Legend of the Paladin
So whats the connection between Slow-Witted Song and Senior White? Song left behind the technique, while White has a full set as his soulbound artifact. Did Slow Witted Song save Heavenly Way White? Song has experience with time travel, so maybe a time travel thing? His whole Army could be to help White
My current pet theory is that Shuhang is somehow related to the first Wielder of Will. He seems to have a natural affinity, either good or bad, with every Wielder of Will and Ruler of the Netherworld. He also has all the luck. Senior White only has good luck but Shuhang has extremely good AND bad luck. Not to mention that absolutely insane cultivation rate. Shuhang is either connected to the deepest levels of existence or he is the most OP creation of Fate and Chance to ever exist.
