It's pretty easy if you do water and grab kabuto/hinata asap to do survival. I managed to clear all 12 survival trial with no losses the day I unlocked the feature when I made my UK character. The first time something died on that character is on the final boss fight for simulation battle (lvl 58 plot instance), because sai's summons deal more dmg than 9tails for some reason in that fight.

For plot.. nothing is stopping you from level freezing a few days to get way overlpowered and plow through the content until you reach scout deadwood forest blue circle in the mid 60s.
