When Xiao Chen learned of Old Skeleton's identity, he was utterly astounded and hurriedly paid his respects. He held this legendary figure in high esteem.
"The Supreme Human Realm is extremely difficult to break through, just as its name implies, it represents the ultimate limit that a living being can reach. Because if one breaks through this barrier, they will have transcended humanity, and from then on, the seas will be theirs to swim and the skies theirs to soar. The shackles like an insurmountable gulf cannot be broken through merely by cultivation and enlightenment; various opportunities and fortunes are needed."
This is how the Seven-Color Skeleton King guided him.
Countless outstanding figures throughout the ages have practiced in this realm for thousands of years, with barely any progress. Each level was an insurmountable gulf; Xiao Chen understood this deeply.
