It's just that. The thread basically explained which levels of Immortal Worlds act as layers of silver sea, and that it has been accepted (how silver sea's layers were treated at that time is what immortal worlds are like, except that SS layers are 5-D and this is 4-D/6-D). Some abilities are basically Law Manipulation, Power Nullification, Death manipulation, just take that if you want to chop. Also in the blog and thread it is also said that size and the above are inversely proportional to each other, to the extent that a character can easily create infinite Tier 2 structures that are turned into a normal person when the size is reduced to ten times, Yang Qi does the above but instead of just ten times, it is to the extent that the whole infinite structure is made finite and as said in the thread/blog he is now fodder with the characters can treat immortal worlds (3000th rank) like a cell, apply that to his 6-D key too because God Realm (infinitely immortal worlds with rank 3000 but a 6-D version, as AP said). I think that's self-explanatory for how Yang Qi's layers work (beside Destiny Valuation), not everything has to be as obvious as possible. If you still do not accept, you can say it's baseline or ask
@Muchacho_mrm for trillions layers
