The black hole in the sky stayed there for an entire week before fading away.
Within this week, Gao Peng saw no more Mutated people appear. Even the aristocrats of the Mutated Tribes in the dynasties near the other end of the Spatial Tunnel were moving away from this region.
A while later, Mutated people came to negotiate a peace treaty between the two clans. Gao Peng handed these matters over to his grandfather.
The Mutated Tribe had been living in Jiutian Shidi for over 10,000 years, so there was no way to drive them out completely within a short time. This was a long process. Even back then, the Mutated Tribe hadn't just driven the Human Clan away, but spent decades removing most of them from Jiutian Shidi.
After the black hole was gone, a transparent Spatial godhood appeared in its place.
