Yes, Heavenly Dao was also a cultivator!
Later he dare to take the risk and bet his future as well as his own hard worked cultivation.
In the Celestial Realm, if one want to breakthrough and enter in this realm or, advance in this realm.
They only need huge amount of qi and alternatively if possible then faith of races.
No matter what race, it could human, dragon angel and even demons.
No one wanted to risk ones future on a race and most of cultivators always stuck on this cultivation realm, accumulating qi to breakthrough in next stage.
Of course the qi and what they gather isn't same.
In the ancient times when this process was going on, a genius who dare to risk his future appeared.
He took an oath on his own name, because at that time there was no heavenly dao present, that person took an oath that he will take all heaven and earth as his own race.
Those who will believe on him and those who won't, he will never be partial.
He will be the 'rule' who will always be fair.
