Hermione was only worried that Zhou Yu would be questioned by the Ministry of Magic, knowing that Zhou Yu would be fine, she immediately excitedly asked around the phantom shift, phantom shifting is only used by adult wizards, Hogwarts professors naturally do not teach young wizards, and phantom shifting is very dangerous to learn, if you are not careful, some parts of the body may move to the target of the apparition shift, while other parts of the body are still in place, the most common is that the arms and thighs are separated from the body.

For Hermione's curiosity, Zhou Yu gave a detailed explanation, and shared some of his experience with Hermione, the spatial movement spell of phantom shifting is much easier to learn than taking off Thor, but the shortcomings are also very big, it is not suitable for use in battle, and the flexibility is not as good as that of Flying Thor, and the development potential is not as good as it.

I have to say that the two of them came very early, and most of the carriages on the Hogwarts Express were still empty, so they chose a carriage in the middle Zhou Yu and Hermione to do it.

What else can two people who are academic tyrants sit together and talk about? Naturally, it was all related to spells, mainly Hermione asked Zhou Yu for an answer, and the two talked for a long time before Harry and Ron were late.

"Hey, Harry, Ron here." Looking at Harry and Ron, who were looking for the carriage there, Zhou Yu shouted.

"Oh, Yu has to say that it was a wise decision for you to come early, you didn't know that the carriage was full of people." As soon as Ron sat down, he began to speak.

Zhou Yu wisely chose to be a listener.

"Harry, what are you worried about?" Looking at Harry, who had been in a state of worry, Zhou Yu asked.

"Feather, it's ......"

"Ha is a little worried about us in Huaxia dialect, Hogwarts is the safest place in the wizarding world, and with the presence of Professor Dumbledore, Sirius Black can't hurt your Harry at all." Zhou Yu comforted.

The Hogwarts Express drove smoothly towards Hogwarts, and the rainstorm and darkness seemed to indicate that something bad was about to happen.

The Hogwarts Express, which was driving smoothly, stopped after a big earthquake, and many carriages made the sound of luggage colliding, thinking that many young wizards were in trouble, without warning, all the lights went out together, and the little wizards fell into complete darkness in an instant.

"What happened?" Ron was taken aback by the sudden darkness.

"It should be that the car has broken down, after all, it has been running for so many years." Zhou Yu teased in order to ease the atmosphere.

'Fluorescent flashing. Zhou Yu was also not used to the completely dark space, and took out his wand and cast a fluorescent spell.

Looking at Zhou Yu, Harry, Hermione, and Ron also reacted and cast a fluorescent spell.

"Let's go out and have a look."

It was obvious that the little wizards were frightened by this sudden darkness, and many young wizards in the aisle came out to check, Zhou Yu naturally saw a lot of old acquaintances, Neville, Malfoy and his two subordinates, the happiest of which was naturally the Weasley twin brothers, this time is the golden time for mischief, and this time is naturally indispensable for Percy to maintain order in the name of the prefect, but it doesn't seem to be of much use.

The fluorescent spell is not a profound spell, it was just chaos before, but it didn't react, but now that they saw Zhou Yu and the four of them using it, the little wizards naturally took out their wands and cast them.

Under the command of Professor Lupin, the little wizards all returned to their respective carriages, and a cold air suddenly hit, and Zhou Yu knew that the dementors had boarded the train.

The door of the carriage slowly opened, the dementor appeared in the four-person carriage, Zhou Yu also aimed his wand at the dementor, the spell was only to be used for special faces, and the sealing technique was the main force.

The dementor glanced at the four of them and stung Harry, probably wanting to suck Harry's joy and courage, but he was also his friend, how could Zhou Yu allow Harry to be hurt.

'Call the gods to guard. Zhou Yu waved his wand and shouted, a dazzling white light appeared, but Zhou Yu's other hand quietly stretched out the sealing chain, pulling the dementor into his own space, and when he entered the space, he had his own shadow clones to deal with.

Zhou Yu is not worried that the Ministry of Magic will find that there are fewer Dementors, and the Dementors are not undead creatures, and there are still a lot of spells that can be killed, if the Ministry of Magic finds it, Zhou Yu will say that he has been killed by himself, if you don't believe it, you can call one to come over and try it, and if you want to come to the Dementor riot and attack the students, the Ministry of Magic does not dare to spread it around, not every little wizard's parents are good-tempered.

Zhou Yu's big movement in the carriage also attracted Professor Lupin's attention, and seeing that no students were injured, especially Harry, they were all safe and sound, Professor Lupin left with peace of mind.

The Dementors retreated, and the Hogwarts Express restarted.

Another year of freshmen arrived, the Sorting Hat quickly assigned the academy to the freshmen, and Hagrid also became the new professor of magical biology to protect it, I have to say that Hagrid is very suitable for such a subject, but people are a little unreliable, and the first class allows the little wizards to come into contact with the highly dangerous and ferocious predators of the eagle horse.

After the banquet, Professor McGonagall found Zhou Yu and Hermione, and after Professor McGonagall's office entered, Zhou Yu found two shiny gold timers on the table, third year? Zhou Yu seems to know what those two are, the time turner, can go back to something a few hours ago, I have to say that there are still many surprises in the wizarding world, Zhou Yu became interested in ancient wizards at this time, and this very magical magic item like time can be refined, it's not easy!

Professor McGonagall sternly explained to the two of them the various things to pay attention to in the time turner, and they should not use it indiscriminately except for studying, and then let the two go.

Zhou Yu and Hermione also excitedly took the time turner back.

Sure enough, the matter of the Dementors was not so easy to pass, but it was not the people from the Ministry of Magic who came to find Zhou Yu, but Dumbledore who found Zhou Yu.

Dumbledore seemed to know that Zhou Yu had done something to the Dementors in order to help Harry, and as for raising the Dementors, even the evil Dark Wizard would not do this, and Dumbledore naturally wouldn't let him think about it.

Dumbledore didn't do much about Zhou Yu, and let Zhou Yu go back after a gentle lecture.

On the way back to the dormitory, Zhou Yu calculated his own little abacus, he came to Hogwarts for the third year, and the wizarding system was also learned very deeply, not Zhou Yu was arrogant, Zhou Yu was sure that many professors were not necessarily better than him, Zhou Yu had ten times the learning efficiency environment and shadow clone cheating, and time would not be the reason for hindering Zhou Yu's growth at all.

The only thing that attracts Hogwarts right now is the forbidden book section and the luck of following Harry's mixed appearances, but these are not enough to keep him in Hogwarts.
