Lingtuo was blackened because he was endowed with great power, but he could not control this power, which led to great physical and mental destruction and torture. In the process of blackening, Lingtuo lost his reason and humanity, became ruthless, and began to plunder and kill other lives. At the same time, the blackened Ling Tuo also lost the people and feelings he cherished, making him more lonely and helpless. In the end, the blackening of Lingtuo led to his death and made him a demon that could never be redeemed.
