Apostle of Time Mandarin version

60 years ago, an unprecedented "insomnia" hit the world. People who couldn't sleep became mentally ill one after another. Suicides and serious violence also occur frequently and become a major social problem. Although the situation gradually stabilized with the development of new pharmaceuticals. However, due to the side effects of the medicine, 2 billion people became ill, and new life forms such as "bloodthirsty species" were occasionally born. After that, a war broke out between the "bloodthirsty species" and humans. Although it ended in victory for humans, the remaining bloodthirsty species still exist in this world... In the end, humans relied on artificial blood and a bloodthirsty species management system called "D-GPS" to protect the survival rights of bloodthirsty species. This story takes place on a stage where humans and bloodthirsty species coexist as daily life.
