a certain scientific harry potter

Otherwise, he wouldn't have immediately made plans to snatch Lucius' wand after realizing that his routine had failed.

Forced by Salazar to fuse Voldemort's soul fragments, Harry also got some memories of Voldemort's diary Horcruxes at the same time, so in his analysis, the latent fingerprints left on the diary should not be destroyed. Treat it like a stain remover.

The essence of magic is a kind of spiritual power. What is known for sure exists, and what is not known is likely to be regarded as nothing.

Therefore, for Voldemort and his Horcruxes, this kind of sweat latent fingerprints that will stick to them even if they are washed cleanly, are not considered pollution or destruction.

Therefore, even if this former Horcrux has a certain degree of self-cleaning function, it can absorb or remove the stains, but after all, it cannot erase the fingerprints that "do not exist" for it.

In many cases, magic is indeed more powerful and magical than science, but this does not mean that this power is completely without loopholes.

And Harry happens to be able to use science to exploit the loopholes in magic, and successfully find out the hidden clues!

(ps Simple science popularizes the principle of silver nitrate solution to test fingerprints, which is actually the chemical equation of middle school: NaCl+AgNO3=NaNO3+AgCl↓;

Sweat latent fingerprints contain sodium chloride, which reacts with silver nitrate to form insoluble white precipitated silver chloride; silver chloride is unstable and will gradually decompose under light conditions, eventually becoming brown-black fingerprints that can develop color.

In addition, the question of whether fingerprints can be stained on Horcruxes, in fact, you don't need to be too entangled, the purpose of writing this paragraph is actually to express the point of view that 'science and magic have their own loopholes'.

With the character design of the protagonist, it is inevitable that he will use scientific means to exploit the loopholes of magic, but this does not mean that the protagonist denies the fact that magic is more convenient than science, above~)

Chapter 190 The idea of ​​the detective agency was proposed by the little fan

"Amazing! It's unbelievable that I'm taking photos of Harry's fingerprints?!"

Colin pressed the shutter continuously according to Harry's request, and mumbled exclamations kept coming out of his masked mouth. As a wizard born from an ordinary person, he was simply astonished by Harry's hand.

In his eyes at this moment, Harry, who was processing the fingerprints of Lucius' wand with Hermione, seemed like an experienced detective!

If you take a pipe and a cane, maybe it will be more similar~

"Colin, this side is alright, come and take a picture."

"Okay~" The little fanboy responded happily, and rushed over.

If Harry is really a detective, what about himself?

Will it become the detective's right-hand man?

"Very well, in this way, the fingerprints of the wand can be regarded as obtained."

Harry was unaware of Colin's inner drama, because he was now immersed in the joy of discovering the complete chain of evidence.

After treating Lucius' wand in the same way, Harry got a batch of clear palm marks on the wand as expected.

In this way, all the fingerprints on the diary and wand were obtained, and the only thing left was the final confirmation and comparison.

"Luna, can I ask you to do a comparison? I need to find the same fingerprint as the wand in this diary." Harry finally found Luna, and asked seriously, "When Colin will After the photos are developed, I also need you to mark the fingerprints on the evidence and the traces in the photos correspondingly."

The matter involved the magic world. If Harry sent the results to the police for inspection, it would probably involve a series of troubles such as filing a case, investigating, and recording a statement.

Therefore, the only one who can help Harry right now is Luna with keen insight.

As long as she can produce the exact fingerprint comparison result, Harry can use this as evidence to ask Dumbledore for help. In this way, Lucius may be brought to justice!

Of course, Harry also knew that this was only a possibility...

"It's not a very difficult job, but I don't think you can get the results you want."

Only this time, Luna did not immediately agree to Harry as usual, but instead poured cold water on him.

"Hey, can you say something nice at this time?" Hearing this, Hermione immediately widened her eyes in dissatisfaction.

"I don't know whether these words are good or not, but I just told Harry the facts that may happen in advance." Luna didn't think there was anything wrong with her words, "This kind of thing is left after the quivering maggot crawled over. Traces, other people may not believe it, just like...you don't believe in the existence of the horned snoring beast."

"What did you say?"

Luna was saying that what Harry had done was useless, and those who needed evidence would not admit it, and Hermione could hear that of course.

But it was because of this that she was angry.

Because she is also a wizard of ordinary people's origin, she agrees with the evidence of this reality very much.

What's more, she would never allow others to belittle Harry's efforts at will!

Even if this person is Luna!

"That... can I say a few words?" Suddenly, Colin interjected weakly, "I don't think everyone needs to argue about this matter. Isn't it a happy thing to be able to find the key clues of the case yourself? ?"

"Hmph!" Hearing Colin's words, Hermione snorted dissatisfiedly, but she was not as tense as before.

And Luna also had a flash of thought in her eyes, as if she was reflecting on her previous words.

Sometimes, outsiders persuading a fight is like adding fuel to the flames; but sometimes, for example, if it is a good-tempered gentleman like Colin who is persuading the fight, everyone will give him some face even if he is angry.

"Anyway... I'm really happy now!" Seeing that the two women seem to have stopped arguing for a while, Colin continued, "I'm very grateful to Harry for inviting me here, and everyone's cooperation just now is really tacit, and it's also very good. Pleasant. That feeling...is like a detective agency in novels and TV dramas!"

In England, detective works are undoubtedly an enduring and popular subject, and almost everyone from the very old to the children are very enthusiastic about it, and the image of detectives such as Sherlock Holmes is even more well-known to every household.

Colin is also a small fan of detective themes, so when he found out that he was actually helping his idol Harry to search for evidence and investigate the case, one can imagine the excitement in his heart.

Especially since he also knew that what Harry was investigating was actually the mastermind behind the Chamber of Secrets, the real culprit who caused him to be petrified, so he felt even more that he couldn't stay out of it!

So, for the guys who are just working together, Colin really doesn't want them to have conflicts.

"Colin is right. It is always a pleasure to find evidence, so there is really no need for everyone to argue about it."

Harry called out to stop the tit-for-tat confrontation between the two girls. He stepped forward and took Hermione's hand, and first calmed down the angry schoolgirl.

After that, Harry looked at Luna very seriously.

"I admit... Luna, what you said may be right, but I have to give it a try anyway!"

At this moment, Harry's attitude is extremely firm!

He was a forensic doctor in his previous life, and his fingerprints were the only evidence in the court that did not require circumstantial evidence. It can be said that he was the most authoritative existence in the forensic process.

So even though Harry knew that submitting evidence that ordinary people would use in the wizarding world would likely encounter many problems, he still had to take this step!

Because this is his account of his past self and the profession he has been engaged in all the time!

It is certainly a matter of great satisfaction for Lucius Malfoy to be punished as he deserved.

But even if the matter failed in the end, Harry felt that there was no need to worry too much.

Because this will allow him to understand more clearly the rules of the game in the upper-level political circle of the magic world.

"I'll help you! These fingerprints, I will help you clearly identify them!"

Luna seemed to read something from Harry's eyes, knowing that the other party would do this no matter what, so she firmly agreed to this request, which she thought was just useless effort.

"Thank you very much!" Harry gratefully thanked Luna, and at the same time looked at the other two people in the room, "I am also very grateful to Hermione and Colin, thank you for spending the whole afternoon with me crazy. In addition, I feel that the detective agency that Colin mentioned is actually quite interesting~”

In fact, if you think about it carefully, the four people in the room are enough to support a complete detective agency.

Harry is in charge of evidence collection and forensic identification, Hermione is in charge of factual reasoning and data collection, Colin can assist with take-away photos, and the rest of Luna can not only compare the details of evidence, but also rely on intuition to blindly guess criminal suspects. people…

The small group of four used their spare time to receive some odd commissions. It was good for entertainment and relaxation.

Maybe, they will be able to unearth many secrets of Hogwarts' past that are like chambers of secrets~

Chapter 190 Hermione Doesn't Need To Hurt Herself To Make Changes

To be honest, Harry felt like he seemed a little weird lately.

He has always been a little puzzled, why is he so concerned about the troublesome thing of substituting for first-grade children.

It can't be because there is Luna in the class...

His ultimate pursuit as a student is to pass the test, but he never thought that once he became a teacher, he would start to be dedicated to his job.

Defense Against the Dark Arts, this class seems to have a special magic power, which will always attract Harry unconsciously, turning him into a dedicated scalper every minute.

The consequence of doing so was that after the Chamber of Secrets incident was completely over, instead of getting any leisure, Harry became even busier.

Preparing the lesson plans for black defense courses will take up a lot of his time, and he has to attend classes himself, and the most important thing is to take care of the magical animals in the box. Basically, he wants to break a second in half every day, and he doesn't have much time. Left alone with Hermione.

And recently, Harry has also generously helped Filch share a lot of night watch work, under the pretense of allowing Filch to have a private meeting with Mrs. Pince... er, a date~

But actually...

Hogwarts was very quiet at night. Normal people should have gone to bed at this time, and only some guys with other motives would continue to wander in the corridors.

"Hey, Mrs. Norris, please don't bark right now~"

Harry used the invisibility cloak to wrap Mrs. Norris carefully, and after confirming that Filch would not be back in a short time, he took it to the eighth floor carefully like a thief.

At the door of the Room of Requirement, Hermione was waiting there with Crookshanks in her arms.

The ginger-yellow male cat seemed a little irritable at the moment, and his four bow-legs were kicking eagerly at the same time.

As for Harry, Mrs. Norris even raised her ass impatiently...

"Meow!"*2

"This... let's go in first."

After meeting, the two cats meowed before anyone had time to say hello. Seeing this, Harry had no choice but to go into the Room of Requirement with Hermione first.

Hmm, the room full of clutter at night, the teenagers and girls with awkward faces, and the vivid cat in front of them...

"I think I must be crazy, to watch Crookshanks and Mrs. Norris here at night... Anyway, it's all your fault!"

The schoolmaster girl gave a dissatisfied glance at the person sitting next to her, seeing that the other person was actually watching with great interest, she couldn't help pinching his waist fiercely.

Hmph, if this guy hadn't fed some basilisk meat to two cats last time, things wouldn't have turned out like this!

Of course, Hermione herself would not refuse the fact that Crookshanks could let Mrs. Norris become her mother, and she was even a little proud of it.

It's like a pig that has been pulled hard by one's own family, and finally burrowed into someone else's cabbage.

When making this metaphor, the schoolmaster girl obviously ignored a fact...she herself is also a cabbage~

"Hey, can you be gentle~" Harry complained with a bitter face, "I really can't blame me for this, I just kindly gave them another meal, who would have thought that it would end like this."

Crookshanks and Mrs. Norris are not young cats, maybe they have been depressed for a long time, and the performance of these two cats in heat can be described as extremely intense.

According to Hermione, after Crookshanks went back that day, he became irritable, not only screaming loudly, but also tearing things up in the dormitory.

It took Hermione a lot of effort to subdue it and let it stop temporarily.

And Mrs. Norris's side is similar, she is completely in a state of dying if she doesn't do anything, and besides comforting Mrs. Norris, Harry has to be on guard at all times that Filch will find out the clues, but it is really He was exhausted.

What's more, these two cats can't be separated for too long. As far as their current state is concerned, unless Mrs. Luo Lisi successfully conceives, otherwise these two cats will definitely not stop here.

Even with the master behind them, they can only have private meetings in different ways.

From abandoned classrooms to suitcases to today's Room of Requirement, they basically visited all the places on the Hogwarts campus where couples could have an affair.

"But I think it's quite good~" Harry took Hermione's hand naturally, "Thanks to this pair of anxious little guys, we can spend more time together. And when the kittens are born , and we can take care of them together.”

No matter how old they are, as long as they are in love, they will definitely want to be together all the time. If you don't believe me, just look at Filch's performance.

Harry was naturally no exception, so he was actually quite grateful to these two cats now, at least they were used as an excuse for Harry to ask Hermione out at night.

Or just tell her directly, 'I miss you, let's go out to have an affair together tonight', Hermione will most likely let him drink Northwest Wind all night.

"Hmm~" Hermione replied softly, resting her head on Harry's shoulder.

"Hermione..."

Harry was slightly stunned. To be honest, he felt that Hermione was a bit strange recently.

Especially when they were alone, Hermione seemed a little too quiet.

It's not that Harry doesn't like such a gentle and watery Hermione, it's just that it deviates too much from her usual image.

Would Miss Granger still be her if she wasn't domineering and condescending in everything?

Moreover, Hermione has even started to go out with light makeup recently, which was absolutely impossible before.

So...huh?

"This smell is...bird snake eggs?"

The fragrance of the girl's body lingered around Harry, but while Harry was savoring it carefully, he suddenly smelled a special smell in the back of the hair, which was almost exactly the same as the one he had smelled on the eggshell of a bird and snake.

"Hermione, Lockhart's shampoo was actually taken away by you, right?"
