29 to 50 in 2 days?

Also, be prepared for Nexon just restarting the event for a week. There's much that points to that, because that solution lets nexon do as little as possible. Then the questinon would be, can you do 1-50 in two days or so?

Simply put
No

If they make people restart from 1-50 then I'm completely screwed

But Nexon won't do that right? right!?
