In fact, the grade of pills, the grade of weapons, and so on, in the Lower-Class Star Region, are all corresponding to the cultivators' cultivation realm.
This is not only true in the Lower-Class Star Region, but also in the Middle-Class Star Region, High-Grade Star Domain, and finally the Holy Domain.
A First Grade Pill is not useless for cultivators above the Spirit Transformation Realm, but its effect is greatly reduced.
Therefore, usually, only cultivators in the Spirit Transformation Realm would purchase a First Grade Pill.
Of course, if it reaches the level of Top-Grade, then even cultivators in the Spirit Body Realm would buy it.
Why?
Because this is a First Grade Pill!
A Top-Grade level First Grade Pill's effect compares to a Low-Grade Second Grade Pill, and the price is much lower, so why not choose this?
Anyone who's not a fool would choose this.
