Fang Ao had a secret art in his possession called the Eye of Providence.
It was a mystery-type technique that allowed a user to observe the fortuitous opportunities a person might have in the immediate future. This secret art was exclusive to the Augur Clan, one of the most reclusive organizations in the myriad cultivation realms.
The Augur Clan only had a single inheritor for each generation, but nobody dared to try to mess with them or extort them. This was because, apart from the Eye of Providence, they also had another secret art that was just as unique; the Compound Summons Art. This art allowed them to summon the spirits of the past inheritors and temporarily borrow their strength.
With this combination, it was not surprising that every inheritor in each generation grew extremely powerful in no time, easily snagging many fortuitous encounters wherever they went. Every inheritor of the Augur Clan grew up to be strong powerhouses.
