Dong Qianchuan, a top hacker, lies low for three years at Qichen Technology under an assumed name, working as a warehouse keeper while maintaining the company’s entire system. New director Zheng Hongye tries to assert authority, cutting allowances and dismissing his technical contributions. He appoints Yang Su, with a fake diploma, to lead the Huayuan project, triggering a total collapse in the rehearsal. Drawing on profound technical skills, Dong turns the tide and regains influence.

He teams up with others to uncover the truth, weed out internal moles, clears his name, and founds Qianchuan Security, earning widespread respect in the industry.
