HP: The Root of Everything - The Magician

Conclusion 4: Dementors are immune to physical attacks, but can be touched by intangible and intangible 'pure magic'.

[Conclusion 5: Wizard spells can harm Dementors, but their 'immunity' to spells far surpasses that of any known magical creature; they can repair any spell damage in an extremely short time.]

Conclusion Six: Dementors possess intelligence roughly equivalent to that of a 5-year-old human.

[Conclusion Seven: The Dementor groups are not without leaders; each group has a commander.] These seven conclusions are the information that Shake obtained from her battle with the Dementors in the sky outside the magic train.

Xia Ke enveloped herself in natural magic without any spell effects, which effectively blocked the Dementors' emotion-absorbing ability that ignored defenses. However, she could only effectively block it, not completely ignore it.

For example, if a Dementor absorbs 10 units of emotion, then with this pure magic shield, their absorption rate becomes 5 units.

Furthermore, because the absorption amount is weakened by the defense, when a person is being drained by a Dementor, they are no longer in a frozen state like their soul leaving their body, and can retreat or fight back.

Xia Ke stared intently at the Dementor that had drained a trace of her emotions from the sky, and then began her pursuit. She was determined to reclaim that trace of emotion that she had carefully protected in her heart.

From the seven conclusions, Shakke learned that Dementors are essentially impossible to kill because they have no soul of their own, and even the Avada Kedavra curse cannot destroy them.

Therefore, Xia Ke could only catch up with the target Dementor, then use natural magic to create a cage, sucking the locked Dementor into the magical cage.

Seeing that one of their kind had been captured by a human for the first time in history, the Dementors stopped attacking Shake and floated like ghosts, following the magic train at a distance toward Hogwarts.

......

On the magic train.

A Dementor broke through the train's protective magic and began searching the carriages one by one for the criminal who had escaped from Azkaban—'Sirius Black'.

This Dementor cleverly uses public office for private purposes. Every time it opens a carriage, it randomly selects a lucky person and then opens its abyss-black mouth to suck up their happy emotions to fill its belly.

Finally, after checking and using it one by one, it arrived at the carriage of Teach Carr and others.

As the Dementors drew near, a chilling cold that penetrated their skin and reached their very bones spread through Harry and Ron's bodies. Hermione was not spared either; she too shivered and snuggled closer to Teach, secretly trying to warm herself.

But this behavior drew a frown from her teacher, Teach: "Hermione, I've taught you, and your Uncle Cori Bab has personally shown you how to handle dangerous situations."

"Do you think this sudden, bone-chilling cold is normal?"

Reprimanded, Hermione suddenly realized what was happening. She quickly stood up, took out her wizard wand, and began to channel magic into the pseudo-magic circuits on her left arm. Her eyes were fixed on the carriage door, ready to defend herself at any moment.

Ron was puzzled when he saw Hermione suddenly pull out her wand: [Who is she trying to attack?]

Although Harry was also confused, seeing Hermione's serious expression as if facing a formidable enemy, he also took out his wand and pointed it at the carriage door.

Before long, a tall, elusive black shadow appeared outside the glass of the carriage door. With the appearance of the shadow, the biting cold intensified, causing frost to form on the ground and in the air.

Upon seeing this, Hermione didn't let the shadowy figure open the car door; instead, she launched a magical attack: "Thunder Explosion."

"Flames blazing."

Hermione first controlled the amount of magic output from her wand, then used a thunderous explosion to blast a small hole in the carriage window so she could see what the dark figure outside was.

Then flames roared, shooting out through the holes in the glass, aimed directly at the dark shadow whose shape was indistinct.

Although she didn't know, that didn't stop Hermione from considering the shadowy figure a dangerous enemy.

Teach taught Hermione that once someone is identified as an enemy, one should not hesitate to launch an attack to eliminate them.

Hermione was surprised when she found that the two spells had no effect, but she immediately began to think carefully and then cast a glowing spell, which was the opposite of darkness.

Hermione's wand glowed brightly, and then she quickly drew a chakra circle on the glass of the carriage door with her left hand.

'High-temperature training formation'

'Closed Training Formation'

'An abnormal isolation training formation'.

Under the combined effect of these three training formations, the ice crystals and coldness inside the carriage were dispelled by the high temperature.

The formation of a closed and abnormal isolation barrier kept the shadowy Dementor outside.

Harry stared in disbelief at Hermione, who had just completed all the offensive and defensive magic measures. A surge of amazement, astonishment, and admiration welled up inside him, making this academically challenged man, who was known as a prophetic savior, feel utterly ashamed.

A sense of insignificance and humility arose in Harry's heart in front of Hermione.

Ron didn't think as much as Harry did. He just stared at Hermione with his mouth agape, completely dumbfounded: "Wow, this... is absolutely awesome!"

Teach gave a nod of approval to her disciple Hermione, who was turning around, and then focused her gaze on the carriage door, where the Dementors were trying to force their way in.

At the same time, the man who had been sleeping inside his coat also woke up.

After being shocked by Hermione's high level of combat awareness and unconventional alchemical skills, he took out his wand and looked at the Dementor's shadow reflected in the glass. A tiny, rice-grain-sized 'holy' glow appeared on his wand, ready to expand and launch at any moment.

With Hermione on high alert, a few minutes later, a cracking sound came from the carriage door.

It wasn't the door that cracked, but the transmutation circle Hermione had drawn on it.

This scene made Detic frown deeply.

With the training array destroyed and the carriage door opened, the Dementors' skeletal claws reached out. Only then did Hermione truly see what her enemy was: [A Dementor...].

Under the blind gaze of the Dementors, Harry and Ron, who knew nothing of Dementors, felt as if they had fallen into an ice cellar of eternal cold. The chill went straight to their souls, instantly freezing even the thought of escaping from their minds.

Hermione, who was closest to the Dementors, shivered from the cold, but her strong will prevented her from surrendering like Harry/Ron. Instead, she raised her wand, frozen, and chanted, "Avada Kedavra... Kill me..."

The green death light flickered in the carriage, illuminating Harry and Ron's terrified, stunned, and bewildered faces.

The light illuminated the face of Teacher Teach Carl, who felt approving and pleased with Hermione's actions at that moment.

It also illuminated the face of Remus John Lupin, the man sleeping in his overcoat.

Unlike Teach's relief, Lupin, standing in the green glow, was shocked by Hermione's appearance as a third-year wizard: "[Avada Kedavra... How can a third-year student know this death curse?]"

What is Dumbledore doing?

Has Hogwarts changed its teaching methods? Have they started teaching the Unforgivable Curse to immature young wizards?

Seeing the palpable killing intent on Hermione's face and the increasingly bright green light emanating from her wand, Lupin quickly stepped forward and stretched out his hand: "No, we can't let this young wizard continue casting death curses; it will affect her future character."

[Dark magic must not be started, for once it is started, the wizard will gradually become addicted and fall into depravity.]

Just as Lupin was about to stop Hermione, Teach stopped him, saying, "My disciple is different from others; you don't need to worry about her."
