The greater the number of believers, the stronger their faith, and the greater the worship; it would result in a strong Deity.
Conversely, if the number of believers dwindled, the Deity's strength would take a sharp hit. So in this power system, none could take a resolutely strong position.
After all, the strength of a Deity depended on the strength of its people. So, even if Compass Carburettor were to become exceptionally powerful, once he clashes against his enemies, his people would take a hit due to the war.
Through war, their numbers would be reduced, which would directly weaken him. Considering how there were four enemies, even if Compass Carburettor were to grow to become the strongest in this world, he would be brought down on his knees.
