…but of course, we must first talk about the downsides of such techniques.
The Sumeru Mountain Law required a minimum Earth-Grade Earth Element Spirit Root to be able to get started in it. This was a steep barrier that blocked many aspiring cultivators who had suffered to gather this much sect merits, leaving them feeling despair as they could only pick something with lighter requirements.
The Void Limitless Sutra's limitation was already stated, needing either a void/space element spirit root or a void-related physique. This was redundant for Li Ling as the Tai Xu Mysterious Method could give him the versatility of the void element apart from ascension in realm.
The Soul Splitting Divine Art had too many limitations to count. Firstly, one had to have a strong soul to be able to split many copies, or you might only end up splitting one clone, which was basically useless for the kind of 'hack' effect this cultivation technique brought when you re-fused the separate souls.
