The Philosopher's Stone has been obtained, and now it's time to verify whether his conjecture will take effect. And this kind of extremely dangerous thing, he will not do.

The Philosopher's Stone has no effect on the black clouds, but Arthur can borrow the power of the audience to destroy it.

However, if the Philosopher's Stone explodes with energy at the moment it touches the black cloud, or if it produces a magical black hole, then the person who throws the Philosopher's Stone into the black cloud will definitely die instantly.

Therefore, it is more appropriate to leave this extremely threatening thing to Grindelwald's most trusted saints.

"Ahhhh I want to kill you right now!"

Looking at Arthur's back, Lilith cried out through gritted teeth. At this point, she no longer had the charming posture she had in front of Harry and Ron.

She knew very well in her heart that Arthur was so confident that he had captured her life.

Now that the entire Hogwarts Castle has been reduced to a battlefield, the appearance of the Boulder Soldiers has relieved the professors, but the disadvantages are still there. Exhausted by repelling the Death Eaters who had entered the castle, they roamed the castle all the way around, and it was difficult to find them for a while.

Time is of the essence of victory, and neither Arthur nor Lilith can afford to waste time going to the other professors and throwing the Philosopher's Stone into the clouds.

And between the two of them, the relationship is very delicate.

As a saint, Lilith's first goal is to keep Arthur safe. Therefore, it must not be possible for Arthur to go on an adventure.

She was left alone with the Philosopher's Stone to approach the black clouds.

But...

The idea that the Philosopher's Stone could hack the black cloud and make it disappear from the top of Hogwarts Castle was Arthur's reasoning.

There is simply no evidence to support this reasoning.

So... What if the Philosopher's Stone has no effect on the black clouds?

'Or... Now knock him out and bring him back to Durmstrang Academy? ，

In the dim and cold corridor, Arthur held his wand and lit the road ahead with fluorescent flashes. Lilith, who was walking behind Arthur, looked at Arthur's back, and the wand in her hand gradually rose.

After evaluating the pros and cons, the idea of taking Arthur away immediately occupied Lilith's entire thought.

Rather than risk breaking the dark clouds, taking Arthur with him is the safest thing.

"If I die, will you be sad and shed tears for me?"

Eventually, Lilith gave up on the idea in her head and put her wand down.

Because Master Grindelwald had told her that Arthur would leave Hogwarts School of Witchcraft and Wizardry on his own initiative, instead of forcing him to come to Durmstrang House.

"I will put you in the first place, and let everyone sing the praises of your bravery."

Arthur looked back, glanced at Lilith suspiciously, then turned his head back to look at the stone arch where he was going, and said suddenly.

A Grindelwald saint selflessly sacrificed his god to force out the evil Death Eaters in order to save Hogwarts from being invaded by Death Eaters and protect the students.

What a touching story. If it is written, it will definitely explode.

"You're trying to make money with my story, right?"

Lilith saw Arthur's thoughts at a glance, snorted coldly, and quickly caught up with Arthur.

"How is that possible? Am I that kind of person?"

"You are! Your obsession with money is greater than Voldemort's ambition to rule the wizarding world!" ….

"That's what you mean, isn't it?"

Arthur spread his hands and walked on without explanation.

Half an hour had passed since they walked into a checkpoint, and neither of them knew what was going on outside. It's possible that Headmaster Dumbledore has found a way to break the dark clouds and drive the Death Eaters out of Hogwarts. It is also possible that Hogwarts Castle has been lost, and the professors have to retreat to the Great Hall.

In such an emergency, Arthur was in no mood to waste time with Lilith here......

At the same time, a new situation appeared at the gates of Hogwarts Castle. The black rain from the black clouds above the castle has already made Huo

Gwarts Castle became an island in the middle of a black ocean.

Under the continuous rain of black clouds, the height of the black ocean had already exceeded the last step of the castle gate, and in the messy pace of the house-elves controlled by the black mud monster, and the roar of beasts, it spread towards the castle.

And the magical creations that stood in their way were all neutralized by their assimilation. Even the ancient spells on the castle walls were absorbed by them and lost their function.

They've evolved again!

Rumble! Rumble! Rumble!

The Boulder Soldier is down!

They were destroyed by the black ocean of black mud monsters, causing them to become immobile stones.

Professor McGonagall, who was standing behind the normal house-elf, changed her face when she saw this. He immediately shouted at Hagrid, who was guarding the entrance to the auditorium not far away.

"Hagrid! Take the students to the principal's office! We can't stay here any longer!"

"Yes! Professor McGonagall!"

Hagrid, who was more than two meters tall, stood at the entrance of the auditorium like a door god. His eyes are sharp and vigilant, observing any wind and grass around him. Hearing the order, he quickly turned around and yelled at the trembling students in the auditorium.

"Stand up! Follow me!"

I watched as the young wizards followed Hagrid's huge figure in the direction of the magic staircase. Professor McGonagall frowned, then spoke to the house-elf Lodge beside her.

"Rocky, you take your compatriots to protect the children."

"Yes! Professor McGonagall!"

After receiving the order, Rocky beckoned a dozen house-elves beside him to disappear from the spot using apparition shifting. They're going to the front of Hagrid's group and help them create a safe passage.

"The walls are flying!"

Professor McGonagall raised her wand, the tip of which pointed to the stone-stacked wall behind it, and swung it vigorously towards the castle entrance.

Katsa!

Rumble!

A large, thick wall slammed into the door, pushing out all the black mud monsters that stood in its way and the black water that came in.

Since the opponent is already immune to magic, it can only be fought against by physical means.

After eliminating the black water remaining in the hall of the entrance with "Filth Retreat", Professor McGonagall said to the family beside her.

"Go and block all the windows of all the classrooms on the first floor with boulders! You all know where the castle storage room is, right?"

These evil black mud monsters have evolved to the realm of magic that can destroy buildings. If they were to enter Hogwarts Castle and destroy the spell that had stabilized the foundation, the thousand-year-old castle would collapse. ….

"Yes! Professor McGonagall!"

With that, the house-elves vanished from Professor McGonagall one by one.

As Hogwarts supporters, they certainly know where to get to the slate early.

When all the house-elves around her were gone, Professor McGonagall looked gloomily at the stone wall that had been violently slammed into by the black mud monster.

These black mud monsters, although they have terrifying magic immunity, do not have a high IQ. For so long there has been no option to invade the interior from the windows on the first floor of the entire castle.

But as the black ocean outside the house gets higher and higher, they will definitely find the window under the guidance of the black water.

For now, the task of blocking the windows to prevent black water from wading through the windows into the castle is left to the house-elves. Professor McGonagall, she had to make sure that the wall in front of her wouldn't be knocked open by the black mud monsters.

This difficult task can only be her, and she is the only one.

In addition to herself, Professor Dumbledore was besieged by the Death Eaters outside the castle, while Professor Sprout and Professor Feliwick were searching for the missing students inside the castle.

Hagrid found that there weren't enough students in the auditorium, five fewer than on the Christmas registration list.

Arthur Pendragon of Slytherin House is with Lilith, a professor at Defense Against the Dark Arts. But the three Wesley brothers of Gryffindor House, and Harry Boe

Tin's whereabouts are unknown.

Fearing that the four of them would be found and killed by the Death Eaters in the castle, Professor Sprout and Professor Felivier immediately decided that they would search for the four Gryffindor students.

Let Professor McGonagall lead the house-elves against the invasion of the Black Clay Monsters.

And Professor Snape, Professor McGonagall has not seen him since he returned to Hogwarts Castle.

"Hopefully, Headmaster Dumbledore can get rid of that dark cloud soon..."

......

"Hey! Arthur!"

"Hey! Sister Lilith!"

"Why are you here?"

Arthur, who had just taken Lilith to the corridor on the eighth floor and was about to go to Torifeed, was suddenly frightened by the Wesley twins who had turned out of the oil painting next to him.

Arthur clearly remembered that these two people were in the auditorium, when did they come here?

"Hehe, Arthur, didn't you say there were a lot of treasures hidden there..."

"George and I thought we might be able to get a magic item out of it that would fight those monsters."

"That's why Fred and I came here while Hagrid was fighting the Death Eaters."

George and Fred spoke one by one, without pause between the words, as if they were talking alone.

"Look, what did we find?"

"A golden crown! I'm willing to bet it's definitely Ravenclaw's crown!"

When George finished speaking, Fred quickly pulled out a glittering crown encrusted with gems from behind him. To convince Arthur, they did find the Ravenclaw Tiara.

George also pointed to the bottom of the golden crown - "The wisdom of the people of China is the greatest treasure of mankind".

"We wondered if there was anything we could do to dispel the black cloud, and Ravenclaw's golden crown appeared right in front of us."

Fred explained proudly.

In order to protect the secret of the "Room of Request", he also deliberately replaced it with "that place". ….

"You..."

Arthur saw that the two of them actually took out Voldemort's Horcruxes at this time. He already knew that the Horcrux contained ancient creations, and his face changed in an instant. Just about to let the two of them put it back quickly, in case the black clouds outside Hogwarts Castle sensed the ancient creation in the Horcrux and released the ancient creation.

But at this moment, a group of house-elves suddenly appeared around them. These house-elves looked anxious, completely oblivious to the existence of the four Arthurs.

[I have known an old book friend for ten years to recommend to me to chase books,

At the entrance of the Bing House, Arthur used the magic technique bestowed upon him by the Will of the World against the golden crown of Ravenclaw at the moment when the Sumerian Ancient Coin Barrier was activated.

With her head bowed and her eyes closed, the holy phantage of Sister St. Mary's with folded hands reappeared behind William, and she slowly opened her arms to hold the Ravenclaw crown in George's hand......

'How did he use this spell on a golden crown?!' Could it be !!!,

Lilith, who had been standing behind Arthur, saw the phantom of Sister St. Mary again, her face changed and her heart was shocked.

This spell is a forbidden spell that can kill that terrifying octopus monster, Arthur actually used it on a Ravenclaw crown... Could that be?

Just as Lilith was about to open her mouth to confirm that her guess was correct, the phantom of St. Mary disappeared from her presence. Arthur said to the house-elves after putting the Ravenclaw crown in his purse.

"Come out of one of you, help me get them both to safety."

"Yes, Lord Pendragon! It's a pleasure for me to be here for you."

A house-elf standing furthest away from the Wesley Twins hurriedly beckoned, ran quickly to Arthur, bowed and said.

Ever since Arthur helped their house-elves deal with the monster in their land, "Arthur Pendragon is the savior of house-elves" has been passed on by house-elves to the ears of all house-elves in England.

Therefore, it is the honor of every house-elf to be able to do things for their own savior.

"Let's go! Professor Stienkana. With such a sudden change, Headmaster Dumbledore outside the castle must be under great pressure."

After seeing the house-elf named Linlin take the unconscious Wesley Twins away, Arthur walked briskly in the direction of Toriga, where the corridor was semi-open, and it was also the highest place in Hogwarts Castle except for the tower.

Approaching the black clouds from the torigai's corridor is why Arthur brought Lilith here.

"Could that just be that..."
