First, one must open a Grotto Heaven within their body to become a Celestial Venerable.
Second, one must gain the recognition of the Celestial Observation Cauldron.
As for how to gain the Celestial Observation Cauldron's recognition, no one throughout history has ever known.
However, right now, Wang Xiao felt he had seemingly figured out the trick!
'To gain the Celestial Observation Cauldron's recognition, it's almost certain that I must comprehend the Nine Origin Great Dao. Then, after unifying the Nine Origin Great Dao, I must open a Grotto Heaven in my body!'
The difficulty of this was truly immense!
First, one's Inner World and Great Daoist Nascent Soul needed to be sufficiently refined; otherwise, they couldn't bear the power of the Nine Origin Dao Fruits.
Second, it required an immense amount of time to comprehend the Origin Great Dao, which demanded extremely high comprehension and fortuitous encounters.
