144 Summon Shadow Cat & Elite Troop

In the past, Bai Zemin had once asked Lilith about zombies.

What kind of path did they follow? How did they evolve?

Her answer was very simple but extremely clear and without leaving any misunderstanding: "Zombies evolve by devouring other living beings. But they can also absorb mana from the world."

The problem was that when evolving by forcibly absorbing mana from the world, the evolution could not be chosen by oneself just as when absorbing Soul Power from another existence. This meant that the evolution was almost 100% of the time countless instances weaker and a Second Order existence that had evolved incorrectly did not necessarily possess the power of a true First Order existence.
