My younger sister and I unlocked our systems on the same day? The setting? The nation decades ago. She went for the learning system and married an intellectual. I had no choice but to go with the useless storage space system. Then, I was forced to marry a thug. A very rude and crass one at that. Thanks to the storage space system, I got through a famine and became the village's richest person. My sister's learning system was useless, and she almost died of starvation. Driven by jealousy, my sister seduced my husband and slept with him. To get my wealth, they came up with a plan and pushed me down a cliff.

I'll survive the famine and get rich! You'll live in my shadow forever, as you should!" She was so smug. She was gloating. I took the learning system and smiled to myself. Unbeknownst to my sister, I got rich during the famine, not because of the system, and my dream was to score high on the exam and get into a good college. My sister managed to mess up her life even when she had the better system. Now she took the useless one. I could practically see the misery waving at her down the path.

To cure our daughter's pancreatic cancer, I made a deal with the System, trading the rest of my life for a miracle drug. My husband called me insane to my face, but secretly gave the medicine to his mistress to treat her facial scar. When I was falling apart in despair, he had the audacity to explain: "Vicky has dreams of becoming a star. She's already 24, she can't wait any longer. "Besides, didn't you get that drug by sleeping around? How could a housewife like you possibly get such high-end medicine on your own? If you want to save our daughter, why don't you go whore yourself out again? It's not like it'll kill you, right?" But the truth is, I really don't have another life to trade for another dose.
