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

Su Yu thought to himself that Chen Ying's cosplay was getting more and more outrageous, but he had a faint wicked smile on his face and said, "Little reindeer, tonight I, Santa Claus, will ride you to deliver gifts to children all over the world!"

……

Su Yu stayed in the United States until the morning of the 27th before returning to the United Kingdom. Upon his return, he immediately went to see Tonks. This was not because he was a jerk, but because Tonks had already arranged a meeting for him with Kingsley.

During lunch break, the three sat down in a restaurant near the Department of Magic. Kingsley, still showing Su Yu great respect, took the initiative to ask, "Professor Su, I heard from Tonks that you wanted to see me?"

Su Yu nodded, took out Zhang Qiu's drawing from the bag, and handed it over, saying, "Does Captain Kingsley remember this person?"

Upon seeing Dracula's face, Kingsley's expression immediately turned serious. He said, "Of course I remember. This is the guy who kidnapped Jinx and later injured several of our Aurors."

Su Yu nodded: "That's right, his name is Dracula, a vampire count. His hometown is in northern Scotland. He was sealed away for five hundred years by a descendant of Slytherin. I guess he broke free of the seal not long before he captured Tonks."

“I have something he really wants. To get it, this guy kidnapped the mother of a Hogwarts student and planted a curse on the student and her father!”

Upon hearing the curse, Tonks slammed his fist on the table in anger: "A curse again! That bastard used a curse last time to prevent me from using magic!"

Su Yu comforted Tonks, then turned to Kingsley: "I came here today hoping to ask Captain Kingsley to help me find this guy's hideout. I need to rescue my student's mother."

"Here is the student's information, including his family background. Captain Kingsley, you can take a look."

Kingsley took Zhang Qiu's file, reviewed it carefully, and then assured Su Yu, "Don't worry, Professor Su, I will give this the highest priority and rescue this mother from the vampires as soon as possible."

Su Yu was not optimistic about this. He knew Dracula's strength. His magic power, recovery power, strength, and speed were all at least LV9 or above. Even if more than a dozen Aurors attacked him, it might not be effective.

However, to save Kingsley's face, Su Yu still said tactfully, "You misunderstood. What I meant was, if you find out his whereabouts, please notify me immediately. After all, our primary goal is to rescue the hostage."

“If we act rashly, I’m worried that this vampire will fight to the death and kill the student’s mother.”

Kingsley thought about it and realized that Su Yu's words made sense, so he readily agreed.

When Su Yu returned to Hogwarts Castle, it was already close to evening. He didn't go back to his office first, but went to Snape's place and asked, "How are the preparations going?"

Snape glanced at him, but didn't speak immediately. He first took out ten bottles of green potions from his pocket and said, "These are antidotes. After drinking them, you will not be afraid of any toxins for five minutes."

Then he took out two bottles of red potions and said, "These two are burst potions that can temporarily increase your maximum magic power without any side effects!"

Finally, Snape took out the two pairs of glasses that Su Yu had given him earlier and said, "I coated them with a magic potion, doubling their magic resistance, hardness, and corrosion resistance."

Seeing that Snape was so well-prepared, Su Yu extended his fist: "In that case, our operation will take place tomorrow, codename: Snake Slayer! The Snake and Hawk Duo..."

"Victory is assured!"

Chapter 124 Slaying the Serpent (Part 1)

Operation Snake Slaying officially began. Early in the morning, Su Yu and Snape arrived at the entrance of the girls' washroom on the second floor of Hogwarts.

Snape looked at the girls' restroom in front of him and subconsciously glanced around. After all, he was the head of Slytherin House and the most handsome Potions professor at Hogwarts, so he still had some image to maintain.

If someone sees him trying to enter the girls' restroom, how will he ever be able to keep a straight face with the students again, and how will he ever be able to scare those disobedient little wizards?

"Are you sure this is the place?" Snape's trust in Su Yu had plummeted to rock bottom; he felt like this guy was trying to scam him.

"We'll find out once we go in!" Su Yu didn't have as many internal monologues as Snape, and stepped inside.

Snape had wanted to help Su Yu, but he was too late. It would have been even more awkward for him to stand at the entrance of the girls' restroom, so he quickly followed after him.

As soon as Snape entered the bathroom, he heard a scream: "Ah! Pervert! You pervert! It's you again! You peeping tom!"

Snape was startled. Were there girls inside? If he were accused of peeping at female students using the toilet, his reputation would be ruined.

Fortunately, looking in the direction of the sound, Su Yu saw that the screaming person was Myrtle crying. He pulled out his wand, pointed it at Myrtle, and threatened, "Stop making a fuss, or I'll cast a spell on you to freeze you!"

Myrtle was terrified and quickly covered her mouth with her hand, making muffled noises, but her eyes were still full of fear.

"What did you do to Myrtle that made her so afraid of you?" Snape stepped forward and stood next to Su Yu in front of the sink.

"This is none of your business," Su Yu said irritably. He was also curious as to why Myrtle harbored such resentment towards him.

Snape frowned and continued, "What are you doing standing here? Want to wash your hands?"

Su Yu ignored him and quickly found the snake-shaped metal pattern, then took out a small cylindrical speaker from the seamless stretch bag.

He held the speaker in his hand, pressed the top round button, and said, "I, the great Salazar Slytherin heir, hereby command the Chamber of Secrets to open!"

After speaking, Su Yu pressed the triangular button on the speaker, and a loud hissing sound came out of the speaker the next moment.

Snape was stunned and asked incredulously, "Is that Parsleyan?"

"Hmm!" Su Yu proudly raised his chin.

Seeing that smug expression, Snape decisively chose to shut up. In his experience, ignoring Su Yu when he was showing off was the best option.

The next moment, the circular washbasin in front suddenly began to shake, the stone platform in the middle slowly rose up, and the surrounding washbasins spread outwards, revealing a passage in the middle.

"There really is a secret room!" Snape's words were tinged with surprise and excitement.

The two then walked into the passage together. The passage was very long and could be felt as if it was spiraling downwards. They walked for an unknown amount of time before finally arriving at a stone door.

Su Yu repeated the operation he had just performed. Under the command of the snake-like voice, the stone door gradually opened, revealing a spacious hall behind it.

In the center of the hall was a stone passageway, flanked by two pools of water. At the very front stood a colossal statue of Slytherin, his hair and beard flying wildly, his eyes and mouth hollow, as if he were roaring angrily.

Just as Snape was marveling at the spaciousness of the secret chamber, the hissing sound rang out again, but this time it wasn't coming from Su Yu's speaker.

Su Yu shouted, "Put on your glasses!"

Then he put on the glasses himself, took the wand, and pressed a square button on the speaker.

Snape reacted quickly; as soon as Su Yu finished shouting, he immediately put on his glasses, and at the same time heard the voice coming from the speaker:

"Who... has... trespassed... into my territory again? I will kill you... kill you..."

"Is that the voice of a basilisk?"

"if not?"

As the two were talking, a huge blue head appeared in their pitch-black vision after they put on their glasses. Although the outline of the thermal image was not very clear, it was enough to tell that it was a snake's head.

The basilisk emerged from Slytherin's eyes, its gaze fixed on the two people before it. This was the second wave of uninvited guests to intrude recently.

But in Su Yu and Snape's eyes, this basilisk was rather strange; its entire body was ice blue, indicating that its surface temperature was very low.

The eyes, nose, and mouth are red, indicating that these three areas are relatively warm. However, only one of the snake's two eyes is red, while the other is black, appearing as if it were an empty hole.

As the two had suspected, the basilisk did not look particularly well. One of its eyes appeared to have been gouged out, leaving a huge, unhealed wound.

The basilisk was also reminiscing. He had been asleep in this secret chamber for nearly a thousand years, until he was awakened once fifty years ago. Unfortunately, not long after he woke up, his new master disappeared again.

The basilisk had to fall back into slumber until recently, when a girl came along with the scent of her former owner. She woke it up and took it for a walk.

Later, another girl arrived, who also possessed the aura of her master. The basilisk didn't know why so many people had the aura of their masters, but he was happy to be able to go out and play and eat.

Unexpectedly, on the third occasion, the girl brought an uninvited guest—a powerful vampire. She not only defeated it head-on but also gouged out one of its eyes and drank a lot of its blood.

The basilisk was furious, but the man left quickly after succeeding, leaving him no chance for revenge. The more the basilisk thought about it, the angrier it became.

Looking at the two people in front of him, who seemed to be similar to the vampire, he was sure they were his accomplices: I, the Basilisk, will eat you two up today as interest for gouging out my eyes.

Then the basilisk exerted force with its tail, and the entire snake flew out like an arrow, heading straight for Su Yu and Snape!

"They're here, get ready for battle!" Su Yu reminded them.

In Su Yu's vision, the speed that this snake monster suddenly burst forth with, although not as fast as Coal Ball, was still very fast.

Moreover, when he locked eyes with the basilisk, even with the protection of his glasses, he could still feel a dark and eerie magic eroding his spirit and trying to penetrate his body.

Some legends say that the sound of a rooster crowing can kill a snake monster, but according to the information Su Yu found...

The rooster that could kill the basilisk was no ordinary rooster, but the very rooster that hatched the basilisk. Obviously, that rooster had died hundreds of years ago, so now the basilisk only had one weakness left: its eyes!

Chapter 125 Slaying the Serpent (Part 2)

Snape waved his wand and fired a thunderous blast at the basilisk's bulbous eyes. The red spell arced through the air and struck precisely.

As Snape attacked, Su Yu coordinated perfectly with him to defend. Su Yu waved his wand and chanted the spell: "Obstacles!"

Su Yu had used this spell before when dealing with the giant, but the effect was not good. Under the giant's terrifying power, several air walls were torn apart instantly, and it had almost no effect.

The basilisk's power was no weaker than the giant's, so when Su Yu cast this spell, he also used the Transfiguration technique to transform these air walls into something similar to aerogel.

With a bang, the high-speed basilisk crashed into the aerogel wall, just like a high-speed iron ball hitting a non-Newtonian fluid.

The first layer of aerogel didn't last long and quickly broke, but the basilisk's speed was also reduced. When it tried to penetrate the second layer of aerogel, it seemed to be stuck in a quagmire and couldn't move forward an inch.

The basilisk was brought under control, and Snape's Explosion Charm arrived just in time. With a loud bang, the basilisk was blasted back several meters, and Su Yu's Barrier Charm was also shattered into pieces.

As the smoke cleared, the basilisk shook its massive head. Just moments before the explosion, it had cleverly closed its eyelids. Although its eyelids were twitching a little, it wasn't seriously injured.

Ever since that damned vampire gouged out one of its eyes, the basilisk has clearly become more protective of its remaining eye. These two are indeed in cahoots with that vampire; they even want to gouge out its eye too.

"Snape, you defend, let me try the offense!" Su Yu said.

Snape had some doubts. Offense had never been Su Yu's strong suit, and even though he had made great progress in the past year, Snape still believed that he was better in this aspect.

"Are you sure you can do it?" Snape asked skeptically.

"Let me give it a try. I have some new gadgets that might be able to deal with this big guy!" Su Yu reached into his seamless extension bag and pulled out a handful of small iron balls.

Snape assumed Su Yu had some new alchemical artifact, so he said, "Alright, I'll help you hold it off."

Snape was right, but also wrong. These small iron balls were indeed Su Yu's latest alchemical items, but they were not for combat.

Their only characteristic is that they are heavy and dense, making them very suitable as the base material for transformation techniques.

Su Yu tossed the small balls towards the basilisk, waved his wand, and uttered a Chinese phrase: "Scatter beans to create soldiers!"

Following the previous "Ten Thousand Swords Return to One" technique, Su Yu has developed another traditional Chinese magic. Several small iron balls in the air kept changing shape.

Upon landing, it had fully unfolded, becoming a standing, automated turret covered in magical runes.

Rat-a-tat-tat... The automatic turrets don't have a high rate of fire, only one shot per second, but the bullets they fire are 25mm in caliber, which is enough for anti-aircraft defense in the Muggle world.

In addition to their large caliber, these bullets are also coated with icy energy, which causes each bullet to leave a trail of mist in the air, even at extremely high speeds.

With a crackling sound, the icy bullets struck the basilisk, causing it to roar in pain. However, Su Yu's desired effect was not achieved, as the bullets shattered and bounced back upon impact with the basilisk's scales.

Despite its loud roar, the basilisk was actually unharmed. After its roar, it even swung its tail and slammed it into the nearby automatic turret.

Seeing that these cannons seemed useful, Snape naturally wouldn't let the basilisk destroy them easily. He also used his own obstacle-filled formation to block the basilisk's whipping.

The basilisk turned to look at Snape, and seeing that it could not break through the blockade, it simply opened its mouth and sprayed two thick streams of venom from its fangs, shooting straight at Snape.

Snape reacted swiftly, his armor protecting him from the basilisk's venom. However, the venom evaporated rapidly on the shield he erected, turning into poisonous gas.
