Zombies in Dragon Country are ghosts with physical bodies transformed from dead humans due to excessive Yin Energy or resentment.
They usually lack humanity, lose their rationality, and can absorb the Yin Energy from the moon because of their unappeased spirits.
Of course, this is just one type of zombie, which belongs to a transformation caused by a mix of both Yin and Yang.
Generally, zombies transformed in this accidental manner are limited in number.
At most, there might be a few or a dozen.
Moreover, it's extremely difficult for ordinary zombies to advance to Green Zombies.
To become Fur Zombies, it's even more rare—one in ten thousand.
Zombies formed from accidental circumstances rarely become Flying Zombies.
Because the conditions don't allow it.
For a zombie to become a Flying Zombie, it needs the support of the surrounding environment and Feng Shui.
Like the air-raid shelter zombie incident in Ziyang City.
