Capítulo 1235: What Class To Choose.

Legion-8 is a no-go since he hasn't hatched yet. Legion-7 couldn't assimilate the tree father either because of the god fire that he bears. The god fire of gods is one of the things he is vulnerable to. He's extra vulnerable to it since he doesn't have a physical body. Anything that comes in contact with a god fire burns including him. 

Legion-7 did what he could do for now. He spread some of his tentacles into the mind network and into the clones he could access for now. Soverick is one of those clones. The tentacle entered his soul through the soul sphere and began assimilating it.

Then it also extended to his body. This all occurred without anyone knowing. Not even Hadrick realized that Soverick was being replaced. Only one world god who had an eye that could identify secrets could tell that Soverick was not a battle sage monkey anymore.
