Fake Zerg: Limited to carbon-based life structures, their evolution relies entirely on exogenous genes, they are unable to maximize the use of organic resources and are basically isolated from the mechanical technology tree.

Real Zerg: Nano-molecular components are designed using genetic programming language for DNA encoding, and each gene expression trait is a sentence.

Continuously absorb foreign species or design various micro-biological tissues or protein elements on their own.

Using cells as assembly factories, various nanoscale biomechanical components are synthesized and printed in a form similar to assembled proteins.

Each individual is composed of countless microscopic bio-machines.

It is not limited to carbon-based life structures and can simultaneously climb the mechanical technology tree.

This is a time traveler who traveled to a foreign starry sky and became the star...
