After Signing for a Hundred Years, I Became the Boss of the Demon Cult

The young man's cultivation was abolished and he was forcibly taken to the Demon Sect to become a disciple of the Demon Sect. At this time, a sign-in system came into being. As long as you sign in every day, you can get a random reward! "Ding! Congratulations to the host for successfully signing in and getting the Yiyang Dingtian Finger!" "Ding! Congratulations to the host for successfully signing in and receiving the dragon-slaying sword!" "Ding! Congratulations to the host for successfully signing in and receiving the Eighteen Dragon Subduing Palms!" "Ding! Congratulations to the host for successfully signing in and obtaining the Nine Yang Magic!" In this way, after living in silence for a hundred years, the boy was born, only to realize that there was no rival in the world!
