Which novels described the protagonists who had high-level martial arts and a strong background and lived an ordinary life in the city?

I recommend the following two novels to you: " Time Travel, Battle Break, and Dominate the World ": The protagonist accidentally transmigrated to a world where martial arts were respected. His martial arts were superb and he had a background, but he lived an ordinary life in the city. " The City's Ultimate Heretic Doctor ": The protagonist's superpower is extremely strong. At the same time, he is also a doctor. He moves around the city as an ordinary person. He plays the city and the game world. Who can compete with him? I hope you like my recommendation.
