'The road of Soul cultivation supreme energy:
The soul cultivation energy is like the other supreme energies away from the tech energy, it suffers from the environment here. The environment here is based on tech energy mainly with few amounts of other energies.
So, when you try to learn and control the soul cultivation energy, you should use the special items that transform the tech energy in the environment into high dense spiritual energy.
These items aren't known to the public, so you can't find it easily. I gathered a small list of some items including special herbs and ores that will help you transform the energy into spiritual energy.
I heard from Moran kid that you seek to learn the five supreme energies. The situation of soul cultivation energy is basically the same at other energies and the solution is also the same.
