Thus, to ensure the strength of the high ranks within the sect, a sect can often only select one disciple for focused training.
Once this disciple reached the level of a Human Immortal, the sect would have a high-level power in place, and once this objective was achieved, they would withdraw resources and let the Immortal find their own opportunities.
The sect would then turn its attention to selecting another Immortal candidate and start training the second Immortal to ensure a continuous line of Immortals within the sect, flourishing indefinitely.
There was a benefit to this approach.
Generally, a Human Immortal only has a lifespan of three thousand years.
By the time they become Immortals, most are already seven to eight hundred years old, and the time they have left to live is merely two to two thousand three hundred years.
Thus, taking into account a training cycle of eight hundred years for fostering a Human Immortal.
