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

Shen Yifei returned to the courtyard, closed the door, and laid out the seven medicinal herbs one by one.

Purple Ganoderma lucidum, Nine-Turned Polygonum multiflorum, Ambergris, Silkworm pupa, Blood Bodhi, Ice Soul Flower, and also a "Nascent Soul Fruit".

The Nascent Soul Fruit, three hundred years old, the size of a thumb, pure white, with nine golden lines on its surface.

He had heard people say in the alchemy room that this thing was the main ingredient for the Breakthrough Pill. A fruit tree only bears fruit once every thirty years, and only seven or eight fruits at a time. On the market, a single Nascent Soul Fruit sells for at least eight hundred spirit stones.

Qin Wan really used up all her savings for this Breakthrough Pill.

Shen Yifei thought about it again and felt something was wrong. Given Qin Wan's current strength, she simply couldn't produce that many spirit stones.

This person must be refining pills for someone else!

Looking at these medicinal herbs, Shen Yifei felt a little uneasy.

A fourth-grade elixir can definitely be refined using the Myriad Things Cauldron! If it's just Qin Wan consuming it herself, then it's fine. But if it's someone else, her secret might not be able to be kept!

If a mere servant who has just entered the inner sect can refine a top-grade fourth-rank pill, this news will cause an uproar not only in the Hehuan Sect but throughout the entire cultivation world.

But if we don't refine it, how will we explain it to Qin Wan? Using an ordinary alchemy furnace definitely won't work!

Shen Yifei pondered for a long time, then gritted his teeth and decided to refine it!

At worst, he could just confront Qin Wan and ask her to cover for him. After all, Qin Wan cultivated the Medicine Maiden's Heart Sutra and made a living from elixirs; they were in the same boat. If Qin Wan revealed his secret, he wouldn't get away with it either.

He took out the Cauldron of All Things and put the medicinal herbs in one by one.

Shen Yifei's heart stirred, and he channeled his spiritual energy into the device.

Fire burst forth from the cauldron.

This fire was different from before. It used to be red, but this time it was blue, burning eerily without smoke or heat. However, Shen Yifei could sense that the energy within the fire was more than ten times stronger than before.

The medicinal herbs slowly melted in the fire.

Purple Ganoderma lucidum turned into a purple liquid, Nine-Turned Polygonum multiflorum turned into a brown liquid, and Ambergris turned into golden oil... Seven medicinal herbs, seven colors, rolled and blended in the fire.

Shen Yifei's consciousness followed into the cauldron, watching the liquids slowly stir together, their color changing from rainbow to grayish-white, then from grayish-white to milky white, finally condensing into a ball, like a pigeon egg, spinning in the fire.

The fire is out.

At the bottom of the cauldron lay a pill, the size of a longan, with nine golden lines on its surface, exactly the same as the lines on the Nascent Soul Fruit.

Shen Yifei picked up the pill and brought it to his nose to smell it.

It doesn't taste like much.

He licked it again.

A pungent smell shot straight to the top of his head, so spicy that tears welled up in his eyes. Immediately afterward, the cloud of mist in his lower abdomen surged up, rampaging through his dantian, making his whole body numb.

Shen Yifei quickly spat out the saliva and drank a large bowl of cold tea to suppress the urge.

"Damn, this thing is really powerful." He wiped his mouth, put the Breakthrough Pill into a jade bottle, and put it into his ring.

Shen Yifei carefully put away the Breakthrough Pill, but his mind was racing with thoughts of it.

Who exactly authorized the refinement of Qin Wan's Breakthrough Pill?

Shen Yifei remembered the friend Qin Wan had mentioned, Su Yao!

Could it be that Su Yao provided the medicinal herbs and asked Qin Wan to help find someone to refine them?

It shouldn't be her either. Su Yao is in the late stage of Foundation Establishment, still far from the Golden Core realm. What would she do with the Breakthrough Pill?

If he couldn't figure it out, he stopped thinking about it. Shen Yifei put the matter aside for now, sat cross-legged on the bed, and began to ponder the second level of the "Yin Yang Absorption Technique".

He had almost mastered the first level. Although he hadn't formally absorbed any spiritual energy from anyone, he had become familiar with the path of spiritual energy circulation.

The second layer explains how to absorb the other person's cultivation techniques and talents during dual cultivation, which is much more effective than simply absorbing spiritual energy.

If you take spiritual energy, you can cultivate again; but if your talent is taken, you will never have the chance to cultivate again!

Shen Yifei flipped through a few pages and discovered that the second layer required a technique called "Spirit Locking Technique".

The principle behind this technique is not difficult: at the most crucial moment of dual cultivation, use spiritual energy to lock the intersection of the other person's dantian and meridians, and take advantage of the moment when the other person's cultivation stops to absorb the memory of that cultivation and spiritual energy together.

To put it bluntly, it was robbery.

They robbed the other party of their cultivation achievements, their understanding of cultivation techniques, and their innate talent and foundation.

The more Shen Yifei looked at the technique, the more sinister it seemed, but the more sinister it was, the more interested he became. In a place like the Hehuan Sect, if you don't eat people, they'll eat you.

Practice, you must practice.

He began to mimic the diagrams in the book. The key to the Spirit Locking Technique lies in the precise control of spiritual energy, which must be completed in an extremely short time without any mistakes; otherwise, the opponent will suffer a backlash.

For three days, apart from eating and sleeping, he practiced the second level continuously and finally made some progress. As for how far he could absorb it, he had no idea.

Qin Wan arrived early on the third day.

When Shen Yifei opened the door, he saw that there was another person following behind her.

She was a female cultivator, twenty-three or twenty-four years old, half a head taller than Qin Wan, with a more delicate face than Qin Wan, an oval face, phoenix eyes, thin lips, and an aloof expression.

"Junior Brother Shen, this is Su Yao, whom I told you about," Qin Wan introduced with a smile.

Su Yao looked him up and down. "You're Shen Yifei, the one who used dregs of medicine to achieve Foundation Establishment?"

Shen Yifei cursed inwardly. He was now labeled as a dreg of medicine, and he needed to find a chance to wash himself clean and let them see his true strength!

However, he still smiled innocently and said, "Hello, Senior Sister Su, I am Shen Yifei."

"Is the Breakthrough Pill ready?" Su Yao asked.

Shen Yifei glanced at Qin Wan and thought to himself, "As expected, it was a pill I made for her!"

Qin Wan nodded to him and smiled shyly.

"It's ready." He took out a jade bottle from his pocket and handed it over.

Su Yao took the jade bottle, poured out the Breakthrough Pill, and examined it carefully in her palm.

Seeing the nine golden lines flowing across the surface of the pill, a look of surprise appeared in her eyes!

"Nine Dao patterns? Did you refine this pill yourself?"

"Yes! Of course!"

Su Yao leaned closer to smell it, frowned slightly, and then stuck out the tip of her tongue to lick it.

Shen Yifei's throat involuntarily moved as he watched her lick the pill. Her pink tongue, the way it looked as she licked the pill, inexplicably reminded him of some rather indecent images.

Su Yao closed her eyes, seemingly sensing the effects of the medicine. After a while, she opened her eyes, and the look in her eyes as she looked at Shen Yifei had changed.

"To be able to refine a top-grade fourth-rank pill at the early stage of Foundation Establishment, Junior Brother Shen, you are a genius."

Shen Yifei was a little flattered by her praise, but he still maintained his honest and simple demeanor: "I'm just lucky, thanks to Senior Sister Su!"

"Luck?" Su Yao put the pill back into the jade bottle and tucked it into her bosom. "In all my years in the Joyful Union Sect, you're the first person to refine a top-grade fourth-rank pill!"

She pulled a storage bag from her bosom and tossed it to Shen Yifei: "This is your reward."

Shen Yifei took the storage bag; it felt heavy in his hand. He opened it and saw a neatly stacked pile of spirit stones inside, roughly counting them—at least five hundred.

"Senior Sister Su, this is too much." Shen Yifei said politely, but didn't hand it back.

Su Yao's thin lips curled up slightly, a rare smile appearing on her delicate face: "Not much, a Breakthrough Pill costs at least three thousand spirit stones on the market. Yours is top-grade, at least ten thousand spirit stones. I'll give you five hundred spirit stones, so I'm still getting a good deal."

"Ten thousand spirit stones?" Shen Yifei was shocked by this number!

"Junior Brother Shen, I've underestimated the quality of this pill, because no one has ever refined a top-grade one. If I take this pill and it works for me, please refine some for me when I need it. I won't treat you unfairly."
