Sickly Liam Lee is reborn back to 1980, burdened with a 6000-yuan debt left by his father. He accidentally gains the Mountain Foraging System, which strengthens his body. Starting as a hunter, he hunts wild boars, fights black bears, outsmarts century-old wild ginseng, gradually pays off the debt, builds restaurants, rewrites his family's poor fate, and rises to become a successful winner of the era! He also meets and falls in love with Linnea Lin, a female member of the Law Enforcement Team.
