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

Clang, clang, clang... Three more arrows shattered the Iron Armor Spell that Su Yu had just summoned, but the next few arrows grazed past Su Yu.

It was clear that the centaurs hadn't missed; rather, the chain on Su Yu's hand had played a role, allowing the centaurs to make adjustments at the last moment before firing their arrows.

The clatter of hooves sounded, and five centaurs galloped out of the forest. Su Yu observed them for a moment, but Ferenze, whom he had encountered last time, was not among them.

Moreover, these centaurs were not friendly to him. Although they stopped shooting arrows, they still held spears and warily surrounded Su Yu.

Surrounded like this, Coal Ball and Su Yu were furious. The arrows that the centaurs had just shot were clearly meant to kill them. If they hadn't been strong enough, they would probably be corpses by now.

Coal Ball arched its body, baring its fangs, its expression fierce, and let out a low growl, ready to pounce at any moment.

Su Yu was also furious, but he still retained his rationality. He patted the coal ball with his hand and angrily rebuked the centaurs, "Is this what you call centaur friendship is like?"

The centaur leader snorted and gestured for the other centaurs to put away their weapons. Su Yu looked at him; this guy was the complete opposite of Ferenze.

Ferenze is white-haired with long silver hair, while this guy has black fur all over his body, with short, messy brown hair.

"I am Bane, the captain of the centaur hunting party. Human, why are you harming unicorns?" Bane asked arrogantly, looking down at him.

“I am Professor Su Yu of Hogwarts. Which eye of yours saw me harm a unicorn? Do you centaurs act solely based on wild guesses with your waterlogged brains?” Su Yu said bluntly.

"How dare you insult us centaurs!" Bain raised his spear again and thrust it forward, almost touching Su Yu's face.

Shot with arrows and threatened with spears, even after revealing his identity, Su Yu couldn't help but feel angry, even if he knew what the right choice was.

"If I don't show my power, you'll really think I'm a pushover?" Su Yu waved his wand, using Apparition to create some distance, then pulled out two magic pistols and began unleashing firepower at the centaurs around him.

The saying goes, "When in dire straits, use tactical infiltration; when in a favorable situation, use firepower coverage." Su Yu has brought this tactical concept to its extreme at this moment.

He held his hands outstretched, and the magic gun fired at a rate of four shots per second. Blue flashes occasionally illuminated Su Yu's face, adding a touch of coldness to his already handsome appearance.

Although each spell only has a power of LV6-LV7, the centaur itself is not a high magic resistance unit. Once hit once, it is basically impossible to dodge subsequent attacks.

The spell Su Yu chose wasn't a high-damage spell, just a simple sleeping spell. But the centaurs had never seen such a dense spell before, and they scattered and fled like frightened rabbits.

Five seconds later, all five centaurs collapsed to the ground, four of them unconscious, while only Bane was still struggling to get up.

Bain looked at Su Yu, his eyes filled with anger, resentment, horror, and a hint of regret. Of course, he knew who Su Yu was, and he also knew that the bracelet in Su Yu's hand represented the friendship of the centaurs.

Knowing why Su Yu obtained the bracelet, Bain was able to conclude that Su Yu was not the one who harmed the unicorn when Su Yu revealed it.

However, Bain was a hawk in the centaur tribe. He always believed that wizards were an untrustworthy group. When the decision was made to give the bracelet to Su Yu, he also objected, but the Grand Elder made the final decision.

Since Su Yu had produced the bracelet, Bain recognized it, but his ingrained way of thinking filled him with suspicion and hostility, leading him to choose to confront Su Yu with an antagonistic attitude.

But now things have turned out this way. He will inevitably be punished after returning to the tribe. What Bain didn't expect was that Su Yu had already come to his side.

Su Yu removed the chain from his wrist and disdainfully flicked it across Bain's face, coldly saying, "Go back and tell Ferenze that I, Su Yu, disdain to accept this cheap and inferior friendship from the centaurs."

"And let me remind you one more thing: put away your unfounded arrogance. Not every wizard is as kind as me and will spare your life."

"As for the person who hurt the unicorn, I'll find him. You bunch of idiots don't need to worry about him!"

After saying that, Su Yu, carrying Coal Ball, continued to track the scent of unicorn blood.

Su Yu didn't know if his actions would make the centaurs hostile towards him, but since he had already done it, he didn't regret it. Anyway, he had the moonstone in his hands, and he could just stop dealing with the centaurs in the future.

As for whether the four centaurs were in danger while unconscious here, Su Yu was not worried. Centaurs themselves knew some healing magic, and although Baine seemed weak now, he would be back to his lively self in no time.

After traveling through the forbidden forest for about 20 minutes, Su Yu finally spotted the unicorn by a small river. Its moonlit silver-white fur was dreamlike and ethereal; just one glance was enough to bring peace and tranquility to one's soul.

Unfortunately, the unicorn was lying by the river, occasionally letting out a mournful cry, and a cloaked black figure was perched on its body.

Chapter 47 Avada Kedavra

Su Yu hid behind a big tree, watching everything that was happening by the river from afar. Judging from the frequency and tone of the unicorn's howls, it wouldn't be long before it died.

According to Su Yu's plan, after Voldemort left, he would go out and collect some blood. If the unicorn was still alive at that time, he would not mind saving its life.

"Why are you hiding? Come on!" The coal ball made a gurgling sound from the side, and Su Yu understood its meaning through the mental link.

"Shh! What do you know? Why are you going? That guy is really tough!" Su Yu held up a finger, telling Coal Ball to keep his voice down.

Coal Ball, however, remained unfazed and continued snoring: "Didn't you tell me to keep an eye out for anyone hunting unicorns? Why are you chickening out now? If you won't go, I will!"

Su Yu quickly grabbed Coal Ball: "Why are you going up there? You don't even know that unicorn, what does it have to do with you?"

“Unicorns are the embodiment of nature. They can heal the wounds of other animals. In the forest, no animal will hunt a unicorn unless it is a demon. All magical creatures will also come to the rescue when they encounter a unicorn being hunted.” Coal Ball struggled, clearly wanting to save the unicorn.

Su Yu didn't know how Coal Ball knew about these things. Perhaps it was a memory passed down in its blood, or something else entirely. But the commotion between the man and the beast seemed a bit too much, and had already attracted attention over there.

Seeing that the man in black was about to turn around, Su Yu had no choice. He couldn't let Coal Ball face Voldemort alone, so he steeled himself and said, "Alright, you better behave yourself. I'll handle this."

As he spoke, Su Yu took out his phone and sent Dumbledore a message: "Forbidden Forest, Help!"

Just before the man in black robes turned around, Su Yu stood up, took his magic wand, and walked out: "What kind of monster are you, daring to harm a unicorn? Let it go!"

As he spoke, Su Yu pointed his wand to the sky, and a dazzling white light shot up, forming the shape of a raven spreading its wings high in the night.

That's right, Su Yu was sending out a distress signal. Although he really wanted the unicorn's blood and wanted to protect Coal Ball, all of this had to be based on the premise that his own life could be guaranteed.

He didn't know whether the guy in front of him was Quirrell or the remnant of Voldemort, but he was definitely very dangerous. Even if Dumbledore didn't look at the telepathic message, he should be able to see such a large magical signal.

The man in black robes on the ground had turned around completely. He was also very surprised that Su Yu had chosen to call for reinforcements without any prior communication.

"You bastard, you busybody!" the black-robed man roared angrily, and a killing intent as real as a physical force immediately locked onto Su Yu, making his hair stand on end and his legs go weak.

"Avada Kedavra!" The man in black robes pulled out his wand and chanted a spell. A dark green light shot out from the tip of his wand, illuminating the surroundings. Under the eerie green light, the entire forest looked like a hellish landscape.

Having traversed this world for thirty-one years, Su Yu had never personally witnessed the Killing Curse. He had heard countless legends about Voldemort and seen many of the corpses he had killed.

But before stepping forward, Su Yu remained confident that he was absolutely capable of saving his life from Voldemort's remnant soul.

But when he saw that green light, he realized he was terribly wrong when faced with that terrifyingly murderous incantation.

Su Yu felt his body almost completely stiffen, unable to dodge normally. Even the magic power within his body seemed to be frozen by the killing intent, rendering him unable to move.

Of course, killing intent doesn't possess these magical abilities. This was merely a stress response Su Yu had when facing such intense killing intent for the first time, much like how an ordinary person is unable to quickly escape when faced with something extremely frightening.

This also shows that the gap between the two sides is too great. As the Death Curse gets closer and closer to him, Su Yu regrets his recklessness and his underestimation of his opponent.

With a bang, the Killing Curse activated Su Yu's first passive defense line, trigger-activated armor. This thing had saved Su Yu many times, but this time it was quickly melted through as if it were a piece of styrofoam.

Am I going to die? No, Su Yu roared inwardly in unwilling anger. Suddenly, he felt something bump against his waist. Out of the corner of his eye, he saw it was Coal Ball.

But the coal ball knocked herself away. What will she do? Will she be struck by that deadly curse?

Su Yu's mind raced, as if he had returned to that summer when he first arrived in America, when he was targeted by a dark alchemist skilled in mind control.

Although the others eventually escaped, several of their technologies were stolen. In order to create an anti-escape tool, Su Yu ventured deep into the Rocky Mountains, intending to use cats and leopards as test subjects.

His plan initially went very poorly because the cat-leopard was too fast for him to get close. Secondly, the cat-leopard was very powerful; he could protect himself with his alchemical tools, but catching it was impossible.

Until he met Coal Ball, an animal born with a mutated coat color was not accepted by nature. Coal Ball was abandoned by its mother because of this. As a young child, it was unable to hunt for itself and was about to die.

Su Yu didn't know that Coal Ball was a cat-leopard at first; she took her in purely out of kindness, providing her with food and shelter.

And so, the man and the leopard spent a long time in the Rocky Mountains, until Su Yu successfully created the Anti-Levitation Necklace and, with the help of Coal Ball, killed the dark wizard and obtained his start-up capital in America.

For nearly a decade afterward, they were inseparable and even developed a deep connection. For Su Yu, Coal Ball was perhaps the most cherished partner in the world.

The coal ball cannot die, absolutely not. At this moment, a warm current surged through Su Yu's body, and his magic power and body suddenly seemed to be activated by something, breaking through the blockade of that killing intent.

Su Yu raised his wand and shouted, "Protect the Gods!"

A silver raven flew from the tip of Su Yu's wand and collided with the dark green spell. Upon contact, the silver raven let out a mournful cry and was shattered into pieces.

Fortunately, the deadly curse was also exhausted and disappeared into thin air. Seeing that his attack had failed to kill Su Yu, the man in black immediately prepared to launch a second attack.

But the coal ball had already moved after landing. The cat-leopard was incredibly fast, like a streak of light, and rushed in front of the man in black before he could finish the spell, biting his hand that was holding the wand.

"Bastards! I will kill you all, I definitely will!" After saying that, the man in black turned into a wisp of black mist and quickly disappeared into the distance.

Seeing that the man in black had finally left, Su Yu got up from the ground and breathed a sigh of relief. He was certain that the one who had just cast the Killing Curse was Voldemort, only a battle-damaged version.

Su Yu remembered a saying that circulated in the magical world: love is the greatest magic in the world.

Su Yu used to scoff at this, believing that magic is magic and has nothing to do with love.

But just now, the power that erupted from his spell surprised even himself. For the first time, Su Yu realized that perhaps that statement was true.

However, Su Yu didn't think too much about it. He quickly went to the unicorn's side, waved his wand, and collected the blood that had not yet rotted into the cup containing the moonstone so that the magic runes could absorb the blood.

Then he squatted down in front of the unicorn, took out a bottle of healing potion from his seamless stretch bag, and poured it down the unicorn's throat.

Su Yu didn't know if this would work, but he didn't have any better ideas at the moment. About ten seconds later, a dazzling white light flew from a distance and landed in front of Su Yu. When the white light dissipated, the old man Dumbledore walked out from inside, as if a hero had made his entrance.

Upon seeing that it was Dumbledore, Su Yu couldn't help but say enviously, "Professor, your entrance was so spectacular! Could you teach me how?"

Dumbledore ignored him and went straight to the unicorn. Seeing that the unicorn's breathing was gradually stabilizing under the effects of the healing potion, Dumbledore waved his hand, and silver magical threads seeped into the unicorn's body, causing its external wounds to heal quickly.

“Professor Su, what are you doing here?” Dumbledore asked.

Su Yu pointed at Coal Ball: "Coal Ball has been wandering around the Forbidden Forest lately. She told me that someone was hunting unicorns, so I came to take a look."

Dumbledore nodded: "Thank you for your hard work, Sue. It's all thanks to you that we were able to save this unicorn."

Su Yu waved his hand and said, "Unicorn blood can prolong life, but it also brings a curse. Almost no one would do that unless they want to stall for time so they can drink another kind of healing potion!"

"You mean Voldemort?" Dumbledore asked.

Su Yu reviewed the experience again, making sure there were no mistakes, and nodded: "I think so. Although I didn't see his face clearly, the powerful and evil aura, and the ruthlessness of releasing the Death Curse right away, I think it could only be him."

Dumbledore knew, of course, that Quirrell was helping Voldemort steal the Philosopher's Stone, but he didn't expect that Voldemort had already arrived at Hogwarts. It seemed he had to be more cautious.

As time passed, the unicorn on the ground slowly recovered. It stood up, let out a hiss, and then lowered its head, as if to bow to Su Yu.

Then a silver light shot out from the unicorn's horn and entered Su Yu's body. Su Yu felt a warm current flow in, which felt very comfortable, and then nothing more happened.

Just as Su Yu was bathed in the silver light of the unicorn, a chaotic sound of hooves rang out, and more than a dozen centaurs rushed over and witnessed the scene.

Leading the group was Ferenze, and next to him stood a shocked Bain. Ferenze pointed at Su Yu and said to Bain, "This is what you call harming unicorns? How could someone who harms unicorns possibly receive their blessing?"

Bain naturally understood what Ferenze was saying. He stared blankly at the scene in front of him, never expecting that Su Yu would actually fulfill the Grand Elder's prophecy.

Centaurs don't lie. After returning, Bain truthfully reported his conflict with Su Yu, emphasizing that he had only suspected Su Yu of harming the unicorn, but Su Yu suddenly attacked.

So the Centaur Elder sent Ferenze and Bain to investigate the matter. Before leaving, the Elder called Bain aside and instructed him:

“Bane, Professor Su brought back a sacred relic of the Centaur people for us. Through the relic, I saw that in the dark night sky, the old morning star is already very old.”

"And a new morning star is rising, and they are converging. The unicorn's blessing will be bestowed upon the new star, helping him to become the new master of Hogwarts Castle."

“If Professor Su Yu wasn’t the one who hurt the unicorn, you should apologize to him and ask him to accept the centaur’s friendship again.”

The scene in the distance perfectly matched what the Grand Elder had said, meaning that Professor Su Yu would…
