how do i get to world 4

Hello, if your stuck and can't get to world 4 and your on world 3(civilization).at the start of world 3, give the girl atleast enough cards to recover 3000-4000 life points. If you can't see her, she will appaer after dueling someone on the world of civilization(win or lose). After that she will give you her cards. Return to world 1 and speak to the ojama, then goto the pyramid in world 2 and duel the next ojama, then go to world three and save the third ojama from blowback dragon. After defeatin blowback dragon a house will appear.enter the house and duel the three different inpachis. Kozaky will tell you to find the treasure of the cave enter the cave underneath the volcanoe and duel volcanic slicer(if not there leave and come back).blazewing butterfly will appear and yo will have to duel him next.Then the spirit of the six samurai will appaer,duel him now.after beatin gthe spirit return to kozaky in the house(give him limiter removal that you won from the spirit of the six samurai. You will have to duel gogiga gagagigo. When you defaet him zokaky will show the next gate to get to world 4. To pass this gate you will need to beat the speed gaurdian 3 times in a row without losing( your life points will be carried over)after beating ferrario you will automatcally warp to world 4!
