Ethan will no longer pay attention to sending Shirou Emiya and Artoria to that world.

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

Before departure, Shirou Emiya and Artoria were already familiar with the various equipment on the Moon Goddess, including storage props and armor and a series of weapons, especially how to call Luna when it is critical.

If an accident occurs, Luna can teleport them back to the ship. After all, this is just a training to improve Emiya Shiro's strength, rather than really pushing him to the battlefield and die.

"I wonder if Shirou Emiya can understand the principles of those sets of armor and copy them..."

Shiro Emiya can project shields and armor, but the duration is not as long as the weapon, and it consumes more magic power.

But now Shiro Emiya has embarked on a completely different path. The projection magic he has learned and mastered now is already very different from the magic that Emia uses. It can even be said that Shiro Emiya mastered the projection magic that Shiro Emiya is closer to the chaos magic that Tony taught to the Scarlet Witch, but the type of "created" items is relatively single.

"After working hard, it's time to go back to study?"

"It doesn't matter if you don't go, right?" Rin Tosaka looked around. She might be the only one in it who went to Hogwarts to study seriously. Ilia and Leya might also be studying hard.

The rest are like Scaha, Logan, and Ethan. Essence is essentially going there for vacations, and even studying is just by the way: "Even if you used to learn magic knowledge in that world at the beginning, you should have learned almost the same thing now."

Ordinary students can't see the tacit understanding between Dumbledore and Snape and Ethan, but these people are still very clear, because they can easily get more knowledge from Ethan to learn from the knowledge that they can only learn from seniors.

"There is one thing I need to study, and after that... there is really nothing to do."

While chatting, several people came to Harry Potter's world again.

"Time converter?"

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

In addition to teaching Shirou Emiya, Ethan was studying the power of time during this period and often tinkered with a bunch of monsters and flesh that he had made from unknown worlds. Occasionally, he was easily scared when he was doing experiments, as if he was a madman doing some evil experiments.

“Yes, the time converter.”

In fact, last semester, he could get this prop through Snape's relationship, because this thing is not a special prop with "only one" in the Harry Potter world, but a lot of them were later destroyed.

It can be said that if those bunch of time converters were not destroyed, then no matter what happened later, they could be saved through these plug-ins and props. However, in that case, the story of Harry Potter might have to be changed to the Flash.

But last semester, Ethan still had a lot of knowledge to learn, so he pushed the time converter slightly. Anyway, there is no hurry to get this thing for the time being, so it doesn't matter if you get it later.

Besides, he knew that even if he didn't take the initiative to ask for this prop, Hermione should have already obtained this plug-in from Professor McGonagall, and then enrolled in all the elective courses in the new semester, as if he was a top student to the end.

"How to solve your physical appearance problem?"

"Just use illusion to deal with it."

Ethan's body cannot be said to have not grown at all. After absorbing some of the energy of the Shadow Country, he can usually extract energy from the magic dimension. He even found that magic stones can be eaten as snacks and can be replenished into his body, his body has also developed a little.

But compared to ordinary people, the development speed is very slow... If his body was just transformed into a divine body, he looked like he was in his early 10s, and after so long, he is now over eleven years old and less than twelve years old.

Fortunately, Ethan's body is tall among the same age, and it is not too eye-catching 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 and got the course schedule for the new school year. I went to Diagon Alley to buy the books and tools I needed. All of this went smoothly.

The Harry Potter World was very peaceful in the first few years of the plot. Although Voldemort's loyal subordinates were secretly engaged in some conspiracies, basically what happened was just the "child" and there was no major disaster that could endanger the world's security.

So as long as you don't get close to the protagonist Harry Potter, for Ethan and the others, this is a peaceful world where magic exists, and they can teach in a school where magic is taught.

Even if you get close to Harry Potter and get mixed up with the plot, the trouble you encounter is not much and can be solved easily.

However, things became a little bad from the next few years. The conspiracy around Harry was involved in a wider range, and more and more people were involved. Moreover, the identities of these people were becoming more and more diverse, especially the chaos within the Ministry of Magic, which led to many things being clearly understood, but were very troublesome by a group of pig teammates.

This was nothing to do with Ethan. According to his plan, he was able to learn all the knowledge he wanted to learn in the past two years. If he didn't help, he could copy it to his magic book first, and then study it slowly after he went back.

But the Ministry of Magic's stupid behavior really made Ethan speechless because Sirius: Sirius Olein Black escaped from Azkaban. In order to hunt Sirius and consider the relationship between this man and Harry Potter, the Ministry of Magic arranged a large group of dementors on the periphery of Hogwarts under the pretext of protecting the young children in Hogwarts.

The train had just entered the dementor's defense circle, and Ethan and his group sensed the breath of these magical creatures.

"It's such an unpleasant atmosphere."

Dementor is a magical creature that looks like a ghost. Ethan immediately notices that Dementor is a pure energy aggregate, and its energy attributes tend to be negative. Because it is an energy creature, it is almost impossible to be killed in this world. The common way to deal with Dementors is to urge the gods to guard the defensive spell.

"I'm actually quite curious if the Dementor really killed several students, how should the Ministry of Magic explain it?"

It would be amazing to throw a group of completely uncontrolled magic creatures near the school, even to capture Sirius, to do such behavior.

Just as Ethan was speechless about the development of the matter, the train suddenly stopped.

If you remember correctly, the next scene should be in the plot: Harry Potter was attacked by the dementors, and Professor Lupin, who happened to rest in the car, took action to repel the dementors and rescued Harry Potter. So Harry later wanted to find Professor Lupin to learn how to deal with the dementors.

"Several people came into the train."

This matter had nothing to do with Ethan and the others. They just needed to stay quietly in the car, but after looking around, I found that Rin Tosaka and Lea were not there.

"Where did the two of them go?"

"It seems like I'm going to find Hermione?"

Compared to these people who pretend to be children, Lea, Rin Tosaka and Hermione, who are really close to each other, is easier to play together.

“…”

Ethan pinched his eyebrows. It seemed that something that was okay was already related.

He got up and pushed open the car door and came to the aisle.

At this time, there was no figure in the aisle. He sensed the location of the two people and also found that a dementor happened to be approaching the carriage where they were.

"Okay...it seems that I can't avoid it."

When Ethan quickly walked over there, he took out his wand and would look a little low-key if he casts a spell with his wand.

Of course this was just what he thought. When Ethan came to the carriage where Harry and the others were in, a dementor was about to rush in and attack Lea who happened to block Harry, Ethan raised his hand and released the spell specifically used by this world to deal with Dementors: the God Guard!

A white light gushed out from Ethan's wand, and the dazzling light almost turned the entire car into a white world. The warmth contained in the light directly melted the biting cold chill brought by the dementor.

This is not the end. After the white light enveloped the dementor, it was not the end to force the dementor back, but gradually condensed into a giant dragon composed of white light. Then, it roared and opened its mouth and bit it at the dementor, which was firmly grasped by both claws and could not move at all.

A strange scream of trembling soul erupted from the dementor's mouth, but this could not stop the guardian spirit released by Ethan.

"Eat it!"

As if he was ordering his pet, the magic wand in Ethan's hand burst out with a more dazzling white light, and then the terrifying dementor was torn into pieces by the giant dragon turned into white light and eaten into his stomach.

At this time, Lupin in Harry's carriage had already woken up. He had originally wanted to force the dementor to retreat, but now he held his magic wand and stared at the scene in front of him in a daze.

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 ate it clean.

As for Harry and Ron, they had no idea what the scene in front of them meant. Only the academic master Hermione understood a little, and then looked at Ethan who released the spell.
