At the mention of his bloodline magic, Professor Enriquez became very excited, and began to talk about the definition of "human".

"The wizarding world's definition of 'human' essentially refers to any kind of creature that is intellectually intelligent enough to understand the laws of a magical society and to be able to assume some responsibility for the process of making those laws." Professor Enriquez introduced.

"Fantastic creatures like the Eight-Eyed Spider, the Sphinx, and the Sphinx are also intelligent, and although they have the intelligence to understand the laws of the wizarding society, they are not capable of overcoming their murderous nature, so they cannot bear some responsibility for these laws."

"Why, then, are they intelligent enough to overcome their murderous nature?" Professor Enriquez looked at the students in the audience and said sharply. "It's because of their nature hidden deep in their blood!"

"For example, the Sphinx, it is in their nature to ask questions to others, and they cannot change their habit of committing violence when others answer the wrong puzzle, which poses a great danger to humans. Therefore they are divided into beasts. ”

"Species such as dominatrix and trolls, although they can also be violent and savage by eating raw meat, they can control it through communication. There are some dominatrixes active in Tumbledown Alley, and there are trolls who provide security for wizards and follow the rules of the wizarding world. ”

"Of course, there has been some controversy about dividing them as 'people.'" Professor Enriquez burst out laughing and said to the young wizards in the audience. "Because the Ministry of Magic classifies the dominatrix as 'human,' it makes centaurs and merfolk feel insulted and want to classify themselves as 'beasts.'"

"But you don't seem to have talked about bloodlines yet!" The Ravenclaw boy from before, O'Neill Humbe raised his hand and asked.

"Okay, since you asked, let's go straight to the bloodline magic part." Professor Enriquez nodded and smiled. "Let's take werewolves and vampires as examples."

"I think your parents must have said when you were younger, stay away from werewolves and vampires, right?" The professor asked.

Everyone in the audience nodded, except for the Muggle-born wizard.

"As you know, werewolf and vampire saliva is contagious and can turn another wizard into another werewolf or vampire!" Professor Enriquez said solemnly.

"Here I would like to add a piece of knowledge, if you are really bitten by a werewolf or vampire, mixing silver powder with white fresh and applying it to the wound of the new bite can heal it and save your life. However, after the wound healed, the bitten wizard was left to live as a new species......"

The little wizards shuddered.

"Having said all that, what I want to tell you is that werewolf and vampire infections are a type of bloodline magic!" Professor Enriquez spoke to the point, and his tone unconsciously became elevated.

"Their act of fusing toxins that belong exclusively to werewolves and vampires into the wizard's bloodline can be seen as a modification of the wizard's bloodline with magic. And the transformed wizards have new magical abilities, even if they don't want them! ”

Hearing Professor Enriquez's explanation, Xiwen frowned and took the initiative to raise his hand.

"Do you have any questions, Mr. Rozier?" The professor asked.

"As far as I know, wolfing, as well as vampire infections, are irreversible." Shivin asked, staring into Professor Enriquez's eyes tightly. "I wonder, are these two infections irreversible alone, or are all bloodline magic irreversible?"

"I know what you're trying to ask." The professor glanced at Elciona next to Xiwen and whispered. "In fact, all bloodline magic is irreversible!"

"How can something that has been completely integrated into the bloodline be easily separated?"

"So, how did you break those previous blood curses?" Shiwen asked suspiciously.

"There's never been a way to crack it completely, Mr. Rozier." Professor Enriquez sighed and said to Shivan. "At most, it's just a matter of continuing to integrate other bloodline magic to neutralize, or using other magic to suppress the blood spell in the body."

Xiwen sat down in silence and fell into deep thought.

So, Elciona's blood curse is the equivalent of a vampire virus, which took root and sprouted once it entered the body of the ancestors of the Greengrass family, completely transforming their bloodline, so that the entire family became the bearer of the blood curse?

……

Xiwen had been thinking about the Blood Curse for a long time, not even noticing how the Defence Against the Dark Arts class was over. It wasn't until Elshiona patted him next to him that he finally reacted.

"By the way, did you get a reply from your family about the blood curse?" Shivin asked, looking at Elciona.

"Well, my mom wrote me a letter." Elshiona said with a low mood. "She wanted me to take a leave of absence from school and go back home to work with the therapist."

"Whether it's someone to take care of at home, it's still the most important thing about your body!" Xiwen nodded and said to her. "And when are you going to go home?"

"I don't want to go home." Elciona looked straight at Shiwen and spoke.

Xiwen was stunned for a moment, then looked at her with some seriousness.

"El, the question of the Blood Curse is no small matter! Since you have a well-established mitigation at home, why not go back and stabilize it first? Xiwen said.

"I don't want to be locked up at home, not at all!" Elshiona finally couldn't hold back her wet eyes, and raised her voice to speak. "If you had to choose, would you be willing to live all day long in the midst of all kinds of examinations and bloodline modifications in order to live a few more years?"

Hearing Elciona's cry, Sivan froze in place.

He suddenly remembered his life in his previous life—drinking bitter potions all day long, being tested by doctors every day, and enduring soul pain day after day in order to find a way to overcome the rejection of his soul.

However, there is not only illness in his life, but also the company of his brothers, the care of his teachers, and the satisfaction of secretly learning new knowledge, which has brought him a different feeling in the 20 years of fighting against the disease.

Thinking of this, a smile appeared on the corner of Xiwen's mouth.

"Why do you have to try it first, maybe one day you will suddenly recover?" Xiwen said.

"And the healing process is not as painful as you think, maybe there will be more heartwarming stories to accompany it?"
