North Blood Base...
When Joe heard this name, his pupils suddenly contracted with fear.
This was a region in the extreme north. There was a volcanic canyon covered in endless snowy mountains.
The canyon was steep. Just from the surface, it was very narrow. However, if someone entered through the lava entrance at the bottom of the canyon, they would feel like they had entered a different world.
It was a group of castles built by countless ancestors.
There were many super killers from all over the world. They were supported by many super-rich families.
They trained in an extremely cold environment, endured the temperature that even special warriors could not withstand, and constantly practiced killing techniques. It was hidden behind the mercenary world and the assassin world, and it was one of the three great Evil Worlds. It was called North Blood Base!
The other two places were South Sea Base and East Island Base.
