Chapter 075: Breaking the Oblivion Curse

"Then I have to stay at school during the summer vacation!" Catherine grumbled.

"As long as you complete a few main runes and ensure the circulation of the magic array, you will be able to run around." Salazar said with a smile.

"What are the main runes?" Catherine asked eagerly.

Salazar drew their patterns out of thin air and pointed out their locations, and the three of them began to make an attempt. In the end, Catherine was found to be the most efficient, and although Snape's hand was steady, she drew more accurately and with better results.

Salazar was to do it on her own, and although Snape agreed, he still demanded that she have to call herself, just in case, and Catherine naturally nodded in agreement.

After arranging the schedule of tinkering with the forbidden spell, Catherine inquired about the other "secret rooms", she wanted to find a training ground for the seven of them, and Salazar directly conjured up a three-dimensional map for her to choose.

Catherine thought for a while, and chose a secret room located near the Defence Against the Dark Arts classroom, one was about the same distance from the common rooms of Gryffindor and Slytherin, and the other was that if you had any questions, she could immediately find the teacher to ask, but she didn't know if the new professor Dumbledore would hire next year be of acceptable quality.

By the time they had said goodbye to Salazar, it was nearly noon, and Catherine had eaten again before rushing to meet with Ixissius to discuss the twins, for the two men had used the excuse of meeting their "benefactor" when they had broken into Slytherin the previous day.

After Catherine and Ixissiy finished their discussion, they immediately used the dot map to find out the twins' whereabouts, and made it a condition of the contract to keep secret what happened in Slytherin yesterday, much to Fred and George's regret.

Because the twins had been studying the terms of the pact since they separated from Catherine yesterday, completely forgetting about their feat of breaking into the Slytherin common room, they had wanted to wait for the celebration after the signing to make a big splash, but now they had to keep it until they got moldy.

After signing a contract with the twins and paying the start-up capital, Catherine didn't bother to pay attention to the two grumbling guys, and she told the other six that she had found a training place and asked them to meet at the door of the Defence Against the Dark Arts classroom.

When they arrived, Catherine led them to the door, and by the way, told them the secret order to open the door, the "SG group", which was also the name of their small group.

Because of the proximity to the Defence Against the Dark Arts classroom, the infrastructure is already complete, and they only need to clean up and make some decorations.

But this is easy to say, but it is quite troublesome to get it together, and when it is all done and it is already dinner time, Catherine simply decides to hold a small banquet to celebrate the formation of the "SG Group".

Misunderstandings always arise because they don't understand, and when they do, they disappear.

After a few parties, the three Slytherins and the three Gryffindors all realized that each other was not what they thought they were.

Draco, who was always very flashy in appearance, hated nothing more than spending at least half an hour a day dressing himself; Harry, who is the most famous, wants nothing to be unobtrusive; Playboy's Blaise is actually a thoughtful man; Ron, the worst of all, is often able to say something amazing; The ladylike Pansy admires violence the most; And Hermione, who was very aggressive, was always the first to find the key.

When they got to know each other, they suddenly realized that they were not difficult to get along with, and the relationship between the six became kind.

Originally, the SG group was worried that their party would attract the attention of others, but everyone's eyes were almost all attracted to the twins.

Ever since the map was confiscated by Catherine, the twins have begun to scrutinize the entire Hogwarts thoroughly, jumping every window and balcony of the castle, enchanting every statue and portrait they see, and speaking to the empty walls.

During that time, the Gryffindors were worried - the twins, who were always too energetic, were stupid! But the harvest was abundant, and the twins paid the price of entering the infirmary twenty-three times in just one month, in exchange for seven secret rooms and eleven secret passages.

Some of those secret passages lead to the common room of the college, some lead to different floors or classrooms, some lead to the professor's office, and one actually extends to the bottom of the lake, the strange thing is that the lake is blocked by an invisible layer of protection, and it does not seep up at all, I don't know what this secret passage was built for in the first place.

But of all the secret passages, this one leads to the bottom of the lake is the most contributing, where they encounter the mermaid and exchange some of their artwork for some precious materials, and the mermaid invites them to visit the mermaid's quarters, much to Catherine and the twins' eyes.

Time flies, and with the Easter holidays in the blink of an eye, the second year has to start thinking about those third year courses. With the exception of Harry and Ron, the rest of the SG team knew some sort of about the subjects.

Because of the Hunting Party, all four Slytherins had to get a time turner, so they chose almost all of them, except for Divination, where Sybil Trelawney was considered the worst professor in the school, and they preferred the most exclusive Muggle studies to fabricate their own bad luck.

Originally, Catherine was not going to choose, but when she thought of the prophecy she had seen from Dumbledore, she felt that it was better to choose, so that one day Trelawney suddenly made a real prophecy and she missed it because she did not take a divination class.

After seeing Catherine choose all, Hermione made the same choice, which frightened Harry and Ron, Harry wanted to give up potions, and Ron wanted to give up Defence Against the Dark Arts, but the original subject could not be abandoned, and each had to choose two more courses.

In the end, they adopted the method of elimination, first crossing out the ancient magic and arithmetic divination, which were very difficult at first glance, and then removing divination, which is considered to be the worst, and finally leaving for the protection of magical creatures and Muggle research.

Thanks to Slytherin's intelligence, the SG team quickly decided on the course of their choice, so that the rest of Easter was free of worries, and the twins' birthdays spread the joy throughout the castle.

As soon as the Easter break ended, Hermione immediately began to prepare for the final review, Draco was also nervous in order to compete for the first place in the grade, and the rest of the SG group had to go crazy, only Catherine stayed out of it, but she had a lot to do.

"I heard you got an SG group?" During the last Defence Against the Dark Arts class in April, Dumbledore suddenly stopped Catherine at the end of the lesson.

"Yes!" Catherine honestly replied that they were wandering around Dumbledore's makeshift office every day, and it was hard for him to pretend he didn't know.

"Can I join, then?" Dumbledore blinked his blue eyes vigorously, "As a tutor." ”

"Of course!" Catherine smiled brightly and handed him a golden notebook.

Dumbledore took the SG Team address book, and a strange feeling suddenly appeared in his mind that someone had sold him and helped him count the money.

"Professor, do you know how to break the Oblivion Curse?" As soon as she left the Defence Against the Dark Arts classroom, Catherine went straight to Snape.

"The Oblivion Charm does not erase the memory from a person's head, it just arranges an invisible 'barrier' that makes it impossible for people to discover the existence of this memory, so it can be broken with the Dementor Charm." Snape put down his work and stared at Catherine, "I thought you weren't going to know!" ”

"I just don't think it's time to know." Catherine shrugged, "When will it start?" ”

"Weekend!"

On Saturday, they made their first attempt to break the Oblivion Charm, but because Catherine had so many memories, Snape searched for a long time but couldn't find it, and finally had to pause because she was not exhausted.

In order to avoid the after-effects, Catherine took a week's break and did not make a second attempt until the second Saturday of May, this time extracting the disturbing memories first, and Snape finally found a trace.

On the third weekend, Gryffindor's Quidditch match day with Hufflepuff, they made their third attempt, and when Snape followed the trail, he quickly felt the power to resist, which meant that he found the "barrier" that Dumbledore had arranged, and he immediately increased his mana output, and the "barrier" had no time to react and was passed through by him.

Snape saw a gloomy Catherine, sitting in the back seat of a sedan, her eyes glowing with an eerie red light, and the strange familiar sensation sent chills through his heart.

Snape followed Catherine's gaze and saw that she was staring fiercely at the car in front of her, and as he looked over, the sedan suddenly sprang out of control and crashed into a dangerous building on the side of the road.

The red light in Catherine's eyes flashed, and the dangerous building began to collapse, and the falling stones smashed the back seat of the car, and the back seat was completely smashed, and the people inside could not get out at all, and then the car exploded, and the people in the back seat were killed on the spot.

Then, the scene changed, and Snape found Catherine sitting on the bed in her bedroom, thinking about something.

Without warning, the girl suddenly threw the pillow in her hand in the direction of the desk, and at the same time rolled over and rolled out of bed, hiding on the other side of the bed, and the thrown pillow was knocked open as if it had hit something.

In the darkness, ripples rippled where the pillow hit, the air itself trembled, and then, as the disillusionment spell failed, Dumbledore's figure revealed.

With a "whoosh", a short arrow shot from Catherine's position to his head, and Dumbledore hurriedly waved his wand to block it.

"Wait a minute, Miss Prince, I have no ill will." Dumbledore said embarrassedly.

Catherine ignored him completely, and the short arrow continued to shoot at Dumbledore's head.

Dumbledore had no choice but to wave his wand again, this time not only blocking the short arrow, but also directly turning the bed in front of Catherine into nothing.

Catherine was frightened by this phenomenon, and she immediately stepped back quickly, but the attack in her hand did not pause, and Dumbledore could only wave his wand without even having time to speak.
