The Emerald at Hogwarts

Ada looked at the person who appeared in front of her in surprise. This person was the Slytherin senior sister who sent Ada a letter at night!

Her act of directly casting the spell just now was a bit reckless. If she was given another chance, she would probably do it again and strike first.Everything around the underground classroom made people feel uneasy, and this uneasiness was one of the reasons that prompted her to take action directly.

Why is she here?Why did she bring herself here?Ada thought silently in her heart, holding the wand tightly, always on guard against the other party's movements.

Ada didn't know this senior, and today was the first time the two of them spoke. Before that, Ada had only seen her once in Welfare's support group.The day Foley left school, she was the one who cried the most in the crowd, and those around her called her Eriny.

Ada didn't know at all how she had offended this Erini senior. The only intersection between the two of them was probably seeing off welfare together.

The senior named Erini did not respond to Ada. As she got closer and closer to Ada, the sarcasm on her lips became stronger and stronger. She waved the wand in her hand and cast a blue spell towards her. Ada.

Ada quickly dodged and the spell hit the wall, making a big hole.The flying stone chips made Ada a little embarrassed, but Ada didn't have time to sort it out. She raised her wand and pointed it at the door.

When Eriny walked out of the classroom, Ada chanted the spell again: "Collapse!" The spell flew quickly in the direction pointed by the wand.

The distance between the two people was not far, and the spell came to Erini in an instant. Erini waved her wand and blocked Ada's attack.After blocking the attack, Ereni cast four spells at Ada and started her counterattack.

Ada kept dodging, and the spells that could not be avoided could only be resisted with defensive spells such as [Iron Armor Curse].

As these spells were blocked by Ada, Eriny's face finally had some other expressions, curiosity and resentment on her face.

Is the teaching quality at Hogwarts so high?Can a senior who has not yet graduated be able to perform a silent spell combo?Ada thought to herself.

"Expelliarmus!" Ada yelled, and a bright red light headed straight for Erini.

[Disarming Curse], a spell that seems ordinary but is actually extremely powerful.This is the evaluation given by the system.Ada has always thought so, so Ada also practiced diligently after obtaining this magic spell.

The opponent didn't even have his wand, so naturally he had no choice but to capture him.Few people can cast spells without a wand, and those who can do so will not be hit by your disarming spell.

It is not known exactly who invented this spell. Some people claim that the spell came from Merlin; others say that this spell was once very popular in Madagascar in the [-]th century, but few people used it at that time.

Another more reliable theory is that the spell was invented by Elizabeth Smachlin.Elizabeth also used the [Disarming Curse] to win the duel competition.

It was also after that duel that this spell with disarming and sometimes even knockback effects really spread.

Ada didn't care who invented this spell. She now hoped that her powerful blow could knock away the wand in the opponent's hand. She cast the spell silently four times in a row, which put a lot of pressure on Ada.

Erini, who came from Slytherin, just waved her wand casually, and the powerful [Disarming Curse] was bounced away. She was really sorry for the extremely high evaluation given by the system.

The two people had already sent several spells to each other, causing a lot of noise, but no one came to check in this corridor.This place is like a gladiatorial arena now, and only one person between Ada and Erini can stand and walk out.

Eriny cast the spell silently again, and a faint red light came towards Ada.

"Iron Armor!" Ada quickly raised her wand to resist, and the spell hit the invisible protective shield. However, the wand in her hand threatened to fly out, so Ada could only hold it tighter.

"Soul out of body!" This was the only spell that Erini uttered, one of the unforgivable curses, the Imperius Curse.

Erini, who was originally standing in front of Ada, suddenly appeared behind Ada. Her disarming spell was just a cover, and the Imperius Curse she cast behind Ada was the real purpose.

Hogwarts has been restricted, and Apparition is not allowed here, and Ada did not expect that Eriny would suddenly appear behind her.

This spell from behind hit Ada directly. If it was a killing curse, she would be a good-looking corpse now.

At this moment, Ada's mind went blank. Being attacked by Erini was nothing to worry about. Whether Hogwarts could phantom transfer had anything to do with her. She just felt happy now, extremely happy. Nothing else mattered. It doesn't matter anymore.

The system kept making "ding...ding...ding" sounds in her mind, and Ada, who was deep in happiness, gradually realized that something was wrong. She began to use all her strength to fight against the "happiness" in her mind and not let it go. be affected by them.

Some of the techniques for resisting the Imperius Curse are similar to Occlumency. Ada knows Occlumency, but is not proficient in it. Preventing others from prying into her memories and secrets is the only thing Ada can do.

Occlumency is the first magic given to Ada by the system, but Ada has always passively learned this magic. She can resist Legilimency, but she is still somewhat powerless when facing the Imperius Curse.

If Ada had been practicing Occlumency well, she would not have been affected by the Imperius Curse so easily. In the final analysis, it was still her own shortcomings.

Erini's wand was still pointed at Ada. She continued to deepen her spells and continued to exert influence on Ada. In the end, the one who controlled the heart became the victor.

Seeing that the spell was taking effect, Eriny finally removed her wand. She cast a spell to clear away the damage caused by the two of them. The corridor was restored to its original state, and it was impossible to tell that a fight had occurred here.

Ada heard a command in her head: Follow me.She was still trying to resist, but her body was still controlled by this order, and she followed the voice and followed Erini.

The out-of-body Ada followed Erini dully, and the two left the corridor one after the other.Although other students saw it, everyone didn't think much about it. They were just a little surprised that Gryffindor and Slytherin were mixed together, and they didn't think of such a terrible spell as the Imperius Curse at all.

The two people left the castle all the way, and no one saw them again under the cover of night.

Around eight o'clock, the twins came back after being punished.The two brothers walked into the lounge arm-in-arm, and the twins who didn't see Ada walked up to Angelina.

"Hi, Angelina!" Fred greeted, "Why are you alone, Ada?"

Angelina held her chin in her hands and said gently: "She was called away by Snape. This is the food and note she prepared for you."

The twins took the food trays and happily enjoyed the sandwiches prepared by the house elves. George asked, "When did you leave?"

"In less than half an hour, Snape asked her to go to the underground classroom at eight o'clock." Alia said, while motioning for the two of them to read the note left by Ada.

"Eight o'clock? Why did you choose such a time?" George asked puzzledly.

Fred unfolded the note and it read: Professor Snape asked me to go to the basement at eight o'clock, Ada.

The twins didn't eat quickly at first, but after seeing the note, the two of them started to devour the sandwich, finishing the entire sandwich in three bites.

Angelina and Aaliyah were dumbfounded by Fengjuan Canyun's eating speed. This speed was probably beyond the scope of human beings.

The twins hurried up the stairs back to the dormitory. There was an ink dot on the note. If there was such an ink dot on someone else's note, the twins would not care at all, but Ada was different.

The twins had been learning from Ada's homework. They knew Ada's writing habits very well. They knew that Ada would never leave such a dot unless she did it intentionally.

The twins who returned to the dormitory quickly took out the Marauder's Map. They wanted to see where Ada was. They felt that this was a mark left by Ada to remind them of something.

"I solemnly swear that I will not do good deeds."

Ink lines spread across the parchment, and the twins first looked towards the underground classroom, where Ada would be every time Snape called her away.It's just that not only did the twins not see Ada, they didn't even see Snape. They only saw Mrs. Lorris.

The twins continued to search, and they saw Snape on the fifth floor. After a while, he walked up to the sixth floor, but there was no Esmeralda Drizzt's name next to him.

The twins became more anxious. In order to speed up, they began to divide their work. Fred carefully observed the inside of the castle, while George looked outside the castle.

"I found it here, Ada went to the Forbidden Forest!" George finally found Ada's name, and the little black dot representing Ada was moving towards the Forbidden Forest.

Fred also looked over, and the moment he saw Ada's name, a bad premonition enveloped the two brothers.

"Why is Ada with him? Why did they go to the Forbidden Forest?"
