Hearing her teacher's words Beatrice couldn't help but still frown a little, feeling as if for some reason, something was off, but no matter how much Beatrice thought about it, she could not figure out the cause.
"Come with me," said Selena as she suddenly began walking in a certain direction, stopping at a particular empty space inside of the large hall, with nothing inside of it.
Suddenly, an unconscious middle-aged man flew over Beatrice's head, before landing in a corner of the empty space.
"Stretch out your right hand," said Selena as she looked at her disciple, still with a smile on her face.
Although she felt somewhat uncertain about her teacher's desires, Beatrice still obliged, stretching out her right hand towards her.
Without any warning, a knife appeared in Selena's hands, as she then suddenly cut open Beatrice's palm, allowing blood to fall into a bowl that suddenly appeared below it.
As Selena had made a deep cut, even after a minute, the blood still kept flowing into the bowl, as Beatrice's face become paler and paler.
But right at that moment, the wound in Beatrice's palm suddenly began healing at a rapid pace, and although she did not notice it, at this moment, the middle-aged man laying on the ground looked slightly older than before.
After a few moments, Beatrice's hand was fully healed, at the same time, the feeling of weakness that she had felt, caused by the loss of blood had disappeared as well.
Because of how much blood Beatrice had shed, at this moment, even the large bowl was also halfway full when it flew toward her teacher.
Seeing this, Selena smiled, before ruthlessly slashing her own palm open, letting blood flow into the bowl.
Unlike with Beatrice, where she was quite conservative with the cut, Selena did not have any mercy on herself, causing blood to pour into the bowl at an even faster pace.
As she looked at her teacher, Beatrice instinctually knew something.
"I really cannot escape," thought Beatrice as she watched the bowl rapidly fill up with her teacher's blood, becoming full in under thirty seconds.
At this moment, the wound on Selena's hand suddenly began healing at a rapid pace, causing the middle-aged man in the corner of the room to suddenly begin aging rapidly.
In only a few moments, it seemed as though the middle-aged man had lived several more decades, becoming old in an instant.
But even so, this did not stop Selena from taking more and more vitality from him, using it to heal the wound on her palm, after all, as an Offical Mage, Selena required much more vitality to fully heal, unlike Beatrice.
Rather thankfully for the former middle-aged man, even after Selena's hand was fully healed, he did not wake up, and as such, did not feel any pain in the slightest.
'The Dark Syphoning spell,' thought Beatrice, knowing what her teacher had just done.
As the Dark Healing spell required vitality for it to function, and as such, was nearly useless in healing oneself, the Dark Syphoning Spell was created as a way to steal vitality for it to be used in various ways, mainly through the Dark Healing spell.
But although this spell seemed simple, this was in fact a Rank 1 spell, one which Beatrice would very much struggle to learn before becoming an Official Mage, if she could even learn it at all.
While Beatrice was still in her thought the blood in the large bowl suddenly began separating into two parts.
The first part flew towards the ground, forming a circle with a large number of patterns on it, while the other part suddenly flew into a certain heart that appeared next to Selena.
"Walk in the circle," said Selena as she looked at Beatrice with a smile on her face, causing the latter to suddenly walk toward the circle.
Although she did not know much about the nature of the blood circle in front of her, Beatrice managed to recognize certain patterns, which she had also encountered in some spell diagrams.
But even so, Beatrice still stepped into the circle, causing something to suddenly float in front of her face.
"Eat it," said Selena as she stared at Beatrice, causing the latter to pick up the floating heart into her hands, staring at it nervously.
'Hopefully, this ritual is not too bad,' thought Beatrice before opening her mouth and taking a bite out of the human heart she had taken out of a young boy only a few moments ago.
After taking that bite, rather surprisingly, Beatrice did not feel the sensation she had expected.
Feeling the extremely tender meat suddenly melt in her mouth, a weird feeling couldn't help but emerge in Beatrice's mind.
'Since when did hearts taste like this?' thought Beatrice as she unconsciously took another bite, and a last one, fully devouring the human heart.
Unlike the hearts which Beatrice had eaten when she was young and slightly more insane, which were chewy and made you want to vomit, this heart could definitely be compared to the best food she had ever eaten in her life.
But as Beatrice was thinking about this, she couldn't help but unconsciously touch her neck, feeling the price for this meal.
Beatrice did not need to see it, as the moment it appeared, the blood-red mark on her neck was extremely clear in Beatrice's mind.
After temporarily sorting out her thoughts Beatrice couldn't help but turn to her teacher, having a weird another weird feeling emerge inside of her.
Beatrice looked at her teacher for a few moments before closing her eyes, but even so, without using any spells, Beatrice could still very clearly sense her teacher's location, no matter how far the two of them became of one another.
Of course, Beatrice knew that this connection had a price, allowing her teacher to sense her location as well.
Not only that, but Beatrice suspected that this mark may have had some other, more hidden uses.
