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

Shen Yifei was stunned for a moment after hearing Qin Wan's words.

"Need medicine?"

"Hmm." Qin Wan nodded, glancing at the alchemy room behind him. "I heard you took on an alchemy task and even bought medicinal herbs. I was wondering if you know how to refine pills?"

Shen Yifei thought to himself that the news had spread too fast; he had only received the task in the morning, and someone had already come knocking on his door in the afternoon.

"Senior Sister Qin, to be honest, this is my first time touching a pill furnace. I don't even understand how to control the heat, so how could I possibly refine any pills?" Shen Yifei scratched his head, looking rather simple and honest. "I was just thinking that since we have a pill room, I can learn slowly and refine pills after I've mastered it."

Upon hearing this, Qin Wan's expectation turned to disappointment, but she quickly put on a smile again: "Junior Brother Shen, don't be modest. You, a menial servant, were able to reach the Foundation Establishment stage by eating medicine dregs, that's truly exceptional talent. Perhaps one also has talent in alchemy."

Shen Yifei felt uncomfortable being praised by her, thinking to himself that this woman had a sweet tongue, but he wondered what she was up to.

"Senior Sister Qin, what kind of medicine do you want?"

Qin Wan said somewhat shyly, "The Aphrodisiac Pill."

Shen Yifei had worked in the alchemy room for three years. He had heard of the name of this pill and knew what it was used for. It was even more potent than the Bliss Pill. One pill could keep you going for three days and three nights.

"Senior Sister Qin, this medicine... isn't it readily available in the alchemy room? You can just go and get it, why are you asking me?"

A hint of unease flashed across Qin Wan's face as she bit her lip: "I'm out of spirit stones."

Shen Yifei understood.

According to the rules of the Hehuan Sect, inner disciples receive a fixed monthly salary and two bottles of Qi Gathering Pills.

But that's only enough for daily cultivation. If you want to buy better items, you have to find your own way. You either have to do sect missions to exchange for spirit stones, go down the mountain to train and search for treasures, or rely on dual cultivation.

The Joyful Union Sect originated from dual cultivation, where male cultivators cultivate female cultivators, and female cultivators cultivate male cultivators, mutually benefiting each other. Those with the ability can enhance their cultivation by absorbing the other's essence, while those without the ability become the vessel for others to cultivate.

Qin Wan, being only at the mid-Foundation Establishment stage, wouldn't necessarily become a furnace cauldron, but she was definitely short of money.

"Junior Brother Shen, if you can help me refine a batch of Aphrodisiac Pills, I... I'll cultivate with you."

Shen Yifei's eyelids twitched.

He looked Qin Wan up and down. Her neckline was quite low, making her look bulging. Her face was fair and delicate, so she was considered quite attractive.

"Senior Sister Qin, you've gone too far with that joke. You're in the mid-Foundation Establishment stage, while I've only just entered it. For me to cultivate with you would be like offering myself up as food!"

Qin Wan became somewhat anxious upon hearing this. "Junior Brother Shen, the way you're saying it makes it sound like I'm here to exploit you for sustenance. I genuinely want the medicine, I don't want to harm you. If you don't trust me, we can sign a contract. During our dual cultivation, we won't use any cultivation techniques, it will just be pure dual cultivation."

Shen Yifei understood.

Pure dual cultivation means neither absorbing nor replenishing, only enjoying pleasure without increasing cultivation level.

This also happens in the Hehuan Sect, mostly between Daoist couples to enhance their relationship, or like Qin Wan, who, when short of spirit stones, uses her body to pay off her debts.

"Senior Sister Qin, who is this Aphrodisiac Pill for?"

Qin Wan's expression became even more unnatural. After stammering for a long time, she finally whispered, "For my own use."

"For your own use?"

"Hmm." Qin Wan lowered her head. "I encountered a problem in my cultivation, my yin and yang are unbalanced, and I need to use the Joyful Union Pill to regulate it. But I've spent all my spirit stones, and when I went to the alchemy room to get more, I didn't complete the task, so I couldn't get any..."

She looked up, her eyes red-rimmed: "Junior Brother Shen, please help me. I don't need you to provide the herbs, I have my own. Just help me refine them, and I'll practice dual cultivation with you three times, no, five times!"

Shen Yifei looked at her red-rimmed eyes and felt a pang in his heart.

This woman doesn't seem to be faking it. If she really wanted to harm him, she wouldn't need to be so subservient.

"What about the medicinal herbs?"

Qin Wan was taken aback, then overjoyed. She pulled out a storage bag from her bosom and poured out a bunch of things: Dragon Yang Grass, Deer Antler, Epimedium, Cistanche deserticola... all medicinal herbs to enhance pleasure, along with a small bottle of Albizia Powder and a few unknown herbs.

Shen Yifei looked at them and realized that all of these items together were worth at least two hundred spirit stones.

"Senior Sister Qin, you have a very complete selection of medicinal herbs. Why don't you refine them yourself?"

Qin Wan blushed again: "I don't know how..."

Shen Yifei nodded: "Okay, I'll give it a try. But let me make this clear, this is my first time refining pills, so don't blame me if I mess it up."

"No, no, it's not my fault!" Qin Wan waved her hands repeatedly, "It's enough that you're willing to help me!"

Shen Yifei told her to wait outside while he carried the medicinal herbs into the alchemy room.

He closed the door, took out the Myriad Things Cauldron, and poured all the medicinal herbs into it.

Infuse your mind with spiritual energy and silently recite "Hehuan Dan" (a type of herbal medicine).

It still caught fire.

This time he watched carefully as the medicinal herbs in the furnace slowly melted, turning into a pool of reddish-brown liquid. The liquid churned, condensed into a clump, and finally broke into a dozen or so grains.

When the fire in the furnace went out, fifteen pills the size of longan fruits, red in color, lay at the bottom of the cauldron.

Shen Yifei picked up one and smelled it. It was indeed a Hehuan Pill, and its quality was even better than the ones he had seen before.

He put the elixir into a jade bottle and pushed open the door.

Qin Wan was standing in the courtyard, craning her neck to look into the alchemy room. When she saw him come out, her eyes lit up.

"Junior Brother Shen, how is it?"

"It's done." Shen Yifei handed her the jade bottle. "Fifteen pieces, enough for your treatment."

"This...it's finished so quickly?" Qin Wan looked incredulous.

She took the jade bottle, poured out a piece, looked at it, smelled it, and her eyes reddened again.

"Junior Brother Shen, you are truly... truly amazing!" She looked up, her eyes sparkling. "I'll join you in dual cultivation right now!"

"Wait a minute." Shen Yifei stopped her. "Senior Sister Qin, there's no rush for dual cultivation. You should take the pills first and get your body in order before we talk about it."

Qin Wan was stunned for a moment, then realized that the other person didn't like her looking sickly.

"Junior Brother Shen, you...you're so kind." She lowered her head and said softly, "Then...I'll come again when I'm better."

After Qin Wan left, Shen Yifei closed the courtyard gate and leaned against the door, laughing for a long time.

This is a good deal.

He helped someone refine one batch of pills in exchange for five sessions of dual cultivation. Although it was supposed to be "pure dual cultivation" without any external aids, it was still dual cultivation. He had been holed up in the woodshed for three years; he had never seen anything like this before.

As for Qin Wan, although she wasn't a stunning beauty, she was fair-skinned and well-proportioned, and her breasts were plump and soft to the eye.

As Shen Yifei pondered, that warm current began to surge within his lower abdomen again. He quickly took a deep breath, suppressed his wandering thoughts, and returned to his room to sit cross-legged.

No, I can't just keep thinking about that.

He took out the Myriad Things Cauldron and examined it from all angles. Today's batch of Acacia Pills had given him a deeper understanding of this treasure. It could refine people and pills—just what was its origin?

Senior Brother Liu died under mysterious circumstances, and all these things benefited him.

Shen Yifei took out the book "Yin Yang Sexual Enhancement Techniques" and flipped through it from beginning to end.

This book has three layers.

The first level is the basic method of absorbing yang energy to replenish yin energy and absorbing yin energy to replenish yang energy. It explains how to absorb the other person's spiritual energy during dual cultivation and make it one's own.

The second level is an advanced version of the "Supplemental Absorption Technique," which not only allows you to absorb spiritual energy but also the other person's cultivation techniques and talents.

The third level is the most ruthless, called the "Foundation-Seizing Technique," which can directly seize the opponent's foundation, along with their realm and talent.

Shen Yifei felt a chill run down his spine when he saw the third floor.

If the Hehuan Sect found out that he had this book, they would chop him into mincemeat!

Shen Yifei began to make plans in his mind.

Refining Zhao Xin and Ye Hongling was an accidental use of the Human Refining Technique of the Myriad Things Cauldron.

That thing is somewhat similar to the third level of the Yin-Yang Absorption Technique; both involve seizing a person's foundation. However, the Myriad Things Cauldron is even more ruthless, directly refining the entire person into spiritual liquid and swallowing them whole.

If one could master the Yin-Yang Absorption Technique and combine it with the Myriad Things Cauldron, wouldn't that be incredible?

If he sucks and eats at the same time, he will soon be invincible!
