Hero
Sure, adventuring is dangerous, but if you could go from zero to almost godlike hero in 32 days, then I think more people would do it. Think how many people take up risky careers anyway (for far longer than a few weeks) without this promise at the end ("Shall I join the army? On the one hand, I'll be put in a dangerous posting, far from home. On the other hand, it's only for a handful of weeks, then I'll get to retire if I want, and be able to cast Wish spells. I'll have so much power I'll be as close to immortal as anyone can get, and I'll easily be able to influence world events. Hmmm, I wonder if I should do it."). I think you'd get more than a few takers.
Only if you have a godlike DM pulling strings for you to make sure that every day you encounter exactly the right number of monsters to fill up your "quote" from the XP chart in the DMG. (And they have to be solo monsters too, because large groups will fill up your quota at 4x the rate without granting 4x the XP.) This can fail in two ways. Either:
1.) you don't meet enough victims (er, "foes") and so spend a year hunting orcs on the frontier, averaging 1 orc per day with only 36,500 XP at the end of the year, or
2.) you accidentally meet the beholders and vampires on day 5 of your adventure when you are still level 4, instead of on day 18 when you've already killed dozens of trolls and bulettes and giants and are now level 13, and the beholders and vampires unceremoniously kill you.
#1 seems far more likely to me, especially if other soldiers before you have already depleted monster stocks. Liches may be a renewable resource due to phylacteries, but giants and beholders are basically nonrenewable.
