The story begins with a scientist, Xu Lang (Xu Zheng), who invented a solution (youba, lit. Oil Master, translated as "Supergas") which has the power of increasing the volume of any liquid to which the solution is applied. Such a solution implies great potential profitability if applied to gasoline or any precious liquid. However, he needs the authorization of Mr. Zhou, the biggest shareholder, in order to get further funding from an investment fund. Gao Bo (Huang Bo), who was the classmate of Xu in college and his partner at the workplace, wants to sell the invention to a French company instead.
