Su Yun, a modern social animal, died suddenly after working overtime and became a beggar in the cold winter of Dayong Dynasty as soon as he opened his eyes. Huddled in the corner of the dilapidated temple, wrapped in rotten catkins encrusted with ice, with no food in his belly and no clothes on his body, the moans of hunger and the howling of the wind and snow could be heard in his ears. He has no golden fingers, no peerless martial arts, only a modern brain that has read history and is well versed in the rules of survival. From the embarrassment of grabbing a piece of cornmeal, to the calculation of saving copper coins to buy coarse cloth, from avoiding the bullying of local gangsters, to dealing with the exploitation of squires and officials, Su Yun struggled to survive in the mud. He used modern knowledge to improve farm tools, brew cheap spirits, organize beggars to huddle together for warmth, and stood up from the dust step by step. But in this troubled world, where human life is like a piece of grass and power suppresses all living beings, he must not only protect the lonely people around him, but also protect himself in the turbulent undercurrent of the court. When the remaining snow melts and the road is thousands of miles of mud, a beggar's counterattack has never been a legend, but a road paved with blood and sweat.
