Earth had been under the rule of the gods for years. All countries on Earth—except for Huaxia which remained an independent state—had undergone earth-shaking changes.
The biggest change was the religious faith.
In the regions under the gods' rule, the citizens were only allowed to worship certain deities. Other religions were strictly prohibited.
For instance, people who lived in Southern Europe could only worship Greek gods; people in Northern Europe could only worship Norse gods; meanwhile, people in Egypt could only worship Egyptian gods...
As a result, the existing religions on Earth were hit hard. The number of their followers had drastically reduced!
The second aspect was the political structure. In regions ruled by the gods, theocratic power was above all rights. This made the authority of various clerics expand infinitely, while the credibility of governments of all nations was reduced to least.
