Backtracker Z

When the civilization of the planet suddenly disappears, when there is no history in human memory. It's like a clone here, with no place of origin and no source. Human beings are like small parts that make up a large machine, without thoughts and souls. But there are always some people who are different! They long to know where they were born and where the world came from, and they explore buried secrets. Zhou Fan, on the surface, is the owner of a hardware store, but in fact he was born into the third generation of a mysterious family. One day, a strange ring brings him into a team. This group of people has a common name - the Backtrackers. There is a special person among them - Shang Zhi, a mysterious man who is burdened with heavy secrets and responsibilities, a "god" who was left behind by the "gods". What is he hiding? What are we looking for?
