Section 1

At the crowded train station, Sauron appeared quietly in the bustling crowd. The dense raindrops fell on his black robe and slid silently, turning into mud under his feet. The air was filled with the unique smell of machinery. On the rails beside him, the train heading to Hogwarts was already in place. The crimson steam locomotive dragged the long passenger compartment, waiting for the travelers who were about to travel far.

The parents were saying goodbye to the children who were about to leave. The classmates who had not seen each other for a long time greeted each other. The owls were squeaking. Many children were looking around, waiting for the first time in their lives to leave home with excitement or anxiety. However, all this had nothing to do with Sauron. He passed through the thick smoke emitted by the locomotive alone, not caring about others, and no one cared about them. Occasionally, someone saw his eyes inadvertently, and hurriedly moved away and avoided the side with fear.

Sauron walked on the train, walked straight toward the front of the train, found an uninhabited compartment and sat in. The students in the aisle were walking back and forth. During this period, several Hufflepach broke in and hurried out after seeing Sauron. Sauron sat in his seat, looking at the lonely planet written by the Wheeler couple in his hand, like an ordinary traveler, was spending the time before the train set off.

The door of the compartment was pushed open again, and someone sat opposite Sauron, carrying a faint rose scent.

"Good perfume." Sauron looked at the book in his hand and said without raising his head, "It seems that you are in a good mood, Isabella."

"For your blessing, the holiday is good." Isabella leaned against her seat and looked at the book in Sauron's hand with interest. "Why, are you starting to be interested in Muggles?"

"In fact, I know more about Muggles than you think." Sauron put the book down and looked at the girl opposite him, noting the surprise that flashed across her face. He smiled and said, "What, are you surprised?"

Soren knew why she was surprised - of course not because he was looking at the travel guide, but because his eyes, the golden sword eyes were deep and sharp, without any concealment.

"You plan to keep doing this?"

Isabella asked with an eyebrow raised, of course she would not think that Sauron was targeting her because it had no meaning and did not conform to his usual style. The only explanation was that he did not intend to continue to hide his identity as a demigod.

"Why not?" Sauron said indifferently. He turned his head and looked out the window. The crowd seemed to be much less sparse than before. As the departure time approached, more and more people had boarded the train.

"Okay, you're the boss." Isabella shrugged, took out a book from her bag, and hid in the chair and started reading.

Time passed by minute by minute, and when the whistle sounded sharply before the train left, Draco also walked into the compartment, as well as Crab, Gal and Pansy. Soon, the train left the city and entered the field, heading north, and the rain became heavier and harder. The sky was pitch black and the car windows were covered with water, so lanterns were lit in broad daylight.

Seeing Soren's eyes, Draco and his men couldn't help but be stunned for a while, but soon they stopped caring. Except for Draco, the other three people more or less avoided Soren's sight. After a simple greeting, the few people started chatting and passed the time on the train.

"The things at the World Cup made Fudge furious." Draco looked at the Daily Prophet in his hand and smacked his lips. "The media chased the Ministry of Magic like a dog, and now Americans and Germans are getting involved again..."

"It's not surprising. In the remaining half a year, the Joint Meeting of Ministers of the Wizards Alliance will be held. More than 20 important issues will be decided, at least half of which are about the formulation of new magical technical standards, which involves terrible economic benefits. The politicians and the interest groups behind them may not be good-looking."

Pansy said, rolling her hair with her fingers. She looked at Draco with a meaningful smile on her face. "I heard that Uncle Malfoy is keen on charity recently, and he also donated a large sum of money to Saint Mungo that would be repaired in another hospital..."

"Please, Pansy, your words sound like a cynical old peddler." Draco glanced at Pansy and said disrespectfully, "If I remember correctly, don't your family sponsor a large sum of money to host the Triple Championship?"

Pansy snorted, turned his head and ignored Draco. At this time, Isabella put down the book and looked at Sauron, "When it comes to the Triumph, will you participate in it?"

"Forget it, I won't join in the fun." Sauron shook his head. "I bet that if I attend, letters of protest would be filled with Slytherin's lounge."

Everyone laughed, and Draco continued, "That's good, at least Slytherin can win the championship in the Final Three. I have a distant cousin at Demstrong. It is said that their school has been organizing students to train during the holidays to prepare for the Final Three."

"It's not surprising, think about who their principal is - Igor Kakarov, that old fox."

Isabella sneered, contempt and disdain were beyond words, and obviously had a bad impression of the principal of Demstrong.

"Well, I actually want to go to Demstrong to see it." Draco said with some regret. "It is said that their attitude towards black magic is much more open to Hogwarts. They are really teaching black magic, not like Hogwarts' funny black magic defense."

"You say that, Dean Snape will be sad." Isabella quipped, "he has always wanted to teach this class."

"Haha, I'm afraid there's something that makes my godfather even more sad." Draco said with a smile, "I heard from my father that Dean Snape is going to be disappointed again this year. But you can't guess who will be the teacher of the Dark Magic Defense this year."

"Who knows, it's not a vampire, right?" Pansy said, "but to be honest, that werewolf was quite interesting in class."

"It's Mad-eyed Moody!" Draco said in a low voice, "I didn't expect that Dumbledore would actually call him as a teacher."

Several people didn't make a sound for a while. Draco's eyes swept across several people and found that except for Soren's face, there was no emotion on his face, the others showed more or less surprised expressions. It was obvious that they all knew about crazy eyes, and they didn't expect to deal with him at Hogwarts this year.

"That old madman, his attitude towards Slytherin is not considered friendly." Pansy said with a frown.

"In fact, he was not friendly to most people," said Isabella. "That guy was a paranoid lunatic, but he was really powerful. Until he retired a few years ago, half of the people in the Azka class were sent in."

"What do you think about this?" Draco looked at Soren, "Will this old guy cause trouble for us?"

"With Dumbledore here, he won't be too much. At most, you should pay attention to him." Sauron narrowed his eyes, his golden eyes shrank into a thin line. "We can be considered old acquaintances. I once left some souvenirs for him, and I hope he still likes them."

Seeing the sinister expression on Sauron's face, Draco and others looked at each other, but they all remained silent in tacit understanding. It was obvious that Sauron and the crazy-eyed man had some unpleasant interactions...

Section 2

Amid the monotonous sound of the wheels pressing over the rails, the Hogwarts students finished their day's journey. When they got off the train, the rain was soaking and violent. The students were wet but helpless, and could only stand in the crowd and move little by little, walking through the dark and slippery platform. Outside the station, a hundred carriages were waiting for them, heading towards the rugged path leading to Hogwarts Castle.

Before boarding the carriage, Sauron caught a glimpse of Harry and his friends from afar. They were rushing towards another carriage in a mess, as if they had noticed something. Harry turned around and looked over, but only saw the carriage gradually fading away.

Due to the strong wind, the carriage shaking violently made Isabella on the side complain softly. Sauron closed his eyes and leaned on the seat. In his perception, Hogwarts got closer and closer. When the carriage passed through the gates with winged boar sculptures on both sides and drove into the spacious driveway, Sauron sensed that he had passed through an invisible barrier and entered a huge spiritual field.

Since the first time he stepped into Hogwarts, Sauron has noticed the existence of this spiritual energy field, but to this day, he is still shocked in his heart, especially since he has just completed a further transformation, he can more clearly feel the extraordinaryness of the legendary magic that guards Hogwarts.

Many people know that Hogwarts is protected by various magic, keeping it away from the outside world's spy, but few people know that these magic is not independent of each other, but together form an orderly magic system - a spiritual field controlled by magic is constantly in a void that ordinary people cannot detect, connected with the underlying rules of the world in a special way, and influences the operating mechanism of matter and energy in this space through various complex and exquisite logical algorithms, thus perfectly realizing the various functions of the system itself.

Everything within the school has some connection with the spirit field, including those entering the school - everyone's spiritual energy will be sensed by the spirit field, forming an invisible magic link, and then be included in the full-time monitoring by the entire magic system. Everything is completed quietly in an instant, so that almost no one can notice it - of course, almost no one.

Just last year, Harry got a live spot map that could identify the name and location of everyone on campus. Obviously, the map maker was aware of the existence of this magic system to some extent, and successfully cracked some system functions and imported some monitoring data onto the map. Later, Sauron learned that his father was one of the genius makers of the map.

Now, Sauron can do much more than his father. In the past three years, he has often used the power of the demigod to disrupt the rules of the spiritual field, thereby using phantom manifestation or evading the monitoring of the system. However, now, Sauron has not done anything deliberately and is included in the monitoring of the spiritual field like others. In fact, with the power of the demigod level, he has the ability to obtain more system permissions, or even completely destroy or take over the system. However, before all this happens, the owner of the highest authority of this magic system will never sit idly by.

Sauron "sees" that in this dark blue psychic energy, with the gathering of magic links, the color becomes brighter and brighter, and at the center of all this is a burning golden flame. The flame is so bright that it even dyes the surrounding spiritual energy fields golden. Sauron knows who it is - Abuth Dumbledore, the principal of Hogwarts, is probably the most powerful demigod in the world. To this day, Sauron does not think he can defeat Dumbledore, at least he cannot build a system architecture alone, let alone manipulate it in human form.

In Sauron's opinion, this magic system can be called the pinnacle of magic technology. Compared with it, the "Silk" system of the British Ministry of Magic is so simple that it is not worth mentioning. Of course, this is also related to the fact that the "Silk" system has not been truly completed - before it was completed, its designer Voldemort broke up with the Ministry of Magic, leaving only a semi-finished product full of back doors, so that the Ministry of Magic can only use it to monitor the casting of underage wizards.

But the most interesting thing is that with Sauron's understanding of the origin of magic, both the spirit field system in Hogwartsli and the Ministry of Magic's Trace gave him a sense of increasingly obvious familiarity, which evoked the memories deep in his mind - the memories of his previous life, as a mortal.

The spirit field system, tracer, and other newly born magic theories and technologies all show a trend, that is, there are more and more similarities with science and technology, partly reflected in specific structures and functions, and more in ideas and ideas. Thanks to the experience of the two lives, Sauron figured out the reason early on - since the two systems coexist in the same objective world, they must be based on the same underlying rules, and the only difference is the different directions of analysis and utilization of rules. This means that with the continuous development of magic and science, the unity between the two systems will become more and more obvious until they are integrated into a highly developed new system.

Because of this, all modern demigods - Sauron, Dumbledore, Grindelwald and even Voldemort, are real Muggle masters. With their own advanced life forms, demigods draw various knowledge from the world of mortals, analyze the rules of this world more and more in-depth, and master more powerful power until they complete the ultimate transformation.

Sauron also knew that wizards knew nothing about the Muggle world they mentioned. More and more wizards are aware of the huge power brought by the combination of magic and technology, and have achieved results in practice. It is foreseeable that with the continuous integration of magic and technology, an unprecedented theoretical and technological revolution is coming, and the entire human world will undergo earth-shaking changes.

Soren couldn't help but think of Mr. Weasley, who worked in the Ministry of Magic, was the head of the Department of Prohibition of Abuse of Muggle Products - although in many people, this department is the most useless in the Ministry of Magic. Considering the upcoming technological revolution, Soren never thought that Mr. Weasley had insisted on working in this department for decades, just to facilitate the collection of Muggle wire plugs...

In this way, in Sauron's chaotic thoughts, the short trip on the carriage was soon over. When the carriage stopped under the stone steps in front of the two oak gates, Sauron and Isabella walked out of the car door. In front of them, Hogwarts' towering castle stood quietly under the sky. Sauron shook off all the chaotic thoughts in his mind and slowly walked into the tunnel leading to the castle with the flow of people. In front of him, more disputes and challenges were waiting for him.
