The younger sister's soul was shared, and the older sister became numb.

High above in the sky, biting gale winds whistled past.

Lin Yuan's figure and appearance changed rapidly amidst the swirling spirit light.

His bones emitted faint crisp sounds, and his facial contours changed accordingly.

In just a moment, he transformed from a handsome youth in his twenties into a middle-aged man who looked to be in his thirties, with stern features and steady eyes.

The light feather boat traced an arc in the air and landed silently on a rarely visited cliff halfway up the mountain.

The cliff extended outward into a huge, flat platform.

In the center of the platform, a huge pool gathered mountain spring water. The water was clear and surged out endlessly, flowing to the edge of the cliff to become a magnificent waterfall that plummeted down, smashing into a deep pool and kicking up thousands of water mists.

This place was excellent; one could attack when advancing and defend when retreating.

Lin Yuan stood by the waterfall with his hands behind his back, waiting quietly.

About half an hour later, a faint sound of breaking air came from the horizon.

A beautiful figure arrived on a flying sword and landed nimbly not far from the platform; it was none other than Mu Wanqing.

"Greetings, Fellow Daoist Mu." Lin Yuan cupped his fists, his voice disguised to sound calm and steady.

Mu Wanqing's beautiful eyes swept up and down over Lin Yuan, a hint of surprise flashing deep within her pupils.

She had imagined countless times that an alchemist capable of refining a soul nurturing pill must be an old, white-haired master of Alchemy from some Sect.

Yet, she had never expected the other party to be a rather handsome and stern-looking man.

Although cultivators should not be constrained by appearances, for the sake of the soul nurturing pill, she had long been prepared to pay any price.

But if the person she was cooperating with was easy on the eyes, it was ultimately a good thing.

"You are Huang Feihong, Fellow Daoist Huang, introduced by Fellow Daoist Sun?" Mu Wanqing spoke, her voice crisp, carrying the efficiency and caution of a merchant.

"Correct, that is I." Lin Yuan nodded.

"Fellow Daoist Sun said in the voice transmission talisman that you are a Sixth-Grade Alchemist," Mu Wanqing's gaze became sharp, "but for a Sixth-Grade Alchemist, the difficulty of successfully refining a soul nurturing pill is still quite high."

"I only have one yang returning lotus seed. Furthermore... the refining of this pill requires me to act as the pill catalyst. If it fails, I will suffer heavy losses."

"Therefore, I would like to ask Fellow Daoist Huang to prove yourself. Of course, if you succeed, the reward will certainly be generous."

The other party's caution was completely within Lin Yuan's expectations.

If it were him, he would only be even more cautious than her.

"Self-proof is certainly possible," Lin Yuan's gaze met hers without flinching, "however, the reward must be agreed upon beforehand."

"One hundred thousand Spirit Stones." Mu Wanqing directly quoted an astonishing price.

"Fellow Daoist Mu is straightforward, so I shall prove myself."

Lin Yuan pondered for a moment, then flattened his palm and flipped it upward.

Three round Medicinal Pills, surrounded by spirit light, lay quietly in his palm.

A rich, thick medicinal fragrance instantly dispersed.

Mu Wanqing's pupils suddenly contracted.

As the Pavilion Master of the Pill Treasure Pavilion, she still had the discernment to recognize them at a glance.

High Grade nirvana pill!

Moreover, the quality, luster, and medicinal fragrance of the three Medicinal Pills were almost identical, and there was still a faint trace of heat remaining on the pill bodies, clearly having just been taken out of the furnace.

This meant that the person before her had reached a point of Perfection in Alchemy!

"These three Medicinal Pills were refined by me not long ago." Lin Yuan's voice was calm, carrying confidence.

"Although the difficulty of refining a nirvana pill is not as high as a soul nurturing pill, it still requires a Sixth-Grade Alchemist to undertake it. As long as Fellow Daoist Mu is willing to act as the pill catalyst, and I use my Secret Technique, the success rate will definitely not be low."

Mu Wanqing's heart beat violently in her chest, but she still forcibly suppressed the surging excitement and asked: "Does acting as a pill catalyst cause harm to me? For instance, regression in Cultivation, or damage to my Foundation..."

Lin Yuan shook his head: "You can rest assured about that; not only is it harmless, but it even... has some minor benefits."

Upon hearing this, the last heavy stone in Mu Wanqing's heart finally fell.

"Since that is the case, please follow me back to my residence, and we shall begin immediately."

Lin Yuan, however, shook his head again.

"Let's do it here."

His gaze swept across this empty cliff, "This place is usually undisturbed and quiet. Moreover, this waterfall is flowing, full of water vapor, which is a place of extreme Yin, while the earth beneath our feet is heavy, acting as the Foundation of extreme Yang. Using heaven and earth as the furnace and Yin and Yang as the charcoal, it is an excellent place for Alchemy. If any accidents occur during the refining process, the two of us can also retreat quickly."

Go to her residence? In case the other party set up a net to capture him, this High Grade alchemist, wouldn't that be walking right into a trap? One should not have the intention to harm others, but one must have the heart to guard against others.

"Right... right here?"

Mu Wanqing's gaze subconsciously swept over the open-air environment, and a moving blush quickly appeared on her pretty face.

She was intelligent, and instantly understood the deeper meaning in Lin Yuan's words.

She bit her lower lip tightly, her inner self at war. She had kept herself pure for many years; how could she have ever thought that she would engage in such shameful acts with a man she met for the first time in such a desolate wilderness.

But once she thought of her sister's increasingly weakening Divine Soul, all shame and hesitation were instantly replaced by a sense of determination.

Lin Yuan's mouth curved into a playful arc. He saw the other party's hesitation and continued to increase the pressure, "Fellow Daoist Mu, you and I cultivating to become immortals is inherently a Heaven-Defying act, stealing the fortunes of heaven and earth. How can one achieve the great Dao by being constrained by minor details? You wouldn't... still be a virgin, would you?"

Provoked by Lin Yuan's such blunt and brazen words, Mu Wanqing's cheeks were so red they were almost dripping blood. She stomped her foot hard, as if she had made a certain decision.

"Since that is the case, then let's do it here!"

"Fellow Daoist Mu, please."

...

The waterfall poured down like the Milky Way, and the huge roaring sound resounded through the valley, covering up all faint noises.

Inside the Pill Treasure Pavilion.

Qing Tan, who was counting Medicinal Pills, suddenly stiffened.

A domineering and scorching vital essence of life surged violently from the depths of her Soul without warning!

On her fair, pretty face, two strange flushes appeared pathologically, her heartbeat accelerated uncontrollably, and her breathing became rapid.

This feeling...

She and Mu Wanqing shared a twin Soul, their hearts connected, and they had a perception of each other's emotions and physical conditions that exceeded that of ordinary people.

This dead girl Mu Wanqing... what is she doing?

Qing Tan's cheeks were burning hot; how could she not know what her good sister was experiencing?

That constantly surging, both unfamiliar and magnificent, masculine breath made her whole body go limp, almost unable to stand steady.

But... she didn't have a Dao Companion, did she?

"Sigh... forget it, forget it, she is at this age already, this kind of thing..." Qing Tan sighed helplessly in her heart.

She had originally thought that this sudden strange feeling would pass quickly.

But what made her almost break down was that this feeling was like a tide, wave after wave, continuous and endless, each time more violent than the last.

It lasted for a full half-day before the strange feeling that made her restless slowly dissipated.

At the edge of the waterfall, Lin Yuan was panting heavily.

In his eyes, the familiar small golden characters quietly refreshed.

【Cultivation: Foundation Establishment Early Stage: 0 / 10000 (addable points)】

【Fourth-Grade Alchemist: 0 / 600 (addable points); Sixth-Grade Artifact Refiner: 0 / 400 (addable points)】

【Fourth-Level Fire Control Art: 0 / 400; Illusion Transformation Art (Perfection)】

【Available attribute points: 850】

【Special attribute points: 1】

Mu Wanqing was at the Foundation Establishment Mid Stage; one Dual Cultivation session could provide him with forty attribute points.

Just now, he had "brushed" it a full three times.

One hundred and twenty attribute points, obtained.

"Fellow Daoist Huang, please... please help me refine the pill!"

Mu Wanqing's voice carried a hint of lazy trembling. The blush on her cheeks had not yet faded, and in her moist eyes, there was no sign of disgust, but rather a hint of exploration and curiosity, clearly indicating that the experience just now had far exceeded her expectations.

"Before refining the pill, may I ask, is this soul nurturing pill for you to take yourself?" Lin Yuan asked casually while regulating his breath.

"No." Mu Wanqing shook her head.

As she spoke, she took out a porcelain bottle from her Storage Pouch and handed it over.

Lin Yuan's eyes lit up quietly.
