Dao Qiongcang, Bei Huai.
The reason Dao Qiongcang is still merely who he is today is that he walked a path different from Bei Huai's.
He could not remain loyal to the Qianshi Dao Clan, yet retained his human nature, so he chose to build something out of nothing.
This is what Ai Cangsheng currently believes.
To this day, he still cannot see through Dao Qiongcang, aware that all the insights he could have about "Dao Qiongcang" are only what Dao Qiongcang wants him to see.
As for Bei Huai...
Completely different!
In stark contrast to the secretive Dao Qiongcang, Bei Huai is forever transparent, forever brazen.
He remained loyal to the Mournful Emperor Realm, as well as to himself, in a mindset completely alien to the average person.
Step by step, he followed the blueprint laid out by the Mournful Emperor Realm—leveraging the resources of the Holy Emperor Family, realizing his innate talents, passing the family's truth-seeking trials, until reaching that final step.
