It sounds like you’re referring to a specific fan project, mod, or concept called Dragon Ball Z Team Training v10. Since this isn’t an official, widely published game or expansion, I’ll interpret it as a hypothetical or community-driven update to a team-based Dragon Ball Z training RPG or strategy game (perhaps inspired by Dragon Ball Z: Team Training — a fan mod of Fire Emblem or a similar tactical RPG?).
Then every Z-Fighter’s wrist communicator—Bulma’s latest invention, the "Z-Band"—lit up with a single, glowing text:
Krillin opened his eyes. The disc in his hand hummed, vibrating with the upgraded sound effects of the new patch. "Destructo Disc... Chain!"
