Harry stood in front of Li Quan and looked at him, and asked a little crampedly, "Professor, what are you looking for me?" ”

"Harry, don't be nervous. That's right, I have something for you. Li Quan sat behind the experimental table and said mildly. He smiled faintly, flipped his palm lightly, took out a few bottles of red potion from the storage space, and placed them on the test table.

Harry blinked vigorously, and he was amazed by the magical sight. "Give it to me? But...... Professor, what is it? Harry asked.

"It's called a primary healing potion. Its effect is amazing and can help you heal very serious injuries. Remember, as long as there's a breath left, the way to use it is to drink it straight. Li Quan explained with a smile.

The bottles he pulled out were Azeroth's primary healing potion. It's what he's left of before. Now that he himself was using upgraded secondary healing potions, the effect was better than the primary one, and these were useless.

"Why are you giving me this?" Harry asked, surprised.

"For self-defense, of course. You'll use it, Harry, trust me. Li Quan smiled and reached up and patted Harry's shoulder, pushing the bottles of potion to Harry, "Take it, put it away, don't be seen by others." It's a secret between the two of us. He winked at Harry.

Harry laughed. "Thank you, Professor Li." Harry had already labeled Li Quan as a good guy in his heart, and no one cared so much about him except for Hagrid and Dumbledore, as well as Ron and Hermione. Now it seems like there's one more.

Li Quan smiled and nodded. "Alright, let's go. Don't keep your friends waiting. Ron and Hermione waited at the door of the classroom with curious faces on their faces.

Harry nodded. He carefully tucked the potion into his arms. Then he turned and walked out of the classroom, and went downstairs with Ron.

In the classroom, Li Quan's smile gradually retracted, and he sighed softly.

This is his easy way of approaching Harry Potter. Although he didn't need Harry's help for a while, it was always right for the time-traveler to have a good relationship with the protagonist of this world. Now that I've got a good relationship with Harry, maybe it will work in the future.

Harry, Ron, and Hermione walked out of the Potions classroom and left the tower together up the spiral staircase. In the small garden of the castle, Harry happily said to Ron, "Ron, I love Potions class!" The class was more interesting than I expected. ”

"Me too, Harry. The class was amazing! Ron agreed.

"Obviously, Professor Lee is a very knowledgeable Potions master, and his lectures are so good that I can't wait for next week's class." Hermione said with a look of intoxication and wistfulness.

Harry and Ron looked at each other, not knowing what to say.

Unlike in the original books, Harry and the three of them enjoyed Li Quan's Potions class. In the original books, Potions class was Harry's nightmare, Harry's least favorite class. Just because the Potions teacher was Snape. Today, it's the other way around.

Li Quan was in the classroom for a while, and then left the classroom and returned to his own residence.

He wasn't just going to give Potions class to first grade, but to all seven grade students. Fortunately, there is only one class a day, and at most there are only two classes. It's still what he's best at, and overall, the experience is pretty good.

The only inconvenient thing is that he needs to take a mouthful of age-enhancing products frequently. Then he will go back to his place. He thought he should follow Moody's example and carry a small bottle with him.

The system has issued him a new mission, saying that it has sensed the presence of a powerful energy source in this building and asked him to get it. The reward is 2000 contribution points. He knew that the system was referring to the Philosopher's Stone. According to the original plan, it was not impossible to obtain the Philosopher's Stone, and the breakthrough was on Harry.

Time flies.

Li Quan spent the autumn at Hogwarts. He taught different grades every day, and in his spare time he would go to Lady Sprout, a professor of herbology, to discuss the world's amazing plants, or to Mrs. Hooch, who taught flying lessons, to learn how to use a broomstick, or to Hagrid's hut to hang out with Hagrid. The time soon came to the end of autumn, and Halloween arrived.

Halloween is celebrated on November 1 every year and is a traditional holiday in the West, also known as the Western Ghost Festival.

Westerners use this day to praise autumn, sacrifice the souls of the dead, and pray for peace. On this day, Westerners hold festival parades and play the role of ghosts to hold celebrations.

And Halloween Eve, as the name suggests, is the night before Halloween.

Halloween Eve is more lively than Halloween. On Halloween Eve, adults light jack-o-lanterns and set up a sumptuous dinner. Children will dress up as all kinds of cute ghosts and knock on doors from house to house, asking for candy and trick-or-treating if they don't give candy.

On Halloween's Eve, Hogwarts prepared a sumptuous feast for all the students and teachers of the school. Students have joined in the entertainment of dressing up ghosts, walking around the campus, all kinds of strange costumes are overwhelming, quite lively. After Li Quan saw it, his heart was itchy and he decided to pretend to do something.

Harry takes on the role of a postman, dressed in a comical Muggle costume that attracts the attention of many young wizards. Ron is played as a zombie, which he got from his quirky twin brother. In comparison, Hermione was more normal, she just dressed herself up a lot more mature, looking like a grown witch.

When the three of them bumped into Li Quan in the corridor of the castle, all three were stunned.

Li Quan walked all the way, and all the students along the way looked at him with dumbfounded expressions, and the little thing that followed him at his feet.

Li Quan's outfit is nothing, just a black tuxedo, and he is wielding a domineering whip in his hand, which is the whip of the dog king Haka. The main thing that caught his eye was a little imp at his feet, yes, a demonic imp from Azeroth.

Bringing a little ghost to the Halloween party is the most ingenious creative costume Li Quan can think of. Tonight, he doesn't need to scruple too much, he can summon the little ghost in a grand manner. After returning to Stormwind from the Desert of Tanaris, he immediately found other warlocks to buy a large number of soul fragments, enough to use for the next century.

Harry looked at the flaming imp on his green body in surprise, and he asked Li Quan, "Professor Li, what is this?" Looks like a house-elf. ”

Before Li Quan could speak, the little ghost was no longer happy to hear it, and it shouted loudly, saying a demonic language: "You are the house-elf!" Your whole family is house-elves! ”

Hermione asked in surprise, "Professor, what is it talking about?" ”

Li Quan sweated for a moment, smiled and said, "It said hello, it's a pleasure to meet you." ”

Hermione smiled sweetly when she heard this, and she crouched down and leaned in amicably to the imp and said, "I'm glad to meet you too!" ”

The little ghost scolded: "Die! Stinky kids! ”

Li Quan smashed his fist on the door of the little ghost's head, smashing the little ghost to a stumbling block, and he introduced with a smile: "This thing is called a little ghost, and it is not the same as a house elf, they are completely different creatures. ”

"Cool!" Ron said with an envious expression.

The other students around were also talking and laughing, and everyone was amazed that it was the first time they had heard and seen this creature.

Li Quan smiled slightly, and was about to speak, but an even more surprised voice next to him said something that made Li Quan stunned: "Little ghost? Warcraft? Warlock? ”

Li Quan's eyes widened immediately!

He immediately looked at the source of the sound, and saw a young man with black hair and black eyes standing in the group of students, dressed in a Hogwarts uniform, about sixteen or seventeen years old. The young man was looking at the little ghost with a shocked expression, and Li Quan was also looking at the young man in shock.

Li Quan and the boy glanced at each other.

He was about to ask how the other party knew, but the black-haired boy glanced at him hurriedly, then immediately pushed away the person behind him and hurriedly squeezed into the crowd. Li Quan stood on tiptoe and tried to look for it again, but there was still a figure of the other party.

Li Quan was stunned for a long time, he was puzzled in his heart, how could this person know the true origin of the little ghost? And the World of Warcraft? Could it be that World of Warcraft also exists in this world?

"Professor, what is World of Warcraft?" Harry asked. Ron and Hermione were also at a loss. They obviously don't know anything about World of Warcraft.

"What the hell is going on? Could it be that I misheard it just now? Not quite like ...... Judging by the teenager's reaction, the other party must know something that I didn't know. No, we have to find the boy again. Li Quan thought.

He was about to explain when a loud voice came from behind them. Dumbledore walked into the crowd at some point, and when he saw the imp, Dumbledore was also surprised and said, "Oh, strange creatures! It is clear that it comes from the mysterious East, and I have never seen such a creature. He looked up at Li Quan and asked in a low voice, "Is it safe enough?" Dumbledore had obviously seen more than Harry, and he had seen that imps were creatures capable of fighting.

"Of course, it won't mess with anyone without my orders. I promise. Li Quan said with a smile.

"That's good." Dumbledore walked to the banquet hall and beckoned to Li Quan with a smile: "Come on, Professor Li, the party is about to begin." I don't want to miss tonight's feast, I heard that the house-elves made creamy muffins. ”

Li Quan nodded, and could only store the doubts in his stomach first. He decided that he would go in later and find the black-haired boy.

Harry and the others poured into the ballroom along with the other onlookers.

After taking his seat, Li Quan kept scanning the audience, trying to find the black-haired boy.

But unfortunately, thousands of students gathered at the long tables of the four colleges at the scene, and trying to find a new face among so many people is really like looking for a needle in a haystack. After looking for a long time, he didn't see the boy just now.

As Dumbledore got up to announce the start of the feast, the hall was filled with joy. Giant jack-o-lanterns replaced floating candles, becoming the most eye-catching light source in the hall floating overhead. The enchanted dome above the hall was thundering, and the lightning was continuous, giving the hall a bit of an eerie atmosphere.

The theme of tonight's banquet was candy, and a long table full of desserts was laid out in front of the students. There were also more than a dozen brightly colored desserts on the table in front of Li Quan, but he was like chewing wax and didn't taste anything.

Originally, he thought it was just an ordinary Halloween, and he came to join in the fun, but he didn't expect to encounter such a strange thing. But the boy couldn't find it. What a hell!

Halfway through the banquet, Li Quan knew that the plot was about to begin. Halloween Eve is a major event in Harry Potter's first school year and is an important part of the plot.

In the banquet hall, the students were chatting with food as their company, when suddenly, the door of the banquet hall was slammed open, and a man with a thick turban broke in in a panic, it was Professor Quirrell, who was screaming hoarsely, as if fleeing something: "Troll! Trolls! In the basement! There are trolls in the basement! ”

The atmosphere in the banquet hall seemed to be choked by the throat all of a sudden, and the audience was silent.

Both Dumbledore and Professor McGonagall stood up in surprise. Quirrell ran to the middle of the hall and said "I think I should have informed you...... and he simply fainted.

In the banquet hall, after a moment of silence, the students suddenly became a mess. The students screamed in horror that there were trolls in the school! A professor has fallen! It's scary......

Seeing that the situation was about to get out of hand, Dumbledore stood up in time. "Quiet—" His voice resounded through the ballroom. The students immediately fell silent, and they all turned their heads to look at Dumbledore.

Dumbledore's calm appearance calmed everyone present. I only heard him say lightly: "Please don't panic. Now, the prefects are taking the students of their houses back to their dormitories. The teachers went to the basement with me. ”

The prefects of each academy immediately led the students out of the banquet hall in an orderly manner, and the banquet had been forced to be suspended.

Li Quan saw Snape sneak out of the side door as well. Everything is going according to the script. Except for the dark-haired boy who was missing, he still couldn't find the man in the crowd when the students left.

Madam Pomfrey, the school doctor, went up to check on Quirrell as he fell to the ground, then looked up and said to Dumbledore, "It's okay, he just passed out." ”

Dumbledore nodded, and he said to the surrounding staff, "Come with me to the basement." ”

Li Quan followed Dumbledore and the others and hurriedly walked all the way to the basement.

He knew that Harry Potter and Ron were probably out of the student ranks, and instead of going back to the dormitory, they went to Hermione. According to the plot, Hermione was annoyed by the two before, and she would be hiding in the girls' bathroom and crying. She happened to encounter a troll in the women's restroom.

This troll is not another troll, not a race of trolls from the Azeroth tribe, but a stupid humanoid creature of gigantic size, a type of dark creature.

Harry and the three would then engage in a battle of wits with the trolls, but there was no danger. Li Quan's whole mind was still on the black-haired boy who appeared inexplicably and disappeared in a hurry at the moment. He couldn't figure it out.

"What the hell ......"
