Of course, Jon has heard of the time converter. After all, this is a prop with a high sense of existence in the original book.

　　 The so-called time converter is actually a device used for time travel. This thing looks like an hourglass hung on a golden necklace.

　　The time converter looks like a small shiny gold timer with a very long and delicate gold chain. Each time the time converter turns, it can go back one hour in time.

　　 The number of times the hourglass is turned, which represents the number of hours back in time.

　　 And in order to be a time converter, the professor must write various letters to the Ministry of Magic, telling them that the owner is a model student and will never use it for anything other than learning... these messy things.

　　 Jon did a few big things with this prop for Miss Hermione Granger in the third grade, so Jon remembered it more clearly.

　　 And even if you don’t talk about the so-called original, Jon had heard the name of this prop from his mother, and had seen what the real prop looked like.

　　 After all, all the time converters are stored in the glass-door cabinet of the Time Hall of the Department of Mystery Affairs of the Ministry of Magic, and Mrs. Smith is a clerk of the Department of Mystery Affairs.

　　 So when he heard this sentence, Jon was still surprised.

　　 "Time converter? Isn't that a lot of things stored in the Ministry of Magic?"

　　 He said: "Since the British Ministry of Magic can store so much, I think there should be a lot in the entire Western magical world, right?"

　　 "Those things that are not defective?"

　　 Perenar snorted: "Time-related magic is very unstable. I don't think I need to say more about this. Serious violations of the time code can also cause disastrous consequences. Everyone is familiar with it.

But those time converters stored by the Ministry of Magic are just consumables and can only be used a certain number of times. Long-term use will cause the converter to fail. The essence is that the materials cannot bear the use of time rules, so they will eventually collapse. Some of the so-called "time converters" that are stored are not even defective products. "

　　 Perenar’s tone was strange, but Jon felt that the witch seemed to simply look down on the time converters guarded by the Ministry of Magic, rather than any other meaning.

What does a defective product mean? Jon knows very well. As great alchemists, it is normal for the Lemays to have obsessive-compulsive disorder. For example, Jon has seen Snape's treatment of potions. Obsessive-compulsive disorder.

　　 Is it possible that every master wizard will have some obsessive-compulsive disorder in the field of expertise?

　　 "Then the time converter you mentioned is a complete time converter?"

Perenar shook his head and said: "The so-called complete time converter is not an alchemy item that a wizard like us can create. It is not an exaggeration to call such a artifact a magical item. Nicol is currently making it. This [Time Converter] is just a bit more complete than the defective products I said. Are you interested in listening to it?"

　　 "Of course, you haven't said how much I helped?"

At this point in time, Jon actually understood some of Perenal’s meaning, and he also roughly figured out where his so-called "help" helped, but now it’s not what he showed himself. time.

　　 Listening is a very good virtue, and Jon has this virtue very much.

　　 It’s good to listen to others' words, especially the elders and elders who talked so much.

　　 Jon never let go of any opportunity to learn and understand.

　　 "In fact, your help is very simple to explain, because you have brought us time."

　　 "Bring...time?"

　　 Jon was a little confused, which was almost the same as he had guessed, but where did the "time" on his body come from?

　　 "The time rule is a very advanced rule of law. Such a rule cannot be used alone in a world. You must have the corresponding strength or the corresponding rule assistance."

"Ok."

　　 Jon nodded, motioning that he was listening.

"When you are shifting time, whether you look back at the past or look at the future-of course, because the future is often uncertain, most people will choose to look at the past and repeat the experience every period of time, but it is just like As I said before, the time converter that the public knows is only a defective product and does not have the ability to modify the timeline."

　　 "No, ma'am, I have seen my mother use the time converter to do something before. If the time converter itself does not have the ability to modify the timeline, how can I explain what I see?"

Jon asked a question "just in time". In fact, he had some guesses about what Perenal said before. After seeing the time converter used with his own eyes, Jon couldn't even remember what was changed~www .lightnovelpub.net~ It just feels that something has changed.

　　 "That's very easy to explain, dear."

Perenal explained to Jon with great interest: "Even if it is a defective time converter, since it can be called this name, it means that it has this related power. I have used one. The better defective products carry out the so-called "time travel", but I am disappointed that it is not real time travel, it just turns part of my soul into a projection, and travels on the preset timeline to do it. Change some established facts, such as the cup in my hand."

Jon watched the cup in Perenal's hand was shattered into powder by the powerful magic power, and then, after Perenal flicked the pocket watch on her chest, Jon saw the cup in her hand. The powder seemed to be turned upside down and turned into a cup again.

"This is the effect of the defective time converter. By modifying the timeline of a small space, some modifications to the timeline in the fixed space are completed, so as to achieve the effect of modifying the time, which is extremely limited. This is why there are so many related prohibitions. If there are no restrictions in this small space, then even a single point may affect the direction of the entire world."

The Butterfly Effect.

　　 Jon nodded to make it clear that he was madly sorting out and summarizing Perenal's words in his mind, for fear of missing something.

　　 This is the first-hand information.

　　 "Nico and I, both of us, started researching time converters a long time ago, but because there are too many regulatory factors involved, it has been unsuccessful until you come."
