Hao Qi had no inkling of how the pillow worked, but its use was indeed much like sleeping. It cast Hao Qi's consciousness into the target's Mind Sea. If used on an Ordinary Person, it would function essentially like a dream-stealing instrument with virtually no difference. Only when the target was changed to a Primal Puppet could this instrument truly unleash its function.
First, it protected the essence of Hao Qi's Spiriton Foundation, ensuring he suffered no harm within the limits of its protection time and magnitude. Hao Qi's time limit was only thirty minutes; beyond that, protection could no longer be maintained. At the same time, any damage he could sustain was quantified as a percentage, and once that threshold was exceeded, the protection would likewise be lost.
Secondly, its function was mental positioning, helping Hao Qi accurately enter and locate the Mind Sea of the targeted existence, while also helping him precisely return to his own Mind Sea. These two functions alone already made it a cutting-edge creation of the Primordial Era.
