To be honest, Meng Yirou had encountered many proud masters before, especially those who refined medicine, but someone like the person in front of her, who dared to belittle even the Palace Master of the Divine Medical Palace, was rare. If word got out, it would surely cause an uproar.

Could he really be just an ordinary person?

Or did he truly believe his medicine refining skills were so superior, even surpassing the Palace Master of the Divine Medical Palace, allowing him to casually criticize the techniques taught to his disciples?

Meng Yirou doubted such a person could exist.

The saying goes, "There are always people better than you, and skies beyond skies," but there must be a limit, right?

Bai Fei'er couldn't help but smile, her excitement barely contained as she said, "Saintess, don't misunderstand. Senior Gu is not an arrogant person. He truly saved me and granted me a second life."

Meng Yirou huffed, her lips pouting high in indignation. She was as aggrieved as one could be.

How could she not be?

This wasn't just about her own reputation; it concerned the entire Divine Medical Palace. Now, the Palace Master was being belittled, and he was the most skilled and mysterious in medicine refining in the entire palace.

This insult, let alone the Palace Master, even Meng Yirou found hard to swallow.

Gu Heng glanced at her but didn't argue.

His medicine refining skills were "superb," and he couldn't possibly lose this argument unless Yirou's master was a cultivator. But even then, a cultivator could only teach her to refine simple pills, which was quite useless. Besides, this young girl was too young for him to argue with. Who was she, anyway? She probably only came to this shabby Medicine Hall because Bai Fei'er dragged her along.

Meng Yirou suddenly felt embarrassed, especially in front of Bai Fei'er. Gu Heng's words hit her right in the heart.

She took several deep breaths, trying to suppress her anger and shame, then calmly said, "Yes, maybe you think my skills are lacking, but I've seen my master refine medicine. Since you belittle him as well, please, Young Master Gu, open the furnace and refine some pills for me to see."

Gu Heng raised an eyebrow. "You want to see me refine pills?"

Meng Yirou nodded without hesitation.

It can be hard to make great work when its stolen from "p𝑎wread.com".

Since this guy had belittled her and her master so much, she wanted to see what he was capable of!

With things at this point, it was impossible for Meng Yirou to swallow this "bitter pill" without complaint.

She had pride, or rather, all medicine refiners had pride. If someone was to instruct them so bluntly, the other party should at least have the qualifications, right? But so far, Meng Yirou couldn't see what qualifications Gu Heng had, except for the unwavering belief of Bai Fei'er beside her.

But seeing is believing, and Meng Yirou wanted to see for herself!

However, Gu Heng was a bit hesitant.

Not because of anything else, but because his method of refining medicine wasn't like other ordinary doctors who learned step by step from a master, following very traditional techniques. Instead, he learned from the System, increasing his proficiency bit by bit.

These two methods were worlds apart.

Because the materials he used, other ordinary doctors couldn't possibly use to refine medicine. If this wealthy lady saw his method and exclaimed, "You're a heretic," it would be hard for Gu Heng to continue.

Of course, Gu Heng wasn't too worried about this because Meng Yirou wasn't proficient in medicine refining. She knew how to make pills look good, but the efficacy was poor, indicating she hadn't learned well. Even if she watched, she probably wouldn't see the difference, as there wasn't a seasoned ordinary doctor watching alongside her.

Moreover, he had an advantage: he could show off!

This wealthy lady had probably never seen someone use one furnace to refine two different types of pills simultaneously.

Well, Gu Heng could do it, and he could do it skillfully. He could even refine seven different types of pills at once, although no one had seen this technique yet.

It's not that he didn't want to show it, but as an ordinary person, showing off by refining "seven different pills at once" was less interesting than watching a traveling theater troupe.

With this thought, Gu Heng wasn't afraid anymore.

So he agreed readily, "Alright, since you're sincerely asking for guidance, I'll let you see."

Bai Fei'er was initially surprised that he agreed, but then she was overjoyed. Watching a medical sage of such high skill refine medicine was a rare opportunity!

Why do strong medicine refiners always attract many onlookers? It's because the "skills" they display while refining are immensely beneficial for cultivators to solidify their foundation and comprehend their intent. Some even break through just by watching a strong refiner at work, which isn't uncommon.

The two women followed Gu Heng to the back room.

The back room was mostly tidied up. The forge had been stored in the System Backpack, and the old tables and chairs were left there since Brother Wu had given him enough money to buy new ones in White Emperor City.

Seeing the simple environment, Meng Yirou frowned but said nothing.

Though simple, it was clean.

She wasn't there to see a lavish palace.

Moreover, there was only a very ordinary iron pot in the back room. Meng Yirou could tell it wasn't made of any precious metal or inscribed with any spiritual arrays. It was just ordinary. Could such a pot be used to refine "Star-Moon Divine Water"?

Impossible, right?

The spiritual pills and medicines ranked in the top 15 of the Divine Medicine List were all extremely powerful when completed. This iron pot probably couldn't withstand the forces released during the refining process.

Unless the refiner could completely control every bit of useless medicinal power that escaped, making even such a fragile iron pot remain unscathed.

But to have such exquisite, even terrifyingly precise skills, one would be worthy of the title "Medical Sage" and wouldn't need to use such crude ordinary tools, as they would only increase the difficulty of refining. They would have excellent medicine cauldrons and pill furnaces.

It seemed "Senior Gu" didn't have those.

Now, Meng Yirou was still very skeptical of this "senior master."

Gu Heng took out his pill furnace from the storage cabinet and placed it beside the stove.

...Was he going to use this to refine pills?

Meng Yirou was a bit stunned.

Because this pill furnace... was of normal size and painted in vermilion, although somewhat attractive, it was still an ordinary item.

Meng Yirou now dared not say much, as Gu Heng's pill refining from the start was beyond her imagination. She might as well watch quietly and see what he could do.

Gu Heng had already decided which pills to refine—three with different effects: one to replenish qi and blood, one to heal internal injuries, and one to invigorate the mind. Simple, but refining them simultaneously and producing them at the same time would surely amaze Meng Yirou.

With a flip of his hand, he took out three sets of pre-measured ingredients from the System Backpack and tossed them in almost instantly.

His hands moved quickly; otherwise, Bai Fei'er and Meng Yirou would notice and wonder how an ordinary person could retrieve items from a Mysterious Ring like a cultivator.

But Meng Yirou still caught what those ingredients were.

And then she was shocked!
