A long story about realist business war in the city. Based on the background of the rapid development of the past two decades, from the overseas study boom, the mobile Internet trend, the capital winter, the explosion of the guarantee chain to the digitalization of industry overseas, it writes about the process of a rich second generation regaining themselves after losing everything. The tone is heavy and tough: the early stage is brisk and sharp, the middle stage is cold and biting, and the later stage is thick and bright; it does not shy away from cruelty, nor does it sell despair. The focus is on how people rebuild on the ruins.
