πI recommend you a novel about superpowers in the city, The Supreme Dragon Emperor in the City. The main character, Mu Chen, rose rapidly because he obtained the Bead of Nothingness. When the foreign races invaded, he crushed them all with an invincible posture. He flattened the three palaces, destroyed the six prefectures, swept through nine feet of land, and kept the foreign races outside the natural moat. He composed a song of praise for the city's cultivation gods. I hope you like my recommendation. Muah ~
