Hallie scratched the back of her head in confusion and looked at Zhang Xu, this is the old lady...... No, what's the matter with Lao Tzu?

Zhang Xu thought for a while, and what happened back then was not something that needed to be kept extremely secret, so after thinking about it, he said: "Do you remember when you were a boy, you once met a Dementor in a Quidditch match, and you fell off the broom and were blown away. I got you back. ”

Hallie naturally remembered this, and she was very grateful to Zhang Xu for this, so she ignored some parts of the other party's words.

"Of course I remember, I remember that time you were very badly injured." Hallie nodded and said, "I'm so grateful to you for saving me. ”

(๑>ڡ<): "Why don't you give me a hug when you have a good opportunity now?" ”

(¬′_¬): "Go aside." ”

After teasing Harley, Zhang Xu continued: "That day, I went back to the moment before you were blown away, and then flew with you who was blown away for a while, and finally got you back to the ground. And the injuries on my body were there before that. ”

In the following time, Zhang Xu briefly talked about his experience of using a time turner, but some of the content was still not said.

Then Zhang Xu found that Hallie's spirit suddenly became excited, her breathing became heavy, her neck, face, ears, and eyes turned red from bloodshot, and her hands trembled incessantly.

Zhang's heart shouted pills, and Harley thought of a question that many fandoms often mentioned. What if you used a time turner to go back in time and kill Voldemort, or save Harley's parents?

Zhang Xu just wanted to raise his wand "biu" Harley with a mechanical mind, but who wanted Harley to pounce on him.

Hallie grabbed Zhang Xu's hands and said excitedly, "Then can we go back in time?"

-MP 999

-MP 999

_(´_`」∠)_

Because now Hallie 2.0 is only physically feminine, and her face is only motherized on the basis of Harry, so now Harley not only has the scar on her forehead and the glasses on the bridge of her nose, but also the outline of her face can still see Harry's appearance. Coupled with her terrible line just now, the self-inflicted Zhang received a double critical blow on the spot.

Zhang Xu, whose blood bar was almost emptied, immediately transformed into Zhang Giant Panda, and after breaking free of Harley, he immediately turned back and gave her "biu" a calming spell.

"Sit down, or I'll knock you out now, and then throw you back in the Gryffindor common room while you're still like this!"

After Zhang Xu finished speaking, he thought of what Lu Xun said: "He is about like a Spanish cow, when he sees red, he will get excited and make a terrible action." ”

Harry, who calmed down, was thrilled after listening to Zhang Xu's threat, and then sat down obediently on the stone.

"Time travel adheres to the Novikov principle of self-consistency." Zhang Xu said to Harley very seriously, "People can go back to the past, but they can't change the course of history because of this. You can think of it as the end of our world that has been changed. ”

"If you try to disturb the flow of the river of time, then you are caught in a vortex that time has formed for self-correction."

"For example, if you go back to your father and kill him while he was still at Hogwarts, will you still exist? Or did you kill yourself ten years ago? ”

Zhang Xu then threw a bunch of questions about the paradox of time to Hallie, causing her to fall into deep thought.

Looking at Hallie, who was sitting there and tangled, Zhang Xu picked up a bottle of beer on the ground and drank it himself. He didn't think about it today, he didn't expect Harry's mind to spin so quickly on this issue. Fortunately, Harley can't easily get to the timeturner now, otherwise she would definitely take the timeturner back in time and talk about it recklessly. When the time comes, she'll fold there.

As time went on, not long after Harley turned back into Harry, he seemed to have come to a conclusion.

"So can I just look at it in the dark?" Harry asked, his words filled with bitterness, "I just want to look at my parents. ”

"Because of the Curse of Faithfulness, you can only see their last moments." Zhang Xu said in a deep voice, "I don't think it's a pleasant thing to witness the murder of my parents. ”

"Let me think again." Harry bent down and buried his head between his legs.

At this time, the fire in the pit had become smaller, and Zhang Xu began to backfill the soil and rocks that had been blown up when he was digging the pit just now.

Backfilling may seem like a lot of work, but it's easy with magic.

Zhang Xu only needs to gather the earth and stones on the ground into huge human shapes, control them to run back into the pit, and then release the magic, and the earth and stone people who have lost their magic control will automatically disperse to fill the deep pit.

It's just that digging is a bit troublesome, because it is much easier to gather loose soil into a human shape than to dig up a human shape from solid soil on the ground.

He still remembers a scene he saw when he was a child, in the construction site of the foundation pit, out of the excavator dug out of the mound of earth out of the same size of the earth, they walked into the body of the mud truck neatly lying down, after filling a cart to dissolve the spell. This not only saves the excavator's shift fee, but also facilitates the calculation of the excavated earth and stone.

After burying the slate and covering it with a layer of soil, Zhang Xu saw that a cloud of water vapor came out of the raised mound due to the residual temperature of the underground fire.

He patted Harry, who was still struggling, on the shoulder, and said, "Alright, I'm done with this, it's time to go back." ”

While walking back to Hogwarts Castle, Harry suddenly asked Zhang Xu, "Zhang, how many people have you killed?" ”

Zhang Xu grinned and replied, "Why do you care about this, I can't say the specific number myself." ”

"I see you didn't become a dark wizard for killing people." Harry said as he looked at Zhang Xu carefully.

"Are you afraid you're going to become a dark wizard because you killed someone?" Zhang Xu was relieved of one of Harry's core issues that Harry was struggling with tonight.

Harry's desire was to become an Auror who fought against the forces of evil, and if he had become a Dark Wizard himself, he wouldn't have been able to do that.

After seeing Harry nod, Zhang Xu regained his original momentum again, and said, "The standard of a dark wizard is not just based on how many people kill. ”

Harry, who was walking with his head down, suddenly felt his heart tighten, and then immediately jumped to the side and looked at Zhang Xu vigilantly. At this time, he found that Zhang Xu in front of him was so unfamiliar.
