Xu Yang didn't waste words, paid a spirit stone, and received a wooden token before entering the island.
Cultivators, seizing the essence of heaven and earth, encroaching on the mysteries of the sun and moon, rely on spiritual energy to practice.
Spiritual energy is sustenance, it is strength, it is hope and the future.
Therefore, cultivators seldom stay in the mortal world for long, because there is no spiritual energy there, which is of no help to cultivation; staying too long can even cause their cultivation to regress, just like people suffering from malnutrition without food.
Such an important resource naturally needed to be controlled. Those places abundant in spiritual energy had long been occupied by major forces. Loose cultivators wanting to enter must pay spirit stones, or else they would be driven away or even killed on the spot.
