Things moved quickly too. Troops from various corners of the plane converged at the center of the plane where the divine battlefield is. It is normal divine war protocol that the Celestial Supreme put in place so that the rest of the plane won't be damaged by war. But there's no way the plane will get out of this with a minor injury with a war this big. They might have chosen to fight in one spot but the number of soldiers coming into that spot will cause damage to the entire plane more than physical injury.
There's is more to war than the loss of life. Wars are expensive. They cause inflation in the price of goods and services. The reduction in the labor force will make labor more expensive and will reduce the productivity of the economy. The war will cause financial, emotional, and all sorts of economic losses.
