I recommend I Have Countless God-level Backgrounds to you! The protagonist of this novel had activated the all-purpose system, which could modify all the laws of the world and create all kinds of mysterious backgrounds. He had activated many powerful backgrounds in the process of reaching the peak of the city, such as the life-and-death friend of the Wanhao Group's chairman, the future son-in-law of the martial arts family in Feng Du Province, and so on. The protagonist had a strong background from the beginning, so it could be said that it satisfied your needs. I hope you like my recommendation.π
