Chapter 145: Irreversible Magic

Mentioning the blood magic he excelled at, Professor Enrichez grew quite excited and launched into a passionate and eloquent introduction regarding how a "human" is defined.

"In the definition of the magical world, a 'human' essentially refers to any creature with sufficient intelligence to understand the laws of magical society and bear partial responsibility in the process of formulating those laws," Professor Enrichez explained.

"As for magical creatures possessing comparable intelligence such as Acromantulas, Sphinxes, and Manticore, while they have enough intellect to comprehend the laws of magical society, they lack the capacity to overcome their inherently savage nature, and thus cannot shoulder any responsibility for those laws."

"Then, why is it that despite having sufficiently high intelligence, they cannot overcome their brutal nature?" Professor Enrichez looked at the students below the podium and said sharply, "It is because of the instincts deeply hidden within their bloodlines!"

"Take the Sphinx for example: posing riddles to others is part of their nature, and they cannot change the behavioral habit of turning to violence when someone answers a puzzle incorrectly, posing a tremendous danger to humans. Therefore, they are classified as beasts."

"As for species like hags and trolls, although they also tend to exhibit violent tendencies and barbaric behaviors such as eating raw meat, they can be controlled through communication. Right now, there are some hags active in Knockturn Alley, and some trolls provide security work for wizards, abiding by the rules of the wizarding world."

"Of course, classifying them as 'humans' has also sparked some controversy," Professor Enrichez suddenly laughed and told the young wizards below. "Because the Ministry of Magic classified hags as 'humans,' centaurs and merpeople felt insulted and requested to be categorized as 'beasts.'"

"However, you haven't seemed to mention the matter of bloodline yet!" Oner Honby, the Ravenclaw boy from earlier, raised his hand and asked.

"Very well, since you asked, let us dive straight into the part about blood magic," Professor Enrichez nodded, smiling as he said. "Let us use werewolves and vampires as examples."

"I suppose your parents must have told you all when you were young to stay away from werewolves and vampires, correct?" the professor asked.

Except for the Muggle-born young wizards, everyone else in the audience nodded.

"Then I presume you also know that the saliva of werewolves and vampires is infectious, capable of turning other wizards into another werewolf or vampire!" Professor Enrichez said solemnly.

"Let me add a piece of knowledge here: if someone is truly bitten by a werewolf or a vampire, applying a mixture of silver powder and dittany to the freshly bitten wound can heal it, thereby saving their life. However, once the wound has healed, the bitten wizard can only live on as a new species..."

The young wizards wore expressions of shuddering chill.

"Having said all this, what I want to tell you is that the transmission of werewolves and vampires belongs to a form of blood magic!" Reaching the crucial point, Professor Enrichez's tone involuntarily grew higher.

"Their act of fusing the toxins exclusive to werewolves and vampires into a wizard's bloodline can be viewed as a magical modification of the wizard's bloodline. And the modified wizard gains new magical abilities—even if these are abilities they never wished to have!"

Hearing Professor Enrichez's explanation, Shivan frowned and proactively raised his hand.

"Do you have a question, Mr. Rozier?" the professor asked.

"As far as I know, lycanthropy and vampire infection are irreversible," Shivan stared intently into Professor Enrichez's eyes and asked. "I would like to know, is it only these two types of infection that are irreversible, or is all blood magic irreversible?"

"I know what you want to ask," the professor glanced at Elshione sitting next to Shivan and said softly, "In fact, all blood magic is irreversible!"

"Things that have completely integrated into the bloodline—how could they ever be easily separated?"

"Then, how were those past blood curses broken?" Shivan asked with a puzzled expression.

"There has never been a way to completely break them, Mr. Rozier," Professor Enrichez sighed and told Shivan, "At most, it is merely continuing to integrate other blood magic for neutralization, or using other magic to suppress the blood curse within the body."

Shivan sat down in silence, plunging into deep thought.

Does that mean Elshione's blood curse is equivalent to a vampire virus? Once it entered the body of the Greengrass family's ancestor, it took root and sprouted, completely altering their bloodline, thereby turning the entire family into transmitters of the blood curse?

...

Shivan kept pondering the issue of the blood curse, not even noticing when the Defense Against the Dark Arts class ended. It wasn't until Elshione patted him on the arm that he finally snapped back to reality.

"By the way, regarding the blood curse, has your family written back to you?" Shivan looked at Elshione and asked.

"Mm, my mother wrote me a letter," Elshione said with a rather low and dejected mood. "She wants me to suspend my studies and return home to recuperate under the care of healers."

"It's good to have people taking care of you at home; your health is the most important thing after all!" Shivan nodded and said to her, "Then when are you planning to go home?"

"I don't want to go home," Elshione looked straight into Shivan's eyes and said.

Shivan was slightly stunned, then looked at her with a somewhat solemn expression.

"El, the issue of a blood curse is no small matter! Since your family has a thorough method of alleviation, why not go back first and get it stabilized?" Shivan said.

"I don't want to be locked up at home, not at all!" Elshione finally couldn't hold back as her eyes grew moist, and she raised her voice. "If it were you, would you be willing to spend your days surrounded by various examinations and bloodline modifications just to live a few more years?"

Hearing Elshione's tearful complaint, Shivan froze in place.

He suddenly recalled the life he led in his previous existence—in order to find a way to overcome the rejection of his soul, he spent his days drinking bitter potions, undergoing daily examinations by physicians, and enduring day after day of pain originating from his very soul.

Yet his life was not solely defined by illness; the companionship of his fellow apprentices, the care of his master, and the satisfaction of secretly acquiring new knowledge were constants by his side, bringing a different kind of meaning to those twenty years of battling disease.

Thinking of this, a faint smile appeared at the corners of Shivan's mouth.

"No matter what, you should at least try receiving treatment first; who knows, perhaps one day you might suddenly recover completely?" Shivan said.

"Besides, the process of medical treatment isn't as full of suffering as you imagine. Perhaps there will be many more warm and tender stories accompanying you along the way."
