I think this is a wrong place to ask!
But what is Qi is it Tc too?
Please help! And Explain

Qi is what you get when you win a battle, so when you get a certain amount of Qi you get a new belt. And when you get enough qi you can buy items that are qi restricted wich means you need a certain amount of qi to use it. Tc is ingame cash that you can buy ingame colours, textures, avatars and other stuff.

Thanks man
By the way thank you also for answering in good way!

Also.
You get even qi even if you don't win the match
