The frosty moon realm's combat power comes from a force that changes the molecules in the bodies of its cultivators. In other words, it's a kind of force that can alter the body's chemical composition. This means that the frosty moons can attack and defend themselves, but they can't do it all at once. This is why they're called frosty-moon-rebels, because they can only attack one kind of thing at a time. They can only do it one time, and that's it. They're going to have to kill each other to get rid of each other.
