The Emerald Era, as it came to be called, saw powers surge in the 3rd layer.
The massive destruction of the hordes of soulless creatures allowed the demons to actually breathe and establish various safe havens.
In the first 300 years, the soulless still harassed isolated places but major hubs like the Serenity Sect and others had time to form up defenses and even try to reach out to the 4th layer.
No answer came back until the 500 year mark. A massive tear opened and it revealed a horde ready to strike!
They appeared like a black storm and charged ahead only for the aperture to snap shut. Despite the setback, a certain Emerald Immortal also emerged with Radiant Tiers to slaughter as many as they could once more.
It was a trap!
They devastated the horde but over a third of it escaped. The ones that fell were also only partially recovered.
Still, it was a massive success. Sadly, the soulless did not fall for it again.
