"I've finally come to a complete understanding,"
Lin Xian lifted his head and looked at Liu Feng:
"So you're saying, as long as there's an event that can influence the original trajectory of the future, causing a butterfly effect in the future's space-time, the value on this 'Space-Time Clock' will change, and this changing value is what's known as space-time curvature, or what everyone commonly refers to as world-line curvature."
Liu Feng nodded and gave Lin Xian a thumbs up:
"You're really smart."
"Then why does the number on this remain at 0.0000000?" Lin Xian pressed on.
"That indicates that the space-time curvature has not changed yet, it's as simple as that," Liu Feng said, spreading his hands.
"That's not right, how could the space-time curvature not change?"
Lin Xian pondered, propping up his chin:
"When exactly was this Space-Time Clock created?"
"It was made last month."
"Be more specific with the time, was it before May 20th?"
