Xiaren traveled to an ancient dynasty. As a time-traveler, he didn't do anything important. He just made the people who were building the city wall drink white rice porridge and pickled mustard every day, and he made the border guards eat braised beef noodles and Laotan pickled cabbage noodles. By the way, he also traveled thousands of miles to capture the invading Xiongnu Chanyu. Xiaren, who had done all these things, never expected that his subordinates would secretly make him a yellow robe and put it on himself when the autumn wind turned cooler.
