Humanity has entered the early days of the interstellar colonization era. Three hundred years after humans established a new home in Kepler-452b, genetic differentiation technology has led to drastic changes in the social structure. Genetic modification has given rise to ABO differentiation, and pheromone technology has become a new ruling tool. Shangcheng District uses the air circulation system to control the pheromone concentration throughout the city and establish a strict hierarchy. Little omegas Lin Xi and Ji Chenzhou formed a special bond during their adventures, and gradually began to think about where human evolution will go during their adventures.
Intention: Harmonious progress of science and technology and human nature
