For someone in the Jianghu, fostering a satisfactory disciple is an immensely energy-consuming task.
Not to mention the costs of various soups, water, and dietary supplements for cultivation.
When Lu Yuan practiced martial arts, he spent ten silver tales a month. A year's practice amounted to one hundred twenty silver tales.
Average people need about four years to unblock one meridian, which approximates to five hundred silver tales.
As for a large martial arts faction, the minimum achievement for a disciple to be considered valuable would be a third-rate prowess.
By this standard, cultivating a third-rate disciple requires eight years and a thousand silver tales.
This is just the basic expenditure. If you include other costs like teaching efforts and faction-specific resources, the expenses would increase even more.
