The man's brows furrowed.
Spiritual Power, a mysterious energy.
Unlike Inner Strength and Body Technique Masters, Spiritual Power is intangible and difficult to cultivate.
While Inner Qi and Body Techniques, no matter how difficult to cultivate, always have methods to improve, Spiritual Power concerns the brain.
And the development of the brain, even with modern technology, has seen almost no advancement.
Modern technological advancements in brain research, compared to a hundred years ago, show almost no progress. The seemingly prosperous brain research is merely an extrapolation on the achievements of predecessors, without any substantial changes.
It is under such circumstances that superpower users related to Spiritual Power appear particularly precious and mysterious.
With Spiritual Power, they can induce dreams, give psychological suggestions, and even kill forcefully using Spiritual Power.
