Level 1 potions can be sold to earn magic stones, as Duke certainly can't use all of them himself, and he can also take orders from the Giant Rock Commerce Association to make money.

Duke effectively achieves multiple objectives with one allotment of time, thereby maximizing his use of it.

He quickly settled on the White Mist Forest Potion, a Level 1 potion. It's the most common type of meditation assistance potion and is suitable for many wizards.

The White Mist Forest Potion sells easily; once refined, it is certain to sell, which is why Duke chose this potion.

He didn't rush to take orders from the Giant Rock Commerce Association but instead bought several materials to start his own research and study.

The magic potion materials for the White Mist Forest Potion are relatively numerous, needing Fog Moss, Silver Leaf Grass, Calming Flower Bud, as well as Moon Dew Flower and Weak Magical Spring Water.

These are common Level 1 Magic Potion Materials, and their prices are considered mid to high-end among Level 1 materials.

A White Mist Forest Potion costs over seven hundred magic stones on the market, with raw material prices reaching four hundred. The combined cost of Silver Leaf Grass and Moon Dew Flower alone exceeds two hundred magic stones.

Once Duke received the raw materials, he entered his Magic Potion Laboratory to begin attempting to refine the potion.

Inside the lab, standard magic potion cauldrons, precise magic power temperature control devices, magic perception filters, and other equipment were all prepared. These are considered mid-quality magic potion equipment.

Among them, the standard magic potion cauldron even has a crystal liner, indicating a very high-quality type.

This equipment is entirely sufficient for refining a Level 1 potion, and unless something breaks, there's no need for replacement for the foreseeable future.

Duke has completely familiarized himself with the refining process of the White Mist Forest potion and has committed it to memory.

The laboratory was silent. He placed the Weak Magical Spring Water into the cauldron, heated it to 275°, then added the Fog Moss and Calming Flower Bud. Soon, a plume of white mist rose from the cauldron.

This white mist isn't pungent and has no toxicity; theoretically, it is a misty medication with a calming effect.

Duke did not let the white mist dissipate but used magic power to suppress it back into the cauldron.

...

The entire refining process of the White Mist Forest potion is very quiet, unlike the Blood of War, which has a more intense reaction process.

The refining time for this potion is not long, generally two to three hours, possibly faster if well-acquainted.

Three hours later, Duke held five white vials in his hand, each one containing the completed White Mist Forest Potion.

Seeing the change in the skill tree, Duke knew he had succeeded in refining the potion, sparing him the need to test the product.

After tidying the laboratory, he took one vial of the White Mist Forest Potion he had refined, returned to the castle, and consumed it to enter a meditative state.

When Duke drank this potion, it tasted sweet due to the Moon Dew Flower, Calming Flower Bud, and other sweet and palatable ingredients used.

However, this potion cannot be consumed as a beverage, at least not by ordinary people, as doing so would be akin to drinking poison.

After drinking the White Mist Forest Potion, Duke quickly entered a unique state, as if enveloped in a forest surrounded by white mist, with his mind particularly focused.

Meditating in this state is exceptionally efficient with significant improvements.

After several hours of meditation practice, Duke had nearly expended the potion's effects.

He then summoned Yala, Shari, and Nina, familiarizing them with the White Mist Forest refining process, and set them to handle simple magic potion material tasks.

Nina, being a Cat Girl, also possesses a degree of casting ability, albeit chiefly inclined toward physical enhancement, but fundamentally, she has energy manipulation ability.

Nonetheless, she still finds learning the Meditation Technique challenging, being better suited to the Knight path to learn the Breathing Technique.

For this race of Cat Girls, casting abilities are inherent, a talent embedded in their bloodline. Learning a wizard's knowledge proves somewhat difficult for them.

Yala, Shari, and Nina all took the task seriously, seeing it as a chance to demonstrate their own value.

Yala is the fastest learner among the three women, possessing great talent, and quickly grasped the entire White Mist Forest refining process.

As a Wood Elf, her ascension method differs from that of a wizard; in terms of spiritual power, she is equivalent to a first-class Wizard Apprentice.

Duke previously tested her; her spiritual power stood at 35 points, which is quite good, making her a helpful asset with proper nurturing.

...

In the laboratory, Yala and the other two wore specially designed robes meant for potion experiments, providing ample resistance to corrosion and toxins.

Typically, such protective wear is used by wizard apprentices, while official wizards generally do not require such protection.

With the participation of Yala, Shari, and Nina, Duke's refinement of the White Mist Forest Potion became much quicker, as they handled many of the simpler processes.

The three performed their tasks earnestly, accomplishing the tasks Duke assigned them well.

Where previously it took three hours to complete a White Mist Forest Potion, now the process can be done in under an hour.

This indirectly speeds up Duke's skill mastery pace and simultaneously boosts the rate of earning money.

To reward Yala and Nina, Duke decided the only option was to ramp up production, while Shari received support in terms of cultivation resources.

There was still a significant amount of Starlight Meditation Potion from previous refinements, which Duke gave to Shari to speed up her meditation practice.

After fully mastering the White Mist Forest Potion refining process, Duke began taking orders from the Giant Rock Commerce Association, simultaneously improving skill proficiency and earning money.

Three days later.

By that time, it was already deep into the night; Duke and the three women had been refining potions the entire day, and now it was time for meditation practice.

Yala, Shari, and Nina helped clean the lab, standardly disposing of some refining waste before heading to a designated room to remove their lab coats and wash their hands and bodies.

After taking off her lab coat, Yala displayed her exquisite figure, causing Shari and Nina to blush slightly.

She herself paid little mind; as a Wood Elf, she was long accustomed to close-to-nature states, feeling relaxed without her lab coat.

However, since following Duke, she realized the need to wear more clothing, at least refraining from being completely uncovered in front of others.

On the deserted island, this usually wouldn't be a concern, as there are no outsiders, and her fellow Wood Elves maintain their habits, only donning clothes when visitors are expected.
