Su Ran was middle-aged and depressed. After being drunk, he was reborn and returned to his college days. Relying on his past life memories, he got a taste of the stock market, turned the tide and won the championship in the campus business competition, and used this to form a company. Along the way, we relied on experience to resolve problems such as product development, competitive plagiarism, and capital suppression. We also met elite partners and successfully expanded overseas markets to glory. Su Ran completed a gorgeous counterattack in the city, gained both love and career, and became a legendary tycoon respected by everyone, enjoying a life of counterattack without brains and cool writing.
