This unique bloodline magic could be described as the most powerful ace up Adrian's sleeve. If used properly, it wasn't impossible to compete against adult wizards, so the priority of practice was much higher than Transfiguration.
Adrian thought this should be an easy task. After all, he'd already released it once successfully, and it was displayed in the magic bar of the system.
But Adrian was stumped when he tried to practice it. He didn't know the spell required to summon Cecilia.
It had been automatically activated because he was in mortal danger. He couldn't restore that original state just to try summoning it, could he?
'Wait, is it related to that...'
Adrian suddenly thought of the faint blue phoenix and what Dumbledore had said before, that some wizards were able to integrate the power of magical creatures into magic and display incredible abilities.
In this way, would his bloodline magic be related to the Patronus Charm? After all, both involved summoning the spirit of an animal, and they had many similarities.
It's just that the unicorn's shadow was more special, and it could also fight through special magical manifestation. Adrian guessed this might be because Cecilia's soul had replaced the Patronus.
With these theories, Adrian immediately went to the library to find books about the Patronus Charm. After a few hours, he successfully raised the Patronus Charm to level one.
"Expecto Patronum!" Adrian couldn't wait to enter the Room of Requirement and waved his wand to test.
A plume of white smoke gushed from the tip of Adrian's wand, and a calm, peaceful mood gradually flowed into his heart.
Although nothing appeared, Adrian's face showed a joyful expression.
Because he was absolutely certain at this moment, there was definitely a connection between his bloodline magic, Unicorn Shadow, and the Patronus Charm!
If it were a normal Patronus Charm, the summoned guardian should be ligth blue, not white.
In the following time, Adrian spared no effort to practice the Patronus Charm, even spending his precious grade points.
It's just that it was the end of the semester, and with no way to answer questions in class, points could only be consumed and not refilled. The more he used, the less remained.
"Only five hundred points left..." Adrian finally missed the kind Professor Dumbledore again. Setting aside other aspects for the moment, he'd always been generous with bonus points.
Dumbledore alone had given him at least two hundred points this semester!
But even this wouldn't change the dilemma Adrian faced now.
Considering he might need to deal with emergencies during vacation, he needed to leave two hundred grade points for emergencies. That meant only three hundred grade points could be used!
Which meant there could only be three hours of accelerated learning or practice time!
"Exchange the experience card." After adjusting his state, Adrian didn't hesitate to start the first accelerated practice.
[100 grade points have been deducted!]
Along with the system's prompt, Adrian felt his brain was much clearer. His control of magic power had also improved to a higher level. Then he waved his wand.
"Expecto Patronum!"
The faint white mist reappeared, floating from the tip of Adrian's wand. It became threadlike, like strands of misty smoke, surrounding him.
The white mist that emerged this time was much more than before.
After practicing for a while, Adrian quickly realized the special feature of the Patronus Charm, it was a kind of profound emotional magic.
The caster needed to mobilize positive emotions and gather this power to successfully summon their Patronus!
Adrian was stuck on this final step!
'If only there were a Dementor to practice with', Adrian thought.
Although he was in the Room of Requirement, Adrian didn't try to use the room's characteristics to create a Dementor.
From earlier experiments, he'd understood the limitation here, it was impossible to manifest living creatures and magical items. The room was more inclined to provide a venue.
For example, it could manifest a dragon farm, but there would be no dragon in it. Or it could manifest a vault, but there would be no gold in it.
There were weapons in an armory, but they were all old antiques from a thousand years ago. There were no magical weapons.
Adrian sighed. His thoughts wavered, and the large amount of white mist finally condensed disappeared without a trace. Adrian quickly stabilized his mind, settled himself, and kept reminiscing about scenes that made him feel happy.
When teasing Peter Pettigrew, when making Professor Quirrell take the fall, when throwing Dungbombs at the Dark Lord...
Memories kept flooding his heart. Adrian's mouth filled with a smile. Blessed with inspiration, he waved his wand gently, and the white mist around him seemed to be drawn toward the center.
A long neighing sound echoed throughout the practice room. Among the white light and shadow, Cecilia's illusory figure appeared in the air, happily circling around Adrian, faintly showing a sense of closeness.
What surprised Adrian most was that Cecilia's pupils were no longer blood red but like blue water waves.
'Is it because of the successful revenge?'
Adrian thought, but before long, Cecilia's shadow turned into white mist and dissipated in the air.
At the same time, the system prompt sounded in his mind.
[Ding!]
[The time limit of the experience card has expired. Do you want to renew it?]
"No, cancel!" Adrian said with a dark expression. Without realizing it, he'd spent three full hours in accelerated practice!
He pulled up the system bar and saw the Patronus Charm was upgraded to level two. Adrian tried to use the Patronus Charm again in his normal state, but the result was still just some white mist, unable to make them condense together.
However, in the system bar, a lot of information about the Unicorn Shadow had been added. Adrian gained some understanding after checking it.
[Blood Magic: Shadow of the Unicorn (Cecilia's Shadow)
Requirement: Patronus Charm Level 4 (Level 2 in Experience Card Mode)
Description: This is special magic that combines blood and soul power. As a soul-body Patronus, Cecilia can ignore most obstacles, and only a few magics can cause damage to it. You can also choose to spend a large amount of magic power to temporarily construct a body for Cecilia so it can temporarily interact with the physical world.
Note: Unless the host dies, when the soul body is defeated by fatal injury, it will not completely die and dissipate. Instead, it will rest within your body until it regains its form.]
"So I've become Cecilia's Horcrux?" Adrian muttered to himself while looking at the last note.
He'd just managed to reactivate it by relying on experience card mode before the Patronus Charm level was raised to level four again.
