The realms of gods, demons, and monsters stood in a precarious balance, and their rivalry sparked numerous wars. Since war brought heavy losses and dwindling profits, they eventually signed a peace treaty for several years. But as the God Realm grew prosperous and powerful, it drew the envy of the other two realms, and war broke out once more. Beiyuan Shangxue, the eldest princess of the divine race, discovered the suffering of ordinary people caused by the war while traveling. She proposed uniting the three realms and decided to put forward a ruler whom all three realms could accept, then establish a shared national pact to ensure balance and stability. Together, they set out on a path of no return to achieve this goal.
