After the frustrated middle-aged Li Shanshan was ruthlessly fired from the company, he was unexpectedly reborn and returned to 1995. Faced with the family water plant on the verge of bankruptcy and huge debts, he used his business wisdom beyond the times to start a counterattack. He transformed an ordinary pure water plant and founded the Lingxi Spring natural mineral water brand. With the subversive advertising slogan "a little sweet", he became an instant hit and quickly occupied the local market. In the end, he started his business by selling water, established a business empire, became the richest man, and gained both love and career.
