Prehistoric Civilization

Lin An is an orphan who came to Mars to mine for a living and worked as a security guard and repairman at the base. An accident led Lin An to discover the secret of the Mars underground. A lost civilization of cultivating immortals appeared before Lin An's eyes, and there was only one spiritual sword left in the entire civilization to record it all. Lin An returned to Blue Star with the Spirit Sword and gradually became the highest level of Blue Star. Lying human beings are caught and studied. The assets of the rich are uniformly allocated. The entire Blue Star has undergone earth-shaking changes. Until that day, alien civilization comes to the solar system again. Lin An broadcast to the world: "The moment of life and death for mankind has arrived."
