MidGard
1) mc still has to use prim blood lines for other elements 2) he was lucky that midgard is rational but others wont necessarily be that 3)so he needs a hack against this so that the 99%integration pb would be solved 4) the midgard serp doesmt wamt to revive 5)what would a dead person want if not life.....probably legacy or someone who fulfills his dying wish 6) so with all these pt in mind i think the mc will be recieving a gift that enable 99% integration with prim bloodlines and at the same time a legacy to complete given by midgard which would overlap with what all such high lev beings might have in common. for eg - searching the purpose or even better searching the truth of the univ like the metal race. Godamn nice job author never had the time to appreciate ur novel because couldn't waste a moment not to binge read it. please keep going am hooked on. peace!!
