I don't know any novels about the zombie emperor. But if this is a fictional story, I can give some possible plot and character setting suggestions: - The setting of the story was set in an apocalyptic world where humans were already facing the threat of the zombie virus. Yun Shiya was a brave girl. She had a strong combat ability and a witty mind, and she became a zombie hunter. - The Zombie Emperor was a powerful zombie leader. He or she had great power and cruel means to rule the entire Ending Sun World. Yun Shiya might start a fierce battle with the zombie emperor. In order to protect herself and the others, she would do anything. - Yun Shiya might establish a special connection with other characters. For example, she might fight with a hero character or a trustworthy companion. These characters might play an important role in the story to provide more support and help to Yun Shiya.
