I will open with a barrage of fungi, (lightly grilled to heat them to a temperature that will render them "sweaty" which i will position just 10 feet from the great wall. Whilst this blizzard of spore rain is going on, i will light the toilet papers, fly them over the wall with my Hydrogen filled hot air balloon, and drop them onto their village huts!!! THEY WILL SURRENDER!!! I KNOW IT. China is overcrowded, but with my cunning plan, they will conceed.
This will be due to the fact that the poeple will petition their government to submit to my authoritaaii, as there wont be mushroom left for people otherwise.........
