I, the Holy Son of the Sect, Will Check into the Forbidden Area for a Hundred Years!

Traveling through the fantasy world, he became a canonized saint and was imprisoned in the sect's forbidden area. Unexpectedly, the sign-in system was activated because of this. "Ding, congratulations to the host, you successfully signed into the forbidden land, and you will be rewarded with a thousand-year elixir." "Ding, congratulations to the host, you successfully signed into the library, and you will be rewarded with a heaven-level magic weapon." "Ding, congratulations to the host, you successfully signed into the sect's dragon vein, and you will be rewarded with a heaven-defying skill."... I kept checking in silently, and finally one day, Wushangmen faced a disaster of annihilation. He finally drew his sword!
