Section 1

The bell rang and the corridor was filled with students who were rushing. However, walking through the crowd, Sauron walked calmly, and his invisible power cleverly opened a small piece of space around him, which made Isabella, who had been following him, much more relaxed.

"Warrington and the others came to me again in the morning. They wanted to know if you have time to guide their training." Isabella complained, frowned, holding a thick magic book in her arms. "Quidditch is gone, and now several people on the team are all thinking about participating in the Triple Championship. Almost all their free time is spent practicing spells-" She paused and added mockingly: "Of course, there is also going to the school hospital."

"A few days ago, when Iric ran to me with abscess on his head, I knew what stupid things they would do - what they thought they were going to participate in, the evil curse competition?" Soren sighed, "I bet that if I taught them a few more powerful spells, they wouldn't be able to wait until the third round began."

"I have to admit that Warrington and the others are not very clever. Maybe they are hit too hard by the roaming ball in their heads." Isabella shrugged, "They think that the school will select contestants in duel."

"Due to the duel, they can think of it." Sauron hummed, "Even you can beat them ten."

The little girl didn't say anything, but she still showed a smug smile on her face.

The two walked up the stairs and walked along the open-air corridor on the second floor towards the library. From here, you could see the lawn under the sun. The students after class were in groups of three or five, enjoying their afternoon leisure time. Isabella noticed that Sauron narrowed his eyes slightly and looked in the direction of the herb greenhouse. Following his sight, Isabella saw Harry and the other three walking through the low bushes and heading towards the hunting ground along the path.

"I remembered something about Harry," Isabella hesitated for a moment, and then said, "One time I went to see Professor Flevy and saw him practicing mantras alone in Professor Flevy's classroom."

Sauron raised his eyebrows, "So what?"

"Do you think he wants to participate in the Final Three?" Isabella said. "You put a lot of pressure on him, maybe he wants to prove himself."

"I hope his ideas are not that naive." Sauron said calmly, "What can even be the champion of the Final Three? As long as I think, one thought can crush a piece of it, just like crushing a bed bug."

Soren had a habitual contempt for all competitions, which Isabella had long been accustomed to. What she really cared about was Soren's expression when he spoke - he tightened his lips, narrowed his eyes slightly, and his pupils shrank into a narrow slit. Often followed Soren, Isabella knew that only when he was planning something in his heart would show such a look. Of course, the little girl responded with silence rather than asking about it. After all, being too strong curiosity is not a good thing.

"It's you, there are some things that need attention." Sauron said suddenly, and he glanced at the book in the little girl's arms. "Many of the magic in the Book of Winter Night is unresolved ancient magic. The method of guiding magic is very different from modern magic. Rampant use may cause terrible trauma to the caster, so you must not practice unless I am by your side."

"But Professor Flevy didn't tell me this when he lent me the book." The little girl couldn't help but defend herself.

"That's because he thought you could not read the above spells, and could only read books as ordinary documents." Sauron said seriously, "He didn't expect a third-grade student to understand ancient magic texts, and he didn't know how I taught you how to interpret ancient magic."

He turned to look at Isabella, frowned and said, "The desire for knowledge and exploration is a necessary quality for an excellent wizard, but more importantly, rationality and prudence. There is no shortage of amazing geniuses in history, but not many people can walk to the end safely in the end."

Sauron stretched out his hand and watched the little girl hand the book reluctantly. He shook his head, pinched the spine with one hand, and gently brushed the cover of the book with the other hand. His slender fingers slashed through the ancient dark brown leather, and painted magic patterns with no trace.

A faint blue light flashed by, and under Isabella's surprised gaze, Sauron returned the book to her again. The little girl opened the book in surprise, but soon the smile on her face collapsed again - except for those large narrative texts that were still clearly visible, all the magic texts recording the spells became blurred, as if they were shrouded behind a erratic fog, and they could not see clearly no matter what.

The little girl raised her head and found that Sauron had already walked farther and farther away on her own. She pouted in dissatisfaction, but she had no choice but to trot with a bitter face.

Section 2

In Hagrid's hut, Harry and the other two sat around a wide round table made of logs, holding a hot teacup in their hands, and the hunting dogs lie listlessly at their feet, making a whimper from time to time.

"Taits look exhausted," Ron said, watching Hagrid put a large plate of rock crusts on the table, without any intention of eating.

"Well, we just came back from the forest, and it's not very peaceful now." Hagrid muttered, and he used torches to fiddle with firewood in the stove, making them crack loudly, "A few days ago, a unicorn was attacked, near the night lake deep in the forbidden forest."

"Is it seriously injured?" Hermione asked half curiously and half worried.

"I don't know, but it seems that there is no big problem." Hagrid shrugged and said helplessly: "It's an adult male beast. It has a bad temper now. No one can get close to it. Whoever dares to go over will slash him with lightning."

"Lightning? Can unicorns use magic?" Ron was surprised.

"Of course, and it's amazing." Hager said disapprovingly, "Magic is not the patent of wizards. Many creatures are born to manipulate magic, but their spells are not as diverse as wizards' magic."

"But if that's the case, what dares to provoke it." Harry frowned, feeling a little uneasy in his heart.

Harry knew that Sauron's Phoenix had hurt a unicorn, but it was just a cub, which made him think of what happened when he first came to Hogwarts - Quirrell, possessed by Voldemort, once killed a unicorn to help Voldemort maintain his life.

"Whatever it is, it must be very powerful," said Hager. "I asked Aragork, and its descendants told it that the unicorn was subdued almost instantly, but even the attacker could not see clearly, as if the guy was always hidden in a shadow."

"Does Dumbledore know about this?"

"Of course." Hagrid said in a rough voice, "He doesn't seem to care much, but he just asked me to pay more attention. However, it's not difficult to understand. He has too many things to be busy with. He is about to hold the Triumph Championship, and he has to worry about so many things inside and outside."

It was not until an hour before supper that Harry and the other two refused Hagrid's invitation to see the tailburn together and hurriedly left the hut. The sunset drooped, and a golden ray of glow was dyed in the sky. They walked along the curved path towards the castle. On one side, the Forbidden Forest seemed mysterious and gloomy under the increasingly dim sky.

"What do you think the attacker would be?" Hermione said. "The descriptions of those spiders are too vague. It sounds like the attacker is using some kind of magic that manipulates darkness and shadows."

"Maybe the attacker just hid behind a stone, and gave the unicorn a bit of a cruel thing." Harry shrugged and said, "It's not surprising. Although those spiders have eight eyes, their brains are not very good. It's already good to express the general meaning."

"No matter what, don't even think of pulling me to ask those furry guys. Do you remember that their brains are very useful when they want to eat people." Ron shrank his neck and said with lingering fear, "To be honest, maybe it was the spiders who did it themselves, or a large snail."

"Oh, my God." Harry said, imagining what a snail that was so big that it could hurt a unicorn would look like. He suspected that if Hagrid's snail could really grow that big, no one would dare to come to Hagrid for class.

"You can get a lot of extremely valuable magic materials from unicorns, such as their blood and horns." Hermione said, "The ones that are more commonly used are unicorn tail hairs. Many people's magic wand cores are made of their tail hairs."

"Dumbledore is not very worried about this, right?" Ron nodded, "Maybe he knows who did it. Let me think about it. Maybe it was a professor who was a little tight, who took advantage of the night to pull a handful of hair off the unicorn's butt."

The three of them laughed, and the tall figure of the castle became clearer and clearer in their sight. By the time they passed through the gate and returned to the brightly lit hall, they had already forgotten the unicorn matter.

The dining table was filled with hungry students, waiting for a sumptuous dinner with anticipation. Harry and the other two sat down for a while, and the sumptuous dinner appeared on the table in front of them. Ron couldn't wait to scoop a large spoonful of bacon mashed potatoes for himself, while Harry and Hermione chewed the sausage while discussing where to go tomorrow to spend the first weekend since school started.

"Harry." A familiar voice suddenly sounded. Harry was stunned and turned around subconsciously to look at him. He saw Sauron standing at Slytherin's dining table and looking at him. He didn't speak at all, but the sound came directly into Harry's mind, clearly audible.

"Train, before sunrise tomorrow, I will come to see me alone on the lake shore."

Section 3

In the early morning of early autumn, the mist has not yet dissipated. Under the dark blue sky, the towering and cold figures of distant mountains can be seen vaguely. The wind whistled through the valley, passed through the lake, and with the breath of the wilderness, it turned into a deep sigh, disappearing into a tranquility.

This is the early morning of Hogwarts, and the ancient castle stands on this land guarded by magic, quietly waiting to wake up from sleep. On the low hills by the lake, a figure appears silently, and the black robe and erratic shadows slide gently across the wet grass.

The visitor was Soren. He stood on this not-high slope, his eyes passed through the misty lake and looked at the black forest in the distance. After a while, he opened his arms and turned into a ghostly shadow, flying towards the opposite shore against the lake.

On the other side of the lake shore, someone had already been waiting here. When Sauron showed his figure from the shadow again, the man turned around and revealed a face that was exactly the same as Sauron.

"I thought I would come earlier than you," Sauron said, looking at his twin brother, "but that's fine, at least we can set out now."

Harry didn't say anything, but nodded, and the two walked slowly towards the depths of the forest one after another. The ground was full of fallen leaves, and in a quiet state, the sound of their low footsteps and the sound of birds coming from time to time were clearly heard. After a long time, it was not until the vast lake completely disappeared into the layers of trees that the two stopped.

A small piece of clearing in the forest, through the sparse branches and leaves of the trees, the light blue sky could be seen. Sauron turned around, took out a small bottle from his arms, and threw it to Harry.

"Drink it, it's good for you," Sauron said.

Ha looked at the bottle in his hand with a raised eyebrows. It contained a dark blue liquid, which continued to flow slowly, shining with wisps of silver light. Even if it was just held in his hand, Harry could feel the powerful magic contained in it. After hesitating for a moment, Harry opened the bottle cap and drank the liquid in one gulp - it felt very wonderful, with almost no smell, like a cold air entering the stomach along his throat, and then spreading to his whole body, making him feel like he was bathed in cold water.

Harry couldn't help but shivered, but the coldness flew in a flash, and felt a full vitality fill his body, the fatigue of getting up early and the hunger on his empty stomach were wiped out.

"Now, let's talk short." Sauron looked at Harry, his golden pupils glowing in the darkness. "Maybe you've noticed that your power has been leaping up by leaps and bounds over the past period of time. Even if you don't deliberately practice, you can still use a lot of magic you didn't dare to think of before."

Harry nodded and said calmly: "Your training for the previous month was very effective."

But Sauron shook his head and said slowly in a plain tone:

"The power of magic changes, but in the final analysis, it is essentially the rule of perception of the world, and then use its own spiritual power to guide the surrounding matter and energy. In other words, the power of the wizard comes from the resonance between the heart and the world." He paused, and a contemptuous smile appeared on his face. "However, most wizards cannot truly do it after their entire lives. They are trapped in their shallow understanding of themselves and the world, and will never be able to reach truly powerful power."

Sauron raised his hand, and the black flames burned quietly in the palm of his hand, which made Harry frown. Harry could feel the terrible power contained in the faint flame, and at the same time, an indescribable hostility arose from the bottom of his heart.

Sauron noticed Harry's reaction, but he didn't seem to care.

"There are only a very small number of people-" He stared into Harry's eyes, with uncovered pride in his voice, "He can recognize his true self, accept the cold reality, and explore the supreme power hidden in the truth."

"I don't think I'm superior," Harry said sarcastically, "maybe I'm not as pretentious as you."

Soren did not refute, but showed a sneer. The next moment, a raging black fire suddenly ignited around him, and the surging magic power penetrated his body, stirring every inch of space around him.

For a moment, Harry felt as if he was in a dark abyss, and the oppression of mountains and seas almost suffocated him. However, Harry did not retreat. He instinctively used the power that emerged from the depths of his heart, like a flame that had never been extinguished in the darkness, supporting him to fight against the person in front of him - he raised his chest, his pale silver pupils became narrow and sharp, and he looked at Sauron firmly, and the hem of his robe sounded in the wind stimulated by Sauron's magic.

"Your power has awakened, your soul has begun to transform, my dear brother!" Sauron said, a cold voice roaring, coming from all directions. He snorted coldly, and the majestic power swept past like waves, and the thick trees broke one after another in the roar, and then were crushed to pieces in the destructive power. In the blink of an eye, everything within dozens of meters around the two turned into dust.

"This is extraordinary power, the most primitive instinct, the strongest desire." Sauron shouted, "understand it, control it, otherwise, he will only be transformed into ashes with everything you cherish!"

Harry was stunned, a hint of confusion appeared in his eyes. Sauron's words echoed in his ears, and countless scenes from imagination or reality flashed in front of his eyes. Gradually, he reappeared in his eyes. He stretched out his hand, clenched tightly, and sensed the call from the depths of his heart.

"What should I do?" Harry asked simply.

Sauron laughed, and his laughter became deep and distant under the blessing of magic.

"Faced with the truest self-" he said slowly, "We are walking on the road where we cannot turn back. If we want to be strong, we can only experience painful torture and unyielding battles."

The black flame turned into a magic wand, and was held in Sauron's hand. He looked at his younger brother and said word by word:
