The Northern Region's twenty-three countries, the fourth calamity.
The fourth calamity was a city, originally belonging to Songxu Country of the Northern Region but now independent, becoming a country within a country, beyond the control of Songxu.
The city was teeming with reincarnated immortals, spending their days either gathering for brawls or group fights.
Songxu Country was powerless in this matter; the reincarnated immortals possessed formidable cultivation, averaging the Refining Void Realm, and were not short of Powerhouses at the Integration Period. In the Great Human Tribe, they could hardly cause a stir, but in the twenty-three small countries of the Northern Region, they were like a plague of locusts.
An Integration Period Cultivation was enough to become an elder in Wuzhou Emperor Sect, so you can imagine the damage they did to the small countries.
Where locusts pass through, no grass grows, and even the earth can be hollowed out to three feet deep.
