Time began to reverse, Zhang Xuan only saw that the surrounding scenery was also constantly regressing, and suddenly the time flow stopped, Zhang Xuan felt his head sink, and then came to his senses.

Zhang Xuan hurriedly took Hermione to the side and watched him and Hermione reading.

Hermione was also curious, looking around at herself and the surrounding scenery.

Zhang Xuanxin said, I am so sharp, it is normal not to find myself as a person with astringent breath, but why hasn't I discovered the breath of Hermione, an ordinary person?

I didn't find more than one person in my memory.

"Alright, it's time!" Hermione and Zhang Xuan waited until an hour had passed before turning the time turner and taking them back to an hour later.

Zhang Xuan's memory has the memory of going back to the past hour, and the bite wound has healed slightly.

"We really made it!" Hermione laughed, "The time turner really works!" ”

Zhang Xuan also smiled: "It's really amazing!" Time is such a thing, the two of us have surpassed it! ”

After going back to the hall with Hermione and the others for dinner, Zhang Xuan returned to the dormitory.

"I go back in time, and the hour I was there at the same time as the current me, but if I had reminded me not to bite my lip an hour ago, would I be without a wound now?"

"If I went back in time and spent an hour, why would the time turner have to go back another hour? Doesn't the time turner go back an hour ago? ”

"Or are we going to only one time branch, and then take this change back to the current world, in the original side world I have disappeared or the side time no longer exists?"

Zhang Xuan preliminarily judged several ideas, and was going to find some information first, and then try the time turner to see how it worked!

So Zhang Xuan wrote a few notes by hand, and then the next time he went to travel time with Hermione, he secretly stuffed the notes to himself.

On this day, after everyone was led into the ranch forest in Shanghai's Fantastic Beasts class, Hagrid pointed to a winged horse with the head of an eagle and said:

"This eagle-headed winged horse is called Buckbeak, and it pays great attention to etiquette! If you want to ride it, you have to bend down and salute, and if it nods, you can ride it! ”

Zhang Xuan was indeed very strange when he saw this Buckbeek, and his eyes flashed like a child.

"Does anyone want to try it?" Hagrid shouted, but no one answered, so Hagrid called his favorite Harry, "Harry, come!" ”

"Me?" Harry was a little unconvinced.

His self-confidence had been shattered by the Dementors these days, and the Dementors all over the school had terrified him like a mouse.

"Yes!" Hagrid laughed, "Walk over slowly, then bend down and salute!" ”

Harry did as Hagrid said, and Buckbeak nodded.

Looking at Harry who was riding Buckbeak and cheering, Zhang Xuan's heart was happy, when Harry was low, he happened to meet Buckbeak to restore his self-confidence?

If it weren't for Dumbledore's instructions, Hagrid would have been so meticulous?

Why did the Defence Against the Dark Arts class happen to Lupin to teach?

Didn't Dumbledore know that Lupin was a werewolf?

Don't know the relationship between Lupin and Harry?

Would Dumbledore, with his crystal ball and live point map, not know that Sirius Black was hiding in a secret room under the beating willows?

Zhang Xuan didn't believe it.

When Harry came down from the sky with an excited face, Draco Malfoy looked angry.

In the past few days, he had admired Harry's panic and ugliness, and when he saw Harry regain his spirits, he said angrily:

"I know Buckbeak isn't dangerous at all! It's all Hagrid, you scare people! You brute, why don't you bend down and let me ride it! ”

Draco's actions visibly infuriated Buckbeak, who let out a roar and kicked Draco down in an instant,

"Ahh My hand! Draco yelled!

Seeing this, Zhang Xuan hurriedly stepped forward and waved his wand and said, "Stop the bleeding from the wound!" ”

Draco's arm stopped bleeding.

"Professor Hagrid, I'm going to take Draco to the infirmary, his bones may be hurt!" Zhang Xuan said with a smile.

"Okay! Go find Miss Mary to have a look! Don't leave anything to chance! Hagrid nodded, and Zhang Xuan hurriedly took Draco to the infirmary.

"Thank you Zhang Xuan!" Draco was grateful.

Zhang Xuan smiled: "You're welcome! We're all classmates! ”

As he spoke, Zhang Xuan made a thin cut on Draco's clothes.

After returning from the infirmary, Zhang Xuan carved another mark on the tree, and then returned to the classroom.

"Hermione, what did you just go on? Can you let me watch Hagrid's class go through later? Zhang Xuan said in a low voice.

"Okay!" Hermione nodded hurriedly, she was responsive to her boyfriend's request.

After class, the two of them went back to an hour ago.

Seeing that he had sent Malfoy back to the infirmary, Zhang Xuan hurriedly threw a note over.

"What are you doing?" Hermione whispered.

Zhang Xuan said: "It's just a small experiment!" ”

When the class was over, Hermione turned the time turner, and the two returned.

As soon as Zhang Xuan touched his pocket, he found a note.

I went and looked at the marks made on the tree, but there was nothing on it.

"It looks like I picked up the note and followed it, without marking it on the tree!" Zhang Xuan muttered:

"But I don't have the memory of picking up the note, which is weird!"

"I went back to the past and changed my actions, but I went back to the present without any memory of that time, only the memory of my own time travel!"

Zhang Xuan muttered: "That is, I just went to another parallel world, and then I just brought back the results of the parallel world after the change!" ”

However, this is still just speculation, and Zhang Xuan followed Hermione to time travel a few times after that.

After a series of comparative tests, Zhang Xuan found that going back to the past is equivalent to going to other parallel worlds to rob, and the result of the robbery is the fact that you have changed.

And when you travel in time, the physical time will not go back to the past, and in the process of traveling between positive and negative, you actually spend twice as much time.

To go back to the world an hour ago, you have to spend an hour changing or not changing things, and then use the time turner to go back to the original world an hour later.

Then the facts that change or don't change replace the facts of the original world, and a time robbery is completed.

So you won't have memories of that time. Because you in the parallel world are not the same person as you in the original world.

By the time Zhang Xuan figured it out, the semester was almost over, and Zhang Xuan and Hermione had grown faster because they used the time turner to have a few hours more than others every day.
