Billionaire tycoon Jiang Wenyu dies of cancer in his early fifties, haunted by the guilt of driving his wife Chen Lan and daughter Nuannuan to their deaths in a 1987 truck accident after years of gambling, drinking, and abuse. Miraculously reborn into his twenty-something self on September 31, 1987 — one month before the tragedy — he seizes the chance to rewrite history. Armed with three decades of future knowledge, an electrical-engineering master's degree, and ruthless business instincts, Jiang Wenyu begins by repairing the family's broken TV, cooking breakfast, and refusing to touch alcohol or cards.

He must win back Chen Lan's shattered trust, outmaneuver predatory in-laws and false friends like the scheming Zhou He, and leverage the nascent reform-era market to build a legitimate empire. As he flips vintage electronics, scouts upcoming industrial zones, and navigates the chaotic opportunities of China's opening economy, every decision ripples toward either redemption or ruin. This is a grounded, character-driven second-chance saga where the greatest profit is a family saved.
