No, where I find myself in disagreement is their theories on the middle dantian and shen energy. As I have heard it, the leading position is that Shen is an energy wholly derived from potent cultivators and spirit beasts, through which their will is imprinted upon the world, which is composed of lesser energy, qi. This is why those conflict between those of the fourth realm and above so easily alter or scar their surroundings, Shen is a semi divine energy, existing above the base mortal world, the first step toward wielding the power of the great spirits. This is why it allows us to escape the shackles of the world and fly, or alter the workings of the systems around is in ways beyond the brute force of the third realm.
This is wrong. Shen exists in the world around us, not merely as a side effect of potent spirits, but as another fundamental aspect of the material world. All forms of material and energy are qi, when broken down to their fundamental state, but my time under Guru Abhinavagupta, a man of great renown in the west, I have come to understand this. Men, beasts and spirits change the world by exerting their will, their shen upon it, this is true, but the world changes itself. We are not not as separate from material cycles as many would like to think. Shen is the energy of laws and reactions. When you strike flint to make fire, this is a miniscule application of shen. The patterns of winds which derive the weather is an application of shen. Not the winds and rains themselves of course, but the fundamental logic which drives them.
This is the source of it's potency and power when used in mortal hands. It overrides qi because qi operates as it does thanks to the laws and reactions imposed upon it by Shen. Now you may argue, is what I just described not the provenance of the third dantian? Sovereignty, Law, Truth; whatever you wish to call it?
I would answer that it is, and that imagining those things to be a third source of energy rather than a refinement of Shen is the greatest failing of Imperial Qi Theory. Of course, the truth is that it is really just a difference of power at that point. If it is said that a fourth realm wields Law as a mortal would a sharp rock, then it may be said that an Eight Realm wields it as a shaped cudgel. It is only ascension that allows true mastery. It is only our pride and insistence on supremacy which deludes us otherwise.
