The material world cannot possibly contain indescribable entities, or any spectres composed of dark matter, Lu Yuanming was certain of that.
Any intelligent existence within the material world must adhere to the substance itself, even the plasma lifeforms of legend are made of plasma, and this was an absolute certainty without exception.
Matter belongs to matter, and dark matter belongs to dark matter; this line of clear demarcation maps the entire universe.
The only exception is special dark matter.
The stable field that Lu Yuanming could now use to materialize Soul Bodies consists of extremely minute particles of special dark matter.
Similarly, in the memories Lu Yuanming resonated with from the indescribable Martians, he indeed saw some instances where Martian civilization utilized special dark matter.
Those were the extraordinary creatures.
