All things are three at Hogwarts

"It finally appeared!" Allen's wand was aimed at it silently.

But this move was not noticeable, because everyone else also pointed their fluorescent wands at the uninvited guest, trying to see what it looked like.

The hand disappeared immediately, suddenly retracted into the folds of the black cloak.

"What is this?" Hermione grabbed Alan's arm in horror.

"Dementor!" As soon as Allen pointed his wand at the dementor, Hermione pulled his arm off without knowing it.

The dementor took a long, slow breath, making a gurgling sound in its throat, as if it was sucking in more than just the surrounding air.

A biting chill swept over them.

Harry, who was next to Alan, rolled his eyes upwards and fell off his seat, twitching all over.

Hermione screamed and knelt down to check on Harry.

Ginny was shaking like crazy, so scared that she couldn't breathe.

Ron huddled up and muttered: "Don't come over, don't come over!"

Neville stood stunned and bewildered.

The dementor stood at the door, slowly turning his head and looking left and right, as if looking for something.

As Alan tried to think of things that made him happy, his patronus phoenix erupted from the tip of his wand and the dementors rushed over.

The dementor immediately turned around and walked away leisurely.

Allen quickly distributed the chocolates he had prepared before to everyone in the cubicle.

"Eat it, it will help!" Allen stuffed a piece of it into his mouth.

A wave of heat rushed to the tips of his toes and fingers, and his whole body felt warm.

A scream full of terror suddenly sounded from the car outside the compartment.

Alan gave all the chocolates in his hand to Neville and ran out.

Hermione was sitting on her knees next to Harry, but when she saw Alan's actions, she looked confused.

"Penello!" Alan shouted.

In the train corridor, countless dementors were moving in and out of different compartments.

In the darkness, their tall, hazy figures looked particularly scary.

Penello was surrounded by four dementors.

Allen's patron saint phoenix flew out of the wand again and rushed towards the dementors beside Penello.

The Dementors seemed particularly afraid of this Phoenix Guardian and retreated far away.

Allen hurried to Penello's side and stuffed a piece of chocolate into her mouth.

"The dementors of Azkaban! How come they are here?" Penello grabbed Allen's hand and felt the power return to his body.

Allen did not answer her, but looked warily at the dementors that were gradually gathering.

Perhaps Allen's two consecutive patronus spells angered them; perhaps he wanted to see who could cast such a powerful spell; perhaps a magical creature like the phoenix was too rare as a patron saint...

The dementors all rushed towards Allen, and they were all covered in darkness.

"Ellen!" Penello shuddered. She felt that the car suddenly became very cold, as if a biting cold wind was blowing.

"Don't be afraid, Penello! Think of happy things!" Allen clenched the wand with a firm expression.

A chill penetrated his heart, and the fog began to blur his vision.

"Go away! None of us are hiding Sirius Black under our robes. Come on."

A voice came from behind Allen.

It's Professor Lupine!

He also held the wand in his hand and scolded the dementors sternly.

However, the dementors were unmoved. They seemed determined to investigate Allen and the others carefully.

"Calling the Guardians!" Lupine cast a spell decisively, and a silver object came out of his wand and shot towards the dementors.

It was a wolf, strong and tall, and looked very powerful.

The dementors retreated, but some still refused to leave.

The fog in front of Allen's eyes cleared.

"Calling the Guardian!" Allen recited the Patronus Charm again, and cast the Patronus Charm continuously in a short period of time, which made him feel a little tired.

Penello stared obsessively at Allen's Phoenix Patronus, which spread its huge wings and hovered in the carriage.

Wherever the phoenix passed, the dementors fled.

Penello also tried casting the Patronus Charm.

She knew the spell but had never successfully cast it.

"Call God, call God," Penello gritted his teeth and insisted, "Call God to protect us!"

A wisp of silver thread floated out from Penello's wand, hanging in front of her like mist.

This is a formless guardian angel.

Penello held Allen's hand, as if infinite courage was injected into her body, as if the warm current she felt when eating chocolate had expanded countless times!

Something emerged from the tip of her wand, no longer a shapeless cloud, but a gleaming silver animal.

It flew away from them nimbly, followed by the silver wolf and the phoenix, and rushed towards the large group of dementors...

The three patron saints work together in perfect harmony and are incredibly powerful.

The dementors retreated, dispersed, and disappeared into the darkness...

They are gone.

Penelo's patron saint turned around and ran slowly towards Penelo and Allen through the train corridor where calm had returned.

They finally saw it clearly - a fox!

A cute, flexible and smooth little fox!

"As cunning as a fox, this is very Penello!" Allen joked with a smile.

Penello looked at his patron saint infatuatedly, feeling extremely happy and satisfied in his heart, but he refused to be outdone: "What about you, the phoenix who loves stinky beauty?"

She stretched out her hand to touch the shining silver fox, but it disappeared.

"What a good patron saint!" Professor Lupine looked at Penello and Allen in admiration.

He looked at Allen with a particularly solemn expression.

"Professor, what's wrong with me?" Allen asked with a raised eyebrow.

"At your age, it is really extraordinary to be able to successfully cast the Patronus Charm! Moreover," Professor Lupine paused and said, "As far as I know, there is only one person who can use a magical creature as a Patronus, Dumbledore. He is a phoenix just like you!"

"Perhaps you will do great things in the future. Dumbledore is the greatest white wizard in history." Lupine looked at Allen carefully and came to the conclusion.

Penello on the side nodded repeatedly, showing an expression of admiration and a little pride!

She never doubted Allen's future. There is no doubt that Alan is the most outstanding student that Hogwarts has ever produced.

Allen's expression was a little subtle.

This was not the first time Allen heard this sentence. Ollivander also said this when he bought the wand.

Although Ollivander and Professor Lupin had different starting points, they reached the same conclusion.

"Thank you, Professor! I will take your encouragement as motivation to move forward." Allen blinked and smiled gently.
