"The Effects of the Super Holy Water" (超聖水の効能, Chōseisui no Kōnō; Viz "A Drink of Water") is the eighty-ninth chapter of the Dragon Ball manga.
As Gokū is shocked that it took Muten Rōshi three years to obtain the Super Holy Water, the boy comments that he does not have that amount of time and becomes determined to take the water from Karin. The young boy then uses after images in an attempt to deceive Karin, but the hermit then counters the technique to land a hit on Gokū.
As Karin marvels at Gokū's prowess, he informs the young boy that everything he had done up to that point beginning from climbing the tower has trained his body. The hermit then obtains the boy's bag of Dragon Balls and throws it off the tower, causing Gokū to have to jump down to grab them and climb up the tower a second time. After an exasperated Gokū asks Karin why he would make him climb up the tower again, the hermit informs him that it took him almost one day to reach it the first time, but only three hours on the second trip, proving that Gokū's body had indeed been trained.
Gokū still finds himself unable to obtain the water as the sun sets and through the night, and Karin decides that he and Gokū should rest for the next day. Gokū later wakes up and is tempted to take the water while the hermit is asleep, but opts not to cheat. Unbeknownst to the boy, Karin was aware the entire time, and was surprised at the boy's honesty.
Into the next day, Gokū eventually obtains the water, taking him a total of three days to secure it. After the boy drinks the water, Karin reveals that it was no different from any other water, and claims the process of climbing the tower twice and stealing the pot of water from his possession was the entire training regimen, which elates Gokū. As the boy leaves, Karin hypothesizes that the young boy had already surpassed his master, Muten Rōshi.
