It doesn't look or smell like a real potion.

"Like some potion that makes wild animals excited," Tonks muttered. "What do they want to do?"

Lupin shook his head: "Go back first and inform Harry."

Tonks nodded obediently. She was not the type of person who had big breasts and no brains. She was not one of these two words. Although she wanted to be the first type of person, and although Metamorphmagus could transform her, it was magic after all, and she could not get over it in her heart.

She crouched down and slipped away through the gap in the crowd.

In less than ten minutes, she came back.

"Tonks?" Lupin lowered his voice. "What's going on?"

"Shadow locked." Tonks shook her head.

Lupin frowned, raised his head, and looked at two scales counterclockwise along the head in front of him.

Tonks grabbed his hand and said, "Stop looking. The caster isn't here."

"I just tried it. The caster was very skilled and I couldn't crack it. It must have existed for a long time, at least half a year..."

Lupin's frown deepened.

"It's not like I haven't thought about leaving," Tonks went on, "but it's obviously not the time for me to leave now."

"Why?" Lupin asked her.

Tonks said confidently: "I am an Auror, and you are an ordinary citizen. Although we are both comrades in the Order of the Phoenix, shouldn't it be natural for Aurors to protect ordinary citizens?"

"I wish all Aurors were like you." Lupin said with a smile, "But Tonks, it's dangerous to stay here."

Tonks said nothing, but raised her wand.

Cast the Disillusionment Spell.

Her body disappeared bit by bit as if being erased by an eraser.

"I can do this," Tonks said softly, "Is it okay if they can't see me?"

Lupin tilted his head to the side with a strange expression: "Tonks, don't talk into my ear."

"I'm just making less noise," Tonks replied softly. The Disillusionment Charm made it impossible to see her movements clearly. All she could see was Lupin's head folded almost 90 degrees.

Just at this moment.

The moon rose. The weather was very good tonight, clear and cloudless. It climbed naked into the night sky.

At the moment when the moonlight falls.

The bodies of the werewolves around began to change.

The torso, limbs, and head began to twist and change hideously, and in the blink of an eye they turned into a werewolf.

Lupin did not change. He drank the potion made by Harry and Snape, and the transformation time was delayed by more than an hour.

Animality corrodes humanity.

The bottle of potion on the table was not a potion to cure lycanthropy as they had expected. In the moonlight, its flame looked even more eerie and it emitted a strange aroma.

After the transformation, the potion took effect and they were affected.

With red eyes, he sniffed the scent and ran towards Tonks, who had not yet transformed and was invisible with the Disillusionment Charm.

Lupin was quick with his hands and eyes, waving his wand and casting a spell to isolate the breath.

Tonks cast a Disillusionment Charm on him.

The wolves pounced in vain and looked blankly in front of them - in their vision, this place was completely empty, and they even subconsciously wanted to stay away from it, feeling disgusted with this small open space.

They stay away.

He stared at the werewolf closest to him with hatred and let out a shrill howl. Then, without hesitation, he pounced on it, waving his claws and biting it.

"Werewolf, I mean, are all werewolves like this after they transform except you?" Tonks looked at them, her face turning pale.

Lupin shook his head: "No."

"Although werewolves lose their brains after transforming, they are still not indistinguishable from their own kind."

Lupin had no experience of transforming with other werewolves, but he had heard that when werewolves gathered together to transform, they would not attack each other - wolves are social animals, and so are werewolves.

"Is that the effect of the potion?" Tonks raised her wand.

With a whoosh sound——

A stone flew out quickly and smashed the bottle with a clang, splashing glass and half-full wine all over the floor, with the flames still burning.

Even without the bottle fixed in place, the scent emanated even more violently.

Clear water like a spring!

Tonks waved her wand again.

The water gushed out, passing through the fighting and killing wolves, and fell onto the potion. With a hissing sound, a milky white mist surged up, and the flame went out. Except for the color, it seemed to be no different from an ordinary flame.

only……

The flames died down, but the potion was still taking effect.

The werewolves fought each other with brutality and viciousness, without any change.

"So the Death Eaters' plot is to make these werewolves kill each other?" Tonks tilted her head. The sound of the werewolves fighting was terrible, but she was not so scared next to Lupin. "Why do they have to let Harry and the others know?"

"Harry guessed that it was a bargaining chip to lure him and Dumbledore away from Hogwarts," Lupin replied softly.

Tonks smiled softly and was about to say something else.

"Oh, no..."

"Help!"

A shrill and helpless wailing sounded.

Several barrier spells flashed.

Lupin and Tonks were both stunned. They turned their heads, trying to catch each other's gaze, but under the Disillusionment Curse, they could not see each other.

"There are others besides us." Tonks said anxiously, "We have to go and take a look."

Lupin responded: "Of course."

He paused for a moment. "Grab my sleeve."

Tonks reached out her hand, groped around openly, and then took his hand.

"I meant the sleeves." Lupin was startled and emphasized it again.

Tonks reluctantly moved her hand down and grasped the small corner of the sleeve.

The two of them hurried over.

The one who called for help was a middle-aged man in his forties. He waved his wand and used barrier spells and transfiguration spells alternately to hinder the werewolves that pounced on him. He was lucky, perhaps because when he first sneaked in, he hid in a corner and was not very conspicuous, so there were only two werewolves that pounced on him.

He can still barely stop it now.

Can……

It was visibly that his spell was becoming increasingly weaker.

Maybe next time, the werewolf's claws would pierce his skin.

"There are so many obstacles!" Tonks swung her wand without hesitation.

The spell shot out and hit the werewolf. Her spell was more powerful than the one used by the man. The huge impact force made the werewolf stumble back several steps.

Lupin waved his wand without making a sound.

Casting spells silently while in the Disillusionment Charm was not very useful in a duel between top wizards - everyone could capture magic power or counter the Disillusionment Charm, but this skill was extremely useful against these werewolves who had no intelligence, or even had an additional layer of dementia.

The werewolves didn't even react, how could the air release magic like a wizard.

The two werewolves that harassed the middle-aged man were immediately tied up with iron chains, hung high up, and thrown into the werewolf pile.

Lupin also cast several cutting spells at one of the werewolves, barely able to tear a small wound on the werewolf's skin.

The smell of blood further stimulated the manic werewolves.
