Looking into the Elixir Sea, Peter Brown found that the energy inside had already surpassed its original level by more than double.
If the Immortal Power layer was merely a way to use strength, akin to a Qigong enthusiast filling their body with power, then the Spiritual Realm was about turning that intangible power into a tangible force, capable of unleashing a powerful Internal Qi Release.
For a cultivator, Internal Qi Release represented a tremendous advancement, almost like undergoing a transformation.
A person of the Spiritual Realm could easily sweep through a multitude of those at the Immortal Power level.
What Peter now saw was just such a scenario: the Elixir Sea brimmed with immense energy, ready to be unleashed with a single thought.
Peter had roughly estimated that using his internal energy for attacks, he could strike a hundred times before being depleted.
