"What a joke, is Blue Moon Island so easy to enter? Even if Pan Shan possesses strength of thirty two oxen, he might still not prevail over Hall Master."
The people of the town were all aware about the condition for entering Blue Moon Island, which was to defeat the local hall master.
What sort of people were hall masters? They were higher level flux experts who were just a step away from entering the realm of Flux Master Experts.
Thus, although on Flux Expert Day every subservient island's hall master could recommend three people to Blue Moon Island, these spots weren't usually filled. This was because prevailing over hall masters was simply too difficult.
The reward worth focusing on was actually the qualifications to enter the outer sect. In other words, to take a step back and become an outer disciple of Blue Moon Island by defeating three disciples of Hall Master.
