166k demons, I've never seen that many before =) Well done! Chinese maps are very specific and clearly not for everyone :)
I would never have made that many, but during this map, our attack/defense stats are around 20-30, while the computer's are 50-70, and the army wasn't enough... plus, there's a very large increase in creatures in all the castles, so you have to put them somewhere! :)
For almost the entire map, I had 10-20k demons. I gathered 166k in the last week before going to the final boss.
