Places Other Than Line 6

In 2043, that is, 23 years ago, humans on the ground were wiped out by a deadly ray. The older generation called it the Moonlight Incident. For some reason, the rays could not penetrate the surface, so people who were active underground at the time were able to escape. The surviving people mainly live in the six underground subway lines. The protagonist Jiang Xiyang lives in Line 6 among them. Jiang Xiyang's father's whereabouts were unknown during the Seed Project after the Moonlight Incident, leaving him with only an orange ore of unknown use. It seems that his father can use it to exert magical effects, but Sunset has still not been able to master the use of the stone. In the past six months, Xiyang has repeatedly dreamed about what happened during the Seed Project. At the end of the dream, his father would yell every time, telling his son to find him when he grows up. Sunset was tired of the life on Line 6. He decided to violate the public security regulations and leave Line 6 for the first time in his life to find out where his father disappeared.
