Eschatological Evolution

At the end of the century AD 2200, the Alliance of Nations made a huge breakthrough in aerospace technology and possessed space navigation technology. However, other civilizations encountered were not friendly. Eight civilizations united to invade Earth's civilization. Faced with the menacing extraterritorial civilization, the League of Nations did not compromise. But how can the technology and combat power of extraterrestrial civilizations be resisted by the earth's civilization that has just entered the aviation field. The forces of the International Alliance were retreating steadily, planetary bases were lost one after another, and the coalition forces of the eight major civilizations descended on the Earth-Moon System. At the critical moment of national development, the League of Nations decided to launch the BY plan. Project BY is the mutation plan, which spreads mutation powder, the latest research result of the International Alliance Research Institute, to the world. Humans who absorb the mutation powder have a very low probability of mutating, possessing human form and beastman form, with unknown side effects. The combat power of the League of Nations troops increased significantly, and the war situation stabilized. While the aggression of foreign civilizations has not diminished, anti-aggression wars continue.
