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

With everything ready, the Weasleys began to cross Platform 9¾ one by one, first Percy, then the twins, with Arthur and Molly on either side, escorting Ginny inside.

Finally, only Harry and Ron remained outside the platform. The two boys looked at each other, their faces lighting up with excitement, and then pushed their suitcases, crashing into the wall.

With a bang, Harry and Ron were knocked off their feet and fell onto the platform, attracting the attention of the surrounding Muggles. A kind train conductor even came over to inquire about their whereabouts.

In a corner not far away, Dobby banged his head against the wall several times, muttering to himself:

"Dobby is a bad elf. Harry Potter was so good to Dobby, but Dobby made him fall. Dobby should be punished."

"But Hogwarts is in danger, and Dobby must stop Harry Potter from returning to Hogwarts. I'm sorry, Harry Potter, Dobby has to do this!"

After saying that, Dobby was about to snap his fingers and teleport back to the Malfoys' house. After all, he had secretly run away while Lucius was taking Draco to school, and if he were discovered, he would be doomed.

Just then, Dobby's hand was grabbed by another small hand, and in front of Dobby appeared a house-elf dressed in a gorgeous tuxedo.

Dobby had never seen a house-elf dressed so elegantly, his skin so smooth, his eyes so bright, that Dobby forgot to resist at first.

The little sprite that appeared was Teemo, who grabbed Dobby's hands with both of his, a smile playing on his lips, and said, "Got you!"

It was only then that Dobby realized he had been discovered. He didn't know who the other person was, but Dobby felt he had to escape as soon as possible, or he would be in serious trouble.

He prepared to continue using Apparition; there were too many people at King's Cross Station, and if a fight broke out there, Muggles would definitely see it.

But Teemo wasn't about to let him have his way. When it came to interrupting Io's Apparition, Teemo had a say.

In Dobby's vision, a shiny, large head rapidly magnified and slammed into his forehead with a loud bang.

Dobby was a little dizzy and wanted to fall backward, but his hand was grabbed and he involuntarily fell forward again.

With a bang, another headbutt landed, and Dobby was hit hard again. But perhaps because Dobby often punished himself by banging his head against things, he had high resistance to headbutts.

Teemo's second headbutt not only failed to stun him, but also woke Dobby up. Taking advantage of Teemo's third attack, Dobby kicked Teemo away.

Chapter 83 The Interrogation of Tobirga

Teemo rolled on the ground, emerging from the corner and into the view of several Muggles.

Fortunately, Lupin reacted quickly, pulling out his wand and casting a wide-area Confusion Charm, causing the surrounding Muggles to subconsciously ignore Teemo.

At the same time, Lupin arrived beside Harry and Ron, who were already sweating profusely and were about to drive Arthur's car to chase after the train.

This was precisely why Su Yu had arranged for Lu Ping to guard the two kids here. If those two kids really drove a flying car over London, then the persona he had built for Arthur over the past month would collapse, and Arthur's career would be over as well.

So, whether in China or the UK, there are always mischievous kids willing to cause trouble for their parents.

"Hello, I'm Remus Lupin, the factory manager of the Feather Magic Phone manufacturing plant. Do you need any help?" Lupin asked while secretly observing the battlefield between Timo and Dobby.

Ron reacted quickly, flipping through Toutiao (a Chinese news and information platform) and soon finding Lupin's photo: "Oh my god, it really is you, Mr. Remus! It's a pleasure to meet you!"

Harry was much more pragmatic than Ron, and pleaded, "Mr. Lupin, we are second-year students at Hogwarts, and we can't get onto Platform 9¾. Can you help us?"

Lupin said, "Of course you can. Do you have magic phones? You can send a message to your parents first."

“I’ve already sent it, but they’re probably busy right now!” Ron said, sounding a little aggrieved. “By the time they remember us, the train might have already left.”

"It's alright, don't worry. You two stay here for now. If the train leaves, I'll take you to Hogsmeade Village." Lupin patted the two on the shoulder and gave them a reassuring smile.

Then Lupin got up and walked quickly toward the battlefield. Just as the three were chatting, the situation on this side of the battlefield changed again.

After being kicked away, Teemo looked up and saw Dobby preparing to use Apparition again. However, capturing Dobby was the first task given to him by his new master, Su Yu, and Teemo could not let his new master down.

He immediately reached out and, through the spellcasting ring on his hand, released a petrification spell. The yellow spell flashed and flew to Dobby with a long tail.

Dobby naturally dared not continue Apparition. Even though the house-elves' talent in Apparition was comparable to that of the phoenix, it was impossible for them to force the spell while under the effect of the Petrify Curse.

Otherwise, if hit, the person would be decapitated during the phantom teleportation. Dobby deftly dodged Teemo's spell with a side roll.

However, by the time Dobby got up, Teemo had already appeared in front of him, performing the exact same stomp move that Dobby had just made.

With a bang, Dobby was kicked away and fell into the railway tracks. Timo seized the opportunity, jumped down and tackled Dobby, grabbing Dobby's hand with one hand and wrapping the other around Dobby's neck to choke him.

Just then, a train pulled into the station, and the two little sprites were about to be hit by the train. Teemo, along with Dobby, used Phantom Teleport to arrive at Su Yu's side.

Su Yu acted quickly, and before Dobby could resist, a collar was put around Dobby's neck. This was also Su Yu's invention, called the Magic Stasis Collar.

It's mainly based on the reverse research of Tonks' previous magic being imprisoned, and its effect is similar, roughly preventing the normal flow of magic within wizards or magical creatures.

From afar, Su Yu waved to Lupin, indicating that he had succeeded. Lupin received the signal and then left the station with Harry and Ron.

Su Yu then brought Dobby to his home in London. He didn't rush to interrogate Dobby, but first had Timo pour Dobby a glass of water before asking, "What's your name?"

Dobby was a little scared, curled up, and kept trying to back away, but Timo was right behind him, like a guard, blocking Dobby's way.

“I…I’m called Dobby…” Dobby said in a very low voice.

As expected, Su Yu tried his best to appear kind and approachable, saying, "Don't worry, I don't mean any harm. Let me introduce myself. I am a professor at Hogwarts, and my name is Su Yu."

Su Yu once again took out his teaching certificate to prove his identity to Dobby. The little Pokémon relaxed a bit after seeing the certificate and was no longer so resistant.

Upon seeing this, Su Yu's tone turned serious: "Harry Potter told me that you stole his magic phone, cut off all his external communications, and just now you even tried to stop him from entering Platform 9¾ to return to Hogwarts. Do you know what crime the Ministry of Magic would sentence you for doing these things?"

"Wah!" Dobby was clearly terrified and burst into tears. "Dobby is a bad elf! Dobby is guilty! Dobby sneaked out without his master's knowledge and hurt Harry Potter! Dobby should have his head chopped off!"

After sobbing for a while, Dobby slowly raised his head and looked at Su Yu with his big eyes: "But Dobby didn't mean any harm. Dobby just wanted to help Harry Potter. It would be dangerous for him to go back to Hogwarts."

"Danger? What kind of danger? Tell me in detail." Su Yu continued to guide Dobby.

Dobby looked around cautiously: "Dobby knows that a dark magic item will be sent to Hogwarts Castle. It can open the Chamber of Secrets in Slytherin and release a terrible monster that will devour all non-pure-blooded wizards."

"Isn't Harry Potter a pure-blood wizard? His parents were both wizards, weren't they?" Su Yu asked curiously.

"Dobby doesn't know, but Dobby has heard that Harry Potter's bloodline isn't pure. His mother is a mud... Muggle-born wizard who will definitely be eaten by monsters, so Dobby has to stop Harry Potter from going to Hogwarts." Dobby said what he knew.

Next, Su Yu got to the point: "Dobby, who told you all this?"

"Dobby...Dobby can't say, can't say!" Dobby seemed to remember something terrible. He raised his hands to cover his face, as if danger was about to strike at any moment.

Su Yu had already anticipated this situation. House-elves cannot utter any disrespectful words towards their owners, nor can they even mention their owner's name. However, Su Yu had a solution, saying:

"Since you can't say it, then I will say it. You just need to nod or shake your head, okay?"

“Yes…yes, Professor Su!” Dobby said timidly.

"You're a house-elf of the Malfoy family, aren't you?" Su Yu asked.

Dobby shuddered involuntarily upon hearing the name Malfoy, then looked at Su Yu with disbelief. After hesitating for a long time, he finally nodded.

Su Yu was satisfied and continued, "So, the one who wanted to send this dark magic item to Hogwarts was Lucius Malfoy? Is that right?"

Chapter 84 Interrogation of Dobby

“No, it wasn’t Master!” Dobby quickly shook his head and explained, “Although Master was also… he didn’t want to send that thing to Hogwarts. Someone… someone asked him to do it!”

Su Yu raised an eyebrow: "Oh? Who is that person?"

Dobby continued to shake his head: "Dobby doesn't know. The man was wearing a black robe and a mask. Dobby didn't see his face."

Could it be other Death Eaters who haven't been captured? Su Yu searched his memory. Who could it be? Goyle, Crabbe, or McNeil?

"What did he say to Lucius Malfoy at that time?" Su Yu continued to press, regardless of who the other party was, what they said was the most important thing.

"Dobby, Dobby dares not say!" Dobby shrank back and said tremblingly.

Su Yu squatted down, patted Dobby on the shoulder, and said earnestly, "Dobby, you should have guessed it by now. Harry Potter has returned to Hogwarts. I am a teacher at Hogwarts, and I will protect his safety."

"But there's one condition: I must know the truth of everything, otherwise my actions will be greatly restricted, so I hope you will tell me everything you know."

“I…I…” Dobby took two deep breaths, as if he had mustered up a lot of courage, and said, “The man in black robes told the master…that the man whose name cannot even be mentioned told the young master to send his things that he had entrusted to the Malfoy family to Hogwarts Castle.”

"That thing will choose the young master to be Slytherin's successor, open the Chamber of Secrets left by Slytherin, grant the young master great power, and release the monsters in the Chamber."

"So Voldemort actually chose Draco Malfoy?" Su Yu asked in surprise.

"No...please don't mention that person's name, Dobby can't bear to hear it." Dobby covered his head in fear, and after a while, he said, "That person did choose the young master to do this, but the old master thinks it's too dangerous, and he's preparing to find another successor."

So that's how it is. Su Yu finally understood. This was Voldemort's plan. It made sense, since it was Voldemort's Horcrux. How could he just hand it over to a student? Draco was indeed the perfect choice.

What Voldemort didn't expect was that Lucius Malfoy's love for his son overcame his fear. Although he still carried out the order, he didn't do it exactly as Voldemort asked.

So Su Yu asked the last question: "To whom did Lucius give that thing?"

"I don't know. My master didn't like me. That's all I know," Dobby said apologetically.

Su Yu patted Dobby again: "Dobby, thank you so much for your help. You've given me enough information. Leave Harry Potter's safety at school to me!"

As he spoke, Su Yu helped Dobby remove the restriction. Dobby stretched his neck and asked, "Can you guarantee that I can go to Hogwarts to visit Harry Potter?"

"Of course you can, but you'd better not do anything dangerous on your own. You can communicate with me anytime if you have any questions." Su Yu nodded.

"Thank you, Professor Su. I have to go back now, or my master will find out I ran away on my own." Dobby bowed to Su Yu one last time, snapped his fingers, and left.

After seeing Dobby off, Su Yu and Timothée returned to Hogsmeade Village. Lupin had already handed Harry and Ron over to Professor McGonagall, and Su Yu had also informed Arthur and Molly. Everything was peaceful.

Upon seeing Su Yu, Lupin eagerly asked, "How did it go, Su? What did you find out? Is this related to Voldemort?"

Su Yu nodded and relayed all the information Dobby had given Lupin. Lupin's brows furrowed, and he slammed his fist on the table, saying:

"Why is it that Potter and Lily gave their lives, yet still couldn't kill that guy? Are we ultimately destined to be unable to defeat him?"

Su Yu comforted him, "Don't be like that, Remus. No one is invincible, not even Dumbledore. We need to understand our opponents better so that we can make the right choices."

With nothing much going on at the mobile phone shop, Su Yu returned to Hogwarts. He originally intended to go find Snape to see if the guy knew anything inside information.

But as soon as he entered the school, he was caught by someone. This person was wearing a gorgeous golden wizard's robe and a forget-me-not blue cloak. His smooth golden hair flowed with his steps. In terms of looks alone, he could rival Su Yu.

Indeed, this person was clearly Gilderoy Lockhart. With his signature smile on his face, he strode towards Su Yu, laughing enthusiastically and exaggeratedly:

"Ha, look who I've found! Su Yu, one of only two handsome and exceptionally intelligent alchemists in the history of our Ravenclaw Academy! I've been looking for you for quite a while!"

"Hello, Gilderoy, it's nice to meet you! I have something to do, so I'll be going now!" Su Yu forced a smile as a greeting, and then immediately tried to slip away.

But Gilderoy Lockhart didn't give him a chance, hooking his arm around Su Yu's shoulder: "Su, don't do this. It's been so many years since we last met. I knew back in school that you would become the best alchemist in all of Britain."

"My judgment was right after all. Look at the changes that the Feather Magic Phone has brought to the magic world. It's truly amazing, a genius invention!"

"I bought your phone as soon as it was released, and now I have nearly 1000 followers."

Hearing Gilderoy Lockhart's words, Su Yu was also somewhat surprised. As expected of the top figure in the British magic world, his talent and sense of smell for hype were absolutely top-notch.

The Magic Phone has only been online for half a year, and this guy has already managed to create a Fetion group with nearly a thousand people. If the Magic version of Douyin is launched in the future, this guy will definitely become the number one live streamer.

However, Su Yu was in no mood to chat with this guy at the moment, and said directly, "Gidero, I really have something to do right now, how about we talk another day?"

Lockhart persisted: "That won't do. No matter what, you have to add my FlySignal first, otherwise it will be inconvenient for us to communicate."
