Hogwarts: I graduated before the system came

"Oh, do we really have to run in front of all these Muggles?"

"Hey, rather than running, I'm more looking forward to the opportunity to show off my spells in front of Muggles!"

"Should I report this to the Ministry first?"

Chapter 306 Shift Change

Lupin watched with satisfaction as, under the orderly organization of the two head boy and girl student union presidents, Percy and Penelope, the students quickly gathered into two columns of men and women.

Then he turned to look at the funny brothers George and Fred, and his smile became even brighter:

"I heard that you recently composed a song called 'The Hogwarts Song'. I'll give you a chance to lead the singing. Let's run and sing, spreading the pride and joy of Hogwarts on this road in the dim morning light."

"..."

"Percy, are you sure this isn't Professor Holmes in disguise?"

So, at Lupin's call, a burst of singing, initially sparse, gradually rose from the ranks, accompanied by their steady steps, from gentle to high, like a magical melody that crossed the boundary between reality and fantasy, echoing in every corner of Kennett River Port Road, awakening the sleeping city...

Of course, the main attraction was the sidelong glances from the Muggles passing by. The driver of a passing car even rolled down his window, laughed and shouted at them, "Come on! You should use magic to fly!"

The little guys in the team rolled their eyes.

Sirius Black, a man who had experienced countless hardships, at this moment, stood in the bustling and youthful crowd of Hogwarts, as if he had glimpsed his long-lost youth through the curtain of time.

He gazed at those lively and agile figures, their faces shining with innocence and fearlessness that had not been polished by the world. The curiosity and passion for exploring the unknown world rekindled in his heart like a burning flame.

Moon-faced Remus Lupin, who had experienced the vicissitudes of life, had a sly yet warm glint in his eyes, and a childish sense of humor...

At this moment, Sirius seemed to be in another world, and the memories that had been sealed by the years quietly opened up, like a ray of light breaking through the darkness at dawn.

He took a deep breath. The air was filled with the scent of youth, a unique fragrance woven from courage, dreams, and passion. It intoxicated him and awakened his deep desire for freedom, friendship, and adventure.

At this moment, he understood that no matter how time passes, the essence of youth will always remain as fresh as ever. It not only belongs to those faces full of hope, but can also illuminate every soul that yearns for light.

At that moment, Sirius felt as if he had merged into this endless torrent of youth, pursuing the excitement and infinite possibilities of life with those passionate young people.

"Gryffindor! We come from the wilderness, we crave strength, we are full of ideals, we are brave and fearless, we are righteous and courageous, we never give up, we are Gryffindor!"

With Sirius's sudden voice, the unity and harmony of "Hogwarts Song" was instantly broken.

Students from other colleges also shouted:

"Hufflepuff! We come from the forest, we have great love in our hearts, we are loyal to nature, we are upright and loyal, we are tough and honest, we are not afraid of hardships, we are Hufflepuff!"

"Ravenclaw! We come from the river, we are extremely intelligent, we think calmly, we study hard, we pursue the truth, we never give up, we are Ravenclaw."

The only harmonious thing is that there are no Slytherin students in this team...

Starting from the historic turning point in 1990, the British Muggle government, facing the dramatic changes in the global economic landscape and the urgent need to upgrade the domestic industrial structure, launched a deep and comprehensive industrial transformation revolution.

With their far-sighted strategic vision, they are guiding and promoting the gradual transformation of the overall economic ecology into a high-tech, high-value-added modern industrial system. In particular, they have high hopes for the two major fields of automobile and aircraft manufacturing, as well as electronic information, and have poured a lot of policy support and resource investment into them, striving to build them into new engines to lead national economic growth.

Precisely because of this background of decline, although the route of this trip does not pass through the highly industrialized cities in northern England, the route from London to Cardiff allows one to witness the changes that British Muggles have experienced from factory production.

There are both old factories that have witnessed the glorious years of British industry, which have been reborn after going through hardships and successfully achieved a gorgeous transformation from traditional industries to high-end manufacturing by introducing advanced production lines and technical talents; there are also new high-tech industrial bases that have sprung up like mushrooms after rain.

For the first time, the young wizards, including those who had left Muggle education, intuitively realized that the progress of Muggle technology had brought about earth-shaking changes in production and life.

The application of CNC technology, in particular, opened the eyes of the young wizards. For the first time, they realized that in some aspects, the technology and magic of Muggles were not too far apart.

Their shift change was like a sudden change in the weather, casting a subtle shadow over the hearts of the young wizards.

The originally lively and cheerful bus was now filled with a unique atmosphere of tension and anticipation due to this unexpected adjustment.

During these few days of close contact, the image of Sirius Black had undergone a profound transformation in their minds, from the man whose name was engraved on the Ministry of Magic's wanted poster, to a senior who was older but psychologically so close to them.

His weathered face seemed to be slowly returning to its youthful appearance. With witty and humorous language, he unfolded the war-torn era before everyone's eyes like a scroll.

Especially for Harry, although it was not the first time he had heard the story about his parents, every time he heard it, it seemed that Sirius would add some details he had never heard before. These stories were like a spell, awakening his longing for his parents.

The beloved guide Sirius was about to say goodbye. This familiar figure would soon fade out of their activities and be replaced by Professor Holmes.

What student would want to see their teacher's serious and earnest face during the holidays? Even if that teacher possesses exceptional wisdom and a keen eye for insight, and their classes are like a meticulously crafted detective story, full of suspense and surprise, with each class a thrilling intellectual adventure... (a student union president generously praised this).

But what they didn't expect was that Professor Holmes's reappearance was just an appetizer.

As the bus stopped, the students faced the most depressing moment of their study tour amidst their confused and incredulous gazes - the appearance of Professor Severus Snape.

Chapter 307 True Warrior

In front of a Muggle pharmaceutical factory, Professor Snape, dressed in his usual black robes, stood gloomy and indifferent. He said nothing, simply standing quietly by the side. His stern demeanor was like a piece of ice, instantly freezing the air around him.

The young wizards lowered their heads, wondering how much of their Potions homework they had left to do.

Only Harry tilted his head and looked at Professor Snape, but unfortunately, Professor Snape was not looking at him at this time, but at Douglas beside him.

Originally, Snape didn't want to come here at all, but after repeated persuasion and requests from Headmaster Dumbledore, in order to promote the advancement of potion-making technology in Hogwarts and the entire wizarding world, he, Severus Snape, decided to reluctantly agree to set foot in the Muggle pharmaceutical workshop to see and learn the unique features of the Muggle pharmaceutical technology.

Douglas greeted him warmly:

"Good morning, Professor. It's nice to see you here... ahem, aren't you going to say hello?"

The students around him twitched their lips when they heard Douglas' words. They suppressed their complicated emotions about seeing Professor Snape here and expressed their greetings one by one:

"Good morning, Professor Snape..."

Their voices were low and mechanical, and it was obvious that no one dared or was willing to say "Nice to see you here" against their will.

Professor Snape stood there, his black cloak swaying in the wind, his eyes as sharp as a hawk. He glanced coldly at the group of listless students, a sneer of contempt on his lips:

"Is this how you represent the image of Hogwarts? If I had known, I should have sent those well-trained and disciplined Slytherin students. In view of your performance, twenty points will be deducted from Gryffindor, and ten points from Hufflepuff and Ravenclaw..."

Harry stepped forward without hesitation, a challenging glint in his eyes:

"This isn't Hogwarts, you... I mean, Professor... you can't deduct points from us."

Although Harry's voice trembled slightly, his resolute attitude was evident.

Snape was not moved by this. On the contrary, a deeper sneer appeared on the corner of his mouth:

"Thank you for your reminder, Mr. Potter. I'll deduct points from you again when we get to Hogwarts. For talking back to the professor, Gryffindor will deduct another ten points..."

Douglas rolled his eyes. He didn't expect that he would have less worries after Sirius was transferred away, and there was also the reckless Harry.

He suppressed his helplessness and glanced at Harry. He first smiled and said to Snape:

"It's getting late, Professor. Let's go and see how the Muggles make their medicine."

Then he declared to all the students in an unquestionable tone:

"From now on, you must be extremely alert. Listen more, watch more, and feel more. If you have any questions or confusion, please raise your hands and ask. Everyone, follow me..."

Even though Harry was glared at, he realized his rashness and immediately restrained himself... He wondered if he should write a self-criticism in advance, just in case he needed it...

At this moment, the Muggle pharmaceutical factory they were about to visit had already been fully prepared.

The factory leaders received them personally and assigned a person with solid professional knowledge and rich experience to lead this group of young students on an in-depth visit and study.

As a long-established pharmaceutical company with a long history and a good reputation in the industry, they are no strangers to such activities. Every year, various schools apply to come and observe and learn, so as to absorb advanced pharmaceutical technology and management experience.

However, unlike usual, this time the school did not actively seek cooperation and exchanges with the company, but was directly notified by the government to receive a group of secondary school students from northern Scotland for a field visit and study.

This made them very curious, knowing that it was not only far from the north of Scotland, but also that both Glasgow and Manchester were the best choices for visiting.

Before officially entering the pharmaceutical workshop, the person in charge first led everyone into the locker room and took out a set of work clothes that met pharmaceutical hygiene standards for each person.

Watching the students put on their clean white work clothes, Douglas felt dazed, as if he had instantly traveled from the magical world to the rigorous and orderly world of Muggle pharmaceuticals...

However, even though the person in charge was talking endlessly about the importance and necessity of work clothes in the pharmaceutical workshop, Professor Snape seemed to be lost in thought. Although there was no hesitation in his eyes, his hesitation to change still exposed his inner thoughts.

but……

He looked at Professor Snape, who had an expressionless face and was holding his work clothes in his hand, but showed no intention of changing them.

The person in charge first introduced:

"When entering the workshop, you must first change into pharmaceutical work clothes, which are highly anti-static, corrosion-resistant, and high-temperature resistant..."

The person in charge took a look at Professor Snape's slicked hair, the corners of his mouth twitched slightly, and then explained:

"The reason for wearing this suit is, first, dandruff. The human body replaces a layer of skin every 28 days, and the dandruff shed daily poses a contamination hazard to the drugs being processed. Second, particulate pollutants from the mouth, nose, and ears. Third, pollution from cosmetics used by production workers. Fourth, the fabrics of the clothes you wear contain residues or ingredients that may contaminate or harm the drugs... Fifth, and most importantly, this hat can also prevent your hair from falling into the drugs..."

The person in charge looked at Professor Snape again...

The person in charge was an experienced veteran. He knew that some people might have doubts and resistance to this equipment, especially Mr. Snape, who was unkempt and exuded a strange smell.

He patiently and meticulously explained, "When entering our highly sophisticated and demanding pharmaceutical workshop, the first order of business is to change into this specially tailored work uniform. It not only possesses excellent antistatic properties, effectively preventing abnormal drug reactions caused by tiny electron transfer, but also boasts corrosion resistance, making it resistant to various chemical agents and ensuring worker safety. Most notably, it also boasts extremely high temperature resistance, protecting the wearer from potential exposure to high-temperature equipment or solutions..."

The young wizards listened to the string of high-level words, but also figured out the meaning from them. They all looked at Professor Snape. It seemed that their own Potions professor was not so rigorous in the process of making medicine.

Whether it was my own accident or not, everyone has been injured in Potions class. If I had a set like this... well, it would be best if it was a modified protective suit...

Neville touched his work clothes and thought that if he had this, even if he had an accident in every class, he wouldn't suffer so much...

Snape looked at the little wizards with a sneer. He could guess what these little guys were thinking. This was on the original version of the "Potions Classroom Rules" given by Douglas, but he had specifically removed it.

Only repeated lessons can make them remember that if they are not focused when refining potions, they will not only poison others, but are more likely to hurt themselves.

The person in charge's eyes lingered for a moment on Professor Snape's iconic, greasy black hair, and the corners of his mouth twitched imperceptibly, as if he was suppressing a subtle emotion. He straightened his body and began to explain in detail in an extremely professional tone:

"Mr. Snape, you may not have thought about this deeply, but every tiny detail in our pharmaceutical environment is crucial.

There are multiple reasons why all personnel are required to wear this special clean suit in the laboratory:

First of all, human skin is a wonderful and constantly metabolizing system, which completes a comprehensive renewal and replacement every 28 days on average. The amount of dandruff that falls off from our body surface every day is unimaginable.

These seemingly insignificant pieces of skin flakes can become a potential threat of contamination for pharmaceuticals that are precision-processed and strictly sterile.

Secondly, we cannot ignore the various particulate pollutants that escape from the three major natural excretion channels of the human body - the mouth, nose and ears. The droplets when speaking, the dust produced by breathing, and the earwax that is inadvertently released may quietly mix into the precious medicines and destroy their purity and efficacy.

Furthermore, there are many other factors, such as the shedding of clothing fibers, the impact of body odor on drug ingredients, etc. These are all taken into consideration when we formulate strict dress code.

However, the most critical point, and the one I specifically mentioned about this hat, is that it can effectively prevent hair, a common pollutant in daily life, from falling into the drug manufacturing process.

After all, even a tiny strand of hair can cause irreversible quality damage to advanced pharmaceuticals."

When the person in charge said this, his eyes were once again fixed on Professor Snape's shiny and slightly messy hair. The meaning of his expression was self-evident, as if he was suggesting that Mr. Snape should pay more attention to the hygiene standards of the laboratory.

"Sigh~"

The young wizards gasped, and the temperature in the room immediately rose by two degrees.

What a warrior!

Chapter 308 Professional

Douglas's mind was racing with thoughts of the possible punishment Professor Snape might take: was he planning to use the Oblivion Charm to erase the unpleasant memory, or cast a Confusion Charm to make the entire factory think he was wearing work clothes?

A cold silence suddenly fell in the entire classroom. Professor Snape's eyes were like sharp eagle eyes, and he glanced coldly at the frightened little wizards around him. Then, he raised the white work clothes in his hand, and walked straight to the locker room without a word.

Douglas looked at this scene, a complex feeling of pity flashed in his eyes as he looked at the little wizards.

Then, his eyes followed Professor Snape's aloof and resolute back, and he couldn't help but wonder in his heart: Could it be that this professor, who is usually strict and harsh and never compromises easily, has really changed his temperament?

It was originally thought that Professor Snape would at least leave in anger, leaving behind a greasy head, even if he would not inflict direct harm on the Muggle leader who dared to speak rudely to him. However, at this moment, Snape's choice exceeded everyone's expectations.

The young wizards gasped again, as if they could hear the sharp sound of air flow echoing in the classroom. They looked at each other in confusion.

At this moment, some people even began to doubt whether Professor Snape in front of them was a substitute found by Professor Holmes. After all, this sudden silence was in sharp contrast to Professor Snape's usual hot temper.

Harry's face darkened in an instant, his eyes flashing with complicated thoughts.

He keenly caught the subtle change in Professor Snape's expression when he left just now. It was an expression mixed with contempt, dissatisfaction and anger. This scene instantly made his memory go back to his first year.

At that time, Snape, just because Harry caught a glimpse of Harry's limping figure, did not expect that this slight emotional fluctuation was accurately captured by Snape, and he took this opportunity to ruthlessly deduct points from Gryffindor House and even punished Harry by banning him from entering the library to borrow books...

At this moment, when Harry saw Snape being accused of having "greasy hair" in front of a Muggle, and the other party looked at them, he couldn't help but feel a chill in his heart.

He worriedly wondered whether Snape's sect would once again seize upon this seemingly insignificant matter and punish them harshly under some pretext when they returned to Hogwarts. The most important thing was that he was the one leading the team in this activity.

He subconsciously turned his gaze to Douglas beside him, but what he saw was Douglas giving him a helpless smile, and he could even sense a sense of mockery from it, as if he was watching a play. This undoubtedly added a bit of heaviness to Harry's already uneasy heart.

Harry's heart sank like a stone into the depths of a valley, and he felt that the coming storm might be more violent than he had imagined...

The Muggle person in charge, who knew nothing about his own experience, was lingering on the edge of death without realizing it, and was now witnessing the students' extremely subtle reactions to this sudden incident.

His insightful eyes, the moment he caught the children's complex emotions, involuntarily turned to Snape. Thinking of the teacher's previous performance and situation, ripples could not help but appear in his heart.

He speculated, without any ill intention, that this teacher's interpersonal relationships at Hogwarts Middle School had probably hit rock bottom. Tsk, tsk, thinking back to the cold glances he'd received every time he'd passed by, the unattended classes, even the afternoon tea breaks he'd deliberately avoided... The students' alienation and indifference undoubtedly painted a vivid picture of this teacher's isolation and helplessness...

He also imagined in disbelief what kind of situation was hidden at Hogwarts Middle School in the teaching environment created by such a controversial and unpopular teacher.
