"Professor Lohart, Lupin Assistant Teaching, Good morning~"

As expected by Gongsun Zhi, he received a reply from Dumbledore not long after a letter of recommendation was sent. Not only did he agree to Lupin as an assistant coach in the Black Magic Defense Class, but also took into account the opinions on actual magic warfare proposed by Gongsun Zhi, and specially established a duel club. It was also stipulated that the duel club can apply for a classroom at Hogwarts as the venue every Wednesday, and appointed Gongsun Zhi as the director of the duel club. Lupin is also an assistant, and at the same time allowed Gongsun Zhi to invite deans and professors from major colleges as club mentors, etc.

"Hermione, sit down~"

There is a special lounge for professors on the Hogwarts Express, but neither of them cares very much. Compared with the more spacious teacher area, the two prefer to get along with the students.

"Hello, two professors, I am Neville, Neville Longbottom!"

The little fat man was very shy, but Gongsun Zhi took a look at this person with a high look. He was recognized by Gryffindor and finally pulled out the Gryffindor sword and killed Voldemort's soul weapon. Although he is a little immature now, he is a person who can make a perfect counterattack after all, and should not be underestimated!

"Hello, Mr. Longbottom~"

Well, Gongsun Zhi and Longbottom’s parents are not familiar with each other, they only know that the other party is a powerful Auror, and they are also tortured by Voldemort because of Longbottom’s date of birth. By the way, if there was no accident in the predecessor, it seemed that he would have been with Longbottom and his wife in the end!

"Professor, have you seen Ron and Harry?"

The train swayed and then began to exercise, when Hermione suddenly asked.

“No~”

Gongsun Zhi shook his head and then looked at Lu Ping.

"I didn't see you. Before getting on the bus, I saw two boys outside the platform. Didn't they come up?"

Lupin frowned and keenly discovered that something might have happened.

Gongsun Zhi naturally knew what was going on. Before, Gongsun Zhi originally planned to buy a house-raising elf, but after thinking about how many years later, Gongsun Zhi's intention to buy an elf was faded a lot. Even in perfect magic, there were loopholes. Elfs, a creature that has been domesticated for hundreds of years, can still get loopholes in the magic contract. What Gongsun Zhi has to do next requires a certain degree of confidentiality, so he will naturally not leave a time bomb around him!

"What is that?"

Longbottom suddenly looked out the window, and his face showed extremely exaggerated horror.

"Um?"

The three of them turned around and saw a yellow sedan suddenly appearing in the horizon outside the window. Obviously, the driving skills of the people driving were not very good. At this time, the sedan was swaying up and down, swaying from side to side, and it was sometimes close to Hogwarts' express. However, it was precisely this important task that soon discovered that the driver of the sedan was unusual.

"It's Ron and Harry~"

"Potter?"

Hermione and Lupin exclaimed one after another, not knowing if the sound was too loud and that Harry Potter outside heard it. Then he looked over and showed a look of surprise.

"Professor, save us quickly, help us~"

Harry Potter held the seat in the car with both hands, but he did not delay calling for help.

"This car is Arthur's proud work. It can not only fly in the air but also has high intelligence. The most important thing is that it has strong defense. If we do it rashly, it will easily have a counterproductive effect!"

Lupin took out his magic wand, but after opening the train window, he stopped two more. He seemed to have no way to save the two.

"Professor quickly think of some solutions, and you're going to enter the tunnel ahead!"

Hermione has been observing the direction of the expressway, and after discovering the black hole in front, she quickly reminded her.

"Maybe there is a way!"

Gongsun Zhi picked up the decorative shell from his waist, and then threw it out without hesitation.

"Recovery as before~get bigger quickly~"

The small shell, originally the size of a palm, instantly turned into three meters in size and then continued to grow bigger. It turned into a giant hundreds of meters in size before stopping.

"Buzz~"

The shell slightly opened and revealed the magnificent world inside, and a huge castle faintly appeared.

"Swoosh~"

Ron's three-no driving skills naturally could not escape the shell, and drove directly into the shell in the car.

"Bang~"

"Shell Castle is here~"

Swallowed the car into the shell, Gongsun Zhi waved the shell and turned it into the size of a palm again, and finally fell into Gongsun Zhi's hands.

"Bang, bang..."

The moment the car window closed, the car where Gongsun Zhi was located drove into the tunnel.

“So awesome ~”

"What was that just now?"

"Is it a new magical creature?"

"It's obviously a mountain~"

"Nonsense, I saw that it was obviously a big mouth..."

Many students in the Hogwarts Express saw the scene of the shell opening their mouths, and for a moment the entire express became extremely noisy. Some sharp-eyed students even noticed that the shell seemed to have entered the express.

"Tell me, Gryffindor's Lion~"

Gongsun Zhi placed the shell on the table, then waved his wand to open the shell, a pocket space was displayed in the top paint of everyone, and inside the tight space of the shell, a yellow sedan was lying quietly on the hard inner wall of the shell, and Harry Potter and Ron fell limply on the Guanghua ground.

"Well, professor, we don't know why. We originally wanted to enter the platform, but we didn't know why the platform seemed to be closed. For this reason, we were both injured~"

Harry quickly explained.

"Yes, professor, we have no choice but to drive the car and chase the express~"

Ron, who was beside him, also replied in a low voice.

"So, why didn't you think about writing to us to let the professor solve this problem? Have you ever been discovered by Muggles while driving a car?"

Lu Ping originally planned to praise him, but as soon as he opened his mouth, he was interrupted by Gongsun Zhi.

Gongsun Zhi has never understood why students do not want to find teachers or parents after encountering difficulties. Even for people like Voldemort who harm the entire magic world, the Harry trio did not think about notifying the principal, but instead solved it with hope. Are these children really so envious?

“Uh~”

The two of them looked at the four people who looked like giants and stared at them. After hearing Gongsun Zhi’s question, they couldn’t help but hesitate. After a long time, they spoke!

"Sorry, professor, we know we were wrong!"

Indeed, what Gongsun Zhi said was the safest solution. After all, it was too dangerous to fly in the sky just now. If Gongsun Zhi didn't know that he used shells to bring them in, the two of them might have bumped into the cliff to see Meilin.

Of course, the two of them didn't know that even without Gongsun Zhi's help, they wouldn't have any trouble, but this car seemed to be beaten by Liu Bobiao.
