Traveling Through the Waste System of Another Timeline

A man of great intelligence and handsomeness. Because of a misunderstanding in my freshman year of high school, I dropped my studies and spent more than ten years traveling between construction sites. Suddenly one day, after he wrote down the answer to an additional question on a math test paper, he found that when he finished writing the last word of the answer, he traveled back in time to the opening ceremony of his first year of high school fifteen years ago. And the system was awakened at the same time, but it was a waste system. The first fifty owners were pissed to death by it. This novel and its characters are purely fictitious.
