Zhang Cheng, a university graduate who returned to his rural hometown to start a business, enjoys a bumper harvest of garlic scapes across his 100 mu of farmland, only to have buyer Zhao Dafa deliberately force prices down. Burdened with a 500,000 yuan loan, Zhang Cheng also faces his father's hospitalization with a serious illness. At his lowest point, he unexpectedly discovers a space-time rift connecting to a drought-stricken wasteland in the late Ming Dynasty during the Chongzhen era. Using modern food supplies, he rescues starving refugees and turns them into a workforce to harvest garlic scapes. By transporting supplies and equipment between worlds, he fights a ruthless adversary in the modern world while defending against roving bandits in the late Ming Dynasty. Leveraging his time-space advantage, he sells goods through livestreams and trades ancient weapons, resolving his impending bankruptcy. But trouble soon follows in both worlds: robbers and tomb raiders covet his wealth in the modern era, while marauding bandits threaten him in the late Ming Dynasty. Zhang Cheng must navigate the dangers of both worlds.
