[Comprehensive British and American] The world is malicious

"Time-Turner?" Nina stared at the Time-Turner lying in Avril Lavigne's palm in astonishment, the converter gave off a seductive light, "It looks a little different from the one in the book, can I take a closer look? "

"Of course." Avril didn't mind saying, when Nina looked at the converter carefully, Avril said happily: "It may be a newly developed converter, nine out of ten are like this, do you still remember Mrs. attitude? She keeps emphasizing that all converters are ruined and she's willing to sell us the only one.

Information on Knockturn Alley always circulated, and Mrs. Nitsch would not have said that if she had known that there was the latest converter. "

"How did you get it?"

"I took a little adventure, and the prize is it." Avril Lavigne said brightly, her fair cheeks flushed, she was obviously quite satisfied with her adventure.

"Nina, think about your six years at Hogwarts. Since the first year, you have been crazy about potions. Every Friday afternoon, you regularly report to the cellar under the Black Lake, no matter how black Professor Wilson is. To what extent, well, don't stare at me, Nina." Avril swallowed, for fear that Nina would throw the converter over.

"You need some spices for life." Avril moved forward and hugged Nina's arm, "A little adventure, this is what Gryffindor is good at, you have been stuck here for a summer vacation Alright, Nina." Avril Lavigne said in a drawn out tone.

Nina thought about it, and felt that she actually did a lot of things this summer vacation, and almost every one of them was related to the detective downstairs.Nina glanced at Avril Lavigne's longing face, thinking about Avril Lavigne's real purpose for inviting her here, Nina decided to keep silent.

If she said it, Avril Lavigne would probably have an awkward situation with her for two or three days, and then Sherlock would become more and more displeased.

In order to avoid such a situation, Nina turned to try to say seriously: "The effect of the time converter may be slightly different from what you imagined, Avril, maybe you should be a little more rational, we know nothing about this new converter .”

"You're here again." Avril couldn't help but rolled her eyes, and poked Nina's face with her hand, "Miss Roberts, your serious appearance is no longer deterrent. When you were writing your divination class homework, I It can be seen that you definitely have Gryffindor's nature in your bones... My dear, do you have the heart to let me do such a dangerous thing alone?"

"Gryffindor has always been brave and fearless, miss." Nina said after hearing the knock on the door, breaking away from Avril Lavigne's bear hug, Nina stood up, walked to the door, and opened the door.

"Excuse me, you...Miss Roberts' computer has been repaired." It was the young man from yesterday, and he passed on a gray overalls and stood outside the door with lowered eyes.

Nina took over the computer and thought of Sherlock's words yesterday, feeling a strange feeling in her heart. After quickly thanking the young man, just as she was about to close the door, a shrill siren sounded from downstairs.

Inspector Lestrade is here again.

Nina subconsciously thought that she was used to Lestrade coming here every now and then, and those who came to ask for help knocked on Mrs. Hudson's door in the middle of the night.

Nina thought about it, and when she looked up, she saw the young man's complexion was a little pale, and he was trembling slightly, "Sir, are you okay?"

"Yes... yes, I'm just not feeling well," the young man hurriedly replied, taking a few steps back, before he even had time to say goodbye, he hurried downstairs.

Nina frowned. The young man's behavior reminded her of the courier she received back then, which contained a bomb.

Nina felt that it was better for her to be cautious, so she cast a small spell on the computer. In fact, she wanted to do an insanity, but unfortunately, she couldn't do it.

If this continues, she may suffer from persecution paranoia. Nina put the notebook on the table against the wall.

Avril Lavigne was already lying by the window, looking curiously at the police car parked downstairs, she turned her head and said, "This must be the busiest place in London, if Mr. Holmes doesn't have that personality, I really want to go and see... At that time, I very much doubted whether he could tell the whole life of the other person just by looking at them.”

"What?" Nina felt that she had some auditory hallucinations, and Avril Lavigne's thoughts jumped too fast.

"Let's go to the crime scene and follow them, Nina." Avril suddenly suggested, "A simple invisibility magic."

"You should think about the seventh grade exam."

Nina's words hit Avril's sore spot, causing all of Avril's whimsical ideas to shrivel up like deflated balloons in an instant. Avril had a bitter face, and gave Nina a look.

Nina couldn't help holding Avril's shoulders and laughing.

Suddenly, Nina felt that the cell phone in her pocket was vibrating. She took a sneak peek at Avril Lavigne from the corner of her eye, to confirm that the other party hadn't noticed at all, and quietly pressed the text message. It was Sherlock's text message.

(Get rid of Miss Selinger, I need help, please come quickly. - SH)

"A text message from her boyfriend?" Avril Lavigne broke free from her frustration, quickly caught some gossips, and asked sharply, "Adrian from Ravenclaw? Anthony? Austin from Hufflepuff?... Could it be Grace?" Ranffindor?"

"No, Stephen's text message, he asked me when I would return to Hogwarts." Nina's face became hot, and she hurriedly stopped Avril from guessing, she would guess all the people she knew.

Nina put the phone back into her pocket, not to mention that Stephen did ask not long ago, although not this time.

Avril Lavigne thought of what Nina told her at the beginning of her summer vacation, and she was stunned for a few seconds before she came back to her senses, "Stephen is still studying ancient creatures... er... going around to solve the problem of ancient creatures running around?"

"Well, there are some future creatures." Nina added, feeling her heart choke immediately. Fortunately, except for that accident, she perfectly avoided those abnormal points that appeared in London from time to time.

"That is to say, after a certain point, we can reach the future?" Avril Lavigne asked brightly.

Nina shook her head. She didn't know anything about this. However, she thought that the reason why she was able to use magic without leaving spider webs was most likely related to passing through the abnormal point.

Avril was a little disappointed, looked at the converter in her hand again, put it into her pocket, and insisted: "Maybe we can really try, just a little bit, Nina, in Hogwarts, I can guarantee I just want to see it work wonders and will never do anything risky."

"...We can go to Hogwarts to continue the discussion, my dear, I will go out later." Nina glanced at the time, guessing that the Polyjuice Potion was about to expire.

After sending Avril away, after a while, Nina saw the police car still downstairs from the window, changed her clothes, and went downstairs.

It was Lestrade who opened the door, and Nina looked inside suspiciously. It was already ten o'clock in the morning, and Sherlock was still wearing pajamas, lying on his favorite sofa.

"I thought you were discussing the case." Nina said hesitantly. She really didn't expect such a scene in the house. At least Lestrade paid a special visit, not just to see Mr. Holmes still lingering on the sofa. look.

"Indeed," Lestrade said gloomily, twitching the muscles around his mouth slightly, and turned his head to look at Sherlock, who was facing the back of the sofa, "Are you really going to stop thinking about it, Sherlock? You know, this case is very serious. It's tricky, it's about Scotland Yard's reputation."

"So what!" Sherlock turned his head to look at Lestrade, and said without a pause: "Whether it is related to the reputation of the Queen of England, the reputation of the Prime Minister, or the reputation of the blacksmith, I don't care." , not to mention that this case is extremely simple, if you have not degenerated into a goldfish, Gavin, please think about it with your almost rusted head."

Sherlock sat up suddenly, and walked down from the sofa, "What I need is strange cases, not pediatric things. A random painting by Mrs. Roberts is more exciting than it."

Lestrade looked at Nina depressedly, and Nina twitched her lips in embarrassment, not knowing what to comfort Lestrade, Sherlock's words were too damaging, she shouldn't have come down at all.

Why is she coming down?

"But I can ask kind Miss Roberts to help." Sherlock continued.

"Miss Roberts?" Lestrade looked at Nina suspiciously. Although he thought Nina was just an ordinary student, at least he had been Sherlock's assistant for nearly a summer vacation.

"Sherlock was just joking, Inspector, I'm leaving tomorrow." Nina twitched the corners of her lips, and couldn't help but turn her head and stare at Sherlock. Sorry, she was just used to chatting with Avril before.

"However, what on earth is it that would touch Scotland Yard's reputation?"

The author has something to say: The author of hp really doesn’t know what to write ⊙﹏⊙

Maybe choose one of the three eras of Harry Potter, Pro-era, or Mysterious Man, or write directly according to this timeline (but it will advance Albus’s admission time)
