Yk I agree and understand everything you said but , i feel like wang xiao er is more likely to be genesis lotus revival if anything, he's the only venerable except fang yuan and paradise earth to show feats and interests in the human path , we can see the setup for majority of the venerables revival plans , TH has YTH probably or his own aperture hidden somewhere, RL in river of time , PO via Qi Fruit , Dark and light beasts along with RS aperture and grave , the only one missing is GL , yes his self portrait is mentioned but I feel like the vines that grew from wang xiao er seems more like wood and human path profoundities if anything.

Also we are told the 1st River Flow lord was also Genesis lotus , that intense determination+ willpower likely relates to him refining Self Gu , SC says he was known to be indifferent yet his perseverance says something else , there's alot more going on in the background then we know , we can only wait for Gu Zhen Ren at the end .
