Cheryl's Chronicles - Great Dao Mother
The years outside kept going by, as more dangers occurred, the Second Calamity bringing forth more death.
Within the seven years that it descended, 40% of the remaining population had perished. That was a lot, considering how the population was well over Quadrillions.
And that was just the first seven years, as time went by, more deaths occurred. By the Tenth year, Hell had finally made its entrance, as beings such as Fiends appeared.
Lesser Fiends and Greater Fiends, beings that could even challenge Origin Gods and Transcendental Gods, could finally make their entrance.
Of course, the Gods were also planning their invasion, just like the Seraphims, and the Divine Spirits. Nobody wanted to let such an opportunity off the hooks.
And they made their entrance soon enough, as the Seraphs also jumping in, and came in to save the population. Unfortunately, more than half of the remaining population was gone.
