Right now, Lu Feng's cultivation realm was at the First Layer of Celestial Immortal Realm, and for the first three layers, raising his minor realm by one level required ten trillion experience points.

Moreover, according to Lu Feng's estimation, the Origin Immortal Qi in his possession would be enough for him to use for at least two to three years.
