The process of researching protective witchcraft artifacts went much more smoothly than Jeming anticipated.

Perhaps it’s due to the continuous optimization of the brain and soul brought about by the "Body Refining Technique" and his now profound foundation in the knowledge reserve of two major systems, in less than a month, a finished product was already placed on his laboratory table.

It was a simple in design, sleek metal bracelet.

The color was muted, and it felt cold to the touch.

In the center of the bracelet was inlaid a transparent crystal stone the size of a pigeon egg, within which was sealed a slowly flowing, softly glowing golden liquid, like liquid sunlight bound inside.

Jeming admired his work with satisfaction.

To solve the core issues of energy consumption and wear in isolation-type witchcraft artifacts, he took a different path, not adopting the traditional sustained power supply model, but instead borrowed the protective principles of the Lifebound Magical Treasure "Profound Gang Red Dust Barrier" and deeply coupled it with the Rune Technology of the Wizard World.

The protective mechanism of this bracelet is similar to the Profound Gang Red Dust Barrier, using a combination of "triggered response" and "consumable defense" technology.

Its core principle is: the Composite Rune Array inscribed within the bracelet will drive the central clump of golden liquid—essentially, the refined Liquid Refined Gold—to release the power containing the concepts of "eternity" and "stability", forming an extremely resilient Mental Barrier.

Under normal conditions, this barrier can exist for a long time, but once it detects a force attempting to distort the mind, it can forcibly neutralize or deflect the intrusion by consuming the refined gold.

Simply put, it resists attacks by consuming specific "protective materials".

Additionally, Jeming employed advanced Alchemy Techniques to physically and energetically separate the main structure of the bracelet from the consumable protective materials.

The design of the bracelet’s main body is precise and sturdy, theoretically capable of long-term use.

And the actual consumable is that lump of high-purity refined Liquid Refined Gold stored within it, specially purified.

This means that as long as the specially-made liquid refined gold solution is continuously filled into the bracelet, its isolation and protection ability can be maintained almost indefinitely!

Of course, this is merely theoretical "infinity".

Restricted by the volume of the bracelet itself and the material load limit, the total amount of protective materials filled at once is fixed, its defense having a theoretical upper limit.

Based on Jeming’s calculations and limited testing, this bracelet should be able to resist illusion attacks equivalent to the strength of Sixth Level Sorcery for a long time.

Against Seventh Level Sorcery, it can sustain for a considerable amount of time, but if faced with Eighth Level power, it might only withstand one or two impacts.

However, even when facing such intensity of illusion attacks, this bracelet is sufficient to serve as an extremely sensitive high-risk warning device—when the user discovers that the golden liquid reserve within the bracelet is being consumed at an unprecedented rate, they can immediately realize they are under a much more terrifying attack than expected and thus take extreme countermeasures.

As for the choice of protective materials, Jeming ultimately settled on refined gold.

This conceptual material is originally renowned for its properties of "inertia", "eternity", and "corrosion resistance" (including energy and mental corrosion), making it an excellent carrier against mind-distorting forces.

More importantly, compared to other rare materials of the same level, the basic cost of refined gold is relatively lower.

Of course, Jeming did not use ordinary refined gold ingots.

He processed it into a near-liquid, high-purity conceptual material—Liquid Refined Gold—using a complex conceptual extraction process provided by the Great Dao Book Pavilion.

This form of refined gold can better exert its "eternal" properties, significantly increasing its resistance efficiency against mental pollution, with evaluations that reach the standards of Sixth Level high-grade materials.

But for Jeming, the refining process is merely a matter of consuming some time and energy, the entire batch completion being possible using the automatic factory in his internal space, with no high technical threshold involved.

"Exceptional effectiveness and... enormous subsequent consumption." Jeming looked at that captivating golden liquid in the center of the bracelet, a satisfied smile on his face.

If he weren’t afraid of seeming too deliberately suspicious, he would practically want to give away the bracelet’s main body for free and rely on the exclusive supply of this Liquid Refined Gold for long-term profits.

After confirming that the performance of the witchcraft artifact was stable and correct, Jeming contacted Blake.

When the communication was connected, after a brief exchange, Jeming directly presented the finished product and detailed the usage method.

He emphasized its "eternal isolation" mechanism and the need to periodically replenish the "Liquid Refined Gold".

"...Therefore, the total price for this ’Heart Barrier Bracelet’, including the liquid refined gold pre-filled enough to maintain ten years of normal use under medium-intensity interference, is set at one million military merits," Jeming quoted the price.

Without waiting for Blake’s reaction, Jeming continued, "However, since we’re old classmates, it’s our first cooperation, and you’re willing to provide combat data, I can give you a discount—five hundred thousand military merits."

Blake on the other end of the screen was visibly stunned for a moment.

He didn’t expect Jeming’s efficiency to be so high, producing a finished product in less than a month.

Listening to Jeming’s introduction and the transmitted partial performance parameters, this witchcraft artifact’s design concept was novel, and its protective principle sounded quite reliable.

Especially the warning function, it is very practical in unknown environments.

Though the subsequent need to continually purchase Liquid Refined Gold adds ongoing costs, as a Fourth Level Wizard, this expense is still within a bearable range.

However, Jeming’s excessively fast manufacturing speed evoked again a sliver of doubt in Blake’s heart.

This efficiency is... too high.

For excellent custom witchcraft artifacts, which Alchemy Master does not deliberate repeatedly, testing for months or even years to complete?

However, Blake did not show any of this on his face, instead displaying a grateful and delighted smile: "Jeming, your efficiency is truly astonishing! This price is also very reasonable, thank you so much!"

He signed the trade contract with Jeming straightforwardly, then transferred the five hundred thousand military merits. 𝒻𝑟ℯℯ𝑤𝑒𝑏𝑛𝘰𝓋𝑒𝓁.𝒸𝑜𝘮

He then provided Jeming with the spatial coordinates and received the dark bracelet floating in the teleportation light beam.

After ending the communication, Blake rubbed the bracelet, feeling the cold touch and sensing the faint yet steady energy fluctuations from the golden liquid inside.

"The effect sounds good... but ultimately it’s a new design untested in actual combat, and the production cycle was too short..."

He pondered for a moment before finally making a decision.

With a thought, he pulled up the communication list again, his gaze falling on the names of several other reputable Alchemy Masters.

"Perhaps... better wait and see what these masters have to say." He sighed softly.

...

...

A year later.

Blake, wearing the bracelet, crossed the Teleportation Array with a gloomy expression.

His process of customizing witchcraft artifacts was quite unsuccessful.

The appointment slots with those few Alchemy Masters he was in contact with were mostly already full, and although he finally found someone, the time was too tight, and the other party was also unable to help.

Ultimately, Blake could only hastily purchase a few off-the-shelf mental protective witchcraft artifacts and boarded the Ship Plane.
