Traveling Through Time in Seven Days, I Stock up in Advance to Avoid the Disaster Year

[Hoarding + Disaster Escape + Business + No CP + Cool Articles + Counterattack] A bad family of origin, betrayal by her boyfriend and best friend, a rubbish job with only one day off and unpaid wages... Who has loved whom in these bad days? Just when Tan Zheng was about to end everything, he accidentally bound the stocking system. The system told her that in seven days, she would travel to the ancient disaster years. As a result, Tan Zheng began to use different methods to cash out, frantically raiding and hoarding goods. Having enough food and clothing is just a basic thing. The modern goodies she brought out easily attracted the rich and powerful. High-yielding seeds saved the people from hunger. Medicine made her a living god that everyone respected. These are nothing. The knowledge she learned from books is the real dimensionality reduction blow. Treating plagues, releasing floods, and even doing business... Just when Tan Zheng was reaching the peak of her life step by step, her ex-boyfriend and best friend who betrayed her also walked in? He even knelt in front of her, crying and begging to be taken in. Tan Zheng smiled slightly: "Stop kneeling, I don't accept waste."
