If the Primordial Sovereign had obtained the current Kongtong Seal, there wouldn't have been much he could do either. At most, he could have combined it with half of Mount Buzhou to refine a Postnatal treasure, after all... he didn't have the Chaos Cauldron at hand, unable to reflect Mount Buzhou into an Innate state, leaving it as a Postnatal object.
If he didn't enhance it, the Kongtong Seal wouldn't be very useful, barely sufficient to contend with diamond-tier masters, let alone those above the diamond tier, only able to exert the undying power of its imprint.
