A war broke out between the underworld and the sky. In order to maintain the peace and tranquility of the world, the heaven sealed the underworld emperor and his underworld soldiers, and shattered the underworld cross that would choose to resurrect the helper, but there was still a trace of dark power in the underworld cross. Thousands of years later, Hades used the little strength he had recovered to put the Cross of Hades back together. The Cross of Hades quickly found the person who helped the Emperor of Hades resurrect. The Hades Emperor used him and several people who were given powers by himself to unseal the sealed army, kill the soldiers stationed on Angel Mountain, and take away the Angel Notes. When the god of heaven heard about this, he was determined to fight to the death with the underworld. The underworld and the heaven started a war again, and the world will eventually be destroyed........... Only wait for them to wake up!
