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

"Bastards, you bastards, you've gone too far! I'll kill you all!" Dracula was so frustrated that his voice echoed in the room, but he had already turned into a pool of blood and re-coagulated ten meters away.

Chapter 156 End of the School Year (Part 1)

Dracula's physical form reappeared, returning to human form. Three minutes had passed since he arrived at Hogwarts, and he had not only failed to retrieve the remains of the Pounder Pot, but had also lost the key to the escape portal.

What upset Dracula even more was that he had discovered that this was not Su Yu's office at all, but an alternate dimension, and it was impossible for him to fly away through the window.

Staring at Su Yu, Dracula felt a surge of resentment. Ever since he escaped his predicament and encountered this guy, nothing had gone smoothly. Since that was the case, he had no choice but to use his last resort.

Dracula took out the bottle of tainted blood again and gulped it down. Su Yu could clearly see that the guy's face began to turn red and swell up. Was he about to explode?

The three of them were so frightened that they immediately retreated and summoned their guardian spirits. If Dracula really chose to self-destruct, his filthy blood would splatter everywhere, and the three of them would inevitably be injured.

An explosion was of course impossible. Dracula opened his mouth again, spitting out a mouthful of blood. However, his target was not Su Yu and the others, but the bouncy pot that had fallen to the side.

The blood was very viscous; when it was sprayed onto the remains of the bouncy pot, it resembled a lump of gel, sticking to it and making a sizzling, corrosive sound.

"Su Yu, don't be so smug. You've won this time, but I'll be back!" Dracula roared, pulling out a short knife and stabbing it directly into his heart.

With a "poof," blood gushed out. Dracula drew a line in the air, and the blood, drawn by his magic, formed a magic circle made of blood in front of him.

Su Yu used the scanning tool on his glasses to quickly examine it and found that it was a spatial magic circle diagram: "He's trying to run, stop him!"

After saying that, Su Yu commanded his guardian raven to rush out and try to shatter Dracula's magic circle.

Snape and Flitwick simultaneously cast Fiendfyre and Explosion, and the next moment, the magic circle made of blood twisted and bent, enveloping Dracula within it.

Before the three magic spells could strike the blood magic circle, the magic circle, carrying Dracula, vanished into thin air.

All three looked extremely grim. Inside Hogwarts Castle, the two Headmasters and a Professor had joined forces to let a vampire escape—this was an utter disgrace.

"Damn it, he got away!" Snape said bitterly.

Su Yu didn't say anything, but quickly walked to the remains of the jumping pot. He looked at the blood, which was almost pure black, and saw that it had corroded a dent on the surface of the jumping pot.

Su Yu frowned, took out a bottle, and tried to use his wand to control the black blood to enter the bottle. However, just like the Bloodstained Curse from before, the magic power lost its effect when it touched the blood, and there was even a risk of it backfiring on his mind.

Opening the seamless stretching bag, Su Yu took out several scrapers, some made of stone, some of metal, and some of bone, and tried them one by one. As soon as these things touched the lump of black blood, they were immediately corroded.

Moreover, the black blood was extremely viscous. Su Yu scraped it hard several times, even damaging the scraper, but he still couldn't scrape the black blood off.

"Take this to me, I'll see if I can concoct a corresponding cleaning solution," Snape said as he approached Su Yu.

The black blood didn't cover a large area of ​​the wreckage of the bouncy pot, so Su Yu felt comfortable handing it over to Snape. However, he still had some doubts:

"Dracula risked entering Hogwarts for the remains of the Pouncing Pot, but before he left, he spat this strange black blood on it. What do you think was his reason for doing that?"

Snape shook his head: "How would I know? I'm not a vampire."

Professor Flitwick, standing to the side, speculated, "Sue, according to what you said before, the last time he came to Hogwarts, he took the basilisk's eyes and blood to strengthen himself."

"Then this time, he must be here to take the remains of the Jumping Pot for the same purpose!"

Su Yu felt as if he had been struck by lightning. Yes, this guy must still be trying to increase his strength. He looked at the remains of the Jumping Pot again and thought of Dracula's scales, which were similar to those of the Basilisk.

A bad feeling crept into my heart. What if the next time I saw Dracula, he would have the same skin as the Jumping Pot? If that were the case, it would be terrifying.

After collecting the remains of the bouncy pot, the three walked out of the Room of Requirement, just as Professor McGonagall and Dumbledore arrived at the door.

"How are you, Sue?" Professor McGonagall asked with concern.

Su Yu shook his head: "That guy got away. He pierced his own heart and created a blood magic circle, which enveloped him and allowed him to travel through space."

Dumbledore wasn't too surprised and said, "Vampires possess many bloodline secrets that even I don't know about. You've done a great job for forcing him to pierce his own heart. I believe this guy won't be able to operate in the wizarding world for a long time."

"Did Qiu see her mother?" Su Yu asked.

Dumbledore shook his head: "Not yet. Fawkes and I came back first. Cho's mother will be sent to Hogwarts by Kingsley later. Madam Pomfrey and I will conduct a more thorough examination on her."

After chatting casually for a few more minutes, Su Yu, along with Dumbledore and the remains of the bouncy pot, went to Snape's office.

When Dumbledore saw the black blood, he was also taken aback. Then he pointed his wand at the black blood, and countless white threads shot out from the tip of the wand.

The moment the silk thread touched the black blood, Su Yu saw that the black blood was flowing upwards, trying to devour Dumbledore's wand.

But Dumbledore was, after all, the most powerful white wizard of his time, and his immense magical power quickly suppressed the black blood back.

Putting away his wand, Dumbledore said, "It's terrible dark magic. It devours everything around it and uses it for its own purposes. Even I can't remove it with magic."

“I sense a powerful soul force within this thing. Perhaps we could try using the juice of the Star Spirit Flower and the Brain-Eating Worm,” Snape said.

"A good idea!"

……

About three hours later, at Hogwarts Hospital, Cho Zhang met her mother, and Peter Zhang was also brought there. The three of them embraced and wept upon seeing each other.

Ten minutes later, Peter Zhang stood up, bowed deeply to Su Yu, and said, "Professor Su, thank you for your help. If it weren't for you, my family would have been doomed!"

"This isn't just my achievement; everyone here participated in the rescue. But you'd better move after this, because Dracula isn't dead..." Su Yu said regretfully.

“Okay, Professor Su, we plan to move to the United States, and Qiu will transfer to Ifamoni,” Peter Zhang said.

Hearing this, Su Yu was somewhat surprised and couldn't help but wonder, if Cho Zhang went to Ilfamori, who would be Harry Potter's first girlfriend?

Before he could think any further, the system's voice rang in his mind: Ding, congratulations to the host for completing the main quest, the principal's request, and obtaining 1 free skill point.

Chapter 157 End of the School Year

Su Yu was overjoyed. He had completed another main quest. Although Dracula's problem was not perfectly resolved, for the time being, he no longer needed to worry about him having any impact on Hogwarts.

I opened the system panel and saw that I had three free skill points again. Without hesitation, I should just focus on increasing my magic power.

Back in his dorm, Su Yu immediately started allocating skill points. Of all the skills, allocating points to magic was the most painful. When allocating points to other skills, what entered his body was experience and memory, which he could digest slowly.

But magic points are different; each increase doubles the magic power. That newly generated, enormous magic power, like the Obscurial, rampages through his body, tearing apart and repairing every cell.

Although this would also greatly increase Su Yu's physical resilience and cell activity, the excruciating pain that penetrated to the bone made Su Yu feel like he was dying every time!

The entire process of adding points lasted fifteen minutes. After it was over, Su Yu's sweat had soaked the sheets. Feeling the surging magic, Su Yu felt that if he were given another chance, he might actually be able to keep Dracula.

Time flies, and another school year is coming to an end. For the next month or so, Su Yu devoted all her energy to teaching and adding and deducting points.

So far, his Academy achievements are all at Level 2. To reach Level 3, he needs to either gain or lose 1,000 Academy points.

Fortunately, Dumbledore agreed to give Ravenclaw the House Cup this year, but Dumbledore wouldn't directly participate in the specific bonus points; Su Yu would still need to fight for them himself.

As a result, the students gradually discovered that Su Yu had become a ruthless point-deduction and point-addition machine. Students from all four colleges would have points deducted if they made any mistakes in class.

Sometimes he gets one or two points, and sometimes he can even get ten or twenty points, making everyone cautious when attending Su Yu's class.

In the school corridor, Hermione, carrying a stack of books, said to Harry and Ron beside her, "Have you noticed? Professor Sue has been particularly fond of deducting points from everyone lately."

“Of course I noticed! Professor Su has already deducted 15 points from me this week. He didn’t deduct this many points from me all last year!” Ron immediately agreed.

"That's your own fault! Who told you to be so engrossed in wizard chess and not do your homework!" Hermione showed absolutely no sympathy for Ron.

"Come on, I'm trying to get Diamond rank. This season is almost over, and if I don't try now, I'll miss my chance. Besides, Harry lost 10 points!" Ron defended himself.

Harry nodded: "That's right, I feel it's because Professor Dumbledore forced Professor Sue to take the Defense Against the Dark Arts class, which made Professor Sue's mood worse."

As they talked, the trio arrived at the Potions classroom, placed their books on the table, and seeing that Snape hadn't arrived yet, Ron continued:

"But have you noticed that although Professor Su Yu has become stricter in deducting points from everyone, he's been giving Ravenclaw a lot more points!"

Harry nodded: "I've discovered that Ravenclaw's House Points have reached 476 so far, which is more than 30 points higher than ours. If nothing unexpected happens, Ravenclaw will probably win the House Cup."

Hermione retorted, "Why don't you think about your own problems? The Ravenclaws read three times as much as you do every day, and what about you?"

Harry and Ron exchanged a helpless glance. They knew they couldn't compete with Hermione when it came to academics, but they were not convinced.

Ron said, "I think it's because Professor Sue herself is from Ravenclaw that she's biased towards Ravenclaw!"

Harry agreed: "That's right, although we can't beat Ravenclaw, we're still 10 points ahead of Slytherin!"

*Slap! Slap!* Two large hands landed on Harry and Ron's heads respectively. Snape's gloomy face emerged from between the two, and he shouted:

"Harry Potter and Ron Weasley, for privately slandering the Professor, I will deduct five points from each of you!"

Cheers erupted from Slytherin's side, while Gryffindor fell silent. Snape's voice deepened again as he whispered, "Now, Gryffindor and Slytherin are evenly matched!"

Hermione was somewhat unconvinced and raised her hand, saying, "Professor Snape, we did not slander Professor Sue; we were just having a normal discussion."

Snape, completely ignoring Hermione, pointed at her and said, "Miss Hermione Granger, speaking out of turn, two points deducted from Gryffindor!"

In fact, Snape had also noticed his house grades plummeting these past few days, and he had been working very hard in Potions class to earn more points for his young wizarding career.

But every time he checked after class, his score was either unchanged or even lowered by a few points. After investigating, Snape discovered that Su Yu was behind it all.

Unfortunately, by the time he realized the problem, Ravenclaw's points were already more than forty points ahead of Slytherin's.

Snape had also spoken to Su Yu, but Su Yu only had one thing to say to him: "I add or deduct points based on my own ability, what's it to you!"

So, Snape, having been humiliated, decided that from now on, he would deduct points from his Potions classes even more drastically than Su Yu.

As soon as Snape entered the classroom, he saw Harry Potter and Ron Weasley whispering to each other.

Upon closer listening, I discovered they were saying that Gryffindor was ten points higher than Slytherin. So what's there to hesitate about? Let's start with you!

In this lesson, Gryffindor lost a total of 15 points, while Slytherin gained 20 points, allowing Slytherin to overtake Gryffindor by 25 points.

Professor McGonagall was completely stunned as soon as get out of class ended. Before class, her college was ranked second, but after one class, it had been pushed down to third. How did this happen?

Gradually, apart from Professor Flitwick, the other three deans were all drawn in by Su Yu, and the college rankings became quite exciting, with scores fluctuating by as much as 50 points in a single day.

Finally, an academic year came to an end. Thanks to Su Yu's unremitting efforts, the students who took the Common Wizarding Levels (OWLs) and the Ultimate Wizarding Levels (NEWTs) all did quite well in the Defense Against the Dark Arts course.

But this year, apart from Ravenclaw, almost no students from other houses came to thank Su Yu, because they were afraid that if they said something wrong, the professor would deduct points from their scores.

At the graduation ceremony, Dumbledore addressed the entire school, saying, "Now I congratulate Ravenclaw on winning this year's Hogwarts Cup!"

Amidst the cheers of countless Ravenclaw students, Su Yu's system also rang: Ding! Congratulations, host! Thanks to your tireless efforts, your Ravenclaw school has won the final House Cup, and you have gained 1 free skill point.

It has been detected that your contribution to the annual score of this Academy Cup exceeds 50%. The system will award you an extra 1 free skill point. Keep up the good work!

Chapter 158 Feiyu’s new product

What a surprise! What a huge surprise! Su Yu had long guessed that he would receive a reward when Ravenclaw won the College Cup, but he never expected the reward to be so generous.

These are two free skill points. Looking at the progress of his academy achievements, Su Yu is certain that next semester, he will be able to raise his magic power to level 10!

After finishing their last lunch, Su Yu and the professors escorted the young wizards to Hogwarts. Dumbledore came to Su Yu's side:
