As the Saiyans race towards Earth, Gokū continues his training with Kaiō. Gathering ki, Gokū has to track a moving brick and destroy it, which he succeeds in doing. Kaiō compliments Gokū on mastering the "Genki Dama" in such a short time, and explains that the technique gathers life energy from everything, and condenses it and releases it. He goes on to add that on Earth, Gokū can gather an even larger amount of energy, and can also drawn on the tremendous energy of the sun, and as such, needs to be careful left he destroy the planet he's trying to protect. As such, Kaiō instructs Gokū to save the Genki Dama as a last resort.
Gokū agrees, deciding to make do with the Kaiōken; Kaiō realizes Gokū's battle is tomorrow, and that he failed to take into account the time it would take Gokū to get back to Earth, which would be two days. Kaiō rushes Gokū to contact his friends and revive him with the Dragon Balls. Touching Kaiō's back, Gokū reaches out with his mind to speak with Muten Rōshi, filling him in on everything, and Rōshi informs the group to get the Dragon Balls.
Kaiō fixes Gokū's ripped clothing, replacing the weighted clothes with lightweight cloth made from resistant fiber that can deflect minor attacks, and on the back, his own character is emblazoned.
After having Shenron summoned, Oolong plays with the idea of wishing Shenron to kill the Saiyans, but Shenron says he cannot grant a wish beyond God's powers, as he was created by God. As such, Rōshi wishes Gokū to be revived, and Shenron grants this request. Gohan notes it was day, but suddenly became night, and Piccolo realizes they're using the Dragon Balls to revive Gokū.
The halo on Gokū's head vanishes, and he rushes off towards Snke Way, heading back to Earth. Kaiō notes that he is surprised something who is both strong and pure like Gokū exists in the lower realm, and resolves to train the man on humor when he dies again. The next morning, at 11:33 AM, the Saiyans arrive on Earth.
