The previous page only had videos of battles, so it wasn't clear. Basically, here's the trick. In the starting area of the Jesus hero, there are Pandora's boxes, from which 60k+ creatures appear in a stack. When moved to the hero's army, their quantity becomes -1. By experimenting with this negative value, I found a way to extract any positive value from any such stack (you just have to click for a while). This is how I completed the quest for 130 royal jellyfish at once, using 33,333 archangels, although there will be an option to complete it much later. And in the final battle, 500+ azure dragons helped significantly. In short, the map is a tough psychological challenge :)
