The Weakest Invincible Guarantee System

When Su Fan was shopping in the supermarket, he accidentally got the guarantee system. As long as he bought a certain amount, he would get rewards. "Hello, I'm buying ten packs of instant noodles." Passerby: "Another poor man who can only afford to sell instant noodles." Cashier: "Congratulations, you have received a million-dollar virtual suit designed by a master." Passerby: "I can go here. I won't have to worry about food and drink for the rest of my life. I want to buy it too." Cashier: "Sorry, you didn't win." "How is it possible? Why can he win the lottery?" "Sorry, you are just a non-Chief." This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
