Hogwarts: I am the power of purification

[Dear readers, please give me a free five-star review! Please!]

Neville's face turned pale, he lowered his head, tears welled up in his eyes. He knew that his mistake had brought trouble to the academy, but he didn't expect to be punished so severely. Mom and Dad will definitely be disappointed!

Professor McGonagall turned around and said to Sir Cadogan, "Sir, please remember not to let any strangers into the Gryffindor dormitory again!" She also reminded the little wizards to be careful! After that, she turned and left, leaving Neville and the other little wizards with frustrated faces.

Rowling was full of doubts. Why did Neville have such a bad memory? Just as he was lost in thought, he returned to his bedroom. However, as soon as he entered the room, Rowling keenly noticed something unusual.

There was a strange smell in the air! He took out his wand cautiously, opened the Eye of Elements, and scanned the surroundings carefully. Sure enough, in the closet, he sensed the fluctuation of magic power! Rowling would never be wrong, this was the big dog from Diagon Alley - Sirius Black!

Luo Lin calmed down a little, then gently closed the dormitory door and whispered, "Come out, I've seen you."

However, no one responded to him. Rowling couldn't help but feel a little amused, and continued, "Very cautious! As expected of Sirius Black, the man who escaped from Azkaban."

Blake, who was hiding in the closet, was shocked when he heard this. Originally, he just wanted to kill Peter Pettigrew, but he didn't expect to wake up the little wizard by accident!

At that time, it was too late for him to escape, and at that moment he suddenly smelled the scent of the wizard who had fed him in Diagon Alley!

Black knew that the little wizard was a kind person! He had no choice but to hide in his dormitory when he was away. He wanted to wait until he fell asleep and then sneak away, but he was discovered! And his identity was also known!

Sirius rushed out of the closet when he heard this, staring at Rowling fiercely, trying to scare Rowling away with a fierce look and let himself leave. Because once Rowling revealed his whereabouts to the Dementors, he would be in extreme danger.

However, Rowling watched Blake's performance quietly and said fearlessly: "You don't have to pretend anymore. I have no ill will towards you. Now, you can leave freely." Hearing this, Blake stopped pretending to be fierce and returned to his wizard form.

"Why do you want to help me? Aren't you afraid that I will kill you? After all, you should know that I have killed many Muggles before." Black's expressionless face revealed a cold tone!

Rowling looked at Blake, who was in a dishevel and dirty state, and a hint of curiosity flashed in his eyes!

Luo Lin was amused by Blake's poor acting skills: "Haha, I don't care about the grudges between you. Fate tells me that you still have an unfinished mission. After you finish your meal, you can leave on your own."

Luo Lin pretended to be mysterious while speaking, and at the same time took out some cakes from his space ring and floated them in front of Blake. Looking at Blake's skinny appearance, it was estimated that he had not had a full meal for a long time.

Although Blake was starving at this time, he still remained highly alert! He was full of doubts about what Rowling said: "Is there poison in it?"

"Good vigilance. If only Harry were as smart as his godfather! It's a pity there was no poison in it, otherwise you would have died in Diagon Alley!" Rowling said jokingly.

However, when Sirius Black heard this, he was shocked and couldn't help but shouted in a somewhat inappropriate manner: "You already know my identity, and you also know that I am Harry's godfather?"

At this moment, there was a knock on Rowling's dormitory door, and Harry's voice was heard at the same time. Rowling was very confused and didn't understand why Harry came here at this time. He looked at the frightened Black, quickly opened the Dust Song Pot, and put him in it.

Luo Lin walked to the dormitory door, opened it and let the three kids in. "It's so late, why did you suddenly come here?"

"Rowling, we have some theories about what happened. Sirius Black may not really want to kill Harry.

He must have other reasons, but why would he hurt Ron? There are too many people out there and they are talking too much, so we decided to come to you. I hope you can tell us the truth." Hermione explained the purpose of their trip seriously.

Luo Lin scratched his head in embarrassment: "Um... well... I'm not really sure. Too many things happened today, and everyone is tired. Let's go to bed early."

Hermione looked at Rowling's unwillingness to reveal anything and knew that asking further would lead to no result, so she shook her head helplessly and left with Harry and Ron.

After they left, Rowling released Blake! He looked at Rowling in horror and saw that he still had a freshly caught fish in his hand!

Luo Lin looked at Blake speechlessly. He had kept this fish in a pot for viewing! It was just saved like this! "Go!"

Blake looked at Rowling awkwardly, but he quickly escaped from the Gryffindor dormitory without any hesitation.

Harry returned to the dormitory and became more and more confused. He frowned and muttered to himself, "Why did Black suddenly disappear? This is all too strange..."

Suddenly, an idea struck him, and he remembered the Marauder's Map! Maybe he could find Black's trace on the Marauder's Map! Harry suddenly felt like he had found a key to solve the mystery, and he was very excited.

He couldn't wait to take out the Marauder's Map and unfold it for a closer look. However, contrary to his expectations, there was no trace of Sirius Black on the map.

But at this moment, a name that puzzled Harry suddenly appeared on it - Peter Pettigrew! This name was not unfamiliar to Harry, he knew that this person should have died long ago, and he was also his father's good brother.

Harry stared at the name, and a strong curiosity surged in his heart. He wanted to find out why this person who had been dead for many years suddenly appeared on the Marauder's Map. If this was true, then he must know the truth of what happened that year.

Harry decided to find the answer himself. After leaving the dormitory, he did not put on the invisibility cloak, but held his wand, flashing a faint light, and walked towards the name of Peter Pettigrew on the Marauder's Map.

He walked carefully along the corridor, every step full of expectation. But just when he was about to meet Peter's footsteps, he found that there was no one in front of him.

He looked around, muttering to himself, "Is the map invalid?" He continued to search unwillingly, hoping to find some clues. However, no matter how hard Harry tried, he could not find any trace of Peter Pettigrew.
