From Hogwarts to Strixhaven

"No...please at least let me play a role!" Cassandra asked, "Soul or future, just take it, but I can't just stand by and watch, at least...let me do something for you...Horcruxes...let me help find Voldemort's Horcruxes!"

Voldemort has seven Horcruxes in total, Ivy remembers them clearly.

The destroyed diary, obtained from Malfoy.

The Ravenclaw diadem hidden in the house of the request and response.

The Gaunt family ring in the old Riddle house, the ring is also inlaid with the resurrection stone, one of the Deathly Hallows. More than a hundred years ago, Ivy had a friendship with Omenis of the Gaunt family, who almost broke up with his family publicly. At that time, Ivy wanted to deal with Lanlock, so he found a time to collect the Deathly Hallows. Unfortunately, he was sealed in the crystal in the end and had no chance to complete this task.

Slytherin's locket, a relic of Voldemort's mother, was swapped by Sirius Black's brother and is now in the hands of the house elf in the Black mansion.

Hufflepuff's gold cup is hidden in the vault of Bellatrix Lestrange, who is now imprisoned in Azkaban, waiting to serve Voldemort again.

Nagini, the blood-cursed orc that Voldemort encountered in the Black Forest of Albania, is one of the only two living Horcruxes.

And the last one, that is, Harry Potter himself, Voldemort's soul fragment is hidden in the lightning scar on his forehead.

Ivy knows the location of all the Horcruxes, so how could she need the help of a first-year witch?

"I have my own arrangements for Voldemort's Horcruxes, you don't have to worry about it. What you need to do now is to work hard to grow up and use a healthy body to cooperate with my magic research. This is your only mission now."

"Cooperate with magic research", this requirement sounds simple, but it is actually extremely dangerous. After all, it was Ivy's first time to be someone else's leader. If he accidentally removed some limbs and wasted one or two lives, it would be normal.

How to transfer his magic power, which is too dangerous for ordinary people, to Cassandra's body and find a perfect balance between efficiency and safety is what Ivy needs to test.

If Cassandra is compared to a container, then the black magic mark on her shoulder is the water inlet valve. When she accidentally used the magic energy explosion before, the switch of the water inlet valve was in her own hands, and she borrowed as much magic power as she needed from Ivy.

But after the two people's oath, the switch of the water inlet valve is now in Ivy's hands. How much magic power Cassandra can get depends on Ivy's mood. Moreover, the difference in strength between the two is too great. If Ivy is not careful, the magic power he transfers may exceed Cassandra's carrying limit and burst her whole body directly. So how to control the amount of magic power to be transferred is exactly where Cassandra needs to cooperate next.

When the switch of the water inlet valve was in Cassandra's hand before, it was equivalent to Ivy accidentally creating a weakness for himself.

The reason is simple. Since Ivy can activate the Dark Mark on Lucius' arm by touching it, there is no reason why other magic masters cannot do this. After all, the Dark Mark on Cassandra's shoulder is derived from the Dark Mark. If a magic master with profound knowledge catches Cassandra, he may drain the magic power in his body through Ivy's mark. Although this possibility is pitifully small, Ivy cannot treat it as non-existent.

Any wizard who aspires to climb the peak of magic should have the quality of caution, otherwise any magic experiment may bring him a catastrophe. More than a hundred years ago, Ivy did this. Studying dark magic is like dancing on ice that may crack at any time. Once you make a mistake, you will fall into the icy abyss and fall to the level of Voldemort.

Even though Ivy is already a master of dark magic, he still fell into the ancient magic secret library under Hogwarts more than a hundred years ago, and the whole person was sealed in crystal for a century.

The lessons of the past are the lessons of the future. What's more, this happened to Ivy himself.

Therefore, he would never leave any loopholes for the enemy to exploit. The mark left on Cassandra's shoulder was indeed a crisis, but danger always coexists with opportunities. Ivy was able to spy on the most essential relationship between the warlock and the master, and to further understand the truth about his own golden finger - the Destruction Grimoire.

"Okay, Cassandra, I shouldn't have revealed so much about the contents of the Horcrux. Now that Voldemort is hiding in the dark, all our actions must be cautious. So to be on the safe side, I will try to protect this memory of yours with magic to prevent someone from secretly spying on your brain." Ivy took out his wand and put the tip of the wand against Cassandra's temple.

"I see..." Cassandra lowered her eyes and nodded, "Will I still keep the impression of the Horcrux?"

"Of course not. Whenever you recall this memory, your brain will tell you that this is a memory about Voldemort's secrets. You must rely on magic to carefully preserve it. You will not know the details of this memory unless you get my permission." The method of blocking the memory is not to prevent Voldemort from snooping, but to prevent Dumbledore and Snape. After all, they are the only two in this school who always use Legilimency to read other people's minds.

Snape was better, at least he only used it on Harry, but Dumbledore was different. He almost regarded this method as the only way to distinguish good from evil. And Cassandra was a Slytherin who deserved vigilance. Who knows, one day he would use Legilimency to greet this little witch.

Ivy's wand spit out a few strands of silver, which floated into Cassandra's brain. In just a few seconds, the magic used to protect memory was completed.

"Miss Volley, the spell you used in class is what I call magic energy explosion. It is a very dangerous spell, both for you and your classmates." Ivy restored Professor Victor's demeanor, while lifting the magic that blocked the classroom, and said in a calm tone, "Three times a day, this is the maximum number of times your body can withstand this magic. If it is not an emergency, I hope you don't use it once."

No mistakes in one song, one post, one content, one book, one bar, one 6, one 9!

"I understand... Professor Victor." After a brief confusion, Cassandra's eyes returned to a clear state.
