In general, in the beginning of this story most of the Item ranks/grades, etc. They receive similar names as they are based on the realms of cultivation.
Alchemy (Alchemists and Pills) are divided into 9 Grades, almost corresponding to each Cultivation Realm:
1: Grade Spiritual Common.

3: Grade Spiritual Heaven.
4: Grade Spiritual Spirit.
5: Grade Spiritual Noble.
6: Grade Spiritual King.
7: Grade Spiritual Emperor.

These, in turn, are divided into 3 Stars (Alchemist of 1 star, of two stars, of three stars...).
External Spiritual Weapons are divided into the same number of Ranks:
Common Rank.
