Black Law Survival: the Traveler of Global Live Broadcast

When I strayed into a strange city, the only thing I could rely on was the "Black Law of the Arctic Exorcist Academy" that I got by chance. There is no system in this world, no golden fingers, only evil spirits everywhere and other time-travelers who want to kill me. Until I discovered that my life and death were directly related to the fate of the motherland - for every compatriot who died, thousands of people died suddenly in the country. And my hair sent a message through a special method: "Hang on, we are looking for you to come home." But I don't even know if I can survive until the sun rises tomorrow.
