Roshi's Training

Quest Overview:

In the training sequence, you must wake up early in the morning traveling across neighborhoods and communities delivering bottles of milk, swimming laps in a shark infested lake, pushing boulders, and last but not least, finding a pebble in a jungle within sunset.
