Amnesia Crisis

In 3090, a war broke out between humans and robots, and humans were defeated. The captives had their memories erased by robots and were exiled to an isolated island, becoming poor amnesiacs. They don't know that the reality is already the 30th century, and they think they are living in the 21st century. However, among this group of amnesiacs, there is a young man with a mysterious "war power fire". He is destined to become the leader of the human rebels. Take the surviving humans to defeat the machine empire and build a new paradise.
