[System + transmigration + farming + stepmother + general + love of country and family] Nan Guo'er has transmigrated.
She wakes up as the stepmother of three children in ancient times. Her husband is a hunter, and the family is so poor that all they have left is forty-three coins.
The good news: she's bound to the [Everything Recycling and Exchange System].
The bad news: the System only recycles trash.
Broken pottery, scraps of hemp rope, torn cloth, wood ash... She scours the whole village for junk like a scavenger.
The villagers all laugh at her: Lu Zheng's wife must have hit her head and gone crazy.
That is, until she uses broken pottery shards to make exquisite mosaics, scraps of cloth to sew adorable dolls, and wood ash and wild boar fat to make soap that works even better than bath beans.
Everyone falls silent.
Her business keeps growing, and her family's life gets better and better. The three children go from hating her to being unable to live without her, while the cold-faced hunter's gaze grows hotter by the day.
Just as she's about to reach the peak of her life, war breaks out.
Her husband is conscripted, and news arrives that he's dead.
She refuses to believe it.
She closes her shop, packs her bags, takes the three children, and sets out on a thousand-mile journey to find her husband.
Along the way, she fully unlocks the System's true power.
Recycling trash means reclaiming not only waste, but also homes destroyed by war.
The medical camp she builds saves more than a thousand wounded soldiers.
The explosive charges she makes blast open the enemy gates.
With modern knowledge and supplies from the System, she turns a battle that should have been a crushing defeat into the most glorious victory in the history of the Dasheng Dynasty.
