I can't imagine with the limitless potential dao marks that many pseudos have at their disposal , eg .Variant human lords lived long and presumably accumulated dao marks long after their 3rd myriad, but their 3rd myriad didn't make them venerable .Their dao marks are still there , Qi Jue and Qi Sea with their ability to absorb fruits for dao marks potentially as much as they'd want , and all sorts of other methods pseudos would have to accumulate dao marks . The difference of dao marks for venerables compared to pseudos can't really be the defining difference ,since 10 of these variant human lords who each shouldn't face extreme dao mark difference w Primordial origin got solo'd one v 10 and lost definitively (albeit surviving) . I feel its more likely that each venerable who are supreme grandmasters in their own path need to achieve their own specialty that places them far beyond , Limitless with his endless dao marks , reckless savage who has the greatest strength of all history after absorbing countless immemorial beasts , Paradise Earth who was somehow able to create paradises without tribulations (is this a Heaven path profundity? ), Spectral soul with his non conflicting dao marks from orderly well ,and a transcendent soul of hundred million man that is the strongest legendary immemorial in itself , Their dao marks and rank 9 essence are hardly what ever sets them apart except for limitless demon venerable .It's that even without being venerables ,these inviduals are already unmatched . Although .. .lots of them do lose to Dao Guardians before rank 9 .Reckless lost twice I believe ? Well ,dao guardians are also impressive .Creation of an entire race and suppressing two demon venerables , destiny Song who shows the deepest understanding of a yet to exist path , revival millions of years in the future through a method that has yet to exist .. Now that fate has been destroyed , It would be great to see venerable ascension of a dao guardian albeit it's fy who's certain to ascend first in this era as the Mc .
This reminds me, did Fang Yuan use Regret Gu for anything critical at all after he received it from Red Lotus's Strone Island? Red Lotus was a Time Path Venerable, able to see the future accurately. He left his arrangements exquisitely for Fang Yuan to achieve his goals: his true meaning, immortal materials, Future Self, etc. It then follows that the Regret Gu and 3000 Heaven Path Dao Marks are on purpose as well. Red Lotus must have left Regret Gu for Fang Yuan to use to construct this Gu House along with the Heaven Path Dao Marks to make this Gu House possible to begin with on purpose. I also find it strange the quantity of Heaven Path Dao Marks was not so little that it would not help Fang Yuan, nor was it so much it would cripple him, allowing the various forces to kill him. Nothing done by the Venerables coincidentally. I am convinced Red Lotus still has future plans for Fang Yuan.
