In Search Of Sacrifices

'What seal is he talking about?' Void couldn't help but ask. 

'Remember the War of Gods I spoke of?' Grey asked. 

Void nodded. 

'It was a battle between humans and another race. After years of fighting, a peerless expert appeared amongst humans. It was said that he almost single-handedly stopped the battle. From the look of things, he only sealed the portal.' Grey explained. 

With the portal sealed, no more people from the other race could come into the Aurora Continent, this meant that their opponents will increasingly start to grow weaker with each death. 

More than eighty percent of those from the other race was wiped out after the seal was closed, and the other twenty percent had to hide from the world.
