In the upper part of Stranshoa, a large white tower stands out.

The tower, with no windows visible from the outside, stands alone and stands out in a low research institute, but the tower is rarely entered, silent and deserted.

The sunlight cast a huge shadow on the tower, and Rockfield looked up at the giant white tower and walked briskly into it.

This is the highest temple that necromancers yearn for, and it is also the headquarters of the Immortal Throne, the White Tatra Hill, which itself is a huge alchemical life that condenses the essence of the necromancy and alchemy, and the destination of Rockfield's trip is the top of the White Tower.

Taking the elevator, Rockfield soon arrived at the office at the top of the giant tower, where the view is good, and the windows that surround the room can see both the endless plain and the glacier where the winter resides, and the beauty and cruelty of the world are mixed together to present a magnificent picture.

In the huge office, there was only one desk, and when Rockfield arrived, several mages were reporting at their desks.

“...... In the above four countries, the influence of 'blood rock' is the most serious, and even involves high-class nobles and some mages, the source of these 'blood rocks' is very hidden, and what we have seized is only some lower families. ”

"The production process of this medicine is not complicated, but it is difficult to purify, and these 'blood rocks' we found are obviously divided into two kinds, one is shoddy and defective, which is widely circulated among the general public, and the existence of this inferior blood rock is often found in bars, restaurants, and some private parties."

"The other is extremely pure, it requires at least a third-level alchemy workshop to manufacture, and the price of this high-quality blood rock is also very expensive, and it is usually only accessible to lord-level nobles, and the medicinal effect and dependence are also stronger."

"The makers of the blood rock seem to have deliberately created this situation, using cheap and inferior blood rock to attract new people, screening out the rich and powerful, and then selling high-quality ones to them, so that the average sheriff can only catch a few retail investors who are not important."

After the end of their report, the people who listened to the report spoke.

"Regarding the matter of 'Blood Rock', you two will continue to investigate, and if necessary, you can use extraordinary means to report to the High Council in a timely manner......

Behind the desk, Charles. Preston was clasping his hands in front of him, blocking the bottom half of his face.

"You can go down first, as there may be a mage involved in this matter, you must be cautious and stay safe."

Hearing this, the two mages saluted and retreated, passed by Rockfield, and bowed slightly to him.

"Good afternoon, Lord Rockfield."

Rockfield nodded in acknowledgment, and strode forward to the desk of his teacher, Lord Preston.

"Sherlock and John, both of them are battle mages, and the blood rock is already so serious?"

Instead of directly stating his purpose, Rockfield became interested in their conversation.

Blood Rock is a kind of illegal drug that can cause mental addiction in various countries in recent months, usually mixed with tobacco, after smoking Blood Rock, people's spirits will become trance-like, fluttering, extremely excited, but when the effect of the drug has passed, it will immediately become sluggish.

In addition, if you stop smoking, it will cause a strong physiological reaction, and you may even act to harm your own body.

The drug circulated among the population and was not taken seriously at first, until last month, when a viscount died suddenly after an overdose on blood rocks, that the Magical Guild really took this new drug seriously.

"In serious countries, blood rock has even become a commodity in official circulation, with great signs of replacing ordinary currency, and they even let children smoke these drugs, which is really scum."

Preston lamented that theoretically, the Magical Guild could not interfere in the governance of other countries at will, so although they had warned those in power of those countries when they were aware of the danger of the blood rock, I am afraid that in the land where the blood rock spread, these people in power were no longer able to control it.

The forced intervention of the Magic Association can only help some of the victims, and the strategy of the blood rock maker itself makes it elusive, and after several blows, although a large number of blood rocks have been confiscated and many practitioners have been arrested, the real source is still unknown.

"Don't talk about that, Javier, what is the situation with you today, and the research has progressed?"

Preston shook his head, and then asked, Preston instructed Rockfield to study the use of radioactive materials to treat that kind of lesion, but there has been no substantial progress in this time, and it seems that there is still a long way to go to cure those diseases.

"No, actually, I'm here for this paper."

Rockfield presented Reiner's paper.

"Reiner. Ian Gray ......"

Preston didn't expect to see Reiner's name again so soon, and it was on an academic paper.

"This paper presents a theory of species inheritance, and I think I should show you, teacher."

Directly explained, Rockfield explained his reasons for bothering Preston.

"Interesting, I didn't expect that young man to actually have research on necromancy."

Preston picked up the paper and flipped through it carefully, his expression sometimes solemn, sometimes focused, as if he had to comprehend every word thoroughly before turning the next page.

After a long time, Preston let out a sigh.

"If this theory is confirmed, I am afraid it will be the last straw that crushes the pure-blood faction."

A large part of the reason why the twenty-seven pure-blood factions have been able to maintain their current status is that their clansmen can advance faster than others, thus occupying a part of the mainstream mages, and at the same time, their secret methods of fusing bloodlines are also worth exploring for the study of magical creatures.

But if the bloodline factor really exists, then the secrets of the pure-blood sect that were shrouded in mystery in the past will probably be stripped naked and thrown into the sun, which will be a huge blow to the status of the pure-blood faction.

The pure-bloods' long and trial-and-error process of transforming their bloodlines is superior to the theoretically backed modern methods of magic.

"Actually, teacher, I already have some clues about the blood factor."

Rockfield told his teacher about the paper he had read about chromosomes, and he did not hide it, because Preston, as an authority on necromancy, must have read that paper as well, and perhaps had already connected it when Rockfield narrated it.

“...... If it can be verified that the bloodline factor does exist on the chromosomes, then the fusion of the bloodline is no longer the patent of the bloodline mage, and at the same time, some incurable diseases that have been suffered since birth may also find new ways to cure the ......."

After listening to his student's story, Preston muttered to himself that he hadn't been so excited in years as he was today, and was eager to go to the lab to test these conjectures.

But before that, Preston knew they had one more thing to do.

"I have to write a letter to Reiner. Ian Gray, the Immortal Throne owes him another favor. ”
