A green train bound for Shanlan Terminal, filled with passengers returning home, had an accident at Changheng Transfer Station and stopped on the tracks inside the station. The carriage carrying the pollution source exploded from the inside, and the iron sheet of the carriage exploded from the inside out, splitting the train into two, and the pollution source inside was scattered by the explosive airflow. The pollution source is not affected by the extreme environment and does not need to be attached to anything. It spreads quickly, staining the grass along the railway line, splashing on people waiting for the train, and sucking the life out of them.
Expanding its territory, nothing seems to be able to restrain it.
All existing scientific and technological communication methods have failed, and they are cut off from external information. They have tried their best to break through the field of pollutants, but found that there is still an artificial blockade on the outermost periphery.
Intention: free will, unyielding soul
