Kasso mainly wanted Sun Wukong to go to North Kai so he could learn the Spirit Bomb. As for the Kaio-ken—
That depended on whether he wanted to learn it.
But Kasso believed the Kaio-ken was no longer of much use to Goku.
Not only did it consume a tremendous amount of stamina, it also placed an enormous burden on the body. The multiplier it provided was nowhere near that of a Super Saiyan!
At this point, it felt somewhat pointless!
Time passed quickly, and just like that, two years went by!
Planet Sadala had not been attacked by Towa's group. Bardock and Garis remained on the planet, and nothing had happened to them!
As for Sun Wukong and Vegeta, their power levels had surpassed ten million, yet they had not been attacked either.
This left Kasso somewhat puzzled. He always felt that Towa and the others were holding back some kind of major move.
During these years, Sun Wukong also followed Kasso's advice and went to King Kai to learn the Spirit Bomb.
Somewhat unexpectedly, Sun Wukong learned the Kaio-ken as well.
According to Sun Wukong, these were his final two trump cards. If he encountered an enemy he could not defeat, he could risk his life by using the Kaio-ken while transforming into a Super Saiyan!
But if he did that, the terrifying burden would cause his body to collapse instantly afterward. Whether he would have time to eat a Senzu Bean would depend on whether one had been prepared in advance!
Otherwise, with such a reckless power boost, he would have no hope of survival at all!
Unless he broke through to a state beyond Super Saiyan God!
After all, Godly Aura could nourish and strengthen the body to a certain extent. Just like Sun Wukong
