Ling Xiao traveled to a dark world shrouded in the shadow of an evil god. He was chosen as a sacrifice at the beginning and was about to be sacrificed to the ancient evil god. However, at the last moment of the sacrifice, an unexpected change happened! He did not die, but instead awakened the blood of the demon god that was sealed in his body, and became the thirteenth demon emperor who had been sleeping in the abyss for thousands of years!
But this Demon Emperor's role was not easy at all. The demon's body is broken, its strength is weakened, and it is surrounded by the laws of the abyss and countless dark forces that covet the position of the Demon Emperor. He must struggle to survive, use the Demon Emperor's identity and power to swallow the evil god's remnant soul, subdue the fallen monsters, and rebuild the order of the Demon Abyss. He walks on the edge of light and darkness, not only to fight against the minions of the evil god that invade the mortal world, but also to suppress the old abyss tribe that is ready to move. He is not a savior, he is just a mortal who was pushed to the position of Demon Emperor by fate. In order to survive and to protect the remaining trace of humanity in his heart, he did not hesitate to get involved in deeper darkness.
When the Temple of Light regarded him as the source of all evil, and when the demons of the abyss worshiped him, Ling Xiao discovered that everything he did was just following the demon contract carved when he was sacrificed. And what kind of shocking secret is hidden behind this contract? Can he escape the shackles of fate and become the true Lord of the Abyss, or will he completely become a puppet of darkness?
