Kong Xiang—the original body—could make out a karmic thread that connected him to Master Lin. But that wasn't the shocking thing; it was the fact that the thread superimposed with two other karmic threads he already had.
The first was from an object of the Reincarnation Taboo Universe, the Golden Orb, to be exact. Although its function was eventually modified to serve as an extra guarantee during his Samsaric cycles, its original formation was due to the actions of a specific person whose action led to the destruction of the entire Myriad Path World.
The second line was from someone who was closely linked to the causal effect and had monitored Kong Xiang's condition during his Samsaric cycles, eventually solidifying their relationship after he broke the Reincarnation Taboo Spell.
Master Fei.
