Bulma paused in her tracks and turned around.
"What is it?"
Son Goku said, "The Dragon Balls on Earth, due to gravity, are bound to land on the ground or on top of something. Since Earth's surface area isn't that large, the Dragon Radar for Earth only needs to be 2D to work; it can cover the entire globe at once, and you can just search by coordinates. But the universe is three-dimensional and vast. Assuming the universe has four directions—north, south, east, and west—you also have to define up and down. Each direction extends almost infinitely. Therefore, the radar you're planning to make for the Super Dragon Balls needs to be a 3D-view radar to actually find them."
Bulma blinked in surprise.
"A 3D-view radar!"
"That's right. I didn't think you had it in you, Goku, but your logic is spot on... This means simply modifying the Earth's radar won't be enough; I'll need to rebuild the underlying logic from scratch, which makes things a bit troublesome..."
Beerus furrowed his brows and asked, "Well? Can you make it?"
Bulma thought for a moment and said, "Now that I have the concept, I can definitely make it, but it will take a bit longer. A 3D framework isn't just twice as hard; it's dozens of times more complex than a 2D one. Plus, to search a wider range, the Super Dragon Ball radar will likely need to be much larger. So, if we want to get the new radar done right, it'll probably take about ten days or so."
Vegeta frowned and said, "Ten days? That might not be in time for the Tournament of Power!"
Son Goku immediately said, "It's fine, if we can't use it, then forget it. We'll just make our wish whenever we find the seventh
