Doomsday Natural Disaster, Bound to Survival Management System

The natural disaster came silently, and Ye Fei immediately rushed to the supermarket to buy like crazy with everyone when he realized something was wrong. In the supermarket, two people next to her got into a fight over a piece of ham, and one of them's head unexpectedly fell into her arms. Looking at the blood stains on his clothes, Ye Fei felt a chill in his back and realized that some people were "getting stronger" Survival of the fittest, that night, the official broadcast said that three out of 1,000 people had "physical enhancements." Ye Fei waited for three days but did not see any signs of strengthening. Feeling that her body was on the verge of reaching its limit, she walked outside again with the idea of ​​​​fighting to the death. At this moment, she was bound by something that claimed to be the "Survival Management System". She can exchange experience points and systems for supplies, such as—— A glass of Coke with ice in the high temperature of 50 degrees. When the fever persists, a life-saving medicine is available. In the white snow, a bowl of steaming wontons... At first, Ye Fei's experience value was pitifully low, and the things she exchanged from the system were only enough for her to barely survive. Later, as Ye Fei gained more and more experience points, she put the exchanged items on sale and gradually started running the business. Like a snowball, her business scope is getting bigger and bigger, and the experience points she earns are naturally increasing. Under natural disasters, others struggled to survive, but she started a business while surviving. Countless people bought life-saving supplies from her and saw the dawn of life. Later, people often said that Ye Fei's existence itself was a symbol of hope. . Intention: Work hard! God rewards hard work!
