How Many Drops of Water Are There in an Ocean

One flash was one hundred thousand years!

This was the Six Flash Disaster of the Antecedental Spirit's third disaster. The power of this disaster could affect all forms of life. They would reach their end, and even if Antecedental Spirits seemed to have endless life, they would still be affected. Besides Ancestral Spirit who had went through nine spirit ascensions to achieve relatively eternal life, every single form of life would still reach the end of their life at some point.

This disaster did not seem powerful, but it was predominated by the power of time. It was used as a millstone, and it would reduce all forms of life into ash in the passage of time.
