In his previous life, Zhou Yu was an internet tycoon worth billions, yet he died suddenly from overwork, abandoned by everyone and having neglected his family and missed out on the love of his life, Lin Xiaowei. Reborn overnight, he returns to the night in 2008 when he failed the national college entrance examination and tears up his application to work in a factory. Armed with fifteen years of memories of the internet's biggest opportunities, he starts out selling ringtone downloads at a street stall, gathers his brothers around him, and makes up for the regrets of his previous life. He crushes snobbish relatives and business rivals, seizes the opportunities in e-commerce, local services, and short videos, and breaks through the dominance of industry giants step by step. Starting from nothing, he builds his own internet business empire, protects his family and friends, finds mutual love with his beloved, and rewrites every regret in his life.
