Regarding the chaotic situation of the current era of great contention, Su Xin had a long discussion with Lord Ksitigarbha and also recounted some events that had taken place after Lord Ksitigarbha's departure, to facilitate his understanding of the current situation in Jianghu.
After finishing his account, Lord Ksitigarbha handed Su Xin an object—it turned out to be a fragment of something. It didn't look like a bone nor a scale, yet it bore an incredibly strong aura, the power within it extraordinarily astonishing.
Lord Ksitigarbha said, "Legend has it that this object is a part that broke off from the Demon Emperor during the great battle with the Human Ancestor. Whether it is a scale or a bone is unknown. Although it is just a small piece, the power it contains is truly astounding. Yama Heavenly Son and I have already refined a part of it. This is what is left for you."
