The population is growing and the earth's resources are in short supply. The galactic space design team creates humanoids to fight against humans and ultimately reduce the human population, or replace humans with humanoids. In order to win, mankind established a humanoid eradication plan to study and kill humanoids. Outside the Garden of Eden where humanoids live, there is a protective space called the Great Wall, which contains a large number of secret rooms, mazes and other dangerous environments. The second type of humans has also begun to infiltrate into the crowd. Humanity not only has to face the crisis of cracking the Great Wall, but also resists internal disintegration.
Intention: lose humanity, lose a lot. Lose your bestiality and lose everything.
