Sending Shirou Emiya and Artoria to that world together, Ethan stopped paying attention.

Because of the synchronization of time flow, they can slowly hone themselves in that world.

Before setting off, both Emiya Shirou and Artoria were familiar with the various equipment on the Moon Goddess, including storage items and armor, as well as a range of weapons, especially how to call Luna in times of crisis.

In the event of an accident, Luna can teleport them back to the ship, as this is just a training to improve Emiya's strength, not to actually push him into the battlefield to his death.

"I don't know if Emiya Shirou can understand the principle of those sets of armor and copy it......"

Emiya Shirou can project shields and armor, but it doesn't last as long as weapons and consumes more mana.

But now Emiya Shirou has embarked on a completely different path, the projection magic he is learning and mastering now is very different from the magic used by Amya, and it can even be said that the projection magic mastered by Emiya Shirou is closer to the kind of chaos magic that Tony taught to the Scarlet Witch, but the type of item he 'creates' is relatively simple.

"After a busy day, it's time to go back to studying?"

"It doesn't matter if you don't go, right?" Rin Tosaka looked left and right, she might be the only one among them who went to Hogwarts to study seriously, and Illya and Leah might also be studying seriously.

The rest of them, such as Skaha, Logan, and Ethan, are essentially going there to play and vacation, and even if they are learning, they are only incidental: "Even if you used to learn the magic of that world in the beginning, you should have learned about it now." ”

The tacit understanding between Dumbledore and Snape and Ethan is not visible to ordinary students, but these few are still very clear, because they can easily get more knowledge from Ethan that can only be learned in the upper grades.

"There's one more thing I need to study and study after that...... There's really not much to do. ”

While chatting, several people came to the world of Harry Potter again.

"Time Converter?"

Ethan mentioned this thing in his spare time, but everyone didn't know what it was, but it was speculated from the name to be related to time.

In addition to teaching Emiya Shirou, Ethan is studying the power of time during this time, and often tinkers with a bunch of monster flesh and blood that he doesn't know from what world, and he is easily frightened when he occasionally bumps into him doing experiments, as if he is doing some evil experiment.

"Yes, time converter. ”

In fact, last semester, he was able to get this item through Snape's connections, because this item is not a special item in the Harry Potter world, but there are a lot of them - all of which have been destroyed.

It can be said that if the bunch of time turners are not destroyed, then whatever happens in the future can be saved through this plug-in prop, but in that case, the Harry Potter story may have to be renamed The Flash.

It's just that last semester, Ethan still has a lot of knowledge to learn, and the time converter thing has been pushed back a little, anyway, this thing is not in a hurry for the time being, and it doesn't matter if you get it later.

What's more, he knew that even if he didn't take the initiative to ask for this prop, Hermione should have already gotten this plug-in from Professor McGonagall, and then enrolled in all the electives in the new semester, with the posture of being a top student to the end.

"How do you solve the problem of your physical appearance?"

"Just use illusion to deal with it. ”

Ethan's body can't be said to have grown at all, after absorbing some of the energy of the Shadow Country, and usually being able to draw energy from the magic dimension, and even discovering that magic stones can be eaten as snacks, and all of them can be replenished into the body, his body has also developed somewhat.

It's just that compared to ordinary people, the development rate is very slow...... If when his body was first transformed into a divine body, he was in his early tens, after such a long time, he is now more than eleven years old and less than twelve years old.

Fortunately, Ethan's body is tall among his peers, and it is not too dazzling to be mixed with a group of children around thirteen or fourteen years old.

After returning to the world of Harry Potter, I simply packed up, got the class schedule for the new school year, and went to Diagon Alley to buy the books and tools I needed, and it all went well.

The world of Harry Potter was very quiet in the first few years of the plot, although there were some intrigues and tricks carried out by Voldemort's die-hard subordinates, but in general, what happened was just the 'child', and there was no catastrophe that threatened the safety of the world.

So as long as they don't get close to the Harry Potter protagonist, for Ethan, this is a peaceful world where magic exists and they can take classes in a school that teaches magic.

Even if you get close to Harry Potter and get involved in the plot, the trouble you encounter is not big, and it can be easily solved.

From the next few years onwards, though, things got a little sour, and the intrigue surrounding Harry became more and more widespread and involved more and more people. And the identities of these people are becoming more and more complicated, especially the chaotic situation within some ministries of magic, which leads to many things being clearly understood, but being troubled by a group of pig teammates.

This was originally none of Ethan's business, according to his plan, he would be able to learn everything he wanted to learn in the past two years, and no matter how bad it was, he could copy it into his magic book first, and then study it slowly when he returned.

But the stupidity of the Ministry of Magic really left Ethan speechless - because Sirius: Sirias-Orion-Black escaped from Azkaban, and the Ministry of Magic placed a large group of Dementors around Hogwarts under the pretext of protecting the young children of Hogwarts in order to hunt down Sirius, and considering the relationship between this man and Harry Potter.

No sooner had the train entered the vicinity of the Dementors' defensive circle than Ethan and the others sensed the breath of the magical creatures.

"It's an unpleasant breath. ”

Dementors are ghost-looking magical creatures, and Ethan can tell at once that Dementors are pure energy aggregates, with negative energy attributes, and because they are energy creatures, they are almost impossible to kill—in this world, the common way to deal with Dementors is to call the gods to protect the defensive spell.

"I'm actually curious how the Ministry of Magic would explain if the Dementors did kill a few students?"

Throwing a group of completely uncontrolled magical creatures near the school, even to capture Sirius, is an astonishing amount of stupidity.

Just as Ethan was speechless about how things were going on, the train suddenly stopped.

If I'm not mistaken, the next scene in the plot should be Harry Potter: Harry Potter is attacked by Dementors, and Professor Lupin, who happened to be resting in the carriage, fought off the Dementors and saved Harry Potter, so Harry later wanted to ask Professor Lupin to learn how to deal with the Dementors.

"A few of them came in the train. ”

This matter had nothing to do with Ethan, they just needed to stay quietly in the carriage, but when they looked left and right, they found that Rin Tosaka and Leah were not there.

"Where did the two of them go?"

"Looks like you're looking for Hermione?"

Compared to the children who pretend to be children, it is easier for Leah and Rin Tosaka and Hermione, friends who are close in age to play together.

“......”

Ethan pinched his eyebrows, what was originally okay seems to be related now.

I got up and pushed open the door and came to the aisle.

There was no half of the figure in the aisle at this time, and he sensed the location of the two men, and also noticed that a Dementor happened to be approaching the carriage they were in.

"Okay...... It seems that it can't be avoided. ”

Ethan walked briskly over there when he took out his wand, which would be a little more low-key if he used it to cast a spell.

Of course, this was just what he thought he had, and when Ethan came to Harry's carriage and a Dementor was about to rush in and attack Leah, who happened to be blocking Harry, Ethan raised his hand and unleashed the spell that this world was designed to deal with Dementors: Calling God Guard!

A white glow erupted from Ethan's wand, and the dazzling light almost turned the entire carriage into a white world, and the warmth contained in the light directly melted the biting cold chill brought by the Dementors.

This is not the end, after the white light envelops the Dementor in it, it is not the end of forcing the Dementor back, but gradually condenses into a dragon composed of white light, and then let out a roar and opens its mouth to bite the Dementor who is firmly grasped by its claws and cannot move at all.

An eerie scream that shook the soul erupted from the Dementor's mouth, but it couldn't stop the movement of the guardian spirit released by Ethan.

"Eat it!"

As if giving orders to his pet, Ethan's wand erupted in an even more dazzling white light, and the terrifying dementor was torn to pieces by the dragon that had turned into white light and eaten into its stomach.

By this time, Lupin, who was in Harry's carriage, had already woken up, and he had wanted to force the intruding Dementor back, but now he was holding his wand and watching the scene in front of him in amazement.

He felt that all the knowledge about the Dementor in his memory was torn apart by the dragon guardian spirit along with the Dementor in front of him, and he was directly eaten clean.

As for Harry and Ron, they didn't know what this scene meant, only Hermione, the top student, understood a little, and then looked at Ethan, who had released the spell.

"This guy really comes from an ordinary family like me...... And you're just a junior student in my class?"
