Looking at the semicircular training room, just like the one in the story, Hao Shuai couldn't help but marvel. Dr. Brief, Bulma's father, truly was the founder of the Hoi-Poi Capsule Corporation and one of the two greatest scientific geniuses in the Dragon Ball World, alongside Dr. Gero. He'd built the Gravity Room in just about a week.
"Come on! Let's go inside and see how it is!" Dr. Brief said, opening the Gravity Room's door.
"Mm!" Hao Shuai nodded and followed Dr. Brief inside.
The Gravity Room was completely empty, with only a control panel near the door.
"I've set up three buttons here," Dr. Brief explained, pointing at the panel. "The top one increases the gravity, the bottom one decreases it, and the middle one cancels the gravity setting entirely. Since this is a brand-new invention, the maximum setting is currently twenty times normal gravity."
"Mm! Thank you very much, Dr. Brief!" Hao Shuai said gratefully.
"Hahaha! Oh, it was nothing. We're family!" Dr. Brief replied with a laugh.
Hao Shuai didn't say anything more, but asked if they could continue increasing the gravity later. He also suggested the idea of a Gravity Bracelet.
"Twenty times normal gravity already pushes the limits of the most advanced materials in the world," Dr. Brief explained. "To go higher, we'll need better materials. I'll have the company step up its research."
"Then thank you, Doctor. I have a few hundred tons of gold that I'd like you to handle for me. Please use it to fund the research into new materials." Hao Shuai didn't want Dr. Brief to keep paying out of pocket, and he had plenty of money himself.
