Well, it would still take decades until the three races' alliance prepared for the attack.
Back in the Underworld, the twins' group came out of a spatial fissure, being carried by Tapir. They were still somewhat far away from the periphery of the Path of Reincarnation, though. That's because the area outside of it was sealed by formations for safety purposes.
"Come with me." Tapir immediately grabbed Fagund and began to fly toward the Path of Reincarnation.
Rean, Roan, and the other devils could fly on their own, so they just followed Tapir from behind.
It didn't take long until they arrived in another city, Fekis. The city wasn't that big, though. That's because only Elder Devil and some High Devil clans had access to it. No more than a million devils or so could be found inside. There were more devils in this place, but most of them were working inside the surrounding areas near the Path of Reincarnation.
