Regardless of whether they're zombies or New Humans, the more they consume, the faster they evolve. The things that New Humans consume provide much less energy than what zombies consume, causing zombies to evolve at a rate far ahead of humans!
Eating is just one pathway of evolution for zombies and New Humans. Of course, there are many other methods, just that humans are yet to discover them.
A regular zombie that consumes the evolution crystal of a Level 1 zombie will evolve into a Level 1 zombie. Consuming the Evolution Crystal Core found within a New Human's brain would also trigger the evolution into Level 1. Eating is indeed a path of evolution for zombies.
Considering these three large glass vessels of evolution elixir here...
Yindan Base exerted great efforts to develop this evolution elixir. Any evolution crystals they managed to get were directed straight into the lab!
How many evolution crystals are contained within these three large glass vessels now?
