The Hehuan Sect cultivates alchemy; my senior sister helps me refine alchemy throughout the world.

Shen Yifei looked down at his crotch, then looked up at Gu Yunyan. When this woman said this, her eyes were fixed downwards, and her gaze was very precise.

"Master, the way you're talking makes it sound like my third leg is in your way."

"It won't bother me." Gu Yunyan sat back down in her chair and crossed her legs again. "But if you dare to lie to me, then it will bother me."

When Shen Yifei came out of the main hall, Song Hongliao was leaning against the door frame, her arms crossed, her ponytail hanging down behind her head. She looked him up and down as she saw him come out.

"How come you have three legs?"

Did you hear that?

"I'm not deaf." Song Hongliao turned around and walked forward. "Senior Sister's voice is so loud, half the mountain could hear it. You promised to refine a top-grade demon pill in three days? Are you crazy?"

"He's not crazy."

"You're only at the early Nascent Soul stage, and you've never even seen a Demon Core before. You refined a top-grade one in three days? Do you know how many spirit stones the Heavenly Mystery Pavilion has spent on top-grade Demon Cores over the years? They haven't bought a single one."

"That's because you haven't met me yet."

Song Hongliao stopped and looked back at him, her lips twitching slightly.

"You have a really thick skin."

"Those with thick skin get to eat their fill, those with thin skin don't get any."

Song Hongliao snorted and continued walking. After a few steps, she stopped again. "Luolu didn't go to help you today. She asked me to tell you that she didn't sleep well last night after going back."

"Why didn't you sleep well?"

"She said her lower abdomen felt hot, her whole body was burning up, and she couldn't sleep no matter how much she tossed and turned," Song Hongliao said, her eyes fixed on the ground. "I touched her forehead; it wasn't hot. But her body was definitely hot, like she had a fever."

Shen Yifei knew perfectly well that it was a normal reaction as the cold toxins were being expelled. But he gave a different explanation, "I cleared her meridians, which activated her yang energy, so of course she feels hot. This is a good thing; she'll be fine in a couple of days."

Song Hongliao nodded and continued walking. After a few steps, she stopped. "Are you refining pills again tonight?"

"Lian! Tell your two junior sisters that it will be the same as usual at midnight tonight."

"Green Ivy might not be able to come tonight; she said her back aches and she feels weak all over."

"That's perfect, you can control the fire."

"I won't."

"If you don't know, I'll teach you."

Song Hongliao stared at him for a couple of moments, then said, "Okay."

After saying that, she flicked her ponytail and left.

Shen Yifei returned to the stone house, and Liu Mengli floated out of the cauldron and sat cross-legged on the alchemy platform.

"Master, that woman Gu Yunyan is ruthless, three legs, tsk tsk tsk. Do you think if she really makes a move, she'll cut off the first two legs and keep the third one to play with later?"

"Can you please stop thinking about everything in that way?"

"Three legs, hahaha." Liu Mengli laughed and slapped her thigh. "Master, you're a three-legged toad now. Gu Yunyan wants to use you to practice her sword skills."

"Alright, alright." Shen Yifei sat down in front of the alchemy furnace and poured out the remaining medicinal herbs and demonic ore from yesterday from his storage ring. "To refine a top-grade alchemy in three days, I'll need the Myriad Things Cauldron."

"Master, you should have used the Myriad Things Cauldron long ago. That broken alchemy furnace struggles even to refine low-grade demonic pills, how could you expect it to produce top-grade ones?"

"That broken alchemy furnace was just for show. The people from the Heavenly Mystery Pavilion aren't stupid. If I came right off the bat and used the Myriad Things Cauldron to refine a top-grade demonic pill, wouldn't they be suspicious? There has to be a process. First, I need to make them think that I've tried my best and that the reason I can't refine a top-grade pill is because the equipment is faulty. Then I'll switch to a different piece of equipment and produce a top-grade pill instantly. Not only will they not be suspicious, but they'll also think I'm awesome."

Liu Mengli gave a thumbs up, "Master, you've got a whole repertoire of tricks up your sleeve."

Shen Yifei took the Myriad Things Cauldron out of his storage ring and placed it in the center of the room. The cauldron was two sizes larger than before, and its color was also darker.

"This cauldron has changed along with you."

Shen Yifei placed his hand on the cauldron and probed inside with his divine sense. The interior of the Myriad Things Cauldron was now larger than before, with two alchemy rooms next to each other, each five zhang square.

In the corner, Liu Mengli's little wooden house had also been upgraded, turning into a pavilion-like structure that looked much more luxurious.

The medicinal herb field has expanded considerably, and the herbs grow densely packed within it. The previously blurred boundary in the distance is now clearer, the outlines of several mountains are more distinct, and there appears to be a large body of water at their foot.

"This cauldron truly changes along with my cultivation level. Now that my spiritual energy contains demonic essence, it benefits from it as well. I'll need to find someone to manage this herb field..."

He divided the medicinal herbs into two portions and placed five pieces of magic ore next to the cauldron.

Refining demonic pills cannot be done with spiritual fire; it requires demonic fire. The few strands of demonic energy within him are currently too few to ignite demonic fire. But the Cauldron of All Things is different; this cauldron can transform itself.

He placed his hand on the cauldron, and dark golden spiritual energy surged into it. The black threads mixed in with the spiritual energy exploded inside the cauldron, turning into wisps of black flames.

Become!

The Cauldron of All Things can burn away demonic fire.

Shen Yifei put the first piece of ore into the cauldron.

The demonic ore rolled twice in the cauldron, enveloped by demonic fire. The surface of the stone began to crack, and black demonic energy seeped out from the cracks, like blood.

He added the medicinal herbs in the order specified on the prescription.

In less than an hour, a medicinal fragrance wafted from the cauldron. Surprisingly, Shen Yifei found the fragrance quite pleasant.

Shen Yifei extinguished the fire, and the lid of the cauldron popped open.

Six pills lay at the bottom of the cauldron. Each one was pure black, with a faint layer of runes flowing across its surface.

It's truly top-notch!

Shen Yifei picked up the six pills and examined them in his palm. Top-grade demonic pills; he had successfully refined six on his first attempt. They were even easier to refine than spirit pills. The refining principle of demonic pills was simple; there was no need to consider the synergistic or antagonistic interactions between medicinal ingredients. The core was to purify and shape the demonic essence.

At this moment, the little monster woke up from the aroma.

The little monster squatted in front of him, its mouth open, tongue lolling out, panting heavily. Its eyes were fixed on the medicine bottle in his hand, like a dog that hadn't eaten for three days seeing a bone.

"You want to eat the magic pill?"

The little monster nodded, drool dripping from the corner of its mouth and forming a puddle on the ground.

Shen Yifei tossed the pill into the air, and the little monster leaped up, caught it in its mouth, and swallowed the pill as it landed.

It licked its lips, stared at the medicine bottle in Shen Yifei's hand, and wagged its tail even more enthusiastically.

Shen Yifei gave it two more, and the little monster finally turned back onto the lid, satisfied.

Shen Yifei squatted down and took a look. The little monster's belly was bulging, and he could vaguely see black light flowing inside.

"These three pills should be enough for it to digest for a while!"

"Master, when do you plan to send the pills to Gu Yunyan?"

"No rush. We've said it for three days, we'll give it to you on the third day. Keep these two days free, take care of other things first."

"What is it?"

Before Shen Yifei could answer, there was a knock on the door.

"Senior Brother Shen, it's me." It was Green Ivy's voice.

Shen Yifei glanced at Liu Mengli, who then shrank back into the cauldron.

He opened the door, and Green Ivy stood in the doorway.

Today she wore a light purple outfit, and let her hair down, cascading over her shoulders. She was carrying a plate with several pastries on it.

"Senior Brother Shen, please try these pastries I made myself."

Shen Yifei stepped aside to let her in. Green Ivy placed the plate on the table, her eyes fixed on the floor.

"Senior Brother Shen, after I went back last night..."

"Does your lower abdomen still feel hot?"

"Hmm...not only does it feel hot, but it's also...a little itchy."
