The Hero Betrayed Me? As A Dark Magician, I Resurrected The Demon King

This was a JRPG-style alternate world. A goddess summoned a hero who would then form a party to fight against the demon king. Chen Deng transmigrated to this world and became a member of the hero’s adventure party. His job class was a [Dark Magician]. With his SSS rank secret technique Resurrection, he contributed greatly to the defeat of the demon king. However, the instant the demon king fell, what greeted him was not the warm embraces of his party members, but instead a pair of cold silver handcuffs. An officer announced, “Former member of the hero’s adventure party, Chen Deng. Due to practicing the dark arts forbidden by the kingdom, he is considered extremely dangerous. He is to be immediately sent to the capital and executed.” Chen Deng looked to his party members for help and saw the faint smiles on their faces. Right then, he realized that he had been set up. He declared, “Since the hero betrayed me, I will resurrect the demon king!” “Resurrection!” Thus began Chen Deng’s journey of revenge.
