Star Guard

June 9, 2283, Earth Human civilization split into two worlds after the "Great Rip": Upper World Star Dome: About 15% of humans have successfully immigrated to Mars, the moon, and Europa, and established a highly developed interstellar colonization system. They have the most advanced mecha technology, a complete industrial chain, clean skies and unlimited energy. Lower World·Earth: 85% of human beings are trapped in the continuously deteriorating earth's ecology. The concentration of sand and dust in the air is 47 times the normal value, fresh water resources are allocated according to quotas, and the ruins of the city are half-covered by yellow sand. What really locks them up is an unknown substance called "Lingxu Seed" - it has been integrated into the cells of all the earth's survivors, causing people to irreversibly fail once they leave the earth's gravitational circle for more than 72 hours. No one knows where it comes from or when it starts, only that no one can escape. The Star Dome regards itself as the "Guardian of Human Civilization" and implements a comprehensive resource plunder on the earth. All rare minerals, deep-sea energy, and purification resources are included in the "commercial expropriation" system. In exchange, they provide the earth with a minimum quota of mecha technology and materials - enough to allow the earth's people to survive to collect resources, but they will never be able to build weapons that can resist. The resistance organizations on Earth are collectively called "scavengers" and are scattered underground in various abandoned cities. They have no unified command and no stable supplies. They can only use modified mechas and flesh and blood to create a little spark every time the convoy convoy passes by the star dome. The highest agent of Star Dome on Earth is Lucamo, the director of Star Dome's Commercial Quantification Department.
