Purple Fire Era

Core worldview Time: In 2157 AD, the comet "Tears of Noah" crashed into the earth. Disaster: The comet carries a retrovirus from 4.3 Billion years ago, and 99.7% Of humans die or mutate within 72 hours. Three types of survivors Mutants: Lose language and self-awareness after infection, retaining only instincts. Evolvers: A very small number of people acquire supernormal abilities, but this comes with the risk of genetic collapse. Scavenger: Only 0.1%, Carrying natural inhibitory factors in the body. Blood is the only serum that can inhibit gene breakdown. Deep truth Ancient Placenta: Meteorites brought to Earth 4.3 Billion years ago. It is not a fossil, it is not an evolutionary code, it is the last letter sent to the universe by a perishing civilization. Corpse Borrower: The alien remnants after the Messenger awakens. The home planet has been dead for 4.3 Billion years. They came to Earth not to invade, but to retrieve the letter sent 4.3 Billion years ago. Black Mud Matrix: The original life on earth was born in seafloor hot springs 3.8 Billion years ago. It is the common ancestor of all life on earth and the "old knowledge" of the placenta. It slept for 3.8 Billion years and was awakened by the awakening of the messenger. Dean: Founder of the Old God Society. Twenty-three years ago, the placenta was dug out in Antarctica, infected by the debris, and became a hybrid of humans and alien survivors. He didn't dare to break the letter and face the truth about his demise 4.3 Billion years ago, so he pretended that this was an evolutionary code and that he could become a god. Lin Yuan: A twelve-year-old scavenger. His inhibitory factor is not immunity, but the "brake" planted by the mother 3.8 Billion years ago. He is the key to the brake and the real recipient of the letter 4.3 Billion years ago.
