The idea that one could go through the body tempering of the fourth rank of mortal cultivation was flawed, which we accidentally discovered and proved when we went through this process for the second time.
With that, I just couldn't help but wonder—if one could temper their body more than once, for what reason would I believe they couldn't do it more than just once per cultivation cycle?
Sure, it was an awful experience to go through, one that I literally wouldn't wish upon my greatest enemy...
And yet, if there was even the slightest chance we could go through it again, I was willing to do it.
Not because I was into feeling pain. It was simply because going through this process yet again could, quite possibly, raise our potential in the future.
