"What did you say?!"
While the name was different, there was no mistaking it. There could be no other basic force of this universe stopping normal cultivators from advancing further than entropy!
By looking at how I obtained the power to wrong ith it in the first place, everything would make sense. Basically, unless one could use a system like I did to save himself from the decay, then overloading oneself with magic force would inevitably result in the entropy poisoning.
And looking at the way in which it worked, it would be no wonder why it was called a power of decay!
