Today I'm showing you a compact and quick Create mod XP farm that uses a cobblestone generator to make silverfish. The farm has a built-in XP farming system and a "build your own" style if that suits your world better. This farm can get you to level 30 in 15 seconds and produces ~750,000 mB of XP per hour (256 levels). The farm fits in an 8x8x10 space and can be expanded if necessary.
i try to make in my worl, i see you video but no working, the coblestone is burning in the lava and no make a infested stone
Well if it isn't working then it seems you haven't watched the video you silly goose!

Look at the position of the speed controller, that is for the fan and invert(+ -> - ; - -> +) it.
