In the 1990s, young Liu Yuan used his entire savings of 20,000 yuan to buy a dilapidated truck, hoping to make a living by driving a taxi and save up for marriage. However, his girlfriend Wang Fang thought the car was dilapidated and proposed a breakup. While repairing the car, Liu Yuan unexpectedly discovered a golden Buddha embedded with gemstones hidden inside the car, which was worth a fortune. He liquidated it low-profile and successively bought a house, played the stock market, and invested, rapidly accumulating wealth. Meanwhile, Wang Fang and her father attempted to blackmail Liu Yuan to no avail, but instead had their lies exposed. Under the guidance of university professor Zhang Jiadong, Liu Yuan deeply studied economics and stocks, successfully reaping huge returns in the stock market. He also helped the honest and kind mechanic Xiao Zhou and refused the attachment of vain relatives.
