In the Starry Universe, the quickest method to travel from one place to another is, of course, teleportation.
However, even teleportation requires two location points. Otherwise, no matter how short the distance, one can only rely on oneself.
Although Li Chen's speed doesn't claim dominance over the universe, it is certainly exceptional. Yet, searching for someone who left decades ago by tracing faint causality marks left behind is not an easy task.
It has nothing to do with speed. After traveling a certain distance, Li Chen has to stop and carefully search for traces again to confirm that he hasn't deviated from his path.
After all, the Starry Universe is so vast that even a slight deviation from the intended route could lead to being completely off track.
It's like a person in the desert walking along a straight line with blindfolds, initially just a little off, but as the deviation grows, the direction soon becomes entirely skewed.
