Preface

  On December 21, 2012, the entire tribe encountered a scouting fleet of Roamers, who were wandering through space, and NASA's Mars probe.

  On September 18, 2015, after a long negotiation, seven million Roam (Roman) people and three hundred million Roam (Roman) servant tribesmen woke up from the hibernation chamber. The Earth Australia Roam (Roman) Autonomous Region was formally established.

  In 2026, Earth's naturals and Roamers formed a joint government, with the first unified political entity on Earth established three months later.

  In 2035, with the help of Roaman technology, the world's first controllable thermonuclear fusion power generation unit was officially put into operation, and humanity's energy problem was properly solved.

  In 2036, the United Coalition issued a comprehensive declaration of nuclear disarmament and large quantities of weapons-grade nuclear materials were loaded into fusion reactors.

  In 2038, the federal government announced the completion of nuclear weapons destruction.

  In 2039, the first extraterrestrial mining team of the United Government entered space. The Roam (Roman) people began to terraform Mars.

  In 2045, the first human-Roam hybrid was born. A tiny minority of hybrids possessed terrifying talents and potential, but most were not even as capable as ordinary Earth humans. The hybrids suffered from prejudice from both species, yet their numbers continued to grow for various reasons.

  In 2053, the Roaman Temple and the Terran Vatican clashed, with a Roaman ritual assault on St. Peter's Basilica in Rome. The first phase of Mars terraforming was completed.

  2053-2064: The 'First Decade of Religious War' breaks out. The Vatican reveals a thousand-year-old secret power, the Roaman temple suffers heavy casualties, and the Earth Union Government intervenes to mediate.

  In 2065, the Roam people raided a well-known Taoist temple in ancient China. The Second Religious Decade War broke out, and the secret forces of major religions on Earth joined hands to counterattack. The Roam people's temple was heavily damaged, with more than half of its priests killed or injured. The United Earth Government intervened to mediate.

  In 2078, Roaman immigrants and Australian Aboriginals clashed over mineral deposits, with eighty Roamans beaten to death by thousands of Australian hoverbikers, marking the beginning of formal conflict between humans and Roamans.

  From 2078 to 2088, the immigration of Roam people and the folk conflicts between Earth humans intensified, with an annual death toll of over 10,000. Due to the innate advantages of the Roam people, the majority of the casualties were Earth humans. The Roam people announced that the environmental transformation of Mars had been successfully completed, and the first batch of Roam immigrants moved to Mars.

  On January 1, 2093, the Roam (Roman) people announced that they had taken over all power of the Earth United Government. The '93 Self-Defense Counterattack War' broke out, and humans and Roam (Roman) people engaged in an all-out war. The Earth Federation government was established on the next day. The Roam (Roman) fleet besieged the city under threat to the newly born Earth Federation, and hundreds of nuclear warheads launched from around the world completely destroyed the Roam (Roman) fleet.

  After the 93 Self-Defense Counterattack War, all Roam people moved to Mars, and a war that lasted for hundreds of years broke out between Earthlings and Roam people.
