For a hundred years, no one had been able to comprehend Floating Light Shadow because it required a high level of comprehension! No one in the world, apart from the 10 Holy Talents who had extremely high levels of comprehension, were able to comprehend Floating Light Shadow.
The First Prince wanted to borrow the abilities of the 10 Holy Talents to help him comprehend the technique so that he could cultivate it, since it had been lost for years. However, every batch of the top 10 Holy Talents were invited to the Sanctuary, causing all of them to be beyond the First Prince's reach.
Bai Qixiong was the only exception. As the Holy Meet participant who had attained the 11th position, he was the only person, apart from the top 10 Holy Talents, who had the highest possibility of comprehending the saint level cultivation technique, and he was able to do so.
