"Empty inside? What does that mean?" After hearing the Little Sprite's description, Mo Ling asked in confusion.
"It means... there's nothing there. I can see human wishes and use them to glimpse your possible futures. It's like inferring the flow of the River of Time from its riverbed. It's a simple calculation that requires some known conditions. But there are no known conditions on you, so I can't calculate anything."

Yet even after hearing all that, Mo Ling was still completely lost.

"He's a very good friend of mine. He helped me a lot. In another Time Fragment—maybe the past, maybe the future—I copied my current appearance from him."
As it spoke, the Little Sprite pointed at its own cube head.
Router could no longer hold back after listening to the Little Sprite's rather muddled explanation. After thinking for a moment, he asked it a question.
"Why don't your descriptions of time distinguish between before and after?"
"Because time itself has no before or after. Time is made up of overlapping fragments. The past and future occur at the same moment and flow in parallel. Humanity's perception of time gave humans the concept of sequence, but in truth, there is no first or last."
"No first or last? But you met that other guy before you met him. Isn't that a temporal sequence?" Router asked, pointing at Mo Ling beside him.
"No." The Little Sprite shook its head. "That is merely a sequence using 'myself' as the reference frame. Time itself has no sequence, just like space."
"When humans describe space, they need to establish a reference frame—using the observer as the reference frame, or fixed coordinates as the
