With Zhang Yi saying this and showing his strength taking more than half of the Dark elves in a few seconds, the other Dark elves began to realize the reality, without more than half the strongest elves and without Falael this place would be easy for the Forest elves dominate even if a war did not destroy this place.
Zhang Yi could say that because he wasn't sure if Gantar and the Forest elves would agree to come with him into his mental energy world, so the Forest elves could really decide to attack this Dark elf territory.
After Zhang Yi said all this, almost all Dark elves agreed to go with Zhang Yi to this safe place and a few thousand elves decided to stay in this territory, so Zhang Yi took the elves who wanted to be saved with him and left the others behind.
