Living a life anew, Cheng Xiangnan returned to the year when his destiny was rewritten. In his previous life, his cousin Cheng Wanru impersonated his identity, snatched the job quota at the hardware factory, and even attempted to seize his engagement. Cheng Xiangnan endured for half a lifetime, ultimately ending up lonely and bitter. In this life, he no longer compromises, resolutely rushing to the hardware factory to publicly expose his cousin's scam and reclaim his own future. Faced with biased family members and his cousin's scheming, he does not yield an inch, relying on his physical strength and years of accumulated mechanical skills to stand out in the forging workshop and win the recognition of his fellow workers.
