Dr. Duzem is able to refine the Philosopher's Stone, which is no secret to many wizards of sufficient level. The wandering wizard once sold the Doctor's creations in his bar.

It's just that because Dr. Duzem's method of refining the Philosopher's Stone is considered heretical and cruel in the eyes of many of the Alliance's old-school wizards—and one of the charges he was charged with by the school in the first place—the trade has always been controlled by the organization in a very small market.

Only customers who can provide sufficient 'raw materials' and 'auxiliary materials' will have the opportunity to ask Dr. Duzem to assist in refining a 'Scarlet Sage's Stone through certain families.

Yes, the biggest difference between the Philosopher's Stone refined by Dr. Duzem and the traditional Philosopher's Stone is that the stone he refines is blood-colored instead of the traditional gold. Although there is almost no difference in the use effect, this color defect greatly limits the scope of use of this stone.

No serious white wizard family would use such a bloody, but actually bloody, creation in a sacrificial or magical ritual.

Even so, many powerful wizarding families continued to secretly transport the New World captured aliens to that small courtyard, asking Dr. Duzem to help refine the Philosopher's Stone. After all, in addition to public occasions, there are many private occasions in this world, and there are no taboos in this regard.

Although the Wizarding Alliance and First University are well aware of this, they also turn a blind eye and do not completely ban it.

As long as those families don't use wizards as raw materials, they can barely step outside the red line. As the saying goes, if the water is clear, there will be no fish, and if people are observed, there will be no fugitives. Where there is demand, there will be trade. Rather than letting those wizarding families deal with the more secretive and ruthless dark wizards, it is better to keep this kind of thing within a certain range, and it is safer under the noses of the wizarding alliance and the school. However, every once in a while, the Umno Alliance will arrange for the Trident Sword to sweep the market and confiscate some similar products as a warning.

"Do you have to sacrifice to refine the Philosopher's Stone?" Fei Rui finally couldn't help but ask after the Rat Immortal made a contract with Dr. Duzem, "Is there any other way?"

Dr. Duzem raised his eyebrows in surprise as he looked at the stocky hamster.

"You seem a little more merciful than the legend suggests. He rubbed his fingers, and his fingertips subconsciously touched the scalpel on the table, as if he was curious about Fei Rui's current state: "Could it be that the nameless principal really influenced you?"

Fat Rui snorted, and his chubby face was obviously pulled down.

Dr. Duzem smiled disapprovingly: "If you use the traditional refining method, you naturally don't need to sacrifice so much. But that would require a legendary-level alchemist...... Because in the process of refining, the alchemist needs to communicate the long river of time and many subtle and different dimensions at any time. ”

"But I don't need to. My alchemy relies on the most brilliant and dazzling essences of life, which naturally communicate with countless hidden dimensions and connect the long river of time. The devils have proven this to wizards through countless cases. ”

"Since we have lowered the level of refiners, it is inevitable to improve the quality of 'raw materials'. Equivalent exchange. That's a pretty fair thing to do, isn't it?"

"And at the beginning, I was only at the level of a registered wizard, and the technology I developed could only be based on my ability at that time. ”

"You're still a registered wizard. Fei Rui sighed.

“What a pity。 Dr. Duzem spread his hands and sighed as well.

The rat fairy interrupted the slowly decreasing air pressure in the room at the right time, and complimented: "It is worthy of the wizard that "Wand" originally called 'hope for the future'...... Being able to register at the wizard level surpasses the alchemy skills that many great wizards can't achieve, and I'm afraid it's unique in the entire history of the wizarding world. ”

Dr. Duzem sneered, looked over the windowsill, and looked at the small, gloomy sky outside the courtyard wall: "If this is not the case, how can I have the opportunity to live in this small courtyard in peace?"

There was complete silence in the study.

Now that the cooperation intention has been finalized, the purpose of the two uninvited guests today can be regarded as achieved. The specific details of the cooperation can be discussed slowly in the future.

The rat fairy patted the armrest of the chariot and staggered again, floating off the desk.

Fernando finally got his wish and obtained a few primitive species of corpse-eating beetles from Dr. Duzem. He braided the long hairs on the backs of the insects into strings and tied them up and hung them on their backs, making him look even more bloated than when he first arrived.

As he watched the two rats leave, Dr. Duzem suddenly opened his mouth and asked in a low voice, "You are visiting me so directly...... Aren't you afraid of causing trouble for that little one?"

The little guy he said was naturally Zheng Qing.

However, the reason why Dr. Duzem asked this more was not because he was worried about Zheng Qing's trouble. Compared with this, he was actually more worried about bringing trouble to the young lady of the Jiang family, or the Jiang family in Zhongshan, because of Zheng Qing's troubles.

As one of the few families that has truly supported him for more than 20 years, Dr. Duzem has a good impression of the old lady of the Jiang family and does not want to cause trouble for them.

The two uninvited guests glanced at each other.

The rat fairy narrowed his eyes, as if he were asleep, and let the chariot carry him on his way.

Fei Rui stopped and turned around, and replied angrily, "It's none of your business...... That little bunny is in a lot of trouble with him than you are. Whoever has an accident on this island, he will not have an accident. With that in mind, you might as well spend more time polishing up the 'artificial god' project, so that nothing will go wrong in the future. ”

Dr. Duzem raised an eyebrow, but said nothing, and watched as the two rats burrowed back into the black hole drawn in the corner, and disappeared without a trace in the blink of an eye.

Without the squeaks of rats, the small study soon fell back into silence.

The lights and fireflies in the room seemed to feel the low air pressure in the room, and they all lowered the pressure of the lamps and dimmed the light.

Terry Duzem stood in front of the wall with his hands in his hands, looking up at the words the headmaster had left for him.

Long.

The wooden door of the study opened silently.

The old servant Konstantin stood at the door with a worried face, and he stopped talking.

"Go to sleep right away and leave me alone. Dr. Duzem didn't look back, and waved his hand back.

"Okay, young master. Even though the doctor didn't look back, Konstantin still saluted respectfully, but before leaving, he finally stopped, and said thoughtfully: "Young master, rats are pests. It should have been killed. ”

Dr. Duzem lowered his head, his face submerged in the shadow of the wall.

"Hehe, now I am confined in this dark place, what is the difference between me and a mouse?"

Three heads
