In theory, it was impossible to construct Penrose Stairs in three-dimensional space, yet the staircase before him was undeniably real. There had to be some ingenious method behind this trick.
Although this world had all sorts of miraculous martial arts, it generally still followed scientific principles. But when Song Qingshu thought of that thousand-year-old monster, Lord of Light, he became uncertain again.
