I Started with an Abandoned Mine, and I Got Rich by Farming Underground.

Shen Yan, a modern facility agriculture practitioner and fresh food storage operator, accidentally traveled to Yinkeng Village in the mountains of southern Zhejiang during the Dajing Dynasty. She became an orphan whose parents died and inherited a closed and abandoned silver mine. The land in the village is barren and the terraces are fragmented, so she can only make a living by farming; but she discovered that the abandoned mines left by her ancestors are warm in winter and cool in summer, with constant temperature and humidity, and are natural underground farms and storage treasures. She started by cultivating mushrooms, fermenting bean sprouts, and storing vegetables, and gradually transformed the mines into off-season planting bases, cave brewing workshops, and fresh food constant-temperature warehouses. She relied on scarce off-season ingredients and unrepeatable cave quality to open up the high-end market and open up the supply chain from mountainous areas to counties to prefectures. In the process, she has to deal with the government's ban on mining rights, squires seizing the mines, bandits coveting it, and peers stealing secrets. She also has to uncover the truth behind the closure of the silver mine thirty years ago, and ultimately revitalize the abandoned Yinkeng Village through "underground industry" and become the dominating "Queen of Cave Business."
