The Emerald at Hogwarts

The protagonists of these two attacks, Mrs. Norris and Colin Creevey, were both petrified, and Dumbledore said that this kind of petrification was extremely advanced black magic and could not be done by students.Therefore, the only thing that can petrify Mrs. Norris and Colin Creevey is the legendary monster in the chamber of secrets.

Speaking of the ability to turn people to stone, Ada naturally thought of the Gorgon Medusa.Among the many monsters (myths and legends) with the ability to petrify, Medusa is probably the most famous.

According to legend, Medusa has a pair of petrified eyes, and anyone who looks at her will be turned to stone.

Medusa is a Gorgon in ancient Greek mythology and one of the three Gorgon sisters.She was beheaded by Perseus, and the blood dripping from her head fell into the desert and turned into ferocious snakes.

Medusa's head was presented to Athena by Perseus, and Athena embedded Medusa's head in the center of the Aegis (Aegis).

It's just that Medusa only exists in ancient myths and legends, and there can't be gorgon in Hogwarts.Even if she had, she would not surrender to that old monkey in Slytherin, let alone live in a secret room without seeing the light of day.

Ada hopes that she can find some clues at the crime scene to make a profile of the monster in the secret room and delineate a range, so that she can find out from the many magical animals or dark creatures that can only make people... Petrified monster.

But Professor McGonagall did not tell Ada the specific location. There were so many stairs in the castle, and it was impossible for her to find them one by one.Moreover, the staircase where the crime occurred would also be passed by other students. Even if there was something there, it would have been destroyed by the students unintentionally.

But Professor McGonagall was Professor McGonagall, and she was afraid that Ada would get into trouble, so she used the stupidest method to conduct a thorough investigation of the castle.At this time, Ada had better not run around in the castle, so she told Ada some of the situation at the scene.

For example, Colin Creevey went to visit Harry, and for example, he brought his favorite camera with him.

Colin was a photography enthusiast and took his camera with him wherever he went, and that was no different the night he was attacked.When the petrified Colin was discovered, his actions were frozen at the moment he raised the camera to take a picture.

It's just that Colin failed to take a picture of the murderer or monster, let alone a photo. The entire camera was destroyed, and the inside of the camera and the film were melted.

Time has entered December before we know it, and Hogwarts is once again covered in silver, but this year there are no lively students on the playground.

The students were in no mood for fun. They just looked forward to being able to leave school during the holidays or for the murderer to be brought to justice as soon as possible.

It was still some time before the Christmas holidays, and although there had been no further attacks on Colin Creevey, the corridors were still deserted.Everyone is hiding in the dormitory, as if only here can give them a sense of security. Every time they leave the dormitory to go to class, everyone is in groups.

After a Potions class, all the students except Ada quickly left the underground classroom, and Ada was left alone by Snape.This was the first time this school year that she had been left alone with Snape.

Perhaps because of the double blow of the Quidditch Cup and the House Cup, Snape has never found Ada this school year, nor has he caused any trouble for Ada in class.

Of course, this is just Ada's own speculation without any evidence.How could Professor Snape be such a stingy person?Absolutely not.

After all the students in the classroom left, Snape started by asking random questions.He asked: "Why are you wearing glasses? Are you seeing too many things you shouldn't be seeing, or are you wandering around at night again?"

Ada pretended to adjust her glasses and said, "I did see some things I shouldn't have seen. The greasy hair polluted my eyes, so I had to wear glasses for protection."

"Do you want me to give you another set of toiletries for Christmas this year? How about that bird egg shampoo produced by Lockhart?" As if she felt that it was not enough to relieve her anger, Ada added.

Snape's sallow face turned dark as expected, and after hearing the names of shampoo and Lockhart, his face became even more so black that it dripped with ink.In order not to make himself even more angry, Snape could only end the conversation as soon as possible. He bluntly stated the purpose of keeping Ada.

He asked: "I am missing some materials from my personal storage room, the horn of a bicorn and the skin of an African tree snake. Are you planning to prepare a polyjuice potion recently?"

Polyjuice Potion is an extremely complex potion that takes a long time to prepare.This potion can make the user look like another person, exactly the same.

"No, what's the purpose of making such a terrible thing?" Ada said, "Besides, you should have the answer in your mind."

In Ada's opinion, there is nothing special about this potion except that it is time-consuming and unpleasant to drink.Moreover, she was right, Snape already had the answer in his mind, and the Potions Professor just came to her to confirm the answer.

However, Snape preferred that Ada had taken these two materials.

Ada has long been able to prepare polyjuice potion independently, and she can ensure that she will not be poisoned, and she has enough ability to protect herself.But the answer in Snape's mind, whether that person could achieve Ada's level, Snape had no idea at all.

"You'd better be honest and don't wander around the castle." Snape decided to end the conversation between the two. He continued, "If I find out, you will stay in the underground classroom with the crucible for the rest of your life. Bar!"

The Potions Professor was not the first person to warn Ada. After the attack, Professor McGonagall and Dumbledore both gave similar warnings.

"Don't wander around the castle", "put away your curiosity", "focus more on studying", these warnings or concerns, Ada is tired of hearing them, and her ears feel calluses. .

Ada left the dungeon very quickly. Snape did not give her detention, nor did he put her in solitary confinement because she was not big or small.In the current situation of the school, confining students is really a terrible choice.

It was still only the afternoon, and Snape did not let Ada return to the common room alone. Instead, he asked the house elf Winnie to send Ada back, and it was even less likely that he would let Ada come to the underground classroom for confinement at night.

Having a house elf accompany you is the best of both worlds.This not only protects Ada from being left alone, but also keeps an eye on her so that she can return to Gryffindor Tower honestly. Killing two birds with one stone is perfect.

On the way back, Ada and the elf Winnie chatted at times. She also asked the elf some questions about the secret room, but Winnie also failed to give her an answer. She provides helpful clues.

In the next few days, Ada was still at a loss. Instead of finding any new clues, she became entangled in trivial matters.

As early as last year, Lee Jordan had a bag spider as a pet.This bag spider has been acting a little weird lately. It always wants to escape from the box it's in, or it shrinks into a ball as if it's dead.

Lee Jordan was confused. He didn't know what had happened to his pet.In order to find out what happened to his pet, Li Jordan mobilized his friends to help him find a solution.

So, Ada, who had just left the library, returned to the library helplessly and helped Li Jordan search for the habits of spiders.

But with this help, Ada suddenly discovered a strange phenomenon. She had not seen spiders in the castle for a long time. Those spiders entrenched in the corners of the castle seemed to have escaped from the castle overnight.
