A long time ago, there were three races in the world: the spirit race, the human race and the alien race. Lin Lan received a case one day. The primary goal was to find a spirit tribe, but he was unknowingly involved in deeper events, such as the code-named 0457 incident a hundred years ago, the gentleman in the dream, the forgotten desert island, etc. Xu Yu, as the spirit watcher of the Spirit Clan, not only had to protect the Spirit Clan but also help the human race. Thousands of years had brought him too many scars. He once thought about letting go and leaving at the end, but at that time he was no longer alone.
Concept: Xu Yu's lovelessness and Lin Lan's persistent love are two extremes. I hope that when people like Xu Yu devote their lives to their careers, there will be someone like Lin Lan standing behind him, so that Xu Yu can still have a trace of nostalgia for this world.
