The Mysterious Black Cat at Hogwarts

"Listen! Dobby! If I hadn't broken my arm, I would have chosen to strangle you right away. You caused me and Ron to be fired almost, and you also caused my broken right hand."

Harry looked at the elf in front of him angrily.

"Dobby is no longer afraid of death threats. Dobby is often threatened like this at home."

Dobby was blowing his nose sadly on the tattered pillowcase.

"Why are you wearing an old pillowcase?"

Harry looked at the dirty Dobby, whose body was dirty and torn, as if he was covered with a large rag, and couldn't help feeling a little soft-hearted.

"It's a symbol of the house-elves being slaves, and they can only be freed if they are given clothes by their masters."

Dobby seemed to have discovered something, and jumped onto the hospital bed nervously, "Harry Potter, you have to get out of here as soon as possible, something terrible is about to happen in the castle, because history is about to repeat itself."

"Repeat? Did petrification happen before?"

Harry grabbed Dobby, wanting to ask what happened.

Dobby realized that he had slipped his tongue, and kept hitting his head with the Bone Spirit bottle.

"Tell me the truth, Dobby!"

Harry was answered by a puff of smoke, and Dobby had already left here. At this time, there were dense footsteps outside the ward, and Harry hurriedly climbed onto the hospital bed and pretended to be asleep.

"Quickly, put him here, what happened?"

Madame Pomfrey looked sadly at Colin, who was being carried to the hospital bed, his stiff body was stained with blue-gray color, and he was holding a camera in his hand.

"Madame Pomfrey, he has been petrified. After Pomona's mandrake matures, he will be cured smoothly."

After Professor McGonagall comforted her softly, she looked at Dumbledore again, "He still has the camera in his hand, maybe he took a picture of that thing."

Dumbledore picked up the camera in Colin's hand, opened the back cover, and suddenly a puff of smoke burst out, and the negative was reduced to ashes.

"What does that mean, Albus?"

"This means that our students are very dangerous."

"Shall we notify the other faculty?"

"Tell them Hogwarts is no longer safe."

Listening to the tense and serious conversations of the professors, Harry tossed and turned all night, unable to fall asleep.

In the evening of the next day, Harry, who had recovered from his injuries, hurried to the cafeteria. He told Hermione and Ron what happened last night.

"Harry, this means that the Chamber of Secrets has been opened before, and now someone has reopened the Chamber of Secrets."

Hermione looked at the two nervously. After the Quidditch match yesterday, Colin was also petrified in the castle.

The little wizards at the dining table were all full of gloom, and the originally joyful dinner atmosphere was almost covered with a few feet of white cloth.

Before, it was only Mrs. Luo Lisi who was petrified, but now she is a living person. They are all in danger, afraid that they will be the next one.

"Let's go, you two call Draco and continue the confinement tonight, the castle is very dangerous now, you must have some ability to protect yourself."

Macon ate and drank enough, and led the four of them to Macon's hut.

"Today you four will have special training, and I will teach you a new spell."

After Macon finished speaking, the long cat's tail stretched out in front of them. The four of them looked at the cat's tail curiously, and Ron leaned forward with his big face.

"Sudden flash!"

Ah~~~

Ron screamed and covered his eyes, rolling around on the ground.

On Mao Mao's tail, a white light flashed in an instant, almost blinding his eyes.

Harry and Draco rubbed their wet eyes, and it took a while before they recovered their vision. They all turned their heads to look at Hermione, why is there nothing wrong with her?

"You must wear sunglasses when you practice this spell, or you will be like Ron, rolling all over the floor."

Macon funnyly took out four pairs of sunglasses and handed them over to them. From the second he cast the spell, he had already put on the sunglasses for Hermione. Of course she was fine.

The hideous black cat did it on purpose, and Harry, Ron and Draco could only sulk.

"Okay, put on your sunglasses as soon as possible. Before casting this spell, you must notify the surrounding friends. Otherwise, you will not save yourself but harm others. After learning this spell, when you feel something is wrong in the castle, just You can cast it, and then flee the scene quickly, if you don't want to lose your life, you won't be stupid enough to confront each other head-on."

When the four of them heard Macon's explanation, their eyes lit up instantly. This 'sudden light flash' is indeed a very practical spell, which is extremely suitable whether it is for fighting the enemy or escaping for life.

This is a very simple spell, a bit similar to 'Flashing Fluorescence', and half an hour later, the four of them were able to skillfully cast 'Sudden Light Explosion'.

"The two of you are not afraid of being bitten to death by bugs while hiding in the grass, Fred and George, hurry up and roll over."

Macon noticed the two people in the grass early in the morning. They didn't come out, and Maomao didn't mind letting them feed more bugs.

"Macon, the two of us want to do business with you."

The two walked out of the grass in embarrassment, and quickly expressed their intentions.

As soon as Macon heard that they were going to do business, he knew what kind of medicine they were selling in their gourds.

"Okay, but the profit will be seven to you three."

This door-to-door business is not done for nothing.

"Of course, thank you Macon."

Mao Mao handed them a booklet and a pair of sunglasses, and the two happily ran to the castle.

The smart Weasley twins probably will use duplication to form a pair, constantly duplicating the spells and sunglasses in the pamphlet, and selling them. Macon doesn't have to worry about their business acumen at all.

"Okay, you three, continue to practice the Iron Armor Curse without a staff. There is one more method, which is an extra layer of protection. Hurry up and practice."

Macon took out his whip and waved it, and the three of them skillfully took off their robes and coats, and began to practice the spell with their upper bodies naked.

Hermione went back to the hut and continued to study the 'Compound Potion'. This kind of potion is very difficult, and she can't master it now. Now she hides in the girls' bathroom to make the potion during the day, and studies it at night. The materials that need to be added the next day and the method of boiling the medicine.

The three hours of confinement passed quickly, and all five of them looked up at the castle. The whole of Hogwarts began to flicker with intense white light, and the frequency became faster and faster. Finally, the castle turned into an oversized incandescent lamp. Filch's angry howls could be heard from far away.

Macon withdrew his gaze, these two people are really good enough, they have done business across the four colleges so quickly.

Hermione looked thoughtfully at the still glowing castle.

The spell that Macon taught them is obviously aimed at the eyes, so it means that the monsters in the castle must have a pair of distinctive eyes, maybe I can start to investigate from this aspect.

She gave herself a plain mirror before taking out Macon, and she was even more sure of this. A warm feeling continued to rise in her heart. She ran to Macon, hugged Mao Mao's neck, and gnawed on his cheek. The red-faced He Min hurried back to the bedroom.

Macon touched the place where he was gnawed, and looked at the little witch who was going away suspiciously. What stimulated this girl?
