Nine hundred years ago, the crown prince of the golden state of Shenjin, the beautiful and merciful God of War, saved a little cursed orphan with scarlet eyes from death, becoming for him the only light in the pitch darkness. Since then, a lot of water has flowed away: the state has fallen, and the prince has been cast down from Heaven three times for his kindness, becoming the despised "god of failures and pestilence" for people. But the boy he saved did not forget his savior. After going through the torments of hell, he tore out his human heart and became the Unsurpassed Demonic Emperor Feng Juetian, before whom the gods themselves tremble. Cold and ruthless towards the whole world, he has been searching for his God for centuries. And so, when the prince returns to earth after his third exile, ready to rebuild an abandoned temple alone, a charismatic nineteen-year-old traveling companion under the false name Jue Yu suddenly appears on his way. The Demon King is ready to start his game to restore his God to his former greatness, surround him with insane devotion and hide him in the depths of the Underworld — where no one else will dare to hurt him.
