Chapter 405: Spirit Mechanical Invasion

The spirit blackholes floated in the air. Sound waves, light waves, particle waves… All sorts of energy waves weren't able to spread. They were completely devoured silently by the spirit blackholes.

When the spirit blackholes appeared, they instantly started to devour their own kind. The spirit lifeforms on fire caused by the crimson refinement gunpowder were all devoured cleanly. Nothing was left of them.

The cannons of the Great Wall University fired unceasingly. Metallic cannon artillery shells arced through the air, but the spirit blackholes didn't hesitate and swallowed everything.

Matter was a super stable structure that energy-lifeforms did not have.

Feng Lin understood that the spirit blackholes had highly concentrated energy-structures, to the point of forming semi-material states. This was why they could resist the destructive effects of the crimson refinement gunpowder in their stomachs.
