Gatekeeper

Three hundred years after the resurgence of spiritual energy, modern society has been deeply integrated with the system of cultivating immortals. Employees in the Qi refining period are hidden in skyscrapers, and subway security inspection machines can identify low-level magic weapons. The "porch", the square inch of land that connects the home and the outside world, is recorded as the "air port" by ancient traditions. It is a key node for the residence to gather spirits and block evil spirits, but it has been forgotten by most people due to the process of urbanization.
