The elixir was completed, and a radiant glow appeared, startling even the immortals!

Bang! The pill shattered, and wisps of blood-red mist erupted. Lin Yuan felt the mana inside his body vanishing rapidly!

"Awoo...!" The massive body of the Frost Bone Flood Dragon stiffened violently, twisting and rolling in mid-air in agony, as if its insides were enduring some unimaginable torture.

Its huge dragon tail lashed out wildly, smashing the surrounding stone walls, sending rocks flying and dust swirling everywhere.

It hissed in pain, its massive belly bulging out in an exaggerated arc like an inflated balloon, with blood-red cracks even visible spreading across its surface.

"Ughh—" Unable to endure it any longer, the Frost Bone Flood Dragon suddenly opened its maw, and after a bout of violent retching, spat out a clump wrapped in viscous liquid.

Immediately after, the aura on the Frost Bone Flood Dragon began to decline at a terrifying speed, like a punctured balloon.

The majestic pressure of the fifth-grade Yao Beast dissipated without a trace within a few short breaths.

Finally, its platinum-colored pupils lost their luster, and its massive body fell limply from mid-air.

Lin Yuan, who had been spat out, was in no better condition.

He was covered in foul-smelling mucus, his face was as pale as paper, and tearing pain radiated through his limbs and bones. His body was completely empty, and he couldn't even feel a trace of Spiritual Qi.

Lin Yuan struggled to move his body, leaning against a giant rock, gasping for breath heavily.

"Quick... act now!" He shouted hoarsely, using his last bit of strength.

Yue Qingyao snapped to attention.

Although her Spiritual Qi was also exhausted, her Lifebound Treasure, even without being fueled by mana, was far superior to ordinary Magical Artifacts in terms of material and sharpness.

She summoned it from afar, and the ancient-looking Flying Sword let out a clear sword chime as it landed in her hand.

At this moment, although the Frost Bone Flood Dragon's Physical Body remained, it had lost all Yao power to protect it, and its sturdy scales had a drastically reduced defensive capability.

"Puchi!" Yue Qingyao used all her remaining strength to swing the Flying Sword down.

That ferocious dragon head was severed at the root and rolled onto the ground.

Boiling hot dragon blood gushed out, staining a large area of the ground red.

Yue Qingyao forced herself to take out a palm-sized white Jade Bottle, murmuring incantations.

A faint ray of Spiritual Qi shot out from the bottle, enveloping the dragon head that still had its eyes open in death.

A moment later, a tiny, transparent mini-dragon, only an inch long, was forcibly ripped out from the head. It let out a silent shriek before finally being sucked into the Jade Bottle.

The fifth-grade dragon soul was obtained.

After finishing all this, Yue Qingyao could no longer hold on; her body went limp, and she slumped to the ground, gasping for air.

The cave finally returned to calm.

Having survived the disaster, the two of them remained silent for a while.

After a long time, Yue Qingyao looked at Lin Yuan: "This time... thanks to you."

Lin Yuan waved his hand. If he hadn't risked his life, he would be nothing but a pile of dry bones in the dragon's belly right now.

As time passed second by second, he finally gathered enough strength to cast a low-level Spell.

His fingertips moved slightly, and a Cleansing Spell barely formed.

A layer of faint light swept over his body like water ripples, and the foul-smelling, viscous liquid was instantly stripped away and purified.

The long-lost feeling of cleanliness returned, refreshing his spirit.

He did not stop, immediately taking a Medicinal Pill from his Storage Pouch and tossing it directly into his mouth.

The Medicinal Pill melted upon entering his mouth, and a gentle, warm current slid down his throat into his abdomen, then turned into a trickling stream, beginning to nourish his nearly exhausted Meridians.

A full two days passed before Lin Yuan recovered to his Peak state. He stood up and stretched his limbs, his joints making a series of cracking sounds.

Yue Qingyao was the same.

Only Su Qinghan remained pale, her aura weak and floating. Although most of the dragon poison had been dispersed, the residual poison had penetrated deep into her marrow, and it would likely be impossible to clear it completely without another five or six days.

"Now, help me with Alchemy." Yue Qingyao walked up to Lin Yuan and handed him a Jade Slip and a Storage Pouch.

Lin Yuan took the Storage Pouch, and when his Divine Sense probed inside, his heart jumped slightly.

Inside the pouch lay more than twenty types of Spirit Medicine, each exuding dense Spiritual Qi, clearly supreme grade items that had been carefully selected.

Several of them were over a hundred years old, emitting strong fluctuations of Spiritual Qi.

He pressed the Jade Slip against his forehead and sank his Divine Sense into it.

nirvana pill. Its name alone described the dominance and miraculous nature of this pill. Nirvana Rebirth.

This pill requires a unique technique to activate; as long as one still has a breath of life left, taking this pill allows one to survive in a desperate situation and reshape their vitality.

Even more terrifying is that during the process of healing, the user will undergo a Nirvana of breaking and then establishing; not only can they fully recover, but their Cultivation, bones, and even Divine Soul are likely to receive a huge advancement.

Lin Yuan's mind was deeply attracted by this Pill Formula. Unfortunately, the Jade Slip only recorded the method for Alchemy; as for the technique to exert the pill's efficacy, not a single word was mentioned.

He did not show any emotion, simply simulating the Pill Formula in his mind repeatedly until he was sure that every step and every detail was thoroughly understood, at which point he slowly opened his eyes.

Without a word, he flipped his hand and took out his own Pill Furnace. He sat cross-legged, his expression instantly becoming focused and solemn.

He first carefully plucked a petal from the yang returning lotus. The petal was crystal clear, as if condensed from light, and as soon as it left the plant, it emitted a refreshing, exotic fragrance.

Immediately after, he flicked his finger. Each auxiliary Spirit Medicine, following a specific order, turned into streaks of light and was precisely tossed into the Pill Furnace.

"Rise!" Lin Yuan let out a low shout, flipped his palm, and a wisp of deep blue flame appeared out of thin air—it was the Earth Core Nether Fire.

After advancing to the Fourth-Level Fire Control Art, his control over this strange fire had reached a Transcendent level.

The flame no longer danced violently, but acted like a living spirit snake, with every change in temperature under the precise control of his Divine Sense.

Beside him, Yue Qingyao's beautiful eyes were initially filled with anticipation, but soon, this anticipation turned into surprise, and finally, it transformed into shock.

As the proud daughter of the Misty Immortal Sect, she had certainly seen Sixth-Grade Alchemists before. She had also seen Sixth-Grade Alchemists from her Sect perform Alchemy.

But those Great Masters, compared to the Lin Yuan before her, actually seemed... somewhat rough.

The timing of each Spirit Medicine insertion was exactly at the most perfect node of the medicinal power's transformation within the furnace.

Every increase or decrease in heat was precise down to a hair's breadth, as if it wasn't him controlling the flame, but the flame actively cooperating with him.

The entire Alchemy process had not the slightest hesitation or signs of struggle.

Thinking back to Lin Yuan's ruthlessness and decisiveness when facing the fifth-grade Frost Bone Flood Dragon earlier, Yue Qingyao's gaze as she looked at him became increasingly satisfied.

Time passed quietly under the licking of the flames.

Suddenly, Lin Yuan's previously steady aura changed slightly, and his hand seals accelerated sharply, unleashing a series of dazzling hand signs.

"Open!" He opened his eyes abruptly and spat out a single word.

"Clang—" The lid of the Pill Furnace let out a clear hum and spun open on its own.

A brilliant, radiant light shot up from the furnace mouth, and immediately after, a dragon-eye-sized, perfectly round Medicinal Pill was guided by a gentle force and slowly flew out.

This nirvana pill was extremely special; when refining it, all the medicinal power from a full set of Materials needed to be condensed into one place, so only one pill could be obtained per furnace.

A rich fragrance of the pill instantly permeated the entire cave. The scent seemed to contain infinite vitality; just taking a whiff made one feel that their fatigue had dissipated significantly.

"It's done!"
