Seeing Ciri's somewhat puzzled expression, Tereddy then explained, "The old guy has indeed done a lot for the Vatira plane, so much so that the will of the Vatira plane has always helped him suppress my existence. That's why you'll see him here, and it's rare for old guys to show up outside. ”

"You should know that time is divided into ordinary time and ultimate time. Ordinary time mages use and study the ordinary time of each plane, and ordinary time is actually controlled and influenced by the will of each plane. ”

"And what the old guy has been studying is the ultimate time, the highest time in the magical world beyond all planes. It was the accident of the experiment involving the ultimate time that made me appear. Although the Vatira plane has always helped the old guy suppress me, another force that is much stronger than the will of the plane has been following a certain law to stabilize me and eliminate him. That kind of power can't be stopped even by the will of the Vatira plane, and it is foreseeable that the old guy will disappear completely soon, which is why he is so eager to find the inheritor. ”

"The sooner I appear, the sooner the will suppression of the Vatira plane will be eliminated, and now the old guy may disappear at any time. ”

Tredy's words made Ciri's heart feel heavier and heavier, and it seemed that Mr. DeWitt's own situation had reached an irreparable and extremely bad situation. As a client, Devit is not so sad, and he is ready for the final ending.

Since there is not much time left, Ciri once again stepped up his study pace, sometimes even for days without rest, and only when he was really tired, he would interrupt his studies and relax.

Tredy stayed with the two of them since he appeared, as he and Mr. DeWitt did have to stay at a distance for some unknown reason and couldn't leave at will. However, Tredy will not listen to any of DeWitt's explanations because he does not want to follow DeWitt's path again. When Devit and Ciri begin to teach, Tredy will set up a soundproof circle and a pre-prepared magic book next to him.

Because Ciri deliberately accelerated, he quickly learned the basics of time science that Devit knew. Ciri undoubtedly passed DeWitt's evaluation review perfectly, so DeWitt began to pass on all the research he had done over the years.

With time pressed and no one knew when DeWitt would disappear, he went straight to the story of his life's biggest discovery--- ultimate time.

The concept of ultimate time was already in existence when the concept of ordinary time appeared. The time mage found that there are actually some differences in time in each plane, and even the speed of time flow in each plane and each layer of space is not the same, so is there a final authority that overrides all the different times?

The answer is yes, because the mage found that in the outer worlds outside the plane and the final city, where the planes meet, time follows a uniform schedule that is different from that in other planes. In addition, powerful time-based spells in the plane will permanently affect the movement of time in an area, and in places like the Out-of-Bounds and the City of the End, even the most powerful time-based spells at the time will have no effect on their own time movement after the spell has passed.

Therefore, chronology divides time into two categories: ordinary time and ultimate time. Ultimate time is the highest standard time in the wizarding world, and the rest of the time is normal time.

Devitt found through research that in the ultimate time, the present state is a certain point, and the future and the past are actually uncertain. It's easy to understand that the future is uncertain, so why is the past uncertain as well?

For example, all of your relationships with yourself have not changed. In a very distant place, a magical plant has changed in the past, and it leads to you in the present state just as much as the unchanged past of the magical plant. If your future is connected to this magical plant, a different past will lead to a completely different future.

In ultimate time, you are like the connecting point in the middle of the hourglass, and the past and the future are the two ends of the hourglass, and countless pasts connect the present point, and then diverge into countless futures.

DeWitt had an accident at the time, causing his "now" state to be moved forward to the position of Vatila without doing anything to help him, which is the state that Drydy was in. The original Devit has been judged to be "future" in Ultimate Time.

Therefore, it should be that Ultimate Time has been trying to fix the error, keeping the Tredy in the "now" state and eliminating the DeWitt in the "future" state. Once DeWitt disappears, he will never reappear, because with what Tredy wants and does, there is already a serious conflict with DeWitt, so Tredy will never have the future of DeWitt.

What Devitt wants to impart to Ciri is some of his conclusions about the laws of the summary of ultimate time over the years, and his method of exploring ultimate time.

To explore the ultimate time, it is very complicated to study and understand the ultimate time. There are many basic concepts involved, including "I", "being", "truth", and so on (Note 1). The more basic things are, the more complex they are, because you can't prove them, you can't explain them.

With the help of DeWitt, with Ciri's own chronology and intellectual talents, it took a long time to initially establish the concept of "true self existence" in his heart. Of course, Ciri only has some preliminary conceptual understanding, because the understanding of these basic concepts is never-ending.

With the gradual deepening of the cognition of the "existence of the true self", supplemented by some of De Witt's other temporal theory knowledge and the rune circle of specific time, he will slowly vaguely feel the countless past self. In fact, DeWitt's research on ultimate time only lasts here, and when he wants to work out something else based on these theories, the experiment goes awry, and Drydy is summoned and takes his place as the "now", while DeWitt himself becomes the wrong "future".

DeWitt's research is easy to say but extremely complex to do, requiring not only the learner's extremely high temporal and intellectual talents, but also a variety of temporal circles, and these incomparably complex temporal circles alone took Ciri a long time to learn.

Later, all kinds of basic cognitions bothered him for a long time, and by the time Ciri had basically accepted all of DeWitt's research results, two years had passed unconsciously. Several times during this period, Ciri wanted to give up, away from the complex theoretical knowledge that gives headaches when he sees it. But seeing that Teacher DeWitt was getting worse and worse, Ciri couldn't open his mouth and give up.

During the two years of teaching Ciri, DeWitt's condition deteriorated significantly. In the past few years, Drydy has been trying his best to collect some natural treasures that are helpful to DeWitt. Although the two used to quarrel and have different concepts, and even a kind of opposition between you and self, Drydy and DeWitt's same nature allowed him to try his best to help this amazingly talented but miserable other self in his life.
