Another piece of information, it's not really about the update, it's more about the lore.
This is what Nicky said about talent: "There is a lot of factors that determine talent.
1) cultivation talent (ability to absorb qi, speed, how much before getting tired, how much is lost)
2) comprehension talent (this is about understanding Dao)
3) bodily talent (both for growth and for alchemy)
4) soul talent (there is a lot that goes into this, but main one is willpower)
Then you add various mutations, physiques, aptitudes (for various Dao) and so on.
They are also valued differently in different places. Lower tier world usually place 1,3 above everything else (since there is no possibility to change it). CR tends to value 2,4 much higher"
About the MC: "1 is top tier, 2 is beyond top tier, 3 is very, very good, 4 remains to be seen"
