Summary :- Master Roshi wakes the boys up early to begin their training. Their job is to deliver milk, but there are several miles between each house. After several exhausting runs, they are made to climb a mountain to deliver milk to the monk at the top. While at the top, Master Roshi tells them that in eight months, they will be competing in the 21st World Martial Arts Tournament. This encouraging thought is enough to drive Goku and Krillin through the end of their milk delivery. Once the delivery ends, Master Roshi tells them that they will be delivering milk every day until the tournament. The boys are shocked to find out that the milk delivery was only their early morning training, and that they have much more to do every day. Meanwhile, Yamcha is also training for the World Martial Arts Tournament.
