"Evolved Demon" 

Indeed. The change on the battlefield only lasted for a few minutes, and soon, new demons continued to pour into the island, just like moths plunging into the fire! 

The warriors who thought there would be hope in surviving until the fairy of space arrived instantly changed their faces. 

Seeing new demons pouring non-stop, as if wanting to conquer the whole island, and most of these demons were concentrated around the castle...the warriors were about to break down. 

They even suspected whether there was something in this castle that attracted the demons so much. 

For example, maybe there was a demon-inducing powder mixed into the structure of the castle or something.... 

If not, how could so many demons from all over the island insist on approaching this castle? 

It was true that many mid-level demons summoned the low-level demons out there to besiege their castle, but this was already too much...
