Underground in Linjiang City, a seemingly prosperous modern city, there are nine major families that have been passed down for hundreds of years. Each family masters ancient powers or secrets and secretly guards nine "secrets of heaven and earth" that are related to the destiny of the country. Technology and ancient secrets are intertwined, and overt business wars and secret power confrontations coexist.

At the end, Zhang Qifeng received an anonymous message: "Your father is not dead, there are traitors in the Nine Sects."
