The entire Capital City of the Nether Realm was sealed! No one could teleport inside the city or teleport outside! It was almost impossible to sneak out!
The Undead Clan utilized all the members they had left in the city. The other two clans had no idea what the Undead Clan was doing.
It was only after they found out that an outsider had sneaked inside the city and the Soul Land did they react and send people as well!
No one was stupid enough to think that the outsider appeared at the same time as Gabriel! It was clear to see that the two sides were working together. It even made them feel as if Gabriel intentionally made them find out his whereabouts since he wanted to weaken the City and make them lower their guard!
Unfortunately, it was too late for the realization. They didn't have a single clue that the people they were trying to find had already left the City.
