At 45, genius architect Lin Mu sold his house to raise funds and help his roommate, Zhao Qiang, establish Xingtu Technology. After eight years of pouring his heart and soul into developing the company's core architecture, he was betrayed and kicked out just as the company was preparing to go public. To pay for his sick daughter's treatment, Lin Mu joined the struggling Yunting Technology as a technical shareholder and rebuilt it with a cutting-edge system. After Zhao Qiang stole his draft and secured a major contract with Tianqiong Group, the system collapsed, exposing Lin Mu's true identity as Zero, a legendary open-source programming genius. Zhao Qiang was imprisoned for fraud, while Lin Mu joined forces with female CEO Shen Yue to build a successful company and take it public, ultimately gaining both professional success and a happy family.
