Neptune Chronicle

The robot on Neptune learned to think, and humans later named this special robot Robot. Humans and robots jointly built a glorious city, Diamond City. In a small village called Sanyandi outside Diamond City, Chen Ming accidentally got his robot, Zuo, and they worked hard to build their village into a new city. The forces in Diamond City were surprised by the rise of small villages and adopted various means to combat and contain them. After experiencing various difficulties, Chen Ming and Zuo finally defeated the city lord of Diamond City, but found that there was a greater challenge hidden behind all this.
