So I’ve gotten so far as to live for about half a million years with transcendence and galactic xp. The trick to getting that far is pouring evil xp until you get to 10’000 years. From that point onwards you have to compound your gains with evil xp until you get another chance at transcendence. Keep going till you get 30’000 galactic xp pretty much, with a solid 2 billion evil xp and you’re in good runnings to finally finish the game
