Hello guo gui, welcome to the forums!
After drinking the Soulstorm brew, go to the screen where there are the three/one mines.
Abe can't possess his farts, but he can still fart. So, what you have to do is to bring Abe close the first mine and fart. After that, run away!!! the fart will explode after 5 seconds, destroying three mines. Now the path is cleared.
Another aprroach is to drink a bottle of Soulstorm brew and fart just below the red orb close to the vending machine. run away and wait 5 seconds util the fart explode and destroy the red orb. Now Abe can drink, fart and possess his farts!!
Good luck, and stay away from hungry slogs
