Wizard: I use my omniscience to interpret the truth.

Leaving the spire, Byron did not linger and headed straight for the marketplace.

He dared not waste any time; if he did, and something went wrong, he would be the one crying.

After speeding all the way to the market, Byron went straight into a steel and wood building called "Sol Materials Shop".

Because he had been in charge of the tutor's purchasing with Coron during this period, he had developed a certain acquaintance with the shop owner, Karen, a fat man whose body was jiggling with fat.

"Manager Karen, I need the materials on the purchasing list."

Byron got straight to the point, his voice cool and detached.

Karen, who had been lounging lazily in the chair behind the counter, noticed that Byron was the only one there, and a hint of surprise flashed in her narrowed eyes.

"Oh, Byron, running errands for the wizard Isolde again? Why are you alone this time? Where's that guy Corin?"

Koren skillfully pulled over the ledger.

Byron shook his head: "No, this is my personal purchase, it's not on my mentor's tab."

Byron needs to make this clear, otherwise Karen will be making a huge mistake by putting him on the mentor's list.

Karena's fat, which had been bunched up because of her smile, froze.

He suddenly sat up straight, his almost invisible eyes widening as he stared intently at Byron.

"You...you've been promoted to wizard apprentice?"

Karen's voice sounded sharp and distorted due to excessive shock.

He knew very well that Byron had only been in the college for a little over half a month.

Back then, it took him more than half a year to become a wizard apprentice.

Anyone who understands wizards can see the difference.

Byron smiled slightly at Karen's shock, then quickly read out the materials he needed.

"Manager Karen, I need one...two portions of Twilight Grass, Silvervein Fern, Soul Breath Grass...in pure water."

He wasn't worried that Karen would be able to deduce the formula from these materials.

In the wizarding world, the same materials can give rise to countless possibilities through different combinations of mental guidance frequencies, placement orders, and extraction methods.

These newly created potions may possess special effects, or they may be poisons capable of causing instant death.

Therefore, it is wishful thinking to try to deduce a complete potion recipe simply by knowing the ingredients.

That would be much faster than researching a new potion recipe yourself.

Moreover, deducing a wizard's potion recipe is tantamount to directly provoking that wizard.

Originally, Byron only wanted to buy one set of potion ingredients, because one set of potion ingredients, after processing, could be used for seven or eight potions.

But thinking that he would also try to refine it later, he changed his mind and bought more in case of need.

Seeing that Byron didn't want to say much, Karen didn't dare to delay any longer and began to walk around the shop, constantly grabbing materials.

In just a few minutes, Karen packed all the materials Byron needed and divided them into two portions.

"These materials require a total of twelve magic stones."

Karen trembled as she handed over the packaged materials, her gaze towards Byron now filled with a newfound reverence in addition to her previous mercenary attitude.

Because he knew that Byron, with such qualifications, was someone he could not afford to offend, and was someone his family was trying hard to win over.

Byron took the materials, and the payment card swiped across the card reader in the store, making a crisp "beep" sound that sent a shiver down his spine.

This is before we've even officially started learning how to make potions. The cost of just two basic materials, and not even the purchase of experimental tools, has already been so high.

Potions is truly a money-devouring beast.

Byron paid no attention to Karen's change and left, his mind now preoccupied with concocting potions.

.........

In the laboratory on the second floor of Isolde's Spire, Isolde was currently preparing a potion of deep meditation while explaining the key points to Byron.

After Byron returned, with the help of Colin, he quickly processed the two documents and handed them over to Isolde.

Isolde didn't say much and led Byron directly to the second-floor laboratory.

Only Byron went in; Corinth was left outside.

"Remember the required quantities of ingredients in the recipe, the order in which each ingredient is added, the involvement of mental energy, the techniques..."

"If any step is wrong, the medicinal properties will dissipate, and the potion will become unstable, which means the refining process will fail."

Isolde casually picked up a pinch of powder made from Twilight Grass and dropped it into a transparent beaker burning with a ghostly blue flame, stirring it continuously with pure water.

"You lack experience, so don't be as casual as I am when refining it. You still need to use a balance to measure the ingredients accurately."

As he spoke, Isolde dropped the green particles into the beaker.

"After adding the Radiant Crystal Sand, inject your mental energy into the reaction. This step is to purify the Twilight Grass. Don't use your eyes to see it; use your mental energy to perceive it."

As Isolde spoke, Byron also sensed something unusual in the air; it was the mentor's mental energy beginning to intervene.

Guided by spiritual power, the liquid in the beaker began to separate into layers: the upper layer was turbid gray residue, while the lower layer was a luminous essence.

Isolde casually used a dropper to remove the waste.

"When your mental strength is strong enough, you can directly expel impurities from the liquid through magical vibrations."

"This would make the twilight grass purer, and the potion would also be purer, but I'm demonstrating for you now, so I won't do it that way."

"For you, it's best to stick to using a dropper."

Upon hearing Isolde's words, Byron sensed for the first time that she was different from his other mentors, even though her words remained cold and devoid of emotion.

Byron nodded respectfully, indicating that he understood.

After the twilight grass was purified, Isolde did not stop and continued to purify other materials, while Byron stood aside watching intently.

Each purification process is executed with unparalleled precision, from controlling the timing and stirring rhythm to managing temperature fluctuations and guiding mental energy.

As time slowly passed, the purification of all materials was completed one by one.

At this moment, four cups of liquid, each a different color and purified from different materials, are placed on the cold experimental table.

"Once all the materials are purified, they can be fused together."

Isolde spoke as she continued to work with her hands.

Take out an empty beaker and start pouring the purified materials into it in the correct proportions, stirring constantly.

"At this point, the temperature, proportions, rhythm, and mental strength must all be perfect; none of them can be lacking."

"Especially the spiritual energy used to stabilize these essences; if one is not careful, these essences will be completely ruined."

"The final step is to add the 'Pure Glow Dew,' which is a stabilizer for fusing all the materials."

A drop of pale yellow Pure Radiance Dew fell into the beaker, accompanied by a surge of powerful spiritual energy.

The originally incompatible essences were constantly reorganized amidst the tremors of spiritual energy, and were prevented from exploding by the stabilizing effect of the Pure Radiance Dew.

Finally, the colorful essence transformed into a pure, flawless silvery-white liquid.

Isolde poured the liquid into a test tube and sealed it with a cork.

"Once it has stabilized, pour the potion into a test tube, seal it, and prevent it from evaporating and weakening its potency."

"Alright, that completes one 'Deep Meditation Potion'."

Byron wondered to himself, 'Is everything recorded?'

[All information has been recorded, including changes in drug reaction, temperature changes, and changes in mental strength...]

Just then, Isolde looked at Byron: "Now you try."
