Starting from a Short Staff, Grinding to Become the Ruler of the Universe

One hundred thousand years ago, Blue Star produced countless powerhouses who could traverse the universe with their physical bodies and detonate stars with a single thought, dominating the cosmos while ten thousand races submitted to them. Until a hundred years ago, a vast number of powerhouses fell and the ten thousand races rebelled. Large swathes of human star sectors were occupied, forcing the human race to shrink its battle lines and maintain a grueling defense. As for those who were unable to evacuate their planets in time but luckily survived, they became Wanderers. Jiang Cheng woke up to find that he had become one of these Wanderers, living in the slums with his grandmother and struggling to make ends meet by selling roasted sweet potatoes at a stall. Fortunately, he obtained a Proficiency Panel, where hard work yields rewards. Thus, starting with a short stick, step by step, he will grind his way to becoming the Ruler of the Universe!
