Hogwarts starts with stealing power.

Seeing that Lin Xia was very interested in this, Professor McGonagall said a little more.

“The reason why there is no pattern is that pollutants are generally produced in two ways.

One is to change the strange objects in the wizarding world through the power of the evil god world, so that the strange objects become dirty and filthy and transformed into pollutants.

The other is to bring pollutants directly from the evil god world and use them in the wizarding world.

But no matter what kind of pollutant it is, once it is purified, many wonderful reactions will occur. We call this reaction the game of two forces. "

Professor McGonagall felt that it would be difficult for people to understand just by talking, so she waved her wand lightly, and the two quills on the table suddenly deformed.

She used a feather pen to illustrate the process of the reaction, and the object she used as an example was the flash firework exploding candy that Lin Xia had cleared away.

"The process of evolution is the process of using the power of the wizard world to completely flatten and infiltrate the evil god world with its power."

The flashing fireworks and exploding candies in front of the table were surrounded by a brilliant aurora.

Lin Xia looked down and could see that the candy was gradually twisted and deformed under the destruction of the aurora, and an unknown force was repeatedly beating the candy.

Lin Xia's eyes were filled with deep thought.

She saw none of these things as she cleared the candy.

Professor McGonagall must have slowed down the bright light that she saw at the time by dozens of times, so that she could clearly observe what happened at that moment.

Under her gaze, the flash firework explosion bomb could not withstand the force of this change and immediately disappeared.

Professor McGonagall's voice came from my ear: "Some items have been reborn under this special game and have awakened better abilities.

But some objects could not withstand the clash of these two forces, and were completely broken into pieces during the game, turning into a pile of scrap metal, or simply disappeared.

The wizarding world currently calls this gaming power the power of transformation.

It’s just that we haven’t figured out the mechanism of the conversion yet, so we can only try to purify the pollutants through human intervention and turn them into something useful for the wizarding world.”

McGonagall paused here and sighed with some regret.

"Because the pollutants are too dangerous and there are very few wizards who are not affected by them at all, the experiments have been delayed.

We have to wait a long time for each new data because there is too little data to make effective conclusions at present.”

Lin Xia did not make big promises and say that she could understand the transformation mechanism and solve the problems of the wizarding world.

Although she knew that she already had this ability, she was still studying at Hogwarts and was still a student, so she tried to keep a low profile.

She had already asked Professor McGonagall for permission to observe the manager of Honeydukes who was locked in the dungeon, and to watch the changes in his body and mind every day. This behavior was actually somewhat dangerous.

However, considering that she has already cleared the pollutants once and been nourished by the unique fragrance, she seems to be accepting it well now.

Hogwarts should have secretly raised her level and opened up more resources for her, so Lin Xia's idea was not too rash and bold.

Lin Xia thought for a while, and suddenly said: "Since we have purified the pollutants, we may be able to obtain rare items that can be used in the wizarding world, and the effect of this kind of rare item will be even more powerful than ordinary rare items.

So is it the same in the evil god's world?

When the evil god world pollutes the rare items belonging to our world and transforms them into items that are exclusively used by the evil god world, if the transformation is successful, will the power be quite impressive?"

Professor McGonagall looked at Lin Xia with appreciation.

“Your guess is correct, so once pollutants are discovered in the wizarding world, the danger level of the pollutants will generally be very high.

Even if it is not high, its special ability will be very strong.

We must be vigilant about every pollutant we encounter, even if it seems harmless.”

Lin Xia didn't know what she was thinking of, and smiled: "Professor, the forbidden book I read also introduced how to use some purified magical objects.

The methods of use given in the forbidden book are all very strange. Some require following a certain ritual first, while others require a specific action to be performed before they can be activated...

It’s a pity that I don’t have this special purification item, otherwise I would like to do an experiment to see if the methods given in the book are effective.

I am curious, since this magical object that has been transformed through purification is so powerful, are there any restrictions on its use?"

McGonagall shook her head: "Normally there is no limit, because such rare items are difficult to obtain. The Ministry of Magic cleans up a batch of pollutants every year, but only a few of them can be turned into rare items, and most of them disappear in the purification process.

It was so hard to come by, so there are no restrictions on its use.”

At this point, she suddenly glanced at Lin Xia and said meaningfully: "If one day your little wizard gets this kind of purification item, you can also use it as long as you input magic power."

Lin Xia smiled lightly and did not answer Professor McGonagall's question. Instead, she said, "I hope we can have such an adventure in the future."

It was half an hour later when Lin Xia left the office.

She walked to the laboratory unhindered, but when she passed a corridor, she suddenly saw Mikkel distributing papers to the little wizards.

Lin Xia silently used the extrasensory spell to look at the paper. After a while, the contents written on the paper came clearly into her eyes.

She raised her eyebrows. It said -

[New Wand Production Change Survey]

Q1: Can you accept changing the magic wand into a sword?
Q2: Do you prefer using a sword to cast magic rather than using a wand to cast magic?
Q3: Do you think it would be more powerful if the magic wand was replaced with a sword, and every battle was fought with sword moves?

Q4: Do you support researchers changing the magic wand into a sword?
Q5: Are you willing to spend one copper kart to support?
Q6: Would you share this brilliant idea with your friends?

Q7: Thank you for your cooperation. After filling out the form, you can give it to Mikel Bain, a third-year student at Hogwarts Gryffindor College!

A strange look flashed across Lin Xia's face.

She had heard Draco mention before that Mikel was very proud and had chosen the dual assessment of outstanding students for research talents and combat talents, and was currently doing the assessment task for research talents.

So, making changes to the shape of the wand is his research topic?

Doesn't he know that the wands in the wizarding world have undergone many improvements in style, and after years of changes and the wizards' usage habits, they were finally fixed into a staff shape.

Seeing that Mikel would stop and communicate with the wizards enthusiastically after handing out each questionnaire, Lin Xia couldn't help but shake her head.

Forget it, as long as he is happy.

Pushing open the laboratory door, Ron and others were not waiting in the lobby. Lin Xia was a little surprised to find that they had already walked into the laboratory to do experiments.

She couldn't help but nodded.

The changes in the students this school year were noticeable. Everyone was obviously calmer and more composed than before. Even Ron, the loudest one, had become somewhat indifferent to fame and fortune.

However, the most obvious change was in Hermione. It wasn't that she became calmer than before, but she became a little more violent than before.

Ron had complained to her many times, and Hermione would kick people if they disagreed with her.

Lin Xia thought, maybe this is the belated rebellious adolescence?

She waved her wand and used a telepathic magic to have her companions stop their experiments, seal the area, and then come to the lobby.

After a while, a few friends appeared and looked at Lin Xia expectantly.

Lin Xia repeated what Professor McGonagall had said, emphasizing, "The professor said that even little wizards like us can use this kind of purification artifact, and it won't be dangerous."

Hermione was as sharp as ever.

She pondered and said, "Why did Professor McGonagall suddenly say those last words? Has she guessed something?"

Ron said excitedly, "Does that mean we have a rare item? Is it something that belongs to the team? I've never played with something like this before!"

Lin Xia took out the [Illusionary Snail] in her hand.

From the appearance, this conch is no different from the one seen yesterday. As long as she doesn't say it, no one will notice that this conch is not that conch.

She listed all the abilities of the Illusionary Snail, but did not specifically explain the enhanced abilities.

"Although this conch is very powerful and can split into daughter snails infinitely, and can be placed anywhere to help us collect information, its concealment and defense capabilities are very weak. We cannot move it frequently, and we must be careful when choosing a location for it."

After the friends had understood almost everything, Lin Xia continued, “Given the fragility of the mother snail (once the mother snail is destroyed, all the daughter snails will be destroyed along with it), I suggest that the mother snail be kept with me.

If you have a place you want to put it, you can ask me to split the sub-snails, or I can give you a few sub-snails that have already been split, and you can put them wherever you want."

Ever since Ron heard about the ability of this conch, he lost interest in it. He thought it had some attacking capabilities, but he didn't expect it was only eavesdropping ability.

He even had a doubt and asked, "Is this strange thing useful? It can only be used to monitor information."

Draco said without thinking, "Of course it is useful. Nowadays, we emphasize information warfare. If you know the abilities and weaknesses of a certain wizard and fight against that wizard specifically, even a high-level wizard will most likely be killed by a low-level wizard."

Harry stared at the conch in Lin Xia's hand and suddenly muttered to himself, "Can I put a conch shell in Professor McGonagall's office?"

"Harry, you--" Hermione frowned and looked at him with great worry.

Ron was no exception and also looked worried.

Lin Xia and Draco looked at each other, as if something had happened that they didn't know about.

Harry reacted and said quickly: "You misunderstood me, I didn't want to collect important information about the wizarding world, I just wanted to learn more about Sirius from Professor McGonagall.

Our information flow is far less flexible, extensive and rapid than that of professors. I think if Sirius didn't come to me, the professors at Hogwarts would be the first to find him!"

Hermione said bluntly: "Harry, I want to believe you, but I am more afraid that you are not in your right mind and can be manipulated by others.

The ability of this conch is both important and unimportant. It all depends on how it is used.

I suggest that every time the location of the split snails is placed, it should be decided by collective vote, and not be placed privately. "

Hermione said decisively, "Put the snail in Professor McGonagall's office. I vote against it! Professor McGonagall is very perceptive. I don't think the Illusionary Snail can be hidden from her."

Harry looked a little ugly, and a little aggrieved.

He felt that no one understood him and everyone misunderstood him!
It was as if he had relived what happened in the Chamber of Secrets, the darkest moment when everyone thought he was the heir of Slytherin.

However, the next second, Hermione changed her tone.

"But I'm only against putting it in Professor McGonagall's office. Can we discuss which professor's office would be better?"

After discussion, they finally decided to put it in Professor Lupin's office.

There are several reasons. First, Professor Lupin is a new professor. His office is relatively simple and students come in and out all day long, so it is easier to arrange.

Secondly, if Hogwarts really found Sirius Black, Lupin, as the professor of Defense Against the Dark Arts and with extraordinary combat power, would definitely be notified by the school to encircle and suppress Sirius Black.

Last but not least.

If Lupin discovered the Snail of Illusion and found out that they were the ones who released it, given their friendship with Professor Lupin, he should be able to show leniency and not hand them over.

Although Professor Lupin looks a little depressed, he is a good professor who cares about his students and is very approachable.

Even the timid Neville liked to stay with Professor Lupin, so the little wizards all agreed that he was able to communicate.

Ron asked: "Then the question is, who should we do this?"

Lin Xia looked at Harry: "Come on."

Harry was stunned.

Lin Xia said, "You go ahead and release it. Ron and Hermione will cover for you. Since you want to get information about Sirius from the professor, then you go ahead and release it."

Harry nodded subconsciously.

After discussing this matter, the young wizards saw that it was still early, so they returned to their respective laboratories to conduct experiments and record data.

Hermione had not taken a few steps when she felt her little finger being gently pulled by a silk thread. The movement was very gentle, but it was noticeable.

Hermione turned her head and saw Lin Xia and Draco both winking at her.

Hermione quickly understood what was going on.

After Harry and Ron went in, Hermione walked over to them and said thoughtfully:

"Yesterday we returned to the Gryffindor common room and discussed with Harry the strangeness in his mind..."

Draco also talked to Lin Xia about Harry's problem, but Lin Xia was very determined that Harry was not disturbed by the evil god's whispering.

After practicing "Nine Heavens Mysterious Yang Secret Records", her body became the best detector.

After so many contacts with Harry, there was no abnormality in her body, which showed that Harry was fine.

But Harry's current condition is also quite worrying.

Lin Xia suddenly thought of the sequelae of Voldemort's splitting of his soul and making Horcruxes, and couldn't help but ask: "Do you think Harry's current symptoms are similar to schizophrenia?" (End of this chapter)
