Mysterious Walker at Hogwarts

"That's right, that treacherous guy!" Tertius said angrily.

"It's normal. Goblins have always been hostile to wizards." The Mysterious Walker was not surprised by Ragnor's behavior.

"Mr. Mysterious Walker, can you please take us out of here?" Bill asked tentatively.

"Mr. Weasley, you should know that there is no free lunch in the world. Instead of begging me, you should find a way out on your own." The Mysterious Walker declined politely.

"I'm afraid we don't have the ability to return the way we came." Tertius said with shame.

"I can show you a way. As for whether you can get out, it's up to you." The Mysterious Walker said.

"We're willing to give it a try."

"Very good. If you can escape smoothly, in return, please don't reveal that you have seen me here." The Mysterious Walker said.

"no problem!"

"Very good, I hope you won't betray my trust - where the insect corpses are densest over there, there is a trap door below. You can try your luck, but remember you can only move forward, not backward!" the Mysterious Walker pointed out. Pointing to a corner of the treasure room.

Tertius and Bill ran over immediately.

"Tornado sweep away!" The two shouted at the same time. After the insect corpses were cleaned up, a trap door was indeed revealed.

"Mr. Mysterious Walker, there really is a door!" The two excitedly turned around, only to see the silver light flash out, and the mysterious Walker had disappeared from the place.

……

"Huh! Fortunately, I went back!" After returning to his true self, Dean let out a sigh of relief while lying on the hospital bed. Just now, he was once again pretending to be the Mysterious Walker to guide Bill and Tertius.

"Dean, why did you use the time and space converter again?" Rolf asked from the bed next to him.

"To discover the magical uses of the alarm clock, of course you have to experience it." Dean explained, "You haven't fallen asleep yet?"

"I still want to remind you that things like this that may disrupt time and space should be used with caution." Rolf turned over and soon began to snore.

As for Ron, he was already asleep in another hospital bed.

After a night of thrilling adventure, all their energy had been exhausted.

Dean was too excited to sleep.

When he ended the teleportation state while holding the silver bottle, he found that he was back in the ward of the Hogwarts campus hospital. Rolf and Ron were looking at him with worried eyes.

It seemed that it was still late at night outside the window, instead of the expected daylight.

"Dean, you are okay, that's great." Seeing that Dean was "vomited" out of the black hole safely, Rolf let out a long breath.

"What time is it now? Why is it not dawn yet?" Dean asked in surprise, "Didn't Madam Pomfrey do her rounds?"

"You can't guess that it's only five minutes after ten in the evening!" Ron exclaimed in a tone similar to an aria, "It's only been five minutes since we were sucked into the black hole before!"

"What's going on?" Dean looked at them with a question mark on his face.

"Dean, I think you have a great treasure." Rolf handed the silver alarm clock back to Dean and said, "If I'm not mistaken, this alarm clock is actually a time and space converter."

"Time and space converter? Are you sure it's not a time converter?" Dean confirmed. Although there was only one word difference, the difference was huge.

"I'm sure." Rolf stretched out his hand and quickly pressed the small bump on the alarm clock cap three times. The originally ordinary alarm clock immediately underwent an incredible change: the dial popped up, revealing a complex and complex hidden behind it. Precision mechanical-like structure.

Bursts of mysterious silver light flow inside the alarm clock. Every slender spring, every delicate gear, and every cleverly conceived spring exudes all kinds of fascinating magic. There is no doubt that this is a magical and magical place. A masterpiece of mechanical combination.

"Did you see it? These pointers represent the year, month, day, and time respectively. These adjustable numbers represent the coordinates. If you want to go to a specified time and place, just put Align the hands and transcoding to the corresponding time and coordinates, and then press the dial back to its original position, and the time-space converter will take effect." Rolf introduced in detail.

迪安注意到现在闹钟内部的指针所指的时间，正是1992年2月6日22点05分——刚刚他传送回来的那个时间点。

As for the code that represents the geographical location, it is a series of numbers with unknown meaning, which should represent the coordinates of Hogwarts. Dean secretly remembered it in his heart.

"Rolfe, you researched all this in just a few minutes in your pocket?" Dean asked in disbelief.

If his memory is correct, the time he spent fighting the sacred beetle did not exceed 10 minutes at most. In other words, Rolf only used this little time to find out the secret that Dean had not discovered for 11 years. It was almost shocking to Dean. No place to be ashamed of.

"No, in fact, this is all the result of my grown-up Sniffing Sniff. After it accidentally discovered the secret of the alarm clock, it has been experimenting with this thing recently. When it was in my pocket just now, I snatched the alarm clock back and put it in my pocket. Under Hobi's threat, he demonstrated it to me." Rolf said, half surprised and half proud, "After I learned how to use this time and space converter, I immediately tested it and successfully brought us back to this time and space. .”

Ron was a little confused when he heard it, but he still tried to understand: "In other words, although we are safe now, there is actually another one who is exploring the mysterious pyramid at the moment?"

"Theoretically, that's the case. It's precisely because we have returned safely without being discovered by anyone that no one will go to the pyramid to rescue us." Dean replied.

"What would happen if the two of us met?" Ron asked curiously.

"It is easy to have the tragedy of killing yourself, so the time and space converter must be used with caution, or even better not to be used!" Rolf warned seriously.

"Hey, buddy, don't look at me with that dangerous look. Anyway, the owner of the time-space converter is Dean, and I'm unlikely to have the chance to use it." Ron was frightened by Rolf's eyes.

"Dean?" Rolf looked at Dean.

"I promise that even if I use it, I will only use it where it has to be used." Dean's promise was a bit perfunctory.

"Okay, this is your thing." Rolf was not very satisfied with Dean's answer, but he could do nothing about it. "I hope everyone will keep the matter of the time and space converter a secret. If it is leaked, it will bring trouble to us, especially Dean." Bring disaster.”

"Of course, I'm not stupid!" Dean rolled his eyes at Rolf.

"B-But I'm afraid of accidentally revealing it. You know I have the habit of talking in my sleep." Ron said cowardly, "Maybe you should use a forgetting spell on me."

"Don't be stupid Ron, do you think we will cast a forgetting spell on our friends just to keep the secret?" Dean patted Ron on the shoulder, "We believe you, as long as you don't deliberately leak it."

"I promise!" Ron was so moved that he almost cried.

Dean was pleasantly surprised to find that Ron's favorability level had increased a lot!
