Xu Chen was originally an outer disciple of the Qingyun Sect, and he endured humiliation and heavy burdens for three years just to find out the enemy who destroyed his family back then. He accidentally awakened the attribute panel and could swallow the attributes of all things for his own use. Just as he was getting closer to the truth step by step, Lin Xuan, the eldest brother of the sect, suddenly rebelled, bloodbathed the elder hall, and stole the treasure of the sect. Xu Chen was framed as an accomplice and was expelled from the school after being tortured. In despair, the attribute panel prompts: Devouring demonic energy can unlock the hidden profession "Soul-Eating Demon Lord". In a moment of thought, Xu Chen chose to fall into the devil's path. He no longer pretends to be kind, no longer tolerates oppression, he wants to use the devil's methods to retaliate against others. As his attributes grew crazily, he discovered that his fateful entanglement with Lin Xuan was far beyond imagination - that traitor was actually his last relative in the world.
