"On the path of budō, one does not strive for victory over an opponent... One strives to avoid defeat by one's own self. To do that you must train yourselves on the foundation of what you have learned until now."
Let the Contest Begin!! (天下一武道会はじまる!! Tenkaichi Budōkai Hajimaru!!, lit. "Number One Under the Heavens Martial Arts Tournament Begins!!") is the thirty-second chapter of the Dragon Ball manga. Its anime counterpart is the episode "The Tournament Begins".
The chapter opens with the boys delivering milk throughout the island; this time, however, they have the Turtle Shells on their backs, making the training more challenging. As the months rolled on, their training has gotten much easier, with them being able to finish tasks in record time.
With one month before the World Martial Arts Tournament, the boys show Master Roshi that they can move the giant rock now, much to the shock of the Turtle Hermit. Roshi then explains that the boys are not entering the tournament to win, but to demonstrate the training they have acquired the last seven months. After that, he gives them forty pound shells, doubling the weight they must carry.
As the final month passes, the boys, along with Roshi, are about to embark to South City. After taking off the turtle shells, the hermit asks the two youngsters to jump as high as they can, which is at least two stories high. Now more excited than ever before, Goku and Krillin get into suits to Roshi's own and board an airplane for the city. After taking a taxi to the tournament grounds, the three martial artists finally reach their destination: the World Martial Arts Tournament.
