On Earth.
At that moment, Son Gohan was sitting in the living room, chatting with Eliza, while Fangfang played by herself nearby.
Son Gohan had gotten used to this by now: Fangfang hadn't grown any taller in all these years.
By all rights, Son Fangfang should have been twelve years old by now, but physically she still looked only about eight.
Even his younger brother, Son Goten, looked older than Fangfang now.
Because of this, Son Gohan had once taken Fangfang to the Musli Empire's top biological research institute for an examination. After all, Bulma wasn't particularly knowledgeable about biotechnology.
The results of the various high-tech tests showed that Fangfang's genes had clearly been modified by outside forces. The culprits were those people Son Gohan had already thrown into the trash.
The modification meant that Fangfang's strength would continue to increase over time, even without fighting. In that respect, she was much like the Legendary Super Saiyan.
This seemed to be a combination of the potential inherited from Son Gohan and Eliza.
Further tests also revealed that Fangfang's genes would change under certain conditions—namely, when the energy inside her body erupted.
Put simply, even if Fangfang reached the mental age of thirty, as long as she wasn't fighting, her physical age would remain around ten.
But if a battle broke out, the surge of energy stimulating her body would quickly transform her into a physical state of around eighteen.
Of course, this was also thanks to the special Saiyan genes in Son Gohan's body, which kept him in his prime for a long time to preserve his fighting strength.
Son Gohan could only accept his fate. He was going to have a daughter who would have a hard time growing up.
