"This is amazing~"

Harry Potter also walked into the shell, and naturally followed Ron, the young follower behind him.

In front of the junior, Arthur Weasley deliberately showed off and waved the wand in his hand. Everyone felt that the sky suddenly darkened, and then the shell closed with a loud bang. In front of everyone, it was immediately in a state of being unable to see their fingers.

"Arthur, don't scare the kids!"

Gongsun Zhi's voice sounded again and it didn't make Harry Potter's nervous mood relax. Then a soft white light rose from below, like a small sun rising straight into the sky.

"Buzz~"

The sky seemed to be ignited by this ball of light. The original darkness disappeared and was replaced by a very elegant blue sky and white clouds. The breeze blew by, and for a moment I forgot that this place was in a huge shell, as if it was really in a vast world!

“So amazing ~”

This was the first time Harry had such an in-depth contact with the magic world, especially after being locked up at home for more than a month.

"It's really good. The air circulation is normal, and the magic decoration in the sky is also good. The problem now is that this castle does not seem to require too much magic decoration. However, in order to improve, I think the layout of this castle can be completely based on Hogwarts's!"

Lupin nodded with satisfaction. Although it was the first time for the three of them to build such a huge magic item, it seemed to be very successful. After obtaining Gongsun Zhi's consent, the style of the castle was completely in the style of Hogwarts. Although with the strength of the three people, this castle is still just an empty shell, Gongsun Zhi believes that as long as time allows, it is not impossible to truly turn the shell cabin into Hogwarts.

Then the sky suddenly became transparent. Everyone clearly saw the scene outside the shell. As a tent on the construction site, it was used to climb up and down the escalator, muggle items with magic fluctuations, etc., which were displayed in the air in the slightest.

"Very good, detection magic can perfectly display the outside environment, to prevent you from hiding the shell as a master!

As the shells began to shrink rapidly, the escalators and muggle supplies became larger visible to the naked eye. They did not enlarge again until the shells shrank to the size of a palm. After this several times, make sure that there is no problem.

Later, some functions were tested, such as basic functions such as lifting up and invisibility, and finally, the shell hit the ground, diving, and burning. As a result, neither the magic pattern nor the shell itself received any damage. The three of them were very satisfied with this, especially no matter whether they were attacked by gods and demons, the people inside the shell would receive notifications, but it would not affect the stability of the shell. Even a little change occurred in the sky, the ground did not even stir up a cup of water. This is what Gongsun Zhi was most satisfied with.

"But that's all we can do~"

It was a bit regrettable that Arthur looked at Gongsun Zhi. Time flies so fast at work. Although he doesn't want to admit it, Hogwarts is about to start school in two days. The key is that Gongsun Zhi, as a professor in the Black Magic Defense Class, naturally has to register at the school, so the Shell House can only come to an end. The most important thing is that the Jin Jialong in Gongsun Zhi's hand has almost been spent, and the next royalty will take half a year to settle.

"What a fulfilling and pleasant holiday, but actually, Lupin, you can go to Hogwarts with me!"

It is not a good thing to hide an outsider in the school, but if this matter is allowed by the principal, it is a different matter. Thinking about Lupin's identity, it seems that it is not difficult to allow Dumbledore to enter the school.

"I think Dumbledore shouldn't refuse to have an additional assistant in the Black Magic Defense class!"

"Is this okay?"

Lupin was a little uncertain. After all, he had been running around for so many years to investigate Voldemort and contact werewolf. He knew that last year he only came back after learning that Voldemort returned to Hogwarts. He was a little unconfident in himself for more than ten years, and he was also a werewolf who could be crazy at any time.

"Believe me, Dumbledore will have a solution, and there is no place in this world's most famous potion masters, I'll write a letter right away~"

Just kidding, if this person, who developed according to the normal plot, became a professor in the Black Magic Defense class, not just a teaching assistant, was not discovered after studying for seven years at Hogwarts, but was discovered after learning something. How could it be possible?

Gongsun Zhi was not able to win over, but he went to Hogwarts to learn, but he didn't have time to play the game of cultivating a savior with them. Since the secret room has to be solved anyway, it would be better to clean up the rat called "Spark". Sirius will suffer less than one year of suffering!

"Let's go out too. Today we are going to Diagon Alley to buy textbooks for you to go to school. Speaking of which, as your professor of Black Magic Defense, Lockhart didn't ask you to buy textbooks~"

Arthur Weasley greeted everyone, then waved his wand and flew out lightly. The huge shell then made a small hole, and everyone floated out along the gap. At the same time, everyone's bodies began to grow rapidly and finally returned to normal size.

"Lordhart, with our magical level, we can only accomplish this at the moment, but the big framework has been built for you, and the rest depends on your ability!"

Arthur patted the huge shell and waved his wand. The control that originally attached to the shell immediately dissipated. From then on, Arthur could not enter the Shell Castle without Gongsun Zhi's permission.

"Okay, thank you for your hard work during this period!"

Lupin and several Weasley boys also withdrew their control authority. Gongsun Zhi nodded and thanked. Then the magic wand waved its shell and began to shrink rapidly, and finally turned into the size of a palm and fell into Gongsun Zhi's space bag.

It seems that foreigners do not pay much attention to lunch, but they just ended with some bread sandwiches. The better everyone went to Diagon Alley in the afternoon, Gongsun Zhi also needed to go to Diagon Alley. He said that Gongsun Zhi had a new novel. Although it was just a fairy tale of a wizard, Gongsun Zhi still needed to sign a contract. I believe that his wallet would soon be bulging again.

But before this, there are some things that need to be solved, that is - lesson plan!

I don't seem to be ready to impart knowledge from the students. Although my practical theory was recognized by Dumbledore, there must be a charter for how to practice.

"Lupin, before Dumbledore's reply, I think I have another thing I need your help~"
