A bright yellow crystal was wrapped in several layers of mechanical containment force fields.
It was one of the first batches of spoils of war sent back from the frontline by the Clear River Allied Legion.
The crystal was not large, yet extremely faint ripples of devouring continuously emanated from within it.
Even though its original owner had already fallen, the energy within the surrounding containment fields was still slowly draining into the crystal.
The high-level beings of the Mechanical Civilization responsible for receiving the sample did not immediately open the containment.
Large numbers of scanning rays descended from different directions, recording the bright yellow crystal's rule structure, energy fluctuations, and its abnormal connection to the surrounding starry sky.
