Piccolo's potential was just as terrifying. Otherwise, in the Saiyan Invasion arc of the Original Work, he wouldn't have gone to King Kai's Planet after dying and reached a Combat Power of tens of thousands through his own training in such a short time.
After being revived, he arrived on Planet Namek and happened to find Nail on the verge of death.
Nail's assessment was: "I can't believe you became so powerful. How did you train?"
Then, after earning Nail's trust and accepting his request, Piccolo assimilated with him. His strength surged more than tenfold, reaching—and then surpassing—a million Combat Power!
So even Lin Chuan thought that after six days of adapting to sixty times gravity, Piccolo's Combat Power of just 45,000 was on the low side.
After all, Lin Chuan had helped him and offered guidance, both directly and indirectly.
The only explanation was that he hadn't faced enough pressure or experienced enough.
Breaking through certain thresholds might require special circumstances.
Like truly facing death...
As for Son Gohan, the kid had continued to improve, but his Combat Power had only reached 32,000. That was genuinely a little low.
Lin Chuan had originally thought that Son Gohan could reach at least 50,000 Combat Power by training under gravity and making use of the Saiyans' busted natural talent.
But forget 50,000—even 40,000 proved out of reach. He'd only just passed 30,000.
Of course, that was partly because he'd spent less time training.
Lin Chuan and Piccolo had trained nonstop. No one could make them stop.
Son Gohan was different. For one thing, he was still a child. For another, Chi-Chi kept a close eye on him and wouldn't let him continue once his allotted training time was up.
Lin Chuan and Piccolo couldn't say anything about that. What were they
