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

Shen Yifei examined his fingers several times; they were smooth and bare. But he could vaguely feel something on his thumb, like an invisible band.

With a thought, a dark space suddenly appeared before him.

This space was many times larger than the storage bag he had just seen, at least the size of three or four rooms. It was completely empty, except for a few jade boxes and two books piled up in the corner.

With another thought, Shen Yifei produced a jade box in his hand.

Upon opening it, he found a lingzhi mushroom, purplish-red in color and about the size of a palm. He had worked in the alchemy room for three years and had seen many good things; this thing was at least a hundred-year-old purple lingzhi mushroom, which could be exchanged for several hundred low-grade spirit stones outside.

He then took out the remaining jade boxes, a total of five. Besides the purple lingzhi, there were two he shou wu (Polygonum multiflorum), one of which had taken on a human shape with complete roots and looked like a little baby; a blood ginseng; and the last one was ambergris.

Shen Yifei was beyond ecstatic. If all these medicinal herbs were exchanged for spirit stones, he would be the richest servant in the Hehuan Sect!

He put the jade box back into his ring and then took out the two books.

One book is "Crimson Flame Fist Technique," and the other is "Yin Yang Replenishment Technique."

Shen Yifei opened the "Yin Yang Replenishment Techniques," and the first page had eight large characters written on it: "Replenish Yin by absorbing Yang, replenish Yang by absorbing Yin." The following pages were filled with illustrations of naked men and women practicing dual cultivation, accompanied by textual explanations.

Shen Yifei seemed to understand, but not quite, and flipped through a few more pages. They were all about how to absorb spiritual energy from another person, how to circulate it, and how to avoid getting himself involved.

He recalled what had happened during the day; he knew nothing, yet he had managed to defeat that vicious senior sister. If she were to learn these techniques, what would become of her?

He sat cross-legged in the pile of firewood and began to mimic the diagram on it.

After practicing all night, just before dawn, he suddenly felt a heat in his lower abdomen, and his "little fish" suddenly swelled up, turning into a warm current that flowed throughout his body. His whole body crackled and popped, and a feeling of comfort permeated every bone.

He stood up, casually waved his hand, and with a "crash," the pile of firewood next to him flew out and smashed against the wall, scattering all over the ground.

Shen Yifei looked down at his hands and froze.

This strength is much greater than yesterday.

Just as I was in a daze, there was a knock on the door.

"Shen Yifei! Are you up yet? Time to get to work!"

He was the senior disciple of the alchemy room, surnamed Zhou, in the Qi Refining stage. He usually bossed around the other servants.

Shen Yifei quickly responded, put everything into his ring, and opened the door.

Senior Brother Zhou stood at the door, frowning as he glanced inside. "What did you do last night? You made such a mess."

"No... I didn't do anything. I was just a restless sleeper and kicked over a few piles of firewood."

"Alright, alright, hurry up and get ready, we have work to do today. Senior Sister Ye from the inner sect needs to refine a batch of pills, and she specifically asked you to assist her."

Shen Yifei's heart skipped a beat, and he hurriedly asked, "Senior Brother Zhou, which Senior Sister Ye?"

"Who else could it be? Ye Hongling, Senior Sister Ye!"

"What are you standing there for? Go on!" Senior Brother Zhou kicked him.

Shen Yifei braced himself and followed Senior Brother Zhou toward the alchemy room.

His heart was pounding. He had tormented that woman like that yesterday, and now she was asking for him by name. Was she planning to settle scores later?

Upon entering the alchemy room, they indeed saw Ye Hongling standing in front of the alchemy furnace.

She had changed her clothes; she wore a long, lake-green dress with a slender waist, making her stand there like a delicate onion. When she saw Shen Yifei enter, she raised her eyelids slightly, her face expressionless.

"Senior Brother Zhou, I've borrowed him. He'll come with me for today's work."

"Alright, alright, Senior Sister Ye is as useful as she gets." Senior Brother Zhou nodded and bowed, then glared at Shen Yifei, "Serve Senior Sister Ye well, do you hear me?"

Shen Yifei nodded and followed Ye Hongling out of the alchemy room.

The two walked one after the other on the mountain path, neither of them speaking.

When they reached a secluded spot, Ye Hongling suddenly stopped and turned to look at him.

Shen Yifei's heart tightened, and he took a step back.

"Senior sister..."

"What did you do last night?" Ye Hongling stared at him, her eyes red, as if she hadn't slept all night.

"No... I didn't do anything, I was just sleeping."

"I'm asking what you did to me?" Ye Hongling's voice was soft and weak. "Do you know that my cultivation level has dropped to the Qi Refining stage!"

Shen Yifei had no idea what the Qi Refining stage was, but judging from Ye Hongling's appearance, it seemed quite serious.

"Then... what should we do?"

"What am I going to do? You're asking me what to do?" Ye Hongling gritted her teeth in anger. "I spent ten years cultivating to reach the Foundation Establishment stage, and you knocked me back to the Qi Refining stage overnight. What are you going to do about it?"

Shen Yifei didn't know what to say, so he could only lower his head and listen to her scolding.

Ye Hongling cursed a few times, then suddenly stopped and stared at him, looking him up and down.

"You're coming back with me today. I've invited Senior Sister Zhao Xin; the two of us will work together to figure you out!"

When Shen Yifei heard that Ye Hongling had brought help, he was so frightened that he turned around and tried to run away, but Ye Hongling grabbed him.

Actually, his cultivation level was slightly higher than Ye Hongling's, but unfortunately he didn't know how to use spiritual energy, so he had to be dragged along by Ye Hongling, stumbling and falling all the way to the inner courtyard.

Soon, Ye Hongling stopped in front of a small courtyard, pushed open the door, and glanced back at him.

"Go in."

Shen Yifei steeled himself and stepped into the courtyard.

The courtyard wasn't large, with a few bamboo stalks planted inside and a stone table and benches in the corner. The door to the main house was open, and a woman's voice could be heard from inside.

"Hongling, have you brought the person?"

"I brought it."

Ye Hongling led Shen Yifei into the house.

A woman, in her early twenties, was sitting in the room. She was wearing a white dress and was even more alluring than Ye Hongling.

She was drinking tea when she saw Shen Yifei come in, and she looked him up and down.

"Him? A menial servant?"

"Senior Sister Zhao, don't underestimate him just because of his low status, he..." Ye Hongling bit her lip, "...he took my place."

Zhao Xin paused in her teacup and looked up at Ye Hongling.

"What did you say?"

"I said, he took advantage of me." Ye Hongling's face turned bright red. "Yesterday I was going to take advantage of that guy surnamed Liu, but this kid was peeping outside. I was going to take care of him too, but who knew... who knew he would take advantage of me in the end."

Zhao Xin put down her teacup, stood up, walked over to Shen Yifei, and circled him twice.

Shen Yifei felt uneasy under her gaze and lowered his head, not daring to move.

"Take off your clothes."

Shen Yifei stiffened, thinking, "It's over, they've really brought in help to take my life!"

But then I thought about it again. Ye Hongling's words just now confirmed that I had taken advantage of her, which meant that I had this hidden strength. In addition, I had practiced the technique of absorbing the essence of the body last night...

Thinking of this, he quickly took off all his clothes.

Zhao Xin looked at the naked Shen Yifei, her eyes gleaming. "You've got a good foundation, but I don't believe a lowly servant could have taken your essence! How did he do it?"

Ye Hongling stammered out the story, and her voice grew softer and softer as she lay on the ground, unable to get up.

"After three years of taking medicine residue, you've produced a freak? I'd like to test this freak out of you today!"
