Su He, a superpower in the last days, transformed into a sin slave sent to the border and took the initiative to choose the soldier Xiao Zheng as his wife. She relied on her wood powers to find wild vegetables, dig medicinal materials, and hunt game, gradually improving the Xiao family's poor family situation. She gradually developed a relationship with Xiao Zheng and won the trust of the whole family. She purchased hundreds of acres of land by selling wild ginseng, introduced high-yielding crops, and led her family to gain a foothold on the barren border. This was in sharp contrast to her compatriot Su Lan.
