Convenience

Agis immediately shook his head as he said, 'That would be a problem. We can't join the Zasfins since it would definitely reveal our identity. Where have you seen this many Core and Soul Fusion Realm humans before?'

He was right. Everyone in their team has entered the Core and Soul Fusion Realm by now...except for Frandin and Xiria, of course. One must not forget that Xiria and Frandin were still in the Foundation Establishment Realm when they separated from Rean, Kentucky, and Roan. 

'It would be easy to connect the dots and tell that we were part of Rean's group back in the Asume Clan.'

Everyone agreed with Agis on that.

Malaka then suggested, 'In that case, do we join the demon beasts' side? To be honest, I think this is an excellent opportunity to see the results of our time in Valaria Swamp. Not to mention that the demon beasts should be as annoyed with the Zasfins as us.'
