😋I recommend the book " Doomsday Coder " to you. The male protagonist also got a system when the end of the world came, but it was a programming system. The male protagonist could use this system to create all kinds of materials to help him survive in the apocalypse and become a powerful character. This book described the male protagonist's creativity and wisdom in the apocalypse. It was very interesting. I hope you like this fairy's recommendation.😗
