DB Chapter 159
From Dragon Ball Encyclopedia, the ''Dragon Ball'' wiki
"The Blasted Earth" (荒野の大格闘！！, Kōya no Dai-Kakutō!!; Literally meaning "A Grand Battle in the Wasteland!!") is chapter 159 of the Dragon Ball manga.
The explosion continues, and Yamcha wonders why the TV's cut out in their plane. Bulma points out the mushroom cloud up ahead, coming from King Castle's direction. The King and his two guards have just barely managed to escape in a little plane, and the King is upset about the town and King Castle. Piccolo stands in the newly-formed barren wasteland, and laughs about his victory. But then he freaks out, since he can still feel his ki.
Piccolo looks up and spots Tenshinhan in the air holding Goku, and gets pissed about that guy who knows Bukūjutsu still being here. Tenshinhan comes down to the ground, and Goku thanks him. But, Tenshinhan's really exhausted, and Goku asks Ten-san what's wrong. Piccolo realizes using Bukūjutsu just then must've taken the last of his power, and combined with Goku's injured leg, Piccolo thinks he has this won.
Piccolo starts powering up, and says not to mess with his Bakuriki-Maha. This time, Goku's not going to wait it out, and he rushes at Piccolo and hits him in the stomach. Piccolo is only affected for a short time, and Goku realizes he has less power with only one leg. Piccolo then launches his his Bakuriki-Maha, and Goku shields himself to take it head on.
There's a huge explosion, and Tenshinhan is down. The smoke clears and there's a huge hole in the ground where Goku was, and Piccolo thinks it's all over. "K-Kinto-Un...!" Kinto-Un whooshes over to the hole, and comes back up with Goku hanging from it. Piccolo can't believe it, and Goku says Piccolo must be losing his strength after all. Piccolo refuses to believe he, Piccolo Daimaō, could be opposed by a mere human, and Goku says since he has a tail, he's probably not human. Goku says he's also lost most of his strength, so they'll just battle it out to the death. But Piccolo won't have that, and he reaches over and grabs Tenshinhan by the head. "Alright then, try moving!! I'll smash this guy's head if you do!!"
