My Avatar Is Becoming the Demon King of Destruction

Bai Xi lived an ordinary life for eighteen years. It was not until he awakened from the system that he discovered that all of his family members had extraordinary abilities. The father who sits on the sofa and reads the newspaper every morning is the most powerful superhuman race in the country, nicknamed "Dusk". The gentle and virtuous mother is one of the core cadres of the mysterious organization Tarot Society, codenamed "Lover". The eldest brother who is studying in college abroad is the face of the Super League Association and the most popular superhero "White Arc" in Li country. The second brother who talks about everything every day is an S-class executive of the United Nations' "Multi-dimensional Administration", known as "Hei Wuchang". The quiet and silent sister is the "Mirror Princess", the ace killer of the international killer organization "Black Crow". The noisy sister is "Star Blue", the new star of the Magical Girls League. Even the lonely brother is a young dragon who escaped from another dimension. Looking at the goal given by the system [extermination of all superhuman races in the world], Bai hope fell into a long silence. It seems that before becoming the Demon King of Destruction, she must first be a dutiful daughter.
