One part of Kemun's words really stuck to Vaan like glue. It was something he had thought about before but wasn't sure. After all, it was just one among many possibilities he thought of based on limited information.
But now that he had more information, this possibility had increased greatly and couldn't be ignored.
According to Empyrean Scarletsea, spirit energy was a fundamental element of life. Where there was life, there would also be spirit energy. One did not exist without the other. Vaan had also learned that an unknown force was devouring all the spirit and divine energy in the world.
That was why it seemed like spirit energy had never existed.
This fundamental energy, which cultivators from the Divine Realm used to advance to the peak of life, was robbed from Pangeans, preventing their growth and development in the field of spirit energy.
