Li Ming's family sheep farm was forcibly dismantled by Qian Wanjin, his father was beaten and injured, and his fiancée Yinzi also chose to turn to the other party for money. Li Ming retreated to the barren mountain with his father and dozens of sheep, knowing that there was a century-old black spring hidden in the mountain, and once dug open, the flood would submerge the entire village. Therefore, he built iron gates and stored supplies in advance. Soon the black spring erupted, floods swept through the village, and Qian Wanjin and the villagers were trapped outside the barren mountain gates asking for help. At this time, the only safe area and survival supplies were in Li Ming's hands. Facing everyone who came to ask for help, Li Ming welcomed a difficult choice.
