I'm Possessed by a Demon, It's Useless for You to Cry to Death

[Shuangwen, a perverted road to becoming a demon, no need for morality or anything else] Xiao Ling traveled to a world of immortal cultivation, an era where the demonic cult was resurgent, the righteous order was in jeopardy, and people's hearts were floating. Xiao Ling was born as a man of destiny, a natural talent for cultivating Taoism. But when Xiao Ling was twelve years old, the demon sect rose and Xia Kingdom was in danger. In order to save the country, he was willing to serve as a hostage in an enemy country for five years. He was tortured for five years, and his Dantian was shattered. After returning to China, he thought he would return to his hometown as a hero with a loving father and mother. The result is that her father doesn't care for her, her mother doesn't love her, and her younger brother has replaced her as the new destined person, taking away all the halo that belongs to her. Xiao Ling was unwilling to accept his fate, and with the help of the system, he unlocked the demon king's body and stepped into the demonic path. Your treasures are very good, I want them all. You have a good physique, please help me make elixirs. Want me to forgive? Regret it? What does it have to do with me? When her parents, brother, and former senior sister came to beg Xiao Ling to go back, Xiao Ling decisively refused! Morality? Loyalty and filial piety? Sorry, my whole life was ruined by these words. Now, standing in front of you is Lord Demon Lord, whose expression changes in the world! Why should you define what is right or wrong between immortals and demons? From now on, I have the final say in everything!
