Black Rain Restricted Area

In 1943, a mysterious sample from Siberian permafrost showed abnormalities in a secret laboratory in Harbin. The experiment was continued, personnel were wiped out, and a codename appeared on top-secret files for the first time - **Yellow Springs**. Ninety-one years later, a black rain fell on Lanjiang City. The first ones to lose control were ants, followed by spiders, mice, birds... More and more life began to alienate along unknown directions. Environmental microbiologist Gu Chenzhou was accidentally infected during his investigation, and black marks appeared on his arms that could not fade away. He gradually discovered that the things that were turning into "monsters" did not seem to have completely lost consciousness. As Lanjiang became a restricted area, experimental files, lurkers, alienated humans, and thirty-seven black rain restricted areas around the world that had been hidden for half a century surfaced one after another. Conventional weapons gradually became ineffective, and humans began to create mechas that only aliens could pilot. Each time they were piloted, Gu Chenzhou was taking one step further away from being a "human". It wasn't until all the black rain started to gather towards Lanjiang that he realized that what was really waiting for mankind was never a disaster. But a world that has been sleeping for millions of years.
