Expecto Patronum

As a bizarre Magic Creature, the Silent Mouth has an almost absolute advantage against wizards. It is immune to most spells, and even in his Dark Sleeper state, it would take Sean quite a while to "burst" it.

This Silent Mouth in front of them was different from any they had encountered before.

However, it still possesses a physical form and the ability to be "harmed".

Naja the Occamy and the Selma Lake Monster were entangled together, the two serpentine Magical Creatures like living, thick chains that firmly locked the Silent Mouth, while Sean continuously emitted deadly green light to stop any counterattack from the Silent Mouth.

The Basilisk, which had been waiting for its chance, finally got its best opportunity.

The terrifyingly large body sprang up, and its deadly fangs pierced the center of the Silent Mouth without hesitation!

The snake's head, larger than the cab of a heavy truck, possesses unimaginable biting force, especially after being enhanced by the Magical Creature Cultivation Liquid, making the Basilisk even more terrifying.

Even more terrifying than the bite force was the Basilisk's deadly venom, for which there was almost no antidote!

The Silent Mouth began to tremble violently almost the instant it was bitten. Its pitch-black, semi-transparent mouth gushed out like ashes swept by a hurricane, and the black vortex inside completely stopped spinning and expanded outward.

"Gah—" The piercing and painful scream almost formed a tangible sound wave, and the pebbles on the covered bridge below were shaken and fell off the cliff.

Even Sean frowned and Muffliato.

However, his wand did not stop waving, and one Killing Curse after another was fired at the Silent Mouth.

This special Silent Mouth didn't even get a chance to function; it was completely suppressed and crushed by the one person and three snakes.

Strangulation, biting, venomous fangs, Killing Curse...

The screams of the Silent Mouth finally subsided, and its dark, magical body began to become ethereal and distorted. Then, Naja, the Selma Lake Monster, and the Basilisk all lost their footing.

Three enormous serpentine monsters fell onto the covered bridge, and the middle section broke off completely.

The Silent Mouth transformed into thick black mist that gradually dissipated, like a balloon filled with black fog being punctured and burst by a sharp spike.

The dissipating black mist gradually faded as it floated upwards, and then disappeared into the air.

In the eyes of Sean, Dark Sleeper, a large aggregate of dark power had lost its restraints, and the power returned to its true nature, merging into the world.

The negative emotions that originated from the Silent Mouth also dissipated, but not completely; instead, they became entangled in the magic and entered the world itself.

Perhaps, in the next second, some Dark Wizard in the world who is using Dark Arts will be able to borrow this power.

Sean remained silent, carefully surveying his surroundings. The Obscurus on his body was a small fragment that had escaped the massacre. The lifespan of this Magic Creature might far exceed his imagination.

However, after a thorough inspection, the Silent Mouth had vanished without a trace; it had completely disappeared from this world.

Sean slowly descended, the black mist reforming into a body. He landed on Naja's head, and three enormous serpentine monsters coiled around the bridge and swam to the other side.

"Thump." Sean jumped down and landed steadily, looking at what was in front of him.

Dawson's Patronus Charm didn't last long. Perhaps it was because he was seriously injured, or perhaps he wasn't happy or hopeful enough. Of course, it could also be because the Dementor under Sean's control were too insane.

At this moment, Dawson was being passed around like a broken puppet by a dozen Dementor.

Yes, to pass it on.

Each Dementor removed its hood, revealing a gaping hole in its mouth, which was passionately "kissing" the party organizer.

Sean had no idea how many Dementor had kissed Dawson so many times.

Dementor's Kiss will directly absorb a person's soul, turning them into a mere walking corpse, but it generally won't kill the person; in a physical sense, that person will at least still be alive.

Dawson may be the first person to be "kissed" to death by Dementor.

His pupils were now completely dilated, his skin had turned a horrifying pale blue, his limbs hung limply, and the huge wound in his abdomen had been frozen.

Dawson had lost his last bit of consciousness; he couldn't even retain expressions of fear, despair, or anger on his face. All he left the world was a lifeless body.

His soul had already been completely devoured by more than a dozen Dementor.

Sean watched all of this calmly, without a ripple of emotion rising within him.

He walked slowly over, and the Dementor floated back with their heads down, making way for their master. Dawson's body was carelessly discarded on the stone slab, and no one gave it another glance.

Sean walked over and squatted down, a hint of doubt finally appearing in his eyes.

That was the Black Rhombus Crystal that Dawson used, which had now fallen into the pile of stones.

When Sean activated the Dark Sleeper, even the Silent Mouth dared not attack him again. At that time Dawson inserted the black crystal into his abdomen, the very place where the Silent Mouth had parasitized his body.

Then, the Silent Mouth broke free from the control and oppression of the Dark Sleeper.

This thing was completely unfathomable to Sean. It was wrapped in strange dark magic, and it wasn't a thick mass, but rather a very faint wrapping around the surface of the crystal.

The crystal was an odd, jet-black color, and it didn't get dusty or break after falling into the pile of stones.

"It's like some kind of strange magical combination that has materialized into a specific form..." Sean thought to himself.

This thing, perhaps, can be kept...

Sean felt that if he could figure this out, he might gain a better understanding of the Returners.

Of course, it must be stored properly.

Thinking of this, Sean took out a large number of storage containers and put the black silk crystals into them layer by layer to preserve them, and added a lot of magic spells.

Only then did he exit the state of the Dark Sleeper.

"Phew..." A trace of normal human fatigue and lingering fear finally appeared on Sean's cold and ruthless face.

It wasn't the fear of Dawson and his Silent Mouth was the fear, but the fear of the side effects of the Dark Sleeper.

Just now, he had been resisting the temptation of the dark forces.

Kill Dementor, absorb Dementor... tame the Silent Mouth, absorb the Silent Mouth... and even absorb that black crystal.

Various desires, mixed with strong negative emotions, kept assaulting Sean's mind. As soon as he relaxed his guard even slightly, desires would take advantage of the situation.

Sean may possess terrifying dark power, and may become the true master of darkness, but when that happens, Sean will no longer be Sean.

He understood this very well, so he always held fast to his principles and refused to let himself be completely tempted and corrupted by the forces of darkness.

"Glug glug—ha..." Sean took a swig to Mind Purifier, and the various agitations and evil thoughts in his heart finally subsided.

Meanwhile, in the outside world...

"Minerva, you take a quarter of the people and do nothing else but send magic directly into the magic channel I've constructed."

"Filius, you and Minerva are doing the same thing."

"Professor Snape, you also take a quarter of the people and simultaneously cast offensive spells at the Runes structure I've created. Explosion Charm will suffice. Be careful not to use too much magic, and make sure the spells are cast in sync."

"The rest of you follow me. You are all students who have taken my classes. When the time comes, follow my instructions to light up the Runes symbols."

Professor Babbling was already outside the barrier, inscribing runes with Runes to create a sizable Ancient Runes magic passage, and was giving instructions to everyone.

The plaza outside the barrier was already packed with people. Apart from a few professors and first- and second-year students who stayed behind at the school, all the other professors and the vast majority of students had gathered in the plaza.

Charlotte had summoned them, but they didn't know the specifics. They only saw the Defense Against the Dark Arts assistant rush into the Great Hall and loudly order all students with some magical abilities to leave.

As a result, most of the students in the third grade and above came.

Everyone was already huddled in their sleeping bags, talking furtively.

Then, as word spread, everyone learned that the new teaching assistant, Max Dawson, was actually the culprit behind tonight's incident. Sean, in the process of arresting him, was drawn into this unknown realm.

In other words, fourth-year student Sean is facing a powerful wizard who graduated many years ago, and this wizard even possesses methods and magic that the professors have never known.

Many girls immediately covered their mouths, as if Sean would die a second sooner if they said even one more word.

Meanwhile, Sean's friends, such as the Harry trio, the Weasley twins, Cedric, and others, were already anxiously asking the professor for a solution.

Even Malfoy brought a group of Slytherin students to the scene. His face was gloomy, but when he asked Snape how he could help, his tone was very urgent.

The students' chatter subsided a little after Professor McGonagall repeated it three times.

Hermione, Daisy, and Stephanie had already blended into the crowd.

The girl with long silver hair calmly looked at Daisy, whose face was full of anxiety, and said softly, "You heard what Professor Babbling said. She is an expert in Ancient Runes. Our impulsiveness is meaningless."

"But, but..." Daisy looked up, "Sean has been trapped inside for so long!"

Stephanie fell silent as she looked at the tears welling up in the girl's eyes.

At this moment, Hermione said softly, "Don't be impulsive, Daisy. Miss Ollivander is right. We must listen to Professor Babbling so that we can rescue Sean more quickly."

"Hermione ..." Daisy turned to look at her, the worry and fear in her eyes making Hermione's heart clench. "I'm so scared... What if something happens to Sean ... He can Trace Flash, but he didn't escape..."

The girl's voice was thick with sobs, making her sound pitiful.

"No, no," Hermione forced a smile. "He has so many tricks up his sleeve, and don't forget, he has Dave and the others..."

The two clasped hands.

Only now did they realize that Sean had faced danger before, but back then, they either hadn't witnessed it firsthand, or Sean had someone like Grindelwald or Dumbledore by his side. But now, Sean was right in front of them, trapped in a complete predicament—no, according to Charlotte and Colton, it was a trap set for Sean.

The boy who always managed to find a solution didn't appear before them with a smile anytime soon; the professors were all busy with anxious and worried expressions.

Sean, please don't let anything happen... I beg you...

Hermione silently closed her eyes.

Stephanie watched this scene from the side, gently rubbing her arms, her deep black eyes revealing a deep thought.

"Everyone," Professor McGonagall's stern voice rang out, "Follow your assigned groups and keep up with the professors! And absolutely, absolutely follow the professors' instructions!"

"Understood!" the students responded loudly.

Everyone quickly took their positions and raised their wands in unison.

"Bathsheba, let's begin." Professor McGonagall took a deep breath and turned to Professor Babbling.

Professor Babbling stood in the center, slowly drawing a huge Runes, making various gestures with her wand, and then called out to Professor McGonagall and Professor Flitwick, "Begin."

"Everyone, unleash your magic!" Professor McGonagall took the lead, pointing her wand at the magic channel in front of her.

The simultaneous output of magic from hundreds of people created a spectacular and dazzling sight. Hundreds of magical chains connected the magic channels and the wizards holding wands, illuminating the square as if it were daytime.

Professor Babbling continued to construct Ancient Runes, and then quickly gave orders. Behind her, her excellent Ancient Runes students, led by Selma Murphy, also began to rapidly construct runes.

The spherical barrier was like a water-filled balloon that had been gently tapped, causing its surface to ripple.

The fluctuations did not subside; as Professor Babbling continued his actions, the fluctuations became increasingly intense, and the barrier even grew larger.

Daisy stood at the very front of the crowd, frantically channeling her magic as if she were about to exhaust herself, her eyes fixed on the entrance to the covered bridge.

I want to see you the moment I open my eyes...

Inside the barrier, Sean, Dark Sleeper, looked up in surprise as the barrier suddenly began to fluctuate...

"Quickly, Naja, you guys, come in quickly..."

Outside the barrier, Babbling shouted, "Snape!"

Snape raised his wand. "Everyone, three, two... one!"

"Confringo!"

Countless red Explosion Charm bombarded the area, causing the barrier to tremble violently.

Then—"Boo!"

The dull sound was like a heavy blow to everyone's eardrums.

However, Professor Babbling's method is correct!

The spherical barrier is rapidly dissipating!

"Sean!"

"Miss Potter! Watch out!" Professor McGonagall immediately gave chase.

The other students put away their wands, and the huge light quickly faded. They rubbed their eyes and looked into the barrier.

"That is..."

"It's Dementor!"

"The Dementor are surrounding Sean!"

Professor McGonagall's eyes widened suddenly. She saw a body lying on the ground, and she also saw Sean surrounded by more than a dozen terrifying Dementor!

And all those Dementor had taken off their hoods!

Professor McGonagall felt a chill run down her spine and immediately raised her wand: "Call of God—"

Someone was faster than her!

Daisy's shrill, tearful voice rang out. "Don't touch him! Expecto Patronum!"

A silver-white Fire Dragon, tens of meters long, emerged from the magic wand, illuminating the entire night sky!
