Being stabbed in the back by his most trusted brother, Song Yu was reduced from a billionaire boss to a prisoner, and then opened his eyes and returned to the green train in 1990. The opportunities that I missed in my previous life have now become famous. He dumps steel, eats the Sino-Russian border trade line, and intercepts orders from Hong Kong businessmen. He specializes in hugely profitable businesses that others can't understand. While his opponent was still shouting at the street stall, Song Yu had already used his train leather to make millions a day. In this life, everything owed to him must be paid out with interest!
