The corners of the corridor disappeared, and Tom could feel himself flying backwards rapidly, and everything around him turned into mosaic-like shapes and colors. The flying speed was so fast that his eardrums were a little swollen——
Fortunately, this feeling only lasted a short time. Tom's feet touched the solid ground and everything became clear again. Tom and Hermione were standing in front of a portrait. Next to the portrait was the stairs leading to the north tower.
.
Tom could feel that the golden chain of the time turner had been cut into the flesh of his neck, but before he could do anything extra, he and Hermione ran into the narrow spiral staircase.
The next second, they heard such a conversation.
"—I think it's this way over here." Tom's voice came from outside.
Then Hermione's voice rang out: "I don't think so. Look, you can see a little bit of the lake outside the window, so this is the south side of the castle... We are going to the north tower."
Tom knew that in a few seconds they would find the staircase.
This feeling is very magical: I am inside the stairs and outside the stairs at the same time. A straight line turns around and intersects with the past point.
"Hurry!" Hermione's face turned a little pale, "We can't let our past selves see it!"
Tom led Hermione and ran upstairs.
The noise they made when they moved alerted Tom and Hermione outside. They followed and discovered the staircase.
"My intuition tells me that this is the staircase leading to the North Tower..." Tom in the past said standing at the top of the stairs. However, although he found the entrance, he did not rush in. Instead, he carefully looked around at the entrance for a while.
before walking in.
At this time, Tom had already run to a small window in the tower. He turned into a phoenix, jumped out of the window with Hermione, and then landed lightly on the ground.
"Arithmetic?" Tom took off the gold chain of the time turner from his neck and looked at Hermione to ask for her opinion.
Hermione rolled her eyes, ignored him, walked half a circle around the castle, and walked into the foyer from the main entrance. At this time, the foyer had become empty, and a beam of golden sunlight shone through the outside glass window.
On the marble floor, Hermione happened to be standing under this beam of sunlight. The bright light cast a shadow on her face, making her facial features more three-dimensional.
She still didn't want to pay attention to Tom, and seemed to be still in a mood.
She walked in front, and Tom followed.
"What can I do to calm you down?" He took Hermione's hand and the two of them stopped in front of the stairs in the hall.
Hermione turned to look at him.
Tom came closer and put the balled-up black socks into the pocket of Hermione's robe, "I was wrong in the Divination class..."
Hermione finally had a smile on her face, her left hand gently placed on Tom's ear, then she came closer and touched his lips like a dragonfly touching water.
Tom's eyes got bigger and he felt like he was okay again.
"Have you forgiven me?"
Hermione opened her eyes wide and shook her head very cutely, "It's just a reward for good children who correct their mistakes after they realize they are wrong."
She turned around, ran two steps like a bird, then turned to look at Tom, "Next time, you have to put it on for me!"
As she said that, she sat on the stairs and put her black stockings back on.
"——If you don't hurry up, you'll be late." When Hermione changed her socks and put on her shoes, a gentle voice came from their heads.
It's Dumbledore again.
At this time, he was standing on the stairs of the second floor looking down with a smile on his face.
Old bee! Tom cursed secretly in his mind, pulled Hermione, who was already blushing, and ran towards the arithmetic and divination classroom.
The teacher of this course is Professor Setima Victor.
Arithmetic divination refers to a kind of divination that uses numbers to explain a person's character and destiny, or to predict the future. It can also be called "numerology". It is similar to reading crystal balls, tea leaves or palmistry, etc. based on vague interpretations
It is different from traditional divination which uses images, or deduces the inner meaning of things from random graphics or random words. Arithmancy is based on a series of rules and rigorous mathematical operations. Arithmancy in the magical world is based on Kabbalah.
Established based on knowledge of Pythagorean philosophy. They reduced the sum of all letters to numerical values from 1 to 9 for use in divination.
For Hermione, this kind of subject that requires strict logical thinking is very attractive.
"8:57." When Tom arrived outside the empty arithmetic and divination classroom, he took a special look at the time - thanks to Professor Trelawney, she did not delay the class, but ended the get out of class a lot earlier.
If she stays in get out of class until 10 o'clock, then Tom will be in trouble. Because one rotation of the hourglass goes back to one hour ago, Tom and Hermione must be cautious, because after the time goes back, they will not stay in the same place. Instead, they will return to where they were an hour ago.
This requires time-travelers to be very, very careful and cautious. They must remember when they were in a secluded environment. Don't go back and find themselves standing in the auditorium and being seen by all the teachers and students of the school - that would be the end.
But here's the good news: As long as this doesn't happen, it won't happen.
This sentence may sound like nonsense, but it can very intuitively explain various problems that arise in time retrieval: that is, the facts observed by the time retreader cannot be changed.
In other words, what Tom and Hermione saw in the past will definitely happen. Tom and Hermione can do things in places that are beyond their sight, but as long as they are seen in the past, nothing can be changed.
For example, in the past, Tom and Hermione saw a reindeer lying dead on the edge of the Black Lake. No matter how hard they try in the future, a reindeer will definitely fall dead on the edge of the Black Lake.
Because this is an established fact and cannot be changed.
Even if Tom and Hermione saved the world during the flashback, there was no way to change the fact that a deer fell by the lake.
What's even worse is that the more detailed they are about the details, the harder it is to change the facts.
Let's take the reindeer example again. If Tom wants to save the deer, he can turn into a deer himself and fall down by the lake - recreating the scene he saw before.
But if Tom and Hermione confirmed the death of the reindeer before, then Tom would have to find a deer carcass and put it there to fool them.
Playing tricks in an unknown space is the key to time retrieval.
Tom and Hermione pushed open the classroom door and walked in. Before entering, Tom glanced at a broom cupboard in the corner of the corridor and smiled.
