Each type of cultivation technique would differ according to the type, and the number of basic cultivation techniques would also be different.
Take the Overpowering Saber as an example. Some of those basic techniques are based on cultivating the external skills of saber fighting, some are based on cultivating saber intent, and some are based on cultivating the internal strength of saber techniques.
That was also why the cultivation techniques in that world could be directly used to accumulate and increase one's cultivation.
That was because the cultivation technique itself had already encompassed inner strength.
Similarly, it was the same for the basic cultivation techniques of the body-refining system.
