420 Is That Valid?

Back at the Formations Guild, Rean was finally hindered by the next formation. When Rean touched it, the barrier in front bent outwards. Still, there was a limit as to how far Rean's hand could go before he couldn't force it anymore. 

'This protection formation looks a bit elastic. I was lucky that the last formation used a hidden core approach, so breaking through it was simple. This one, however, has its core located inside the formation itself. They didn't even try to hide it. After all, it would have no meaning once you pass through it.'

Nonetheless, Rean's Light Element was still outstanding when it came to analyzing formations. After all, they're real paths that the runes can't hide since they need spiritual Energy. It's just that Rean would need to break it like everyone else after finding the flaws to exploit.

'Sister Orb, how many have reached this second formation already?'
