Earth.
After Lin Chuan brought Son Gohan and Piccolo back, Bulma spent another two days buying all the supplies they needed.
They could have left first thing in the morning, but they had spent those extra days so they could enjoy a more comfortable interstellar trip.
Actually, only Bulma and Chi-Chi needed that.
What did a long interstellar voyage matter to Lin Chuan, Piccolo, and Son Gohan?
Even if it took a long time, they would just spend it training.
Besides, this trip would only take five or six days to reach its destination.
How had they determined the exact location of Planet Namek? Naturally, they had found its precise coordinates in a Frieza Force spaceship.
In the Original Work, they used the coordinates King Kai provided, then took the spaceship Piccolo had arrived on years earlier.
Now that Lin Chuan was here, there were plenty of ways to find the location.
Even if it hadn't been in a Frieza Force spaceship, he still knew exactly where it was.
After all, he had spent a long time researching it in his previous life.
The fourth planet in Vega Constellation's 27th star system. Its coordinates were SU83 and 9045XY.
Chi-Chi was going too?
Of course!
In the Original Work, Son Gohan went with Bulma and Krillin to Planet Namek, and Chi-Chi should have gone with them.
But she had to stay behind to care for Son Goku's injuries, and could only bid them farewell through tears.
This time, Son Goku wasn't injured, and no other troubles stood in their way.
Lin Chuan didn't mind her coming along, of course.
It wasn't a big deal, and she wouldn't hold the group back.
All things considered, Chi-Chi going would actually be a good thing, since she could look after everyone on her
