Xero and the two Demon Kings have just arrived in the Underworld. At a glance, he didn't feel anything strange going on there. It was still the usual hell-looking terrain he remembered a few days ago.
The only thing that set it apart was only the demons looked so rare and barely existed within a radius of five
fifteen kilometers from his current location.
"That monster is currently in the eastern sea defense fortress. That one is trying to break into the second layer of our fortress." The red Demon Kings pointed toward east.
"I already know. We're going there now." Xero frowned at some unpleasant factor.
He then flew off towards the east, covering a distance of hundreds of kilometers in just a few minutes. The two Demon Kings tried their best to catch up, but their speed could not match God-level being.
