The power Upanishad in those Demogorgon statues was the essence of the Demon Clan’s best techniques, just like the martial arts, martial spirit, and other power Upanishad of Human Clan.
However, human warriors usually used books and scriptures to learn the inheritance, while the Demon Clan used those statues to gain the pure energy that they were cultivating.
These seven Demogorgon statues seemed to carry kinds of energy and ancient Seals of Upanishad, or some new powers that they had just created lately in the Second Demon Area. New members of the Demon Clan would come here to take the powers. Experts of the clan would visit this place to record the new power Upanishad they had discovered and developed, that the others could come and take it as their inheritance.
These seven Demogorgon statues carried the culture, Upanishad, essence, and the inheritance of the Demon Clan. This place was the cradle of the Second Demon Area, the most precious thing they had.
