Ninth-Order Immortal Treasure.
Tenth-Order Immortal Material.
Although there is only one order's difference between them and the distinction between Human Immortals and Earth Immortals, in the Northern Domain of the Lower Realm, the value of these two is almost the same, and in terms of practicality, the former is even higher than the latter.
After all, a Ninth-Order Immortal Treasure is a finished item, whereas Tenth-Order Immortal Material is still unrefined material.
The Northern Domain is a part of the Lower Realm, where True Immortals are not permitted to exist, limiting the development of all arts and techniques; elixirs, talismans, and array tools peak at Eighth Order, with no Ninth-Order Immortal Master in existence.
