Mana Centrifugal Extraction Method

Professor Alder was as cold as a machine. "If conditions allowed, we should have extracted the blood from a living specimen. A low-temperature, negative-pressure method would have yielded the Stone Crab's blood more effectively."

Using specialized dissection tools, he extracted the pure blood from the Stone Crab's blood-storage organ, divided it into three portions, and drew them into three syringes.

Next, Professor Alder injected the Stone Crab blood from one syringe and a Bloodline Separation Essence Injection Potion into a small glass vial, then handed the vial to Locke.

"Locke, I will now teach you the Magic Centrifugal Extraction Technique. This is knowledge for potion masters. In the Wizarding World, you could never learn it for less than a hundred Magic Stones."

"Now, do as I say. Use your Mana to guide the mixed liquid and create a Mana vortex within it. Only then can the Bloodline Separation Essence Injection Potion combine with the Stone Crab Bloodline and gradually extract the bloodline we need."

Alder said, "The precision of your Mana and your proficiency in manipulating it will directly determine the purity of the bloodline essence extracted."

"This is something I can no longer do."

Alder said regretfully, "The dissection and such from earlier—after enough repeated practice, even an ordinary person can manage them."

"They are merely minor techniques."

"But the Mana Centrifugal Extraction Method is a skill only Wizard Apprentices can master, and only those Wizard Apprentices specializing in Potions. This is the true obstacle."

"We only have three chances."

"But I believe in you. Even if all of them fail, it will not be your fault. After all, there is not a single Wizard Apprentice specializing in Potions on Corfu Island."

Alder spoke calmly. For some reason, in front of Locke, this young Wizard Apprentice, he no longer displayed the madness and recklessness he usually showed before his ordinary students.

Instead, he seemed more like a wise old man, calmly watching death approach him.

Alder even comforted Locke in turn. "Even if I found Tungus, and Tungus agreed to help me, he is only a Second-Class Wizard Apprentice in the Fire Magic branch of the Shaping School. He might not do any better than you."

Alder said to Locke, "On the other hand, you are a Third-Class Wizard Apprentice in the Plant Magic branch of the Life School. You are naturally suited to developing in Potions. And your Mana, for some reason, is calmer than that of ordinary Wizard Apprentices—even calmer than mine. I believe you have a real talent for Potions."

"It is just that old man Tungus failed to see it."

"That was his negligence."

Locke glanced at Alder. "Teacher has three students to guide. He is busy, so it is understandable that he did not notice for a while."

Alder smiled at Locke's defense of Tungus.

"Failing to notice your talent as a wizard in time was my loss."

Locke looked at Alder, not expecting him to treat a fellow wizard like himself this way.

There was not the slightest trace of that mad history professor.

On the contrary, Alder was witty, optimistic, and composed, displaying the bearing of a wizard.

Perhaps, in Professor Alder's heart, he had never regarded the ordinary people of Corfu Island as his own kind.

But it was also possible that Alder simply did not want to embarrass himself before Locke, his newly advanced Wizard Apprentice.

He did not want to completely lose his dignity before someone who was also a Wizard Apprentice.

Following Professor Alder's instructions, Locke gripped the glass vial and merged his Mana into the mixed liquid. Then he rotated his Mana, causing the liquid to spin and form a vortex.

Within the vortex, his Mana guided and vibrated the Bloodline Separation Potion, accelerating its separation of the useful portions of the Stone Crab Bloodline.

Which specific part of the bloodline was to be separated was determined by the Bloodline Separation Essence Extraction Potion—in other words, by the design of that Formal Wizard.

But whether it could truly be extracted, how much could be extracted, and how pure the result would be were all determined by Locke, who was using the Mana Centrifugal Extraction Method.

Professor Alder stared fixedly at the glass vial in Locke's hand. "Much better than I expected."

"Locke, pay attention. What you are doing is the primary work performed by assistant potion wizards."

"If you master this, once you reach the Wizarding World, you could even find work at a wizard shop with this skill."

"Oh no, it failed. You rotated your Mana too quickly. The active ingredients of the two potions did not have time to make deep contact, and the purity was lowered instead."

"It is fine. We still have two portions of materials."

"Quick, begin again."

Yet Locke did not move for a long time. Instead, he stared at the glass vial in his hand and frowned. Based on his estimate, even if he repeated the process two more times with his current grasp of the Mana Centrifugal Extraction Method, he might not succeed.

His way of doing things was that once he decided to do something, he would do it properly. He would not start strong and end weakly; he would see it through from beginning to end.

Moreover, magical resources on Corfu Island were limited, and chances to obtain knowledge for free were rare. If he had an opportunity to master the Mana Centrifugal Extraction Method, he should make the most of it.

I cannot listen to Alder and immediately repeat the process. That will definitely fail, with little difference from the previous attempt. Locke suddenly had an idea. Wait. The core of the Mana Centrifugal Extraction Method lies in the speed of my Mana's rotation and the precision of my Mana.

"So even if I practice with ordinary water, it should barely work."

"Better to treat a dead horse as if it were alive than directly waste the second portion of materials."

Locke remained silent.

Alder asked Locke somewhat nervously, "What is wrong? I believe in you. You can definitely do it. Do not lose heart."

Locke shook his head and explained all his thoughts.

Only then did Alder realize it. "Right, what you said is indeed a last resort."

"It really can improve the success rate."

"Locke... thank you."

Locke shook his head. "It is nothing. Our relationship is merely a transaction."

"It is just that I do not like failure."

"Since I promised you, I will make it happen."

Locke took an empty glass vial from the box and walked outside, while Alder stared blankly at the young Wizard Apprentice's retreating back.

Alder sighed. "Young people truly are different from me."

"It seems that no matter the outcome this time, I must teach him Skull Explosion properly."
