A magical journey that begins in Azkaban

Baldwin's laboratory is hidden deep in Fort Detrick, which was built by Muggles. Since the snake-man virus incident, the ground building has become an empty city. The rooms that were once highly protected and strictly confidential are now open to birds and raccoons to build nests.

In the abandoned culture dish, the dried nutrient solution left vague traces of unknown organisms. The broken test tubes, scattered documents, and discarded protective clothing in the corridor... can't help but make people feel terrified.

The surface of the tunnel dug by the goblins in advance is as smooth as a mirror, like a huge slide, which can quickly send people to the outside of the cave. A whistling sound echoed and overlapped along the tunnel, like a magic sound from the abyss, constantly echoing in this secret underground world.

Several goblins wearing leather armor and holding wands patrolled inside and outside the cave. Sometimes they sat on the abandoned wooden boxes in a daze, and sometimes they walked to the corner and whispered about what happened recently among the Death Eaters, without realizing the impending danger.

Roger carefully rotated the lens on the crow mask to further expand the field of view. Soon, the positions of more than 20 enemies were accurately marked, with red dots flashing in his field of vision.

"Hey, there's another one there?" He couldn't help but exclaim in his heart.

A drunken goblin was lying on a pile of debris, hugging a huge bottle of wine and sleeping soundly. If it weren't for the other invisible Aurors around him, he would probably ignore this potential threat.

Just as he was about to pull out a dagger from his boot to assassinate, dozens of spells lit up almost at the same time. The light of the spell drew dazzling tracks in the darkness, illuminating the entire space. The unsuspecting goblins were hit by the spell before they could react.

"Petrified."

The Aurors' actions were fast and precise, as if they had been rehearsed countless times. As soon as they emerged from the invisible state, they immediately used the illusion spell and disappeared into the air again, leaving only a series of blurred afterimages.

The goblins who were hit by the spell were like stone sculptures, stiffly fixed in place. A few slightly alert goblins noticed the spell flashing in their peripheral vision, and just as they were about to open their mouths to warn, they were mercilessly petrified by the second round of attacks.

In just about 10 seconds, all the goblins outside the cave were completely controlled. The whole process was silent, like a breeze blowing, without causing any ripples.

A trace of approval flashed in Rogge's eyes, and he put the dagger back into his boot. He walked past the petrified goblins quickly, his movements so light that even the sound of his footsteps could not be heard. Soon, he entered the laboratory marked "15".

"The virus research laboratory is in No. 9." He muttered to himself, looking around vigilantly.

The interior of the laboratory was gloomy and terrifying, with several sleeping vampires hanging upside down from the ceiling, their fangs flashing coldly in the dim light. Rogge carefully bypassed them and quietly walked to the passage on the right.

At this moment, an accident happened. A bearded wizard suddenly stood up from the second floor. There was still grease from the barbecue at the corner of his mouth, and he was chewing a bone, making an unsettling crunching sound.

Rogge froze instantly, his muscles tensed, ready to deal with possible conflicts at any time. He held his breath and tried to slow down his heartbeat, fearing that the werewolves or vampires with keen senses would notice something unusual.

The wizard glanced around vigilantly, his eyes sharp as a knife. The vampire not far away opened his blood-red eyes and asked curiously: "Youer, what's wrong? Do you want to go back for Christmas?"

"There is a smell." Youer flared his nostrils, trying to distinguish the turbid smell in the air, "A smell of perfume."

"Perfume?" The vampire landed lightly on the ground, and his blood-red eyes scanned every corner of the laboratory like an X-ray.

Rogge's brain was like a high-speed magic machine, quickly recalling Professor Lupin's teachings in the Defense Against the Dark Arts class.

Once a wizard is infected with the werewolf virus, not only will his appearance change, but his senses will also be amazingly enhanced. Even on a non-full moon night, these half-human, half-wolf creatures can sniff out the slightest changes in the air like the most sensitive bloodhounds.

"Vampires are completely different," Roger muttered in his heart, as if he heard Professor Lupin's magnetic voice again, "Their eyes are extremely afraid of light, and they can't see clearly even one meter away in the sun. But don't be fooled by their fragile eyesight, their ears are the most sensitive monitors in the magic world."

Lupin drew a diagram of the structure of a vampire's ear on the blackboard, with a lot of imperceptible hair growing inside and outside its auricle, "They can monitor the human heartbeat, and any sudden heartbeat changes can attract their attention. Keep your breathing stable, which can help you deceive the vampire's search."

Roger slowly lowered his breathing rate and distracted himself by looking around.

The experimental subject in the cage was still sleeping and looked lifeless. The goblins walked in the corridor from time to time, making slight footsteps. Although some guys were sneaking around, the whole laboratory was still calm.

His position was very secretive, with a wooden board with torchlight shining through it above his head, a pile of ore on his left, and a door to the nearby laboratory on his right.

Hearing the conversation between the werewolves and vampires not far away, he secretly thought that he was lucky. If he had used a dagger to cut the throat of the goblin outside the cave, the strong smell of blood would definitely arouse the suspicion of the werewolves.

"But which Auror is secretly using perfume." Rogge muttered to himself, frowning tightly.

He closed his eyes and carefully felt the air around him. In this dim and turbid underground world, the strong tar smell of the torch almost covered everything. However, his keen sense of smell still caught a hint of unusual sweetness - it was the rare smell of caramel.

As an excellent potion master, Roger's sense of smell is comparable to that of a werewolf. Years of potion research have enabled him to accurately distinguish the various odor components in the air. He took a deep breath, as if tasting a complex magic drink, "cardamom, caramel, salt..."

"And vanilla, tobacco." He opened his eyes, slowly scanned the surroundings, and exhaled helplessly. This unique smell can only come from a certain perfume.

In a corner of the laboratory, the invisible Tonks didn't know that she had been exposed. The perfume she used: the unpredictable Constance, has exposed this group of uninvited guests.

The werewolf and the vampire exchanged a meaningful look. The tense atmosphere in the air suddenly became thick. The vampires above their heads began to wake up one after another, and their red eyes flashed dangerously in the dark.

Although the goblins were still patrolling as usual, Roger was keenly aware that the werewolves and vampires were moving silently to a corner. Their movements seemed random, but in fact they were moving step by step.

The images from the crow mask gradually converged on the werewolves and vampires. Roger understood that the Aurors also noticed the enemy's strange behavior.

Time passed by minute by minute, and the tension in the air was almost suffocating. Roger knew that if they did not take action, they would fall into an irretrievable situation.

"Fluorescent flash." He raised his wand without hesitation and chanted the spell in a low but firm voice.

The tip of the wand instantly burst into a dazzling light, like a white-hot sun that was suddenly born. The dazzling light instantly swept the entire laboratory and dispelled the darkness.

This sudden "holy light" not only illuminated the entire space, but also disrupted the enemy's deployment.

"Ah, my eyes!" A cry of surprise suddenly rang out in the laboratory.

Many people were caught off guard, their eyes were instantly drowned by the dazzling light, and their brains were occupied by pure white. They rubbed their eyes in panic, trying to restore their vision.

For the vampires, the situation was even worse. These creatures who loved the dark by nature let out shrill howls under the strong light of the fluorescent flickering.

They hurriedly crossed their arms to protect their eyes, curled up into a ball, and trembled like frightened mice. Some crickets tried to find shelter and escape from the piercing light.

"There are intruders!" The voice of the werewolf Yule suddenly sounded, reminding all the Death Eaters to prepare for battle.

He had rich combat experience and reacted the moment his eyes went blind. First, he bent down and rolled on the ground, hiding under the dining table just now. Then, while shouting a warning, he cast magic to seal off the entire laboratory.

"Damn bastard!" Many Aurors couldn't help cursing, "When I find out who put the fluorescent flickering, I have to kiss his ass hard with my boots."

They closed their eyes tightly, trying to restore their vision as soon as possible, and they didn't dare to relax their wands in their hands, ready to deal with possible attacks at any time.

Rogge couldn't help curling his lips when he heard his companions' complaints. He was the one who had the most right to complain. If it weren't for that damn perfume, how could he have exposed himself.

Ding ding ding... a sharp metal friction sound rang out, and the iron door of the laboratory fell down with a bang, completely isolating it from the outside world. At this moment, not even a fly can escape.

Rogge exhaled helplessly and declared in a loud and firm voice: "I originally planned to get along with you in a stealth way, but what I got in return was vigilance. I won't pretend anymore, I'm going to be invincible, and show my cards!"

As soon as he finished speaking, Youer's roar echoed in the laboratory: "At the door of Laboratory No. 14, attack! Attack! Come on!"

The temporarily blinded Death Eaters moved at the sound, but their movements of chanting spells were slow and chaotic. Many people couldn't even complete the trajectory of their wands, let alone find the target.

The expected fierce battle did not break out, only a one-sided beating. Rogge's wand swung as fast as lightning, and "Petrify All" accurately hit the mindless target.

Such a spell was enough to deal with a group of temporarily blinded enemies, and "Disarm Us" seemed too much.

"Damn it, if it was a full moon night, I would definitely kill you!" Yuer said cruelly, and immediately activated the Apparition and disappeared into the air.

"Haha, even if it is a full moon day, we choose to do it during the day." Rogge sneered and kicked over the dining table in front of him. Thinking that the Death Eaters can use the Apparition, a trace of helplessness flashed in his eyes.

He recalled the discussion before the operation. Because it was a secret operation, Dawlish had proposed to start at night. But Rogge insisted that it was more advantageous to act during the day.

First, the light conditions during the day are good, and it is easier to observe the enemy's movements. Second, most people's biological clocks follow the sun.

If the attack is at night, those night owls, vampires and werewolves will be energetic and sharp-minded, which will make them more difficult to deal with.

Now it seems that his judgment is correct. While stealth didn't quite work out as intended, operating during the day did give them a huge advantage.

An Auror who had regained his sight squinted his eyes and glanced at the Death Eater who was dealt with by Roger alone. He still couldn't help complaining: "Boy, I admit that your fluorescent flash is powerful, but can you give a heads-up next time? This is simply betraying your teammates!"

Roger raised his eyebrows and sneered: "Hehe, instead of worrying about my spells, it's better to check whose perfume smell is guilty."

"Perfume? How is it possible! All the wizards are here this time."

Another burly Auror shouted: "Kid, stop talking nonsense! Where does the perfume smell come from? We are all experienced old Aurors, how could we make such a low-level mistake."

"Really? But the werewolf just noticed it." Roger's eyes were fixed on a seemingly empty wall. His eyes became sharp, and his wand was raised instantly, and he whispered: "Expecto Patronus."

A silver-shining crow flew out from the tip of the wand, with its wings spread out, like a dazzling silver lightning. It swooped down to the shadow of the wall without hesitation, and its sharp claws pierced into the cracks of the stone.

In the astonished eyes of everyone, a hidden Dementor was pulled out by the Raven Patronus. The terrifying black shadow twisted and struggled in the silver light, screaming silently, and was torn into countless pieces in the blink of an eye and dissipated into the air.

"Damn it, this thing is really here. I thought Dawlish was just talking."

"Fortunately, someone has mastered the guardian spell." An Auror looked at Rogge and muttered, "Dementors will not be completely killed. They are born in fear and feed on fear. Even if they are dispelled, they will eventually re-condense from fear."

"Now is not the time to read by heart." Rogge pointed his wand at the closed door, and the fiery red beam was like an angry dragon's breath, instantly blowing the heavy door into pieces.

The smoke and dust dissipated, and a suffocating scene appeared before everyone's eyes.

Behind the door, there were hundreds of Death Eaters who had apparated. The dark wizards had bloodthirsty eyes on their hideous faces; the goblins showed their sharp teeth and held their wands tightly; the Dementors floated in the air, emitting a heart-pounding chill; the vampires licked their lips, as if they had already smelled the scent of blood.

At the same time, more Death Eaters appeared in the silver light of Apparition. They were densely packed, and looked like they were determined to kill all the invaders.

"You hurry up and save people, I'll open the way!" Rogge jumped down from the second floor, waving his wand like the wind, facing the enemy group in Laboratory No. 14.

If it weren't for the inexplicable perfume, it would be impossible to attract the Death Eaters outside the laboratory. Rogge could only spread his hands, expressing his helplessness to the pig teammates in the team, and then picked up the wand to go up.

As Dawlish often said, not all Aurors can really meet the requirements of this position. Things like opening backdoors and using connections are not uncommon in the Ministry of Magic.

His thoughts flashed through his mind, and at the same time, his wand kept waving, and a series of spells exploded among the enemy.

Rogge suspected that it was Tonks, the young witch who was born with the ability to transform. Her ability is indeed amazing, and she can easily disguise herself as someone else to collect intelligence in various occasions.

However, this does not mean that she is suitable to be a combat Auror. On the contrary, doing some intelligence work can better play her talent.

"Stupid!" He cursed, and at the same time, he used the stun to quickly knock down the four vampires flying over.

Knowing that there are werewolves among the Death Eaters, she did not remove the perfume on her body. Doesn't she understand that in this dark and turbid cave, the caramel-like sweet fragrance is like a beacon in the dark, pointing out the target for the enemy?

Rogge complained in his heart and put on armor to protect himself. The powerful magic made the protection spell shine with golden light, like an insurmountable barrier, rebounding the attacks of the Death Eaters one by one.

Men need to be durable, and Rogge's armor is particularly durable and indestructible.

"Crucia~" Suddenly, an almost imperceptible green light pierced the air, and the sound of the spell was so light that it seemed like a poisonous snake spitting out its tongue.

Rogge's crow mask instantly captured the deadly green light. He was startled and immediately realized that this was a premeditated attack. The cunning Death Eater cleverly hid the Unforgivable Curse in a colorful spell beam and attacked quietly from the right rear.
