Soon after, Professor Sgrahorn was discharged.

During this time, Ralph upgraded his feather double with some of the knowledge he gained from the Ravenclaw Tiara.

Not only that, but he also exchanged his magic power for some star spring water, soaked the feathers that were ready to be turned into stand-ins for a while, and added some moon dew.

This allows the stand-in feathers to contain and absorb more mana, and creates a cycle of mana with the outside world.

When it comes to retrieving memories and simulating thinking, less mana is consumed.

With this knowledge, Ralph builds a more efficient and energy-efficient way of retrieving memories that can be used not only for feather doubles, but also for himself.

The knowledge inside the Ravenclaw crown is not something that can be obtained casually.

First of all, the user must be a student of record at Hogwarts, a young wizard whose name has been written on the Book of Acceptance, and who has successfully signed a contract with Hogwarts in the Black Lagoon.

Of course, Ravenclaw students are a plus.

After that, it needs to be recognized by Hogwarts Castle, which is a key to open the crown and uses to open the knowledge base inside.

There are no clear criteria for recognition at Hogwarts Castle, and Ralph was recognized the last time he stopped the Kemeralmon.

The sign is a black raven flying towards him, eventually merging into his body.

And so on, Gryffindor is a red lion, Hufflepuff is a yellow badger, and Slytherin is a small green snake.

It's the equivalent of a castle marking you as if you were its person.

The marks seem to be invisible, though, as no one has ever been heard talking about them.

After obtaining the key, the knowledge in the crown does not enter the user's brain at once, which is probably not affordable for anyone except Ravenclaw himself.

The knowledge within the crown has been classified. It will seal the basics of each category with magic and gently send them into the user's memory.

When consciousness touches the sealed knowledge, it will be hindered, and it will need to solve the problems that come with the seal in order to temporarily obtain a key to enter the knowledge.

There is a time limit for the key to get to solve the problem.

The key obtained from the first problem solving is valid for 1 day; the second is 3 days; The third and subsequent times are 7 days.

Each time you solve a problem, there will be one less seal on your knowledge, but after solving all the problems, this knowledge belongs to you.

Ralph discovers that the seal on the knowledge bubble is actually an advanced application of the Locking Charm.

Only here, the [Locking Spell] has been changed.

The Unlock Charm is like a light in the dark that is used to help you find the right lock so that the key you have in your hands is useful.

Here, we don't need to use the [Unlock Spell] to access it, we can answer the questions inside.

Either the [Unlock Charm] corresponding to the [Locking Charm] on the surface of the bubble has been replaced with consciousness, or something peculiar, such as the permission of Hogwarts Castle or something.

Although all the problems have been solved and all the seals have been opened, they do not really belong to you at this time, and they can only be said to belong to you after thoroughly digesting and absorbing this knowledge.

Knowledge is recorded in books, and books belong to you, which does not mean that you have mastered the knowledge in them.

Once the Ravenclaw crown is irreparably damaged, these bubbles of knowledge disappear from memory.

In fact, when the user has thoroughly mastered the basic knowledge of a certain type, the bubble of corresponding knowledge will disappear and be replaced by the same type of improved knowledge.

However, when approaching the Enhanced Knowledge Bubble, we can also choose to go into the basics, but only if the seal on the surface of an Enhanced Knowledge Bubble is unlocked.

The crown is like a remote server, and when we put it on and give the correct password, it keeps the basics in our memory.

These basics are in our ocean of memory

Like a large bubble, suspended above the memory, the surface of the bubble has chains that intertwine and entangle it.

These bubbles are the access links left for us by the Crown server, and as long as the magic is still there, we can access the Crown server through the bubbles in our memory.

However, all of these require the aid of memory magic, and wizards who have not learned memory magic and are not proficient in accessing their own memories need to wear a crown on their heads when performing the above operations.

If you want to get in touch with the seal outside the memory bubble, you can do one more thing, and that is to answer a question about the Eagle's Head Bronze Knocker in person, and answer it to your satisfaction.

The Ravenclaw Tiara has a mysterious connection to Hogwarts Castle, through which the Tiara can find out.

This is followed by the wearing of the crown and the assessment of the crown.

The Ravenclaw tiara is more like an alchemical prop for passing on knowledge.

Ralph also learned a lot of knowledge and solved a lot of problems before he got the knowledge he wanted, so as to solve the problem that the feather double could not stay for a long time.

During this period, communication with professors was indispensable.

At first, he asked his neighbors questions.

But the neighbors in the back were also a little overwhelmed, and seemed to feel the feeling they had when they asked Ralph with the hardcover version of "Professor's Notes".

So, the neighbors asked Ralph to ask the professors.

From the initial letter exchange, Ralph was called by the professors to the second floor of the Hogwarts Benefit Store for a many-to-one teaching.

Professors always prefer students who are eager to learn, and at the same time prefer students who ask them questions.

Students like Ralph, who study hard during the holidays and ask in-depth questions, are undoubtedly loved by many professors.

During this time, he also got to know many professors of courses that he had not yet learned, such as the professor of arithmetic and divination, the professor of Muggle studies, and so on.

Among them, Professor Sinista, the professor of astronomy, also plans to invite him to the newly built planetarium at Hogwarts to observe the beautiful starry sky together.

However, under Professor McGonagall's gaze, Professor Sinista retracted his words.

It is said that there are still some dangers in it that have not been ruled out, and it will take a while.

Ralph didn't prostitute the professors either, and in his free time, he offered to help Filch share the cashier's duties.

Although there was only one magic cash register system, Ralph didn't need it at all.

Thanks to years of cashier experience, Ralph calculates prices even faster than Filch can manipulate the cash register system.

In addition to cashiering, Ralph also operates the auto-inked feather notebook, which is very versatile and very proficient.

This made Filch very envious.

With the exception of a few customers who didn't frequent Hogsmeade, the rest of the customers were not surprised that Ralph was here to register the cashier.

For the wizards who frequent Hogsmeade, they have seen Ralph as a waiter in every shop.

Not only at the cashier, but at times, Ralph would help Professor Sprout introduce the various plants to the customers.

During this time, due to the attack on Professor Sgrahorn, there was a lot less traffic in Diagon Alley and Hogsmeade Village, and everyone stayed at home honestly, but there was not a single yelling letter sent to the Ministry of Magic.

The Ministry of Magic knew that it was wrong, so it could only hold its breath and admit it.

Coupled with the slap in the face of the previous spy incident, they all have a fire in their hearts.

Although the flow of people has followed, the patrols in these two places have not been relaxed, but have become stricter.

It has been ordered that any wizard who makes a noise or covers his face must be stopped and examined.

This caused a lot of dissatisfaction, after all, not everyone knew the Aurors, they were all known by the Aurors, and it was inevitable that they would stop and check.

However, this really has to find something, which makes the people above happy and more determined to their thoughts.

They do it

For, it opened a green channel for those famous wizard family members.

After all, there are only a few of them, and in the wizarding world, everyone basically knows each other.

In the face of them, the Aurors all held an attitude of letting them go.

This kind of differential treatment made the members of the wizard family feel a little proud, and looked at the civilian wizards who were being examined with a condescending gaze.

But joy is always the same, and they can't be happy for long.

Tumbledown Alley ushered in another thorough investigation, a real strict investigation, without informing anyone.

The operation was directed by the Director of the Department of Law Enforcement of the Ministry of Magic, and all personnel who received the news, whether the Director or other staff members, were summoned to his office by the Minister of Magic, cut off from the outside world, and not allowed to pass on any information.

Not only Tumbledown Alley, but also the estates of some wizarding families that have been thoroughly investigated.

The Aurors were divided into two large groups and acted separately.

The merchants of Tumbledown Lane, which were still in business at the time, were unlucky, and they were all arrested by the Aurors and their goods were confiscated.

Some of those who tried to resist were directly hit by several [Stuna Charms] and [Disarming Charms], and looking at this pattern, it is estimated that they will have to go to St. Mungo's Magical Injury Hospital for a while before they can be judged.

Like the owner of the Borgin Burke shop, Mr. Burke, is still very clever.

Seeing this, he directly put his wand aside, raised his hands, and let the Aurors take him away.

He knew that as long as he cooperated, he would definitely be released, and at most he would be fined gold gallons, lose a batch of goods, and stay in Azkaban for a few days.

As long as it is done properly, you don't even need to enter Azkaban, that place is really not for people.

Dark, damp, cold, these are not the most uncomfortable.

The most terrifying of all are the Dementors, who are the guards of Azkaban, who do not need to be paid by the Ministry of Magic, and are the best guards they consider.

The Dementor wore a cloak that looked like it had been soaked in water, and had scabbed palms that looked as if it were rotting.

Wherever it passes, it is drained of all pleasure and reminds of the most terrible things, and the "mouth" under his hood sucks people's souls, known as the "Dementor Kiss".

One of the heaviest punishments in the Ministry of Magic is the "Dementor Kiss".

"Let's hope they'll get me out soon."

It occurred to Mr. Bock that he had sensed that something was wrong, and that with the goods in his shop, he would definitely be thrown into Azkaban.

Moreover, it may not be easy to deal with this time, he did not receive any news beforehand, which is already the biggest abnormality.

This means that the Ministry of Magic is moving the real grid.

The trip to Tumble Alley made them reap a lot of gains, and countless illegal and prohibited goods were neatly placed on the shelves.

Eugenia Jenkens, the current Minister of Magic, looked at the goods with excitement in her eyes, she looked at the directors behind her, praised the Aurors who had returned, and promised them an extra year of wages, which made the Aurors cheer at once.

Jenkens didn't care about the cheers of the Aurors either, looking at them with a smile on her face, which would be another great achievement since she took office.

Previously, she had completely secured the throne of the Minister of Magic because of her excellent handling of the pure-blood riots during the Squib*** period.

Now, she is looking forward to the return of the second team.

"Captain! Minister! We've got a call for help!"

An Auror rushed in from outside.

The Aurors stood at once, ready to go.

And the staff were in a mess, and they didn't know if they thought Voldemort had come in.

"Quiet!"

Jenkens cast the [Amplification Spell], and a loud sound echoed through the main hall, forcibly stopping the rioters.

Soon, the team set off for the place where the call for help was given.

In one of the Nott family's estates, several Death Eaters are battling the Aurors.

As if they were in a hurry, these Death Eaters had already cast an unforgivable curse, and the [Drill Heart Curse] and [Killing Curse] were released outside without their lives.

It was difficult for the Aurors to win for a while.

These Death Eaters were also helpless, they had known each other in private, and they wanted to get together and complain about what had happened in the past few days.

Who would have thought of running into an Auror patrol?

After knowing that it was the Aurors, they were glad that they didn't wear a mask or a black robe, otherwise they would really not be able to tell.

But, there is a pig teammate among them.

At that time, one of the Aurors opened the door with a cold face and asked if they were Death Eaters.

No sooner had they opened their mouths to deny it than a spell slashed across their faces towards the Aurors opposite.

The Auror on the other side was also stunned for a moment, is it so direct?

A dodge, shouting at a teammate, it's the enemy!

The battle was on the verge of breaking out.

The Aurors worked well together, and the enemy hid in the building.

A teammate can blow up the building where the enemy is hiding with a clean [Explosion Spell].

Then, another teammate added a Hurricane Curse to sweep away the smoke.

With a clear vision, they changed the terrain, conjured up obstacles in front of them, and gradually pressed towards the opposite side.

The leader here saw that the other party kept beating his arm with his wand, his eyes suddenly shrank, and he hurriedly released a signal for help to the sky.

Having participated in many battles with the Death Eaters, he knew that this was their call for help.

Normally, soon after the signal is issued, their companions will apparition one by one to the periphery.

This is also one reason why they have a hard time dealing with Death Eaters.

Their positioning and messaging are just too convenient and fast.

If you get this magic and use it on the Auror Squad, their mission success rate and safety factor will be much higher.
