Once Piccolo had arrived and started training with Goku and the others, it became a little bit harder for the kids to join in on the training. This was due to them being unable to handle the 5 times gravity that the machine generated. There was one time when Bosa run into the chamber with the other three running behind him. All eager to play with their papas and uncles.
Though they were excited, that excitement turned to worry in a flash. Bosa hadn't expected today to be a 5 times gravity day. After all, they did set rules in place so this sort of thing wouldn't happen. But Bosa was currently getting the full effect of 5 times gravity…
Bosa coughed. "That's not 2 times…"
Ushichi shouted, while also using her arms to stop the other two from entering the gravity field. "Big brother!"
Chichi, who had been looking for the kids, came in and turned the gravity down, once it reached 3 times gravity, Bosa was able to push himself back up off the floor and get out of the gravity field.
"Goku! Why did you have the setting at 5 times! Bosa got hurt, and the kids are upset."
"Huh? Oh, we were training at 5 times gravity? I couldn't feel the difference."
"Alright, that's enough! I want to know who it was that set the chamber higher than the scheduled amount!"
Piccolo winced and recoiled. "Uh… I set it to 5 times today…"
"Oh! And look here, the newbie thinks he can set the chamber just because he wants to!? Well guess what mister! Apologize, and do it now!"
Piccolo was dumbfounded at the moment, he really did only know the one setting. While Chichi was waiting for an answer, she squatted down to look Bosa over for injuries. "I swear, whatever injuries you got I'm going to beat into him, ten fold!" That's when she noticed that Bosa wasn't actually injured, a little sore maybe, and then… "Bosa, your Qi… Your special Qi I made for you on your birthday. It's got a tear where you fell off the platform…" She then glared angrily at Piccolo.
This was Piccolo's chance, he raised his fingers and a magical beam hit Bosa, mending his outfit. "I set the chamber to 5 times. I didn't realize there was a schedule…"
"Well, it's a good apology. You'll get off this time. And for future reference-" Chichi spoke with that killer smile… "There's a schedule right there. Now then kids, let's go help Bulma out in her lab."
Once they all left, and the door behind them shut… Piccolo along with everyone else took in a deep breath and exhaled.
"She's fiery as always. So protective of those kids. You'd better be careful around her, Piccolo. She's almost as strong as Krillin."
"Yeah, I noticed that, Goku. How do you deal with such a… How do I say it, a passionate woman bossing you around? She's terrifying."
Goku giddily chuckled. "She's strong, and spars with us regularly. Though that's only when Bulma is in charge of watching the kids."
Days became hectic as time began to fly by. And the day came when Bulma had an idea. One she ran by the other parents first of course. In the end, permission was given for Bosa and Ushichi to do whatever this mysterious idea Bulma had was. The reason why Gohan and Chosho weren't allowed to go on the trip was pretty obvious at face value to those who could sense ki… While none of the children were weak by any means, Bosa and Ushichi had reached a level that the other two didn't.
"Alright you two, I think you're ready to go out into the world on an adventure."
Bosa and Ushichi looked at each other, blinked, and then their eyes widened with sparkles, turning back to look at Bulma. "REALLY MOMMY!"
Bulma nodded with a big smile on her face. "That's right. Both of you are way stronger than I was when I went out. And it'll give the two of you the opportunity to use your skills in practical ways, and help people out. And to give you all a goal to shoot for, take this with you, it will help you locate the orbs I went looking for when I was younger. And it just so happens to be how I met Goku."
"Wow mommy, you mean we can go on a search for the dragon balls! Hey, look, it says there's one right here?!"
"Oh really?! Where could it be?"
Bosa and Ushichi followed the signal, floating in the air as they did. They were both playing along but they knew that the ball was on Gohan's head.
Ushichi giggled, pointing and poking. "Hey, Big Brother Bosa I found it. I found it! It's great grandpa, on Gohan's head!"
Bosa giggled along with Ushichi. "Yep, brother Gohan had the first ball. We're supposed to help those who give us the dragon balls. So… Family hug!"
Gohan giggled as he was swarmed by the sudden hug. The kids loved to play around. And were all really close, so being apart for so long would be difficult. Anyways, the next morning came, and the brother-sister duo flew out in the early morning after a hearty breakfast, leaving behind the 4 star ball, saying that Gohan should hold onto it for when they come back.
"Alright, I assume you're ready too…"
"Yes, I am. I'll do everything in my power to let them grow, but intervene if necessary."
"You had better do just that! If anything happens, oh I swear I'll never forgive you."
A third person flew off following the tracker inside the radar that Bosa had.
All in all the adventure seemed to go well. "Those two seem like they're really close. That's good, at least something good came of my screw up…"
A few days later, the pair arrived on a farm quite a distance away from where Master Roshi lived. Though, not too far away that if the need should arise, it was possible to fight and retreat, to get back up. Though, he could have never expected what transpired next… It was Age 761 October 12th very early in the morning when Bosa and Ushichi started helping the farmer with his work, this was of course in exchange for the dragon ball.
