Give This World a Little Shock of Iron Collapse

In a parallel world in the future, the expected common prosperity has not been realized, and the gap between the rich and the poor has reached an extreme. Although mankind has conquered the entire galaxy, class barriers still stand between people, so much so that the unified world is divided into three, six, nine and upper and lower levels. The self-proclaimed Tianxing people at the upper level set up a "Colosseum" in imitation of ancient times for fun; the despised Miaochen people at the lower level were forced to join in order to survive. And our protagonist, Ximing, who has traveled from the prosperous, democratic and beautiful Dragon Kingdom to the present world, will take the system with him to rise in the twilight, and finally overlook the sea of ​​​​stars.
