The year is 2033. The Earth is experiencing the inevitable development of technology and the entire society. People use the latest technology to improve their education, work, entertainment, health and communication. They also use them to reduce carbon emissions, produce renewable energy and fight global problems such as poverty, disease and inequality. Sounds too optimistic for humans, doesn't it?      And although bionic chips and prostheses have long been no longer a novelty, but rather a common phenomenon that can be found on the streets from New York to Beijing, everything is not so ideal. There was no end in sight to the conflicts between the states, and the common people were always looking for a way to exist.
