I've already become a Hogwarts professor, and the system only just appeared.

For twelve years, he has been controlling his son with the Imperius Curse. Twelve years ago, he was the Director of the Department of Magical Law Enforcement and a leading candidate for Minister of Magic.

During the capture of the Death Eater remnants, Igor Karkarov revealed a name: Barty Crouch Jr.

At the time, Barty the Elder was the presiding judge, and he had to personally arrest his son. After the trial, Barty the Younger confessed to his crimes and was sentenced to life imprisonment.

For the sake of her son, Barty Crouch's wife drank Polyjuice Potion, impersonated her son, and eventually died in Azkaban. For the past twelve years, the whole world has believed that Barty Crouch Jr. is dead.

But in reality, Barty Jr. still stayed at the Crouch family manor. Although he was alive, Barty Jr.'s heart belonged only to Voldemort. He always hoped to find the Dark Lord and let him rule the wizarding world again.

To prevent his son from being exposed, to ensure his wife's death wasn't in vain, and for the sake of his own career, Barty Crouch, after failing to persuade him otherwise, had no choice but to resort to the extreme method of the Imperius Curse.

The Imperius Curse, one of the three unforgivable curses, allows the caster to completely control another person's mind, making it extremely powerful.

However, as the spell is cast frequently, the person being cursed will gradually develop resistance, causing the spell to take effect for a shorter and shorter time.

Initially, Barty Crouch Sr. could control his son for two whole months with a single Imperius Curse, but twelve years later, the effect of an Imperius Curse only lasts for about 10 days.

Old Barty was very worried about this. He knew that one day his son would get out of his control, and then he might face death.

While he was thinking, the young man in the secret room suddenly moved. He stuck out his tongue nervously and twisted his neck slightly.

But old Barty didn't see it; he was still lost in his memories, while little Barty's neck began to twitch rapidly.

Suddenly, Little Barty stood up, raised his hand and pointed at Old Barty. A silent, staffless petrification spell flew from his fingertip and shot towards Old Barty.

Old Bati was awakened by the flashing red light and instinctively tried to activate his armor to protect himself, but it was obviously too late. Old Bati knew that once he was petrified, he would definitely lose control of his son.

At the critical moment, Flash stepped forward and unleashed a spell that collided with Barty's Petrify Spell. The spell veered off course and grazed past Barty's face.

"Young Master! You mustn't hurt Master!" Shan Shan said to Little Barty.

Barty the Elder, a former Auror and former Director of the Department of Magical Law Enforcement, possessed formidable combat awareness. He immediately unleashed a Flashpoint Charm, sending Barty the Younger flying.

"Master, please don't do this, the young master will get hurt!" As a house-elf, Shiny was in great pain seeing his two masters at odds, but obviously no one cared about him.

Slumped against the wall and on the ground, Little Barty's lips curled into a smile, his tongue twitching unconsciously as he said, "Hehe, old man, soon you won't be able to control me anymore. Your Soul-Stealing Curse will only make me stronger."

Old Barty, his face contorted in anguish, pointed his wand at his son: "Why, why? The Dark Lord is dead! Why are you still so stubborn?"

“Death? Hahahaha…” Little Barty seemed to have heard a funny joke and continued, “Foolish old man, you have no idea how great Master is. He will never die!”

"He won't die? He's been gone for twelve years. If he's not dead, where has he been for those twelve years? Why doesn't he continue his dark reign?" Old Barty roared.

At this moment, Little Barty reached up and pulled up the sleeve of his left hand. A wisp of magic flowed into it, and a snake-shaped mark appeared on it. His expression turned ferocious, and he laughed:

"See that? Old man! The Dark Mark is still there. This means our master isn't dead. He'll come back and rule the entire wizarding world. You will all eventually submit to him, hahahaha..."

Seeing Little Barty's manic laughter, Old Barty closed his eyes. He knew his son was doomed, and so was his family: "Soul out of body!"

A dark blue spell shot from the tip of Barty the Elder's wand and struck Barty the Younger. The next moment, Barty's face contorted in extreme pain as he struggled desperately to resist.

However, his current willpower could not counteract the curse. About two minutes later, Barty Crouch Jr. returned to silence, his eyes becoming numb again, as if he had lost his soul.

"Shanshan, put the food in!" Old Barty said with a deep breath and a helpless expression.

"Yes...yes, sir!" Flash bowed respectfully, went in and placed the food on Little Barty's table, then helped Little Barty up from the ground and cleaned the dust off his body.

Little Barty stood there motionless like a robot until Old Barty spoke up: "Sit down and eat!"

Then, as instructed, Little Barty sat down and began stuffing the fried fish and chips from the plate into his mouth, bite by bite.

Looking at his son like this, old Barty couldn't help but wonder if living like this was really living. Perhaps he should give him a quick death. But after hesitating for a long time, old Barty didn't raise his wand again and finally turned and left.

Suddenly, seven or eight figures appeared outside Crouch Manor via Phantom Teleportation.

Chapter 139 Crouch Manor

The group that arrived was none other than Su Yu and his party. They quietly approached the outskirts of Crouch Manor. Su Yu activated the detection device on his glasses and quickly discovered that there was powerful protective magic outside the manor.

He held out his hand and said, "Wait a minute. There's protective magic. If we rush in, we might activate the magic circle."

Kingsley said, "Of course, the Crouch family is one of the Twenty-Eight Pureblood Holy Clans, so their defenses are definitely not bad."

"However, for an ancient family like this, there must be anti-apocalyptic spells in the manor. As long as we rush in, they will most likely not be able to escape."

Su Yu looked at Kingsley and found the guy a bit funny, saying, "I'm afraid their little elves will have already teleported Barty Crouch Jr. before we even get in."

"When we have no evidence, how will you explain that we suddenly broke into the home of the Director of the International Magical Exchange and Cooperation Department without a search warrant or arrest warrant?"

"Then what do you suggest?" Kingsley was speechless after being rebuked, but still stubbornly retorted.

Su Yu ignored Kingsley and instead pressed his glasses a few times, carefully examining the Crouch family's defensive magic circle.

Su Yu had some knowledge of magic circles, after all, he had spent nearly two years at Hogwarts Castle, not counting his school years.

Hogwarts Castle boasts the world's most advanced defensive magic arrays, providing a top-tier reference point. Crouch's little gadgets are nothing compared to that.

About fifteen minutes later, Su Yu had figured out the magic runes. He took out his magic wand and waved it.

The next moment, at the edge of Crouch's defensive magic circle, the soil on the ground continued to gather and turn into a silver metal rod, with one end outside the magic circle and the other end inside.

This is also a combination of Su Yu's transformation magic and alchemy. While transforming, he modifies the transformed object with magical runes, giving the transformed item a magical effect directly.

The effect of this stick is to block and simulate. It can pass through the magic pattern net of the magic defense array, thereby blocking the detection of the magic patterns within, while simulating the reactions of the magic patterns within, making the defense magic array think that it is operating normally.

Upon seeing the stick, everyone was delighted. A stick had passed through the defensive magic circle without triggering it, indicating that Su Yu had broken through the defense mechanism. Now, it was up to him to see how he would get everyone through.

Su Yu continued waving his wand, chanting incantations, and continued to cast his shapeshifting alchemical magic. The silver metal rod grew taller and wider.

Finally, a metal door formed directly on the defensive membrane of the defensive magic circle. Su Yu easily opened the door and said, "Alright everyone, please come in!"

This scene naturally stunned everyone. Arthur couldn't help but give Su Yu a thumbs up and said, "Wow, Su, your magical skills are getting more and more amazing."

The group filed in through the metal door. Su Yu took out a photo from 12 years ago and instructed, "Teemo, take Coal Ball and find Crouch first. Keep an eye on him and don't let their little elves take him away."

"Yes, Master! Timo guarantees to complete the mission!" After saying that, Timo mounted Coal Ball and rode off into the manor.

Then Su Yu looked at the others and said, "Alright, our next task is to control this old Mr. Barty Crouch!"

Crouch Manor was large and not heavily guarded. Although the family was dwindling in number, Barty Crouch the Elder still hired a number of guards to protect himself and the family.

Some of them were former Aurors, and some were champions in magical duels. No matter what kind of society it is, money always brings many advantages.

The group dealt with the guards one by one, not by killing them outright, but by using petrification or stun spells to temporarily render them incapacitated.

Things were going smoothly at first, and everyone was making their way to Barty Crouch's room at a steady pace. But Tonks was still too young. He made a careless move, and the Sleeping Curse wasn't powerful enough to take down his opponent.

"Expelliarmus!" The security guard shook his groggy head, flicked his wand, and a red spell shot towards Tonks.

Su Yu reacted the fastest, rushing out to block Tonks, and then using a move called "Shifting Stars" to deflect the disarming spell back.

Then Su Yu followed up with another petrification spell. The security guard was knocked away by the disarming spell and was completely petrified in mid-air before he even landed.

Even though Su Yu moved quickly, his actions had already attracted the attention of others. One of the security guards immediately raised his wand and fired a warning spell into the sky.

A major battle was about to break out. Su Yu shouted, "Charge! I'll go in and take control of Old Barty. You guys deal with these guys outside and hold off the Ministry of Magic's rescue efforts."

The Ministry of Magic rescue that Su Yu mentioned could not possibly be a rescue for them, but rather a rescue for Barty Crouch, the current Director.

"I'm sorry, Sue! It's all my fault!" Tonks said, looking aggrieved.

But Su Yu didn't have time to pay attention to her at this moment. He said "It's okay" and rushed out in the direction of his target.

At this moment, the two sides had already clashed, spells ripped through the night sky, and various colored lights flashed incessantly.

After more than 800 wizard duels, Su Yu's combat reaction has improved significantly. He can nimbly dodge or block spells coming from all directions, and can also launch a certain degree of counterattack.

Crossing the line of fire, Su Yu quickly arrived at Barty Crouch's study. He saw a fleeting glimpse of Flashy Shadow, then Barty Crouch pointed his wand at Su Yu and said:

"Who are you, daring to trespass on Crouch Manor? Do you know that I am the Director of the International Magical Exchange and Cooperation Division of the British Ministry of Magic? Do you know what crime you are committing?"

Su Yu was not to be outdone and said with a smile, "Of course I know Mr. Crouch's name, but Mr. Crouch, do you know what crime it is for a director to privately protect Death Eaters and switch Azkaban prisoners?"

"I don't know what you're talking about!" Barty Crouch's heart skipped a beat, and he quickly denied it, brandishing his wand: "Expelliarmus!"

"Disarm you!" Su Yu also used a disarming spell, but since it is said that the left side loses in a battle, and Su Yu happened to be standing on the left.

Old Barty's spell shattered Su Yu's spell, but its momentum remained undiminished as it continued to shoot towards Su Yu. To be on the safe side, Old Barty added another shot: "Petrify them all!"

Su Yu's expression was somewhat solemn. He knew that the reason he lost the previous duel was certainly not because he was standing on the left.

It was because, in terms of both magical power and spellcasting skills, this former Director of the Department of Magical Law Enforcement was far superior to him; he had been completely overwhelmed.

Chapter 140 Standoff

Faced with the relentless petrification curse, Su Yu remained calm. The three silver ravens on his chest flew out automatically, two circling around him, while the third charged towards the petrification curse.

As the raven flew, its body grew larger and larger, and it kept spinning. With a flap of its wings, it knocked away the petrification spell, which had lost much of its power.

Then the raven continued to spin, its speed increasing, like a giant cannonball, charging towards Barty Crouch on the other side.

Old Barty frowned. Although he had been in a high position for many years and had few opportunities to fight, his experience as an Auror in his youth was not for nothing.

With a wave of his wand, the table in front of Old Barty quickly twisted and transformed into a giant vine. At the tip of the vine bloomed a flower made of metal, which swooped down on Su Yu's raven.

Su Yu was startled. A transformation technique that combines matter and life. It seems that this old man's transformation technique is not to be underestimated!

With a bang, the raven crashed into the metal flower. The flower's petals quickly closed, enveloping the raven as if to swallow it whole.

Then, with a loud bang, the flower enveloping the raven exploded, sending red flames flying everywhere. Finally, it coalesced back into a raven, flapping its wings and sending countless fiery feathers flying like darts toward Old Barty.

Old Barty was prepared. He waved his wand repeatedly, and the destroyed flower seemed to turn into a high-pressure water gun, spraying out a large amount of water to block the fiery feathers.

That wasn't all. After the water curtain blocked Su Yu's attack, it coalesced again and transformed into a giant water serpent in the air, opening its blood-red maw and lunging at Su Yu.

Su Yu originally thought that since he had raised his Transfiguration skill to LV10, the only people in the British magical world with a higher level of Transfiguration skill than Professor McGonagall and Dumbledore were him.

I never expected that this old man in front of me would be no less capable than myself. I underestimated the heroes of the world.

Of course, Su Yu was not flustered. He waved his wand, and the two little ravens beside him quickly expanded into two giant fire crows.

Then the three fire crows in the air merged into one. Their size didn't change much, but the quality of their flames did improve, turning into a deep blue.

The water snake and the fire crow collided in mid-air, and the water snake was quickly vaporized, after all, Su Yu's fire crow was not just transformed by shapeshifting magic.

These three fire crows have undergone several iterations of alchemy techniques, and their materials are already very special. When they are turned into metal, they are incredibly hard and can be immune to some magic, just like a bouncy pot.

When they become living beings, they are highly intelligent and can make their own judgments to attack or defend.

When transformed into an element, the internal magic patterns are interconnected and superimposed, which can amplify its power many times over. The water snake that Old Barty conjured was no match for it.

However, Barty the Elder wasn't just skilled in Transfiguration; his dark magic was equally formidable. With a wave of his wand, he shouted, "Fiendfyre!"

The next moment, dark red flames spewed from Old Barty's wand, transforming into a firebird that rushed towards Su Yu's Flame Raven.
