It's only evening now, but the outside world is like late at night, and the flickering black shadows are passing by the window, and the carriage is becoming more and more depressing...

Harry's thugs froze, breaking out in a cold sweat.

Hermione was also a little scared, and she suddenly remembered that the new Defence Against the Dark Arts professor was in the carriage, and hurriedly turned her head to look over.

Lupin was not pretending to be asleep, he had already stood up, his eyes looked out of the window, noticed the dark shadows gathered around, and said to Ivan helplessly.

"You're too reckless, Hals, there are a lot of Dementors here, and they hold grudges!"

"They're not the only ones who hold grudges..."Ivan tossed the potions book aside, and as the Dementors gathered more and more, all that was left to his mind was the things that made him angry and painful.

"What do you want to do?" Lupin frowned.

"Let them get away, of course!" Ivan's tone was sharp.

He had previously forcibly released the Guardian of the Gods under pressure from the Dementors, causing his proficiency to skyrocket. The Patronus Charm had been upgraded from level four to five, which meant that mood swings would not affect his use of bloodline magic.

The large number of Dementors who had been hovering in the sky were a little helpless, they could feel the delicious food below, and they had just killed a member of their kind, and now they were furious, and the rules of the Ministry of Magic were no longer in order.

A large number of dementors rushed down from the air, the black pressure was overwhelming, the temperature around them was getting lower and lower, and there was a faint cry outside, obviously a little wizard couldn't bear the pressure and collapsed...

One of the Dementors at the front came straight through the window, but before he could take a breath, he was catapulted out of the way by a white light.

"Divine Guard!"

As Ivan recited the incantation, more white mist drifted out, forming a huge light shield that enveloped the entire carriage, and continued to spread outwards for a moment.

Several Dementors collided directly with the light mask, causing ripples, and the light mask composed of white mist was very solid, without the slightest sign of breaking, but the white mist corroded the body of the Dementor.

The Dementors were not afraid, they gathered more and more, and the white fog with relatively scattered power was a little unsupportable.

Lupin clutched his wand, and if Ivan couldn't hold on, he would help, even though he didn't want to be seen as his Patronus...

Ron and Hermione both stared nervously at the sky, fearing that the Dementors would tear through the light shield and rush towards them.

Ivan waved his wand unhurriedly, and nearly half of the white mist broke away from the mask and gathered together, accompanied by a hissing sound, and the dementors who swooped down scattered in terror...

Although there are a large number of Dementors who come to patrol, Ivan's Unicorn Shadow is not an ordinary Patronus, it is like a natural enemy for Dementors, once it is hit or trampled on by a unicorn, it will be knocked into a cloud of black fog and dissipate into the air...

Ivan drove these Dementors away from the Hogwarts train, and he didn't mean to deliberately kill them, after all, these Dementors were employees of the Ministry of Magic, and if they killed too much, they would be slapping the Ministry of Magic in the face.

A white light appeared in the sky, chasing the wonders of a large group of Dementors running around.

However, because I can't see it clearly through the white mask, I can only see a little outline... This is also something that Ivan did on purpose.

Hermione, who saw this scene, breathed a sigh of relief, and Lupin said with emotion.

"I didn't expect you to summon your own Patronus at this age."

Ivan's God-calling guards were more powerful than he had imagined, and Lupin estimated that while he could also banish these Dementors, it would never be as easy as Ivan's.

"It's not a lot of hard magic to learn." Ivan shook his head.

Harry learned the magic in his third year and succeeded in summoning a Patronus.

In fifth grade, many of the students in Harry's DA did this after a period of practice.

Suddenly, Ron's eager voice rang out in the carriage.

"Harry, what's wrong with you? Harry? ”

Ivan turned his head to look over, only to find that Harry, who was sitting in the opposite corner, had lost consciousness and fallen to the side, his face looking very pale.

Lupin's face also changed slightly, and after stepping forward to check it, he slowly breathed a sigh of relief, and said to Hermione and Ron, who were worried.

"Harry, there's nothing wrong with him, he's just temporarily unconscious under the influence of the Dementors, just let him rest for a while..."

"But why didn't we pass out?" Hermione asked curiously, Harry didn't think she was that fragile.

"Dementors suck away pleasure and make people recall all the painful things, so those who have a painful experience are under more stress when dealing with Dementors than the average person...", Ivan explained.

"Yes, as Hals said, there's no shame in Harry's coma because he's been through something terrible..."Lupin sighed as he looked at Harry's painful appearance in his sleep.

Ron nodded, and Hermione glanced thoughtfully at Ivan, remembering Ivan's overreaction to the Dementors.

At this moment, there was a rush of footsteps outside the door,

After a while, two middle-aged wizards in uniform appeared in front of the door with unkind faces, and the leader glanced in the carriage, his eyes stayed on Lupin's body, and asked.

"Who released the Patronus just now?"

"Two Aurors, it's me!" Ivan looked at the two of them fearlessly, and he knew that the two wizards should be the accompanying Aurors, the Dementors who were responsible for supervising the enforcement of the law.

After all, Dementors are evil and chaotic creatures, and it is impossible for the Ministry of Magic not to send someone to restrain them and prevent them from getting out of control.

"You?" The stocky Auror Captain looked at Ivan in disbelief, and then at Lupin with a strange expression.

He really couldn't believe that it was a thirteen or fourteen-year-old wizard who had banished so many Dementors, and immediately wondered if Lupin wanted to escape the blame and deliberately let a little wizard take responsibility.

In the strange eyes of the two, Lupin smiled helplessly, this was really not what he did.

Ivan didn't reply, waving his wand to bring up a white mist, and a calm and peaceful aura surged into everyone's hearts.

The two Aurors looked at the little wizard in front of them, and although Ivan didn't show his patronus, it was enough to have this hand...
