In the dimly lit hallway of the castle, a group of professors hurried towards the basement. The professors were holding wands in their hands, all of which glowed slightly, but only illuminated a small area. The walls on both sides of the hallway are old portraits of Hogwarts wizards from all ages. The wizards are awakened by the sound of the professors' footsteps, shouting at them for not lighting their wands. But no one cares about them at the moment. Through the faint light of these wands, I could see that most of the professors were not good-looking, and they were all worried.

"Why do trolls show up in schools? As far as I know, there hasn't been a sign of trolls in the vicinity of Hogwarts for many years. It's anomalous. Professor McGonagall said in a puzzled voice.

"The first trolls disappeared two hundred years ago. If it really was a troll, I can't imagine how it got in. Professor Flitwick said.

"Apparently, someone put the trolls in." Hagrid said angrily.

"Why don't you see Professor Snape?" Ms. Sprout asked suddenly.

Everyone shook their heads, indicating that they hadn't seen Snape. Snape should have been there at this time, but he was gone, which made them a little suspicious.

"Well, let's think about how to deal with a troll who is roaming around the castle and maybe angry. We're focused on solving more important problems, aren't we? Dumbledore said at this point.

"I'm just curious, Headmaster, I think there's a story in there." Ms. Sprout continued.

The others did not speak again, each with their own thoughts, and the crowd hurried forward with their wands raised.

Li Quan didn't express a word, but he knew the most detailed things.

He knew that this was clearly a ghost directed and acted by Quirrell. He and Voldemort try to take the opportunity to get everyone's attention, and they then go in and steal the Philosopher's Stone. They failed, being stopped by Snape, who had slipped away in a hurry.

The true position of Snape, a loyal member of the Order of the Phoenix and Dumbledore's staunchest supporter, was not revealed until much later in the book. Snape has been silently guarding Harry Potter in his weird ways. This made him deeply misunderstood by everyone until his death.

Snape clearly knew a lot about trolls. Dumbledore interjected to cover for Snape, and the professors present were probably the only ones who knew the cause and effect to hear it. Everyone else is still in the dark.

When the professors hurried to the basement, they found that the trolls were not here.

Some professors looked nervous, and there was a troll running around the school, which was too dangerous. In case a student is going to be injured, or even ...... That's unimaginable.

"The trolls are gone." Hagrid's tall body crouched on the ground, and he seemed to have spotted something on the ground, pointing to a corridor urn and saying, "Go over there." ”

"Let's go." Dumbledore said without hesitation, following Hagrid briskly towards the hallway. He trusted Hagrid's judgment. When it comes to tracking magical creatures, there's no one here better than Hagrid.

The others followed in silence, the worry on their faces unabated. Only Li Quan was calm and calm, and seemed a little absent-minded.

Compared with this, Li Quan was more concerned about the traces of the black-haired boy.

Who is this man? Where did it come from? Could it be that there is also World of Warcraft in this world? That young man has been in contact with Warcraft, so he can call out the origin of the imp at once? Or......

He couldn't help but think of another possibility. Perhaps, that man is also a traverser.

Li Quan's eyes gradually widened, and the more he thought about it, the more he felt that it was very possible......

If he can travel to the world of Harry Potter through the system, why can't someone else travel in as well?

This seems to explain why the person knew about the imp, and why the other party ran away when they saw him. Perhaps, the other party didn't expect to be shocked to see things in World of Warcraft in the Harry Potter world?

"Could it be that person is really a traverser, just like me?" Li Quan thought, not only was he not worried, but he was also faintly excited. Did you really meet the same kind? Who is the other party? How? If the other party is really a traverser, can the other party cooperate with you? Does the other party also have a system in their body?

I'll have to ask the system about it later. Li Quan thought. If you don't understand this, I guess you won't be able to sleep for many days.

On the way, Hagrid lost track of the trolls, and as a last resort, the professors split into three groups and searched in three directions. Li Quan offered to go all the way with Dumbledore and Professor McGonagall. Halfway through, they met Snape, who had arrived in a hurry.

"Severus, you've come at the right time, we'll need your help in the face of the trolls." Dumbledore said.

"I'm sorry, Headmaster, for a little delay." Snape said quietly.

Li Quan's gaze swept over one of Snape's legs, intentionally or unintentionally. He didn't see anything, but he knew that Snape had injured one of his legs.

Snape immediately blocked Li Quan's vision with his robe, and asked Li Quan, "What are you looking at?" ”

Li Quan shrugged his shoulders and looked away nonchalantly.

Snape gave Li Quan a deep look and snorted.

When Dumbledore, Professor McGonagall, Li Quan, and Snape finally arrived at the scene, saw the troll, and saw another scene in front of their eyes, not only Dumbledore, Professor McGonagall, and Snape were all shocked, but even Li Quan was also shocked.

Compared with the others, Li Quan's face was extremely strange, and he looked at the scene in front of him in disbelief.

The troll is down. This did not surprise him in the slightest. According to the plot, Harry, Ron, and Hermione fought wits and courage to deal with the trolls, and it actually went according to the plot. However, in addition to Harry, there was one more person outside the script.

This is the girls' bathroom, which has been destroyed by trolls, with debris of houses everywhere and water all over the floor. At this moment, in addition to a huge and ugly green-skinned monster about five meters tall, there was also a person wearing a Hogwarts student uniform. Li Quan could see clearly at a glance that it was the black-haired boy from before!

Li Quan hurriedly walked up first, he squatted down and probed the other party's snort, and his face became even more strange.

There is no breath left. Actually dead!?

Dumbledore and Professor McGonagall also walked up quickly, their faces very ugly when they confirmed that the student lying on the ground was dead. Even Snape, who was standing silently next to him, looked solemn.

The three of them were shocked by the death of a student, but Li Quan was shocked that the black-haired boy he was looking for, who he suspected was also a traverser, actually ...... Just dead?

What the hell is going on!?

The dignified traverser is actually dead...... This made him can't help but overturn his previous speculation. How did the traverser die so neatly? From his point of view, this unlucky guy hung up almost as soon as he appeared, and he received the lunch box in minutes, how could he have the style of a crosser. It's ridiculous that he just wondered if he was looking for the other party to cooperate.

There is also a question, why is this person here?

He looked at Harry, Ron, and Hermione. The three little wizards were standing in the corner, their bodies were very embarrassed, and the faces of the three of them were pale, as if they were still apprehensive about the thrilling battle that had just happened.

"What the hell is going on, Harry?" Dumbledore stepped forward, grabbed Harry's wrist, and asked in a serious tone.

Questioned, Harry stumbled to explain his previous experience truthfully. Except for the presence of more dead people who shouldn't have appeared, the rest of the story is basically the same as the original plot. Dumbledore and the others looked at each other after hearing this, and they all felt that this was too strange.

After Li Quan heard this, he couldn't help but ask out loud, "Harry, do you know him?" He gestured to the dead black-haired teenager. He could only hope for a little news from Harry now.

Unfortunately, Harry quickly shook his head and said, "I'm sorry, Professor, I don't know him. Ron and I arrived first, and when we saw Hermione being attacked by a monster, we tried to distract the monster. After a while, the classmate arrived, and he was so brave that he barely thought about fighting the monster. But unfortunately...... In the blink of an eye, he was killed by this monster......" After Harry finished speaking, Ron and Hermione both nodded hurriedly to confirm Harry's words.

"Hand-to-hand combat with trolls?" Li Quan's face became even more eccentric. What the hell is this man thinking! "Have you seen him before, and what academy is he from?" He groaned for a moment, then asked.

After the three of them looked at each other, they shook their heads together, all of them saying that they didn't know each other and had never seen this classmate. Li Quan looked at the professors present again, and from the confused looks on their faces, they were also very puzzled, all thinking about who this was, even they had never seen this person. Although there are many students at Hogwarts, there are more than 1,000 people, but at least they are all familiar. But this person, they have no impression at all.

Li Quan flipped through the Hogwarts uniform on the dead boy, revealing the house badge on the other party's chest, with a snake embroidered on it.

"Look at this emblem, it's a Slytherin student." Li Quan immediately looked at Snape.

Snape shook his head in denial: "I've never met this student. "Listening to his tone doesn't feel like a lie.

Everyone was silent, including Dumbledore.

Now there are many suspicions. A student died, but no one knew him. He was wearing a Slytherin house costume, but even the Slytherin dean said that he had no impression of him.

The situation is confusing, but anyway, the dead man is dead, which is the worst outcome, the last thing the professors want.

Li Quan actually wanted to tell them that the person who died was probably not a Hogwarts student, or even a person from this world. But he couldn't help but say nothing. It's impossible to say such a thing. He could only keep the biggest confusion in his heart and leave it for slow explanation.

Snape said that the consequences of the incident were very serious, and as a warning, the school should severely punish the three young wizards who caused trouble: Harry, Ron, and Hermione.

So back to the original plot, Snape thinks Harry should be punished severely, but Professor McGonagall thinks that Harry and the three of them are commendable and worthy of praise for their courage in fighting trolls. Li Quan, of course, was helping to say good things, and agreed with Professor McGonagall's opinion. Dumbledore remained neutral and did not express an opinion.

In the end, Professor McGonagall announced the results, still staying true to the plot. Gryffindor House had points deducted for the recklessness of the three Harry. And then because of their courage and outwitting the trolls, the score was added back. This upset Snape, but didn't say anything.

Dumbledore told the three of Harry to go back to rest first. Soon, several other professors who were separated also arrived. When the professors saw the troll lying on the ground and the corpse of a student, they were all shocked.

Quirrell also appeared. He behaved cowardly and seemed scared at the sight of the troll. Only Li Quan knows that this guy is purely an actor.

At this moment, Dumbledore waved his wand, attracting everyone's ideas. "Well, it's clear to everyone, unfortunately one of the cadets died in the school, and as the headmaster of Hogwarts, I think I have to take responsibility for it. The identity of the student has not been ascertained so far, which is suspicious, but there is no denying that something is wrong at the school, a dark creature has broken into the school, and I want to find out why. He turned to Snape, "Severus, I'll leave this matter to you." At least on the surface, this cadet is a student at your academy. I guess, you don't have an opinion, right? ”

"Of course, I'll find out as soon as I can." Snape nodded lightly.

"Alright, let's go back to everyone else." Dumbledore said. Everyone whispered and left. Li Quan also left alone. Dumbledore glanced at Li Quan with great meaning when he turned around, but Li Quan was so confused that he didn't notice it.

After returning to his residence, Li Quan lay on the bed, closed his eyes, and sorted out all these things tonight.

He first took the imp to the Halloween Eve party, and met a black-haired boy who called out the origin of the imp and knew about the World of Warcraft and the Warlock, who looked like an Oriental. Because the other party speaks English, it is impossible to judge whether it is Chinese or not.

Then the boy seemed to be afraid of him, turned and ran.

He never found him since. But I saw it again in the girl's bathroom where the troll appeared. When we saw him again, he was dead......

All these strange things came so quickly that he was a little overwhelmed.

He had guessed that this person was probably also a traveler from another world, but when he saw the corpse of the other person, he couldn't help but doubt this inference.

Just now, he carefully examined the other person's body, and even searched the person's body several times while the other professors were not paying attention, but found nothing. There was nothing on the other side, not even the most basic wand of a wizard. Aside from wearing a school uniform robe with a Slytherin insignia on it, there is nothing else to prove his identity.

Who is this man? Why do you know about Imps and World of Warcraft? Why did you run away when you saw him? Why did it suddenly appear in the place where Harry was fighting the trolls? According to Harry, this man seems to have taken the initiative to fight the troll in close combat, and then was shot to death by the troll at once, did he deliberately seek death?

The more I think about it, the more confused I become, and the more I think about it, the more I feel that it doesn't make sense. Li Quan lay on the bed tossing and turning, looking strange, and he found that he knew nothing about this matter. The only thing he knew was that he wouldn't be able to sleep tonight.
