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

Shen Yifei took the jade box and opened it a crack.

The spiritual energy of the Fire Spirit Mushroom seeped out from the cracks, raising the temperature of the entire medicine room. A sixth-grade medicinal herb, indeed no ordinary item.

Zhou Yuanqing explained, "The Fire Spirit Mushroom, if refined into a pill, can quickly replenish lost vital energy. This is a rare treasure of our Hehuan Sect."

Upon hearing about the effects, Shen Yifei tucked the jade box into his pocket and patted Zhou Yuanqing on the shoulder.

"Elder Zhou, I accept this gift. If you ever need my help in the future, please don't hesitate to ask."

Zhou Yuanqing cupped his hands in greeting: "Elder Shen, you're too kind."

Shen Yifei walked around the medicine room, searching through the medicine cabinets from top to bottom. The Hehuan Sect's reserves of medicinal herbs were even more abundant than those of the Qingyun Sect.

He found several more medicinal herbs to replenish his vital energy, intending to refine them into elixirs with the Fire Spirit Mushroom. Whether he could escape from Su Wuwang alive tonight was the key.

Shen Yifei returned to his residence in the Hehuan Sect, closed the door, and took out the jade box, placing it on the table.

"A sixth-grade fire spirit mushroom, Old Man Zhou is quite generous." Liu Mengli floated out of the cauldron, leaned over the table and stared at the spirit mushroom. "This thing would sell for at least twenty or thirty thousand spirit stones outside. He's been saving it for almost a hundred years, and he just gave it away like that."

"He's not being stingy, he's being clever." Shen Yifei flipped the Ganoderma lucidum over. "I was parachuted into the alchemy room as an elder, and his original position was gone. If I were determined to get rid of him, he wouldn't have lasted a day in the alchemy room. By returning the real power to him, I've essentially saved his position. His gift of the Fire Ganoderma lucidum is a way of returning the favor."

Shen Yifei took out the medicinal herbs he had previously scavenged from the alchemy shop from his storage ring and laid them out on the table. Yangqi stone, Cynomorium songaricum, deer antler glue, and Cistanche deserticola were all herbs that replenish vital energy.

Liu Mengli glanced at the pile of medicinal herbs on the table, her lips twitching. "Are you planning to concoct an aphrodisiac?"

"What aphrodisiac? This is called Yuan Yang Pill." Shen Yifei divided the medicinal herbs according to the dosage. "Su Wuwang is in the mid-stage of the Nascent Soul realm, and the pure Yin energy in his body is more than ten times stronger than Yin Wuxie's. If I don't replenish my Yuan Yang in advance, no one will even collect my body if I die in her bed tonight."

When he worked as a handyman in the pill refining room, he saw people refining this pill. However, those Yuan Yang pills were of very poor quality, had poor effects, and were extremely wasteful of medicinal materials, so very few people refined them.

He placed the Cauldron of All Things on the ground, and the monster on the cauldron opened its eyes. When it saw the Fire Spirit Mushroom, its eyes widened, its mouth opened wide, and its tongue stuck out as it panted heavily.

"Don't even think about it, this isn't for you to eat." Shen Yifei broke off a small piece of the Fire Spirit Mushroom and tossed it to the animal. "This is all, there aren't any more."

The monster swallowed it whole, smacked its lips twice, and wagged its tail, seemingly satisfied.

Shen Yifei sat down cross-legged and threw the Fire Spirit Mushroom and other medicinal herbs into the Myriad Things Cauldron one by one.

Dark golden spiritual energy surged from his palm and flowed into the cauldron. The furnace fire ignited, the flames licking the cauldron's walls with a whooshing sound.

After an incense stick's time, the fire in the furnace went out. Lifting the lid, six crimson pills lay inside, each one round and glistening with a faint golden light.

Shen Yifei waited until late at night before taking a pill before leaving the house. After the pill entered his mouth, a surge of scalding heat flowed into his dantian along his meridians.

Shen Yifei felt as if his whole body was on fire, with the heat rushing through his meridians. It took about the time it takes to drink a cup of tea for the heat to gradually subside.

"The effect is good. You're like a stick now. Su Wuwang is in luck tonight."

He took a bath, changed into clean clothes, put the remaining five Yuan Yang Pills in his ring, and headed towards Su Wuwang's bedroom.

Su Wuwang's sleeping quarters are located in a separate courtyard on the back mountain of the Hehuan Sect.

The door to the sleeping quarters was ajar, and warm yellow light shone from inside.

Shen Yifei stood at the door, took a deep breath, and pushed the door open to go inside.

Su Wuwang leaned against the soft couch by the window, holding a cup of tea in his hand.

She changed into a moon-white nightgown, the material so thin it was almost translucent, and there was nothing underneath.

Her hair, black and glossy, cascaded down her shoulders to her waist. The light shone on her, making her look like a statue sculpted from white jade.

Shen Yifei stood at the door, his gaze lingering on her for a moment before shifting away.

"You're here." Su Wuwang put down his teacup, beckoned to him with his finger, "Come here."

Shen Yifei walked over and stood by the soft couch. Su Wuwang looked up at him, reached out and grabbed his belt, and gently tugged it, loosening it.

"I have been waiting for you for a long time."

Shen Yifei looked down at her. In this posture, at this angle, when she tilted her face up, she was extremely alluring.

He reached out and pinched her chin, pressing his thumb against her lips.

Su Wuwang didn't dodge. Instead, he opened his mouth slightly and gently bit his thumb with his teeth, like a kitten grinding its teeth.

Su Wuwang opened her mouth, turned around, and sat down on the edge of the bed. She patted the spot next to her, "Come sit down."

Shen Yifei walked over and sat down. Su Wuwang turned to face him and reached out to unbutton his collar.

"I know you feel like I'm forcing you." She stopped unbuttoning the third button. "But have you considered that the benefits you gain from dual cultivation with me are no less than mine? My hundreds of years of pure Yin energy are enough to push you from the early stage of the Golden Core realm to the late stage. Moreover, your constitution is special. After my Yin energy merges with the Yang energy in your body, the quality of your spiritual energy will rise to another level."

She paused, then continued unbuttoning the buttons.

"This is a fair trade; neither of us will lose out!"

"Fair trade." Shen Yifei repeated these four words, grinning, "Sect Master, you're talking like you're doing business."

"It's all business anyway." Su Wuwang's hand continued to probe downwards from her abdomen. "There's no such thing as love or affection in the cultivation world; it's all about exchanging benefits. I give you cultivation, and you help me break through my bottlenecks. Nobody owes anyone anything."

Shen Yifei grabbed her wrist, and Su Wuwang frowned slightly.

"Sect Master, since we're doing business, we need to agree on the price first."

"Price?" Su Wuwang chuckled. "Isn't my hundreds of years of pure Yin energy enough?"

"Not enough." Shen Yifei removed her hands from his body. "Your pure Yin energy is yours. How much I get depends on how much I can withstand. If you drain me dry, who will I cry to?"

Su Wuwang stared at him for two seconds, then suddenly smiled.

"You're the first person who dares to negotiate a price with me." She leaned back against the headboard. "So, what do you want?"

"Three things." Shen Yifei held up three fingers. "First, I will have priority access to the medicinal herbs in the pill refining room. I won't need to ask anyone what herbs I want to use to refine any pills."

"Alright. You're the elder of the alchemy room, so you're in charge of the medicinal herbs. That's how it should be."

"Secondly, I want free access to the Hehuan Sect's cultivation technique pavilion. I can see whatever I want on the floors below the third floor."

Su Wuwang's brow twitched slightly. The first three floors of the Cultivation Techniques Pavilion housed the core cultivation techniques of the Hehuan Sect, which had always been accessible only to elders. Shen Yifei, having just become an elder, demanded this access; his appetite was quite large.

"Okay. But for techniques above the third level, you'll have to exchange them for contribution points."

"Deal." Shen Yifei held up his third finger. "Third, after tonight, you can't use me as a cultivation vessel. Dual cultivation is dual cultivation, and a cultivation vessel is a cultivation vessel; they are two different things. I am an elder of the Hehuan Sect's alchemy department, not a regular guest in your bed."

Su Wuwang stared at him for a long time.

A powerful cultivator in the Nascent Soul stage was being negotiated with face-to-face by a mere Golden Core stage youth, yet she not only didn't get angry, but instead found it amusing.

"Alright, I agree. But there's one condition: you must come when I need you. Not permanently, but you can't refuse to come either."

"How often?"

"It depends on my cultivation progress. It could take as little as a month or as long as half a year."

Shen Yifei thought for a moment and nodded.

"Okay. Shall we begin?"

Su Wuwang didn't say anything, but reached out and pulled him down onto the bed.
