——Time exists objectively.

——Time is asymmetrical in the magic dimension.

The tip of the quill in Zheng Qing's hand was pointed at these two conclusions. He felt that there was an idea in his mind, which was just a little bit close to being perfected, but it seemed to be blocked by a thin and tough film and could never come out.

After all, he has only been exposed to the wizarding world for more than a year. Although he has performed well, his foundation is not very solid after all. Many common senses that young wizards from aristocratic families are familiar with are somewhat unfamiliar to him, so it is difficult to draw parallels and inspire inspiration.

Since he couldn't understand it all, he had to find a "stone from another mountain".

Stones from other hills, can learn.

The best piece of stone that Zheng Qing thought of was Su Shijun's two-dimensional evolution experiment - projecting the phenomena of the high-dimensional world into the low-dimensional world, and then referring to the accumulated experience in the low-dimensional world to help understand the changes in the high-dimensional world - this kind of Experimental ideas can actually be applied in many places.

Like now.

While the tip of his pen was lingering on those two conclusions, a very appropriate 'reference' already appeared in Zheng Qing's mind - movies. To be precise, it is a movie played on a computer player.

For people in the real world, movies are definitely a two-dimensional world.

In this two-dimensional world, time exists objectively, and its existence is manifested by the progress bar on the player. Within the scope of the movie's time and space, everything is certain - from the beginning to the end of the movie, every frame , every dialogue, every scene is certain - for movies, time and space are very real existences, they are just extensions of different dimensions in different directions, and there is no difference in essence.

From this perspective, the two-dimensional world is indeed easier to understand the true meaning of the so-called ‘objective existence of time’ than the high-dimensional world.

As for the asymmetry of time in the magical dimension, the performance is relatively obscure, but it is not difficult to find - for example, the passage of time in movies has the characteristic of natural 'one-way movement'; the left and right sides of the player's progress bar are naturally asymmetrical ;A new movie's past (under natural conditions) is observable, its future is unobservable; and so on.

Also, each character in the movie experiences a different 'time flow'. All time is spent developing around the 'most important' character, while unimportant characters sometimes don't even get a frame.

With this 'stone', Zheng Qing rethinks the concept of 'time conversion', and the situation becomes very clear. He only needs to drag the slider on the progress bar from the right to any time node he wants to go to the left, and the time will be reset.

Compared to movies, the mouse dragging the progress bar slider outside the screen is the power from a ‘higher dimension’.

In the real world, there is no mouse arrow hovering over the long river of time and space.

Therefore, if you want to carry out 'time conversion', the only power that can be borrowed is the power from the future and from a higher dimension than the past.

"...Albert creatively solved the plasticity of time in "A New Measurement of the Length of Time", understanding it with the perception of a low-level wizard. The plasticity of time is manifested in that it can be bent."

Master Baoyangzi stretched out his pointer and drew a long, thin line in the void: "You can assume that this long line is the materialized timeline... This line bends and then bends under the action of external forces... ...When its curvature reaches a certain level, you will find that it forms a closed loop... Because time has the characteristic of 'one-way movement', this line will still follow the original direction after the closed loop appears. keep going……"

Zheng Qing stared at the straight line in the void with a knot in the middle, slightly lost in thought.

If you guessed correctly, that 'knot' is the reset timeline. It is independent of the normal timeline, but attached to it.

The pointer in Master Baoyangzi's hand was pointed at the intersection of the 'time knot' and the 'timeline', and he emphasized slightly: "This point is the 'paradox point' mentioned by Master Bachzaweil - in time During the reset trip, if the traveler goes back in time and kills his grandparents before his father was born, then the 'paradox point' will take effect and break the connection between the 'knot' and the 'timeline' .

This will cause the 'time knot' to break away from the timeline and float alone outside the timeline. In more popular terms, this 'time knot' and the 'people in the knot' have been exiled out of time and space and trapped in the turbulence of time and space.

Of course, the 'grandparents paradox' is the simplest and easiest to understand of all 'paradoxes'. The reason why I mention this concept is to warn you not to try to make any changes after entering the reset timeline. Because any change may cause the separation of the 'time knot' and the 'timeline'... and then cause you to be completely lost in the turbulence of time and space.

I don’t need to explain the horror of getting lost in the turbulence of time and space. You just need to know that even the legendary wizard would have a hard time finding you among the noisy signals if he didn’t keep an eye on you when the ‘paradox point’ was in effect. trace. "

Zheng Qing subconsciously raised his head and glanced at Lao Yao sitting behind the desk.

The reason why I chose to take such a very dangerous course in Lao Yao's office today is because Lao Yao is a genuine legendary wizard.

At this moment, noticing the slightly grateful gaze of the young wizard, the dean of Jiuyou Academy blew out a smoke ring with a satisfied expression on his face.

"These are the basic concepts. Let's make some simple inferences based on these concepts."

Baoyangzi put away his pointer and looked at the two young wizards in front of him with burning eyes. His voice suddenly became high-pitched and distant: "Bending time requires powerful magic. Where does the magic come from?

Starting from the asymmetry of the ‘time dimension’.

Normally, magic flows from higher dimensions to lower dimensions. But the direction of the timeline is retrograde from low dimensions to high dimensions. This means that we only need to use magic to leverage this significant asymmetry in the 'time dimension', and we can bend the timeline with the help of powerful magic from the higher dimensions of the future.

The greater the curvature, the more powerful the magic required.

Powerful magic will cause time to accelerate greatly.

Therefore, when a 'time knot' is formed, an extremely powerful magic power surges around it. This magic power is both a barrier and a restraint.

This barrier protects the Time Knot.

This magic power can accelerate the flow of time within the time knot.

You think you've traveled back in time and arrived at 'normal' time, but that's an illusion. In fact, you experienced everything about the 'reset' at a very fast time flow rate.

Reflected in reality, when you go back to the past and slowly come to the 'now' along the timeline, the original 'now' has only passed for a moment, or a shorter time.

You may disappear in front of your companion one second, and appear behind him the next. In this second, you have experienced days, months, or even years more than your companion.

Under the premise that the flow of time is accelerating, as long as you do not make any changes to the closed timeline, the 'paradox point' will not be harmed and the Bachzawiel space-time storm can be safely avoided.

In short, use magic to leverage the asymmetry in the 'time dimension' to bend the timeline; because of the single direction, time will return from the future to the past as the curvature changes - this is the basic principle of time conversion. principle. "
