Though there was no sound, Bai Ye could "hear" spacetime trembling, as if he had passed through layer after layer of chilly mist.
His sense of time vanished completely. He had no idea whether he had traveled through the mist for a second or a century, until the Pangu USB Drive sent him a notification.

He had plenty of firsthand experience with that. An Xiaotong's death had been exactly like that—countless tiny decisions and actions had ultimately led to it happening.
The same applied to this trip a hundred years into the past. For example, if he casually killed an inconspicuous passerby, that person might indeed have been insignificant, but their descendant could have participated in some major event, become a certain leader's guard, and taken a bullet for that leader at a crucial moment.
