Chapter 115 Infiltrator

Saturday came in a flash. Although it was a pity that Lu Yunkai could not go to Hogsmeade with her (in fact, Snape had received the permission signature from Slughorn), Daphne still told Lu Yunkai that she would bring him many gifts, and then boarded the train to Hogsmeade with Millicent and Pansy.

Except for those who were punished to stay in school, most of the students above the third grade were on that train.

There were only two students who stayed behind for the same reason as Lu Yunkai, "no parent signature".

The other one...

"Yunkai, what are you going to do today?"

Another poor man who watched everyone leave at the school gate asked depressedly.

"Write a paper. Professor Snape assigned a paper on wound cleansing agents last night. It's good to finish it today." Lu Yunkai smiled and shook his head.

After returning to school this semester, Lu Yunkai originally thought that he would continue the Legilimency course from last semester, but he didn't expect that Snape didn't give him this opportunity.

"After the Chamber of Secrets incident last year, Professor Dumbledore thought that you should take a personality test before you can start studying. This matter has to wait until after OWLS. Although I think this is stupid, I can't help."

Snape secretly despised the headmaster.

But he also told Lu Yunkai openly that this paper assignment was his own idea.

And this is not the end, but just the beginning. This year he will assign Lu Yunkai a lot of homework, so that he has no chance to hang out with Harry.

"So this year even you think it's dangerous for me to play with Harry?"

Snape did not answer Lu Yunkai's question. But in fact, he didn't need to answer.

And when he heard that Lu Yunkai was going to write a paper on potions that should be learned in the sixth and seventh grades, Harry gave up the idea of ​​​​wanting to hang out with him on campus.

Anyway, because the Dementors have been hanging out outside the school this year, the temperature in Hogwarts is much lower than in previous years. It is not a good choice to play around in the school. The two simply said goodbye and went back to their dormitories.

Then, Lu Yunkai was disliked by the cat...

"Meow, why don't you go to Hogsmeade? Are you bored staying here?"

Chris, who was woken up by Lu Yunkai, glared at Lu Yunkai, jumped off his bed, and climbed onto Blaise's bed.

"Get down! If he finds cat hair on the bed, he will punish you again!" Lu Yunkai opened the potion book and casually reminded Chris.

He usually writes papers and makes potions in the lounge, but today most of the senior students are not here, and Lu Yunkai doesn't want to go out and be watched by a group of juniors.

Especially there is Astoria in here...

"It's like he can catch me." Chris climbed onto Blaise's soft pillow nonchalantly, curled up again, and continued to sleep.

Lu Yunkai shook his head gently, and then turned his attention to the book.

Write the paper!

But he just started, and suddenly, a strange sound came from the room.

Woo woo woo, like an alarm.

"Meow? What's wrong?" Chris, who was half asleep, looked up at Lu Yunkai, who was also confused.

"How should I know..." Lu Yunkai was also dizzy, "I'll go out and take a look, you continue to sleep!"

"Oh." Chris buried her head and continued to sleep.

Lu Yunkai packed up his thesis and walked out of the dormitory.

The lounge was in a mess, and a group of first and second-year students blocked the door, wanting to go out, but couldn't move.

"Everyone be quiet!!"

Looking around, there was no student above the third year, Lu Yunkai could only sigh softly and then shouted.

Of course, he did not forget to use a "loud voice" spell on himself with his wand.

As his voice stopped echoing in the lounge, almost everyone stopped making noise, turned their heads and looked at him.

"Get out of the way, I'll go see what's going on." Lu Yunkai said to the two first-year Slytherins crowded at the door.

"The door can't be opened."

Astoria, who was squeezed in the third position, took the lead in reporting to Lu Yunkai.

"Oh?" Lu Yunkai raised his eyebrows, "You go back to the dormitory first."

"But wasn't there an alarm just now?" A freshman blocking the door said timidly.

"There is no safer place in the whole Hogwarts than Slytherin's dormitory." Lu Yunkai smiled calmly, "If you don't believe me, you can ask your parents."

Lu Yunkai said this with confidence.

Just like Slytherin's dormitory is the most comfortable in Hogwarts...

When he came to the door, Lu Yunkai pondered for a while at the stone door that would open when someone approached from the inside, but was motionless at this time, and then drew out his wand.

"Shattered into pieces...Ah!!"

Before he could cast his spell, the stone door of the lounge suddenly opened.

Snape's figure appeared at the door.

Lu Yunkai's spell went straight to Snape.

But Snape outside the door easily waved his wand and knocked away the spell thrown by Lu Yunkai.

"What are you doing?" Snape looked at Lu Yunkai who was standing there in a daze and asked.

"Professor Snape, there was an alarm just now, and the door can't be opened..." The first-year student who was scolded by Lu Yunkai turned to Snape for help.

"Then stay in the dormitory honestly. There will be absolutely no danger in the Slytherin dormitory."

Snape said exactly the same words as Lu Yunkai.

At this moment, all the junior students looked at Lu Yunkai.

"Professor, what happened?" Lu Yunkai asked Snape.

"Just now, a guy who didn't know how to live or die wanted to break into the Slytherin lounge, but he didn't know the password." Snape shook his head, "Okay, let's go."

After saying that, he waved to the junior students.

"Professor, who is that person you are talking about?"

Seeing that most of the junior students had left, Lu Yunkai lowered his voice and asked Snape who was standing at the door.

He understood that Snape only wanted these students to go back to the dormitory, but did not intend to let them leave the lounge.

Why is this so? It must be because it is not suitable to go out now, that is to say, there may be something wrong outside...

"Why are you asking so many questions?" Snape glanced at Lu Yunkai coldly, "It has nothing to do with you."

"But..."

"Have you finished your paper?"

"...I will go back and continue writing."

Lu Yunkai gritted his teeth and turned back to the dormitory.

"Severus, did something unexpected happen in the school today?"

"Yes, Your Excellency the Principal."

In the blink of an eye, it was evening.

In the principal's office, Snape's face was very bad.

"Fortunately, it didn't cause too much turmoil." Dumbledore nodded, and there was no expression on his face.

"Your Excellency the Principal, I am very sure that it was Black who tried to break into the Slytherin common room. Why don't you believe it?"

"I have informed the Ministry of Magic about this matter. They said they will arrange someone to investigate..."

"Shouldn't we first drive out those who may bring Black into Hogwarts?" Snape interrupted Dumbledore.

"Severus, I believe in Remus as much as I believe in you." Dumbledore shook his head.

"Then what did you ask me to do?"

"I want you to ask Lu Yunkai where Chris went a month after the death of the basilisk last year."

"You can ask him yourself."

"He has never liked me. If I ask him, he won't tell me."

"Then I suggest you find a way to make him like you." Snape sneered, "I took a look at the wound cleansing agent paper he just gave me. I plan to help him revise it and recommend it to the Daily Prophet for publication, so he probably doesn't have time to do this kind of thing."

"Is that so? That's a pity."

Dumbledore didn't say much and watched Snape leave the office.

"Yunkai, I heard something happened today?"

In the Slytherin lounge, Malfoy asked Lu Yunkai, who was sitting there reading a book he didn't know what it was and eating the candy Daphne brought him back, with a frightened look on his face.

"Well, it seems that someone tried to break into the lounge and triggered the alarm. It's not a big deal."

"Are you sure?" Malfoy shook his head. "Before, Goyle also tried to sneak into the Gryffindor lounge. He answered the wrong password but didn't trigger any strange alarms!"

"After all, we are Slytherins! We have things that Gryffindor doesn't have. Isn't it normal?" Lu Yunkai said with a smile.

Malfoy was stunned.

Then he laughed.

"That's right. I heard from my father that the board of directors plans to replace a batch of sofas in the lounge this year, but it has not been finalized because they have not discussed whether to add massage spells to the sofas."

"Forget it! It's weird to sit on a sofa with a massage spell." Pansy tried to interrupt from the side.

Today in Hogsmeade, she successfully drove Goyle and Crabbe away from Malfoy for a while, which made her feel that "she is already Mrs. Malfoy."

"My father said so too." Malfoy gave Pansy a smile.

Pansy's face was smiling like a flower...

Lu Yunkai smiled and didn't join in the conversation between the two.

But he was not as relaxed as he looked.

He hurriedly wrote the paper during the day today. It was not because he thought he could finish the homework earlier and relax earlier, but because he wanted to finish the work quickly so that he could organize his things.

Although Snape didn't say it clearly, it was obvious that the person who wanted to enter the lounge was not an ordinary person.

Lu Yunkai guessed almost instantly that the person who triggered the alarm was probably Sirius Black.

How did that guy get into Hogwarts?

And more importantly, why did he try to enter the Slytherin lounge?

A Death Eater who could break through the layers of blockades and come here couldn't have known that today was Hogsmeade Travel Day. So why did he have to enter the lounge that was basically empty?

Was he really going to come in to find someone?
