All things are three at Hogwarts

Allen felt that what he guessed was probably the truth.

Professor Lupine took the Wolfsbane potion and no longer needed to go to the Shrieking Shack to hide from the full moon, so even if this place was exposed, it probably wouldn't matter.

"I thought of a place where they could very well be!" Allen said.

"Where?" Harry and Hermione asked in unison.

"Follow me." Allen glanced at Professor Luping involuntarily and led the way decisively.

This glance made Lupine confused, but everyone couldn't wait to follow Allen, and he followed quickly without saying a word.

Allen and the others soon entered the dark forbidden forest.

It took a lot of effort for Professor McGonagall to restrain her urge to reprimand Alan.

"Harris, it is illegal for you to enter the Forbidden Forest." Professor McGonagall pursed her lips tightly, feeling very unhappy.

"Ah, Professor McGonagall, I have another reason. Just today, the Sirius murder case was re-tried, and he is innocent." Allen replied in a deep voice as he hurried on.

A stone stirred up a thousand waves.

Everyone looked at Allen and couldn't help but slow down.

"You mean, Sirius is innocent?"

"Then who is the murderer?"

"Who betrayed my parents?"

"You helped him."

Except for Professor McGonagall who didn't speak, Professor Lupine, Hermione, Harry and Luna asked four questions at the same time.

Allen told the story of what happened that day.

In the dark forbidden forest, there was the whistling sound caused by the cold wind passing through the trees, and only Allen's voice was left echoing.

"It's unbelievable. How could Scabbers be Peter Pettigrew?" Harry thought what Alan said was ridiculous.

"Why is it impossible?" Alan asked calmly.

"Because...because if Peter Pettigrew was an Animagus, people would know." Hermione answered first.

Allen felt that the girl in front of him was very interesting. She liked to answer all the questions.

"We learned about the Animagus in Professor McGonagall's class. I checked the information when I was doing my homework. The Ministry of Magic has records of wizards who can turn into animals. There is a register showing what animals they can turn into, and Marks and the like..."

Hermione continued, and Alan noticed that Professor McGonagall's usually serious face actually showed a smile.

"I looked up Professor McGonagall in the register. There are only seven Animagus in this century. Peter Pettigrew's name is not on it."

Hermione looked at Allen, their eyes met, and Hermione turned her head again.

"But the Ministry of Magic does not know that there were three unregistered Animagus operating in Hogwarts." The person who answered was not Alan, but Professor Lupin.

His voice was extremely bitter, "Sirius Black, Peter Pettigrew, and of course, Harry, and your father, James Potter."

"My dad too?" Harry was surprised.

"Yes," Lupine said, "there is a method hidden in the Black family that can increase the chance of becoming an Animagus."

Allen's expression became serious. Now, except for the gold coins, all the Black family's collection is in his hands!

"Still, it took them nearly three years to learn. Your dad and Sirius are the brightest students in the school, which is lucky, because Animagus transformations can go horribly wrong."

Harry listened extremely carefully. He loved hearing about his parents' deeds.

"This is one of the reasons why the Ministry of Magic has strict control over the Animagus. Peter needs the full help of James and Sirius. Finally, in the fifth year, they finally mastered it and everyone can transform into one at will. A different animal."

"And Pettigrew's animagus is the rat."

Professor Lupine had a complicated look on his face. If it wasn't for the time when he turned into a werewolf to pass more easily, James and the others would never have thought of learning the Animagus in advance.

"Everyone thought Sirius killed Peter," Lupine beat his head in self-reproach, "I actually believed it too."

The conversation did not continue because the Whomping Willow had arrived.

Lupine understood immediately: "Are they here?"

Allen nodded.

"This Whomping Willow looks so good. It looks much more lively than when I was young!" Lu Ping sighed as he looked at the Whomping Willow that was waving around and having strong attack power.

Professor McGonagall looked at the precious plant in front of her suspiciously. What does this have to do with Ron and Malfoy?

Professor Lupine's wand shot a spell, hitting the scar node of the Whomping Willow.

The crazy Whomping Willow fell silent instantly.

Without the protection of the impenetrable branches, the hole was exposed.

Several people followed Allen and Professor Lupin and walked over.

The closer I got, the more I could smell a disgusting smell in the cold air.

"Is this Whomping Willow rotten?" Professor McGonagall covered her mouth and nose.

"Huh?" Professor Lupine observed the entrance blocked by Professor Snape, "This should be Snape's handiwork."

Professor Lupine unsealed the entrance to the cave, and a stench rose to the sky, causing everyone to cover their noses involuntarily.

Several girls looked a little green in the face.

Allen, who has sensitive senses, was even worse. The stench made his throat tight and he was almost suffocated.

This feeling is like standing in a damp and smelly trash can.

Allen blinked and waved his wand, and in a blink of an eye, several girls and a protective bubble appeared above his head.

Professor McGonagall looked at Allen with approval. The Bubble Curse can avoid unpleasant smells, so it is perfect for this.

Professor Lupine and Harry did the same thing, and a huge bubble appeared above their heads.

Professor Lupin and Harry walked into the cave first, followed by the others.

After walking for less than a minute, Professor Lupin and Harry suddenly stopped.

Harry felt something sticky soak through his pants.

Harry tried to move a few steps, but it was difficult to keep his balance on his feet.

He had just taken a few steps when he heard something crunching under his feet.

"Lumos!" Professor Lupine's wand glowed.

When Allen saw the situation in the tunnel clearly, he immediately wanted to pull Luna and Hermione away from here.

But it was too late, everyone was stunned by the sight in front of them.

"Well, I think, Professor McGonagall, it would be better for you to go out and wait." Professor Lupine said.

Professor McGonagall nodded, with an incredulous look on her face, and retreated with Hermione and Luna.

Allen thought for a while, did not move forward, and retreated.

Please forgive me, but the friendship between him and Ron and Malfoy has not yet reached a point where he is willing to go to such a disgusting place for them.
