As the woman walked further and further away, Lu Yuan picked up the white coat hanging behind the door and put it on, then took a mask from the table and put it on his face.

He calmly walked into the pharmaceutical room, passing several small laboratories along the way. The pharmacists inside glanced up at Lu Yuan, then continued with their work, clearly unaware that an outsider had infiltrated.

Seeing this, Lu Yuan smiled slightly and strolled around casually.

"Finally found an empty laboratory."

Lu Yuan's face lit up with joy as he entered the laboratory.

He found various medicinal herbs on the table, and after counting them, he realized that they were exactly the herbs he needed.

Lu Yuan picked up the medicinal herbs directly, recalling the refining method of low-grade body-tempering potions.

In an instant.

He felt himself falling into a very mysterious state, as if everything around him had become nothingness, and all he could see were the medicine furnace and various instruments on the table.

Immediately afterwards.

Lu Yuan's hands moved swiftly, like a precise robot, constantly picking up various medicinal herbs to refine, and then putting them into the medicine furnace in a certain proportion.

Soon, a fragrant aroma wafted from the medicine furnace, and just smelling it was enough to invigorate one's spirits.

"It's done!"

Lu Yuan's eyes lit up as he carefully poured the medicine from the furnace into bottles.

[Low-grade Body Tempering Potion: Slightly increases stamina and endurance. Restores some consumed stamina upon use. Suitable for Beast Tamers below the Profound Realm level.]

"Only applicable to beast tamers below the Xuanzhen level?"

Lu Yuan frowned.

Mid-grade body-forging potions are applicable to Earth Spirit level to Heaven Evolution level. The medicinal materials used in their preparation are the same, but both the required quantity and the difficulty of preparation will increase exponentially, and the selling price will naturally double as well.

However, to his delight, he successfully refined a total of eight bottles of body-strengthening potions this time.

Under normal circumstances, depending on the skill level of the pharmacist, two to five bottles of low-grade body-strengthening potion can be refined.

An average pharmacist can only produce two or three bottles, and there is a very high chance of failure.

But Lu Yuan directly surpassed the highest level, refining eight bottles in one go!

"Isn't it a bit too much to refine eight bottles of body-strengthening potion at once? If people find out, they'll lock me up and make potions for me every day!"

Lu Yuan couldn't help but recall the scene of himself being locked in a dark room, trembling under the whip, and refining medicine day and night.

Just then, footsteps suddenly sounded.

Lu Yuan snapped out of his daze and quickly put six of the bottles of medicine into the warehouse.

The next second.

The laboratory door opened, and two people in white coats walked in.

"Who is it? Didn't I tell you that you're not allowed in this lab?" Wei Xueyu frowned, her eyes showing displeasure.

Depend on!

It's that woman again! She's like a persistent ghost!

Lu Yuan's heart sank slightly.

Unexpectedly, I ran into Wei Xueyu again.

"Sorry, you've gone to the wrong place."

Lu Yuan nodded and turned to leave as if nothing had happened.

"etc!"

Wei Xueyu immediately stopped him, "Take off your mask!"

Lu Yuan was startled.

Wow!

He's dressed like this, how could this woman still recognize him?

Subconsciously pulling down his mask, Lu Yuan said in a low voice, "I have a cold, so it's inconvenient for me to take off my mask."

"It's you!" Wei Xueyu reacted instantly. "You're the man who sells the body-strengthening herb!"

"Seriously, sis? Do you have a crush on me? You still recognized me even though I was all covered up!"

Unexpectedly, Wei Xueyu reacted so quickly that Lu Yuan had no choice but to take off his mask.

"Who let you into the lab?" Wei Xueyu asked angrily, not expecting Lu Yuan to dare to barge into the pharmaceutical room without permission.

“Mr. Wei has given his permission.” Lu Yuan rolled his eyes, his expression full of disdain and contempt.

"you……!"

Wei Xueyu was so angry at Lu Yuan's attitude that her face turned red. She pointed at him with her slender fingers, but she couldn't say a word.

"What? Go ahead and bite me if you dare!"

Lu Yuan looked on with disdain.

Just when the two were at an impasse...

"Huh? I don't remember having these potions before!"

The man who came in with Wei Xueyu suddenly looked at the experimental table and saw two bottles of body-strengthening potion on it.

He stepped forward, took the medicine in his hand, and examined it carefully.

"Is this a low-grade body-strengthening potion?"

He exclaimed in surprise, looking at Lu Yuan in disbelief, "I clearly put away all the potions on the table when I left, could you have made these?"

Lu Yuan smiled slightly, "It was just refined, and we haven't determined its quality yet!"

The man looked down at the potion in his hand and murmured, "Without specialized equipment, we can't determine its specific grade, but judging from its color alone, it's at least top-grade!"

Upon hearing this, Wei Xueyu, who was standing next to her, immediately became anxious.

"How is this possible?!"

She snatched the potion from the man's hand and examined it closely, only to find that it was perfect in every way.

"How is this possible... This potion looks even better than the finished product concocted by Master Kong!"

Wei Xueyu was completely dumbfounded.

She originally thought that Lu Yuan was just a lucky kid who had somehow found a large number of high-quality body-strengthening herbs, which impressed her cousin. But in the end, he didn't have any real skills. That's why she offered to spend money to buy the source of the body-strengthening herbs.

She even had a big argument with Wei Zheng because of this.

Unexpectedly, Lu Yuan actually knew how to make medicine!

Moreover, its quality is absolutely top-notch!

"If you can't believe it, it just means you need to get your hair trimmed!" Lu Yuan said casually.

"hair?"

Wei Xueyu touched her long hair in confusion, and then realized what was going on when she met Lu Yuan's teasing eyes.

"You're swearing!"

"Wow! You actually figured it out. Looks like you're not too stupid."

Lu Yuan smiled knowingly.

Wei Xueyu was so angry that her face turned red, but she couldn't say anything. She couldn't possibly admit that she was short-sighted!

"If there's nothing else, I'll be going now!"

Lu Yuan took the two bottles of medicine from Wei Xueyu's hand, turned around and prepared to leave, not afraid at all that Wei Xueyu would cause him trouble.

After all, he had Wei Zheng's permission. Compared to the person in charge of the entire Spirit Medicine Hall, Wei Xueyu was just the manager of the medicine preparation room, and his words carried no weight.

"etc!"

"What's wrong now?"

Lu Yuan turned to look at Wei Xueyu, his tone already showing some impatience.

This woman has caused him trouble time and time again. He's only been able to tolerate her this long because of Wei Zheng. If she continues to cause trouble, he wouldn't mind teaching her a lesson!

Wei Xueyu hesitated for a moment, then took a deep breath before asking, "Besides body-strengthening potions, can you also concoct other potions?"

"Why should I tell you?" Lu Yuan said calmly.

Wei Xueyu hesitated for a moment, then solemnly said, "I hope you can sell me these two bottles of body-strengthening potions!"

Wei Xueyu felt a pang of regret.

He shouldn't have underestimated Lu Yuan just because he was young.

In the end, it turned out that the clown was herself!

"Like I said, why should I sell it to you?"

Lu Yuan shook his head and looked at Wei Xueyu with a mocking expression.
