Yu Beibei was entangled with Chu Pingfan and You'er. Thanks to that, they had formed a feud with Ling Baiyun.
The conflict between Ling Baiyun and Chu Pingfan was inevitable anyway.
Chu Xuan was trying to see if he could change the fate of a region.
Based on his understanding of the Dao of Fate, Chu Pingfan had the chance to replace Ling Baiyun and become the son of fate of the Eastern Region.
The son of fate would have a natural advantage in the region due to his great luck. He would not die in a crisis, but would become stronger after each crisis. His enemies would also be suppressed by fate.
Chu Pingfan cultivated the Extreme Dao.
The Extreme Dao was very special. It carried the great fate of the Extreme Dao, so he was naturally not affected by the advantages Ling Baiyun had as the son of fate of the Eastern Region.
