Review Detail of Niuxize in Oh My God! Earthlings are Insane!

The more you read the better it gets. The mc goes back in time with a system which gives points based on the amount of him contributing to society, which will face almost certain doom in the near future. There is little to no face slapping, instead, the mc focuses on the strength of the city and helps his peers by teaching them fighting arts from the future. Very good novel, 9/10
