Chen Ran, a dedicated technical specialist who has worked tirelessly for seven years, receives a year-end bonus of just 250 yuan, while Gu Yuanzhou, who excels at scheming and taking credit for others' work, receives 180,000 yuan. Disillusioned, Chen Ran resolutely resigns. His supervisor, Su Mei, and his colleagues mock and belittle him, convinced that he has nowhere else to go. Su Mei forces Gu Yuanzhou to take over the company's crucial Hengtai project, but his proposal is riddled with flaws, causing the partnership to fall through and the company to rapidly decline. Meanwhile, Chen Ran joins a new company as its Technical Director, repeatedly overcomes challenges with his exceptional expertise, secures the Hengtai partnership, and steadily rises through the ranks to become the vice president of a publicly listed company.
