"Boom---!!!"

Suddenly, it was as if a bomb had exploded inside the cauldron.

A blinding blood-red light mixed with raging blue arcs burst from the mouth of the cauldron, and a shockwave mixed with the ultimate smell of blood, sulfur, charred remains, rust, and destructive thunder instantly swept across the entire lab.

The sturdy lab table made a sound of being overwhelmed, the surrounding bottles and jars shook violently, and several glass containers nearby shattered with a bang.

A wave of energy spread out, sufficient to harm weaker lives.

Duke naturally was not affected; yellow sand appeared automatically to block the spreading energy wave and the fragments from the exploding lab equipment for him.

The special silver cauldron's surface was covered with scorched marks and tiny cracks, with most parts already shattered and unusable.

Inside the cauldron remained only some smoldering, charcoal-like residue, emitting a peculiar smell of burnt and bloody mix.

The expensive magic potion materials, worth nearly ten thousand Level 1 Magic Stones, completely vanished in the attempt.

Failure is normal, and Duke didn't expect to succeed on the first try; Blood of War is incredibly complex, with many violent energy surges during the refining process.

Even a slight oversight could cause the entire refining process to fail.

Moreover, without sufficient refining experience, one could easily make mistakes on small details.

He slowly closed his eyes, and every detail of the first refining, every energy wave, every mind impact, replayed and analyzed rapidly in his mind.

"Again." Duke was not discouraged but began preparing for the next refining attempt.

...

Three days later.

[Blood of War: Level 1 (1/30)]

In front of Duke, inside a brand-new silver cauldron, lay the blood-red solution, emitting a pungent smell.

Although it looked unappealing, this was indeed the successfully refined Blood of War magic potion.

In the past few days, Duke had failed four times in a row, and only succeeded in refining Blood of War on the fifth attempt.

He hadn't rested these days and had been immersed in the lab, now feeling a bit of mental fatigue, taking a breath involuntarily.

This batch of Blood of War by Duke can be divided into many portions, each worth over tens of thousands of Magic Stones.

In practical application, each portion of Blood of War is further diluted, then distributed to those slave creatures to use.

This way, even weaker slave creatures can consume Blood of War without facing the consequence of exploding due to its overly powerful energy.

After dividing the Blood of War into test tubes and cleaning the lab, Duke finally took a rare break.

The refining of Blood of War is more time-consuming than other magic potions, so the growth in proficiency will necessarily be slow.

Yet Duke plans to invest some time in this, as mastering Blood of War to its highest level and acquiring its traits will yield huge rewards.

Of course, there is a risk, as the trait outcome might not be favorable, thus not providing substantial benefits.

Nonetheless, it must be tried; otherwise, the advantage of having the Skill Tree would be wasted.

Even if the trait lacks significant commercial value, Duke can still gain a wealth of knowledge feedback through the trait extraction ability, making it worthwhile.

Each trait extraction absorbs vast amounts of information from the deconstructed traits—such is invaluable wealth.

Duke didn't rush into continuing the Blood of War refining, instead taking out a piece of parchment to review the entire refining process, jotting down some points requiring attention.

He comprehensively reviewed the entire refining flow, fully aware of every detail that requires attention at each stage.

In the following days, Duke used up the remaining five sets of Blood of War magic potion materials, successfully four times and failing once.

He packed all of the Blood of War and prepared to sell them to the Giant Rock Commerce Association.

Currently, these Blood of War are only of ordinary quality, so they can be sold according to market price.

After contacting Harrison, the other party was quite surprised: "You've mastered the refining of Blood of War so quickly?"

Harrison was aware of how troublesome it is to refine such a magic potion, posing a significant challenge to most alchemists.

In fact, not many Level 1 Mages can refine Blood of War; typically, only those like Lady Hela, with very high talent, can master its refining proficiently.

Generally, alchemists face high failure rates when refining Blood of War and are likely to incur losses.

Due to the high cost of trial and error, many are reluctant to spend money trying, leading to fewer alchemists mastering Blood of War.

After selling this batch of Blood of War, Duke earned over five hundred thousand Level 1 Magic Stones from the Giant Rock Commerce Association, pulling in a profit over four hundred thousand.

Primarily, the failure rate is excessive; out of ten materials, only five succeeded.

However, with the improvement in proficiency, subsequent refinement becomes increasingly familiar, naturally boosting success rates.

After handling this batch of Blood of War, Duke then took out the research results on Sun Resilience Potion and headed once again to the Arcane Master Association in Harbor City.

He contacted Caroline of Arcane Master Association in advance; upon arrival, she was already waiting at the door.

The Arcane Master Association places great importance on Arcane Masters, and currently, only Caroline is responsible for liaising with Duke.

Once Duke's Arcane Master level rises, there will even be an entire team to serve him, and in need of resources, he won't even have to lift a finger, just letting the Arcane Master Association know.

Mages have an unimaginable pursuit of knowledge and truth, and they maintain utmost respect for scholars.

Duke followed Caroline into the Arcane Master Association, presenting his research results.

This stack of parchment is evidently more complex than previous content, revealing its complexity.

Caroline earnestly took these materials, asked Duke a few questions, then recorded the corresponding information on the dossier containing the materials.

The material will then be submitted for review; Duke only needs to wait.

Currently, Duke still needs to personally deliver materials; after becoming a Level 1 Arcanist, he won't need to run on his own, as Caroline would indeed take care of it for him.

"Mr. Duke, I'll process the review progress of this material for you, striving to complete it and provide you with a result as swiftly as possible," Caroline said quite professionally.

"Thank you, Miss Caroline," Duke nodded in response.
