Lastly, there is the nether path, the most mysterious one among these three. The reason for this is simple, it has no fixed path. The closed to a fixed path could be the 'Domain', and that is only because spirits have a high affinity for domains, and they are the citizen of the nether world.
Yet, at the same time, anyone who isn't a spirit can still cultivate the nether path, but they don't necessarily need to choose the domain path. Throughout the ages, the nether path has been called to be the most difficult one to achieve great success in, if one wasn't a spirit. But, it is also said that each and everyone that succeed was an extremely strong figure.
Then again, the home of any nether path cultivator is the netherworld. Unlike the physical world that is divided into different sections with small, medium, large and upper world, the netherworld is one huge world that combines the whole space of the physical world together.
