From Hogwarts to Strixhaven.

Chapter 108 Blocking Memory
"No...please at least let me play a role!" Cassandra begged, "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 had seven Horcruxes in total, and Ivy remembered them clearly.

The destroyed diary, obtained from Malfoy.

Also hidden in the Ask and Answer room is the Ravenclaw diadem.

The Gaunt family ring in the Riddle old house, with the Resurrection Stone, one of the Deathly Hallows, inlaid on the ring. More than a hundred years ago, Ivy had a friendship with Omenis of the Gaunt family, who almost broke with his family publicly. At that time, Ivy wanted to deal with Lanlock, so he would find 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 Black's old house.

The Hufflepuff cup, hidden in the vault of Bellatrix Lestrange, who now lies in Azkaban, awaiting her return to Voldemort's service.

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 is Harry Potter himself, the fragment of Voldemort's soul is hidden in the lightning scar on his forehead.

Ivy knew the locations of all the Horcruxes, so why would 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" sounds simple, but it is actually very dangerous. After all, it was Ivy's first time to be someone else's clan leader. If he accidentally broke off some limbs or wasted one or two lives, it would be normal.

How to transfer his magic power, which is too dangerous for ordinary people, into 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. She could borrow as much magic power as she needed from Ivy.

But after the two of them made a vow, the switch of the water inlet valve was now in Ivy's hands. How much magic power Cassandra could obtain depended on Ivy's mood. Moreover, the difference in their strength was too great. If Ivy wasn't careful, the magic power he sent might exceed Cassandra's carrying limit and burst her. So how to control the amount of magic power sent was exactly what Cassandra needed to cooperate with next.

When the switch of the water inlet valve was in Cassandra's hand, Ivy had inadvertently created a weakness for herself. The reason was simple. Since Ivy could activate the Dark Mark on Lucius' arm by touching it, there was no reason why other magic masters could not do it. After all, the Dark Mark on Cassandra's shoulder was derived from the Dark Mark. If a magic master with profound knowledge caught Cassandra, he might be able to drain the magic power in her body through Ivy's mark. Although this possibility was pitifully small, Ivy could not ignore it.

Any wizard who aspires to climb the peak of magic should be cautious, otherwise any magic experiment may bring him disaster. Ivy did this more than a hundred years ago. Studying black 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 into the level of Voldemort.

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

The past is a lesson for the future. Moreover, this incident 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 peek into the most essential relationship between the magician and the master, and to further understand the truth about his own golden finger - the Destruction Grimoire.

"Okay, Cassandra, I shouldn't have told you so much about the Horcruxes. 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 anyone from secretly snooping into your brain." Ivy took out his wand and placed the tip of the wand against Cassandra's temple.

"I see..." Cassandra lowered her eyes and nodded, "Then will I still keep my impression of the Horcruxes?"

"Of course not. Whenever you recall this memory, your brain will tell you that this is a memory about Voldemort's secrets. It must be carefully preserved with magic. You will not know the details of this memory unless I allow it." 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 if he would use Legilimency on this little witch one day.

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

"Ms. 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 regained his Professor Victor's demeanor and lifted the magic that blocked the classroom while speaking 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 even once."

"I understand... Professor Victor." After a brief moment of confusion, Cassandra's eyes returned to clarity.
