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

Dumbledore looked into Su Yu's eyes and saw that he was serious and not joking. After thinking for a moment, he finally agreed.

And so, Su Yu once again became the Defense Against the Dark Arts professor at Hogwarts, but this year he was much more experienced than last year's chaotic situation.

Practice questions, exams, and real-world application – it's still the same old combination. Plus, with the Duel Club providing an excellent platform, Su Yu's teaching is incredibly effective.

In the days that followed, Gilderoy Lockhart's trial came to a close, and the carefully cultivated public image he had built over the years collapsed.

The shockwaves this caused in the wizarding world were even greater than when Peter Pettigrew was captured, after all, Peter Pettigrew was just an unknown traitor.

Gilderoy Lockhart, on the other hand, was a top figure in the British and even the entire European wizarding world, and an idol in the hearts of countless witches.

Similarly, thanks to the influence of Toutiao (a Chinese news aggregator), Arthur Weasley's reputation soared, making him second only to Fudge, the Minister for Magic of England.

Seeing the growing fervor for Arthur within the British magical community, Su Yu knew that he could begin to make his final move regarding Arthur.

It was another Friday, and Su Yu walked into the Duel Club as usual. His attire was similar to before, but the students would notice that three crows were flying around him.

The three crows would sometimes transform into silver metallic material, sometimes into living crows with black feathers, and sometimes into fire crows, repeating this cycle every few minutes.

This is a training method that Su Yu has recently researched, mainly to complete his epic proof mission for shapeshifting.

The requirement of undergoing tens of thousands of transformations was an extremely large number for Su Yu. After numerous experiments, this training method is currently the optimal solution that Su Yu has found.

It not only meets the mission requirements but also allows Su Yu to have precise control over magic, and it looks very cool.

However, he can only maintain this training method for a maximum of 3 hours a day; any more than that would severely deplete his physical and mental strength.

The young wizards were very excited to see Su Yu arrive. Su Yu's sparring with them for half a year last year had greatly benefited the little guys, and Su Yu would go easy on each young wizard according to their strength.

The main principle is: if I feel you are stronger than last time, I will let you win. The students gradually discovered this pattern, and each of them used the number of times they defeated Su Yu as something to brag about.

During this process, Su Yu also recruited several sixth and seventh grade students for Raven Feather. According to Su Yu's plan, these students would be placed in the Ministry of Magic or in the experience stores of various countries of Raven Feather after graduation.

Su Yu put away the crows beside him, walked to the center of the dueling arena, pressed his hand in the air to quiet the children, and said, "Same rules as before, fifty challenges. As long as you can make me move, you win."

Gemma Farley stood at the entrance, holding a small notebook in her hand. She had already registered all the challengers who had signed up for the day. She read out, "Today's first challenger is Oliver Wood from Gryffindor!"

As soon as Gemma Farley finished speaking, the Gryffindor audience in the stands outside the stadium cheered, including Harry, Harry, and his trio.

Ron exclaimed excitedly, "Harry, how many seconds do you think Captain Wood can last this year?"

Harry said, "During training today, Captain Wood said he was sure he could beat Professor Sue."

Hermione scoffed, "He always says that, but he's actually defeated Professor Sue more times than I have."

Su Yu stood there quietly, like a peerless master. His current record in the dueling arena is 396 wins and 387 losses.

For the past six months, Su Yu has played 50 matches in each Duel Club, and kept each match under 30 seconds, naturally aiming to earn the Duel King and the "The More You Fail, the Stronger You Become" achievement.

Unfortunately, the next stage of achievement is still a long way off. He looked at Wood as he entered the arena and said, "You can launch an attack at any time."

Wood didn't hold back. This wasn't his first time challenging Su Yu, and he was very experienced. He immediately launched a petrification spell.

The red spell arced towards Su Yu, but Su Yu's reaction was simple: with a flick of his wrist, he deflected Wood's spell back.

This technique was naturally something Su Yu figured out after six or seven hundred duels. It was essentially an application of the Ironclad Curse, and he could now use it with ease.

Wood had anticipated this, and when the spell flew back, he cast another Explosion Spell. The two spells met in mid-air, bursting into a huge burst of dazzling light that blinded the audience.

Taking advantage of the opportunity, Wood quickly moved to the right front, and even did a forward roll. After getting up, he immediately cast a binding spell.

A rope flew out with a spell, shooting towards Su Yu. Unfortunately, Wood thought he could use the dazzling light to distract Su Yu's vision, but in fact Su Yu had already seen everything.

With a flick of the wand, a bolt of lightning the thickness of a thumb shot out from the tip of the wand, blasting the rope into dust, and its momentum continued unabated as it rushed toward Wood.

Sure enough, it was the lightning spell. Wood was overjoyed. He had been defeated by this very move last time. Fortunately, he had been paying attention in the Muggle Studies class this week.

Wood tapped his wand lightly on his left arm, and a huge rubber shield appeared. Lightning struck the shield, making a crackling sound.

It even left black scorch marks on the shield, but it could never harm Wood behind it.

Wood secretly gathered his strength, and after the lightning spell ended, he immediately thrust out his wand. A wooden spike shot out from the wand and flew towards Su Yu.

Chapter 137 Achievement Farming (Part 2)

As the wooden splinter hurtled toward him, Su Yu had dozens of ways to deal with it, but judging by the time, the match had already lasted 26 seconds and should be over.

Su Yu moved his feet and dodged the wooden spike. Seeing Su Yu move, Wood jumped up and waved his arms, showing five fingers, indicating that this was his fifth victory.

The young Gryffindor wizards immediately cheered with joy, and Ron said to Hermione, "Captain Wood has caught up with your record."

"What's there to be happy about? If I remember correctly, your record against Professor Sue is 2 wins and 7 losses!" Hermione retorted mercilessly, making Ron blush.

At this point, Gemma Farley continued, "The next challenger, Hermione Granger!"

Hermione proudly raised her head and said to Ron, "Hmph, watch me go and win again."

"You think you can just win like that?" Ron retorted.

Hermione entered the dueling arena, and Su Yu was still standing there, one hand behind his back and the other holding his wand, hanging slightly down, like a swordsman.

Hermione is now in her second year and has learned many more spells; she can unleash a flock of birds with a wave of her hand.

With a whooshing sound, forty or fifty sparrows flew out quickly, flapping their wings and rushing towards Su Yu.

Su Yu remained calm and composed. He twirled his wand in the air, pointed forward, and a cloud of mist drifted away to meet the oncoming bird.

When the birds collided with the mist, the birds that had been flapping their wings suddenly stopped and turned into pieces of black wood carvings.

With a series of thuds, the wooden carvings fell to the ground like dumplings being dropped into a pot, then quickly took root, sprouted vines, and even blossomed.

Su Yu's move was purely a display of skill, causing the young wizards in the surrounding stands to gasp in amazement. Hermione also used the birds and plants as cover to get to Su Yu's side.

Hermione waved her wand and shouted, "Fluorescence!"

Then, suddenly, a burst of intense, dazzling light erupted from the tip of Hermione's wand. The light was so intense that it resembled a flashbang, causing all the young wizards in the room to instinctively cover their eyes.

Su Yu hadn't expected that this little girl would choose to use a spell like Fluorescent Blink, which had absolutely no offensive power.

Even more unexpectedly, Hermione's Flurry could compress magic to such an extent. Whether in terms of spellcasting skills or combat acumen, Su Yu could give Hermione a passing grade.

However, Su Yu's glasses already had the function of preventing glare, so this trick was really useless against Su Yu.

Then, Hermione pointed her wand at Su Yu again and said, "Tarantella Dance!"

This time, a pink spell was fired, also known as the Dancing Spell. Once under the spell, the legs will become uncontrollable, and the user will start dancing wildly.

It was another unexpected spell. This spell was usually used by young wizards as a prank, but Hermione's goal was to make Su Yu move, so this trick was very suitable.

At this point, Su Yu could have already admitted defeat, since he was quite satisfied with the assessment. However, Su Yu suddenly had a mischievous urge to see what Hermione would look like doing tap dancing.

So it was another use of the Ironclad Curse to deflect Hermione's curse. Su Yu even thought this move could be called "Shifting Stars," as it deflected Hermione's curse back.

Hermione had clearly anticipated this outcome as well. Unhurriedly, she continued to cast the Transfiguration Charm, transforming the vines Su Yu had just conjured into a large snake.

The Dancing Spell was cast on the giant serpent, which, because it had no legs, began to writhe wildly in the arena.

"Wow, Hermione! You really surprise me. Has Transfiguration been used to this extent?" As a Level 10 Transfiguration master, Su Yu greatly admired Hermione's spell just now.

Hermione snapped, "It's not over yet!"

As she spoke, Hermione continued to use Transfiguration, and the writhing snake transformed once more into a two-meter-tall wild boar, which, following Hermione's instructions, charged directly at Su Yu in a savage attack.

"Alright, alright! You win!" Seeing the giant wild boar, Su Yu quickly moved aside and said to Hermione.

Gryffindor erupted in cheers again, but Ron's expression was somewhat awkward.

“Hey Ron, don’t be like that! Hermione’s great!” Harry patted Ron on the shoulder.

Ron nodded, but still said, "I know she's great, but if she's always this good, it makes us look silly."

Next, Ron, Harry, and others also took to the stage to fight against Su Yu. An hour later, Su Yu successfully increased the number of attempts for both achievements to over 400.

Su Yu's skills are getting higher and higher, but he feels increasingly that skill points are scarce. He hopes to increase his magic power so that he will be more confident in facing either Dracula or Voldemort.

When the dueling club ended, it was already 9 p.m. The children returned to their respective dormitories to rest, but Su Yu did not go back to his office. Instead, he took Coal Ball and secretly left Hogwarts Castle.

Su Yu first went to Hogsmeade Village, where he met up with Lupin and Timothée, and then went to the Burrow to meet up with Arthur, Kingsley, Tonks, and others.

"Su, is everything you said true?" Seeing that Su Yu had finally arrived, Tonks couldn't help but step forward and ask.

"When have I ever lied to you?" Su Yu asked instead of answering, and casually ruffled Tonks's hair. The girl had changed her hair to dark red waves today, which added a touch of mature charm.

Arthur then spoke up, "Su, this time is different from before. Even if we arrested the wrong people, we just released them and apologized at most."

"But with this guy's influence, if we arrest the wrong person, we'll really be out of a job at the Ministry of Magic!"

Su Yu's expression also became very serious: "Arthur, we've cooperated so many times, you should know my character. I can take responsibility for the information I provide!"

“Of course we believe you… but…” Kingsley said before Arthur could speak, “This is a huge matter. I just think we should slow down and get more accurate evidence.”

"Don't worry, the evidence is in their manor. As long as we storm in and take them all down, we'll catch them red-handed!" Su Yu said confidently.

Seeing Su Yu's persistence, Arthur was somewhat moved. He knew in his heart that the biggest beneficiary of all that Su Yu had done was none other than himself, Arthur Weasley.

If this succeeds, Arthur will almost certainly become a director!

Others might doubt Su Yu, but Arthur couldn't. So he clapped his hands and said, "Alright, everyone, I believe in Su. If anyone still has doubts, they can stay and wait. The rest of you, get ready, let's go!"

Chapter 138 Crouch Manor

“I also believe in Su Yu! I’ll participate in the operation!” Tonks was the first to step forward and express his opinion.

As a result, everyone in Kingsley's team turned to look at her and couldn't help but laugh. Kingsley joked, "Oh my, our little Tonks knows how to protect her boyfriend now!"

"Hahaha!" The rest of the team laughed, making Tonks blush and breaking the somewhat awkward atmosphere.

Kingsley continued, "Alright, in that case, let's set off together!"

……

In an old manor on the outskirts of London, Barty Crouch, having finished his day's work, came to a secret room where a person was locked up.

This man was about thirty years old, with blond hair and a handsome, sunny appearance, but his eyes looked somewhat dull.

Just then, a house-elf wearing a tuxedo and with an exceptionally long nose walked in from outside carrying food and said, "Sir... would you like some more?"

This little sprite is called Sparky, and it is the house-elf of Family Crouch. As one of the twenty-eight pure-blooded holy races, Family Crouch naturally has a very deep foundation.

Barty Crouch glanced at Sparkle and said, "No need. Has he shown any unusual behavior today?"

"No...no, sir! Young master is perfectly fine today," Shan Shan said, bowing her head.

Old Barty's eyes were complicated. Calculating the time, Little Barty's Soul-Stealing Curse would be about to expire in the next day or two. He came here today to cast another Soul-Stealing Curse on his son.
