Fantasy: Black Turns into a Demon and Creates Purgatory on Earth

As a half-demon with an innate Taoist body, Yang Yi was actually accepted as a disciple by a human monk. He thought that when he met a noble person, he could become the supreme power of the human race! Who would have thought that the sanctimonious master was just greedy for his body and wanted to seize his body and obtain the innate Taoist body. The injured Yang Yi turned into a demon and vowed to kill those who bullied him. The system then appears. The simple and crude choice put Yang Yi on a path of no return to becoming stronger. "Congratulations to the host, you have obtained the Nine Tribulations Immortal Battle Body!" "Congratulations to the host for obtaining the bloodline of the ancestral dragon!" "Congratulations to the host, you have obtained the divine elephant's prison-suppressing power!" "Congratulations to the host, you have obtained the God-killing Spear!" "Congratulations to the host, you have opened the Law of Killing and the Way to Prove Power!" Infinitely stronger, infinitely violent. Yang Yi is getting further and further on the road to blackness, leading the demon clan on a different path. "Tremble, mortal, I will bring my pain to the whole world!"
