantly, strengthening its devouring and simulation instincts. Do you wish to attempt to guide the seed flame to absorb the relevant Dao marks from the fire marrow crystal to enhance the seed flame's source? Note: This process may trigger energy fluctuations and intensify the activity of the 'Heart-Burning Seal'.]
