At dusk, outside Koizumi Hongzi's house, Koizumi Hongzi looked at Ye Siyu who was leaving, and couldn't help but breathe a sigh of relief.

When she met Ye Siyu before, she was very curious about Ye Siyu, a person who suddenly appeared and gave her a great sense of crisis, but after coming into contact with Ye Siyu, she didn't want to have anything to do with Ye Siyu at all, and understood why Ye Siyu gave herself such a big sense of crisis.

In Koizumi Hongzi's opinion, Ye Siyu is a madman, and he dares to mention the Dark Lord who shouldn't have a name, and she doesn't care at all, she even sees Ye Siyu's idea of looking for the Dark Lord.

If you let others know that you are in contact with such a person, not to mention that she is the heir of red magic, even the minister of the neon magic department may suffer, in order to let Ye Siyu, a troublesome guy, leave, she lent out all the magic books she basically treasured.

Feeling the resentment emanating from Koizumi Hongzi behind him, Ye Siyu, who was carrying a bag of magic books behind him, didn't care at all, he was in a very good mood now.

During Koizumi Hongzi's chat, Ye Siyu also took a few magic props from Koizumi Hongzi to check, and he found that his world origin had increased, which made him more sure that the world he was in was the world of Harry Potter.

Although this world is the Harry Potter world, Harry Potter is just what happened in one area of this world for a period of time, and it can't summarize the whole of this world, and the things shown in it are not complete, so Ye Siyu also learned about the specific situation of this world from Koizumi Hongzi.

In this world, there are far more magicians than in the movies.

The power of magic spreads all over the planet, not only in Britain and the United States, but also in various regions such as Huaxia and Neon, but these regions have different names for magic users, in Britain the name is wizard, the United States is called magician, and in China the name is warlock, neon is called onmyoji, which is very local.

At the same time, Ye Siyu figured out why he couldn't detect the reason why others used magic.

If in other worlds, magic is one of many extraordinary abilities, then in this world, magic is the only extraordinary ability, its level is higher than all powers, and the creatures that can do magic and those who can't do magic are two personalities, and they belong to two dimensions.

Although Ye Siyu has extraordinary power in the subjective sense of this world, objectively he is still a human being who can't 'magic'.

Unless Ye Siyu learns magic or is cast with those physical magic, otherwise magic is a mysterious existence that he can't detect.

At the request of Ye Siyu, Koizumi Hongzi cast a lot of lock-picking spells, lighting spells, repair spells and other more common magic in this world.

Ye Siyu, who saw the process of casting these spells, was directly dumbfounded, because he couldn't understand the principle of these spells at all, because from the beginning of the spell to the end of the spell is the beginning and end of a spell, and these spells are not the obscure spells that Ye Siyu used to cast to communicate the laws of heaven and earth, but a very straightforward meaning.

For example, the lock-picking spell, Koizumi Hongzi's spell is a very simple lock-picking Japanese.

The reason why Ye Siyu couldn't understand the spell in Koizumi's mouth when she first met her was because she used magic to disrupt the words that others heard, which is the most common technique used by magicians in battle, which can prevent the enemy from knowing what spell she is using.

After knowing the reason for Ye Siyu's arrival, Koizumi Hongzi withdrew the gibberish magic.

After seeing the magic of Koizumi Hongzi, Ye Siyu felt that the magic of this world could be summed up in one word, that is, all wishes come true.

That's right, it's all you want.

If you want to open the lock, then you can open the lock, if you want to repair it, then you can fix it, there is no process at all, and the result can be obtained directly.

Ye Siyu also found that because of the extremely high level of magic in this world, the magic in this world is more idealistic.

The strength and efficacy of magic in other worlds is determined by the user's mental power and the amount of energy used, and in this world where the energy activity is infinitely close to that of the non-demonic, the power of magic depends on the will of the caster.

The role of magic is no longer as complex as starters and fuel, it is only fuel in this world.

This kind of weird magic was the first time Ye Siyu had encountered it, at least there was no such thing in his magical knowledge.

However, this kind of thing also gave Ye Siyu a hint on how to use magic in this world.

After coming to this world, Ye Siyu tried to use magic, but no matter what spell he used, he couldn't use even the simplest magic like ignition, so he couldn't understand what was going on, and after seeing the process of Koizumi Hongzi casting magic, he felt that he should change it and not think about magic so complicated.

After returning to his residence, Ye Siyu began to read magic books borrowed from Koizumi Hongzi to learn magic.

The skills of using magic recorded in the magic books, just as Ye Siyu quit the group before, the magic of this world relies on ideas, not skills, the stronger your ideas, the simpler the magic.

Of course, in order to use magic better, magicians in this world usually need to use magic wands to help condense magic power, and Koizumi Hongzi's magic wand is the scythe.

And in this regard, Ye Siyu doesn't need it, because his energy mobilization is the second in this world, and there is absolutely no one who can call it the first.

"Fire."

After determining how to use magic, Ye Siyu immediately began to use magic according to the content of the book, he threw away complex spells, threw away tedious energy mobilization, and only used the simplest language, and at the same time had only one thought in his heart, that is, flame.

Be quiet......

Nothing has changed.

"Fire."

Ye Siyu didn't care about this, and repeated in his mouth.

The result is the same as before, nothing has changed.

"Fire."

"Fire."

……

The time spent in Ye Siyu kept saying the word fire, which was extremely boring.

But even so, Ye Siyu's patience has not been worn out a bit, on the contrary, as time passes, the idea of fire in his heart has become more and more profound.

"Whew!"

After I don't know how many times I tried, a little spark appeared in front of Ye Siyu.

Mars was fleeting, as if it had never appeared, but this was a good sign, which made Ye Siyu more and more focused, and he had already felt some feelings.

"Fire."

As Ye Siyu's words fell, a finger-sized flame appeared in front of Ye Siyu out of thin air.

"Wind."

The flames that had been the size of fingers suddenly swelled and became the size of a palm.

"Water."

A stream of water appeared, flowing next to the flames, forming a water circle.

"Electricity."

There was a crackling, and one razer after another appeared in the water.

Ye Siyu kept trying to visualize various magic elements, and after trying all the basic magic elements, Ye Siyu stopped, and at the same time, a smile appeared on his face, he had mastered the key point of using magic in this world.

Of course, it doesn't mean that Ye Siyu can use all the magic now, all he can use now is the fireball technique, the water ball technique, etc., which are relatively simple and completely spell the amount of magic power, and the more complex idealistic magic like curses and cause and effect, he still can't use them, and it takes a very long time of practice to do it.

But that was enough, at least for him to knock on the door of this world's magic.

After learning the magic of this world, Ye Siyu no longer continued to focus on magic, but on how to obtain the origin of the world.

From the mermaid tears and Koizumi Hongzi's magic props, we can know that the origin of the world in this world is related to the magic product, but these magic props do not contain much of the origin of the world.

At present, Ye Siyu has seen three levels of magic props at the planetary level, the stellar level and the cosmic level, of which the planetary level provides 0.001%, the stellar level provides 0.01%, and the cosmic level provides 0.1%, and the overall relationship is increasing, if you are not mistaken, the cosmic god level can provide 1%, and the main god level can provide 10%.

This doesn't look bad, collect a hundred cosmic-level magic props to make up the origin of the world that left this world.

But under the guidance of Koizumi Hongzi, Ye Siyu knew that the planetary-level magic props of this level were already very high-level props in a world where magic was declining and magical beasts were becoming fewer and fewer, and only the rich could afford to use them, and the stellar level was even more precious, and only some relatively powerful family forces had them, as for the universe level, that was the treasure of the treasures, and Koizumi Hongzi, the long-standing magic family, only had two, namely her sickle and a crystal ball specially used for divination.

It can be seen from this how difficult it is for Ye Siyu to rely on ordinary magic props alone to gather enough world origins.

Therefore, Ye Siyu did not plan to collect magic props slowly, but went directly to the United Kingdom.

There have been many rare props in the Harry Potter story, among which the most worthy of Ye Siyu's attention are the Deathly Hallows and Voldemort's Horcruxes, all of which are the top magic props in the wizarding world.

Although it is not clear about its specific level, at least it is also a cosmic god-level or even a main god-level prop, Ye Siyu believes that as long as he gets these props, then he will be able to make up the origin of the world.

It's a pity that Ye Siyu is not very familiar with the plot of Harry Potter, and he has only watched one or two movies and learned about some of them, so it is difficult for him to get any useful information even if he is looking for memories, and he does not know what time period the plot takes place.

As for where it is easiest to help Ye Siyu get in touch with the British wizarding world, Ye Siyu also thought that it was Diagon Alley.

But before going to the UK, Ye Siyu still needs to practice magic for a period of time and familiarize himself with various knowledge of the wizarding world, so as not to encounter some difficult things to solve after going to the UK.

……

A month later, in London, England, Ye Siyu strolled through the streets.

During this month, Ye Siyu kept practicing magic, and with his ability, he was able to easily deal with a magician like Koizumi Hongzi, who was immersed in magic and kept practicing.

Of course, the deal here is in terms of elemental attacks, and as for the secret techniques such as lock-picking spells, he is still not proficient, but it is enough for Ye Siyu to deal with most magicians.

At the same time, Ye Siyu also found that after learning the magic of this world, his perception ability also recovered.

Because he 'understood' magic, he could perceive that the rules of this world were indeed an eye-opener for Ye Siyu.

According to the information provided by Koizumi Hongzi, who had studied in the UK, Ye Siyu quickly found Diagon Alley.

Diagon Alley is the busiest shopping street in the British wizarding world, and many of the leading brand stores in the wizarding world are located here, which is hidden in the small patio behind the leaky cauldron bar that Muggles can't see, and can be accessed by hitting a specific wall tile next to the dumpster with a magic wand.

And the other alley not far from Diagon Alley is the Tumbledown Alley where most of the dark wizards gather, and Ye Siyu can definitely get the information and magic props he wants from it.

Ye Siyu walked into the Leaky Cauldron Bar and could see that it was full of people wearing British nineteenth-century retro costumes drinking inside.

The moment Ye Siyu came in, the originally lively bar instantly became quiet, and everyone looked at Ye Siyu, and they felt an uncomfortable breath from Ye Siyu.

Ye Siyu also found that the atmosphere was a little weird, but he didn't care, and went directly to the patio behind the Broken Cauldron Bar.

"Who's that Oriental? Have you seen that? ”

"No, it's supposed to be new."

"Did you just feel it?"

"Well, it's weird, it's not like a good kind."

"Do you want to report it to the Ministry of Magic?"

"Don't get into trouble."

……

As Ye Siyu disappeared into the bar, the bar became lively again, but the content of their discussion changed from the latest magic props or gossip to Ye Siyu, and some people left directly, ready to report this rather strange matter to their own forces.

Ye Siyu didn't know anything about the bar, and even if he knew, he wouldn't care.

After a few taps on the wall, the bricks of the wall moved one by one, and after a few seconds a gate was formed that led to a lively street.

Ye Siyu did not immediately cross the gate and enter Diagon Alley, but was observing the gate, this stone wall was not an ordinary wall, but a spatial portal to the mysterious area.

According to the information provided by Koizumi Hongko, he knew that Diagon Alley or Hogwarts were not on Earth, but in Earth's annex space.

After feeling the breath of the spatial portal in this world, Ye Siyu crossed the spatial portal and entered the diagon alley, ready to start collecting intelligence, and Ye Siyu's first target was the Prophet Daily newspaper.

The Daily Prophet issues an issue every morning, and when something major happens, it also issues an evening newspaper, which can be said to be the largest intelligence center in the wizarding world, and can provide Ye Siyu with a lot of information.
