Yin-Yang Profound Dragon Pill

Sacred Pill City, Inner Domain.

"Kid, hurry up! Show me that technique you demonstrated during the test again!"

Han Shanshan shot over like a bolt of black lightning. The moment she landed, she impatiently shouted at Yao Chen, her beautiful phoenix eyes blazing with undisguised urgency.

"Senior..."

"I know, there's no such thing as a free lunch." Han Shanshan waved her hand and briskly cut Yao Chen off. With a flick of her wrist, a jade slip appeared in her hand with a swish.

She waved the combat skill manual before Yao Chen and said in a domineering tone that brooked no refusal, "Here, I'll trade you this for it. How about it?"

Yao Chen blinked, his gaze falling on the combat skill manual as his heart stirred slightly.

Though this Martial Uncle Han acted strangely and domineeringly, she was quite generous. Right from the start, she had offered a combat skill of no low grade.

He opened his mouth, trying to explain things clearly. "That works, but, Senior, actually..."

"Ugh, this is so annoying!"

The woman in black had clearly run out of patience. She tore off the loose black robe draped around her body, and with a rustle, the black fabric fell to the floor like drifting clouds.

Lin Yu felt his vision suddenly brighten, as though the entire alchemy chamber had become several shades brighter in that instant.

"Stop calling me Senior. I'm only at most ten years older than you." Han Shanshan casually tossed the black robe aside and planted her hands on her hips.

"Mm, call me Sister. I'll look after you from now on. You want to enter the Pill Tower to study alchemy, right? That might be difficult, but it's fine. Sister can teach you just the same. Hmph, those old fossils have asked me to lecture before, and I couldn't even be bothered to go."

Yao Chen gave a wry smile and shook his head, finally finding the chance to finish what he wanted to say. "That technique isn't worth anything at all. My big brother knows it too. Let him demonstrate it for you."

He had figured it out. This Martial Uncle Han was a complete alchemy fanatic. If he did not explain the ins and outs of that technique today, she definitely would not let him go.

"My big brother?" Han Shanshan finally shifted her gaze from Yao Chen to Lin Yu, who had remained silent at the side.

She looked him up and down, then suddenly recalled what Yao Chen had said in the hall earlier—"My big brother can test for the seventh grade."

"I know this technique too." Han Shanshan withdrew her scrutinizing gaze, then changed the subject. "But when you use it, it seems a little different. Fine, demonstrate yours for me too, and then we can discuss it."

As she spoke, she decisively tossed the combat skill manual in her hand to Yao Chen.

Then, she took an alchemy cauldron from her Storage Ring and steadily placed it in the center of the alchemy chamber.

The cauldron was entirely dark jade in color, its body engraved with exquisite flame patterns. At a glance, it was clearly no ordinary item.

Seeing Yao Chen shove the job onto him just because he found it troublesome, Lin Yu did not hesitate either.

He stepped forward and stood before the dark jade cauldron. Closing his eyes slightly to focus, he then flicked a finger.

A strand of Multicolored Beastfire flew from his fingertip. Like a nimble little fish, it darted into the cauldron in an instant.

The flame patterns on the cauldron lit up one after another, spreading from its legs to its mouth. In that moment, the entire cauldron seemed to come alive, emitting a gentle yet profound aura.

A trace of surprise flashed through Lin Yu's eyes.

This alchemy cauldron seemed to contain some special property. Activated by the Beastfire, it resonated with his flames in some way, greatly increasing both the precision of his fire control and the temperature of his flames.

Han Shanshan's beautiful eyes immediately brightened.

For an alchemist, aside from the alchemy cauldron, flames were also an indispensable key factor.

With the dual support of this cauldron and the Beastfire, Lin Yu felt that he could even attempt some pills that had previously been beyond his ability.

For example—

A high-grade seventh-grade pill.

Once that thought arose, he could no longer suppress it.

Without further hesitation, he swept a hand over his Storage Ring. Dozens of rare medicinal ingredients flew out in succession, arranging themselves by category before him.

At the same time, he released his aura without holding anything back.

The Dou Qi of an Eight-Star Dou King surged out like a raging tide, stirring an invisible wave of air through the alchemy chamber.

The soul power of Mortal Realm Great Perfection spread out, precisely bringing every trace of medicinal potency in every herb into his perception.

Han Shanshan's pupils narrowed slightly.

An Eight-Star Dou King's cultivation was nothing much in her eyes, but paired with soul power at the Mortal Realm Peak, along with that exquisite fire-control technique from earlier, this young man truly was qualified to test for the seventh grade.

What Yao Chen had said in the hall earlier was probably not bragging.

Lin Yu ignored Han Shanshan's gaze. He had already completely immersed himself in the state of alchemy.

His hands fluttered like butterflies among flowers as he tossed herb after herb into the alchemy cauldron. Wrapped in the Multicolored Beastfire, they were swiftly purified and refined.

His methods combined the strengths of many schools: the orthodox techniques from the Sixth-Grade Alchemist inheritance purchased from the Fusion Panel shop, the Yao Clan techniques Yao Chen had taught him during their discussions, the many practical methods he had exchanged with Dan Huchen over the past three years, and his own insights accumulated over the years.

He had recorded these methods and techniques from different schools onto jade slips, then placed them into the Fusion Panel for fusion. In the end, they formed a system of alchemy unique to him.

The pill he intended to refine this time was called the Yin-Yang Profound Dragon Pill.

Back on Demon Valley Peak, when Lin Yu and Yao Chen had discussed alchemy, they had deduced a pill formula capable of allowing someone to break down and rise anew.

The Yin-Yang Profound Dragon Pill had originally been created by Yao Chen in the future, but with Lin Yu's involvement this time, the two had inspired one another, and this pill formula had unexpectedly been developed far earlier than in the original timeline.

Time passed second by second. Fine beads of sweat gradually formed on Lin Yu's forehead, yet his eyes remained clear and his movements as steady as ever.

He pushed the soul power of Mortal Realm Great Perfection to its limit. Every wisp of flame's temperature, every drop of medicinal liquid's fusion, and every pill pattern's inscription appeared in perfect detail within his soul perception.

Han Shanshan stood quietly at the side watching. From curiosity at first, to later surprise, and now solemnity, the changes in her expression perfectly reflected her reassessment of Lin Yu's alchemy skill.

Her gaze closely followed Lin Yu's every movement, while her lips moved slightly as though she were silently deducing something.

After an unknown amount of time, a low rumble suddenly came from the sky above the alchemy chamber.

At first, the sound was distant and faint, but it quickly became clear and dense.

Pill lightning!

What Lin Yu was refining was no ordinary seventh-grade pill, but a high-grade seventh-grade pill!
