Moonlight Forest.

With his sword at the ready, Raymond quietly but confidently travelled through the dense shrubbery of the Moonlight Forest. As he walked, Raymond noticed that the spiritual energy in the air seemed to be thicker the deeper he walked into the forest. Raymond knew that the density of spiritual energy depended on plenty of factors, and one of the most important ones was spiritual veins.

A spiritual vein could decide the fate of a sect and was one of the reasons that sects were able to prosper. If you cultivated day and night in a place with twice as thick spiritual energy, your cultivation speed would naturally be a lot faster. Pair that with more powerful cultivation techniques and abundant cultivation resources and masters to teach you, and you would naturally travel way further on the path of cultivation compared to a rogue cultivator.
