It is difficult for people who have not been exposed to the wizarding world to understand what the so-called potions science is all about, just as Li Zu can try to imagine it, but still can't understand why slugs with tentacles are put into the material, and this is the key ingredient for treating scabies.

In addition to the difficulties in making potions, Li Zu has a very strong interest in this subject, and is not under magic at all, such as the elixir that can increase good luck, which may allow him to accomplish what he wants more easily when he explores the new world next time, or the elixir of immortality, I believe that no one will refuse to live longer.

When Li Zu found the half-blood prince, he was staying in his office, and several Slytherin students were asking for advice on potions.

The last people to see at Hogwarts had to be Leezu and Professor Bubbaghy, and none of the Slytherins who believed in the theory of noble blood had ever been willing to listen to a Muggle lecture.

This is the school, and they reluctantly shouted "Professor Li" before turning around and leaving the office.

The office door closed, and Li Zu looked at Snape, who almost had the words "I am a Death Eater" written on his face, and suddenly had an idea, what if he killed Snape and replaced it with his own toy? However, the idea required a certain amount of operability, as he was not sure that his toys would be able to use magic.

On the scientific side and on the magic side, the possibility of sharing is very small.

But there is value in experimentation.

However, it is not possible at Hogwarts, it is likely to be discovered by Dumbledore or a certain professor, and the magic plants and magical beasts here may have eyes or ears, which is easy to startle the snake, Li Zu thought carefully in his heart.

"You've been staring at me for a long time, Professor Li," Snape couldn't stand the staring look at him at first, and he said, "What's the matter with me?" ”

Li Zu didn't bend around, he said bluntly: "Buy some potions, or ask you to help refine potions." ”

"I'm a professor at Hogwarts and the head of Slytherin House, so please excuse me."

Snape's refusal did not exceed Li Zu's expectations at all.

"I can give you a price that satisfies you."

"Sorry, I'm not short of money." Snape still refused, his expression calm and calm: "If nothing else, you should leave, Professor Lee." ”

After weighing it again and again in his heart, Li Zu did not rashly choose to do it: "Maybe where can I buy the potion you made with my own hands?" ”

Without another refusal, Snape looked up at Li Zu.

As a potions master, even if his daily task is to teach young wizards how to make potions, he will occasionally make things that are not only stored on office shelves, but more likely sold to some corner of the wizarding world.

"What do you need?" Snape asked instead.

Li Zu suddenly had a guess in his heart: "Could it be that someone said something to him?" Voldemort, or Dumbledore? Magic is weird enough to be unguarded against. ”

But he said, "A potion that can resist the spell a little, and I have little defenses in this regard." ”

"A talisman charm can be solved" Snape gave Li Zu a strange look, if Li Zu hadn't known that he was Dumbledore's most trusted person, he might have been deceived by the other party's acting skills.

Snape said, "I can help you refine some with blackroots, curses, or anti-spells, but these are only basics, and if you are cursed by some kind, specific potions will be useful." ”

Is this a vague mention of Li Zu's curse from the witch, and told him that he doesn't need to worry too much?

"I'll give you a price you're happy with, Professor Snape."

Li Zu turned around and walked out of the office, and as he closed the door casually, he was also speculating in his heart that maybe Snape felt the idea of doing something, so he suddenly chose to "compromise".

In any case, he will soon get the potions from the Potions Master himself, and as for the compound decoction, elixir, blood-making potion, etc., he can buy them the next time he goes to Diagon Alley, or Tumbledown Alley.

"Or just grab it?" Li Zu was a little worried about his old profession in his heart, this was definitely a profitable business, and these wizards who were so frightened by a Voldemort that they didn't dare to move may have never experienced how desperate it was to be robbed by a planet-level villain.

"If this villain doesn't have zero resistance to magic."

Li Zu's luck was not bad today, Professor Felius Flitwick's Charms class time, and he didn't need to go to class, Professor Bubaji had already finished writing his new draft.

Walking on the way to the classroom, the students saw him greet him very respectfully, and the most eagerness among them must be the little wizards whose parents are Muggles, as well as the half-blood little wizards, they belong to the bottom of the chain of contempt in the wizarding world, so Muggle studies can be said to be a compulsory subject for them.

And today's little wizards are different, they wear a badge on their chests, on which is a simple spell, in short, at first it is Harry Potter's face, and then that face turns green, like some kind of viscous green liquid, converging into one sentence: Harry Potter, cheating!

The Ministry of Magic has just decided that students under the age of 17 cannot participate in the Triwizard Tournament, but Harry Potter is unexpectedly chosen to become the fourth person, which makes the arrogant little wizards who have always wanted to be glorified but unable to participate in it very jealous and angry.

A prank that swept almost the entire Slytherin house, as well as half of the other houses, was born.

Li Zu didn't see Harry, but there was one person who passed by him, Mad-Eye Moody!

The two sides stopped when they were only five paces away, and Moody's prosthetic eyes stared at Li Zu deadly, looking at him from top to bottom, from the wizard's robe to the dark green suit inside, trying to see through Li Zu completely, and finally Moody said, "The custom wizard robe is very good, Professor Li." ”

Li Zu also looked at the other party's broken face, and a piece of his nose disappeared, which was a trace left by him when he fought against black magic.

"Your eyes are also interesting," Li Zu responded.

Both of them clearly know that they have grasped each other's handle and understand each other's details.

Moody took out a bottle from his arms, poured two sips into his mouth, and then smiled weirdly at Li Zu twice, and the two staggered by.

Maybe Moody had already decided in his heart that Dumbledore had found a Muggle to come to Hogwarts just to spread suspicion and make Voldemort dare not move, but how did he know that Li Zu in front of him could extinguish the flames of the fire dragon with just one breath?

Even Voldemort is just a good character in Li Zu's eyes, and the "Moody" under him, of course, is not even a small role on the stage, and he still hasn't forgotten the reason why he stayed at Hogwarts.

Charms lesson,

Professor Flitwick had a lot of experience teaching Charms, but no matter how clever a professor was, he would never allow a Muggle to wield a magic wand before using a spell.

Chanting spells was definitely not a good errand, and it was a group of young wizards with very non-standard pronunciation, so the whole class, except for the beginning when Professor Flitwick explained the spells and demonstrated a few spells, there was only the sound of flies flying in the room.

……

Harry Potter sits by the lake,

The whole of Hogwarts thought he was cheating for the sake of showmanship, but Harry knew very well that he hadn't signed up for the Triwizard Tournament at all, not to mention that he wasn't even seventeen years old.

He just wanted to finish school in peace, nothing more.

But now it's a mess, Hermione hasn't spoken to them for a long time because of the fact that they fed Hagrid the truth potion before, and Ron didn't listen to Harry's explanation because of Harry's "cheating", and the former Iron Triangle is now a stranger.

"Harry, so you're here," came the voice.

Harry turned his head and saw that it was his roommate, Seamus Finigan.

"Seamus, is there anything to do with me?"

"Well, I mean, Hagrid is looking for you," said Seamus Finney, "and he says he has something very important to tell you. ”

Hagrid ......

Speaking of Hagrid, Harry's guide to the wizarding world, he felt infinite guilt in his heart, just as Hermione said, they actually fed Hagrid the elixir!

"Okay, I got it."

When it got dark, Harry found Hagrid, and he found that there was another person standing there, the tall Madame Maxime, who was like a big tree standing in the woods, and in Harry's opinion, not much different from her surroundings.

"Haha, Harry, you're here!"

Hagrid carried a lamp, the flame of which flickered in the brass lantern, and he lowered his height as a giant, leaning into Harry's ear and whispering, "I have something for you to see." ”

Led by Hagrid, Harry and Madame Maxime walked deep into the forest, breaking through the messy barricades, and walked for about half an hour, when they suddenly heard "Roar!!" Harry was startled, he didn't know what was happening, but Madame Maxim suddenly covered her mouth: "Oh my God! ”

She seemed to have guessed something.

Further on, scorching flames swept over the trio's heads.

Hagrid reached out and pressed down the grass beside Harry, allowing the distant scene to appear in front of Harry's eyes.

There are four cages in total, and inside are angry and fire-breathing fire dragons!

Several wizards were constantly using spells to try to control and appease the dragon, but the dragon spewed even more terrifying flames.

"Look at that tree bee, he's really spirited~" Hagrid exclaimed in amazement.

Harry was already standing dumbfounded, unresponsive.

It wasn't the first time he'd seen a dragon, Hagrid had raised a dragon before, but it was only the size of a hand, and now it was facing a ferocious behemoth! Harry's gaze immediately turned to Hagrid, who nodded with an inquiring look, "That's right, that's what your first game was about. ”

"Competition...... And dragons? Harry suddenly felt a jolt and his scalp tingled.

Although Hagrid is the hunting groundmaster of Hogwarts, he can't bring anyone in, let alone bring the contestants, which is cheating, but Hagrid has long been unconcerned about these small things.

"Maybe it's time for you to go back and think about what to do." Hagrid said.

"Thank you, Hagrid," Madame Maxim looked grateful.

After leaving the deep forest, Hagrid looked at Harry, who was bowed and silent, and said, "What's wrong Harry?" How to deal with a fire dragon in a headache? ”

Harry looked up at Hagrid's smiling face in the candlelight, and he wanted to ask why Hagrid could still laugh, it was a fire dragon! As soon as he was touched by the flames spit out by the fire dragon, he would surely immediately turn into charcoal.

"Don't worry, I've already made an appointment with Professor Li" Hagrid patted Harry on the shoulder and said, "He's an expert!" ”

"Who? Professor Lee? ”

Harry looked at Hagrid in confusion and blurted out the confusion in his mind, "Isn't he a Muggle?" ”

As soon as he finished speaking, Harry's expression became subtle.

Hagrid was even more surprised: "How do you know?" ”

"I ...... I ......" Harry hadn't figured out how to explain it.

However, Hagrid didn't ask, but nodded: "You're right, Professor Li is indeed a Muggle who can't use spells, but that doesn't prevent him from being a strong man." ”

Hagrid smiled mysteriously, "Professor Li, he's a strong man who has subdued a fire dragon!" ”

There was too much information, and Harry couldn't react a little, a guy who couldn't use spells actually surrendered a fire dragon? With what, is it a fist?

However, Hagrid's appearance looked normal, not like he had been under the Imperius Curse, and Harry chose to follow Hagrid to see it, despite his doubts.

They finally stopped in front of a lake at Hogwarts, where Professor Lee, who had changed his costume but still had a lazy temperament, sat by the lake, his owl standing on his shoulder.

"Professor Li, I've brought Harry here!" Hagrid shouted at Li Zu from a long distance.

Harry walked up to Li Zu and greeted him awkwardly, "Hello, Professor Li." ”

He once had the idea of using a truth potion on Li Zu, and now he also knew very well that Li Zu was a Muggle, so why should he find a Muggle to deal with the fire dragon? He didn't believe what Hagrid had said, Harry, who had just met the dragon, already thought it was too powerful to be invincible.

Maybe Professor Moody is more reliable!

Harry looked at Hagrid on the side, and after turning two steps, Hagrid hesitated and said, "Professor Li, you are very experienced in dealing with fire dragons, and Harry will deal with fire dragons tomorrow, so I want you to teach Harry." ”

Li Zu nodded happily: "Don't forget what you promised me." ”

With that, he waved his hand forward, and the owl on his shoulder flapped its wings and flew over to the surface of the lake.

With a "boom", the owl disappeared, and in its place, a large 20-foot-long creature appeared!

As soon as the fire dragon appeared, it roared in the sky, and the mist on the surface of the lake burned by the firelight boiled.

"Did he really, subdue a fire dragon and keep it with him all the time?" Harry looked at Li Zu and remembered for a moment, such as why whenever Li Zu's owl appeared, the other owls would hide away.

Another example is why Li Zu can't spell spells, but he can become a professor.

Because he has a dragon, a dragon that he surrenders without relying on a spell!
