In fact, after Han Fei learned the Golden Light Movement Technique, he felt that even if he left the Medicine King World now, Bei Luochen might not be able to stop him.
After asking Old Yuan, Han Fei knew that whether it was the Sea Establishment Realm or the Sky Opening Realm, in terms of speed, there would be a balance in the end.
As for the fundamental reason for the difference in speed, it was essentially a problem of how to control space and time. The Sky Opening realm was obviously stronger in this aspect. However, this problem had almost become a problem that the Sea Establishment realm and Sky Opening realm powerhouses had been pursuing.
However, Han Fei didn't want to leave yet.
Since he was already in the Medicine King World… and the Medicine King World was one the main enemies of the Yin-Yang World, there was nothing wrong for him to take revenge.
