"Under different theoretical frameworks, time takes different forms."
Mr. Wu did not immediately answer the tabby cat's reproach. Instead, he first explained the latter question at an exceedingly slow pace:
"I do not deny that, in other theories, time may take other shapes: spots, ripples, even simple vectors, or a porous sponge—like a blind man's side-view sketch of an elephant, what one sees from different angles will always differ in one way or another—but in Dimensional Theory, the Time Dimension Line and Time is an Angle do not conflict."
"Who says a dimension line must be a line?"
"The Spatial Dimension Line is full of tension, the Weight Dimension Line is compressed into an arc, and the Sound Dimension Line trembles. The dimension lines corresponding to every different concept possess their own characteristics. Time is the same. Its dimension line is concave, forming an angle."
"As for why I did not warn you."
"Do you remember our earlier analysis? For wizards, time and destiny are a 'line-thread' strung together from the different choices made at every moment. In my present state, if I interfered with your choice, it would be difficult to imagine what changes might follow... That would not necessarily be a good thing for you. I could only try to stand outside the 'angles' of those strands and gently pluck the fine strings upon those angles, using that to remind you."
"Then why can you speak about it now?" The Yellow Flower Cat grew more confused the more it listened.
"Because you have already made your choice, and I wish to reinforce this Time Thread that you have seen... By speaking with you, I have fixed this line. Even if that little Xiangliu achieves the status of an Ancient One, he cannot alter facts that have already occurred...
