"Six degrees of separation" is a common phrase, heck they even made a movie out of it with Will Smith in it.
Based on the work on Milgram, this phrase taken to its extreme implies that every person in this world is connected to another person through no more than six separate other friends/families/acquintance.
This is truly a very astounding fact that is true as well in the way the neurons in the brain wired together, or how the internet linked with each other etc.
I'm sure most of you all have heard of the Oracle of Kevin Bacon, where ppl attempt to link all actors in Hollywood with Kevin Bacon?
Well in this game of six degree of separation in Wuxia, take GJ in JY, i challenge you all to find a character in JY that takes more than six steps to link to GJ.
Good Luck,
Han Solo
