This Classmate, Please Stop

There is no peace outside the city, nor is it a peaceful place inside the city. In the thirteenth year of the new era, new cities have been built and new rules are being written. The sun still rises. The intertwining of good and evil, the collision of order and chaos, the conflict between Sequencers and ordinary people - are also happening here all the time. From the past to the future, from ordinary people to Sequencers, from North Rock City, which has the worst security, to South Rock City, which he does not want to step into again, from the extremely chaotic West Rock City to the extremely depressive East Rock City... Where will it be next?
