"...The second theorem of Magic Theory states that magic power cannot spontaneously transfer from a lower-dimensional individual to a higher-dimensional individual—note that this is a 'one-way movement,' meaning that under normal circumstances, magic power flows from higher dimensions to lower dimensions. Similarly, time's flow from the 'past' toward the 'future' also possesses an inherent characteristic of 'one-way movement.'"
"...Pay attention to this word—'one-way.' It means that in the dimension of time, one side has 'direction' while the other has 'no direction'; it is 'asymmetrical.' It also means that even if you go from the past to the present, then return to the past, and then come to the present again, the entire process remains 'one-way.' There is no 'break' or 'parallel' in the Timeline. Nor do the Parallel Worlds you imagine exist."
"...The past is certain. Certainty is a convergent state: orderly, controllable, and observable. The future is uncertain. Uncertainty is a divergent state: disorderly, chaotic, and unobservable... This process of moving from order toward disorder is one of the most fundamental concepts in this world."
"...Perhaps someone will ask: if the future is unobservable, then what are the futures predicted by Divination Studies? Here, I must emphasize one point. The so-called unobservability of the future means that the future holds infinite possibilities, and we cannot observe every single one of them. The future observed through divination is the most likely among all possibilities, but it is not an absolute outcome. When it comes to the future, anything is possible."
Having explained this much, Bao Yangzi paused, giving the two young wizards time to take notes. The three large lines of writing hanging in midair had already been densely annotated with explanatory terms.
The old man glanced once more at his "blackboard," stroked his beard with satisfaction, then lowered his
