A long, realistic urban business-war saga. Set against the backdrop of two decades of rapid development, it follows a rich heir who loses everything and fights his way back, from the study-abroad boom and the mobile internet gold rush to the capital winter, the collapse of guarantee chains, and the digital transformation and global expansion of industry. Its tone is sober yet resilient: brisk and sharp early on, stark and cutting in the middle, then weighty and bright in the end. It neither shies away from cruelty nor peddles despair. At its heart is the question of how people rebuild on the ruins.
