Rebirth in 2005 from Wage Earner to Business Godfather

A 22-year-old graduate was humiliated by his ex-fiancée who broke off the engagement in public in the job market. In despair, he was accidentally reborn back to 2005. With a complete business memory of the next 20 years, he must complete primitive accumulation before the advantage of rebirth disappears - but every increase in wealth will attract more powerful opponents: the family of his ex-fiancée, the stock market forces, and traditional manufacturing giants. The mystery of life experience is like a hidden fuse, which may detonate a greater crisis at any time. He wants to fight his way to a business empire and revenge in an asymmetric war of cognitive crushing and resource scarcity.
