43: He was almost dumbfounded.

Before long, Nangong Yu completely dispersed his Pill Fire, opened the cauldron lid, and peered inside, a hint of joy appearing on his face.

He saw ten Medicinal Pills quietly lying within, which made him feel a slight anticipation. They shouldn't bewaste pills, right?

On Xuanling Continent, if an Alchemist successfully condenses Medicinal Pills during Alchemy, the lowest grade will always bewaste pills.

waste pills are highly toxic pills that cause great harm to the human body and are unusable. Alchemists typically destroy them.

However, waste pills are only a hair's breadth away from Low Grade Medicinal Pills. If one can't even produce waste pills, then the Alchemy has truly failed beyond repair.

Nangong Yu channeled a stream of Spiritual Qi into the Medicine Cauldron, using it to draw out the ten Medicinal Pills, which landed on the jade plate he had prepared earlier.

He saw that all ten Medicinal Pills were smooth and bright in color, appearing to be of good quality.

And indeed, they were.

Although Nangong Yu was performing Alchemy for the first time, having mastered the foundations of the Dao of Alchemy, he could still discern the quality of these first-grade Medicinal Pills at a glance.

Nine of these ten rejuvenation pills were Special Grade, and the remaining one was High Grade.

In other words, his first attempt at Alchemy actually achieved a 100% Pill Production Rate, and even produced Special Grade Medicinal Pills.

Among Alchemists on Xuanling Continent, there are two concepts related to Alchemy: Pill Production Rate and Pill Formation Rate. These are completely different concepts.

Pill Production Rate refers to the number of Low Grade or higher Medicinal Pills you successfully form when theoretically ten pills should be formed. One pill is 10%, and ten pills are 100%.

Pill Formation Rate refers to the probability that an Alchemist will successfully form at least one Medicinal Pill after repeatedly refining the same type of Medicinal Pill.

And his first attempt at refining the rejuvenation pill resulted in a 100% Pill Production Rate. Although it was only a first-grade Medicinal Pill, it sufficiently demonstrated the terrifying assistance the Time-Space Merchant Guild provided him in mastering the Pill Formula.

Nangong Yu casually put the ten rejuvenation pills into the Time-Space Merchant Guild. After a moment of hesitation, he directly took out a set of Spirit Medicine for refining spirit nurturing pills.

Immediately, he exchanged two points for 10 liters of Spirit Water in the Time-Space Merchant Guild.

Spirit Water is water containing a small amount of Spiritual Qi. It's not very valuable, but it's essential for Alchemists to clean Medicine Cauldrons and for Artifact Masters to clean artifact furnaces.

Nangong Yu took out half a liter of Spirit Water, intending to use it to clean the Medicine Cauldron, but then he suddenly froze slightly.

He saw the void feather, as if knowing his thoughts, suddenly float up, invert, and gently vibrate, directly clearing all the Spirit Medicine residue from the Medicine Cauldron.

Even the medicinal fragrance of the rejuvenation pills inside the Medicine Cauldron was gone; it looked brand new, and it actually was!

Seeing this, Nangong Yu couldn't help but shake his head and smile. It seemed his void feather was indeed very spiritual and special!

No wonder it, an existence comparable to an Emperor Grade Medicine Cauldron, saved him, a first-rank Alchemist, so much Spiritual Qi, whether it was warming the Medicine Cauldron or performing Alchemy!

Nangong Yu reached out and touched the void feather, smiling slightly, "You've worked hard!"

The void feather vibrated slightly and landed on the ground again.

Nangong Yu didn't think much of it. After putting away the Spirit Water, he again formed hand seals, summoned his Pill Fire, and began to warm the Medicine Cauldron.

Before long, feeling it was about ready, he began to successively add Spirit Medicine for refining.

What he hadn't expected was that refining the second-grade spirit nurturing pills also went very smoothly, with no signs of failure appearing.

Two and a half hours later, Nangong Yu sensed something, and his expression became a bit more serious.

Immediately, he began to form hand seals, casting out one Pill Condensation Rune after another.

Before long, he saw the void feather vibrate slightly, clearly indicating that the Pill Condensation was complete.

Seeing this, Nangong Yu began to slowly lower the temperature of his Pill Fire, until he finally dispersed it.

Then, he again opened the cauldron lid and peered inside, seeing that there were still ten Medicinal Pills.

Nangong Yu couldn't help but smile slightly, using Spiritual Qi to draw out the ten Medicinal Pills onto the jade plate.

He glanced at them, and the result still didn't disappoint him: it was still a 100% Pill Production Rate, and moreover, there were eight Special Grade and two High Grade spirit nurturing pills.

This result alone was enough to make him happy.

A set of spirit nurturing pill Spirit Medicine costs about 1.6 points, but a Special Grade spirit nurturing pill sells for 7.2 points in the Time-Space Merchant Guild, and a High Grade spirit nurturing pill for 4.3 points.

If he were to sell this batch of Medicinal Pills to the Time-Space Merchant Guild, it would be 66.2 points.

If he could refine the other four sets of Spirit Medicine into Medicinal Pills with similar results, that would be roughly 331 points.

Minus the 88 points for the Pill Formula and five sets of Spirit Medicine, he could still net 243 points and one Pill Formula.

A huge profit!

Nangong Yu put away the spirit nurturing pills, pondered for a moment, then mentally messaged Ying Mei, asking, "Ying Mei, how is my mother's Cultivation progressing?"

Ying Mei's voice quickly came, "Reporting to Master, the Grand Madam's Cultivation is currently at a critical juncture. At this rate, she is expected to Breakthrough in three hours!"

Hearing this, Nangong Yu nodded slightly and continued to message, "Ying Mei, continue to act as Protector for my mother. Do not let anyone disturb her, and do not easily harm anyone who comes this way!"

"Yes, Master!"

Ying Mei responded, and Nangong Yu didn't concern himself further. He pondered for a moment, then simply took out the remaining four sets of Spirit Medicine for refining spirit nurturing pills.

With three hours left, he decided to try refining all four sets of Spirit Medicine at once.

His action wasn't a wild fantasy; it had a basis, which came from the foundations of the Dao of Alchemy.

The foundations of the Dao of Alchemy contained methods for simultaneously refining multiple sets of Spirit Medicine. Since he had mastered the foundations of the Dao of Alchemy, he naturally also mastered this method!

As if knowing Nangong Yu's thoughts, the void feather repeated its previous action, actively dry-cleaning the inside of the Medicine Cauldron, saving him the trouble of cleaning it.

Nangong Yu took a deep breath and continued to refine the spirit nurturing pills.

But an hour later, Nangong Yu couldn't help but be astonished. He stared dumbfounded at the forty Special Grade spirit nurturing pills that appeared before him, utterly bewildered.

He had used two and a half hours to refine one set of Spirit Medicine, but now, refining four sets of Spirit Medicine only took one hour. How could he not be surprised?

He stared blankly at the void feather, guessing that it must have been because of this fellow.

When he was performing Alchemy just now, the steps were the same as before, but the speed of refining the Spirit Medicine had at least doubled, which was why the time had been shortened so much.

He had been very surprised at the time, even causing a slight deviation in the temperature of his Pill Fire. He had thought that even if he succeeded, the quality of the Medicinal Pills would decline, but he never expected them all to be Special Grade!

In other words, although he didn't know the specifics, he knew that this void feather had actually helped him accelerate the refining speed of the Spirit Medicine and also helped him regulate the Pill Fire temperature, ensuring the perfect refinement of the Medicinal Pills.

It was... outrageous!

Nangong Yu took a deep breath, a glimmer flickering in his eyes, revealing a hint of inquiry.
