Section 1: In a train station where people were coming and going, Sauron appeared silently in the bustling crowd. Dense raindrops fell on his black robe, and then slipped down silently, turning into mud under his feet. The air was filled with the unique smell of machinery. On the railway track nearby, the train bound for Hogwarts was already in place. The dark red steam locomotive was dragging a long passenger compartment, waiting for the travelers who were about to travel a long distance. Parents are bidding farewell to their departing children, classmates who have not seen each other for a long time are greeting each other, owls are squeaking, and many children are looking around, excited or uneasy waiting for the first departure in their lives. Home travels. But all this has nothing to do with Sauron. He walked through the thick smoke emitted by the locomotive alone, not caring about others, and no one cared about him. Occasionally, someone saw his eyes inadvertently, and they hurriedly looked away, showing his face. Move aside in fear. Sauron got on the train and walked straight towards the front of the car. He found an unoccupied compartment and sat in. Students were walking back and forth in the corridor. During this period, several Hufflepuffs broke in. After seeing Sauron, He hurried out again. Soren sat on his seat, minding his own business and reading the Lonely Planet written by Mr. and Mrs. Wheeler in his hand, just like an ordinary traveler, killing time before the train departed. The door of the compartment was pushed open again, and then someone sat opposite Solan, carrying a faint scent of roses. "Nice perfume." Sauron looked at the book in his hand and said without raising his head, "It seems you are in a good mood, Isabella." "Thanks to you, I had a good holiday." Sabella leaned on her seat and looked at the book in Sauron's hand with interest, "Why, are you starting to be interested in Muggles?" "Actually, I know more about Muggles than you think. Soran put down the book and looked at the girl opposite. He noticed the flash of surprise on her face. He smiled and said, "Why, are you surprised?" Soran knew why she was surprised - of course. Not because he read the travel guide, but because of his eyes, the golden pupils are deep and sharp, without any cover-up. "Do you plan to keep doing this?" Isabella asked with raised eyebrows. Of course she would not think that Sauron was doing this against her, because it made no sense and was not in line with his usual style. So the only explanation is that he doesn't He plans to continue hiding his identity as a demigod. "Why not." Soran said nonchalantly. He turned to look out the window. The crowd seemed to be much thinner 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 sat down in the armchair to read. Time passed by, and when the train whistle sounded sharply before departure, Draco also walked into the compartment, along with Crabbe, Goyle and Pansy. Soon, the train left the city and entered the wilderness, heading north. The rain became heavier and fiercer. The sky was dark and the car windows were covered with moisture, so lanterns were lit in broad daylight. Seeing Sauron's eyes, Draco and the others couldn't help being stunned for a while, but they soon stopped caring. Except for Draco, the other three more or less avoided Sauron's sight. After a brief exchange of greetings, a few people chatted and passed the time on the train. "What happened at the World Cup made Fudge very anxious." Draco looked at the Daily Prophet in his hand and smacked his lips. "The media is chasing the Ministry of Magic like dogs, and now the Americans and Germans are getting involved " "It's not surprising. There is still half a year before the Wizards Alliance's Joint Ministerial Meeting. More than twenty important issues will be decided, at least half of which are related to the formulation of new magic technology standards, which involves huge and terrifying economic interests. Those politicians and the interest groups behind them may not look good." Pansy said, curling her hair with her fingers. She looked at Draco with a meaningful smile on her face, "I heard that Uncle Malfoy. Recently, he has been keen on charity work and donated a large amount of money to St. Mungo's, which is enough to build another hospital" "Come on, Pansy, you sound like a cynical old scholar." Draco. He glanced at Pansy and said nonchalantly, "If I remember correctly, didn't your family also sponsor a large sum of money to the Ministry of Magic to host the Triwizard Tournament?" Pansy snorted and twisted. Ignoring Draco, Isabella put down her book and looked at Sauron, "When it comes to the Triwizard Tournament, will you participate in it?" "Forget it, I won't join in the fun." Sauron shook his head, "I bet if I participate, letters of protest will be piled up in the Slytherin lounge." Everyone laughed, and Draco continued: "That's not bad, at least Slytherin Can win the top three championship.?There is a distant cousin in Durmstrang. It is said that their school has been organizing students to train during the holidays to prepare for the Triwizard Tournament. " "That's not surprising, considering who their principal is - Igor Karkaroff, that old fox. "Isabella said with a sneer, her contempt and disdain evident. She obviously didn't have a good impression of the principal of Durmstrang. "Well, actually, I really want to go to Durmstrang to see him. "Draco said with some regret, "It is said that their attitude towards dark magic is much more open than Hogwarts. They really teach dark magic, not the funny Defense Against the Dark Arts like Hogwarts. " "If you say that, Dean Snape will be sad. "Isabella said jokingly, "He has always wanted to teach this class. " "Haha, I'm afraid there is something even more saddening for my godfather. "Draco said with a smile, "I heard from my father that Dean Snape will be disappointed again this year. But you may never guess who will be the Defense Against the Dark Arts teacher this year. " "Who knows, it can't be a vampire. Pansy said, "But to be honest, that werewolf's class is quite interesting." " "It's Mad-Eye Moody! "Draco lowered his voice and said, "I didn't expect that Dumbledore actually asked him to be his teacher. " Several people were silent for a while. Draco's eyes swept across several people and found that except for Sauron's face, which showed no emotion, several others showed more or less surprised expressions. It was obvious that they all I knew Mad-Eye, but I didn¡¯t expect to deal with him at Hogwarts this year. ¡°That old madman, his attitude towards Slytherin is not friendly. Pansy said with a frown. "Actually, his attitude towards most people is not friendly. "Isabella said, "That guy is a paranoid lunatic, but he is really powerful. Until he retired a few years ago, half of the people in Azkaban were sent to him by him. " "What do you think of this? Draco looked at Sauron, "Will this old guy cause trouble for us?" " "With Dumbledore here, he won't go too far. At most, you just need to be careful in front of him. Sauron narrowed his eyes, and his golden pupils shrank into a thin line, "We are old acquaintances. I once left him some souvenirs. I hope he still likes it." " Seeing the sinister expression on Sauron's face, Draco and the others looked at each other, but they all remained silent in a tacit understanding. It was obvious that Sauron and Mad-Eye had some unpleasant interactions Second Plot: The students at Hogwarts ended their day's journey with the monotonous sound of wheels rolling over the rails. When they stepped off the train, the rain fell quickly and fiercely. The students were soaked but had no choice but to They stood in the crowd and moved slowly across 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 a distance. They were rushing toward another carriage in a panic. Harry seemed to have noticed something. He turned around and looked over, but he only saw the carriage going away. The wind was strong and the carriage shook violently, causing Isabella on the side to complain softly. Sauron closed his eyes and leaned on the seat. In his perception, Hogwarts was getting closer and closer. Passing through the gate with winged boar sculptures on both sides and driving onto the spacious driveway, Sauron felt that he had passed through an invisible barrier and entered a huge spiritual field. From the first time he set foot in Hogwarts. , Sauron has been aware of the existence of this spiritual energy field, but to this day, he is still shocked by it in his heart, especially since he has just completed further transformation and can more clearly feel the legend that protects Hogwarts. The Extraordinary Magic Many people know that Hogwarts is protected by various magics, keeping it away from the prying eyes of the outside world, but few people know that these magics are not independent of each other, but form an orderly magic system together. ¡ªA spiritual field controlled by magic is kept in a void that is invisible to ordinary people. It is connected with the underlying rules of the world in a special way and affects the matter in this space through various complex and exquisite logical algorithms. and energy operation mechanism, thereby perfectly realizing the various functions of the system itself. Everything within the school has some connection with the spiritual field, including the people who enter the school-everyone's spiritual energy. It will be sensed by the spiritual field, forming an invisible magic link, and then being included in the full-time monitoring of the entire magic system. Everything is done silently in an instant, so that almost no one can notice it - of course, But almost no one. Just last year, Harry got a Marauder's Map that identified the names and locations of everyone on campus.? Obviously, the map maker was aware of the existence of this magic system to some extent, and successfully cracked some of the system's functions and imported some of the monitoring data onto the map. Later Sauron learned that his father was one of the genius makers of maps. Now, Sauron can do much more than his father. In the past three years, he has often used the power of demigods to confuse the rules of the spiritual field, thereby using phantoms or evading system monitoring. But now, Sauron has not done anything deliberately and is being monitored by the psychic field like everyone else. In fact, with the power of the demigod level, he is fully capable of obtaining more system permissions, and even completely destroying or taking over the system. However, before this happens, the owner of the highest authority of this magic system will never sit idly by. Sauron can "see" that in this blue spiritual energy, as the magic links gather, the color becomes brighter and brighter, and at the center of it all is a blazing golden flame. The flames were so bright that they even dyed the surrounding psychic field golden. Sauron knew who it was - Albus Dumbledore, the Headmaster of Hogwarts and possibly the most powerful demigod in the world. To this day, Sauron does not think he can defeat Dumbledore, at least he cannot build the system structure alone, let alone control it in human form. In Sauron's opinion, this magic system can be called the pinnacle of magic technology. Compared with it, the "Tracing Silk" system of the British Ministry of Magic is too crude to be worth mentioning. Of course, this is not the same as the "Tracing Silk" system. Not really completed - before it was completed, its designer Voldemort fell out with the Ministry of Magic, leaving only a half-finished product full of backdoors, so that the Ministry of Magic could only use it to monitor underage wizards Cast a spell. But the most interesting thing is that as Sauron understands the origin of magic, whether it is the spiritual field system in Hogwarts or the traces of the Ministry of Magic, they all give him an increasingly obvious sense of familiarity, which evokes The memory deep in his mind - the memory of his past life as a mortal. Spiritual field systems, trace silk, and other newly born magic theories and technologies all vaguely show a trend, that is, they are more and more similar to science and technology, which is partly reflected in the specific structure and function. It is more reflected in concepts and ideas. Thanks to the experience of two lives, Sauron figured out the reason very early - since the two systems coexist in the same objective world, they must be based on the same underlying rules. The only difference is the analysis and utilization rules. The direction is different. This means that as magic and science continue to develop, the unity between the two systems will become more and more obvious, until they merge into a highly developed new system. Because of this, all the demigods in modern times - Sauron, Dumbledore, Grindelwald and even Voldemort, are true Muggle-savvy. Relying on their own advanced life forms, demigods absorb various knowledge from the mortal world, analyze the rules of this world more deeply, and thereby master more powerful power until they complete the ultimate transformation. Sauron also knew that wizards were far from ignorant of the Muggle world they spoke of. More and more wizards are aware of the tremendous power brought by the combination of magic and technology, and have already achieved results in practice. It is foreseeable that with the continuous integration of magic and technology, an unprecedented theoretical and technological revolution is about to come, and the entire human world will undergo earth-shaking changes as a result. Sauron couldn't help but think of Mr. Weasley, who worked in the Ministry of Magic and was the head of the Department for the Prohibition of the Misuse of Muggle Supplies - although in the eyes of many people this department is the most useless one in the Ministry of Magic. Considering the coming technological revolution, Sauron would never think that Mr. Weasley had persisted in working in this department for decades just to collect Muggle wire plugs In this way, in Sauron's chaotic thoughts, the carriage The short trip was over quickly. When the carriage stopped at the stone steps in front of the two oak doors, Sauron and Isabella walked out of the carriage. In front of them, the towering castle of Hogwarts stood quietly under the sky. Sauron put aside all the messy 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.
