If they get that divine artifact, they will be able to disassemble it and turn it into the rank 7 divine flesh that they need to become legendary telepaths. This is another reason that they can't give up on Reinfield City and the Edwin family.
Since they are already going to do it, it will be best for them to delay retribution for the Edwin family for now and use the time to prepare.
The more they thought about it, the better their mood became. Even Legion-8, who was greedy earlier, began to feel some anticipation. This is because the best part of their plans for revenge is that they have a lot of tangible benefits to gain from it.
It is true that the pain of others brings them pleasure, but the most pleasurable thing for Legion is growing stronger. This is why they will always prioritize benefits over revenge and will attack anyone who hasn't offended them in order to grow stronger.
