Elves are a type of Lifebound Spiritual Beast, and also a special category of Spiritual Beast. For example, the Plant Elf that Chen Jiuge once asked his mother for is one such type.
The Bloodline of Elves doesn't have a clear upper limit. As long as one is willing to invest resources, an Elf-type Spiritual Beast can successfully reach the Seventh Rank. Of course, the resources consumed in this process are immense. Without a significant financial foundation, one would naturally not cultivate such Spiritual Beasts.
However, because of this, it is much more difficult for the Bloodline of Elf-type Spiritual Beasts to reach the Immortal Rank than it is for other Spiritual Beasts.
