I Have a Random System at the End of the World

"The doomsday random system binding is successful." "Host, congratulations, you have received the novice reward. Please choose one of the following four rewards:" "1. Fifty kilograms of gold bars." "2. A set of doomsday survival books." "3. Desert Eagle with unlimited bullets." "4. Fire power." I chose the fourth option, but the system god chose the first option for me!
