Chapter 793: Golden Leek!

A small silver cube floated above the totem, gushing out black cloud-like energy.

Evolution energy spread in the nest, covering the Black Spirit Race one after another. In just a short time, the nest was already filled with black cocoons.

With a flash of Mechanical Force on Han Xiao's fingertips, the small silver-white cube obediently returned to his hand, and he wore it back on his neck.

Han Xiao nodded. "Now, I just have to wait. I wonder what the Black Spirit Race will evolve into."

Advanced civilizations more or less controlled secret technology that others could not replicate. The Evolution Cube was a relic of a civilization very close to becoming a Universal Civilization. The technological essence within it had long been lost. Even when it was in Psyker's hands, the Arcane Church could not understand it. Han Xiao had only tested the various parameters of the Evolution Cube.
