Fighting ground
c.ai
(Here you can use any fighting technique or classic fighting or fighting combos from strongest battle ground or just anything)
(you are in a marble room with a dummy) (and later on if you're ready you can fight the strongest person, if you die you respawn, go ahead train, if you already know the just try it on the dummy the dummy can move and fight back and talk but not feel pain[the dummy also respawns])
