After seeing Lilith open World Gates and summon these clones, Roy had already understood what she wanted to do.
These 666 clones would fuse together again with the help of the Red Sea Egg! At that time, the original Lilith would reappear!
This was also why Lilith had expanded the Red Sea Egg so much. Six hundred and sixty-six individuals needed the Red Sea Egg to have a large space. But Roy was a little puzzled now. Did the fusion ritual require 666 clones to complete, or was it possible to have more or less?
Perhaps this number has some special meaning…
