On Halloween night, all the professors and students celebrate the arrival of the holiday in the auditorium.

But a loud bang broke the harmonious atmosphere.

"Trolls! There are trolls in the school! You should know......" Quirrell fell to the ground as if he had been terrified.

Watching Quirrell's clumsy performance, Li Yi shook his head, took a pudding from the table, and then got up to leave.

Just as he was about to reach the door, the entire auditorium seemed to suddenly react.

Dumbledore began to speak out to comfort everyone, and then asked the prefects to return to the dormitory with the frightened students.

Trolls are not something that a few young wizards who have not yet graduated can solve.

Looking at the departing Li Yi, Dumbledore didn't say anything, he knew the strength of this child.

In just over a month, while listening to the story, the magic in his body continued to grow, and now, the magic power in his body alone is not inferior to that of the professors. If it weren't for the fact that Li Yi and Voldemort were fundamentally different, Dumbledore would have said that he would have eliminated this future threat.

Now that he saw that Li Yi was really ready to save Hermione, it could be regarded as a verification of his guess.

Coming to the basement, Li Yi saw the figure of the troll, which was walking towards the girls' toilet.

"Tsk, this is the time for heroes to save beauty." Li Yi thought about it, and then flashed in directly.

Hermione felt terrible, she was already a little depressed today because she was not understood, and now she suddenly saw a monster with a hideous face and a height of three or four meters appear in front of her.

But the next moment, she felt a little safe.

Because she heard Li Yi's voice.

At this time, the troll with a low IQ also heard Li Yi shouting for Hermione, and it turned to face Li Yi.

Li Yi used expressions and gestures to suggest that Hermione cautiously walked outside the girls' bathroom, Hermione said that she understood, but just as the troll and Li Yi confronted her, Hermione was about to go around to the door for a while to answer Li Yi, when they heard the sound of the door being locked.

Hermione ran to Li Yi's side: "What should I do?" The door was locked. ”

"Then let's fight directly, don't worry, I have a way. The weak point of the trolls is the back of the head, which is where they are most vulnerable. ”

"And how are we going to fight?"

It wasn't a specific tactic that answered her, but a spell, the same spell she had thought was useless before—"Random Fusion Spell!" ”

Li Yi directly connected the troll's legs to the floor, and it was a stronger connection than glue, as if the troll was really one with the plank.

Hermione was a little surprised, she didn't expect this spell to be used like this, but after seeing Li Yi's fighting style, she quickly learned a trick - "Hard as iron!" ”

Her target was the floor under the troll's feet, and with the power of the troll, maybe it could directly destroy the floor, but now it is several times more difficult to destroy it out of thin air.

At this time, the door to the toilet was also opened, and it was Harry and Ron who broke in. Obviously, although they have some bear children's problems, relatively speaking, they still know their mistakes and can change them.

They also saw the struggling troll, looked at each other, and then suddenly shouted at Li Yi and Hermione, "Sige, Hermione, you come out quickly, we lock it inside." ”

But at this moment, the troll broke free from the shackles under the influence of some unknown force.

Li Yi sensed this power, it was some kind of power from the castle.

"Damn, I know." Li Yi scolded secretly, directly picked up Hermione and ran out, but Harry and Ron, who were outside, didn't know what was wrong and suddenly ran in screaming again.

"What's wrong? What are you doing? Hermione asked.

"Outside, there's a ...... outside" Harry and Ron's voices trembled a little, and it was good that the two eleven-year-old boys suddenly saw such a monster and were not so frightened that they sat on the ground.

"Come in, go get rid of the one inside! The new guy outside is handed over to me. Li Yi gritted his teeth, rushed directly to the door, pulled the two overly frightened little children into the bathroom, and then prepared to face the new monster outside.

Hermione followed him and ran out of the place.

"What are we supposed to do?" Harry shouted.

The only answer to him was Hermione's "Levitation Charm!" ”

Turning around, Harry and Ron looked at the troll that was frozen in place, motionless, and looked at each other: "Levitation Charm? "They don't know why the levitation charm helps them hit the trolls.

After trying for a long time, the troll finally found that he couldn't even move, and at this time he saw two little ones arguing, so he swung the big wooden stick in his hand and smashed them at them.

Luckily, they were far away, and the troll's sticks couldn't hit them.

"Yuga Dim Leviosa!" Harry had just been taken aback, and then thought of Hermione's suggestion. Now he subconsciously used the levitation spell he had just learned.

Then they saw the stick suddenly come out of the troll's hand.

"What now?" Harry asked in a loud voice as he controlled the stick, to Ron, who was standing on the sidelines.

"Smash it! Trolls have weaknesses...... It seems to be the back of the head! Right...... It's the back of the head! Harry! Control that stick and smash it! Ron finally remembered one of Professor Quirrell's things that were so useful.

Harry hurriedly controlled the wooden stick to float high in the air of the troll, and now the troll was still fixed on the ground, so he was directly knocked out by Harry's stick.

"Quick! There's one more out there. We're going to help! After seeing the troll pass out, they hurriedly opened the bathroom door, wanting to help Li Yi and Hermione.

But when they followed the sound of the troll's roar to the corridor, they saw the troll that had been beaten and fell to the ground, and Li Yi next to him was chatting with Hermione.

At this time, Professor McGonagall, who had been detoured by Dumbledore, finally arrived here.

Looking at the four freshmen on the field, her face was extremely serious: "What the hell are you guys playing, why don't you go back to the dormitory obediently?" ”

"Professor, Hermione was just crying in the women's bathroom, and we rushed over to inform her." Li Yi explained to Professor McGonagall.

"And you, Sige. I know your magic is strong, but an adult wizard can't necessarily subdue a troll......" McGonagall looked around and saw that there was only one troll, "What about the other troll?" Have you seen that? ”

"Professor, the other one is in the bathroom, and he's been knocked unconscious...... Harry whispered about the results of his and Ron's fight.
