Hogwarts starts with stealing power.

Lin Xia did not intend to take a roundabout approach like them and solve the problems one by one.

Since there are Death Eaters hiding in the ranks of the guardian rune formation, the easiest way to identify them is to cast a Patronus Charm on them.

Ordinary wizards will not suffer any harm as long as they are not facing an offensive Patronus Charm.

But Death Eaters are different.

No matter whether it is an offensive or defensive Patronus spell, to them it is like being burned by fire or boiling water, and the reaction is extremely strong.

If their peers around them noticed their reactions, they would know that there was definitely something wrong with them.

It's not necessarily that Draco and Hermione couldn't think of this solution, it's just that their thinking was limited.

Their Patronus Charm cannot produce such great power, so even if they know this method, they may not be able to implement it well.

But Lin Xia is different.

As long as she wanted, her Patronus Charm could circle around the guardian rune formation.

But she didn't want to show her patronus as being too powerful. Apart from herself, no one else knew that her patronus could transform, so Lin Xia only planned to use the most basic ball of white light for patrolling.

Lin Xia quickly told the two of them her thoughts and ignored them, instead walking quickly to a crowded place.

Gathered here are free wizards, each of whom forms a large team and spontaneously launches attack spells into the sky.

There is a person in the team who possesses a strange item that can concentrate the scattered energy and shoot it towards one place.

This rare object often appears in large-scale wars, and no one knows how that person got it.

Even the Ministry of Magic is very rare to have such a rare item, which can have a great impact on the war situation and even rewrite the war situation.

"Lin Xia, you're back. Where did you go just now? We couldn't find you."

"Lin Xia, you are still too young. You shouldn't step into the battlefield. Just listen to us and leave Hogsmeade Station immediately!"

As soon as the wizards saw Lin Xia, they all greeted her and persuaded her to leave quickly.

Many people had heard of Lin Xia's "great achievements" before they saw her.

Anyone who dares to act alone on the streets and lure Death Eaters into captivity must be no unknown person.

They have long known that although Lin Xia, the underage wizard, looks gentle, he actually has a strong magical talent and is as capable as an Auror.

With Lin Xia's joining, they all felt that the power of the attack spells they launched became much stronger.

But Lin Xia is still too young after all!
Such a good seedling should not be wasted at the station.

When Lin Xia was attacking in the queue, they wanted Lin Xia to leave, but they couldn't persuade her.

Later they saw the professor from Hogwarts appear and planned to ask them to take Lin Xia away, but unexpectedly Lin Xia disappeared in the blink of an eye.

How could they not understand at this time that Lin Xia didn't want to leave at all.

Lin Xia pretended not to hear their persuasion, but found the leader, who was also the wizard who provided the strange objects.

She did not hide it from others and said quickly, "I received news that there are Death Eaters who disguised themselves as Aurors through Polyjuice Potion and mixed in with the defense rune formation. I need to find them out."

The leading wizard's expression instantly became solemn. "Is your source of information reliable? You can't say such things casually. They are Aurors from the Ministry of Magic. If you suspect the wrong one, it may disrupt the deployment of the Ministry of Magic."

Lin Xia: "It's reliable, and I have a very simple way to identify Death Eaters."

The man asked curiously, "What method?"

Lin Xia: "Death Eaters are afraid of the Patronus Charm. I need a wizard who can use the Patronus Charm."

If she were to cast the Patronus Charm by herself, it would reveal her strength too much.

But if many wizards act together, it won't seem out of place.

Lin Xia's request made others feel troubled.

These wizards are all old. Even if they used to be Aurors, that was the glory of their youth when their physical strength was at its peak.

If it weren't for their declining physical strength, they would not have been able to retreat from the Aurors.

The Patronus Charm is not something that ordinary wizards can learn. If they knew the Patronus Charm, the Ministry of Magic would not let them go so easily.

But the leading wizard just thought for a while and said, "Give me ten minutes and I'll find it for you."

He did not make any other movements, but just raised his wand and sent a patronus spell towards the sky: "Expecto Patronus!"

An eagle with a silver-white glow appeared in front of everyone. The eagle flew majestically among the crowd, and its sharp eyes scanned the crowd, as if looking for something.

After a while, a wizard also cast the Patronus Charm in response.

Some wizards cannot summon a patronus, but they can move the white ball of light flexibly, and the effect produced is no weaker than that of a patronus.

Some wizards were able to summon patronuses, and they summoned them out one after another to join the majestic eagle.

The other ordinary wizards were all shocked when they saw this.

They didn't expect that there were so many people here who knew the guardian spell.

Lin Xia was not very surprised.

She knew that the Ministry of Magic specially selected people to come to Hogsmeade, and those who were selected by the Ministry of Magic all had extraordinary abilities.

After a while, ten people came over, all of whom had the Patronus Charm.

The leading wizard summoned the eagle not to show off, but to convey a message to other patronuses, indicating that he needed help.

The other guardians found out and passed the news to their master, so the group of people came over.

Everyone gathered, and Lin Xia said quickly without waiting for them to ask: "We need to use the Patronus Charm to check the Aurors. There are Death Eaters who have infiltrated the Aurors!"

The wizards were in a state of confusion. An old wizard even said sternly, "Young wizard, you can't lie about this kind of thing. Where did you get the news from?!"

Lin Xia glanced at him. This wizard was not dressed ordinary, his hair and beard were carefully groomed, and he looked a bit like an aristocrat in the magic world.

"It doesn't matter where I got the news from. What's important is that I can confirm that the news is true. And as long as we don't have malicious intentions, the Patronus Charm we cast will not have any effect on the Aurors."

The wizard with the Eagle Patronus spoke up: "I called you here because I want your help. Let's use our Patronus to check if there are any Death Eaters among the Aurors in the rune formation?"

"But..." A wizard said hesitantly, "Will the Ministry of Magic agree to us doing this?"

Someone suddenly sneered: "You have to agree even if you don't agree. If you don't agree, is there something fishy going on?
If the elite Aurors had infiltrated the Death Eaters, the Ministry of Magic would be ridiculed and lose face if this got out!
It's better to believe it than not to believe it. It won't take much effort to check it out. We all have the Patronus Charm, so there's no need for the Ministry of Magic to send someone to check it out."

Lin Xia: "I think so too, and what we are doing is also helping the Ministry of Magic to eliminate a danger in advance."

"You don't need the Ministry of Magic's consent. I am an official in the Ministry of Magic. I will take you for examination." A serious voice sounded, and it was the wizard who had just questioned Lin Xia.

When Lin Xia saw him, she felt that he behaved like an aristocrat. She never thought that he actually worked in the Ministry of Magic.

On the other side, Draco and Hermione did not give up either.

The guardian rune array was divided into more than a dozen rows, with Death Eaters hiding in each row.

Some queues are difficult to dig out, but some are very easy. They specifically look for those that are easier to knock out.

At the same time, three Hogwarts professors had arrived at the outer edge.

The three professors all Apparated to different directions—south, west, and north.

The reason they didn't go to the east was that they found that the east seemed to have been cleaned up.

There are residual flame fluctuations in the east, which must be where a battle between wizards took place.

Moreover, there are the fewest werewolves who respond by howling in the east, so this is nothing to be afraid of.

Three wizards appeared in three different directions at the same time, waving their wands with grim expressions and using the "Burning Flame" together.

Pfft!

Lines of fire were ignited in the forest, and the sparks of fire fell into the eyes of everyone in the station. Some wizards couldn't help but frown.

"Setting the mountain on fire, is this to stop the werewolves from attacking?"

"Today is a full moon night. There are too many werewolves gathered outside the mountains. This is the only way to scare them away."

"I'm afraid that this fire will not burn outward, but inward. If we can't put it out, we will all be doomed."

Three professors here.

After they set the fire, they gathered together through Apparition and discussed the fire situation.

Snape said coldly: "We have opened up a fire isolation zone, and the fire cannot burn in. We must return to the station quickly to avoid any accidents!"

Flitwick shook his head: "Snape, don't be so anxious, we still have to observe the situation."

Mag thought the same thing.

"Let's stay here and observe for a while to see if these flames can drive back the wolves outside. If they still can't drive them back, we have to think of other ways."

As the forest caught fire, the howling of wolves in the mountains became noticeably weaker.

Many werewolves lost their minds and subconsciously retreated when they saw the raging fire.

Others would rather run farther away than run to where there is fire.

Wild animals also have the instinct to seek benefits and avoid harm. Is there something in the flames that attracts them? Why would they rush into the fire?

In a villa, Bellatrix stared at Fenrir grimly.

"I asked you to summon an army of werewolves to crush those mediocre wizards, and this is how you responded to my plan. Where is your so-called army of werewolves?"

Her eyes were cold and fierce, with a strangely deep black hue. The black veins on her arms were faintly visible and kept twisting, as if they would burst out of her body in the next second.

Fenrir is huge in size and has strong muscles. In werewolf form, his fur is darker red than other werewolves, and his saliva is highly infectious with wolf poison.

He is more of a beast than other werewolves, but a rational beast. The full moon night enhances his original brutality and also strengthens his savage instincts.

Facing the furious Bellatrix, he did not confront her head-on, but explained expressionlessly:
"All the werewolves I brought with me died. They fell into the trap set by the Aurors of the Ministry of Magic. This is the only way to summon the werewolves."

Although he was explaining, his eyes were flashing a dark red light, which made the other Death Eaters very alert, fearing that Fenrir would go berserk the next moment.

Except for Bellatrix who was not afraid of Fenrir at all, the other Death Eaters might not be able to avoid Fenrir's angry attack.

Fenrir's words were obviously perfunctory, but they fooled Bella, and Bella hated the Aurors in the Ministry of Magic even more.

"Aurors, those despicable hyenas, and the sinister Dumbledore!"

Black veins meandered up along the arms, soon reaching the neck, and quickly covering the entire face.

Seeing Bella in this form, even Fenrir couldn't help but take a few steps back. He felt a strong and dangerous aura from her.

But soon, Bella took a deep breath, calmed down, and asked Fenrir.

"Can the werewolves be summoned?"

Fenrir opened his wolf mouth, saliva dripped out, and there was some meat residue between his teeth.

"Those werewolves are not my subordinates. They may not come here. If you need me, I will subdue them now."

Bella said angrily, "It will be too late by the time you go to conquer it!"

She walked around, her eyes red. "Although there are no werewolves charging, we can release something else."

Bella suddenly turned her head and stared at the Death Eaters present, her eyes seemed to be choosing which one would be a good sacrifice.
-
Mag and others floated above the forest and watched the fire.

They set up a firebreak in advance, and the fire did not burn inwards, but burned outwards, constantly forcing back the approaching werewolves.

Mag pondered for a moment and said, "The flames we set are just ordinary flames. If the werewolves really want to break through, they can be solved quickly. We have to set up another defensive magic rune array to confuse the werewolves."

Today is the werewolf's home court. Relying on their powerful recovery ability, they cannot be killed by attacking magic arrays, and even if they are used, they will not achieve good results.

But if you use a defensive magic array, the mad werewolf will keep circling around and won't be able to break through the defense line.

The other two professors thought this method was good and started to arrange it immediately.

Because they were professors at Hogwarts, they carried a lot of school materials with them. The three of them pieced together and quickly put together a simple version of the defensive magic rune array.

——Intended to confuse, unable to attack.

If a rational wizard were to use this magic array, he would not be able to deceive them. However, this may not be the case if it were a werewolf.

While they were making the arrangements, Lin Xia had already begun searching for the Death Eaters who had infiltrated the ranks.

The wizard who claimed to be an official from the Ministry of Magic led them directly to the queue without saying hello to anyone else.

The Auror who was guarding an important node of the magic rune array frowned when he saw the wizard, and sent someone to communicate with him immediately.

"What are you doing here? We are fighting the Death Eaters. The situation is critical. If you have nothing to do, leave!"

Lin Xia and others followed behind and looked at each other in surprise when they heard the words.

The person who brought them here seems to have a bad relationship with the Aurors of the Ministry of Magic. (End of this chapter)
