Chinese students at Hogwarts.

The hand print on the Dementor's cloak is very clear. Judging from the proportions, the fingers are slender and the palm shape is perfect.

It just doesn't look too big.

Zhang Xiao's eyes became subtle, and he didn't know what to say for a moment.

Isn't this a coincidence?

Who knows if a dementor came in the carriage or the one he slapped in Azkaban?

The Dementors apparently noticed this too.

It instinctively wanted to roar and call for its companions, but it suddenly remembered that day, and the 'very delicious food' in front of it suddenly jumped up and slapped itself.

The relatives and friends who came after hearing the news were also beaten, which was quite miserable.

It hurts, it hurts so much! Being hit by the Patron Saint's spell can only be called expulsion. Dementors hate Patron Saints, and the light of powerful Patron Saints can burn them.

But the damage caused by the large sinuses is unmatched by the Patronus Charm. This is the first time that a dementor has been beaten physically!

The Dementor stood there, wanting to scream but not daring to scream, wanting to leave but reluctant to part with a train of delicious food. He felt particularly desolate.

This strange behavior was obviously noticed by the little wizards, and the screams of Malfoy, Ron and Hermione slowly stopped.

They watched as the tall figure of the Dementor gradually shrank back. The originally tall body seemed to be a little bent, and it looked like - scared?

His eyes even stayed on the Dementor's hood, the obvious slap mark.

"Zhang, that slap mark on its hood -" Malfoy asked quietly.

"Ah, it should have been me. Last time I went to Azkaban with Professor Dumbledore."

Was it really you who beat me? Malfoy, Ron and Hermione didn't know what to say for a moment.

This is a dementor!

Harry recovered from the painful pain that seemed to tighten in his stomach.

The cries and screams of women seemed to be echoing in his ears.

Is this a dementor?

Harry shook his head vigorously to free himself from the fear, and raised his wand almost instinctively:

"ExpectoPatronum!"

Dazzling stars burst out from the tip of Harry's wand like morning light.

A deer with big antlers walked gracefully out of the silver light.

It lowered its head and charged towards the Dementor in front of it. The silver light emitted by the Patronus dispelled the negative influence caused by the Dementor.

The Dementor quickly backed away. This patron saint was unexpectedly powerful, especially the 'delicious food' that could slap in the face. It seemed that it could summon a more powerful patron saint.

The entire carriage seemed to come alive again. Right in front of the train, a jumping silver honey badger rushed out of the prefect's box and drove away the dementors in the train.

"It's Cedric!"

Ron shouted excitedly, Cedric's home was not far from Ron's home, and he had been here as a guest during the summer vacation. It was at that time that Cedric revealed that he had successfully summoned the Patronus.

Harry's stag lowered its head, pushed its huge antlers forward, and ran forward.

It emitted a strong silver glow that dispersed all the shadows, and the lights inside the train came on again.

More and more students figured out what was going on.

"Patronus Charm!"

"Physical Guardian God!"

"There are people who can cast the Patronus Charm, and there are two of them!"

Similar shouts came and went in the carriage, and soon the carriage was filled with excited cheers and thunderous applause.

Harry listened to other people's comments, and even though he was always very resistant to other people's praise, he couldn't help but smile.

"Harry, an excellent patronus."

A hoarse voice sounded behind them, and Professor Lupine finally woke up. He inserted the wand in his hand back and stared at the stag running amok in the train, as if he was missing something.

"Professor Lupin."

Harry suddenly became cautious. Facing his father's friend, his reason told him that he should get closer, but the unfamiliar feeling made him only say hello politely.

"Sirius must have told you everything? I knew that guy couldn't hide what he said."

A gentle smile appeared on Lupine's tired face, he patted Harry's shoulder, squeezed it hard, and said with great understanding:

"It's okay, just be yourself."

Zhang Xiao has focused all his attention outside since Harry and Cedric summoned the Patronus.

At this moment, he was staring seriously at the roof of the train, his eyes seemed to penetrate the partition and saw the rainy night outside.

"You are Zhang, right? Dumbledore and Sirius often mentioned you to me, and I have also read about your deeds in the newspapers -"

Lu Ping looked at Zhang Xiao who was staring out the window, and his next words turned into questions:

“Zhang—what’s wrong?”

Zhang Xiao's face became more solemn and he said softly: "Professor, I'm afraid the trouble caused by the dementors is far from over."

At this moment, the cold feeling that had just subsided came again, even more intense than the first time.

Just as Zhang Xiao had felt before, there were a large number of Dementors hovering outside the train. The train, which was invigorated by the Patronus Charm, was now full of happiness and joy.

This is an almost irresistible temptation for Dementors.

Lu Ping's face was quite ugly. He quickly walked to the window and opened it. The whining cold wind mixed with the cold raindrops poured in from the window.

The little wizards couldn't help but shiver and hugged their arms tightly.

Through the light of lightning, they finally discovered a terrifying fact.

A large number of Dementors have gathered outside the train. These terrifying monsters are hovering in the sky, swooping and flying over the top of the train from time to time, sucking in greedily.

"Damn it! Why are there so many dementors!

Are all the dementors in Azkaban here? "

Lu Ping cursed in a low voice. He thought for a moment and said quickly:

"Harry, you use your Patronus Charm to protect this place. I have to find the driver and ask the kid who can use the Patronus Charm to protect the front half of the carriage.

We have to hurry, or else the Dementors will suck everyone into idiots! "

"Well, let me try to see if I can disperse them. We really need to get the train moving quickly." Zhang Xiao nodded and agreed.

Lupine gave him a surprised look, dispelling them?

The greater the number of these dementors, the harder it will be to dispel them. Facing the negative impact of hundreds of dementors, it is already very rare to be able to raise a wand to resist.

Let alone dispersing them.

Even so, Lupine still decided to believe what Dumbledore told him, and he nodded.

Zhang Xiao pulled the upper edge of the window, exerted force with both arms, and rolled onto the top of the train as if on a swing.

Seeing that Zhang Xiao had left, Lu Ping picked up his magic wand and ran towards the front of the car. He could still hear him shouting:
